Method for continuously producing environment-protection light gypsum wall material by using industrial residue

Abstract

The present invention discloses process of producing light wall material with industrial solid waste, carbon residue, fly ash, natural gypsum, lime, cement and small amount of chemical material in a continuous production line. The production process includes the following steps: washing ardealite, adding lime for neutralizing, mixing ardealite in 70 wt% and natural gypsum in 30 wt%, dewatering, air drying, calcining, grinding, ageing and other step to prepare beta type semi-hydrated gypsum powder; mixing semi-hydrated gypsum powder, phosphate slag or carbon residue, fly ash, cement and small amount of chemical material in certain weight proportion; adding water to form slurry and forming light wall block.

Description

Method for continuously producing environment-friendly lightweight gypsum wall material by utilizing industrial waste residue technical field The invention relates to a new type of lightweight wall material, in particular to a large-scale production of a new type of light weight wall material by using various industrial waste residues, certain natural gypsum ore and trace chemical raw materials through mechanized production lines. It belongs to the field of building materials. Background technique At present, there is no large-scale application of phosphogypsum, and a large number of piles have been formed in many areas, while various other industrial wastes are also increasing. polluted environment. For this reason, people are also constantly exploring new methods and new ways to effectively utilize various industrial wastes. Although there have been many methods to comprehensively utilize various industrial wastes so far, there have been no reports on the comprehensive...
