Carrying Conveyor Idler Roller

Products Description

Polyurethane materials have excellent tear resistance and resilience, and can maintain their shape and performance even under long-term use and stress.

Excellent processing performance: Polyurethane materials have good processability and can easily be formed into various shapes and sizes of coated rollers through processes such as injection molding and casting.

At the same time, its adhesion is also quite good, allowing it to firmly bond with various substrates, thereby improving the overall performance of the coated roller.

The lifespan of rollers is affected by various factors, including material, working environment, printing quality, and maintenance. For example, factors such as temperature and humidity can directly impact the lifespan of rubber rollers; excessive printing pressure can cause irreversible damage to the rollers; and incorrect maintenance can significantly shorten their lifespan. Additionally, the lifespan of industrial rubber rollers is also related to product quality, daily usage methods, and proper installation. Therefore, proper maintenance can significantly extend the lifespan of rubber rollers and improve production efficiency and product quality.

Usage Environment

Use in a dry, clean, and temperature-appropriate environment, which will reduce the wear on the rubber roller and extend its lifespan For example, in the printing industry, if the humidity in the printing workshop is properly controlled and there is no excessive dust or impurities, the lifespan of polyurethane rollers may approach 3 years. On the contrary, if the rubber roller operates in harsh environments such as high temperature, high humidity, or strong acids and bases, its performance will be significantly affected, and its lifespan may be shortened.

Maintenance Status

Maintenance status: Regular cleaning of the rubber rollers is very important. Timely remove ink, dirt, and other residues from the surface of the rubber roller to prevent their long-term accumulation, which can lead to increased wear and tear on the roller surface. At the same time, be careful to avoid contact between the rubber roller and sharp or rough objects to prevent scratching the surface of the roller. If slight wear or signs of aging are found on the surface of the rubber roller, timely polishing or repair can be performed, which can also extend its service life to some extent.

Advantages

Good chemical properties: Polyurethane rollers have special resistance to solvent components in various inks, dampening solutions, and cleaning agents, making them suitable for UV ink rollers and varnish rollers, etc. It has good solvent resistance to boiling water, diesel, gasoline, lubricating oil, kerosene, toluene, alcohol, and salt solutions, but is not resistant to acetone, ethyl acetate, and strong acids and bases.

Excellent physical properties: Polyurethane rollers do not harden or age with long-term use, and they have good tear resistance and rebound properties, as well as excellent wear resistance. Therefore, they have a long service life, are easy to store, and long-term storage does not affect their performance. Experiments show that the tensile strength and wear resistance of polyurethane rollers are 3 and 5 times that of natural rubber rollers; they have better compression set and resilience; and the service life of polyurethane rollers is more than 3 times that of ordinary rollers.

Strong adaptability: Polyurethane rollers have a wide range of hardness indicators, from HSA15 to HSD80, which can meet the hardness requirements of different types of printing machines In addition, it can adapt to the high temperature and humidity environments of southern printing workshops and the cold, dry climate conditions of the north, and its dimensions will not change significantly under different temperature and humidity conditions.

Good elasticity and resilience: Polyurethane rollers have excellent elasticity and resilience, which allows them to quickly return to their original shape after being subjected to pressure, ensuring a tight fit with the contact object. In the printing industry, polyurethane rollers with good elasticity can better adapt to different paper thicknesses, ensuring that ink is evenly transferred onto the paper. The rebound rate of high-quality polyurethane rollers can reach 30%-50%.
