The first step of mixing is to control the content of each ingredient and the temperature of the baking, so that the hardness and ingredients can be relatively stable. After mixing, because the colloid still has impurities and is not uniform, it must be filtered. In addition to ensuring that the colloid is free of impurities, the filter must also ensure that the rubber roller can be uniformly stressed during operation. The step of making rubber rollers and filtering is particularly important for high-speed printing machines, so as to prevent expansion or contraction caused by different reasons.
Then the industrial rubber roller is heated, pressurized and vulcanized to stabilize the plasticizer, so that once the rubber shrinks during use, the shrinkage can be reduced to a minimum. The curing process can make it soft and firm without losing its softness, and finally can better transfer the ink.
The last is grinding and polishing. Do not need a constant constant temperature for these two steps. Otherwise, the temperature is too low, it is easy to be brittle locally, and the temperature is too high. The surface of the industrial rubber roller is prone to carbonization, and the phenomenon of peeling occurs during printing, which will cause the quality of the rubber roller to decline, without its good characteristics, and cannot transfer ink well. , Resulting in waste. These last two steps are the key to determining the quality of the rubber roller. Although the surface of the industrial rubber roller looks relatively smooth, there are still many small irregularities on the surface. Grinding and polishing are to make the rubber roller more precise in size, smoother surface, better ink transfer performance, and higher printing quality
