It causes the sealing ring skeleton to fall from the cavity, which is the elasticity of the outer rubber to the temperature compensation to ensure that the oil seal outer ring is closely fit to the cavity hole. Rubber Small Knowledge: Plasticizer increases the physical properties of low temperature ...

     To obtain an alumina ceramic material with high wear resistance, it is not only necessary to consider its high density, high flexural strength and compressive strength, but also to improve its hardness and fracture toughness, which are very different from alumina ceramics. The microstructure (c...

There are many related products made of ceramics, some of which are for decoration and some for industrial use. The performance of decorative ceramics is basically relatively simple, but the industrial use is different. In order to meet certain usage requirements, ceramics must have some special eff...
