At present, calcium carbonate has been widely used in papermaking, plastic, plastic film, chemical fiber, rubber, coatings, adhesives, sealing agents, daily chemicals, cosmetics, building materials, paint, ink, oil gray, seal wax, putty, felt layer, felt layer, felt layer, felt layer, felt layer, felt layer, felt layer, felt layer, felt layer, felt layer, and felt layer. Packaging, medicine, food (such as gum, chocolate), and feed, their functions are: increase product volume, reduce costs, improve processing performance (such as regulating viscosity, flow change performance, vulcanization performance) Semi -strengthening, improving printing performance, and improving physical properties (such as heat resistance, lighting, abrasion resistance, flame retardant, whiteness, gloss), etc.
In the early days, some experts believed that due to the characteristics of low energy consumption, simple craftsmanship, and convenient production, some performance advantages, it can replace or even use in many uses. Beyond light calcium, and pointed out that the proportion of heavy calcium and light calcium (in fillers) in developed countries is 14-18: 1, and the demand for heavy calcium carbonate is far greater than that of light calcium carbonate. With the continuous micro -fineness of heavy calcium, the increasing variety of active heavy calcium, and the continuous deepening of application research, the scope of application of calcium carbonate will continue to expand, and the application amount will continue to increase.
Under such views, taking the application of calcium carbonate in papermaking and plastic as an example, experts analyzed that after promoting neutral gel in papermaking, due to the high oil absorption value of calcium carbonate, the value of light oil carbonate is high, and the value of light oil absorption is high, and The glue consumption is large and the gel effect is damaged, while the heavy calcium carbonate is vice versa. In addition, the light calcium carbonate is strong. If it is added to the paper, the paper strength is not as good as adding heavy ultra -fine calcium carbonate. In plastics, because of the high oil absorption value of ordinary light carbonate, adding it to some plastics is too light, it is difficult to mix in mixing, it is difficult to increase the amount. The development of industrial development, the development of plastic to high -functional and high value -added targets, the amount of general light carbonate may be reduced.
