Main lubrication problems of buffers:
※The viscosity-temperature performance should be excellent within the range of -20 to 40 degrees Celsius, the change is not large, and the change curve is gentle;
※For the corresponding damper products, the slow down speed can be guaranteed within the specified time;
※ During the cycle test, the viscosity of the oil does not change much to ensure that the resistance changes little;
※ Long service life, after the viscosity changes under temperature and shear, it can be restored for a period of time;
※Strict environmental protection requirements, many oils and fats have not passed the relevant environmental certification…
Solution:
※Imported silicone oil is used, and the high and low temperature performance is good;
※Choose the silicone oil that directly intercepts the viscosity to ensure low thixotropy;
※According to the structure of the damper and the gap size of the moving part, choose the silicone oil suitable for the viscosity;
※Fill in an appropriate amount of silicone oil to ensure the consistency of the resistance of the damping product;
※To meet the requirements of the current market, all toy products must meet environmental protection requirements…
