Air compressor oil has strong oxidation stability at high temperatures, good lubricity, and good oil-water separation effect.

With high-quality antioxidant benefits, it can avoid condensation water damage.

Turbine oil (also called turbine oil or turbine oil), the English transliteration of the word "turbine" for steam turbine,

The main difference between turbine oil and other lubricants is that it is better

"Antioxidant stability" and "Anti-emulsifying properties",

Mainly used in power plant steam turbines and hydropower station turbine generators

and other lubrication situations that require deep and refined lubricating oil. Turbine oil is a kind of engine oil used in steam turbine engines.

Suitable for high-speed machinery lubrication, mainly plays the role of lubrication, heat dissipation, cooling and speed regulation.

Slag remover is used to treat the slag produced in the foundry during the melting process.

The use of slag removal agents to collect slag or other impurities can prevent slag holes in castings.

The characteristic of the slag remover is its excellent slag-sticking effect.

And the toxic smoke and waste gas generated during the application is significantly less. In pouring applications,

It can effectively solidify impurities and allow the dissolved metal liquid to be smoothly poured into the mold.

When needed, the slag remover can form a highly efficient insulation layer to maintain the temperature of the molten metal.

Application scope:

Gray cast iron/ductile iron/cast steel/alloy steel/stainless steel/copper alloy

How to use:

Induction electric stove: Using a slag remover before cooking water can reduce heat radiation production and shorten heating time.

The coating agent is a silver-white paste coating, suitable for aluminum, magnesium, copper, zinc and other alloys.

It is made of inert metal refractory mixed with a little graphite and a special high-temperature resistant binder.

A brushing agent that prevents molten metal from sticking. Form a protective film on the surface of metal tools and the lining of metal crucibles.

The materials used in the coating agent are all high-purity special products. When in contact with molten metal,

No impurities will be produced and the molten metal will not be polluted.

Note: Iron tools in contact with molten metal when melting aluminum, magnesium, copper, zinc and other alloys are often susceptible to corrosion by the molten metal, resulting in a small amount of iron being melted into the molten metal. When aluminum is melted, the strength and toughness of the alloy will be seriously affected.

When making copper and zinc alloys, the inclusion of iron will cause slag inclusions at hard points, making processing difficult.

Therefore, during the melting process, all iron tools that come into contact with the molten metal, such as milling iron crucibles,

Metal thermocouple protection rods, ladles, ladles, covers, slag cakes, etc.

All must be coated to isolate the contact between iron and molten metal. It has high fire resistance and strong adhesion.

Features: 1. Extremely strong adhesion and easy to use.

2. Convenient for cleaning tools and milling iron crucibles.

3. Extend the life of iron tools and iron milling crucibles.

 

Usage: 1. Clean the tool first, and then apply it on the surface of the tool with a brush.

Then slowly immerse the tool completely in the aluminum soup for about ten seconds and immediately pick it up and use it.

2. You can also place the iron tool to be painted on the stove to heat it, and then brush the coating agent on the surface of the tool.

Then slowly and completely immerse the tool in the aluminum soup and take it out in about ten seconds before use.

4. Reduce the risk of contamination of molten metal.

What is a release agent (release agent)?

A treatment agent applied to the mold when synthetic resin or synthetic rubber is molded using a mold. Like oil on a pan, it creates a protective film on the mold surface that prevents the molding material from adhering to the mold.

Release agents (release agents) are used in the molding of products in many fields, such as tires, bumpers, gaskets, etc. in the automotive industry, and sporting goods such as golf club heads, tennis rackets, fishing rods, etc.

Types and characteristics of various release agents (release agents)

Fluorine release agent (release agent) -

Silicone (silicon) type release agent (release agent) -

It has the lubricity of silicone oil and good mold release properties and is widely used.

The disadvantage is that the oily coating film is fluid and can easily cause mold contamination and transfer to molded products.

Not suitable for areas requiring secondary processing and precision molding.

Furthermore, do not use it when molding electrical parts because it may cause poor conduction.

Wax release agent (release agent) -

Thick coating will cause the mold to become dirty and the demoulding properties to deteriorate, so it is generally not used.

The wax transferred to the molded product is relatively easy to clean, so it is used for molded products that require post-coating.

Surfactant type release agent (release agent) -

It has poor mold releasability but is cheap. It is used for molding molding materials with simple mold release and products with low added value.

