Embodiment 1

[0038] Corn stalks (plant diameter 1.8cm~2.6cm) were used as straw raw materials, and No. 425 Portland cement was used as the base material to make ecological straw bricks, which were applied to an ecological slope protection project in the Taihu Lake area. The manufacturing and engineering application process of porous permeable bricks are as follows: (1) remove the side leaves of the straw and put it into a pulverizer, and crush it into particles with a length of 1cm~3cm; (2) put the crushed straw particles into a modulus of 3.0 Soak in water glass solution with a Baume degree of 50.0 for 30 minutes, take it out and dry it naturally for 24 hours; (3) Soak the straw particles coated with water glass film in tung oil for 5 minutes, take it out and dry it naturally for 24 hours; ( 4) Combine straw particles, cement, river sand, water glass (modulus 3.0, Baume degree 30), chopped glass fiber filaments (length 5cm), cement foaming agent and water at 100:80:50: Put the mass ratio ...

Embodiment 2

[0040] Sorghum straw (plant diameter 1cm~1.2cm) was used as the straw raw material, and No. 425 Portland cement was used as the base material to make ecological straw bricks, which were applied to an ecological slope protection project in the Taihu Lake area. The manufacturing and engineering application process of porous permeable bricks are as follows: (1) Remove the side leaves of the straw and put it into the pulverizer, and crush it into particles with a length of 1cm~3cm; (2) Put the crushed straw particles into the modulus of 3.0 Soak in water glass solution with a Baume degree of 50.0 for 30 minutes, take it out and dry it naturally for 24 hours; (3) Soak the straw particles coated with water glass film in tung oil for 5 minutes, take it out and dry it naturally for 24 hours; ( 4) Combine straw particles, cement, river sand, water glass (modulus 3.0, Baume degree 30), chopped glass fiber filaments (length 5cm), cement foaming agent and water at 100:80:50: Put the mass ...

Abstract

The invention discloses a preparation method and device for a bottom blowing type photocatalytic porous permeable brick. The preparation device for the bottom blowing type photocatalytic porous permeable brick is characterized by comprising a forming die, a breathable end cover, a porous lining board, a draw bar, a nylon mesh, an air inlet pipe and a water draining pipe. The preparation method for the bottom blowing type photocatalytic porous permeable brick comprises the following steps: (1) smashing straw into particles with the length of 1-2cm; (2) putting the straw particles into a water glass solution to be soaked for 30 minutes, then taking out, and drying; (3) soaking in tung oil for 5 minutes, and then drying; (4) uniformly mixing the straw particles, cement, river sand, water glass, chopped fiber glass filaments, a cement foaming agent and water; (5) pouring mixed slurry into the forming die, and introducing CO2 gas at the temperature of 80 DEG C for curing; (6) drying for 5-7 days; (7) carrying out heat preservation on a porous brick for 1 hour at the temperature of 150 DEG C, slowly heating to 400 DEG C, carrying out heat preservation for 5 hours, and carrying out furnace cooling; and (8) impregnating and drawing a porous permeable brick in a photocatalytic plating solution for 5 minutes and then drying, and repeating for 3-4 times, so that the photocatalytic porous permeable brick is obtained.

Description

technical field [0001] The invention relates to a preparation method and device of a bottom-blown photocatalytic porous permeable brick, belonging to the technical field of composite material forming. Background technique [0002] In recent years, with the continuous acceleration of the industrialization process, at the same time, the production technology of enterprises is backward, the management level is low and the material consumption is high, resulting in excessive discharge of pollutants per unit of product, and the large amount of waste water and gas generated seriously affects human health. and living environment, environmental pollution control has become one of the important problems facing and urgently to be solved in modern society. The methods currently being used such as chemical oxidation, physical adsorption, high-temperature incineration and microbial treatment have played a certain role in environmental protection and governance, but these methods have som...
