Perfluoropolyether grease, commonly known as fluorine grease, is refined from
polytetrafluoroethylene (PTFE), perfluoropolyether (PFPE) and additives. It has
excellent thermal stability, chemical inertness, low saturation vapor pressure,
good lubricity and viscosity-temperature characteristics. In the field of space
machinery lubrication, especially in the lubrication of some components with
high precision requirements, it has been widely used, mainly in the following
areas.





(1) Chemical industry: PFPE is used as working fluid in various vacuum pumps
[rotary pumps, turbo-molecular pumps and vapor diffusion pumps]; when there are
corrosive gases in the operating environment, PFPE is used as lubricating oil
for compressors and valves.


(2) Electronics industry: the use of plasma etching, LPCVD and plasma
cultivation and other technologies to produce semiconductors to be used in a
number of vacuum mechanical pumps, and PFPE as a vacuum mechanical pump
lubricant to achieve satisfactory results.


(3) Machinery industry: PFPE is often used as high temperature and chemically
stable porous metal bearings, conveyor belts, paper and textile machinery
lubricants, when used as a plastic bearing lubricant, its anti-wear ability to
improve when some electromechanical equipment (such as current contactors,
switches and buttons and sliding electrical contactors, etc.) in the need for
good lubrication and resistance to arcing is often to use PFPE lubricants.


(4) Nuclear industry: in the UF6 enrichment workshop, when the temperature is
higher than 130 ℃ when the lubricant is required to resist the chemical impact
of UF6, but also requires dry, dust-free and low vapor pressure, PEPE is allowed
to be used as a super-centrifugal bearing lubricant lubricant in such working
conditions.


(5) Aerospace industry: Because PFPE has a wide range of liquid temperature,
low evaporation, high static viscosity, very low vapor pressure, low flow
temperature and good high-pressure lubrication in the aerospace industry has
been used.


(6) Magnetic media industry: low coefficient of friction, low volatility and
good insulation make PFPE can be used as the lubrication of hard disk, magnetic
tape and other magnetic recording media on instruments such as juice calculator,
video recording and automatic recording device. 


The biggest characteristics of

good acid and alkali resistance. Most of the general food industry is used in
high temperature and longer lubrication cycle requirements of the position, and
seals. It can be said that the highest cost-effective products for
high-temperature environments, high temperature 200 ℃ to 260 ℃, its service life
than 300/F-YL products up to 10 times more than the cost-effective compared to
peers more than 30% lower.

In the working conditions of high-temperature equipment, mechanical equipment often works in a high-temperature environment for a long time, which will cause problems such as sintering corrosion, rust or wear of parts. Because these parts are difficult to disassemble, later maintenance becomes inconvenient. Many people choose destructive dismantling to solve the problem, but this will increase the cost of later maintenance and replacement and reduce work efficiency.



Few people will think about how to prevent this tragedy from happening. In fact, in the production and assembly process, just add a small action and use anti-bite agent in advance to avoid the inconvenience of subsequent maintenance and disassembly.When talking about anti-bite agent, many people may feel unfamiliar with it. Because anti-bite agent rarely appears in people's daily life, only a few companies will use it. If you have not been exposed to anti-bite agent, it is difficult to have an in-depth understanding of it. The following will introduce the performance characteristics of anti-bite agent in detail for a preliminary understanding.

What is anti-bite agent?

Anti-seizure agent is a high-performance paste lubricant that can be applied to various bolts and chains to protect threads from being exposed to high-temperature connections to prevent seizure and corrosion. It is an anti-wear and anti-seizure lubricant that has a good protective effect on industrial equipment components. It can also be used with sealing gaskets to make gasket sealing more reliable and easier to disassemble.



It is a product that can form a protective coating on the surface of parts. It has extremely high temperature resistance (Weiligu anti-seizure agent can withstand high temperatures of 1400℃), and is not easily soluble in water and will not be washed away or burned by water. It has excellent characteristics such as anti-oxidation, anti-seizure, anti-seizure, and corrosion resistance.



It is suitable for various scenarios, such as cutting of bolts, studs, screws, nuts, shafts, drills, taps, etc., especially difficult-to-process alloy materials; extrusion molds, heat exchangers, shear blades, metal bending, cold forging and warm forging, shear spinning, etc. It can provide lubrication and prevent metal sintering and seizure at high temperatures (up to 1400℃).



