average cost of inground hot tub.Continuous production line for metal carved exterior wall panels

　　The continuous production line for metal carved exterior wall panels is a decorative wall panel mainly made of polyurethane foam, which is a new environmentally friendly and lightweight building material currently popular internationally. It can produce fireproof, flame-retardant, and thermal insulation decorative wall panels with a surface of steel plate, a middle of polyurethane, and a bottom of aluminum foil or steel plate. The continuous production line of polyurethane foam insulation board mainly consists of unwinding machine, embossing machine, leveling machine, side molding machine, heating platform, AB material foaming machine injection, laminating machine, sawing board cutting, coloring, packaging, etc.

　　Polyurethane has excellent performance and good insulation effect.

　　Polyurethane hard foam has a large number of foam pores inside and is interconnected, with evenly distributed foam pores that can effectively absorb and block sound. Therefore, it has good sound insulation effect and can provide a quiet and comfortable indoor environment for buildings.

　　High bonding strength

　　Polyurethane hard foam materials have strong bonding strength and can be bonded to various materials such as cement, steel, clay, asphalt, wood, glass, plastic, etc. The bonding strength is greater than its own crack resistance, fully meeting the technical requirements of external wall insulation engineering in China.

　　High compressive strength

　　Polyurethane hard foam products have excellent dimensional stability and strong resistance to external deformation, especially under adverse factors such as external force, humidity, temperature, and dryness, and will not crack. Therefore, they can effectively maintain overall stability and durability.

　　Good weather resistance and long service life

　　The hard foam polyurethane after physicochemical treatment can be used normally for 30 years at temperatures below 130 ℃, and can be used for over 70 years at temperatures below 50 ℃.
