Inorganic color pigments, iron oxide pigments, a large quantity of surface, use is very extensive too. The use of a large number of building materials, paint, printing ink, torubber, plastics, ceramics, glass products. Because iron oxide pigment with excellentpigment connectivity, has high chemical stability and physical resistance fastness.
With the rapid development of China's building materials industry, in recent years, the color cement brick, floor tile, wall tile, color color color color concrete tile ratio andpavement of new building materials are widely used in all kinds of buildings, squares,roads and municipal construction engineering, which plays an important role inbeautifying the urban environment. In the new materials that blew in, iron oxide pigment with excellent tinting application performance, at the same time with absorbingultraviolet and received protection censure base material used in system occurs in thedegradation and advantages of low price, by the color building materialsmanufacturers favor.
Iron oxide pigment mainly has the following characteristics:
1 good dispersibility
Lightfastness and weatherability of 2 excellent
3 acid
4 water resistance
5 solvent resistance
6 resistant to other chemicals
7 alkali resistance
8 good coloring, no color bleeding, no migration
The domestic color cement tile currently has homogeneous color cement tile andsurface layer of two kinds of color cement tile. The color of water along the tile of Europe and the United States are homogeneous tile, color processing using hybrid.Pigment into the overall texture tiles, naturalness, color Matt soft some spray on thesurface of homogeneity tile again on the coating. Homogeneous color cement tile withlarge and colorful surface color layer. Domestic encaustic tile production line is used for the majority of feeding, stirring, roll forming, cutting process of coloring treatment,curing, demoulding, packing and so on, in the production equipment is the introduction of foreign automatic production line with domestic semi automaticproduction line, cast iron and aluminum zinc alloy foil mould made of steel sheet.Variable type of thin steel plate, cast iron is too heavy, the few aluminum zinc alloy foildie, but the one-time investment is large, so the quality of domestic Caiwa uneven,encaustic tile coloring pigment with an inorganic pigment cheaper mainly. Of course,all kinds of iron oxide pigments is firstly used. China tile industry since developed 90 time initial stage, belongs to a new industry, with people's life improved, encaustic tilewill develop from the surface coating of iron oxide pigments into homogeneous tiles,demand will greatly increase. Color cement tile and color cement tile, is also divided into two homogeneous and surface color layer. There are not many domestic production of homogeneous color brick factory, the vast majority of using colorsurface layer brick mold steel mold and plastic two, the requirements of its production process and use of iron oxide pigments are like color cement tile technology.Technique of pavement color in-situ cement is used in cement pavement pouringordinary along the wet revolutionary situation, i.e., on the road to sprinkle a thin layer of color cement layer, then with the help of pavement patterns with press out pattern,when the surface after drying spray a layer of resin, instant and the road lights up.
The requirements of the construction of this cast of iron oxide pigment pavementperformance applications, requirements like colored cement tile with iron oxide pigment technology. Iron oxide pigment and its colorful pigment is the major colorantcolor cement, because iron oxide pigments have to pull folding pressure affect the strength of cement is very few, the color is bright, the relatively low price, so thecement because after grinding after the color is consistent, and provides convenience for application of concrete and mortar industry products.
Water paint is mainly used for concrete and mortar product coloring and water-based paint coloring. Foreign construction industry for the sake of convenience, the iron oxide pigments in coagulation ingredients, with building application to the development of convenient, efficient, high quality, low price trend demand, iron oxide pigment water paint will be more and more into the building materials market.
