Surface coating technology

Polyurethane rubber roller has the advantages of wear resistance, corrosion resistance, good elasticity, etc. It is suitable for the matching roller of new materials such as polishing, oil, metallurgy and iron printing of imported equipment. Polyurethane rollers are suitable for all kinds of machinery and have many superior characteristics.

1, the product hardness index is wide, hardness from HSA15 to HSD95, can meet the requirements of different types of mechanical roller hardness.

2, the colloidal surface of the product is fine and smooth, the appearance of the color is bright, the colloidal material and the core shaft are firmly bonded. The size of the roller is strictly controlled, and the size does not change greatly with temperature and humidity. It can adapt to the high temperature and high humidity environment of the southern workshop and the cold and dry climate conditions of the north.

3, the product has good chemical properties, suitable for various types of ink and printing methods. It has special resistance to solvent components in various ink, moistening solution and cleaning agent. Polyurethane rollers are also suitable for UV ink rollers and glazing rollers, especially for boiling water, diesel, gasoline, lubricating oil, kerosene, toluene, alcohol and brine solutions have good solvent resistance. But not resistant to acetone, ethyl acetate and strong acids and bases.

4, polyurethane rubber roller colloids have enough surface viscosity, can ensure that the rubber roller in the printing process has good ink transfer and inking performance, its good ink performance can ensure high quality printing.

5. Polyurethane rubber roller has excellent physical properties, long-term use of rubber roller will not harden, aging, and tear resistance, good resilience, excellent wear resistance, so long service life, easy to save, long-term storage does not affect the use of effect; Can withstand high pressure, high speed, high temperature, high humidity production environment. The experimental results show that the tensile strength and wear resistance of polyurethane roller are 3 times and 5 times that of natural rubber roller. Compressive permanent deformation, good resilience; The service life of polyurethane rubber roller is more than 1 times that of ordinary rubber roller.
6. Polyurethane roller is easy to clean, easy to convert dark and light ink, easy to print color change.
7. Polyurethane roller has excellent hydrophilicity, so it can be used as a rubber roller of water and alcohol moistening system, and the effect is very good.

Precautions for use

1. Use should avoid contact with ethyl acetate, butyl acetate, acetone, butyl ketone and other solvents and strong acids, strong bases.

2. When installing the roller, the core should be in a parallel position, and the pressure between the roller and the surface of the roller must be uniform.

3. When storing the roller, a special roller frame must be used to ensure that the surface of the roller is not under pressure and does not contact any other objects for a long time.

4. After daily shutdown, the paper wool and ink residue on the surface of the roller must be cleaned with cleaning liquid.
