| Guangdong Xing Rui electronic silica gel products factory before tells a lot about silicone products in the field of professional knowledge introduction, but few seem to have written about silicone products purchase should pay attention to the factors, then following Guangdong Xing Rui electronic silicone products factory will take you to understand what we in the purchase of silicone products need to pay attention to what factors? Here silicone products category includes "silicone keypad, silicone keypad, silicone masks, silica gel cup mat, watches, and so on a series of silica gel raw materials and finished products, hope to help readers. First of all, to see the silicone products are the important factors in good quality is elastic, known as silica gel is flexible, good silicone products, high elasticity, high elasticity is mainly from the silica gel, molecular chain segment movement, for the user to say elasticity is primary investigation. Secondly, the tear strength and tensile strength of the silicone products, high tear strength silicone products anti damage ability outstanding, with a long service life is less susceptible to outside interference, poor tear strength of silicone products, general performance in tear cracks easily occur, to force rapid expansion of cracking and lead to the destruction of the phenomenon. Also see the abrasion resistance of silicone products, wear resistance of general performance in the surface of the silica gel product is easy to suffer from loss of ability and good silicone products general surface rarely by external factors, friction off the surface of the product, does not affect the appearance, characters and color. Then, to look at the hardness and tensile stress of silicone products, they are reflected in the important index of rubber material stiffness (stiffness), the two are necessary to produce a certain degree of deformation of silica gel. Finally, look at the fatigue and fatigue failure of silicone products and fatigue damage, silica gel products by alternating stress (or strain), the structure and performance of the material changes in the phenomenon called fatigue. With the fatigue process, leading to the destruction of silicone products called fatigue damage. |
