What are the advantages of polyurethane screens

Writer: admin Time:2019-12-20 15:50 Browse:

  Polyurethane screens make full use of the properties of polyurethane elastomers and show better performance points when put into production. Today, polyurethane screen manufacturers will summarize what are the advantages of polyurethane screens.
  Polyurethane screen is not only one of the screening equipment, but also needs to have the function of transporting the screen material. During the movement, the material generates sliding friction, rolling friction, impact, wear and corrosion on the screen, which can reduce the screen. Service life, so the screen is required to be easy to remove, easy to replace, wear-resistant, corrosion resistance, impact resistance, good self-cleaning and long service life, etc., polyurethane screen can meet the above requirements.

  Advantages of polyurethane screen

  1. Long service life, good abrasion resistance and large bearing capacity.
  Because the polyurethane elastic screen uses steel wire rope as the skeleton material, plus the polyurethane itself has a very high elastic modulus, high strength to absorb impact, and high abrasion resistance, so it has high tensile strength. More than 2.5 times. Its service life is 8-10 times longer than that of ordinary metal screens, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. It is the screen material with wear resistance in the world. Polyurethane mesh production materials are polymer organic elastomers, which have good abrasion resistance, flex resistance, and large carrying capacity. The raw materials for the production of polyurethane screens have been specially treated to ensure that they will never delaminate under long-term alternating loads.
  2. High sieving rate, self-cleaning performance inside the sieve surface, no blocking of holes, high sieving rate.
  Polyurethane has strong water permeability and large cone angle (140 °), so it can prevent the adhesion of moist fine particles, so it is suitable for the screening of moist fine particles. Polyurethane screen uses imported raw materials, its elastomer and its own good relaxation performance, to avoid plugging in dynamic conditions.
  3. Wide application scope and strong industry applicability.
  Polyurethane screen industry is used in hydropower stations, building materials and other metal processing and mining industries. The sieving of various materials in the range of 0.1mm-170mm, whether it is dry or wet, does not affect the screening rate. For the dewatering and descreening in the range of 0.5m-3mm, the superiority of the polyurethane sieve surface is more fully displayed.
  4. Significant economic benefits and low total cost.
  Although polyurethane screens of the same specification (area) have higher secondary investment (approximately 2 times) than stainless steel screens, since the life of polyurethane screens is 3 to 5 times that of stainless steel screens, and less maintenance and replacement of secondary screens, the total The cost is not high and it is economical. Although the price of polyurethane rubber screen is higher than that of metal screen, if you consider the screening rate, maintenance cost, service life and other factors, you will find that the overall benefit of polyurethane screen is much better than ordinary metal screen.
  5. Good moisture resistance.
  It can work under the condition of water, and in the case of water, oil and other media, the friction coefficient between the polyurethane screen and the material is reduced, which is more conducive to sieving. Particles of limited size will not block the sieve holes and improve the screening rate. And can avoid the adhesion of moist particles, at the same time because the friction coefficient is reduced, the wear is reduced, and the service life is extended.
  6. Low noise.
  It is understood that most of the screens have a lot of noise when they are used, and in severe cases will correspond to the surrounding environment. However, the comparative polyurethane screens are different. No matter which materials and materials are sieved during the use, they will not make a lot of noise. The quiet sieving operation is their great advantage and color. As a result, polyurethane screens are very popular.

  Polyurethane sieve has self-cleaning performance, does not block holes, has high screening efficiency, and has a long service life. Because polyurethane elastic sieve uses steel wire rope as a skeleton material, plus polyurethane itself has a very high elastic modulus and high strength to absorb impact. High abrasion resistance, so it has high tensile strength, and its carrying capacity is more than 2.5 times that of rubber screen. Its service life is 8-10 times longer than that of ordinary metal screens, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. It is the screen material with good wear resistance in the world. Therefore, in the production of Longzhong vibration dewatering screen, it is strong and durable, and the screening effect is good. It can be used for a long time without replacement. For customers, it will reduce a lot of production costs.
