Advantages of polyurethane screen mesh
1. Super wear resistance, longer service life
Material properties: the wear resistance of polyurethane elastomer far exceeds that of metal (e.g. manganese steel) and traditional rubber, and its wear resistance coefficient is 3 to 5 times that of ordinary rubber, which is especially suitable for screening ores, sand and gravel and other high-hardness and high-impact materials.
Application scenarios: in coal mining, iron ore and other high-frequency screening scenarios, the service life of up to 6-12 months, significantly reducing the frequency of replacement, reducing the cost of downtime maintenance.
2. High elasticity and opening rate, high screening efficiency
Elasticity advantage: polyurethane has a strong elastic deformation ability, which can effectively absorb the impact of materials and reduce the phenomenon of clogging holes (especially for wet and sticky materials), and at the same time, it can improve the permeability rate through the high-frequency vibration.
Design of open pore rate: a variety of hole diameters can be customized according to the requirements (the smallest can be 0.075mm), the highest open pore rate of 41% (metal screen mesh is usually 25%-30%), the screening efficiency under the same area is improved by 20%-30%.
3. Corrosion and aging resistance, adapt to complex environments
Chemical stability: acid, alkali and salt corrosion resistance, not easily affected by moisture, oil and other environmental impacts, suitable for chemical industry, non-ferrous metal mining and other corrosive scenes.
Weathering resistance: stable performance in the temperature range of - 30 ℃ to 80 ℃, strong UV aging resistance, outdoor long-term use is not easy to crack.
4. Light weight and convenient installation
Lightweight design: under the same specifications, the weight of polyurethane screen mesh is only 1/3-1/2 of that of metal screen mesh, which significantly reduces the load of equipment and energy consumption.
Flexible installation: support tensioning, bolting and other installation methods, supporting rubber pads or spring damping structure, the installation time is shortened by more than 50% compared with the metal screen mesh.
5. Environmental protection and noise reduction, in line with green production
Low noise: the elastic material can reduce the impact noise during the screening process (10-15 dB lower than metal screens), improving the working environment.
Recyclability: Polyurethane material can be recycled through professional process, reducing industrial waste pollution.
