Polyethylene glass fiber wound structure wall pipe and its production method

Abstract

The invention relates to a polythene glass fiber winding structure wall tube stock which is composed of an inner wall layer and an outer wall layer. The inner wall layer is characterized in that a composite material strip formed by adding a glass fiber material strip between an upper flaky polyethylene strip and a lower flaky polyethylene strip winds a roller mold, and edges of the neighboring composite strips are sequentially mutually lapped to form a continuous solid wall tube; the outer wall layer is characterized by being formed by outer protruding reinforcing ribs formed by the fact that another glass fiber material strip covering between an outer tubular polyethylene strip and an inner tubular polyethylene strip winds the outer surface of the inner wall layer, and the outer protruding reinforcing ribs spirally strides a lapping fusion joint of edges of the neighboring composite strips of the inner wall layer. The tubular pitch height of the reinforcing ribs can be guaranteed by adopting the glass fiber strips, good alkali resistance, flexibility and tensile resistance in the longitude and latitude height are achieved by the aid of fiberglass mesh fabric, the weight of the product is reduced, raw material consumption is reduced, cost of the product is low, internal stress of the tube stock is greatly reduced, consumption is reduced, and ring stiffness, ring flexibility and crack resistance are improved.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes and their processing, in particular to polyethylene glass fiber winding structure wall pipes and a production method thereof. Background technique [0002] At present, polyethylene pipes have become the second largest consumption of plastic pipes in the world after PVC, and are widely used in water supply, agricultural irrigation, gas transmission, sewage discharge, mine mortar transportation and other projects as well as oil fields, chemicals, post and telecommunications and other fields. . In many fields such as sewer pipes and drainage works in cities, the use of plastic pipes with reinforcement is increasing. There is no pressure inside the drain pipe. In order to improve the performance of resisting external pressure and impact, different forms of reinforcing ribs are set on the outer periphery of the pipe wall. There are two main types of commonly used plastic pipes with reinforcing ...
