Selection of tile repair colorants and their simple formulas. Tile repair coloring and glaze, the same as the coating of decorative architectural and sanitary ceramic products. It is closely integrated with the body of ceramic products, glaze, play a role in decorating and beautifying the building sanitary ceramic products, so that the products form a colorful ceramic world.

Now the development of the ceramic industry has entered a new era of color glaze, sanitary ceramic products decorative more and more inclined to directly use a variety of color glaze, to create a wide range of new series to meet the different needs of the domestic And foreign markets.

The method of preparing color pigment for ceramic blanks includes the following steps:

 (1) sieving the color pigment through a 325 mesh fineness screen;

(2) weighing the appropriate amount of color pigment and 3-5 times the color pigment of water to dilute into a color slurry in proportion to the color pigment, and then passing the color slurry through a 200 mesh sieve for a second time to be sifted;

(3) pouring the sifted color slurry into stainless steel and stirring it for 10 hours, to form an ultra-fine powdery slurry, which is ready to be sprayed. Ceramic blanks with color material preparation method using ultra-fine color powder directly diluted with water wet method, avoiding the traditional ceramic blanks with color material directly ball milling method, can be eliminated to wash change the color material of the brick will appear when the ball, resulting in a large amount of waste, time inefficiency, but also on the cesspool of the environmental protection of a greater pressure. The new method is fast, accurate, cost saving, reduce environmental pressure, adapt to the rapid production mode, especially suitable for wear-resistant bricks and through-body antique brick preparation.

Therefore, mastering the use of colorants in ceramic glaze technology is of great significance for improving product grade and enriching the variety and types of products of enterprises. The pigment issue is actually a fringe science, which involves other related disciplines, such as color science, ceramic physical chemistry and technology. The choice of tile repair colorants has a great relationship with the use of technology, which directly affects the quality of the product and the economic benefits of the enterprise.

In the past, the name of tile repair coloring material generally refers to the entire color raw materials used in ceramic decoration (including high temperature and low temperature), covering a wide range; and the so-called color pigment, refers to the pigment used for the decoration of ceramic products used only for low-temperature firing, but due to the color pigment in the glaze, easy to cause the dissolution of metal compounds in the color pigment; glaze coloring technology between the glaze coloring and the underglaze coloring (firing temperature of 1100-1200 (firing temperature 1100-1200 degrees). In the middle of the glaze layer, but the type of coloring agent used is also limited; color-forming porcelain tires using coloring agents mixed into the blanks, so that the product porcelain effect is excellent, the surface of the porcelain tires are generally covered with a transparent glaze; color glaze is the coloring agent and pigment introduced directly into the glaze, so that the glaze to form a color glaze (firing temperature of 1150-1280 degrees Celsius); there is also a method of coloring agent added to the insoluble kaolin clay, to make a ceramic coat (also known as cosmetic clay), the Used for the decoration of ceramic products, known as color makeup clay. However, it is still necessary to apply a layer of transparent glaze (firing temperature 1150-1250 degrees) on the surface of the pigmented make-up clay to increase protection and brightness. The color tones form a hazy beauty, but the types of colorants used are also limited.

It is only a tile repair colorant. However, in ceramic academia and most companies, both colorants and pigments, the names of the two have been used interchangeably, staggered without hindrance.
