Consoles silicone keys Dongguan Heng Heng Li Yawei printing equipment materials firm Silicone (Silica gel; Silica) Alias: Silicone rubber is a highly active adsorption material is amorphous material silicone products plant, its chemical formula is mSiO2 · nH2O . Insoluble in water and any solvent, non-toxic, odorless, chemically stable, does not react with any substance except alkali, hydrofluoric acid. Various types of silica because of the way they are formed of different porous structures. Silicone cover Dongguan City Hengli Hang Yawei printing equipment RTV silicone materials firm its packaging can be divided into single-component and two-component RTV silicone curing mechanism can be divided according to condensation forming and processing. Therefore silicone production, according to RTV silicone composition, curing mechanism and the use of technology can be divided into three types of silicone products factory in Dongguan, that is a single-component RTV silicone, two-component condensation-type RTV silicone and two-component molding plus room vulcanized silicone. These three series of RTV silicone has its own characteristics: the advantages of single-component RTV silicone is easy to use, but deep curing speed is more difficult; the advantages of two-component RTV silicone curing silicone that hold heat shrinkage small, non-swelling, no internal stress, curing can be carried out simultaneously inside and surface, deep cure; addition-curing RTV silicone time depends mainly on temperature, and therefore, can be controlled by temperature adjustment cure rate. Silicone mold factory, constant Yawei printing equipment (certified), silica gel provided by the Dongguan City Hengli Hang Yawei printing equipment materials firm. Dongguan Heng Li Heng Yawei printing equipment materials firm (dghyw88.1688.com) is Dongguan, plate making, printing supplies leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
