| POLYPROPYLENE ADHESIVE TAPE【PPD】 |
|
PED/PPD with a series of pipeline corrosion products for underground and overhead weld steel pipe, the overall pipeline corrosion and thermal insulation, the overall preservation and design. It is sealed by the hot-melt adhesive polyolefin composite substrate and made of special, special sealing hot melt and polyolefin substrate and the surface and solid epoxy coating can form a good bond. Pipeline corrosion in the construction zone, while the substrate winding in the radial, internal composite layer and the end of plastic bonded together tightly, and the substrate form together into a solid pipeline corrosion body, has excellent resistance to wear, corrosion resistance, impact resistance and good UV resistance and aging properties of light.
PED/PPD pipeline corrosion and adhesive must be used simultaneously with, the construction can be manual, mechanical construction requirements of the corrosion with a hand-pull rather, there can be folded to prevent the product appears in the middle bubble wrapped up after the loss caused by product. |
