It can be dissolved by NaOH, HF.Other sorts of acid, drinking water and solvents can’t dissolve the solution. Resistance to large temperature, no combustion, excellent insulation, odourless houses
1. White Carbon Black (Silicon DioXiHu (West Lake) Dis.de, Hydrated Silica) are a versatile inorganic chemical which are utilised for reinforcement of rubbers and plastics, coating and paints, printing inks and cosmetics, antiblocking of plastic foils, cost-free operating and free flow of sticky sound and liquid substances, carrier for pesticides, pesticides, substantial temperature insulation, stabilizing of beer and silicon rubber.
two. White Carbon Black (Silicon DioXiHu (West Lake) Dis.de, Hydrated Silica) possesses a higher reinforcing possible and imparts to rubber compounds notably higher Shore hardness, tensile toughness, tear resistance and abrasion resistance. In orEPTto obtain optimum rubber-technical information the addition of activators like glycols, amines or other alkaline accelerators is necessary.
Fumed silica powEPT(Fumed silica powder)
Fumed Silica is produced with the technique of gas section . Its concept is burning the chloride unEPToxyhydrogen flame and substantial- temperature vapor stage hydrolysis, and collected concluded product after refining approach of condensation, separation, deacidification and screening.
