What is the chemical function of the rubber roller?

Rubber cots are used to process hot stick products due to their high temperature resistance, ozone resistance, chemical laziness and non-stick plastics. What is its chemical function? The following is the small make up:

1. Corrosion resistance: mainly for printing, various chemicals that are often contacted, such as some corrosive substances contained in ink, paper, fountain solution, cleaning agent, etc. Therefore, the rubber rubber roller should have a certain anti-corrosion ability.

2. Conductive: In the process of sheet-fed printing, paper, ink and other materials simply generate static electricity under unsuitable conditions, which may cause the ink to wrap the roller and transport two sheets of paper. Therefore, in order to ensure the normal transportation of paper and ink, it is necessary for the rubber roller to have an antistatic function. However, the electrostatic pressing roller of a gravure printing press needs to carry a certain amount of charge under certain conditions.

3. Thermal conductivity: any material has an upper limit of high temperature resistance. The high temperature resistance of the material directly determines the life of the rubber roller. Especially high-speed newspaper rotary printing presses and commercial rotary printing presses, the speed of these machines has reached 60,000 rpm, and high-speed work will inevitably generate high heat, so it is required that the rubber roller of the printing press needs to have good heat transfer to ensure its normal operation. Service life and print quality.

4. Correctness of water handling: The water roller should have hydrophilicity and ink repellency. A good water roller should be able to spread water or fountain solution evenly on the surface of the rubber roller, and maintain a certain amount of moisture on the surface. At the same time, the water roller used to transmit the alcohol fountain solution needs to be transmitted quickly, and the correctness of its transmission is very important to maintain the balance of ink and water.

5. Ability to cooperate with chemical solvents: The coordination between the surface material of the rubber roller and the chemical composition of the cleaner, ink and fountain solution will prevent the development of their respective functions.

The use of rubber cots provides a lot of assistance for production and processing, and it is used in drawing frames, rovings and spinning frames in the cotton spinning industry. Hope the above will help you.
