Porous plum blossom tube and its preparation method

Abstract

The invention discloses a porous plum-blossom-shaped pipe, and belongs to the technical field of high-molecular materials. The raw materials comprises the following substances in parts by weight: 45-55 parts of high-density polyethylene resin powder, 18-22 parts of low-density polyethylene resin powder, 4.5-5.5 parts of high-strength glass fiber, 0.45-0.55 parts of a property modification stabilizer, and 9-11 parts of a property modification filling material. The plum-blossom-shaped pipe is relatively smooth in inner wall, cables can directly pass through the pipe without using other utensils, and time and labor are saved; the plum-blossom-shaped pipe is resistant to acids and bases, resistant to salts and alkalis, resistant to corrosion, resistant to oxidation, resistant to ageing, suitable in structure, high in usage value, long in service life, green and environment-friendly, and helps to improve the construction speed and substantially reduce the construction cost of an engineering unit.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the technical field of porous plum blossom tubes. Background technique [0002] Plum blossom tube is a kind of plum blossom-shaped communication pipe formed by PVC particles as the main material and other formulas through a unique mold, also known as honeycomb pipe. There are three types of five holes, seven holes and nine holes. It is smooth and can directly wear optical cables, which can save man-hours. Its structure is reasonable, its use value is high, and its service life is long. It is mainly used for communication cable sheathing. [0003] The length of a single commonly used ordinary pipe is generally 6 meters. During the construction process, an excavator is required to excavate the long-distance road surface, and joint welding is required during the laying of the pipe to reach the construction distance. After the laying of the pipe is completed, the soil will...

AI Technical Summary

Problems solved by technology

[0003] The length of a single commonly used ordinary pipe is generally 6 meters. During the construction process, an excavator is required to excavate the long-distance road surface, and joint welding is required during the laying of the pipe to reach the construction distance. After the laying of the pipe is completed, the soil will be backfilled. , which not only wastes time, manpower and material resources, but also increases the cost

[0004] Existing pipelines need to use other equipment when the cables pass through, and the pipelines have poor resistance to acid and alkali, salt and alkali, and corrosion; they have poor anti-oxidation and aging capabilities

[0005] Commonly used plum blossom tubes have high density due to unreasonable raw material ratio, inconvenient storage and transportation, and poor low temperature resilience
