Embossed Decorative Tiles Forming A Conical Layer Of A Particular Color

Aug 07, 2017

(1) coloring method

There are many ways to color the Embossed Decorative Tiles, 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 Can produce dark red to black and red effect), some pesticide plant waste and other metallurgical waste industry, etc .; also in low iron clay clay lime powder to make it into a yellow tone of the product, are the overall color method.

② Apply makeup soil

Makeup 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 combination of the make-up soil and the surface layer of the body t Preparation of a good make-up soil with embarrassment or pouring, dip method applied to the brick Of the surface, 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 the coloring method of this color range is small,Embossed Decorative Tiles 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, 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,Embossed Decorative Tiles 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 to mix the colorant with the sand in advance, while adding the binder, making color sand, the color sand spray or pressure into the mud surface layer, 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), 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,Embossed Decorative Tiles it can be applied to the surface of the brick by this method

(Note: the above methods are best to use the following clean burning of fuel, such as natural gas, gas, light diesel, etc.).

⑦ roasting coloring method

This method is to change the atmosphere in the kiln during roasting, and the coloring agent carried in the green body presents a different color method, such as a brick which is 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:

① 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.

② 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 from the 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 of the surface cut, and exposed rough surface layer. As the green body contains more or less granular materials, in the continuous cut off the smooth surface layer,Embossed Decorative Tiles can be cut on the rough surface after the length of the scratches ranging from the rough surface to enhance the decorative effect.

③ hair surface method

Apply a rotating wire brush or a vibrating wire brush to the smooth surface of the mud on the smooth surface of the extruded mud.

④ sand method

This method is used in Nordic more, the main purpose is to imitate the ancient hand-formed sand brick, but the addition of sand is no coloring ordinary sand.

⑤ surface plus fuel, 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 powder, and then the two brick bar stack in a Muddy, fired after the formation of a similar pattern of embossing

(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.
