Embossed Decorative Tiles Beautify The Appearance Of The Building To Improve The Durability Of Masonry

Sep 28, 2017

Embossed Decorative Tiles surface treatment method refers to the product in the production process or has been fired on the surface of the product, the processing or specifically attached to the decorative effect of the surface to enhance the added value of products and enhance the market Competitiveness, 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.

Common methods can be divided into three categories:

One is through the addition of pigment, or change the ingredients, or change the roasting method, so that the product surface coloring;

Followed by the mud in the extrusion, the surface of the mud in the processing, so that the product surface showing a different texture or color;

The last category is in the already fired products for 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:

① overall coloring method

Usually the brick in the oxidizing gas ammonia after firing are different levels of different red color. If you add other colorable mineral materials to the raw material, you can change the color of the brick as a whole (from inside to outside) to achieve a better decorative effect. (Such as manganese ore or manganese slag (which can produce brown effect); and if the steel dust (including Fe2O3 in about 50% of the waste,Embossed Decorative Tiles the use of waste materials, Can produce dark red to black and red effect), some pesticide plant waste and other metallurgical waste industry, etc .; also in low iron clay lime powder into lime powder into a product, etc., are the overall color method.

② Apply makeup soil

The make-up soil is mainly composed of specific clay, flux, filler and colorant. And sometimes add the organic material as a binder in the make-up soil to enhance the binding ability of the make-up soil and the surface layer of the green body. The make-up soil is applied to the brick Of the surface,Embossed Decorative Tiles after roasting in the body surface to form a solid specific color surface.

③ glaze method

A special glaze suitable for the thermal expansion coefficient of the brick is applied to the surface of the brick to form a tapered 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 surface of the formation of a strong layer of solid color. As the brick itself is red withered, so this coloring method of the smaller range of color, can only show the dark tone of the product surface, such as crimson, dark green, brown, black and so on. And this surface dyeing is a certain use of conditions, these conditions related to the composition of raw materials in the body, the density of the body and uniformity.

⑤ surface coating method. This method is in the blank body extrusion process,Embossed Decorative Tiles 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 this coating is generally 5 "lomm, after roasting with the body to form a solid bond layer and showing a specific color of the surface.

⑥ surface applied sand method

This method is in advance to mix the coloring agent and sand, while adding the binder, making color sand, the color sand spray or pressure on the surface of the mud surface, 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,Embossed Decorative Tiles the first softening of the surface of the mud (only a few millimeters deep), then the color sand spray or pressure on the surface layer of mud. 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, after the waste ceramic is broken, it can also be applied to the surface of the brick by this method

⑦ roasting coloring method

This method is to change the atmosphere in the furnace when firing, and the coloring agent carried in the green body presents a different color method, such as the brick in the reduced atmosphere. Now the use of gas or natural gas as a fuel in the tunnel kiln,Embossed Decorative Tiles in the reduction of the atmosphere of the technology in Western Europe has been successfully used for more than a decade.
