Polyurethane board manufacturer about outer wall heat preservation material according to the shape classification
1, the overall heat preservation and heat insulation materials: usually make aggregate with loose heat insulation heat preservation material, casting or spraying surface into chongqing wall thermal insulation material, such as vermiculite, expanded perlite concrete, concrete lytag concrete, clay ceramsite concrete, pumice concrete, slag concrete, this kind of material is still has the original some performance of loose material, good entirety, construction is convenient, most belong to a-class non-combustible insulation materials.
2, the outer wall heat preservation material is loose heat insulation heat preservation material such as slag, water slag expanded vermiculite mineral wool rock wool expansion perlite sawdust and rice husk, etc. , it should not be used in both vibration and retaining structure.
3, plate heat insulation heat preservation material: exterior wall thermal insulation material is generally loose loose heat insulation heat preservation material products or chemical synthetic polyester and synthetic rubber materials, such as mineral wool board, vermiculite stone, foam plastic board, cork board, and organic fiberboard ( Fiberboard, particleboard, straw board and cane board, etc. ) , as well as foam concrete plate, it has some properties of loose material, processing is simple, construction is convenient.
