- Q:Aging test report of rubber sealThat is to say, rubber sealant is how anti-aging
- (E) mechanical stress in mechanical stress under the repeated action, will make the rubber chain fracture generation of free radicals, causing oxidative chain reaction, the formation of chemical process. The mechanical fracture of the molecular chain and mechanical activation. The oxidation process which can be dominant, depending on the conditions. In addition, the stress under the action of easily lead to ozone cracking.(f) the role of water: water has two aspects: rubber in the humid air or rain soaked in water, easy to damage, this is because the rubber in water soluble substances and water groups by water extraction components dissolved. By hydrolysis or absorption of reasons. Especially in the alternate action of soaking water and air exposure, will accelerate the destruction of water. But the rubber rubber is not destructive in some situations, and even delay the aging effect.(g) other: on the role of rubber and chemical factors of medium, valence metal ion, high-energy radiation, electrical and biological fields.
- Q:What is the function of the seal?
- The seal can be divided into rotary shaft oil seal, seal, dust ring, piston and piston rod seal and so on, a lot of daily life to sound like dust and waterproof, oil seal for many industrial equipment, such as waterproof and dustproof.