Lubricant Additives are ingredients in lubricants.

In general industrial lubricants, greases, pastes or waxes

They all contain various lubricant additives with different ingredients.

The function of some additives is to improve the physical properties or lubrication performance of the lubricating product itself.

Additives used to improve lubrication performance are also called lubricity additives (Lubricity Additive).

Many additives are multifunctional.

Lubricant additives are the core technology of industrial and vehicle lubricants.

Different additives not only have different functions,

They may also have synergistic or antagnostic effects on each other.

Different additives have different solubility in different base oils.

Therefore, the core technology of industrial special-purpose lubricants is the additive package.

Many lubricant manufacturers use standard additive packages developed by additive manufacturers.

Or you can purchase additive combinations from major lubricant brands and mix them yourself to prepare the finished lubricating grease.

There are many types of lubricants, which are mainly used to lubricate mechanical parts and reduce equipment friction.

Achieve antioxidant and anti-wear effects,

Including hydraulic oil, slide oil, spindle oil, spindle oil, circulating oil, gear oil...,

TOMKER provides various brands of industrial lubricants,

Including MORESCO Japan Matsumura Oil, COSMO, CPC Guoguang, MOBIL Mobil, SHELL Shell.

In the industrial lubricant category, hydraulic oil and slide oil are essential oils.

Most processors will require you to specify the serial number and viscosity. The number in the serial number is not equal to the viscosity.

It is a unified standard specification of ISO. The larger the number, the higher the viscosity.

Among them, the most common ones are ISO32, ISO46, ISO68

Three grades of hydraulic oil and slide oil are mainly used.

Customers often ask about the common properties and differences between slide oil and hydraulic oil. Although the grades are the same,

But the two are still different in their main functions.

The slide oil is between two relatively moving objects.

It has cooling, anti-rust, cleaning, sealing and buffering properties,

The main function is to reduce the friction caused by contact between two objects;

Hydraulic oil is used in hydraulic systems,

Performs functions such as energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc.

It is a special oil that transmits pressure (power).

Rust Oil is a solvent that can protect metal surfaces to varying degrees.

Prevent metal products from oxidation, rust, and discoloration caused by environmental problems.

Rust Oil has a wide range of uses.

Can be used in various applications such as industry, metal manufacturing, automotive, navigation, etc.

The purpose is to protect against moisture, rust, and corrosion, etc.

Anti-rust oil (Rust Oil) will vary depending on the material, manufacturing process and other requirements.

The required anti-rust strength and timeliness will also vary.

The method used will also vary depending on the type of solvent.

They are divided into volatile, non-volatile, grease and other anti-rust oils.

It is also divided into short, medium and long validity periods according to the timeliness.

Anti-rust oil, anti-rust grease (RUST OIL)

Gear Oil is formulated based on base oil and added with lubricants and extreme pressure anti-wear agents.

It is mainly used between gears and bearings to prevent wear and rust, and effectively helps gears dissipate heat.

As gears and bearings rotate, surface pressure increases due to temperature.

It is easy to cause tooth surface cracks, wear, sintering and other problems.

Therefore, the lubricity, cooling and heat dissipation properties of gear oil are even more important.

Therefore, in gear transmission devices, gear oil can reduce friction and transmission losses between gear transmissions.

Reduce tooth surface impact and transmission noise, not only improve mechanical efficiency,

It can also protect the normal operation of transmission parts.

Hydraulic Oil can also be used as circulating oil. It is the most commonly used oil in industrial oil.

Hydraulic oil functions as a medium for transmitting liquid pressure.

So that the equipment can fully achieve the

Transmission, conversion, anti-wear, lubrication and other effects to maintain the normal operation of the hydraulic system,

At the same time, hydraulic oil (Hydraulic Oil) can also protect the machine and prevent components from rusting.

Hydraulic Oil can be used in a wide range of mechanical equipment.

Therefore, it will also be targeted at severe environmental conditions.

Blending suitable oil products to maintain the stability of the hydraulic system,

Ensure equipment can operate normally and extend service life in harsh environments

, and also according to various viscosities are AW32. AW46. AW68.

These three viscosities are the most commonly used on the market.

Slideway oil (slideway-oil) is also called slide rail oil, guide rail oil, and carriage oil. It is mainly used on the surface of the slide rail.

It can help transmit, convert and control hydraulic energy. By adding a variety of extreme pressure lubricants,

It can effectively lubricate the bed slide rails of various high-load and machine tools.

