Production technology for environmental protection energy-saving building base material by modifying AHF industrial residue-fluorgypsum

Abstract

The present invention discloses an improved base material of fluor gypsum; the component of the material comprises fluor gypsum, alkaline ash in metallurgy industry, water grind residue, coal ash powder in electrical power and coagulating; the molar percent of the material component is as follows: 50-80 percent of fluor gypsum; 5-15 percent of alkaline ash; 10-20 percent of water grind residue; 5-15 percent of coal ash powder; 0.5-3 percent of coagulating. The material has the advantages of waste recycle; the waste utilization technology solves the problem of three-waste treatment in AHF industry enough; the performance of the material is much better; the alkaline base material of fluor gypsum can be made into a plurality of building materials, which is with the character of gypsum and cement with light molar, high intension, low heat-conduction coefficient and small distensibility as well as heat-insulation and preservation function. The construction is convenient and fast; the material can save the energy and protect the environment; each building material made of the alkaline base material of fluor gypsum is without radioactivity; The material industry field is clean and safe without environment pollution; the whole process for the material does not need baking so as to save the energy. The investment is lower and the output is higher; the performance-price ratio of each building material made of the alkaline base material of fluor gypsum is much higher.

Description

technical field [0001] The invention relates to the technical field of building materials. Specifically, it is the production process of AHF industrial waste slag—fluorine gypsum modified to prepare environmentally friendly and energy-saving building materials. Background technique [0002] The production capacity of my country's AHF industry ranks first in the world, with a production capacity of about 800,000 tons / year, and the waste residue produced in the production - fluorine gypsum, is about 3 million tons / year, which is harmful to the environment. At present, the development of comprehensive utilization of waste slag is unbalanced. The utilization in the eastern region is mainly used as an auxiliary material in the cement industry, which is a low value-added utilization; due to the abundant cement resources in the western region, fluorine gypsum waste slag has not been utilized. In recent years, the building materials industry has developed rapidly, but it consumes ...
