Notes On The Use Of Rubber Rollers!

The rubber roller is generally composed of an outer layer of rubber, a hard rubber layer, a metal core, a roll neck and a vent hole. Its processing includes roll core sand blasting, bonding treatment, glue forming, wrapping, iron wire winding, vulcanization tank vulcanization and surface processing. And other processes. Rubber roller is mainly used in papermaking, printing and dyeing, printing, food processing, metallurgy, plastic processing and other aspects. Today, Yangzhou Fengze Roller Industry Company Xiaobian takes everyone to understand the use of rubber rollers!

 1. Printing rubber rollers mainly transfer ink on offset printing machines. Therefore, the rubber roller must be cleaned carefully during daily cleaning, otherwise the surface layer of the rubber roller and pigments and resins are easily oxidized to form a smooth and hard film, which causes the surface to vitrify and affect the ink transfer. If it is not cleaned frequently, the surface of the rubber roller will be uneven to affect its use. Therefore, the rubber roller should be cleaned and put on standby during shutdown.

 2. In the offset printing operation, ink emulsification occurs due to "large water and large ink", and a hydrophilic base is formed on the smooth rubber roller to make it deink. The solution is to remove the emulsified ink, wash the deinking rubber roller with gasoline, mix and polish with 5% sodium hydroxide aqueous solution and pumice powder, and also perform corresponding treatment on the metal roller (or hard roller). Hard rollers can also be sanded with fine water sand in the state of water spraying. Be careful not to stay in the same place, otherwise the rubber roller will be damaged. The fundamental solution is to control the pH value of the water fountain fluid and improve the ink-water balance.

 3. If the rubber roller is used for too long, coupled with the erosion of chemicals, the "slag" will be caused by the rotten rubber. Do not use this rubber roller again, or it will seriously affect the print quality.

 4. In order to ensure that it does not affect the production and printing quality, there must be a spare ink roller, but do not store too much to avoid aging. The storage environment of the rubber roller is the same as that of the blanket. In addition, the rubber roller should be straight and straight at the journal, and the surface should not touch each other or other objects, so as not to deform the rubber roller.

 5. Rubber rollers should not be stored near large motors and generators. Because of the large amount of ozone generated by these devices, the surface of the rubber roller will age and crack.

 6. When the weather is cold, the ink is uneven. Add auxiliary materials to the ink. It is prohibited to use infrared heaters and other equipment to bake the ink rubber roller to prevent the rubber roller from oxidizing.
