Cold storage pu insulation material(insulation + waterproof)
Source： │ Datetime：2020-04-15
The cold storage pu insulation material has functions of heat preservation and waterproofing. In recent years, with the rapid development of the building energy-saving market in China, polyurethane rigid foam insulation products have been widely used in the field of building insulation and waterproofing, and have become a market-leading insulation energy-saving product. The rigid polyurethane foam breaks the single function of traditional building materials, waterproof and non-insulated, and the insulation is not waterproof. Once the waterproof layer leaks, the insulation layer immediately loses the common function of the insulation function. Compared with other single-function insulation or waterproof materials, polyurethane rigid foam has obvious advantages: . Rigid polyurethane foam has multiple functions and functions, such as thermal insulation, waterproofing, sound insulation, and vibration absorption; . Insulation performance is the lowest thermal conductivity of all building materials (lower than green fluorine-free foam technology), and the thermal resistance of insulating materials is only half of the thermal resistance of polystyrene board; . Rigid polyurethane foam has a continuous dense skin, close high-strength closed-wall closed cells, and has ideal water resistance. The waterproof insulation layer is continuous without joints, and is formed by a seamless roof and the outer wall insulation shell spraying method, which has excellent waterproof and impermeability performance;
Polyurethane foaming technology is inseparable from polyurethane foaming machine. Excellent quality polyurethane foaming machine is the only choice for producing polyurethane insulation materials.
