Product Description
The fabric base material of the membrane material should be polyester or polyamide fiber fabric. The coating is mainly polyvinyl chloride () resin. The weight of different coatings should be between ~/ according to functional requirements. The surface layer should be polyvinylidene fluoride resin, polyvinylidene fluoride resin (), polypropylene resin () , silicone resin, etc., and should have the function of improving the self-cleaning and anti-aging properties of membrane materials. The thickness of the membrane material should be greater than... The surface layer should have stable corrosion resistance and ultraviolet erosion resistance during the shelf life, and should have self-cleaning properties.
Key points for selection
) The surface layer of the membrane material should have stable resistance to corrosion and ultraviolet erosion during the shelf life, and the surface should have self-bonding properties.
) When the membrane material reaches the melting point in a fire environment, a molten hole will appear. The boundary of the molten hole will burn and spread, but no open flame will occur. According to my country's B "Building Materials Combustion Performance Classification Method", it is designated as a Class B flame-retardant material.
) The color, light reflection and transmittance of the membrane material should meet the requirements in the table below.
