Manufacturing process of permeable bricks capable of absorbing waste gas and permeable bricks produced by this process

Abstract

The invention discloses a process for manufacturing water permeable bricks capable of adsorbing waste gas. The process comprises the following steps: manufacturing a base material, namely mixing silicate cement, gravel with particle diameter of 3-8mm and active carbon with clear water, uniformly stirring, and filling a forming machine with the stirred mixture serving as the base material of water permeable bricks; mixing the silicate cement, gravel with the particle diameter of 3-8mm, zinc oxide, kieselguhr, active carbon and mineral pigment with clear water, uniformly stirring, filling the forming machine with the stirred mixture which serves as a surface material of the water permeable bricks and is put on the base material, and jointly pressing and forming the surface material and the base material by virtue of high-frequency vibration of the forming machine; mixing nano titanium dioxide powder with water and spraying the mixture of titanium dioxide and water to the water permeable bricks formed in the second step; and maintaining the water permeable bricks coated with titanium dioxide until the design strength is achieved. The top projection of brick bodies manufactured by the process is square; water permeable holes passing through the brick bodies are uniformly distributed in the top surfaces of the brick bodies; and cross-shaped grooves are formed in the bottom surfaces of the brick bodies.

Description

technical field [0001] The invention relates to the field of building material manufacturing for public facilities, in particular to a manufacturing process of an ecological permeable brick capable of absorbing waste gas and the permeable brick manufactured by the process. Background technique [0002] The permeable brick used for street pavement is a kind of brick body with strong water absorption function, while the material of ordinary permeable brick is the porous concrete material of ordinary crushed stone, which is formed by pressing and used for sidewalks and squares in general blocks. paving products. This kind of ordinary water-permeable installation can only achieve simple urban surface hardening, has certain water-permeable and water-seeping functions, and can decorate the ground. [0003] Because the urban ground is covered by a large amount of concrete pavement or brick pavement, it is impossible to grow green plants in large quantities. Therefore, the urban a...

Problems solved by technology

[0003] Since the urban ground is covered by a large amount of concrete pavement or brick pavement, it is impossible to grow green plants in large quantities

Therefore, the city's air pollution index is high, and the city's self-purification ability is poor.
