The billet is sintered at a high temperature to form a method for producing a porous sheet having high strength.

According to the conventional method for manufacturing a porous sheet, a granulated ceramic material is added to the billet, and the mixed billet is poured into a mold, and the sintered sheet is cooled by high-temperature sintering. A plate having a plurality of pores, such as the patent of the Republic of China Invention Patent Publication No. 200823165 "A ceramsite building material and a manufacturing method", discloses that the ceramsite building material includes: a plurality of ceramsites, and a foamed cement. The ceramsite is formed into a granular shape by sintering the clay at a high temperature, and has a particle diameter of between 3 mm and 8 mm and a volume percentage of between 75% and 85% of the total ceramsite building material. The foamed cement is a first-type foaming cement composed of a cement and an appropriate amount of a foaming agent, and the volume percentage after foaming is about 15% to 25% of the total ceramic building material. The foamed cement can be mixed with water and stirred, and the ceramsite is uniformly mixed and foamed to be in a mortar state, and then the mold is hardened and formed in a mold to form a combinable ceramsite building material.

Moreover, the above manufacturing method can produce the required porous sheet material according to requirements. It is to be noted that the pores of the manufactured porous sheet can be regularly arranged, the size or taper of the pore size can be controlled, the orientation is directional, and the pore can be controlled. The distribution on the board, etc., to solve the problem of the above-mentioned effects cannot be solved by the conventional method.

At the same time, through the straight tapered hole, not only can the plate be ventilated, but also the difference in capillary force between the two pieces of the plate, so that the indoor moisture can be smoothly discharged to the outside to become a functional green building material.

To achieve the above functions, a method for producing a high-strength liquid crystal glass composite material having pores by a puncture method comprises the following steps: A. forming an unsintered blank into a plate shape; B. a plurality of fine needles are inserted through the blank along the thickness direction of the blank; C. separating the plurality of fine needles from the blank to form an unsintered blank having a plurality of pores; D. sintering the blank having a plurality of pores by high temperature, the foregoing The billet is cooled after sintering to shrink the plurality of pores to form a sheet having a porosity.

The fine needles described above have a taper so that the pores of the sheet also have a taper.

The plurality of fine needles are simultaneously passed through the blank.

The plurality of fine needles are repeatedly passed through the blank.

The above blank is a composite material obtained by mixing liquid crystal glass and clay.

The effect of the invention:

1. The manufacturing method is simple: the blank before the sintering is pierced by a fine needle, and after sintering, the porous sheet can be made.

2. Low manufacturing cost: The invention has simple process, can reduce the manufacturing material cost, shorten the manufacturing time, and reduce the manufacturing cost.

3. Various parameters of the pores can be controlled: the pores of the sheet can be manufactured according to requirements, such as the size of the pores, the taper, the orientation of the pores, the distribution density of the pores, and the arrangement of the pores.

4. The manufactured porous plate has a capillary gradient: the pores of the plate of the invention have a tapered pore, which can make the capillary action of the plate have directionality. When used as a building material for the wall surface, in addition to being breathable, it can also be used to control the environmental humidity. .

5. A board made of a composite material obtained by mixing liquid crystal glass and clay, except It can effectively use recycled liquid crystal glass, and it also has excellent strength, and it becomes a functional green building material.
