Carbon black is divided into many kinds, such as pigment carbon black, special carbon black, white carbon black, etc. Among them, white carbon black is a special kind of carbon black, which is white in color and soft in texture, and is widely used in many fields.
Silica can be used as a reinforcing agent for rubber, and its reinforcing performance is even better than that of pigment carbon black after ultra-fine processing. It is more suitable for making light-colored rubber.
Silica can also be used as a thickener, which plays an important role in the blending of oils and paints. At the same time, it can also be used as a delustering agent for paint, a thixotropic agent for packaging materials of electronic components, a precipitating agent for phosphor powder when coating fluorescent screens, a filler for color printing rubber sheets, and a release agent for casting, etc.
After white carbon black is added to the resin, it can improve the moisture resistance and insulation performance of the resin. Filled in plastic products, it can increase anti-slip and oil resistance. Filled in silicone resin, it can be made into a plastic resistant to over 200°C.
Silica is used in the paper industry as a filler and as a surface ingredient for paper. It is also used as a carrier or dispersant for insecticides and pesticides, anti-caking agents, and liquid adsorbents and lubricants.
In general, white carbon black is a multifunctional carbon black type, which can emit light and heat in different fields.
