How to judge the quality of polyurethane screen panel？

Polyurethane screen panel is a good screen panel in the market today. It has the advantages of long service life, good self-cleaning performance, high screening efficiency, wear resistance, corrosion resistance, etc., so it is deeply loved by users and sold very well in the market. The screen panel is a vulnerable component of the dewatering screen machine, so users often choose the screen mesh carefully.

Polyurethane is favored by the screen manufacturing industry due to its excellent wear resistance, high strength, high elongation, and high elasticity as an elastic material. Polyurethane screens have gradually become a best-selling product in the screen industry. Some people may feel confused when purchasing polyurethane mesh and do not know how to judge whether the polyurethane mesh is a qualified product. In fact, when judging the quality of polyurethane mesh, only the following aspects need to be identified:

1. Appearance performance

Check whether the surface of the polyurethane screen mesh is delicate, whether the screen mesh is flat, whether the color of the polyurethane screen mesh is pure, and whether there are any broken strips, burrs, missing materials, mixed materials, tight seams, etc. The polyurethane layer of the sieve has a bright color, no impurities, no mechanical damage, and low bubble content, which is considered a good product. Otherwise, it is considered a poor product.

2. Check the opening rate

The general porosity is a direct factor affecting screening efficiency: the more pores in the polyurethane sieve, the higher the porosity, resulting in higher screening efficiency and yield. Some screen manufacturers intentionally reduce the porosity of their screens to extend their lifespan and increase their company's visibility.

3. Physical property

Polyurethane has the advantages of extremely high mechanical strength, high wear resistance, and high tensile strength. The product is resistant to water, corrosion, aging, and easy to replace and maintain. Polyurethane has a low density (1.32kg/m3) and is lighter than metal sieve surfaces, which can reduce production unit consumption. Therefore, testing from these aspects can effectively determine the mechanical performance indicators of polyurethane mesh.

4. Adhesive properties between polyurethane and metal skeleton

Polyurethane screen belongs to the composite screen in the field of screening equipment technology, mainly composed of polyurethane and steel wire rope core. The steel wire rope core serves as the skeleton of the screen, and polyurethane serves as the surface layer of the screen. Therefore, the adhesion between polyurethane and steel wire rope core becomes extremely important. The stronger the adhesion, the longer the service life and higher the strength of the screen mesh.

Conclusion

As one of the main components of screening and sorting equipment, polyurethane screen panel is also one of the vulnerable parts. High quality screen panles are highly wear-resistant, corrosion-resistant, and have a relatively long service life. Users often replace the screen panels with new ones, which can reduce production costs. However, inferior screen panels have a short service life and require frequent replacement by users, thereby increasing production costs. So when choosing PU panel you must choose a high-quality sieve plate produced by a reputable manufacturer. The above are the key points for purchasing polyurethane screen mesh, hoping to be helpful to everyone.
