The benefits of PE water supply pipe and its rough improvementThe benefits of PE water supply pipe and its rough improvement
With the continuous improvement of people's living standards, people pay more and more attention to health, so it is also crucial to change the water quality water supply pipe fittings. The material of pe water supply pipe is to use relatively stable polyethylene as the raw material, and it also has the characteristics of high temperature resistance and no deformation.
The length of the pe water supply pipe is about 6 meters, which is convenient for transportation, and also saves freight and reduces transportation costs. At the same time, the pe water supply pipe is divided into two types: straight pipe and coil pipe, which is used in various water supply projects. Quality and low price make people feel more at ease and comfortable.
pe water supply pipe also has cold resistance, heat resistance, corrosion resistance, wear resistance, and even in service life, it is also an excellent performance that cannot be surpassed in similar pipes. Moreover, the PE water supply pipe is a green and non-polluting pipe, and the material can be recycled, and because the pipe material will not rust, it is not only conducive to environmental protection but also beneficial to replace the ordinary iron water supply pipe.
When using the PE water supply pipe, you will find that the surface of the water supply pipe will be rough. In fact, there may be many reasons for this phenomenon. If it is made of new materials, the roughness of the surface of the pipe may be ruled out who followed the raw materials. If the roughness only occurs on a thin layer on the surface, it may be formed in the die section.
Because the heating time of the raw materials in the machine head or barrel is too long, the head and screw barrel are not clean or the temperature during processing is too high or the screw damage is more likely to produce old materials, and it is easy to form large pits or cavities during extrusion If this happens, you need to stop for about 1.5 hours, add crushed materials, if you do not start for 4 hours, you should quickly reduce the temperature to 150 to 200 degrees Celsius to reduce the degree of decomposition of raw materials.
When the raw material is wet, some small bubbles on the surface of the PE water supply pipe will form pits after setting. This kind of pits have a small tail formed by stretching in the opposite direction of extrusion. The drying process was done. When there are impurities in the raw material that are difficult to plasticize, some pitting points will also be generated. When the pitting point is relatively large, the impurities in the middle of the pitting point can be seen. At this time, it is necessary to increase the processing temperature or replace the raw material.
