Introduction to common surface modifiers for calcium carbonate

Surface modification of calcium carbonate powder mainly addresses three issues: ① Dispersion of calcium carbonate; ② Interface bonding with organic polymer materials; ③ Functionalization and specialization after surface modification.

Research progress on nano calcium carbonate in RTV silicone rubber applications

Research progress on nano calcium carbonate in RTV silicone rubber applications. Room temperature vulcanizing silicone rubber is now widely used as adhesives, sealants, potting and molding materials, and has applications in various industries. Among them, reinforcing fillers have a very important influence on the rheological and mechanical properties of RTV silicone rubber. Nano calcium carbonate is characterized by its low price, excellent performance, large filling amount, non-toxicity and odorlessness, and can be widely used as a reinforcing filler for RTV silicone rubber.

The function of light calcium carbonate

Calcium carbonate is one of the earliest and most widely used fillers in the rubber industry. The large-scale addition of calcium carbonate to rubber increases the volume of the product, saving on expensive natural rubber and thus reducing costs. The addition of calcium carbonate to rubber results in higher tensile strength, wear resistance, and tear strength than pure rubber vulcanizates, and it exhibits a significant reinforcing effect in both natural and synthetic rubbers. It can also adjust viscosity.

What is the market outlook for calcium carbonate?

Calcium carbonate is a commonly used inorganic filler in industry, with wide applications. What are the market prospects for calcium carbonate? What equipment is used for ultrafine grinding of calcium carbonate? How fine can calcium carbonate be processed? Let's find out.
