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, the domestic metal faced rigid polyurethane sandwich board is widely used in industrial workshop, warehouse,
stadium, civil residence, villa, movable board room, combined cold storage and other buildings, but the disadvantage is that it is carried out under the condition of reaction of high temperature and strong alkali, with 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
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.
wool color steel sandwich board
The rock wool color steel sandwich board in the color steel plate has good fire-proof performance, but the rock wool color steel plate is not waterproof, which produces toxic substances in case of fire and causes
5. Paper honeycomb color steel sandwich panel
The paper honeycomb sandwich board can completely recycle and reuse the waste. It is a new generation product of polystyrene board, polyurethane, rock wool and other materials,
widely used in clean engineering fields such as electronics, operating room, laboratory, etc., but with poor waterproof effect and high price
6. Aluminum core sandwich panel
Aluminum honeycomb color steel sandwich panel, which is made of aluminum
honeycomb core panel, composite with special high-strength glue and color steel plate, and supported by special aluminum alloy keel, after heating, pressing and curing. Compared with other sandwich boards, they are light in weight, good in straightness,
green building materials, but high in cost.
