The polyurethane screen mesh is beautiful in appearance, bright in color, light in weight, high in mechanical strength, heat insulation, sound insulation, corrosion resistance and weather resistance, without secondary decoration. All kinds of colors. The tensile strength and tearing strength are high, the wear resistance is good, and the resilience is good. The compression technology can reduce the deformation of the permanent basic structure, and the service life of one is long. It has strong adhesion with the metal material matrix, is not easy to delaminate and shed, and has high surface finish and stable size for vibrating screen.
The high-strength composite metal wire mesh belongs to the technical field of screening equipment, which is used to solve the problems of low strength and short service life of ordinary metal wire mesh. The mesh of the invention is metal mesh, the mesh is polyurethane screen mesh, the polyurethane mesh is located below the metal mesh, and the mesh is in the form of sectional mesh. The warp and weft poles are composed of steel wire rope core and polyurethane surface layer structure. The utility model has the advantages that it is different from the ordinary metal screen .
The full name of polyurethane screen mesh is polyurethane, which can produce formate. It is the general name of macromolecular organic binding compounds containing a large amount of Chinese data on the main chain and repeatedly using a carbamate group (NHCOO). It is composed of an organic diisocyanate or polyisocyanate and a dihydroxy or polyhydroxy compound obtained by addition polymerization.
As a kind of macromolecule, polyurethane can not only produce formic acid from carbamate, but also use ether, ester, urea, biuret, carbamate and other groups. According to the raw materials used, there can be different enterprise products, usually polyester and polyether. It can be used to produce hard and soft foam materials, adhesives and coatings for engineering plastics, rubber, fiber and plastics
Preparation source: polymer molecular compound formed by the main action of binary or multi-component isocyanate and binary or multi-component hydroxyl compound.
According to the structure of polyurethane screen, there are four types: 1. inlaid type. 2. Bolt connection. 3. Bar connection. 4. Screen hook connection
As a bulk material, it can be used in fine screen and dry screen. It can also be directly used to treat some corrosive materials for grading.
polyurethane screen mesh can be divided into relaxation screen, water passing screen, high-frequency screen, high-frequency dehydration screen, mosaic skeleton screen, etc. according to different uses.
- Excellent moistureproof performance. It works as a medium in the presence of water. At the same time, the friction coefficient is reduced to reduce wear and prolong service life.
- Corrosion resistant, nonflammable, non-toxic and tasteless.
