The polyurethane flexible sieve plate has fully used the remarkable wear-resisting property, high strength in broad hardness range, high elongation, high elasticity, good absorption of shock as well as oil resistance, low temperature resistance, heat and aging resistance, radiation resistance, electric insulation of the polyurethane elastomer; besides, it has a reasonable mesh structure and installation structural design.
So the polyurethane flexible sieve plate possesses the following features:
The wear resistance property is good, the service life is long, its wear resistance is 3~5 times to steeliness sieve plate, more than 5 times to ordinary rubber sieve plate.
The maintenance service work is small, the polyurethane sieve plate is not easy to damage, the service life is long, therefore, it may reduce the maintenance service quantity and the loss of production suspension and overhaul.
The total cost is low although the investment of the same specification (area) polyurethane sieve plate is more expensive than stainless steel sieve plate (approximately 2 times). The service life of polyurethane sieve plate is 3~5 times than the stainless steel sieve plate, moreover, the maintenance and the replacement are few, therefore, the total cost is not high, it is also very worthwhile in economy.
The moisture resistance property is good; it may work in the water. When in oil and water, the friction coefficient between polyurethane and the material reduces, which is better for thorough sieve and enhances the efficiency sieves and avoids the adhesion of the moist particle, meanwhile, because the friction coefficient and abrasion reduce, the service life longer.
It is anti-corrosive, uneasy to flame, non-toxic and tasteless.
The mesh design is reasonable, the sieve plate fabrication technology is unique, and as a result, extreme dimension pellet cannot block the mesh.
Good vibration absorption, noise elimination ability. It may reduce noise and cause the thing in sieve plate not easy to shatter in the vibration process.
Because the second time vibration characteristic of the polyurethane, polyurethane sieve plate has the cleaning function, therefore, the screening efficiency is high.
The energy conservation falls, the polyurethane proportion is small, it is much lighter than the similar size steel sieves, thus, it reduces the sieve machine load, saves the electricity consumption, and may lengthen the sieve machine life.
