Description

Technical Field

[0001] The utility model relates to the technical field of PVC wire pipes, in particular to an acid and alkali resistant PVC wire pipe. Background Art

[0002] PVC wire pipe, also known as hardened polyvinyl chloride pipe, is a straight conduit made of polyvinyl chloride resin as the main raw material, with other additives added and extruded for the protection of wires and cables in industrial and construction projects below 2000V. PVC wire pipe is widely used in home interior decoration and construction engineering water and electricity installation for pipe protection due to its flame retardant, insulating, easy installation and long service life. The characteristics of PVC wire pipe are as follows: Lightweight: PVC wire pipe has a low density, so it is relatively light and easy to carry and install. Good insulation performance: PVC wire pipe can effectively protect wires and prevent wires from contacting other objects during transportation and installation, which may cause accidents. Good corrosion resistance: PVC wire pipe can work in harsh environments and is not easily corroded by the outside world. Good flame retardant performance: The material inside PVC wire pipe has flame retardant properties Better, not easy to burn even in high temperature environment, can effectively protect wire equipment, easy construction: PVC wire pipe is relatively easy to install, requires fewer tools, and can be completed by simply making the correct joints. In addition, PVC wire pipe also has the characteristics of strong pressure resistance. The high impact resistant medium-sized pipe series can withstand strong pressure, so it can be laid in concrete without fear of rupture under pressure. When manufacturing PVC wire pipe, the selection of raw materials and production process are the key. It is necessary to select suitable PVC resin and add additives such as stabilizers, lubricants and fillers. After that, it is made into PVC wire pipe through steps such as hot mixing, extrusion molding, cooling and shaping, and cutting and trimming. In general, PVC wire pipe has broad application prospects in the field of wire and cable protection. With the continuous advancement of technology and the increase in market demand, its performance and application range will be further improved and expanded.

[0003] As shown in the patent application number 201320284001.4 on the China Patent Network, the utility model provides a PVC wire conduit having a hollow tube body and a partition plate provided in the tube body along the tube diameter direction. At least one side of the partition plate is provided on the inner wall of the tube body. The PVC wire conduit of the utility model separates different types of wires by providing a partition plate in the tube body, making it easy to identify and replace the wires. The utility model has no additional protective mechanism, and the number of wire harness categories is too small, resulting in a significant reduction in its service life when used in an environment with high pH and too few types of wire harnesses for classification.

As a result, when PVC wire pipes are used in environments with high pH, ​​their lifespan is greatly reduced and the wire harnesses cannot be classified.

[0005] Therefore, it is necessary to redesign and modify the PVC conduit to effectively prevent its weak acid and alkali resistance and the phenomenon of being unable to be classified. Utility Model Content
