Material leakage from the edges of polyurethane screens is a very serious problem. It may cause the screened materials to be unqualified, and in serious cases it may be re-screened, which will have a great impact on the economic interests and reputation of the company.

What is the reason for material leakage from the edge of polyurethane screen?

There are many reasons for polyurethane screen side leakage: one is that the quality of the polyurethane screen is not up to standard, the other is the installation problem of the polyurethane screen, and the third is maintenance problems. Generally speaking, there are no more than three situations.

1. Irregular installation

The installation of polyurethane screens can be said to be a common thing, but often because it is installed frequently, they basically don’t care much about the installation details. They felt they had installed it for many years and there was no need to repeat it. In fact, they ignore the most fundamental problem. Polyurethane screens are not always the same. With the advancement of science and technology and the development of society, various products are constantly improving, and polyurethane screens are no exception. Although there are no major changes, there are some subtle differences.

The investigation results show that the screening company has a poly screen setting process, and when the old polyurethane screen cannot be used, first remove the fixing bolts on the screen surface, and then understand the cutting machines of the tension plates on both sides. To remove the screen frame and old stuff, use a machine, they don’t know that pulling out the polyurethane screen can cause a lot of problems. This process seems simple, but it creates uneven forces around the frame that can cause damage. The correct way is to start lightly and go slowly. If you find it difficult to pull out, find the reason and replace it.

When installing the polyurethane screen, remove the stone on the surface of the polyurethane screen and under the edge of the screen frame. When laying, pay attention to whether the surface of the picture is flat and whether the edge of the picture and the frame are firmly combined. Then tighten the tensioning plate and fix it with bolts.
