The usual maintenance of polyurethane screens is mainly divided into three periods, before starting, during starting, and after use. Maintenance and inspection work in each period is very necessary. We will briefly introduce the specific content in two parts

1. Before starting: Check whether the screen is damaged. Whether each set of clamps can be locked;

2. During starting: Pay attention to whether there is abnormal noise. Whether the current is stable. Whether the vibration is abnormal;

3. After use: Clean it up after each use.

Regular maintenance of polyurethane screens:

1. Check the coarse and fine meshes and springs regularly for fatigue and damage, and whether the various parts of the machine body are damaged due to vibration.

2. After the motor runs for about two weeks, it is necessary to add the appropriate lithium-based grease (ZL-3). After a cumulative operation of 1500 hours, check the bearings and clean them immediately if they are damaged.

As a hard polyurethane, polyurethane rack pads have excellent properties such as light weight, low thermal conductivity, good heat resistance, aging resistance, easy bonding with other substrates, and no droplets when burned. They are widely used in polyurethane screen accessories.

Polyurethane rack pads are a high-performance polymer material. They have become the fifth largest plastic after polyethylene, polyvinyl chloride, polypropylene, and polystyrene. The global total output has exceeded 10 million tons/year. In recent years, my country's polyurethane industry has made great progress. As polyurethane screen accessories, they have been widely used and have huge development space.
