The invention relates to a production process of pigment carbon black used for film spraying, comprising the following steps: performing air filtration and preheating; mixed combustion of air and gas; reaction of raw materials and additives; quenching of quenching water; separation of carbon black smoke. The selection of raw materials is relatively easy and the price is low. Combined with the air-oil ratio and output, it can meet continuous production and the quality of carbon black is stable; using coal gas as fuel, it still has a price advantage over natural gas and washing oil after treatment; using deionized water quenching Extinguishing reaction can not only generate steam to activate carbon black, but also reduce impurities in carbon black; use multi-stage raw material preheating device to better preheat raw materials, reduce viscosity, shorten raw material vaporization time, and essentially reduce water washing; Utilize the micron pulverizer to carry out ultra-fine pulverization to reduce water-washing impurities again; the invention produces pigment carbon black with low heavy metal content, high blackness, easy dispersion, low impurity and high purity.
Description
technical field [0001] The invention belongs to the technological field of pigment carbon black, and more specifically relates to a production process of pigment carbon black used for film spraying. Background technique [0002] Carbon black is mainly divided into carbon black for rubber and carbon black for non-rubber. According to the statistics of carbon black consumption in the world, carbon black for rubber accounts for 89.5% of the total, carbon black for non-rubber accounts for 10.5%, and carbon black for non-rubber mainly Including pigment carbon black, conductive carbon black, plastic carbon black, etc. Pigment carbon black is mainly used as black dye for color masterbatch, coating, paint, resin, etc. In fact, in different industries and fields, other index application requirements are put forward for pigment carbon black. The output of high-quality pigment carbon black in domestic carbon black enterprises is low, and the quality fluctuates greatly. There are many f...
