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.

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.

Color identification method of iron oxide red:

The first category: visual method

Chinese has yet to develop national standards. Foreign standards ASTMD1535-95a,using the Munsell color label to represent the pigment color. Method does not providethe sample slurry preparation method, refer to ASTM standards of other pulping aftertest.

Second class: instrument test method

The use of the instrument directly measured pigment color value. Apparatus in accordance with this kind of method of color measurement instrument, color meter,colorimeter etc..

Determination of pigment color (dry powder and paste), cake and preparation of membrane way see section fourth of the two - white degree.

At present, iron oxide red mainly is divided into two kinds, one kind is the colorcomparison method, namely with the reference sample or instrument test results are given visual comparison; another kind is the direct method of the color measurement,or like number that the use of instruments or visual directly gives the amount of color.Mainly according to the testing method can know iron oxide red color values are consistent with the formulation of national standards for production of culture,provides important reference basis for the purchase of the iron oxide red or determine the quality level of iron oxide red.

Use:

Red iron oxide in the building materials industry is mainly used in cement color, color cement brick, colored cement tile, glazed tile, floor tile, imitation of concrete mortar,color color asphalt, terrazzo, mosaic tiles, artificial marble and stucco walls; in thepaint industry in the main to be used to manufacture all kinds of paint, paint, ink. In other industries, such as ceramics, rubber, plastics, leather wipe light paste used ascoloring agents and fillers. Widely used in building, rubber, plastic, paint and other industries, especially iron red primer with antirust function, can replace the expensivered lead paint, saving non-ferrous metals.

There are a lot of, iron oxides like iron oxide, FeO, magnetite and so on, I will introduce today is how to let the iron oxides to change as a pigment, the protagonist isiron, after a period of reaction into iron oxide yellow after.

Sulfuric acid and iron filings reaction of ferrous sulfate, sodium hydroxide is added into the air oxidation and preparation of crystal nucleus, plus ferrous sulfate and iron filings in the nucleus in suspension, heating drum into the air oxidation, pressure filtration, rinsing, drying, crushing the prepared iron oxide yellow. The reaction conditions: 74g iron adding 1000ml 15% sulfuric acid reaction to iron disappear,creating concentration is about 200g/L of ferrous sulfate. Add enough 30% ferrous sulfate solution to the above prepared in sodium hydroxide, stirring. A total of 40%iron into ferrous hydroxide [Fe (OH) 2], in 30 ~ 35 DEG C through the air, so that theoxidation of Fe to Fe nuclei formation. To scrap treatment which accession to the 90g/L, to generate 7g/L nuclei and 40g/L of ferrous sulfate, continue heating up to 85 DEG C, at a speed of drum air oxidation of 64H 600L/h, then filtering, washing, drying,pulverizing system containing iron oxide yellow.

Aniline method of iron oxide can be obtained at the same time two products, the cost is relatively low, but to take into account technological conditions of two products. Ironand one step oxidation method in the domestic not yet has the industrial scaleproducts, is a direction of the industry line. At present, a large number of domesticuse iron hydrolysis technology is more mature, low production cost, good product quality, but the iron law of low yield, long production cycle, iron slag on the pollution of the environment, but also a large area, so can not meet the current process. Shouldaccording to the situation of our country and create a more favorable view of process route, iron oxide red could waste resources of this feature using other industry, canthe extensive collection of ferrous sulfate by-product of titanium white. As the raw material of pickling waste liquor, aniline mud iron steel industry, mass production ofiron oxide red supply domestic and foreign market needs.

Inorganic pigment is divided into natural inorganic pigments and inorganic pigment,inorganic pigment is a natural mineral pigments. Organic pigments are coloured organic compounds, are also divided into natural and synthetic two categories. Nowcommonly used is a synthetic organic pigment coating technology: [according toChina ink network August 19th reports] inorganic pigment is non-ferrous metal oxides,metal or metal insoluble salt, inorganic pigment and divided into natural inorganicpigments and inorganic pigment, inorganic pigment is a natural mineral pigments.Organic pigments are coloured organic compounds, are also divided into natural and synthetic two categories. Now commonly used is a synthetic organic pigments, organic pigment color varieties, relatively complete, performance is better than inorganic pigment. Inorganic pigment is mainly of carbon black and iron, titanium, zinc, barium,cadmium, lead and other metal oxides or salts. Organic pigments can be divided intomonoazo, double azo phthalocyanine, lake, or fused ring pigments and other categories. Inorganic pigment fast, heat resistance, weather resistance, solvent resistance, hiding power strong, but not very complete chromatography, tinting strength is low, the color brightness difference, some metal oxides and salts toxicity.Diversity, organic pigment structure complete chromatogram, pure colors, strong coloring, but some products light resistance, weather resistance, solvent resistance is poor, high-grade organic pigments have light, good weather resistance, solvent resistance, but the price is expensive.
