1, 3PE anti-corrosion mainly used raw materials for polyethylene, polypropylene.
2,Epoxy resin anti-corrosion mainly applies epoxy resin composite coating, phenolic epoxy coating, polymer composite materials.
3, Epoxy coal asphalt anti-corrosion is mainly applied to asphalt anti-corrosion paint and polypropylene non-woven fabric.
4,Cement mortar is mainly applied to cement mortar anti-corrosion.
5, cold wrapping tape refers to the use of adhesive tape for anti-corrosion winding, cold wrapping tape generally includes polyethylene (composite) type anticorrosive tape, polypropylene fiber reinforced anticorrosive tape, aluminum foil UV anticorrosive tape, polyethylene 660 (modified bitumen) tape, double-sided adhesive tape anticorrosive tape (this tape in the domestic use of very little, but is very practical in foreign countries is very extensive, generally used for export) and epoxy coal asphalt anticorrosive tape. Executive standard SY/T 0414-98 and SY/T0447-96.
6, anticorrosive steel pipe filler generally use heat shrinkable tape
It is designed for the anticorrosion of welded joints of buried and overhead steel pipelines and the thermal insulation of insulated pipelines. It is made of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive composite, special sealing hot melt adhesive and polyolefin substrate, steel pipe surface and solid epoxy coating can form a good bond.
The characteristics of cold wrapping tape and 3PE heat shrinkable tape are: it is suitable for various materials main body anti-corrosion layer pipeline, while the other way is suitable for the same or close to the material of the main body anti-corrosion layer pipeline.