Avoid the phenomenon of machine surface jumping or the wear of slide rails under high-load operating conditions.

It can also prevent corrosion of parts and equipment.

Slideway oil (slideway-oil) is suitable for various medium and high-sized machinery, heavy-duty working machines, slide rails, ball shafts, etc.

And also according to each viscosity respectively VG32.VG46.VG68,

These three viscosities are the most commonly used on the market.

Oil Base Cutting oil,

Use low viscosity mineral oil as the base and add additives for mixing.

There is no need to add water for dilution during use and can be processed directly.

Oil Base Cutting oil is widely used and is suitable for light to heavy machining and various material processing.

Because of its excellent lubricity and anti-rust properties, which are higher than water-based cutting oil,

It is also commonly used in finishing manufacturing, and the wear on tools is relatively lower than water-based cutting fluids.

Oil Base Cutting oil has low consumption and long service life.

It can save costs and at the same time protect the machine equipment from oxidation and paint corrosion.

Its disadvantage is that it easily generates oil, gas and processing waste gas, and the on-site environment is relatively messy.

The workpiece is also greasy, requiring an additional cleaning procedure which is more troublesome.

water-base cutting oil,

Suitable for processing various metals and components and adapting to various processing conditions.

Water-based cutting oils are roughly divided into three categories: fully synthetic cutting fluids, semi-synthetic cutting fluids, and emulsified cutting fluids.

Water-base cutting oil has excellent cleaning properties and

It has cooling performance and anti-rust protection effect, and the processing process is not prone to oil smoke and machine tool stickiness.

Low fuel consumption, must be diluted with water before use.

"Cutting fluid foaming"

During the cutting process, cutting fluid foaming is an annoying problem, because once it foams, it will easily affect the performance of the cutting fluid and affect the quality of the finished product. Most customers will use defoamers to suppress foaming, although the effect is It is fast, but it still cannot solve the foaming problem in the long run, and using too much defoaming agent will destroy the performance of the cutting fluid. In the end, new oil must be replaced, which also increases the cost of oil replacement.

Effect of foaming on cutting fluid:
 

1. The oil tank is filled with a large amount of foam and overflows, making it difficult to directly observe the entire processing process.

2. Changes in the performance of the cutting fluid directly affect the processing effect of the metal and can easily cause oxidation and rust.

3. Foaming will cause a waste of cutting fluid, requiring constant addition of new oil, increasing costs.

4. The environment is messy and sticky, requiring more manpower to maintain cleanliness.

When foaming occurs in the oil tank, you must first find out the cause and analyze it to find the source of cutting fluid foaming:

1. Water quality problems: Water quality that is too soft or too hard can easily cause foaming.

2. Human factors: The oil tank is not cleaned frequently or there are other foreign objects, such as cigarette butts, garbage, rags, etc., or there are too many iron filings that are not fixed and cleaned.

 

3. Equipment problems:

▲ The oil tank space is small, the water tank has too many right angles, resulting in poor fluidity, or the nozzle point of the cutting fluid is too straight.

▲ If the water pressure is too high and the flow rate is too fast, the bubbles will flow directly back to the sink before they subside, accumulating more and more, resulting in a large amount of foam.

▲ The hydrocyclone separator used to separate solid particles is not positioned correctly, cutting through the hydraulic conveyance of the cutting fluid nozzle.

▲ As the motor speed and pressure increase, the scouring force of the water column becomes stronger, causing bubbling.

4. Oil performance:

(1) The cutting fluid itself has poor defoaming ability.

(2) The cutting fluid has poor anti-oxidation stability and will also cause foam to occur quickly.

(3) If the concentration of the cutting fluid is too high, it will easily lead to the generation of foam. The smaller the viscosity of the cutting fluid, the easier it will be to generate foam.

(4) The original solution is not added regularly, and the cutting fluid concentration and surfactant are insufficient, which affects the foam-cutting ability.

How to solve the blistering problem?

1. Add new cutting fluid at any time and pay attention to the concentration of the cutting fluid.

2. Avoid the liquid level in the oil tank being too low and check the liquid level regularly.

3. Clean the oil tank regularly to keep the oil tank environment clean. If too much cutting chips are deposited, it will easily lead to poor fluidity.

4. When using, pay attention to the angle of the nozzle to avoid right-angle flushing, and control the flow rate of the cutting fluid not to be too fast.

