1. Market prospects for lightweight energy-saving composite wall panel equipment: As a new wall material, lightweight wall panels are widely used in interior walls, exterior walls, roof walls, fences, etc., which can speed up construction, reduce labor intensity, and shorten the construction period. Reducing project costs and effectively increasing the usable area of buildings is the direction of wall reform.
The State Council stipulates that starting from July 1, coastal cities and other cities with scarce land resources will ban the use of clay bricks and restrict the production and use of other clay products.
The national "Ninth Five-Year Plan for National Economic and Social Development and the Outline of Long-term Goals for 2021" once again emphasizes that the construction industry focuses on high-speed construction, energy conservation, waste recycling, water conservation, and pollution reduction, speeding up the transformation of old enterprises, and vigorously Increase high-quality products, develop new building materials products, limit the production and use of clay, and actively use industrial waste residue to produce wall materials. Therefore, this product is in line with the industry direction and national wall reform policy.
The overall requirement for the development of walls is to develop from clay to non-clay, solid to hollow, small pieces to large pieces, and heavy to light. Lightweight wall panels are precisely because of their lightness, environmental protection, and Energy saving, waste recycling, high efficiency, high quality and low price make it the first choice for construction projects.
2. Raw materials for the production of lightweight energy-saving composite wallboard equipment products:
There are three types of cementitious materials for lightweight wallboards: cement, gypsum, magnesium chloride and magnesium oxide. There are many materials that can be used for filling, such as fly ash, cinder, straw, foam, slag, ceramsite, construction waste, etc. Production companies can choose based on local resources and local conditions.
There are three main types of wall panels currently promoted and used in the market:
, R lightweight wall panels: using fast-hardening cement as the cementing material, adding fly ash, perlite and glass fiber mesh , after mixing and pouring.
Magnesite wall panel: It uses magnesium chloride and magnesium oxide as cementing materials, adds fly ash, sawdust, straw and glass solder mesh cloth, and is formed by stirring and pouring.
Reinforced gypsum wallboard: Use gypsum powder as the cementing material, add fly ash, lightweight materials and fiberglass mesh, and then stir and pour into shape.
The cost of lightweight wall panels produced by the above three types of cementitious materials is basically the same. In comparison, the cost of R lightweight wall panels is slightly lower.
When the above three types of cementitious materials are produced using the same equipment, using gypsum as raw material has the highest yield and can be demoulded in half an hour, fast hardening cement takes 2 hours, and magnesium chloride and magnesium oxide take 3 hours.
