Hebei Chunfeng printing rollers

* Offset printing rollers on the main transfer ink. Therefore, the daily cleaning rubber roller must be carefully cleaned, otherwise it would be the roller surface layer and pigments, resins oxidation layer of smooth, hard film, resulting in the glass surface and affect ink transfer. If you frequently wash without a net, falling rubber roller surface will be uneven and bad use. So, stop should be put away cot wash stand. * In offset printing operations due to "big water Melbourne" produce ink emulsion, on a smooth rubber roll forming hydrophilic base, it deinking. The solution is to shovel out the emulsion ink, the inking rubber roller wash with gasoline, hybrid grinding with 5% aqueous sodium hydroxide and pumice, while the metal roll (or hard roll) has to be done accordingly. Hard roll can also be sprinkled in the water washout status, sanded with fine water, careful not to stay fixed in the same ocean area, otherwise it will damage the rollers. The fundamental solution is to control the fountain solution pH value, improve water balance. * Cots and used for a long aging, coupled with the erosion of chemicals, resulting in bad glue off "slag", such Cots best not to use, or seriously affect the printing quality. * To ensure that does not affect the production and printing quality, you must have a spare ink roller, but do not store too many to avoid aging. Storage environment Cots and blankets same. In addition, the rubber roller journal at the flat rack should be good, and the surface do not touch each other or in contact with other items, so the rubber roller deformation. * Cots and should not be stored in the vicinity of large motors, generators place. Because a lot of the roller surface ozone causes aging of these devices produce split. * When the weather is cold, the ink hit uneven, may be appropriate to add supplementary material in the ink, prohibit the use of infrared heating device such as baking ink roller, rubber roller to prevent oxidation. Edit this paragraph Cots proper use and maintenance of a number of essentials * new casting Cots not immediately put into use. Because the new casting rolls of plastic internal structure is not stable enough, if immediate use, easy to reduce the service life. It is just out of the barrel of new rubber roller should be placed for some time, so that the rubber roller after contact with ambient temperature and humidity, to maintain a relatively stable state, which can increase the resilience of the colloid, thereby enhancing the durability of the effect. * Idle rubber roller properly stored. Cots inactive should be cleaned after the colloid packets with plastic film up on the rubber roller rack, it must not be stacked in one or a few casually leaned dig vertical walls, so as not to suffer undue loss colloid . Cots waste during transport taken casting process, should not mess abandonment pressure or stress, to keep the roll core is not eccentric, bend, in order to ensure the normal use of the roll core. * Rubber roller head bearings should be kept well lubricated. We know that precision rubber roller head, bearing direct how a direct impact on ink transfer, cloth ink effect. If poor lubrication caused rubber roller head, bearing wear, the gap will inevitably lead to uneven printing ink ills. But also because the jump glue, plastic and other inconveniences caused by slip printed bar marks. So, usually it should be ground to a rubber roller head, bearing filling oil to prevent engine wear rubber roller normal use, to ensure print quality.
