Embossed Decorative Tiles Clear water wall decorative brick surface treatment method refers to the product in the production process or has been fired on the surface of the product, the processing of fire specifically attached to the decorative effect of the surface to enhance the added value of products and enhance product market competition Capacity, or in order to reduce the cost of the building (no need to paint outside the wall, paste the outer material, etc.), beautify the appearance of the building to improve the durability of masonry. Commonly used methods can be divided into three categories: one is by adding pigment, or change the ingredients, or change the roasting method, so that the product surface coloring; followed by the mud after extrusion, the surface of the mud processing Product surface showing a different texture or color; the last one is in the firing of products on the grinding, impregnation resin, soaking and other methods, now these three types of methods outlined below:
(1) coloring method. There are many ways to color the brick body, mainly in the following categories: the overall coloring method. Usually the brick in the oxidizing atmosphere after firing are different levels of different red color. If you add other colorable mineral materials to the raw material,Embossed Decorative Tiles you can change the color of the brick as a whole (from inside to outside) to achieve a better decorative effect. The addition of these mineral raw materials, mostly industrial waste or unit price cheaper materials, such as manganese ore or manganese slag (can produce brown effect); also in the low iron-bearing clay by adding lime powder into a yellow hue Products, etc., are the overall coloring method. , Exacerbated soil. The make-up soil is mainly composed of specific clay, cosolvent, filler and colorant. Sometimes in the make-up soil to add organic material composition binder, in order to enhance the makeup soil and the body surface layer of the ability to combine. Preparation of a good make-up soil spray or pouring method, soaking method applied to the surface of the brick, after roasting and then the surface of the green body to form a solid surface of a specific color. Ƒ glaze method. A special glaze suitable for the thermal expansion coefficient of the brick is applied to the surface of the brick and fired into a glazed layer of a specific color on the surface of the brick. ④ surface staining method. Surface coloring method refers to the use of some colorable metal salt solution immersed in the brick surface a few millimeters deep, after the roasting surface to form a strong layer of specific color. As the brick itself is red, so the coloring method of this color range is small,Embossed Decorative Tiles can only show the dark color of the product surface, such as crimson, dark green, brown, black and so on. And this surface dyeing method has a certain conditions of use, these conditions related to the composition of the raw material in the green body, the density of the body and uniformity. ⑤ surface coating method. This method is in the blank body extrusion process, the preparation of a good surface of the colored mud material evenly through a special device extrusion and attached to the body surface. The thickness of the coating is generally in the range of 5 to 10 mm, and after firing it forms a strong bond layer with the green body and exhibits a specific color. ⑥ surface applied sand method. This method is to mix the colorant with the sand in advance, while adding the binder, making color sand, the color sand into or into the mud surface layer,Embossed Decorative Tiles forming a predetermined color of the sand surface. If the hardness of the extruded mud is too high, you can use spray steam or spray mist method, first soften the surface of the mud (only a few millimeters deep), and then sprayed into the sand or pressed into the mud surface layer. After the roasting sand and green body surface layer to form a solid layer. Using this method, you can create a variety of colors of the surface decoration effect. In addition, the waste ceramic can be used after this method can be applied to the surface of the brick (Note: The above methods are best to use the following clean burning of fuel, such as natural gas, gas, light diesel oil) ⑦ roasting coloring law. This method is to change the atmosphere in the kiln when fired, and the coloring agent carried in the green body presents a different color method, such as a brick fired in a reducing atmosphere. Now the use of gas or natural gas as a fuel in the tunnel kiln, in the reduction atmosphere of the technology in Western Europe has been successfully used for more than a decade.
(2) mud surface treatment methods. This method is to squeeze out the smooth surface of the mud processed into a decorative effect with a certain pattern, style, etc., the main methods are: roll method. Rolling method is to have a special pattern and texture of the rotating roller, the surface of the extruded mud out of the pattern or texture structure. The pattern of such rollers can be varied, such as various points, striped pits, bark-like wrinkles, and so on. , Peeling method. Extrusion of the smooth surface of the mud is sometimes used in some occasions, the effect is not as rough as the use of the effect. Another smooth surface of the mud on some defects (such as dry room whitening layer, fingerprint indentation, etc.) is not as rough as the degree of cover, so the extrusion of the mud with a wire or a special cutting knife will be smooth mud The surface is cut while exposed to the rough surface layer. As the green body contains more or less granular materials, in the continuous cut off the smooth surface layer, can be cut on the rough surface after the length of the scratches ranging from the rough surface to enhance the decorative effect. elongated surface method. On the smooth surface of the extruded mud, use a rotating wire brush or a vibrating wire brush to trim the smooth surface of the mud. ④ plus Han law. This method is used in Nordic more, the main wooden point is to imitate the ancient hand-formed sand brick, but the addition of sand is no coloring ordinary brick. ⑤ surface plus fuel,Embossed Decorative Tiles manufacturing embossing method. This method is used in the United Kingdom, northern Europe, the United States and so on, by squeezing the upper part of the extruded mud with pulverized coal, charcoal and other combustible fine powder, Together, after the formation of a rough pattern of embossed (Note: this embossing on the performance of finished brick without any adverse effects), masonry out of the wall to form a special effect. ⑥ chisel hair method. This method is the use of high-speed rotation of the surface with a lump-like belt machine, or pneumatic cutting hair machine, the mud surface chiseled rugged, rock-like surface, this method can also be with the peeling, Softening and other methods used in combination.
(3) finished brick surface treatment methods. This treatment methods are: surface grinding. This method was originally used to polish the brick surface of the building, so that brick masonry gray stalls smaller, in order to improve the thermal insulation properties of the wall. This method is very similar to the use of ancient buildings in China, "grinding to the seam" method, but the ancient hand grinding into a mechanical grinding. Now this method has also developed to the surface of the grinding brick, so that the brick surface outward appearance presents a special effect, such as some foreign residential indoor water wall, this grinding can be the surface of the body Roasted during the formation of the surface of the whitening layer (insoluble in water) material polished,Embossed Decorative Tiles so that the color of the brick body more uniform. , Frosted. The sandblasting of the brick surface, like steel rust, can treat the ugly color surface into a high-grade product with a rough surface. The above-mentioned whitening material can be polished by sandblasting, thereby eliminating roughening of the whitening layer and more uniform in the color of the masonry. This sandblasting treatment can be carried out in the factory, but also in the construction site to build a good masonry surface. soaking treatment. The main purpose of the water treatment is to eliminate the cracking of the lime particles in the brick body and to destroy the structure of the brick surface. This method should be carried out immediately when the brick is out of the kiln. ④ impregnated resin method. Impregnated resin refers to the possibility of pan cream will be covered with water glass decorative brick impregnated with silicone resin to plug the walls of the pores, not to enter the brick into the water, effectively prevent the pan frost. After the silicone impregnated brick, its strength will increase.
