Description

A preparation method of wall decorative bricks for regulating space humidity

technical field

The invention provides materials in the construction field, in particular a method for preparing wall decorative bricks for adjusting space humidity.

Background technique

In reality, the tiles used for wall decoration are usually glazed, which can only have an aesthetic effect and has no functionality, that is to say, it cannot exchange with the water vapor in the space, so it has no effect on regulating the humidity of the space.

For specific occasions, the automatic adjustment of space humidity is required to meet the humidity requirements, such as: environmental spaces requiring humidity, plant cultivation rooms, greenhouses and animal farms. All require the environmental space to have a specific humidity to meet the needs of the environmental conditions.

Contents of the invention

In order to automatically adjust the humidity of the environment space, the invention provides a method for preparing wall decorative bricks for adjusting the humidity of the space. The method solves the technical problem of automatic adjustment of water vapor of the decorative brick through the material selection of the decorative brick and the porous setting.

In 100 parts of raw materials, there are 60 parts of diatomite, 10 parts of glass microspheres, 10 parts of cement, 10 parts of sodium metasilicate, and 10 parts of bentonite, and the parts are parts by mass.

The raw materials were pulverized to 200 mesh respectively.

Combine ingredients and stir well.

In 100 parts of raw materials, add 30-40 parts of water, stir and mix evenly to become tire mud.

suppress:

Put the quantitative tire mud into the mold cavity of the press, apply pressure, hold the pressure for 2 minutes after pressing, and then eject the carcass from the mold and demould.

drying:

Put the demoulded carcass on the drying rack and push it into the drying chamber for drying.

sintering:

Put the dried carcass on the sintering formwork, push the formwork into the sintering kiln, sinter at 800-850°C for 1 hour, then stop heating, cool to room temperature naturally, and take out the sintered decoration brick.

Backing plates 01 are placed layer by layer on the drying frame and sintering formwork, and a plurality of through holes 02 are distributed on the backing plate, and supporting legs 03 are respectively provided at four corners of the opposite lower side of the backing plate.

The pressing adopts a hydraulic machine, and a pressure rod 2 is installed in the pressure oil cylinder 1, and the pressure rod is connected with the tire plate 3, and is fixedly connected with the upper mold 5 through the upper mold fixing screw 4 on the tire plate, and a mold 6 is arranged at the lower part of the upper mold. A mold cavity 7 is provided in the mold, and a lower formwork 10 is fixed on the hydraulic press base plate 11 at the bottom of the die cavity, and a jacking rod 12 is worn between the hydraulic press base plate and the lower template, and the jacking rod is installed in a jacking cylinder 13. The top plate 8 of the mold cavity bottom is fixed on the jacking rod by the top plate fixing screw 9 .

making process:

Mix the raw materials and add water to make them into mud, weigh them and add them to the mold, press down the pressure rod to compact the raw materials in the mold cavity, when the set pressure is reached, lift the pressure rod, lift the upper mold, Then start the jacking cylinder to make the jacking rod lift the top plate, lift the pressed decorative brick body to the upper part of the mould, lift the mold horizontally, then put the green body on the backing plate of the drying rack, place the backing plate and The green body, together with the green body and the drying rack, is pushed into the drying chamber for drying treatment.

The dried decorative brick body drying rack is used as a sintering formwork, and is pushed into the sintering kiln by rollers on the rails for sintering. The sintering temperature is controlled between 800-850°C.

After the sintering is completed, it is naturally cooled, and when it is cooled to room temperature, it is pushed out from the sintering kiln together with the sintering formwork, and the decorative brick is removed from the sintering formwork as a finished product.

The technical principle of the backing plate:

There are through holes on the backing plate. When the decorative brick body is placed on the backing plate, the heat energy is conducted and convected upward from the legs, and the heat is transferred to the decorative brick body through the through holes, so that the decorative brick body is dried or sintered.

Comparative analysis with existing technologies:

The existing decorative bricks made of clay need to be glazed after sintering. The glazed decorative bricks are isolated from water and have no through holes, so they do not have water absorption and adsorption, so they have no positive impact on the environment and can only be used as decorations. brick used.

The raw materials used in the present invention are different from the prior art, especially diatomite and glass microspheres are used as main materials, and the sintered decorative brick has porosity, so it has water absorption and adsorption. The characteristic is that the raw materials used are different from the prior art, have obvious technical features, and have creativity and novelty, specifically, the present invention is different from the raw materials used in the prior art.

The composition of the backing plate has through-holes on the backing plate and legs on the bottom, and can be used in layers. It can be used not only as a drying rack, but also as a sintering mold base, so that one board can be used for multiple purposes. This backing plate is in the prior art. No one has adopted it, so it is creative.

The hydraulic press presses the adobe body of the decorative brick, and the adobe body of the decorative brick is pressed down through the press with the upper pressing mold. After pressing, the adobe body of the decorative brick is lifted by the lifting mechanism, removed from the mold, and then dried and sintered. The pressing mold of the present invention is different from the prior art, and also has creativity.

To sum up, the raw material formula, backing board composition and pressing method of the present invention are quite different from the prior art.

Features:

Diatomaceous earth and glass microspheres are used in the raw materials, which have porosity and adsorption. Among them, cement, sodium metasilicate and bentonite play a bonding role, which can improve the cohesiveness of the decorative brick body during the pressing process, and increase Strength for easy mobile operation.

The decorative brick body is pressed and formed by a hydraulic mechanism, which has the advantages of accurate positioning, fast pressing speed, balanced pressure and stable quality.

The decorative bricks made are microporous and have strong water absorption. Tests have shown that the water absorption rate can reach more than 50%, and they are also absorbent.

Due to the strong water absorption of the decorative bricks prepared by the method of the present invention, when the water vapor in the environmental space is too large, the decorative bricks absorb water, and when the environmental space is dry, the decorative bricks release water vapor, increasing the humidity of the environmental space, thus producing water vapor balance and automatic adjustment role.

Because the decorative brick has the function of balancing water vapor, it also has adsorption properties, can absorb harmful gases in the environmental space, and convert them into carbon dioxide, so it has the effect of purifying the air.

The decorative brick of the present invention can be used as an attached decoration on the wall of an indoor environment space, and is especially suitable for use in toilets and TV background walls.
