What is the difference between PET sheet and PET coil production?
2023-12-28 16:45PET production process:
Raw material mixing - mixing - feeding - crystallization - feeding - drying - feeding - extruding - modulating - three mix shaping - auxiliary traction - cutting - cutting or winding - measuring or testing - packaging - labeling - loading - storage
The difference between PET sheet and PET coil:
PET sheet and PET coil are required to meet the quality requirements of the order. There is no difference in surface, size and thickness.
The main differences are as follows:
1. The focus of sheet production is flat; We'll pay attention to the uniform thickness and the degree of winding tightness. Otherwise, when the product is used, the surface will have convex and convex situation, which is also a bad situation.
2. Except meeting the requirements of the order, the sheet size must also be measured and compared with the diagonal. The general requirements can not be different win more than 2mm;
As long as the width meets the requirements, the coil hasn't got the diagonal requirements. But it must be rolled neatly and there is no abnormal appearance of "flanged edge".
3. For sheet production, we must also pay attention to the production of glossy sheet. Because glossy sheet is easy to stick, it will possibly cause the sheets too sticky. At present there is a way to solve the problem, one is to add internal slip agent, you can also use silicone oil to solve the adhesion problem.
