Polyurethane screens are widely used in metallurgy, mining, coal, building materials, water conservancy, road construction, and other industries, and are widely used. And the structural styles are changeable, such as inlaid mosaic, bolt connection, bead connection, screen hook connection, etc.  The following introduces the 9 major criteria for purchasing high-quality polyurethane screens.

How to choose a high-quality polyurethane screen?

1. Check if the mesh size of the polyurethane screen is uniform. High-quality polyurethane screen meshes are uniform and up to standard with tight tolerances.

2. The open porosity of the polyurethane screen. The opening rate is the most critical factor affecting screening efficiency.

3. Connection of polyurethane mesh. The connection method of the polyurethane screen directly affects the screening efficiency. Polyurethane screens are required to be tightly connected to each other without ore leakage to ensure the quality of finished products.

4. High-quality polyurethane mesh should be moderately rigid and flexible. In actual production, the polyurethane screen is required to have strong elasticity to ensure that it does not collapse during production. Polyurethane screens should have certain toughness to ensure that the screen is not easy to break.

5. Look at the appearance of the polyurethane screen. Whether the surface of the polyurethane screen is delicate, whether the screen is flat, and whether the hue is pure. Whether there are broken strips, burrs, lack of materials, mixing, tight seams, and other phenomena.

Advantages of polyurethane screen

1. Combines hardness and toughness. It still has the elongation and resilience of rubber at high hardness.

2. High strength. Tear strength, tear strength, and bearing capacity are relatively high. Impact strength and flexural strength are also very high.

3. Wear-resistant and oil-resistant. Polyurethane plate is a strong polar polymer compound.

4. Good resistance to oxygen and ozone.

5. Good vibration absorption performance, can be used for vibration reduction and buffering.

6. Radiation resistant. Polyurethane has good resistance to high-energy rays, and still has satisfactory performance under the radiation dose of 10-10 g.

7. Low-temperature resistance, and good machinability.
