Polyurethane tile shell production process: 1, Charge 2, 3 extrusion die 4, cooling 5, traction 6, the inner surface 7 corona treatment, cutting 8, 9 inspection, finished explain A. Polyethylene pipes easy to aging, such as open-air tarpaulin and other objects appropriate to cover storage, dumps should stay away from high heat and ignition sources, made insulation, the prohibition of exposure, quenched, or polyethylene pipe easy to crack, affect product performance and service life. B. Transport and wearing a tube process, should avoid rough handling, hook too small, tough, too hard, otherwise easily lead to polyethylene pipe broke, scratched or torn. C. adjustable pipe wall thickness, thickness, color according to user requirements, due to the different pipe wall thickness, insulation thickness of about a few, should calculate the actual thickness. D. supporting the bracket and pipe, plastic plugs, two flanges, welding, torch, thermal belt complete. E. table tolerance is based CJ / 114-2000 industry standards. The formula is: when the outer diameter ≤400mm, and upper and lower deviation = 0.1 × the nominal wall thickness of +0.2 outer diameter ≥400mm buried pipe insulation applications: the upper and lower deviations and = 0.15 × nominal wall thickness +0.2 polyurethane tile shell The thermal conductivity is the lowest of rigid polyurethane tile shell in the insulation material, thus enabling to minimize heat loss material. Waterproof, corrosion-resistant old: Because closed-cell polyurethane foam rate of more than 92 polyurethane tile manufacturers, so the manufacturers of polyurethane tile shell, polyurethane foam as insulation buried pipe insulation can not only play a role, but also effectively prevent water, moisture and many other corrosive liquids, gas penetration, prevent growth of microorganisms and the development of applicability of polyurethane foam. PU corrugated sandwich panels, new Albert corrosion insulation works (Certified, Chongqing polyurethane tile provided by the County of new anti-corrosion insulation Engineering Limited Albert.
