Polyurethane Foam Insulation Board for sale

Polyurethane Foam Insulation Board for sale Product Introduction: Polyurethane rigid foam panel is a new type of synthetic material with thermal insulation and waterproof functions. Thermal conductivity of PU board is low, only 0.022~0.033W/(m* 螝)锛?It is equivalent to half of the extruded panel and is the lowest thermal conductivity among all thermal insulation materials so far. Rigid polyurethane foam plastic is mainly used in building exterior wall insulation, roof waterproof and insulation integration, cold storage insulation, pipeline heat insulation materials, building panels, refrigerated vehicles and cold storage insulation materials,etc. PU foam is a kind of thermal insulation material. Polyurethane rigid foam of PU board is a high polymer foamed on the spot by high-pressure spraying with isocyanate and polyether as the main raw materials, mixed by special equipment under the action of foaming agent, catalyst, flame retardant and other additives. There are two types of polyurethane foam: soft foam and hard foam. The soft foam is open cell structure, and the hard foam is closed cell structure. The soft foam is divided into two types: crust and non-crust. pu foam board is widely used in almost all sectors of the national economy, especially in furniture, bedding, transportation, refrigeration, construction, thermal insulation and other sectors. Product Advantage PU board: 1. Light-weight &high-intensity 2. fire resistant & insulation 4. Corrosion resistant, non-absorbent 5. easy to clean & install 6.

The cleaning before construction is very important, otherwise it will directly affect the quality of the insulation pu foam panel paste construction . The remaining floating ash, release agent oil stains and other debris on the concrete wall must be removed. 2. The concrete blocks and inclusions split at the joint of the shear wall shall be chiseled and repaired again; The cornice shall be sloped with cement mortar according to the design, the wall will be filled with a variety of openings. 3. Before the construction of the insulation PU board, the wall surface must be checked and accepted. The flatness deviation is required to be no more than 4mm. If the deviation is out of tolerance, the protruding wall surface shall be polished, and the concave part shall be repaired (if the repair thickness is more than 6mm, the 1:2.5 cement mortar shall be used for plastering, and if the repair thickness is less than 6mm, the polymer bonding mortar shall be used for repairing) to ensure that the flatness of the entire wall surface is within 4mm, the Yin and Yang Angle is square and smooth .The leveling layer shall be firmly bonded to the wall without coating, hollowing or gaps. The surface layer shall not have the phenomenon of pulverization, peeling, ash blasting, efflorescence, etc. Application areas rigid polyurethane PU board: Polyurethane pu foam board has become an indispensable material for thermal insulation, waterproofing, leak-proofing, and sealing in industrial sectors such as construction, transportation, petroleum, chemical industry, electric power, and cold storage.
