Nano calcium carbonate

Uses: 1. Rubber industry: Nanometer calcium carbonate with ultra-fine, ultra-pure characteristics of the production process to effectively control the size of the crystal shape and size, but a surface modification.

Therefore, in the rubber with a three-dimensional structure of space, and good dispersion characteristics, can be reinforced to enhance the role of materials.

Such as chain-like nano-calcium carbonate, in the rubber mixing, the chain-like chain to be interrupted, would form a large number of high-activity or high activity at the surface, they form a long chain and rubber key link, not only a good dispersion, and significantly increase the role of the reinforcement.

Rubber Industries in Japan, the small oil seal, auto parts, large tires, tape, rubber hose have been widely used in nano-calcium carbonate, even more noteworthy is that it not only can be used alone as a reinforcing filler, and can be production used in conjunction with other fillers, such as: carbon black, fumed silica, light or heavy calcium carbonate, clay, titanium dioxide, etc., to reinforcing, filling, color, processing technology and products to improve performance and reduce the rate of containing plastic or partial replacement of silica, titanium dioxide, such as the high cost of the purpose of the white filler.

2. Plastics Industry: As the nano-calcium carbonate has a high gloss, low wear rate, surface modification and thinning oil etc., can be filled in PVC, polypropylene, and polymers such as Bakelite, and now it is widely used in PVC cable fill in. 3.

The coatings industry: Can be used as paint filler, with fine, uniform, high brightness, and good optical properties, nano-calcium carbonate with steric effects of the paints to make this recipe in a larger density of suspended lithopone, since anti - sedimentation.

Paints, the paint film to increase brightness, high gloss, and the hiding power is not reduced, the performance of the coatings industry has been its role in a large number of promotion.
