According to the "China Polyurethane Screen Panel Market Research and Investment Strategy Report (2020 Edition)" released by Limu Information Consulting, the polyurethane screen (net) is composed of polyurethane materials and metal materials as the framework or made of pure polyurethane. The product has The characteristics of the polyurethane material itself: good resilience, high tensile strength, high tear strength, wide range of hardness, etc. The prepared polyurethane screen has good wear resistance, long service life and low maintenance cost compared with other system screens. , Good vibration absorption, strong silencing ability. Due to the superior elasticity of the polyurethane material, the screened material has the characteristics of secondary vibration, the polyurethane screen has a self-cleaning effect, and the screening efficiency is high. Due to the low density of the polyurethane material, the weight of the steel screen is much lighter than that of the steel screen, which reduces the load of the screen machine, saves electricity, and also extends the service life of the screen machine.
At present, there are many sieve plate manufacturers in my country, and the scales vary greatly. The total technological content is not high, the homogeneity is serious, and the low-level competition is fierce, but there are not many high-end products with novel structure, durable materials and good screening effects. At the same time, in the production process of sieve plates, the processing equipment level of each manufacturer varies greatly.
With the rapid development of the production of polyurethane sieve plates and the rapid development of scale, the production method must also be automated. The realization of production process optimization, stable operation of the equipment system, excellent operator quality, and controllable intermediate link management are also suitable for the production of polyurethane screen panels. At the same time, increase investment in scientific research, strengthen the structural design and installation design of the screen, select excellent polyurethane raw materials, choose scientific production technology, and gradually improve the overall level of my country's polyurethane screen.
