Watch Silicone Dongguan City Hengli Hang Yawei printing equipment inorganic silicone materials firm uses macroporous silica is generally used as a catalyst carrier, matting agents, toothpaste abrasive. So should choose different varieties for different purposes. Silica gel desiccant can be used for plating UV ink, and can be reused. Silica gel is silica gel mSiO2 · nH2O appropriate dehydration from the different particle size of the porous substance. Has an open porous structure, specific surface area (surface area per unit mass) is large, can absorb a lot of substance, is a good desiccant, adsorbent and catalyst supports. Silica gel adsorption is mainly physical adsorption, can be regenerated and used repeatedly. Silicone ring Dongguan City Hengli Hang Yawei printing equipment materials firm silicone products based on silicon - TPE ink oxygen (Si-O) bond main chain structure, C-C bond energy of 82.6 kcal / mol, bond Si-O bond energy of silicone 121 kcal / mole, the heat stability of the high ink silicone products, at high temperatures (or radiation) molecular bond is not broken, do not decompose. Silicone is not only high temperature, but also low temperature, can be used over a wide temperature range. Whether it is physical or chemical properties and mechanical properties, changes in temperature are very small.
