1. Depends on the appearance of the product: First check whether the surface of the polyurethane screen is in good condition, whether the screen is flat, whether the color of the polyurethane screen is pure, whether there are broken bars, burrs, missing materials, mixed materials, and whether the joints are tight, etc.
2. From the perspective of product opening rate: Generally speaking, the opening rate is a very direct factor affecting screening efficiency: the more openings the polyurethane screen has, the higher the opening rate, and the higher the screening efficiency and output will be. .
3. From the perspective of product connection: the connection method of the polyurethane screen directly affects the screening efficiency. The polyurethane screen developed by our factory has an automatic connecting device, which is simple and time-saving, and more convenient to disassemble and assemble. It is convenient to shorten the initial installation time and the replacement time of the partial screen in use, and improve production efficiency. The polyurethane screen is tightly connected and there is no mineral leakage, ensuring the quality.
4. Check whether the sieve holes are uniform: high-quality polyurethane sieve holes are uniform and standard, and the tolerance range is small. Regardless of whether the screen holes meet the standards, illegal merchants often miss this link. They have holes in the details of their product. We should watch carefully. Generally speaking, illegal operations always present problems in more subtle jobs.
5. An excellent polyurethane screen should have moderate stiffness and flexibility: In actual production, the polyurethane screen should have strong elasticity to ensure that waist collapse does not occur during production; the polyurethane screen should have toughness to ensure Make sure the screen is not brittle. In this regard, some unscrupulous companies may not be able to manufacture and produce, because this requires higher costs and technical capabilities, and is also a more meticulous and patient work. Therefore, everyone can know what a high-quality polyurethane screen looks like when purchasing.
