Uses:
1. Rubber Industry:
Nanometer calcium carbonate with ultra-fine, ultra-pure characteristics of the production process to effectively control the crystal shape and particle size, but also carried out surface modification. Hence its in rubber with a three-dimensional structure of space, and good dispersion characteristics, can improve the material reinforcing effect. Such as the chain-like nano-calcium carbonate, in the rubber mixing, the chain-like chain was interrupted, will form a large number of high-activity or high activity of the surface points, they form a bond with the rubber long-chain link, not only a good dispersion, and significantly increased the reinforcing effect. In Japan, the rubber industry, the small oil seal, auto parts, ranging from tires, tape, rubber hose have been widely used in nano-calcium carbonate, is more noteworthy is that it not only as a reinforcing filler used alone, but also according to production used in conjunction with other fillers, such as: carbon black, silica, light or heavy calcium carbonate, clay, titanium dioxide, etc., to reinforcing, filling, mix colors, improve processing technology and product performance, and reduce the rate of containing plastic or in part, instead of white carbon black, titanium dioxide and other expensive white fillers purposes.
2. Plastic Industry:
As the nano-calcium carbonate with a high gloss, wear rate is low, surface modification and thinning oil and other characteristics, can be filled in PVC, polypropylene, and phenolics such as polymers, are now widely used in PVC cable filler in.
3. Coatings Industry:
Can be used as paint filler, with a delicate, uniform, white high, and good optical performance, nanometer calcium carbonate with the steric effect, in the paints, the formula allows a greater density of lithopone suspension, since anti - sedimentation. Paints, the film whiteness increase, high gloss, while the hiding power is not reduced, this performance makes it a lot in the paint industry has been replicated elsewhere.
