Polyurethane screens are widely used. When installing polyurethane screens, in addition to tensioning the screen surface, attention should be paid to the device nut to fix the screen surface. So, what are the problems when installing polyurethane screens and how to install polyurethane screens? Let's understand together with the polyurethane screen manufacturer:
1. When installing, the screen must be tightened, because the tightness of the screen is an important factor affecting the screening efficiency.
2. When cutting, the screen width should be the same as the net frame, and the length must be 50~70mm longer than the net frame.
3. Be sure to choose a screen with a larger wire diameter, because the installation of the linear vibrating screen is relatively cumbersome.
4. When installing a clear net pinball, you must pay attention to the difficulty of screening the material and the number of meshes.
5. If the specific gravity of the material is large or the mesh number of the screen is high, a suitable support mesh should be added under the polyurethane screen. The purpose is to support, reduce the pressure of the material on the screen, and extend its use. life.
6. After the net frame is installed on the box body as required, remember to extend the growing screen into the corresponding outlet to avoid mixing.
7. When installing the pressure plate, be sure to pay attention to its flatness, and line it with a strong elastic sponge sealing tape to evenly lock it.
8. After the installation is completed, a small amount of materials should be used to test the cloth and screening conditions of the screen.
Installation is usually not paid attention to by people. The screen surface should be tight during installation. Otherwise, it is easy to impact the screen surface and damage it when the stone is lowered.
When installing the polyurethane screen, pay attention to adding polyurethane strips on both sides of the screen surface to fix it. In order to save costs, waste old tapes are often used instead of polyurethane strips.
Whether the sieves are level or not depends on whether the hue of the polyurethane sieves is simple and whether there are signs of broken strips, burrs, lack of material, mixing, tight seams, etc.
The bottom-up boards are overlapped in a straight line, and the boards and boards overlap in a whole. The polyurethane screen has good moisture resistance. It can be operated under the condition of water as the medium. The friction coefficient between the polyurethane and the material is reduced, which is conducive to screen penetration and forward screening power, and can avoid the adhesion of wet particles and reduce wear. Pay attention to the above problems when installing polyurethane screen.
The shape of the polyurethane screen plate is rectangular, square, round, narrow pore shape, etc., and is widely used in Hubei, Hunan, Shandong, Linzhi, Tibet, Qinghai vibrating screen metallurgy (iron ore, limestone, fluorite, cooling Blast furnace slag, coke and other raw materials), non-ferrous metals, gold, coal, chemicals, building materials and hydropower engineering, abrasive waste treatment, quarries and other industries for washing, screening, grading, deslagging, desliming, dehydration and other industries.
Polyurethane screen mesh structure is divided into four types: 1) Inlaid type 2) Bolt connection 3) Bead connection 4) Screen hook connection
Usage: According to the different raw materials used, there can be products with different properties, generally polyester type and polyether type. It can be used to make plastics, rubber, fibers, rigid and flexible foams, adhesives and coatings.
