Problems solved by technology

For this reason, cause this kind of brick to have many fatal injuries
Poor compactness Because unburned bricks save the steam curing process in the autoclave, they lose the curing process under more than 10 atmospheres. meet quality requirements
Non-steaming and non-burning fly ash bricks are one of the new wall materials developed in recent years. Most enterprises do not operate well after production. Some products cannot compete with clay bricks in terms of cost and quality. Wall materials, which mix renewable natural resource wood, fly ash, cement, and industrial waste in a certain proportion with water to make blocks or plates, but the maintenance time is long, and the strength and quality are difficult to guarantee, while In order to eliminate hidden dangers of project quality, protect people's lives and property safety, and promote the healthy and orderly development of the new wall material market, Xiangcheng County, Henan Province decided to prohibit the use of non-steaming and non-burning bricks in various construction projects, but vigorously promote the use of The level of craftsmanship and technology is high, the product quality is stable, and the non-steaming and non-burning bricks that meet the building codes and new wall product standards have far-reaching significance and long-term high economic value

Embodiment 1

[0028] The present invention is achieved through the following technical solutions:

[0029]Step 1, hydrothermal treatment of modified active sludge: in parts by weight, add water to 71 parts of modified active sludge to make its moisture content 51%, and mix 138 parts of dry powder and diethylene triamine pentacarboxylic acid Crush 7.4 parts of sodium to 200 mesh, mix the crushed mixed dry powder and sodium diethylenetriaminepentacarboxylate mixture with modified active sludge after adding water at 10°C, and accumulate for 10 hours to obtain mixture A; Add 3% slaked lime in the total mass of mixture A and mix evenly, then heat in a microwave hydrothermal kettle at 170°C for 1 hour while stirring, then cool down, and obtain a hydrothermally treated mixture B after cooling, wherein the microwave heating frequency is 2500MHz; step 2, preparation Modified polyphosphazene: under the protection of nitrogen, weigh 45 parts of tetrahydrofuran solution containing polydichlorophosphaze...

Embodiment 2

[0032] Step 1, hydrothermal treatment of modified active sludge: in parts by weight, add water to 68 parts of modified active sludge to make its moisture content 47%, and mix 115 parts of dry powder and diethylene triamine pentacarboxylic acid Grind 6.1 parts of sodium to 100 mesh, mix the pulverized mixed dry powder and sodium diethylenetriaminepentacarboxylate mixture with modified active sludge after adding water at 10°C, and obtain mixture A after stacking for 6 hours; Add slaked lime of 2% of the total mass of mixture A to the mixture and mix evenly, then heat in a microwave hydrothermal kettle at 160°C for 0.5h while stirring, then cool down, and obtain a hydrothermally treated mixture B after cooling, wherein the microwave heating frequency is 2450MHz; Step 2, Preparation of modified polyphosphazene: under the protection of nitrogen, weigh 40 parts of tetrahydrofuran solution containing polydichlorophosphazene with a mass fraction of 10%, and add 12 parts of tetrahydrofu...

Abstract

The invention discloses a method for preparing rapid-forming non-steaming and non-burning bricks. The invention belongs to the technical field of non-burning bricks. , without long-term oxidation, the unburned brick prepared by the disclosed preparation method does not contain cement gelling agent, has accurate size, high density, high compressive strength, good frost resistance, good sound insulation, heat insulation and thermal insulation performance of unburned brick, and Rapid prototyping shortens the molding cycle, further increases the output, is easy to operate, does not require long-term maintenance, and has rich sources of raw materials. The use of cheap resources such as industrial waste and active earthworm sludge is conducive to rapid production on the assembly line. It not only realizes turning waste into treasure, And reduce the environmental burden.

Description

technical field [0001] The invention belongs to the technical field of burn-free bricks, and in particular relates to a method for preparing rapid-formed steam-free burn-free bricks. Background technique [0002] Non-steaming and non-burning bricks are made of fly ash, coal rock, various slags or other clays, shales, etc., mixed with cementing materials, reinforcing agents, etc. Autoclaved and normal pressure curing, bricks formed by natural curing. my country began to produce unburned bricks in 1980. After the introduction of the national wall reform policy in 1991, wall products other than clay solid bricks were designated as new wall materials. For this reason, unburned bricks have developed rapidly. At present, the national annual output is about 3 billion pieces. Non-steaming and non-burning bricks, the technology is sintering-free and autoclaving-free. After the product is pressed and formed, it is transported to the blank yard and placed at room temperature for mor...
