Winding method of polypropylene anti-corrosion tape
Release time:
2022-05-19
Everyone should be familiar with polypropylene anti-corrosion tape. The product uses butyl rubber modified asphalt as the anti-corrosion rubber layer, and the tape operation is relatively simple. Because of this characteristic, it is widely used in the industry, so, let's learn about the winding method of polypropylene anticorrosive tape!
Everyone should be familiar with polypropylene anti-corrosion tape. The product uses butyl rubber modified asphalt as the anti-corrosion rubber layer, and the tape operation is relatively simple. Because of this characteristic, it is widely used in the industry, so, let's learn about the winding method of polypropylene anticorrosive tape!
1, first to apply primer. When we use polypropylene anti-corrosion tape to coat the primer, we should use the matching primer. When stirring the primer, be sure to stir evenly before use. After coating, the tape can be wrapped in about 10 minutes.
2. Surface treatment work: The surface treatment work is mainly to remove rust, welding slag and pollutants from the tape. We must ensure that the polypropylene anti-corrosion tape is clean and dry during the use of the tape.
3. Backfilling in the ditch: As we all know, polypropylene anti-corrosion tape is subjected to quality inspection after treatment, but after the quality inspection is qualified, the backfilling in the ditch can be carried out. When backfilling the trench, it is necessary to pay attention to the integrity of the tape.
Polypropylene anti-corrosion tape has a wide range of specifications. Below are several commonly used anti-corrosion tape. Including polyethylene anticorrosive tape and polypropylene anticorrosive tape, which are divided into thin glue type polyethylene anticorrosive tape and thick glue type polyethylene anticorrosive tape according to the thickness.
Polypropylene anti-corrosion tape thickness of 0.4~0.8mm, the main advantage is that the substrate and the adhesive layer affinity is strong, storage construction can not degumming layer. The thickness of thick rubber type polyethylene anticorrosive tape is 1.0~1.8mm. The main advantages are thick backing material, high strength, thick adhesive layer, strong viscosity, non-foaming elasticity and so on.
The thickness of polypropylene anti-corrosion tape is 1.0~1.8mm. The main advantage is that the special substrate can withstand tensile indentation and creep damage caused by soil stress.
Polypropylene anti-corrosion tape, also known as polypropylene, is a new type of non-hazardous environmentally friendly anti-corrosion material. It is a unique modified polypropylene mesh reinforced knitted fiber geotextile. It is modified with butyl rubber and polyisobutylene. The rubber layer is made of high-grade petroleum asphalt. The substrate has the characteristics of effective resistance to soil stress creep damage, simple construction, impact resistance, aging resistance, tensile resistance, UV resistance, and high bonding strength. The aging test proves that the corrosion resistance life is more than 50 years. It is a good choice in the cold belt of anti-corrosion construction, and it is also an economic choice in anti-corrosion construction.
It is widely used in oil, natural gas, chemical industry, urban construction water supply and drainage, oil and gas transportation steel pipeline and steel buried storage tank body external anti-corrosion and old anti-corrosion layer repair project.
The above introduction is the winding method of polypropylene anti-corrosion tape. If you need to know more, please feel free to contact us!
