Problems solved by technology
Among them, PVC resin is a recyclable resource. Therefore, many manufacturers prefer to use recycled PVC resin as raw materials to reduce production costs when producing PVC water pipes. However, recycled PVC resin not only has strength, toughness, corrosion resistance, and heat resistance. The physical and chemical properties are very poor, and its color is dark, the appearance is rough, and the service life is short
However, if brand-new PVC resin is used as the raw material for making PVC water pipes, even if the physical and chemical properties of the utensils are improved, the production cost is too high, and it is not conducive to environmental protection and energy saving.
[0003] In addition, due to the influence of cold weather and other factors, the peak period of PVC water pipe bursting and damage is in winter. The cold weather makes PVC water pipes more hard and brittle, and the water in PVC water pipes freezes quickly after being frozen. Expansion, causing the PVC water pipe to be unable to withstand excessive deformation and rupture, ending the service life in advance, causing unnecessary waste

Embodiment Construction
[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.
[0029] refer to figure 1 , figure 2 , image 3 , the PVC water pipe 11 that is provided with the organic fiber reinforcement layer comprises a PVC water pipe 11, the PVC water pipe 11 comprises an inner core layer 22, an outer layer 21, an inner layer 23, and an inner layer is arranged between the outer layer 21 and the inner layer 23. The core layer 22; the raw material of the inner core layer 22 is a mixed material formed by mixing PVC resin and organic fiber. Since the PVC water pipe 11 of the present invention contains organic fabric fibers in its inner core layer 22, even if the PVC resin is recycled PVC resin, the strength, toughness and heat resistance of the inner core layer 22 will not be affected. Organic fabric fibers make up for the p...

Abstract
The invention relates to the field of pipelines, in particular to a PVC (polyvinyl chloride) water pipe with an organic fiber reinforced layer. The PVC water pipe with the organic fiber reinforced layer comprises a PVC water pipe body including a core layer, an outer layer and an inner layer, and the core layer is arranged between the outer layer and the inner layer and is made of mixed materials formed by mixing PVC resin with organic fibers. By the aid of the technical scheme, the organic textile fibers are added into the PVC water pipe to improve integral pressure-resistant, shearing-resistant and anti-cracking capabilities of the water pipe, so that the water pipe is firmer and more reliable. A heating pipe further arranged on the PVC water pipe can guarantee that water in the PVC water pipe cannot be frozen due to low temperature, so that possibility of freezing and bursting of the PVC water pipe is decreased.
Description
technical field [0001] The invention relates to the field of pipelines, in particular to a PVC water pipe. Background technique [0002] The improvement of urban life quality is inseparable from the development of urban water systems. At present, most of the common water pipes and drainage pipes on the market are PVC water pipes, and the main materials for making PVC water pipes are mainly composed of PVC resin and calcium carbonate. Among them, PVC resin is a recyclable resource. Therefore, many manufacturers prefer to use recycled PVC resin as raw materials to reduce production costs when producing PVC water pipes. However, recycled PVC resin not only has strength, toughness, corrosion resistance, and heat resistance. The physical and chemical properties are very poor, and its color is dark, the appearance is rough, and the service life is short. But if brand-new PVC resin is used as the raw material for making PVC water pipes, even if the physical and chemical properties...
