low-e glass special cleaning brush Low-E glass in the production of low-e glass, because of the special nature of the material, when passing cleaning machines, cleaning brush to have higher requirements. Wire brush must be high-grade nylon filament, such as PA1010, PA612 and other advantages of low-e glass, wire diameter 0.1-0.15mm better. Because wire brush softness, elasticity, low-e glass principle acid, heat, dust can easily remove the hollow low e glass on a glass surface, and will not have cause scratches the surface. Typically, the radiation rate of 0.84 float white glass. Most online thermal polymerization emissivity 'Low-E' coated glass is between 0.35 to 0.5. Emissivity magnetron vacuum sputtering 'Low-E' coated glass in between from 0.08 to 0.15. It is noteworthy that the low emissivity directly corresponds to a low of 'u' value. Emissivity glass closer to zero, the better its insulating properties.
