Requirements for polyurethane metal cores
It will increase friction in the printing process, consume the energy of the printing machine, and reduce the life of the motor. It generates high temperatures during high-speed rolling and releases heat, which affects the ink-water balance in printing. To thin the viscosity of the ink and produce flying ink, it takes time to adjust the pressure by hand. Overheating can cause damage to the surface of the roller.
First, the impact of the expansion of the rubber roller
1. It will increase the friction in the printing process, consume the energy of the printing machine, and reduce the life of the motor.
2. It will generate high temperature during high-speed rolling and release heat, which will affect the water-ink balance in printing. To thin the viscosity of the ink and produce flying ink, it takes time to adjust the pressure by hand.
3. Overheating will cause damage to the surface of the rubber roller.
Second, the impact of rubber roller shrinkage
1. The transmission of ink is interrupted, especially when it is restarted, it takes time to adjust.
2. The distance of the ink roller is too large, and the pressure should be readjusted.
3. The ink roller becomes hard, and each printing machine manufacturer requires a certain indentation width, uniform width, and pressure becomes larger, resulting in heat to emulsify the ink and water in the bucket.
4. It must be placed for a period of time to restore its function. At present, many printing houses have this problem, and there are two reasons. First: use rubber cover rollers instead of original rollers. Second: improper maintenance of the printing machine. Therefore, the solution to the problem is to use high-quality rubber rollers and properly maintain your printing press so that it is always in good working order. We know that new machines tend to print better than old machines. In fact, it should be believed that the use of a second mobile phone can also achieve the printing effect of a new machine. The difference between the second mobile phone, in addition to the mechanical department, and the new machine Z is the balance of the water and ink path, and the quality of the rubber roller. High-quality adhesive rollers combined with careful maintenance will take your print quality to the next level.
