Polyurethane board ChengJianZhu heat preservation material 'mainstay'
in the same building area, using pu heat preservation material its building usable floor area is better than using other heat preservation material 1% ~ 1. 5%, for external wall insulation, when the insulation layer thickness of more than 10 cm, can increase the difficulty of construction, more important is the security system will be affected by the larger, and the risk of using polyurethane material will be lower, the system safer.
compared with other monofunctional insulation or waterproof material, polyurethane rigid foam has the function of a material is multi-purpose and thermal insulation, waterproof, sound insulation, vibration absorbing, and many other functions. This material is the lowest of all domestic building materials coefficient of thermal conductivity ( & le; 0. 024). Value, is the highest heat preservation material coefficient of thermal conductivity is only half of the EPS foamed polystyrene plate.
continuous density polyurethane hard foam body skin and close to 100% of the high strength interconnected wall hole closed, waterproofness with ideal. By spraying method can achieve waterproof insulation layer continuous jointless construction, form a seamless exterior wall thermal insulation shell, roof and the overall excellent water permeability resistance.
the super viscosity can, can and roofing and external coherence is firm, good wind jie and negative wind pressure resistance. The whole spraying construction in engineering, and can completely eliminate & other; Hot day & throughout; And & other Cold bridge & throughout; , flexible waterproof layer gradient technology can effectively prevent craze. Polyurethane hard foam flame can self-extinguishing, and only when burning carbonization not drip drip, partition into the air, can effectively prevent the fire from spreading.
I company production of polyurethane panels are of good quality, also more and more widely, the scope of its use in need of friends can inquire the choose and buy.
