As users, when we use “Polyurethane Screen”, we will inevitably encounter some problems, and these problems may affect the service life of the screen. So what problems and factors will affect the service life of the screen? Woolen cloth?
1. The impact of improper use on the life of the polyurethane screen.
After selecting a suitable polyurethane screen, it should be used rationally to maximize the performance of the polyurethane screen and extend its service life. But many users often ignore this point when using polyurethane screens.
For example, a tensioned screen can easily be loosened by large pieces of material during use, and the fastening bolts need to be rotated regularly. At the same time, there is also an inlet design to ensure that the material is not placed perpendicular to the screen surface. The feeding direction should be inclined along the logistics direction, and the feeding height should not exceed 400mm to prevent damage to the screen caused by excessive impact.
2. Improper processing technology will also affect the service life of the polyurethane screen.
If the raw materials of the polyurethane screen are the same, the main factor affecting its quality is the processing technology. The polyurethane screen must be processed with a suitable mold and skeleton before pouring.
The surface temperature and oil stains of the skeleton should be treated accordingly. Improper treatment of surface oil stains will affect adhesion. The skeleton and polyurethane screen will easily fall off. Unreasonable temperature control will cause bubbles and burnout during the injection molding process, which will affect the service life of the polyurethane screen.
