Synthetic high and low temperature lubricant
For lubrication and protection of rolling and sliding bearings at high and low temperatures.
- 60 ℃ ~ + 250 ℃.
Excellent lubricity, high and low temperature, rust resistance and long bearing life.
Lubricant a lubricant used to reduce the friction resistance of friction pairs and reduce their wear. Lubricant can also play a cooling, cleaning and pollution prevention role. In order to improve lubrication performance, suitable additives can be added to some lubricants. When choosing lubricant, it is generally necessary to consider the movement of friction pair, material, surface roughness, working environment and working conditions, as well as the performance of lubricant and other factors. In mechanical equipment, lubricants are mostly distributed to the parts that need lubrication through the lubrication system.
The lubricant can lubricate because it can reduce the friction of ya-plastic melt, which can be divided into internal friction and external friction. Accordingly, there are internal and external lubricants.
1, outside lubricant mainly improve polymer molten material and equipment of hot metal surface friction condition, easy stripping plastic, poor compatibility with polymer, it easy to migrate from the molten material, in the molten material in the course of forming process and mould form a very thin layer of isolation film, make plastic do not stick to the mold surface.
2, the internal lubricant and polymer have good compatibility, it plays a role in reducing the cohesion between polymer molecules in the polymer, so as to improve the internal friction heating of plastic melt and melt fluidity. The bonds between the internal lubricants and the long chain of polymer molecules are not strong, and they may act like rolling bearings, so that they can align themselves in the direction of melt flow and slide against each other, reducing the internal friction. This is the mechanism of internal lubrication.
