Industrial Application of Polyurethane Roller

Industrial application of polyurethane roller

There are many kinds of polyurethane rollers, including hard, soft and polyurethane elastomers, which can also be divided into thermoplastic and thermosetting. It is now a good heat insulation material in the world, because it has good oil resistance, toughness, wear resistance, aging resistance and adhesion, so it is also widely used. Polyurethane materials will appear in the construction industry, transportation industry, chemical industry, including household. In terms of furniture, for example, it can play a role in sofas, mattresses and chair armrests. When polyurethane coated rubber is used in mechanical parts, the advantages of polyurethane rollers are also many. First, the hardness increases, and then the strength also increases. Compared with rubber, their breaking strength, tear strength and load-bearing capacity are much higher than ordinary rubber.

Polyurethane rollers have the characteristics of high strength, compression resistance, wear resistance, oil resistance, acid and alkali resistance, corrosion resistance, tear resistance, impact resistance, wide range of hardness, strong bonding with metals, and no degumming. Widely used in metallurgy, papermaking, electronics, chemical fibers, wood processing, textiles, printing, printing and dyeing ceramics, mining, power transmission and other industries. Newly manufactured rubber rollers Newly cast rubber rollers shall not be put into use immediately. Because the internal structure of the newly cast rubber roller is not stable enough, it is easy to reduce the service life when it is put into use immediately. It is recommended to place the new rubber roller for a period of time to keep the rubber roller in a relatively stable state after contact with the temperature and humidity of the external environment, which can increase the toughness of the colloid, thereby improving the durability effect. The colloid used for polyurethane rollers has sufficient surface viscosity, which can ensure that the rubber rollers have good ink transfer and inking performance during printing, and its good ink affinity can ensure high-quality printing. The appearance is bright, the surface of the colloid is fine and smooth, and the colloid material and the mandrel are firmly bonded. The size of the rubber roller is strictly controlled, and the size will not change greatly under different temperature and humidity conditions. It can adapt to the high temperature and high humidity environment of the printing workshop in the south and the cold and dry climate in the north. Polyurethane rollers have good chemical properties and are suitable for various types of inks and printing methods. It has exceptional resistance to solvent components in various inks, fountain solutions and cleaning agents. Polyurethane cots are also suitable for UV ink cots and glazing cots, especially for boiling water, diesel, gasoline, lubricating oil, kerosene, toluene, alcohol and saline solutions. However, it is not resistant to ethyl acetate and strong acids and alkalis.

Usually, the internal structure of the newly manufactured polyurethane roller is not stable enough. If it is put into use immediately, its service life will be shortened. Therefore, the polyurethane roller should be placed outside for a period of time to maintain relative stability, which can increase the toughness of the colloid, thereby improving the durability effect. Polyurethane rollers have the advantages of high strength, high tear strength, etc., and can withstand high-pressure and high-humidity production environments.
