What are the main types of insulation materials for building exterior wall
Fastening steel pipe scaffolding erection sequence: placed sweeping large bar → root by root to establish the pole (then with the sweeping large bar buckle) → installed a small cross bar (then with the pole or swept the big bar buckle) → the first step of a large cross-stalk (then with the pole fastening) → An early step small bar → installation of the second step of large cross-cutting → installation of the second step of the small bar → add temporary oblique strut (upper And the second step of the big cross-fastening
Currently on the market of insulation materials are divided into organic and inorganic two, organic materials, good insulation properties, but poor flame retardant properties, inorganic materials, good flame retardant properties, high thermal conductivity, poor insulation properties, such as fiber-like materials and pollution of the environment Bacteria and other ills. Phenolic insulation board It has excellent fire, heat insulation, noise, light energy and other properties, heat, flame retardant self-extinguishing, flame-resistant penetration, in case of fire without dripping and to prevent the flame spread fire resistance and so on. Phenolic board thermal conductivity less than 0.25W / (m.K), better than polystyrene board extruded board and other materials. 25 mm thick phenolic fire insulation board subjected to flame spray at 1700 ℃ for 10 minutes, only the surface slightly carbonized and will not be burned, is the best fire insulation sheet.
The length of the long and wide can not be enraged, but because the different structures required for the full standard is not the same, the ordinary floor and bridge a lot worse, I suggest you look for this specification or budget quota to see.