5. If the foaming problem occurs repeatedly, notify the oil dealer to replace it with another suitable cutting fluid.

Three major puzzles 1 – Why does it rust?

Metal materials will cause oxidation or rust due to the influence of external environmental factors.

Such as changes caused by bacteria, salt and various acid and alkaline substances in the air,

Especially in a highly humid environment, oxidation is more likely to accelerate.

Material is also a key factor. For example, iron and copper are the most susceptible to oxidation and rust among all materials.

But does this mean that any material will cause oxidation due to the reasons discussed above?

The answer is: not really. It’s just a matter of the length of contact with the storage environment.

In addition, when metal products are processed, such as cutting, lathes, milling machines, etc.,

Because the material comes into contact with the water in the cutting fluid,

If the cutting fluid (cutting fluid) itself has insufficient anti-rust properties or the concentration is not enough, corrosion will easily occur.

 

Three major puzzles 2 – Selection of anti-rust oil?

Rust Oil is a solvent that can protect metal surfaces to varying degrees.

A protective layer that blocks rapid metal aging,

Prevent metal products from oxidation, rust, and discoloration caused by environmental problems.

Therefore, anti-rust oil can be said to put metal workpieces in strong protective armor.

When customers ask for [I'm looking for anti-rust oil], the most common questions we ask are:

How long does your validity period take? Some customers may wonder that anti-rust oil also has a validity period?

I thought it would be fine as long as I put it on...

However, with the passage of time and the influence of the environment, the effectiveness of anti-rust oil will gradually lose.

Therefore, choosing the right anti-rust oil will be a key to preservation!

Anti-rust oil (Rust Oil) will have different requirements depending on the material and process section.

The required degree of rust prevention and timeliness will also vary, which is referred to as the rust prevention cycle.

The method of use also depends on the type of solvent, which can be divided into volatile, non-volatile, and grease-based anti-rust oils.

 

What is the material?

There are more than 70 kinds of metal materials, among which the common ones are iron, copper, aluminum, gold, etc.

And combine multiple elements to become various materials

Such as: nickel alloy, magnesium alloy, stainless steel, etc., and some materials,

In particular, materials such as iron and copper will rust and oxidize due to contact with air humidity.

It may also be related to the density of the material. The higher the density and the harder the material, the lower the chance of rusting.

Anti-rust time?

After processing, they will be divided into finished products and semi-finished products. Most of the semi-finished products will only be stored for up to three months due to cost constraints.

The finished products will be stored for at least one to three years after being put into storage.

Therefore, anti-rust oil has three types of aging: short-term, medium- and long-term, and long-term:

Short term rust prevention: 3 months

Mid- to long-term rust prevention: 6 months to 12 months

Long-term anti-rust: more than one year.

Storage environment?

The material will also be affected by the storage method. For example, if the humidity of the space environment is high,

or may be easily exposed to chemical gases and dust, as well as various factors such as the location and manner of placement.

 

It is also recommended not to place them together with different materials at the same time.

 

Geographical environment?

For example, Taiwan has a high-humidity, muggy, and harsh environment, and the air is mixed with a lot of water vapor and molecular bacteria.

It is a breeding ground for mold and rust, especially in coastal areas where the salt content in the air is high.

It is easier to accelerate the oxidation of materials, so residents living near the sea are most likely to have electrical appliances break down.

Or it’s easy to see mottled walls and rusty metal equipment.

Three major puzzles 3 – How to use anti-rust oil?

Anti-rust oil has a wide range of uses and can be used in various applications such as industry, metal manufacturing, automotive, navigation, etc.

The purpose is to protect against moisture, rust, and corrosion.

According to usage and needs, anti-rust oil can be divided into the following three commonly used types:

Immersion type: Soak the material in anti-rust oil, wait for the surface and interior to be evenly absorbed, then take it out and dry it.

Suitable for various small and medium-sized metal parts.

Spray type: Use spray method to spray anti-rust oil on the metal surface.

Suitable for parts and localized rust prevention in large areas or large equipment.

Smearing method: Apply anti-rust oil to the surface of metal products. This method is more suitable
for large workpieces or products with complex shapes.

 

How to prevent workpieces from rusting:

1. Measure the cutting fluid regularly during processing and ensure good management of the cutting fluid concentration.

2. Carry out one-time work as much as possible to avoid secondary processing that reduces cycle time and makes cleaning difficult.

