Here are some ways to maintain and maintain rubber rolls to extend their service life:
Daily cleaning: After each use, the rubber residue, dust and other impurities on the surface of the roll should be removed in time. You can use a clean wet cloth or special cleaning tools to wipe, avoid using sharp or hard tools, so as not to scratch the surface of the roll. For some stubborn stains, you can use a mild cleaning agent to clean, but pay attention to avoid contact with the bearing and sealing parts of the rubber roller, to prevent corrosion or damage.
Regular inspection: Check the surface condition of the roll regularly to see if there are wear, scratches, cracks, deformation or degumming problems. If slight damage is found on the surface, it can be repaired in time to avoid further deterioration of the problem. At the same time, check the bearings and seals of the roll to ensure that they work normally, if there is wear or leakage, should be replaced in time.
Control working environment: the rubber roll should work in the appropriate temperature and humidity environment, the general temperature control at 20℃ -40 ℃, the relative humidity at 40%-60% is appropriate. Avoid the roller exposure to high temperature, high humidity, strong acid, strong alkali and other harsh environment, so as not to affect the performance of rubber and roll life. In addition, to keep the workplace clean, reduce dust and impurities on the roll pollution.
Correct operation and use: the operator should operate in strict accordance with the operating procedures, avoid overload and overspeed operation, and prevent the roll from sudden impact or excessive pressure. When starting and stopping the equipment, it is necessary to operate smoothly to avoid violent vibration of the roll. At the same time, according to the characteristics of rubber materials and processing requirements, reasonable adjustment of roll clearance, pressure and temperature parameters to reduce roll wear.
Regular lubrication: the bearings and transmission parts of the roll are regularly lubricated to reduce the coefficient of friction and reduce wear. Select the appropriate lubricant and add it according to the specified lubrication cycle and lubrication amount. During the lubrication process, care should be taken to avoid contaminating the roll surface with lubricant.
Proper storage: If the roll needs to be idle for a long time, it should be stored in a dry and well-ventilated place, and appropriate protective measures should be taken, such as the use of protective covers or packaging materials to wrap the roll to prevent dust, moisture and other harmful substances. At the same time, to avoid heavy pressure or deformation of the roll, it is best to place it horizontally or hang it.
Professional maintenance: Regular comprehensive inspection and maintenance of the roll by professionals, including the accuracy of the roll detection and calibration, repair or replacement of serious wear parts. For some large or complex rubber rolls, non-destructive testing technology can also be used, such as ultrasonic detection, magnetic powder detection, etc., to detect whether there are defects inside the roll.
