Plate cleaning roller for gravure printing and its manufacture

Abstract

A plate wiping roller for the carved-plate gravure printing of paper money is made up through preparing slurry from PVC resin, plasticizer, filler, stabilizer, lubricant, monomer, teflon and modifier ABS, preparing raw roller, preheating the roller, coating said slurry on said roller and plasticizing. Its advantages are low cost and high quality.

Description

technical field

[0001] The invention relates to an engraved gravure wiping roller, in particular to a raw material formula and a manufacturing process of the engraving gravure wiping roller. Background technique

[0002] For a long time, gravure wiping rollers have been processed and produced by various enterprises. Due to the low printing durability, the frequency of use and replacement is high, resulting in a huge consumption of raw materials for making wiping rollers. The process technology basically follows the process standard and formula provided by the foreign party when the super wiring notch is used. The raw materials used are all imported raw materials, which are expensive, the purchase channel is quite complicated, and sometimes the quality is not stable enough. In addition, in order to meet the sizing requirements in the production of gravure wiping rollers, the prepared slurry is required to have a low viscosity value at a high shear rate. After coating, the co...