3. Try to store the workpiece in a dry environment or control the temperature and humidity of the environment. For example, you can place dehumidification equipment in the indoor space to avoid exposing the workpiece to the sun. The hot sun will also promote the chemical reaction of oxidation.

4. Before using anti-rust oil to prevent rust, you need to pay attention to whether the workpiece has been cleaned and dried. If the workpiece has been rusted, you need to use rust remover to remove the rust first to prevent the rust from spreading and affecting the workpiece. Anti-rust oil performance.

5. Anti-rust bags, anti-rust paper and other packaging materials can be used to prevent rust. Some operators will add a little anti-rust oil to the packaging materials to improve the anti-rust effect. This method is mostly used for shipping and long-term storage.

6. Choose the correct anti-rust oil. Depending on the nature of use, such as pre-processing, secondary processing, storage after processing, etc., the timeliness will be different.

Today we are talking about how to "prevent workpieces from rusting"

As long as it is made of metal, it will rust over time and the influence of the environment.

And in the process of using anti-rust oil on metal,

Workpieces may still rust even after using anti-rust oil.

So it’s not that after using anti-rust oil, the above problems will no longer occur.

It’s just a matter of storage environment, contact and length of time, and each anti-rust oil has its own timeliness.

It can also be divided into short, medium and long aging. If you choose the wrong aging, it is easy to cause rust.

Reasons for easy rusting after using anti-rust oil:

1. Environmental factors: Metals will be oxidized or rusted due to external environmental influences, and changes will occur due to the presence of more bacteria, salts, and various acid and alkaline substances in the air, especially in high-humidity environments. More likely to accelerate oxidation.

2. Material factors: Some materials are more likely to rust and oxidize, such as iron, copper, or alloy steel with a high iron content. Such materials are more likely to oxidize and rust.

3. Storage environment: The material will also be affected by the storage method, such as the space environment with high humidity, or easy exposure to chemical gases and dust, as well as various factors such as the location and method of placement.

4. Not kept dry: If the workpiece is not wiped clean before applying anti-rust oil after manufacturing and there is still moisture left, it will easily cause rust.

The main problem of oil-water separation comes from "water quality". If the same cutting fluid is used in areas with different water quality, the performance of the cutting fluid will be different. If you often change cutting fluids of different brands, the performance of the cutting fluid will be different. It will cause oil-water separation, so you need to consider your local water quality conditions before choosing a suitable cutting fluid to avoid wasting processing costs.

How to prevent oil-water separation?

1. Soft water and cutting fluid need to be mixed, but if the water is found to be hard, a water softener can be installed to soften the water.

2. Add cutting fluid regularly to maintain a balance between concentration and PH value to avoid encouraging bacterial growth.

3. When replacing new oil, the cutting fluid and oil stains around the machine tool and in the oil tank must be cleaned first, and disinfected with bactericide before injecting new fluid.

4. Regularly remove iron filings and sediment from the oil tank to reduce the risk of water pollution.

5. When mixing cutting fluid and water, add water first and then the cutting fluid so that the additives of the cutting fluid can be fully mixed with the water and evenly coated.

6. Choose a cutting fluid that is resistant to hard water

"Oil-water separation" means that after the water and cutting fluid are mixed, the cutting fluid is separated from the water. It is very obvious by visual inspection. This phenomenon is easy to occur during the machining process. Although there are ways to use additives to temporarily Mix the oil and water back, but it won't last long. In the end, you need to recheck the water quality and select a suitable cutting fluid, which can solve the problem completely.

Two major reasons for oil-water separation:

1. Impact on water quality:

When using cutting fluid, you need to add water and mix it before adding it to the machine. If the water quality in the area is moderately hard, especially in coastal areas, the water quality is close to hard water, and hard water contains a large amount of magnesium ions and calcium ions. and a variety of minerals. These elements will cause saponification of the cutting fluid. The higher the hardness of the water, the more serious the turbidity will be. When the cutting fluid is mixed with water, water accounts for almost 90% to 95%, while the cutting fluid The water content is only 5~10%. If the water quality is too hard, the emulsification of the cutting fluid will be unstable and oil-water separation will occur, which will also prevent the original cutting fluid from playing its due role. Hard water contains a large amount of sodium and potassium, which can corrode machine tools and workpieces and easily cause oxidation and rust.
