Customized polyurethane roller PU Rubber Rollers manufacturers
Polyurethane cots are mainly used to transfer ink on an offset press. Therefore, daily cleaning cots must be carefully cleaned, otherwise it will make the surface layer of cots and pigments, resin oxidation to generate a layer of smooth and hard film, resulting in surface vitrification and affect the transfer of ink. If the frequent cleaning is not clean, the surface of the cots will be uneven and not good to use. Therefore, when the machine is shut down, the rubber roller should be cleaned and put in reserve.
In the operation of polyurethane cots, the ink is emulsified because of the "large water and large ink", and the hydrophilic foundation is formed on the smooth cots, so that it is deinked. The solution is to remove the emulsified ink, clean the deinking rubber roller, mix and polish with 5% pumice powder, and make corresponding treatment for the metal roller. Hard roller can also be polished with fine water sand in the state of water sprinkling, pay attention to not be fixed in the same part, otherwise it will damage the polyurethane rubber roller. The basic method is to control the pH value of the water bucket and do a good job in ink balance.
Polyurethane cots used too long aging, coupled with the erosion of chemicals, resulting in rotten glue off "residue", such cots do not use, otherwise seriously affect the quality of printing.

What rubber rollers wheels can we make?
1. NBR rubber roller:NBR rubber roller can be used as printing roller, food industry rubber roller, dyeing roller in textile printing in dustry and the soft rubber roller for contacting solvent and so on.
Note: The NBR has poor ozone resistance and the operation should be avoided in a high concentration ozone environment during processing.
2. Neoprene roller:Suitable for the soft printing roller, gravure printing roller and so on.
3. Silicone roller:High temperature resistance which can reach 200-250 degrees, and good chemical resistance,but it has low tensile strength.Silicone roller can be used in fabric heat setting, plastic heat setting embossing, calendering, photocopying and so on.
4.Polyurethane rubber:It has outstanding tensile strength wear resistance and crack resistance and good resistance to a variety of solvents.
5. Mirror roller:We generally adopt 45 # steel, alloy steel seamless pipe, precision forgings as the material.The surface of the roller finish degree can reach RA0.01. Mirror processing can ensure the roller surface flatness, balance, non-roundness, coaxial degree meet the customers'requirements.

What is rubber roller ?
Structure of bearing and shaft head inside the rubber roller is very precise, and a slight difference will directly affect the use effect. If lubrication of bearing and shaft head is not very good, it's easy to cause wear and seriously affect the quality of rubber roller, which will affect product quality.
Rubber rollers are widely used in textile, printing and dyeing machinery (rolling roller, printing machine rubber roller, coating rubber roller, setting machine rubber roller etc.), paper making,Plastic printing, packaging, industrial, wood, glass, steel metallurgy, tobacco, transportation and other equipment

Features and applications of PU Rubber Roller
Here are some basic introductions to PU Rubber rollers wheels:
1. Strong wear resistance: Polyurethane rubber has excellent wear resistance, allowing the rubber roller to resist friction and wear and maintain stable performance during long-term use.
2. Chemical stability: Polyurethane materials have good corrosion resistance to a variety of chemicals and solvents, allowing rubber rollers to operate stably for a long time in chemical and other environments.
3. Good elasticity and bending: Polyurethane rubber has good elasticity, which helps slow down shock and vibration, while its bending allows the roller to adapt to a variety of working conditions.
4. Low water absorption: The low water absorption of polyurethane rubber means that the rubber roller can maintain good performance in a humid environment and is not susceptible to moisture.
5. Good oil resistance: Polyurethane rubber has strong resistance to oil, making it excellent in application scenarios involving grease or lubricating oil.
6. Low noise level: The polyurethane rubber roller has a flat surface and low friction, so the noise generated during operation is relatively low, which helps to improve the comfort of the working environment.
7. Lightweight and high strength: Polyurethane material is relatively light but has high strength, which allows the rubber roller not only to reduce the equipment load, but also to withstand greater working pressure.
8. Easy to process and customize: Polyurethane materials are easy to process and shape, and rubber rollers can be customized according to specific needs to adapt to different equipment and process requirements.
Generally speaking, polyurethane rubber rollers have become an important component widely used in printing, packaging, chemical industry and other fields through their multiple characteristics such as wear resistance, chemical corrosion resistance, and elasticity.
