Coatings used in the pigment is mainly divided into inorganic and organic pigmentstwo, although with the environmental protection requirements continue to increase,organic pigment to occupy more market share than the original, but the non-polarpigments with its cheap price, high covering power, dominant light good weatherabilitystill occupy half of the country market with pigment.
Inorganic pigment is made from natural mineral or inorganic compounds of iron oxide pigments pigments, which is second only to titanium dioxide inorganic syntheticpigment production in the world of second important products. Iron oxide pigmentchromatography is complete, commonly used color has yellow iron oxide, black brown,Tie Hong, iron etc.. At the same time, it has the advantage of low price, good durabilityand high covering power, the use of building coating is very suitable for therequirements of color brightness is not too high.
In recent years, with the environmental protection issues more and more attention from all walks of life, using a variety of iron containing waste, as well as the production of titanium dioxide by-product ferrous sulfate iron series pigments extracted frommanufacturing more show incomparable advantages.
China is an important origin of inorganic pigments of primary goods, with iron oxide pigments on the world of domestic consumer market rate reached 38%. With the development of private enterprises in production and product quality continues to improve, China is expected to become the world manufacturing center of inorganicpigments in the near future.