According to different product requirements, Weiligu provides a variety of anti-bite agents, and you can choose the product that suits you according to the actual situation.



Performance characteristics of anti-bite agents

1. High temperature resistance

Anti-bite agents are favored for their excellent high temperature resistance. In mechanical work, production operations are often required in high temperature environments. If the anti-bite agent used cannot withstand high temperatures, it will lose its function, making the use of anti-bite agents in machinery meaningless.

Therefore, anti-bite agents with high temperature resistance are very important.



2. Wear resistance

Anti-bite agents have excellent wear resistance. This advantage can effectively prevent the bite parts of threads and fasteners in industries such as machinery and construction from getting stuck. If the bite parts get stuck, it will affect the normal use of mechanical equipment.

Although the amount of anti-bite agent applied is not much and not very eye-catching, its role is very important and has a great impact on mechanical equipment.



3. Corrosion resistance

The application of anti-bite agent has no corrosive effect on metal parts and will not react chemically with metal parts. In addition, whether in an acidic environment, an alkaline environment or under salt water erosion, applying an anti-seizure agent will not affect its anti-seizure effect.



4. Good stability

The anti-seizure agent itself does not contain aluminum, lead, copper, chlorine, sulfur, fluorine and other compounds. Therefore, it can still maintain good adhesion in a high temperature environment and has the performance of preventing sintering.

In addition, the anti-seizure agent has good stability and will not react chemically with other materials. Under high temperature conditions, it will not solidify, coke or leak oil.



5. Good waterproofness

The anti-seizure agent has excellent waterproof performance. At the same time, it has good anti-rust and anti-corrosion properties. During the operation of the equipment, the torque can be stably maintained, and even repeated disassembly and tightening will not affect the torque. Even under harsh conditions such as static, humid, long-term high temperature or extremely high temperature, it can still ensure that the equipment parts will not be welded and stuck.Anti-seizure agents are widely used in equipment in industries such as steel, thermal power generation, chemical industry and cement under high temperature conditions. It can effectively prevent the sticking and corrosion problems of metal connectors in high temperature environments. Under ultra-high temperature conditions, anti-seize agents can reduce friction and wear and extend service life.

In addition, anti-seize agents are also widely used in industrial production processes such as casting and die-casting, providing excellent separation and lubrication effects and improving production efficiency. In the automotive industry, anti-seize agents can be used for assembly lubrication of spark plugs, cylinder threads, exhaust pipe flanges and other parts to improve automotive performance and safety.



In summary, anti-seize agents have excellent high temperature resistance, rust resistance, wear resistance and anti-seize functions, as well as excellent lubrication and corrosion resistance. It has a wide range of applications and can improve the service life and safety performance of equipment, while also saving time and economic costs for maintenance and repair. Jialede bite agent can be said to be an ideal choice for solving metal connection problems.

Waterproof sealing silicone grease is generally suitable for lubrication and sealing of O-rings and rubber sealing rings of cables, valves, bathroom equipment and aquarium equipment. It can also meet the sealing and lubrication between plastics and plastics, plastics and metals, and metals and metals.

The following points should be noted when selecting waterproof silicone grease:
1. Whether there are food grade requirements.
2. Material of the use part: Be sure to find out the material that the sealing part may contact. Although silicone grease is compatible with most rubbers, silicone grease is incompatible with silicone rubber. For example, silicone grease will cause silicone rubber to swell to a certain extent, which is not allowed in some cases. 
3. Good sealing and lubricity. Generally, sealing has a lot to do with the adhesion of oil. For parts with high sealing requirements, grease with good adhesion is generally selected, and for parts with high rotation speed, grease with good lubricity should be selected. 
4. Distinguish whether the parts that need sealing and lubrication are static seals or dynamic seals. The silicone grease selected in the two cases will also be different. Static seal: There is no relative motion friction or frequent movement in the sealing part. For example, the sealing rings at valves and cables are mostly static seals. Dynamic seal: There is relative motion in the sealing part, such as the piston of the water pump and the piston of the air pump are dynamic seals. 
5. Working temperature: Silicone grease has excellent high and low temperature performance. 

Jialede has products specifically for static and dynamic sealing. Fluorosilicone grease 1675 Food grade silicone grease (equivalent to Molykote DC 111) YBS-290 YBS-1672... If you need relevant product information, please contact our engineers immediately!
