Polyurethane coated roller is suitable for all kinds of transmission machinery and consists of wheel core and polyurethane coated layer. Performance characteristics of polyurethane coated rollers:
1. The appearance is bright in color, the colloid surface 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 high temperature and high humidity environment and severe cold and dry climatic conditions.
2. Polyurethane coated rollers have good chemical properties and are suitable for all types of conveyors.
3. Polyurethane coated rollers have a wide range of hardness indicators, from HS15 to HS90, which can meet the hardness requirements of different types of rubber rollers.
4. Polyurethane covered roller has sufficient surface viscosity.
5. Polyurethane coated roller has excellent hydrophilicity, so it can be used as a water and alcohol dampening system rubber roller with good effect.
Matters needing attention when using polyurethane coated roller:
1. Avoid contact with solvents such as ethyl acetate, butyl acetate, acetone, butanone, and strong acids and alkalis during use.
2. When installing the rubber roller, check it to the parallel position, and the force of the rubber roller must be even.
3. When storing the rubber roller, a special rubber roller rack must be used to ensure that the surface of the rubber roller is not pressed and does not touch any other objects for a long time.
The influence of the workshop environment on the product. When the high temperature and humid weather and dusty environment are generated from the surroundings, the high-speed operation of the machine will cause the surface temperature of the rubber roller to continue to rise, and the heat will expand, increase friction, and shorten the service life. Therefore, in a factory with conditions, the offset printing plug-in needs to be installed with air conditioning to maintain the workshop temperature, so that the machine can run in a good environment, and only in a good workshop environment can high-quality products be produced.
