Prefabricated Assembly House Materials
Prefabricated assembly house materials mainly include prefabricated structural materials, prefabricated wall materials, prefabricated interior and exterior decoration materials, landscape materials, materials related to integrated houses, and floor component materials, etc..
Among prefabricated structural materials, steel structures are relatively common. They use economically produced steel profile components as load-bearing skeletons, featuring high strength, light weight, good overall rigidity, and strong deformation capacity. They are suitable for constructing large-span and super-high, super-heavy buildings.
There are various types of prefabricated wall materials. Cement wall panels are lightweight partition panels made from a mixture of harmless phosphogypsum, lightweight steel slag, fly ash, and other industrial waste residues with cement as the raw material. They are cured through variable-frequency steam pressure and have a shape similar to hollow floor slabs with male and female grooves on both sides. Wood-plastic composite wall panels use inorganic aggregates such as fly ash and tailings sand as the main materials, with polymer as the bonding material, and are mixed with flame retardants and other additives in a certain ratio and process, and then extruded into shape. Wall panels in PC components are pre-fabricated in component processing plants according to design drawings, including interior wall panels and exterior wall panels, and are mainly used in prefabricated concrete systems.
In terms of prefabricated interior and exterior decoration materials, inorganic interior wall decoration panels use siliceous materials, calcareous materials, add plant fibers and various organic and inorganic substances, mix them in a certain proportion, and use advanced program-controlled equipment and flow slurry process to produce calcium silicate boards as the base material, which are then processed through advanced techniques. SPC wall decoration panels (also known as rigid plastic wall panels) are made by mixing polyvinyl chloride, heavy calcium carbonate, processing aids, and other materials in a certain proportion, plasticizing them, and then using an extruder and specific molds to form the base material. The UV layer, wear-resistant layer, etc., are then processed using a four-roll calender.
Among landscape materials, wood-plastic composite materials use primary biomass materials such as wood chips, wheat straw, and chaff as the main raw materials, utilizing the principles of polymer interface chemistry and the characteristics of plastic filling modification. They are mixed with a certain proportion of plastics and additives as the base material and processed through special techniques. Green ecological hanging panels mainly use powdery hydraulic inorganic cementitious materials, siliceous materials, and fibers as the main materials. They are vacuum-extruded, cured through high-temperature and high-pressure secondary steam, and then cut, painted, or produced using unique 3D printing coating techniques.
Integrated houses use standard containers as the basic units and can be freely combined horizontally or vertically in various forms like building blocks, with flexible spatial layouts and prefabricated functions, achieving diversified usage functions. Floor component materials include prefabricated hollow slabs and叠合板 (laminated slabs) and stairs in PC components. The former are pre-fabricated in factories with cylindrical holes in the middle, while the latter are also pre-fabricated in component processing plants according to design drawings and are used in prefabricated concrete systems.
