Description

A lightweight partition wall board with bactericidal function and its manufacturing method

technical field

The invention relates to the field of building materials, in particular to a lightweight partition wall board with a bactericidal function and a manufacturing method thereof.

Background technique

The lightweight partition board is a new type of energy-saving wall material composed of harmless phosphogypsum, light steel slag, fly ash and other industrial waste residues, and is cured by frequency conversion steam under pressure. The wall material is the same as the hollow floor slab, but there are male and female falcon grooves on both sides. When installing, you only need to stand up the board, and the male and female falcons can be assembled after applying a small amount of caulking mortar. It has the advantages of light weight, high strength, multiple environmental protection, thermal insulation, sound insulation, respiratory humidity control, fire prevention, rapid construction, and reduced wall cost, so it is very popular in the field of architectural interior decoration. Quality partition wall panels have disadvantages such as low compressive strength, weak tensile strength, poor crack resistance and hanging ability, high production cost, and poor sound insulation and heat preservation effects.
