Nano Calcium Carbonate , Nano Precipitated Calcium Carbonate , Nano CaCO3 NCC-112 for solvent based paint
Application of Nano Calcium Carbonate NCC-112:
Nano calcium carbonate NCC-112 is used for solvent based paint.
Features of Nano Calcium Carbonate NCC-112:
Nanometer calcium carbonate NCC-112 is a pigment filler in the paint industry. It has the advantages of fine, uniform, high whiteness and good optical performance. The nano-sized superfine calcium carbonate has the steric hindrance effect. In the paint, can make the formulation medium density of the high density lithopone suspension, the anti - deposition effect. Used in the paint, the paint film whiteness increases, the gloss is high, while the hiding power is not reduced, mainly used in high-grade car paint.
Manufacturing methods of Nano Calcium Carbonate NCC-112:
Industrial preparation of nanometer calcium carbonate by carbonization method, soluble in water, will be good quality calcium oxide and the generated suspended calcium hydroxide and crushed under high shear force, multistage solid-liquid separation to remove particles and impurities, have a certain concentration of purified calcium hydroxide slurry. In a certain concentration and purity of Ca(OH)2, the suspension of a high purity carbon dioxide gas is carbonized. The nucleation rate of calcium carbonate was controlled by the parameters such as temperature, pH value and the flow rate of carbon dioxide gas. After the formation of a certain crystal nucleus, the crystal nucleus formation control is transformed into crystal growth control. At this time, the growth rate of each crystal surface is controlled by adding the crystal regulator, so that the morphology can be controlled. Continue carbonization to the end point, add dispersants to regulate the particle surface charge, and get the dispersed cubic calcium carbonate nanoparticles. The obtained nanometer calcium carbonate particles can be controlled by 25 ~ 60nm, and the square is about 25m2/g on the surface, the oil absorption value is less than 30g/100gCaCO3, and there is no agglomeration. The product has excellent performance and can be used as functional filler in solvent paint and automotive primer.
