The rubber roller is a roll-shaped product made of metal or other materials as the core and covered with rubber through vulcanization.
The rubber roller is a roll-shaped product made of metal or other materials as the core and covered with rubber through vulcanization.
Chinese name: rubber roller
Foreign name: rubber-covered roll
Material: Use metal or other materials as the core, covered with rubber
Definition: Rolled products made by vulcanization
Classification: Papermaking rubber rollers, printing and dyeing rubber rollers, printing rubber rollers, etc.
The main types of precautions, common faults, maintenance, debugging and maintenance, applicable industry applications, market applications, pre-processing
Classification
According to the purpose, it can be divided into: papermaking rubber rollers, printing and dyeing rubber rollers, printing rubber rollers, grain hulling rubber rollers, metallurgical rubber rollers and mimeograph rubber rollers, etc.;
According to the surface shape, it can be divided into: flat roller and pattern rubber roller; according to the material, it can be divided into: butyl rubber roller, nitrile rubber roller, polyurethane rubber roller and silicone rubber rubber roller.
Rubber rollers are generally composed of outer rubber, hard rubber layer, metal core, roller neck and vent holes. Its processing includes roller core sandblasting, bonding treatment, glue forming, cloth wrapping, iron wire winding, vulcanization tank vulcanization and surface processing And other processes. Rubber rollers are mainly used in papermaking, printing and dyeing, printing, food processing, metallurgy, plastic processing, etc.

Precautions
* The printing rubber roller mainly transfers ink on the offset press. Therefore, the rubber roller must be cleaned carefully during daily cleaning, otherwise the surface layer of the rubber roller and the pigment and resin are easy to oxidize to form a smooth and hard film, which will cause the surface to vitrify and affect the ink transfer. If it is often cleaned and not clean, the surface of the rubber roller will be uneven over time and affect its use. Therefore, the rubber rollers should be cleaned and stored for later use when the machine is stopped.
* In the offset printing operation, the ink is emulsified due to "large water and large ink", forming a hydrophilic foundation on the smooth rubber roller, making it deinking. The solution is to shovel the emulsified ink, wash the deinking rubber roller with gasoline, mix and polish with 5% sodium hydroxide aqueous solution and pumice powder, and also deal with the metal roller (or hard roller) accordingly. The hard roller can also be polished with fine water sand under the water sprinkling state. Be careful not to stay in the same place, otherwise it will damage the rubber roller. The fundamental method is to control the pH value of the hopper liquid to improve the ink and wash balance.
* The rubber roller has been used for a long time and is aging, coupled with the erosion of chemicals, causing the rotten glue to lose "slag". It is best not to use such a rubber roller, otherwise it will seriously affect the quality of printing.
* In order to ensure that the production and printing quality will not be affected, spare ink rollers must be provided, but do not store too much to avoid aging. The storage environment of the rubber roller is the same as the blanket. In addition, the rubber roller should be set up straight at the journal, and the surface should not be in contact with each other or with other objects to avoid deformation of the rubber roller.
* Rubber rollers should not be stored near large motors and generators. Because the large amount of ozone produced by these equipment will cause the surface of the rubber roller to age and crack.
* When the weather is cold, the ink may not be evenly printed, and auxiliary materials can be added to the ink appropriately. It is forbidden to use infrared heaters and other equipment to bake the ink roller to prevent oxidation of the rubber roller.
