Excellent corrosion resistance of polypropylene cold-wound tape

Release date:2017-08-11 Author: Click:

Everyone has a certain understanding of the tape. Our company is a manufacturer of anticorrosive tapes. It has high cost performance and long tape life. What are the excellent corrosion resistance of polypropylene cold-wound tape? Please see the following introduction: Polypropylene anticorrosive tape

    1. Polypropylene cold-wound tape and modified butyl rubber itself have excellent water resistance and oxidation resistance;

一分彩    2. The polypropylene cold-wound tape has sufficient adhesion with the steel pipe (20-30N / cm), which can effectively prevent water from penetrating into the surface of the steel pipe. It can maintain high bonding strength after being wound or buried in the field for many years.

    3, polypropylene cold-wound tape has good extensibility. It can maintain its extensibility and flexibility over a wide temperature range. The measured elongation is usually 150 ~ 400%. The adhesive tape can be wound at a temperature of -34 ° C and can be used for a long time at -40 ° C. Its brittleness temperature is -7 ° C, and the brittleness temperature of petroleum asphalt is -5 ° C.

一分彩    4. Cold-wound polypropylene has sufficient strength to resist mechanical stress during pipeline loading and unloading and resistance to soil stress after burying. Due to the smooth surface, the pipe and the coating will not fall off when the pipe and soil are displaced after burying.

    5, polypropylene cold-wrapped anticorrosive layer has better anti-cathode peeling performance. Many adhesive tape anticorrosive pipelines have reliable protection potentials and stable protection currents, indicating that they have a good ability to adapt to cathodic protection currents.

    6, polypropylene cold-wound with high insulation and low moisture absorption. The coating resistivity is above 1 × 1012Ω.m, and the moisture absorption is <0.02%. Its breakdown voltage is 40kv / mm, which is twice that of asphalt; coal tar enamel paint has a water absorption rate that is twice that of adhesive tape, and petroleum asphalt has a water absorption rate that is six times that of adhesive tape.

    Polypropylene adhesive tape is a new type of environmentally friendly material, mainly using butyl rubber modified asphalt as the anti-corrosion layer, and the substrate is a unique modified polypropylene woven fiber cloth. Let ’s take a look at polypropylene together. Application range of adhesive tape:

    1. Polypropylene adhesive tape can be used for air-tightness and waterproofing of the joints of color profiled boards, and also for air-tightness of joints in sunlight panel projects.

一分彩    2. Polypropylene adhesive tape can also be used for roof waterproofing of new construction projects and waterproofing of structural construction joints.

一分彩    3. Adhesive tape can be used for composite aluminum foil butyl tape suitable for waterproof sealing of various civil roofs, color steel, etc. under sunlight.

    4. There is also an adhesive tape that can be used for sealing and waterproofing the construction joints of subway tunnel structures in municipal engineering and for waterproofing and sealing where they meet in the construction of steel structures. Polypropylene anticorrosive tape
