Product characteristics of polyurethane composite panels

by:Ventech     2021-01-04
Polyurethane double cement base composite panels by double flexible surface material and polyurethane hard foam through a special production line of disposable continuous production and become, a sandwich structure. Double-sided non-woven through special processing, guarantee good bonding between the layers; Middle of PU rigid foam insulation layer adopts advanced mixing and cloth art, bubble hole is exquisite, uniform density, strength and heat insulation performance is reliable guarantee. 【 Polyurethane composite board]

product advantage

1. Coefficient of thermal conductivity is extremely low. Polyurethane rigid foam for thermal conductivity & le; 0. 024 w / m· K, is a very good building energy-saving materials, excellent heat preservation and heat insulation performance. Under the same heat preservation effect, 25 mm thick fengshun fuxing rigid foam insulation layer, the heat preservation effect is equivalent to 40 mm thickness of EPS, 45 mm thickness of mineral wool, 140 mm thick cork, 380 mm thick concrete or ordinary brick, 860 mm thick EPS thermal insulation layer thickness decreased by about 40%.

2. Thermal insulation, waterproof, sound insulation. Fengshun fuxing polyurethane rigid foam insulation layer water quantity is extremely low, the experimental results show that each moisture content increased by 1% v/v, its coefficient of thermal conductivity is only about 3%. At the same time, because warner polyurethane hard foam thermal insulation layer with excellent closed-cell structure, make it have good sound insulation function, can provide a comfortable, quiet indoor environment.

3. Since the adhesive power is strong. Warner insulation materials when compared with other production of polyurethane rigid foam with cement, steel, clay, asphalt, wood, glass, plastic and other materials for direct bonding, without any adhesive, bonding strength is greater than its own crack strength, fully meet the requirements of exterior wall thermal insulation engineering technology in China.

4. Physical and chemical performance is stable. Polyurethane rigid foam material to adapt to the temperature range is larger, can be in - 50℃本; 150 ℃ under the environment of use for a long time, short-term use temperature can reach 250 ℃, and the bubble does not produce any damage. Warner production of polyurethane rigid foam insulation layer physical and chemical performance is very stable, once forming reaction, insoluble in most of the solvent, is not affected by waste gas and industrial gases, not rot, resistant plastic, corrosion protection, tasteless, non-toxic.

5. Fireproof performance. Polyurethane rigid foam material can achieve fireproof performance requirements for high building insulation materials, namely, B1 and B2 flame retardant standard of building materials, and polyurethane rigid foam present in the combustion of inertia, meet fire surface carbonization, won't produce molten combustibility substance, so as to suppress the fire spread, the ignition point is higher than wood. Fire by the China construction science research institute of exterior wall thermal insulation system of rigid polyurethane do fire experiment showed that warner polyurethane hard foam external wall insulation system in not in case of fire burning fire, flame retardant performance can fully meet the requirements of building external wall fire protection standards.

6, due to the pu board with excellent insulation properties, under the same heat preservation requirements, and can make to reduce the thickness of the building envelope, thus increase the indoor use

7, resistance to deformation ability is strong, not easy craze, facing stability and security.

8, polyurethane material porosity structure stability, is essentially closed pore structure, not only the heat preservation performance is good, and freeze resistance, sound absorption. The average life expectancy of hard foam polyurethane insulation structure, under the condition of normal use and maintenance, can reach more than 30 years. 【 Polyurethane composite board]
