High quality phenolic paper laminated sheet board tube requires highly technical processing. The quality of processing technology is directly related to the quality of products. Now I will tell you what problems will appear in the phenolic paper laminated sheet board tube processing? We can try our best to avoid the occurrence of problems so as to improve the quality.

Problem 1: Bubbling

If the phenolic paper laminated sheet board and the substrate is not sufficiently combined during processing, so that the air can enter. Then the finished phenolic sheet will have bubble, affect the flatness of phenolic sheet, and more seriously, the phenolic sheet will appear short circuit.

Problem 2: Irregular concave

To put it bluntly, it is that the phenolic sheet surface has irregular concave. This convex phenomenon can be generally divided into bright and the rough concave. The former is caused mainly by the pressing of a harder substance on the surface, while the latter is caused mainly by the pressing of fibres on the surface.

Problem 3: Layering

Layering has a big effect on the appearance of the phenolic paper laminated sheet board or tube and is a great discount on the quality of the product. It may be caused by the amount and uniformity of the epoxy resin applied, the applied temperature, the moderation of the working environment, etc.

Problem 4: Burr

This problem can be caused by a lot of factors, which may be caused by incomplete cut, or the second cut. It could be the size of the hole is not right.

Problem 5: The oxidation of the phenolic paper laminated sheet board

Although oxidation does not affect the performance of the phenolic board, but large oxidation is not allowed by many high-end electronic and electrical products. The factors that cause the plate oxidizing are mainly that the storage environment humidity is too big, and the storage time is too long. Others are caused by sweat from operators' hands sticking to phenolic sheet surface through gloves.

Problem 6: Phenolic paper board locking

Sometimes because of the speed of processing, or the machine itself, the phenolic paper board often locks. So when the phenolic paper laminated sheet board or tube is processed, there must be special person to keep watch.

So that's part of the problem when processing phenolic paper laminated sheet board. If you have any more questions, welcome to leave us a message. Let's make progress together.
