Description

Technical Field

[0001] The utility model relates to the technical field of production, cutting and positioning of thermal insulation boards, in particular to an auxiliary positioning device for production and cutting of polyurethane thermal insulation boards. Background Art

[0002] Polyurethane insulation board Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35-40kg / m3, the thermal conductivity is only 0.018-0.024W / (m·k), which is about half of EPS and has the lowest thermal conductivity among all insulation materials. Rigid polyurethane is fireproof, flame retardant and high temperature resistant. After adding flame retardants, polyurethane is a flame-retardant self-extinguishing material. Its softening point can reach above 250 degrees Celsius and it will only decompose at higher temperatures: In addition, polyurethane will form carbon deposits on its foam surface when burning. This layer of carbon deposits helps to isolate the foam below. It can effectively prevent the spread of flames. Moreover, polyurethane does not produce harmful gases at high temperatures. After the polyurethane insulation board is produced, it is a larger board, which needs to be cut into polyurethane insulation boards of appropriate size.
