Cold wrap


一分彩Cold-wrapped tape refers to the adhesive tape used for anti-corrosion winding. Cold-wrapped tape generally includes polyethylene (composite) type anti-corrosion tape, polypropylene reinforced fiber anti-corrosion tape, aluminum foil anti-UV anti-corrosion tape, polyethylene type 660 (modified asphalt) Adhesive tape, double-sided tape anticorrosive inner tape (This kind of tape is rarely used in China, but it is very practical and widely used abroad, and is generally used for export) and epoxy coal tar anticorrosive tape.


The composite cold-wrap tape is composed of cold-wrap tape, cold-wrap tape, cold-wrap tape and primer. The tape is coated with butyl as the main adhesive layer. The main component is polyethylene. . The inner band is the main anti-corrosion layer, also called anti-corrosion band. The outer band has high mechanical strength and plays a protective role. It is called a protective band. The adhesive layer and the inner band can form a good bond. During the construction, the surface of the steel pipe should be treated as required, then the primer should be applied, the inner tape should be wound, and then the outer tape should be wound. There is a special mastication band for mending. It is a commonly used type of cold-wrapped tape, especially the old technology and construction personnel, which are more accustomed to use, but it is also a relatively low-end anti-corrosion material product, replacing the old-generation three-oil five-cloth old-fashioned anti-corrosion process. Butyl rubber modified asphalt cold-wrapped tape The cold-wrapped tape with butyl modified asphalt that is hot-coated with base tape is a widely used and very popular pipe anticorrosive material. The base material is divided into polyethylene and reinforcing fiber. Propylene and asphalt can be tightly combined with the substrate at a certain temperature after modification to form an integrated cold-wrapped tape. These two types of polyethylene cold-wrapped tapes and polypropylene reinforced fiber cold-wrapped tapes are now called one-piece tapes, type 660 cold-wrapped tapes. This way the cold-wrapped tapes not only improve the anticorrosive performance, but also do not need to separate the inner and outer tapes. That is, it not only reduces the workload, but also reduces the anticorrosive defects caused by the combination. It is the main product of polyethylene anticorrosive pipe anticorrosive materials, especially the polypropylene reinforced fiber cold-wrapped tape is a new type of anticorrosive material for pipes, and its performance is further improved. Improved, especially the external mechanical strength, has the reputation of corrosion protection. This kind of cold-wrapped tape will gradually replace the composite cold-wrapped tape with inner and outer tapes.
