As an important part of chemical building materials, plastic pipe is widely accepted by customers for its superior performance, sanitation, environmental protection and low consumption. It mainly includes UPVC drainage pipe, UPVC water supply pipe, aluminum-plastic composite pipe, polyethylene (PE). These are the water pipes. The pipe production line consists of a control system, an extruder, a head, a fixed cooling system, a tractor, a planetary cutting device and a turning frame. There are two extruders in each pipe production line. The main one extruder uses a strong conveying bushing and a high-efficiency screw, and the other smaller extruder is used to extrude the marking line. When the plastic pipe production line fails, the surface of the plastic pipe will be rough, the internal vibration ring will appear, and there will be no vacuum. Therefore, it is necessary to eliminate the failure of the plastic pipe production line in time to improve the product quality.
How to identify the quality of PVC pipe
(1) Look at the surface finish and whiteness first.
(2) Take the sample to fall, the person who is easy to break is generally a high-calcium product. Of course, it is ok to meet your requirements.
(3) Take the sample with the foot on the side of the pipe to see if it can crack, or the elongation at break after cracking.
(4) The weather resistance is very troublesome. The most direct way is to take a few days to get the high temperature and high light, to see the surface change rate, but it is a waste of time. Mainly look at the first three items just fine.
