mpvc power pipe

Abstract

The invention belongs to the technical field of pipes, in particular to an MPVC power pipe. The invention divides the inner cylindrical part and the outer cylindrical part into several computer storage rooms through two fixed plates and a plurality of movable plates in the middle, which not only meets the standard requirements for neat laying of cables, but also realizes the division of the internal space of the power pipe, thereby The cables can be placed separately to avoid crossing and entanglement of the cables, avoiding the abrasion between the cable protective sleeves, and improving the toughness of the power tube; the surface of the card groove on the inner wall of the outer cylinder is smooth, and the cable , not only to improve the rigidity of the body, but also to protect the cable, avoiding damage to the cable when pulling.

Description

technical field [0001] The invention belongs to the technical field of pipes, in particular to an MPVC power pipe. Background technique [0002] The main component of PVC is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC pipe hard polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc. Extruded by hot pressing, it is the first plastic pipe to be developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC-U monomer and additives, Only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compr...

The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC pipe hard polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc. Extruded by hot pressing, it is the first plastic pipe to be developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC-U monomer and additives, Only suitable for water supply systems where the delivery temperature does not exceed 45°C, plastic pipes are used for drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, slurries, gases, compressed air and vacuum systems

[0003] There are still some shortcomings in the existing MPVC pipes. The strength of the pipe body is low, which shortens the service life of the MPVC pipe. When it is used as a power pipe, there are many cables passing through it. It is not conducive to find the target cable when performing maintenance work on the cable, and it is easy to cause damage to the surface of the cable when pulling the cable
