Problems solved by technology

However, these methods all use high-temperature calcination, the adhesion of sludge particles is not enough, the ceramsite calcination process is easy to crack and loose, and the defective rate is high; the toxic and harmful substances in the sludge during high-temperature calcination decompose into harmful gases, polluting the environment, threatening Personnel health; high fuel consumption and high energy consumption lead to high production costs and reduce the market competitiveness of wall panels

Abstract

The invention discloses a manufacturing method of an environment-friendly ceramsite wallboard, belonging to the technical field of building materials. The invention aims to solve the problems that ceramsite is easy to crack, a defective rate is high, harmful gas is generated to pollute the environment, cost is high, product competitiveness is insufficient and the like in the prior art. According to the manufacturing method of the environment-friendly ceramsite wallboard, low-temperature cracking is adopted, and the adhesive is added into the sludge, so ceramsite is not prone to cracking, and a defective rate is reduced; ceramsite prepared from the sludge is cracked at low temperature, no harmful gas is generated, and safety and environmental protection are achieved; and a manufacturing process is low in temperature requirement and low in energy consumption, so production cost is remarkably reduced, and product competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for manufacturing an environmentally friendly ceramsite wallboard. Background technique [0002] With the acceleration of urbanization, people's demand for housing is gradually increasing, and the requirements for building strength, load-bearing, installation and environmental protection are also getting higher and higher. The improvement of building material performance has become a hot topic in the construction industry. At present, it has become a common practice in the industry to add ceramsite to wallboards to improve the performance of wallboards in terms of strength, air permeability, and sound insulation. However, the clay suitable for ceramsite raw materials is limited and the cost is high. Therefore, it is urgent to find a Substitutes to solve the problem of ceramsite raw materials. At present, there are precedents of using domestic sludge as raw ma...
