Polyurethane rollers are rollers made of polyurethane material and are mainly used in transportation equipment such as conveyors and elevators. Polyurethane rollers have excellent wear resistance, oil resistance, aging resistance and high elasticity. They can work normally in harsh environments such as high temperature, low temperature, humidity, acid and alkali, and are widely used in coal, steel, chemical industry, mines and other industries. in the conveyor system.

The manufacturing process of polyurethane rollers usually uses casting or calendering to combine polyurethane materials with metal or other materials to form rollers with specific properties and shapes. Because polyurethane rollers have the characteristics of high elasticity, high load-bearing capacity and long life, they can significantly reduce the maintenance and operating costs of conveyors and improve conveying efficiency.

Polyurethane rollers have many advantages:

High wear resistance: Polyurethane has very good wear resistance, which means it lasts longer.

Self-lubricating performance: The good self-lubricating performance of polyurethane rollers means that the belt will not be damaged during use.

Excellent mechanical properties: Polyurethane elastomer has high tensile strength, tear strength and wear resistance, as well as good compression recovery and fatigue resistance.

Good chemical resistance: Polyurethane elastomers can withstand a variety of chemicals, including oils, aliphatic and aromatic solvents, as well as acids, alkalis, salts and other inorganic substances.

Excellent shock absorption performance: Polyurethane elastomer has a large internal resistance, can absorb a large amount of vibration energy, and has good shock absorption performance. Therefore, it is widely used in situations where shock absorption is required, such as vehicles, buildings, and precision instruments.

Good processing performance: Polyurethane elastomer can be molded using plastic processing methods, such as injection molding, extrusion and blow molding. Its processing temperature is low, its speed is fast, and its adjustable range is wide.

When using polyurethane rollers, you need to pay attention to the following matters:

Avoid contact with some solvents such as ethyl acetate, butyl acetate, acetone, methyl ethyl ketone, strong acids, and strong bases, as this may affect its performance.

When installing the rubber roller, make sure it is in a parallel position to ensure uniform pressure between the rubber rollers and between the rubber roller surface and the layout.

When storing rubber rollers, a special rubber roller rack must be used to ensure that the surface of the rubber roller is not pressed and avoid long-term contact with other objects.

After daily shutdown, cleaning fluid must be used to clean the paper wool and ink residue on the surface of the rubber roller to maintain its performance and extend its service life.
