What are the advantages of polyurethane mesh compared to ordinary metal mesh?
Polyurethane graded screen and screen panel are widely used in screening machines in metallurgy, mining, coal and other industries. They are the replacement products of steel plate punched screen, steel wire woven screen, stainless steel screen panel and rubber screen panel. Traditional mesh screens are usually made using methods such as punching, weaving, or welding, and are made of carbon steel, stainless steel, or alloy steel. The screen panel is severely impacted and worn by ores, and coupled with the high frequency of vibrating screens, the welds are prone to fatigue cracking, resulting in a short service life and frequent replacement, which seriously affects the production efficiency of vibrating screens. As a result, polyurethane screen panel with light weight, high screening efficiency, low clogging, wear resistance, impact resistance, and long service life have entered the market.
If comparing the advantages of polyurethane screen panel and metal screen mesh, they can be divided into the following points:
Due to the use of steel wire rope as the skeleton material and the high elastic modulus of polyurethane itself, which absorbs impact force with high strength and wear resistance, polyurethane screen panel has high tensile strength, and its load-bearing capacity is more than 2.5 times that of rubber mesh. Its service life is 8-10 times longer than ordinary metal screens, 3 times longer than stainless steel screens, and 3.9 times longer than natural rubber screens. It is currently the most wear-resistant screen material in the world.
The screen panel surface has self-cleaning performance inside, does not block holes, and has high screening efficiency. Due to the strong water permeability and large sieve cone angle (140 °) of polyurethane, it can effectively prevent the adhesion of wet fine particles, making it suitable for screening and grading of wet fine particles. HUATAO uses imported polyurethane raw materials, which have excellent elasticity and self relaxation properties, effectively avoiding pore blockage under dynamic conditions.
The production process of polyurethane screen panel adopts the mold casting molding process, which achieves a more uniform pore size distribution through mold molding, with a small tolerance range (such as ± 0.05mm), accurate pore size, high screening quality, and the particle size of the screened material can meet the requirements of users very well. However, metal mesh screens are prone to deformation or burrs during weaving or punching processes, resulting in significant deviations in actual aperture sizes.
Polyurethane screen panel is used in hydropower stations, building materials, and other metal mining industries. The screening efficiency of various materials within the range of 0.1mm to 170mm is not affected by dry or wet screening. The superiority of polyurethane screening surface was more fully demonstrated for dehydration and desliming within the range of 0.5-3mm. Polyurethane has a low density (1.32kg/m3) and is lighter in weight than metal screen surfaces, which can reduce production unit consumption and therefore meet the requirements of large-scale development of screening machines.
Conclusion
In summary, polyurethane screen panel has made up for many shortcomings of traditional metal mesh and has gained recognition from a wide range of users. HUATAO also continuously upgrades the production technology of polyurethane mesh, and through precise control of the production process, can meet customers' needs for different pore sizes.
