What is the elasticity ratio of the sieve plate of the flaccid sieve, and how much pressure is applicable!
The opening rate of the polyurethane sieve plate of the flaccid sieve. The opening rate is an immediate factor that harms the screening power: the more the total number of round-hole screens of the polyurethane screen, the higher the opening rate, the higher the screening power and production capacity. See whether the round hole screen is symmetrical: the polyurethane sieves round hole screen is symmetrical and in accordance with the specifications, and the overall plan for public service is small. Possess excellent mechanical processing and manufacturing performance.
Resistance to radiation sources. The performance of the flaccid screen polyurethane material is very good against higher energy radiation, and it still has satisfactory application performance under the personal radiation dose of 10-10 Ge. Possess excellent ultra-low temperature performance. Polyurethane screens must be rigid and flexible: the polyurethane screens must have strong ductility in the production of practical activities to ensure that the waist is not stepped in the production; the polyurethane screens must have a certain degree of patience to ensure that the screens are not easy to break.
Spreader screen polyurethane sieve panels are commonly used in metallurgical industry, mining, coal, decorative building materials, water conservancy projects, road expansion, etc. Good grate panels endanger their working power. So how to choose a good grate board? Acid and alkali resistance. The flaccid sieve polyurethane plate is a kind of strong optically active polymer material chemical substance, which has little affinity with non-mineral oil, and is almost free from corrosion in light fuel oil and mechanical lubricant.
durable. Its wear resistance is very good, generally in the range of 0.01-0.10(cm3)/1.61km, which is about 3-5 times that of rubber. The appearance of the polyurethane sieve plate of the flaccid screen: whether the surface of the outer polyurethane sieve is exquisite, whether the sieve can be flattened, and whether the color of the polyurethane sieve is simple, there are broken strips, burrs, insufficient material, wrong material, Phenomena such as close seams. The polyurethane sieve plate has good water resistance and can work under the standard of water as a substance. And under the condition of water, oil and other substances, the friction resistance between polyurethane and raw materials is reduced, which is more conducive to screen penetration, forward screening power, and It can prevent the adhesion of wet particles, for one reason the friction index is reduced, and the damage is reduced.
