Lower sleeved roller manufacturers tell you that there are two types of printing rubber rollers, which are divided into hard rollers and soft rollers, which are used in printing machinery as rubber rollers for embossing, ink adjustment, and ink transfer.

Polyurethane offset printing rubber roller body has sufficient surface viscosity. Therefore, the rubber roller has good ink transfer and ink holding performance during the printing process, and good ink performance can ensure a certain quality of printing.
The rubber roller has moderate hardness and elasticity, high oil resistance, washing solvent resistance, abrasion resistance and shape stability. Soft rolls are generally made of SBR, CR and PU. The surface of the hard rod was originally made of copper and later replaced with polyester resin.
The Lower sleeved roller manufacturer tells you that printing rubber rollers usually have wear, holes and other phenomena during the work process. If you replace the new rollers, the cost will be too high and the production schedule will be affected. Rubber patch can be used or repaired.
When the printing rubber roller is stored, it should be stored with the shaft supported, and it is strictly forbidden to squeeze and stack, and the distance between the rollers should not be less than 5mm.
In the offset printing process, the key is the control of the balance of the water path and the ink path, and the balance of the ink and ink depends on the key components of the rubber roller and the ink roller, and their quality can directly affect the product quality. This is especially true for gravure, embossing, and flexo printing. Lower sleeved roller manufacturers tell you that general printing companies need to maintain equipment once a week, including the maintenance of printing rubber rollers, as follows:
1. After the daily production operation is completed, the rubber roller should be carefully cleaned and washed twice.
2. To clean the printing rubber roller, use specified chemical preparations, such as industrial alcohol, etc., and do not use corrosive solvents.
3. The manufacturer of the Lower sleeved roller tells you that the surface protection of the printing rubber roller can be wrapped with newsprint and placed in a ventilated and dark place.
