Damping grease (lotime) is made of special polymer base oil and high-purity thickener and added with anti-rust, waterproof, corrosion-resistant and other additives through a special process. It is a widely used high-resistance grease, mainly for The slow switch mechanism with large resistance requirements is designed with blocking, buffering, and waterproof sealing, so that the moving parts can operate more smoothly, smoothly and accurately.
Classification and function of damping grease
1. Damping grease type:
1. Polybutene type damping grease: It was found that ordinary soap-based greases such as calcium-based, lithium-based, etc. feel too bad for the hand, so the initial damping grease was made using polymers as base oil. The commonly used polymer is polybutene, and the commonly used thickeners are silica, bentonite or fatty acid metal soap. The biggest disadvantage of this type of grease is its poor viscosity and temperature. Polybutene decomposes at high temperatures to make the grease hard, and at low temperatures the grease will solidify.
2. Polysiloxane type damping grease: The advantage of this type of damping grease is that it has good viscosity-temperature properties but low adhesion and poor lubricity.
3. Polybutylene + polysiloxane type damping grease: This type of damping grease combines the advantages of the first two types of good lubricity, good adhesion, and good viscosity-temperature.
4. Ethylene, olefin polymer type damping grease: The lubricity of this type of damping grease is equivalent to that of polybutene damping grease, and the viscosity-temperature property is between polybutene and polysiloxane type damping grease.
2. Damping grease function:
Damping grease is used in most mechanical and electronic mechanical instruments to control free movement and reduce noise. In the focus adjustment of optical instruments, the damping grease can control sliding to ensure smooth and silent operation. In electronic control, you can use your hands to make precise settings. In addition, in gear systems, home appliance control, electronic switch mechanisms, outdoor entertainment equipment, laser control, TV tuning, measuring instruments, etc., manually control activities and reduce noise. Due to its own viscosity, the damping grease can also prevent the instrument from being exposed to moisture, dust and other contaminants, avoiding complete closeness between moving parts, which reduces wear and extends product life.
