A wide variety of rubber, each with characteristics of manufacturing rubber roller to fitness an essential material.
??? Most use rubber rollers are good use of the flexibility, for the hardness and thickness of the choice must be carefully decided, rubber hardness and thickness of the choice can not be arbitrary, arbitrary selected, but a certain limit.
???? 1. Hardness in the following 40 °, it is difficult to make high-strength rubber, therefore, pressure rolls of plastic, must not use low hardness of the formula, soft rubber rolling deformation very large, the internal heat-aging health and shorten life .
???? 2. Vulcanized rubber thickness and heating are closely related and must be some restriction, because rubber itself is a poor conductor of heat, thickness is bound to increase inequality in curing the phenomenon.
???? 3. Thickness of rubber on the principles of unilateralism to 10 mm more than the standard, rubber roller thickness below 10 mm, due at the core of impact, hardness will be more practical for high, soft rubber in particular the impact on the larger. In addition, the smooth surface of the principle of acupuncture should be encumbered with the determination of the vertical surface. Face and beat lightly with the face subsidy pressure of contact, and read out by the scale degree.
???? 4. Test the temperature to 20 ℃ as the standard, low temperature, hardness generally higher, the lower the temperature, hardness, hardness standards as the temperature effects of change.
???? 5. Affected by the above factors, as well as those of the individual error, the outcome of that concept figures. So hardness is usually allowed for the error ± 5. In addition to the hardness of a correction regularly every three months.
