The surface coloring method of the Embossed Decorative Tiles of the clear water wall refers to the surface of the product during the production process or the burned product. The Sintered brick is buried in the processing place or specially attached with decorative effect surface, in order to increase the added value of the product, enhance the market competition ability of the product, or to reduce the construction cost (no need to paint the wall Paste the outer material, etc., beautify the appearance of the building, improve the durability of masonry.
Commonly used methods can be divided into three categories: that is, through the addition of pigment, or change the ingredients, or change the roasting method,Embossed Decorative Tiles so that the surface of the product coloring; sintered Bricks Secondly, after the sludge extrusion, in the mud table and processing, so that the product surface showing a different texture or color; the last category is grinding on the burnt product, the resin is soaked, Water immersion and other methods, these three types of methods are summarized as follows:
There are many ways to color the brick body, mainly the following:
① integral coloring method. Usually the bricks are burned in the oxidizing atmosphere after the color of different shades of the red system. such as in the raw materials and other coloring of the mineral material can be the whole of the brick (from the inside to the outside) color changes to achieve a better decorative effect of the purpose. These mineral raw materials, most of which are industrial wastes or inexpensive materials with a price, such as manganese ore or manganese slag (can produce brown effect),Embossed Decorative Tiles as well as steel plant dust (including Fe20, waste in about 50%, can produce deep red to black red effect), sintered brick some pesticide factory waste and other metallurgical industry waste, etc. The whole coloring method is also the product of adding human lime powder in low iron clay to turn yellow hue.
② apply makeup to the soil. The makeup soil is mainly composed of a specific adhesive, flux, filler and coloring agent. Sometimes in the make-up of the soil plus organic materials as a binder, in order to enhance the make-up of the soil and the surface layer of the joint ability of the body. The prepared soil is applied to a brick surface by spraying or pouring, dipping, etc., and the surface of a solid specific color is formed on the slab by roasting.
③ Glazing method. It is a special glaze suitable for the thermal expansion coefficient of the brick, which is applied on the bad surface of the bricks, and the sintered bricks form a glaze layer of a specific color through roasting on the brick surface.
④ surface staining method. The staining method is used to extract a few millimeters of the surface of a person with a certain coloring metal salt solution, and a solid layer of a specific color layer is formed on the surface after roasting. Because the brick itself is red tone,Embossed Decorative Tiles so this method of staining if the color range is small, only to show the deep color of the product surface, such as crimson, dark green, brown, black and so on. Moreover, the surface staining method has certain conditions, which relate to the composition of the raw materials, the compactness and uniformity of the billet body.
⑤ Surface Coating method. This method is sufficient in the process of extruding the mud strips of the body, extruding the prepared surface coloring mud evenly through a special device and attaching it to the surface of the body coat the hum of the coating is generally in the 5-10mm, by roasting the solid bonding layer with the bad body and presenting a specific color surface.
The method of applying color sand to the surface of ⑥ this method will mix the colorant and sand in advance, and add the human binder to make colored sand. The colored sand is sprayed into or pressed into the surface layer of the mud bar. Sintered bricks form a predetermined color of the sanding surface. If the hardness of the extruded mud bar is too high, can use the method of spraying steam or spray water mist,Embossed Decorative Tiles first soften the surface of the mud (only a few millimeters deep), ran the color sand spray person or pressed into the mud strip surface layer roasting after the color sand and the body surface layer formed a solid bonding layer. Using this method, the surface decoration effect of various tones can be produced. In addition,Embossed Decorative Tiles after the waste ceramics are broken, the method can be applied to the surface of the Adobe (Note: The above methods are best used for burning clean fuel, such as natural gas, gas, light diesel, etc.
⑦ Roasting Coloring method. This method can change the atmosphere in the kiln at the time of roasting, and the coloring agent in the billet will show a different color method. such as in the atmosphere of reduction, sintered bricks fired green bricks. Now, using gas or large-yi as fuel in the tunnel kiln, the technology of roasting in the reduction atmosphere has been successfully used in West Ouchi for more than 10 years.
