Industrial grade white carbon black

Silica is a general term for white powdered X-ray amorphous silicic acid and silicate products. It mainly refers to precipitated silica, fumed silica, ultrafine silica gel, and also includes powdered synthetic silicic acid. Aluminum and calcium silicate. Silica is a porous substance whose composition can be represented by SiO2·nH2O, wherein nH2O exists in the form of a surface hydroxyl group. Soluble in caustic and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustible, odorless, odorless, and has good electrical insulation.
White carbon black Chinese alias: white carbon black (combustion method); gas phase white carbon black; granulated white carbon black; pharmaceutical grade white carbon black; GH-7 type white carbon black; GH-1A type white carbon black; -1B type white carbon black; hydrated silica; white carbon black; white smoke; precipitated hydrated silica; pure latex; colloidal silica; precipitated silica
product application: due to a series of advantages of silica products So that it can be widely used in many fields.
Applications in the field of optics Nanoparticles are used in infrared reflective materials primarily for film and multilayer films. Nanoparticle film materials have good application prospects in the bulb industry. High-pressure sodium lamps and various iodine arc lamps used for photographing and photography require strong illumination, but 69% of the energy is converted into infrared rays when the filament is heated. This indicates that a considerable amount of electrical energy is converted into heat and is consumed, only a small amount. Part of the conversion to light energy to illuminate, at the same time, the heat of the lamp will also affect the life of the lamp, how to improve the luminous efficiency, increase the illumination has been a key issue to be solved urgently. The birth of nanoparticles has provided a new way to solve this problem. Since the 1980s, researchers and technicians have used nano-SiXX and nano-TiO2 particles to make multilayer interference films with a total thickness of micron, which is lined on the inner wall of the bulb cover. The result is not only good transmittance, but also strong infrared reflection ability. . According to experts measuring the same kind of lighting brightness, this kind of luminaire can save 15% of energy compared with traditional halogen lamps.
