Polyurethane screen plate is a kind of mesh product produced from polyurethane as raw material. The following is a detailed product description of polyurethane screen plate.：

1. Appearance and structure

The hole-shaped designs of polyurethane screens are diverse, including various types and sizes such as slits, rectangles, circles, squares, etc., to meet different screening needs.Its surface is flat and the edges are finely treated to ensure stability and durability during use.

2. The main features

( 1 ) Good wear resistance: Polyurethane screens have extremely high wear resistance. Their wear resistance is 3 to 5 times that of steel screens and more than 5 times that of ordinary rubber screens, and they have a long service life.

( 2 ) High screening efficiency: Due to the strong water permeability of polyurethane and the large mesh cone angle (140°), it can effectively prevent the adhesion of wet fine particles, so it is suitable for the screening and grading of wet fine-grained materials.At the same time, the polyurethane screen has a self-cleaning effect and has high screening efficiency.

( 3 ) Wide range of applications: Polyurethane screens can be used in coal washing plants, coking plants, mines, power plants, dredging companies, metallurgy, petroleum, petrochemical and other industries. They are suitable for any type of vibrating screen machine and can be made by measuring machines.

( 4 ) Light weight: The polyurethane screen has a small specific gravity, which is much lighter than the steel screen of the same size, thereby reducing the load on the screen, saving power consumption, and extending the life of the screen.

( 5 ) Low noise: Polyurethane screen plate has good vibration absorption performance and sound-absorbing ability, which can reduce noise pollution and make the production site more quiet and clean.

( 6 ) Corrosion-resistant and non-flammable: Polyurethane screen plate has excellent corrosion resistance and non-flammable characteristics, ensuring its stability and safety in harsh environments.

3. The production process

The production process of polyurethane screen plate mainly includes the following steps：

( 1 ) Material selection: Choose high-quality polyurethane raw materials to ensure the performance and quality of the screen.

( 2 ) Mold design: According to customer needs and screen specifications, design high-precision molds.

( 3 ) Cutting and leveling: The polyurethane raw material is cut into a suitable size and leveled to ensure that the surface of the screen is flat and free of deformation.

( 4 ) Punching and cleaning: Punching is carried out on the screen plate to form the required hole-like structure.Then it is cleaned to remove surface oil and impurities to make the screen plate cleaner and more beautiful.

4. The application field

Polyurethane screens are widely used in hydropower stations, building materials and other metal mining industries. They are used to screen various materials in the range of 0.1mm to 170mm. Whether dry or wet, they do not affect the screening efficiency.The advantages of polyurethane screen surface are more fully demonstrated for dehydration and desulfurization screens in the range of 0.5mm 3mm.

In summary, polyurethane screens have become the preferred products in many industries for their excellent performance, wide range of applications and efficient screening efficiency.
