According to the chemical composition of the products, the core material of color steel can be divided into two categories, namely, organic chemical foam materials, such as polystyrene foam EPS, polyurethane foam PU, extruded polystyrene foam XPS, phenolic foam PF, etc. The other is inorganic fiber materials, such as rock wool board, foamed cement board, etc.
1, polyurethane foam color steel sandwich panels PU
Polyurethane foam color steel sandwich panels are made of flame retardant rigid polyurethane foam core and color coated steel sheet. At present, domestic metal faced rigid polyurethane sandwich panels are widely used in industrial plants, warehouses, stadiums, civil houses, villas, movable plank houses, combined cold storage and other buildings, but the disadvantage is that they are carried out under the condition of reacting high temperature and strong alkali, have high requirements for equipment, large initial investment and difficult industrialization.
2, polystyrene foam color
steel sandwich panels EPS
Polystyrene is the white foam we often see. This kind of color steel plate is cheap, water resistant and non deformed. Most of the movable rooms on the site are built of polystyrene sandwich panels, which are widely used, but the polystyrene foam sandwich panels are not fireproof, and the thermal insulation effect is rather poor.
3, phenolic foam color steel sandwich panels PF
Phenolic foam color steel sandwich panels are made of colored steel sheets and phenolic foam as core material. Phenolic foam is brittle, brittle and corrosive. The residual acid in the foam has corrosion effect on metal materials.
4. Rock wool color steel sandwich panel
The rock wool color steel sandwich board in Jinan color steel plate has good fire prevention performance, but the rock wool color steel plate is not waterproof and produces toxic substances in case of fire.
5. Paper honeycomb color steel sandwich panel
Paper honeycomb sandwich board can completely recycle and reuse waste. It is a replacement product of polystyrene board, polyurethane, rock wool and other materials. It is widely used in clean engineering fields such as electronics, operating room and laboratory, but its waterproof effect is poor and the price is expensive
6. Aluminum honeycomb sandwich panel
The aluminum honeycomb color steel sandwich plate is made of aluminum honeycomb core plate, compounded with special high-strength glue and color steel plate, supported by special aluminum alloy keel, heated, pressurized and cured. Compared with other sandwich panels, it has light weight and good flatness. It belongs to green environmental protection building materials, but the cost is high.
The above are several different types of sandwich panels introduced by Jinan color steel plate manufacturers today. Their different functions and different properties make them more prominent on different occasions.
