Problems solved by technology

[0002] At present, most of the popular wall bricks in the building materials market are made of clay, which not only has many technological processes, long production cycle, high labor intensity, high cost and heavy weight, but also uses a lot of clay, wasting a lot of good land The cinder cement bricks and concrete bricks discovered later do not need to be fired with clay, but because the surface is porous and rough, it needs to be smoothed and painted, and the surface decoration treatment requires many procedures, high cost, and troublesome operation

Embodiment 1

[0014] Example 1: Plaster, cement, hollow wall block bricks

[0015] ① Prepare the raw materials according to the ratio of water: plaster powder: cement=1:1.25:0.625, and make the mold; ②Soak the plaster powder cement in water for 1 minute, and then pour it into a mixer with a rotation speed of 120 rpm Stir for 3 minutes; ③Brick making: Pour the stirred gypsum cement slurry into the pre-made brick formwork and vibrate for 10-15 seconds, leave it for 3 to 5 minutes and then remove the film. ④Molding: place the demoulded brick body at room temperature for 18-25 minutes and then solidify and shape; ⑤inspect: arrange and inspect the molded brick body; ⑥store in storage. It is a rectangular parallelepiped gypsum cement hollow wall brick: that is, the surface of the brick body as the inner and outer walls of the wall is outside the plane, one surface and one side of the brick body are provided with convex keys, and the other surface of the brick body is A groove is arranged on the other...

Embodiment 2

[0016] Example 2: Plaster, cement, stone solid wall block bricks

[0017] Prepare the raw materials according to the ratio of water: plaster of paris powder: cement: stone=1:1:0.625:1.25, and make a mold, which does not have multiple through holes. The gypsum cement solid wall block bricks were produced by the methods ② to ⑥ in Example 1.

Embodiment 3

[0018] Example 3: Plaster solid partition wall brick

[0019] Prepare materials in a weight ratio of water: plaster of paris powder = 1:1.42, and prepare gypsum solid wall bricks by the method described in Example 1.

Abstract

A gypsum wall brick is made up of gypsum and cement or sand stone through preparing raw materials, making mould, preparing plaster powder, making bricks, solidification by cooling, trimming and examination. Said brick has white front and back surface, tenons in the center of top and left sides, and mortises in the center of bottom and right sides. When a wall is built-up, adjacent bricks can be matched and adhered by special adhesive. Its advantages are simple production technology, high strength and thermal and acoustic insulating effect, low cost and light weight.

Description

(1) Technical field [0001] The invention relates to a wall brick, in particular to a gypsum wall brick made of gypsum, cement or sandstone. (2) Background technology [0002] At present, most of the popular wall bricks in the building materials market are made of clay. Not only does it have many technological processes, long production cycles, high labor intensity, high cost and heavy weight, but also uses a lot of clay, which wastes a lot of fertile land. The later discovered cinder-cement bricks and prefabricated concrete bricks do not require clay to be fired, but due to their porous and rough surface, they need to be smoothed and painted and the surface finishes are treated, which requires many procedures, high costs, and troublesome operation. (3) Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing wall bricks, the present invention provides a gypsum wall brick that does not require soil, does not need to be fired, has hig...
