PVC pipe is a common item in daily life, but once it is used, the foaming of the PVC pipe wall will have a certain influence on its thickness, which will cause the thinning of the pipe wall to affect the use. As a professional PVC manufacturer, I will explain to you the causes and countermeasures of the uneven thickness of PVC pipes.
The uneven thickness of the wall of the PVC pipe is generally caused by the unstable use speed of the tractor during production. Specifically, it is divided into the following cases:
1, the die, the core rod are not the same, need to adjust the mold;
2, the temperature of the machine head is uneven, the discharge speed is fast, need to check the heating ring;
3, the speed of traction is not stable, need to check and repair the tractor;
4. The vacuum degree of the vacuum tank fluctuates. It is necessary to check the vacuum pump and its pipeline. There are many types of PVC pipes, and there are certain gaps in size and specifications. However, there are standards. Take the PVC pipe for it. The thickness is based on the reference.
The reason for the occurrence of foaming on the pipe wall may be that the raw material is too moist, which needs to be dried to solve the problem; in addition, the vacuum at the vacuum vent hole may be too low or blockage may occur, and the working condition of the pump needs to be checked; It is possible that the temperature of the handpiece is too high and needs to be solved by lowering the temperature.
The reason for the uneven foaming and thickness of PVC pipe wall is mainly the problems in raw materials and production.
