Production technology of composite water permeable brick

Abstract

The invention relates to the field of composite type building materials, in particular to a production technology of a composite water permeable brick. The production technology of the composite water permeable brick comprises five steps of water permeable surface layer distribution, water permeable basement layer distribution, pressurization vibration forming, demoulding and maintenance brick delivery. In the pressurization vibration forming, pressure balanced devices which are respectively connected with each pressure head control the mould pressing pressures thereof, and the water permeable basement layer distribution also comprises a step of fixing a bottom die at the corresponding position of an upper die. The bottom die completes the water permeable basement layer distribution before being transferred to a compacting press, so the method of the invention prevents the pressure heads from being contacted with viscous materials; and meanwhile, a distribution treatment device smoothly clears up the materials of a water permeable surface layer, so the pollution and material bonding of the pressure heads are avoided, the surface quality and compactionness of the produced water permeable bricks are ensured to be uniform.

Description

technical field [0001] The invention relates to the field of composite building material manufacturing, in particular to a preparation process of a composite permeable brick. Background technique [0002] At present, the permeable materials used in permeable bricks and permeable pavements on the market are mainly ceramics or concrete. Ceramic permeable bricks use a large amount of mineral resources, so the mining of raw materials has caused environmental damage. The production process of ceramic permeable bricks is complicated, and the ceramic base bricks require a lot of energy when forming and sintering, with high cost, low production efficiency, large investment in environmental protection, and large one-time investment scale. Although the cost of concrete permeable bricks is low, the existing concrete permeable bricks have large particles on the surface (generally, the particle size of aggregate particles is 3mm to 6mm), and the large pores on the surface are permeable t...
