How to choose the material of the rubber roller, today we will share some points
1. Chemical resistance---In order to meet the oil resistance, solvent resistance and chemical resistance, it is more suitable for synthetic rubber, such as printing rollers must be solvent resistant, oil resistance, acid resistance, etc.
2. Physical properties---rubber elasticity, flexion, impact, wear...etc sex.
3. Economy---The price of rubber rollers varies greatly due to the choice of different materials, so the value and life should be measured and compared from time to time. For example, ordinary heat-resistant 150-degree rollers must use high-priced rubber.
4. Heat resistance - high temperature use will easily make the rubber ageing. In addition to the core design, the cooling system must be considered, and the rubber material must be carefully selected, such as for the plastic industry and paper industry, not only wear resistance but also Consider heat resistance and heat dissipation.
The bearing and shaft head structure inside the rubber roller is very precise, and a slight difference will directly affect the use effect. If the lubrication of the bearing and the shaft head is not very good, it is easy to cause wear and tear, and it will seriously affect the quality of the rubber roller, thereby affecting the quality of the product.
How to properly store unused rubber rollers
The correct storage method is: wash the rubber roller with clean water, then seal it with plastic film, it is best not to let it come into contact with the air, and then put it in a special storage place, and must not be thrown around, affecting its internal machinery. performance and quality of the rubber surface.
The inner bearing and shaft head need good lubrication. We suggest that under daily circumstances, it is best to perform certain maintenance on the rubber rollers used every week, and to lubricate the rubber surface and interior well enough.
