Advantages of polyurethane screen
Polyurethane screen has a wide range of application and research, and has stronger professional and technical applicability. Suitable for any type of vibrating screen and can be machined by measuring machines. Polyurethane screens are used in the study of hydropower stations, building materials and some other metals and mining. The screening efficiency of various materials in the range of 0.1 mm - 170 mm is not affected by dry or wet screening. The advantages of polyurethane screen in the range of 0.5m-3mm dehydration and desorting screening have been more fully reflected in the product water resistance, corrosion resistance, aging resistance, easy to replace and maintain. Polyurethane density is low (<1.32kg/m3), lighter than the metal screen surface, can reduce production costs, to meet the needs of the development of large screening machines. And can install a simple and convenient, easy to replace and maintain. This product is suitable for any type of screening machine, light weight, greatly reducing the field installation or replacement maintenance workload.
Polyurethane screen has long service life and large load management capacity. Because the polyurethane screen is made of steel wire rope as the skeleton material, the polyurethane itself has a high elastic modulus, high impact strength and high wear resistance, so it has a high tensile strength, and its carrying capacity is more than 2.5 times that of the rubber filter. Compared with ordinary metal screens, its service life continues to increase by 8-10 times, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. Is currently the world's best wear resistant screen material. Polyurethane screen production material is a polymer organic elastomer with excellent wear resistance, flexibility and large load bearing capacity. The raw material of the polyurethane screen requires a special data processing to ensure that there is no delamination under long-term alternating loads.
High screening efficiency. The screen is self-cleaning, does not plug the hole, and has high screening efficiency. Polyurethane material has strong water permeability and large cone Angle (140°), which can effectively prevent the adhesion of wet fine particles, and is suitable for the screening and grading of wet fine particles. Polyurethane screen is made of imported raw materials, its elastomer and its good relaxation properties can effectively avoid the blockage phenomenon under dynamic conditions.
The screening method has high accuracy. The production technology of polyurethane screen adopts the casting process, the aperture is accurate, the screening work is high quality, and the particle size of the material under the screen can well meet the requirements of different users.
