Special activated calcium carbonate for ink

The special active calcium carbonate of ink is used as a high grade filling agent. It is widely used in rubber, plastic, plastic steel doors and windows, PVC cable materials, advanced coatings, pipes, tires, sole, polyethylene blowing film, sealant strips, fiberglass products, cable wrapper, paper, building materials, ink, daily chemical, textile and feed. Food additives and other industries. As a filler in the coating, it can play a skeleton role, so it is called "physical pigment". In the oil coating, the filling amount can reach 10-50%, and the filling amount in water-based coatings can reach 10-20%.
The active calcium carbonate used for printing ink is based on the active calcium carbonate, and the surface of the inorganic powder is modified by using the multifunctional surface active agent and the compound efficient processing auxiliary. The modified calcium carbonate powder has a special cladding structure on the surface, which can significantly improve the dispersion and affinity in polyolefin and other polymer matrix, and can produce interfacial action with the polymer matrix, thus improving the impact strength of the products. It is a kind of excellent incremental filling additive. The amount of filling is generally 30-100%, and some products even more than 100.
Characteristic：
1) appearance: white powder, non-toxic, tasteless, non irritating, non combustible, non explosive, low refractive index, easy coloring, insoluble in water and stable in air.
2) after the product was activated, the molecular structure and particle size distribution of the product were uniform, showing strong hydrophobicity.
3) it has the characteristics of high whiteness, good fluidity, good gloss, uniform dispersion and large amount of filling. It also has excellent lubricity, fluidity, dispersivity and organic properties.
4) the intermolecular affinity between rubber and plastics is strong, and the volume of filling is more than 2-5 times to that of ordinary calcium carbonate, and the comprehensive production cost is obviously reduced.
5) low oil absorption, high whiteness, high elongation, and its unique super strong metal stripping and significant lubrication effect can improve the brightness of the surface of the products, wear and impact strength.
6) it can reduce attrition degree of processing machinery, improve product processing technology, improve product performance, and has better reinforcing effect.
7) the product is applied to the advanced coating, which can improve the solid filling and reduce the viscosity, at the same time endow the coating with wear resistance, corrosion resistance, reduce the baking temperature, shorten the baking time, improve the quality of the product, reduce the production cost, and have obvious economic benefits.
