The problem of material leakage at the edge of the polyurethane screen is a very serious problem. It may cause the screened materials to be unqualified, or may lead to re-screening, which will greatly affect the economic benefits and reputation of the company. The problem of material leakage at the edge of the polyurethane screen is generally not easy to find, and by the time it is discovered, it is basically too late. The following aspects will be solved for you. The reasons for the leakage at the edge of the polyurethane screen can be said to be multi-faceted. One is that the quality of the polyurethane screen is not up to standard, the other is the installation of the polyurethane screen, and the third is maintenance. Generally speaking, it is not Except for these three situations.
1. Irregular installation
The installation problem of polyurethane screens can be said to be a commonplace. Technical personnel from production companies and screening companies basically don’t care much about the installation of polyurethane screens. They feel that they have been installed for many years and do not need to be repeated. In fact, they ignore a fundamental problem that polyurethane screens do not remain unchanged for many years. Any product is constantly improved, sometimes with only subtle differences. Through inspection, it was found that the process of installing polyurethane screens in screening companies is: when it is found that the old polyurethane screens cannot be used, first remove the fixing bolts on the screen surface, then remove the tensioning plates on both sides of the screen frame, and then use a machine to dispose of the old ones. They drag out the polyurethane screen, but they don't know that many problems lie in this dragging out. This process may seem simple, but it can easily cause uneven stress around the frame, causing damage. The correct method is to start gently and then slowly during the pulling-out phase. Take your time. When you find that the pulling-out process is difficult, find the reason before pulling out.
When installing the polyurethane screen, first remove the stones under the polyurethane screen surface and the edge of the screen frame. Before paving, pay attention to whether the screen surface is flat, whether the screen edge and the frame are tightly combined, and then tighten it. plate, and fix the screen surface bolts.
2. Maintenance
Any equipment and accessories must be maintained and inspected after a period of use, otherwise they will malfunction. New polyurethane screens generally have less failure rates, but when used for nearly 30 days, you should always check whether there are any large or small particles in the screened material. If unevenness occurs, promptly check the screen edges and tightening plate screw fixings, etc. During the screening process, pay attention to frequent inspection and listening to see if there is any abnormal sound problem, and promptly judge and deal with problems if they are found. On the contrary, it will be difficult to deal with material leakage when the polyurethane screen is damaged.
