How can I cut the polyurethane foam board?
You find a factory where there are cutting benzene plate cutting machine, you can wire cutting, ultra heat preservation materials, you go to ask.
Cutting machine can be wire cut, you go to ask over 100 million thermal insulation material
You have to find a benzene board factory, there is cutting benzene plate cutting machine, you can wire cutting.Can also buy a polyurethane foam board, manual cutting machine for manual cutting.
Usage methodStep 1: shake it 15-30 times before use, up and down;The second step: before construction, clean the filling area and spray it with water;The third step: turn the tank upside down and rotate it at the nozzle of the gun / hose. Turn the spray gun flow valve adjustment counterclockwise;The fourth step: spray from bottom to top, spray volume to 80% of the required volume of filling (tube filling volume of 2/3);The fifth step: ten minutes after the beginning of dry surface, one hour after curing, further processing;The sixth step: cured foam, can use a sharp knife to remove excess parts, and then in the surface with cement mortar, paint or silica gel processing.
You find a factory where there are cutting benzene plate cutting machine, you can wire cutting, ultra heat preservation materials, you go to ask.Rigid polyurethane foam with isocyanate and polyether as the main raw material, the foaming agent, catalyst and flame retardant additives under the action of special equipment by mixing polymer by high pressure spraying foam into. There are two kinds of polyurethane foam: soft foam and hard foam. The soft foam is an opening structure, the hard foam is the closed cell structure, and the soft foam is divided into two kinds: the crust and the non crust.The main function of polyurethane soft foam is to cushion. Soft polyurethane foam is commonly used in sofa furniture, pillows, cushions, toys, clothing and noise insulation lining.Polyurethane foam is a kind of new synthetic insulation materials and waterproof function, its low thermal conductivity, only 0.022~0.033W/ (m* K), equivalent to half of the board, is the thermal conductivity of thermal insulation material in the lowest of all. Rigid polyurethane foam is mainly used in building exterior wall insulation, roofing waterproof and thermal insulation integration, cold storage insulation, pipe insulation materials, building plates, refrigerated trucks and cold storage insulation materials.
