Four Types of Polyurethane Dewatering Screen

Date: 2021-05-11     From: Longding     Author: admin

PU polyurethane dewatering screen is an elastomer material. Polyurethane raw materials are obtained from crude oil, and their properties are similar to those of beverage bottles. Polyurethane high-frequency screen has the characteristics of beautiful appearance design, high impact toughness, heat insulation, sound insulation, noise reduction, corrosion resistance, aging resistance, and lightweight.

Four types

Polyurethane screens are generally divided into four types according to their structural forms

1. Embedded

2. Anchor bolt connection

3. Decorative strip connection

4. Screen hook connection

Comparison of polyurethane screen with general metal mesh

1. Large bearing capacity and long service life

The polyurethane screen has high elasticity and uses galvanized steel wire rope as the frame raw material. Therefore, it has high tensile strength, and its bearing capacity is 2.5 times that of stainless steel screen. The service life of polyurethane is 8-10 times longer than that of ordinary metal mesh, 3 times that of the stainless steel screen surface, and 3.9 times that of rubber. It is the raw material for the screen surface with good wear resistance at this stage. The raw material for the production of high-frequency polyurethane screens is a polymer material chemical polyurethane elastomer, which has good abrasion resistance and large bearing capacity.

2. Self-cleaning characteristics and does not block holes

Polyurethane has good leakage, and the round hole sieve has a large taper (140°), which can avoid the adhesion of wet and cold fine sand particles, so it is suitable for the classification of wet and cold fine sand raw materials.

Several aspects that need to be paid attention to when installing and applying Polyurethane dewatering screen

1. Prevent top edge leakage

2. Prevent mortar leakage and stainless steel screen damage

3. Anti-dislocation damage

4. Prevent the tension from being too loose

5. Check the support of the screen to prevent excessive support.

Matters need attention

1. Electric welding or ignition is strictly prohibited

2. Do not store under direct sunlight

3. Do not touch with thin iron wires
