Cots definition:
Made of metal or other material as the core, rubber covered roller shaped products which is made by curing.
Classification
By end use can be divided into paper rolls, printing and dyeing, printing rubber roller, rubber roller rice huller rollers, metallurgical rollers and mimeograph rollers;
According to surface morphology can be divided into flat roll and the pattern of rollers;
According to the material and can be divided into butyl rubber, nitrile rubber, polyurethane rubber roller and rubber roller.
Generally consists of an outer layer of glue, hard rubber, metal core, roll neck and a breather.
The process comprises a roller core sand adhesive glue, processing, molding, cloth, wire winding, autoclave curing and surface processing process.
Rubber roller is mainly used in papermaking, printing and dyeing, printing, food processing, metallurgy, plastics processing etc..
Roller type commonly used and use
* natural rubber:
Excellent flexibility and mechanical strength, good alkali resistance, used in the textile, paper and leather, packaging equipment to compact type roller and metallurgy, mining and other industries pulling rollers.
* nitrile rubber:
Excellent oil resistance, abrasion resistance, aging resistance, heat resistance and good performance, used in printing, printing and dyeing, chemical fiber, paper, packaging, plastic processing equipment and other contact with oil and fat hydrocarbon solvent.
* chloroprene rubber:
Excellent abrasion resistance, high fire resistance, aging resistance, good heat resistance, oil resistance, acid and alkali resistance, used for PCB etching machine, plastic, leather, printing, food, printing, the common coating equipment.
* butyl rubber roller:
High resistance to chemical solvents, good heat resistance (170 ℃), good acid and alkali resistance, suitable for color printing machinery, leather machinery, coating equipment.
* ethylene propylene rubber roller:
Excellent resistance to ozone aging, weather resistance, wide using temperature, can work under -65 ℃ - 140 ℃, excellent insulation properties, used for plastic printing machinery, leather machinery, general domain.
* rollers:
With particularly high mechanical strength and wear resistance, aging resistance and oil resistance is also very good, commonly used in papermaking, chemical fiber, wood processing, plastic processing machinery.
* silicone rubber cots:
The high temperature resistance, ozone resistance, chemical inert and non adhesion to the plastic, used for processing hot sticky products, such as polyethylene calendering, embossing, printing and dyeing, film and fabric coated with adhesive, plastic composite, corona processing machinery, is also useful for the sugar production and packaging machine for release roll and non-woven fabrics manufacture.
* fluorine rubber roller:
With particularly high heat resistance, oil resistance, acid and alkali resistance properties, permeability, electrical insulation, aging resistance, flame resistant, wear-resisting performance is also very good, for the special coating equipment.
* carbon fiber roller:
Light weight, high strength, high temperature resistant. For wide film industry and other special.

Debugging and maintenance of printing rollers
The importance of long-term engaged in the printing industry personnel are very clear printing rollers. Because of its direct relation with the printing plate, and the quality of the products has have all kinds of connections with contact, whether you use offset printing machine, letterpress printing, gravure printing machine, flexo printing machine are faced with how to choose and debugging skills. If according to the operation law it can not be reasonably utilized and, not only printed not ideal and perfect product, but also damage the rollers, but also shorten the useful life of the plate. The printing roller to adjust to the best extent and ideal point has the certain difficulty, is not a short duration of time to master the. Because it has no fixed program, all by the machine in the long-term production practice summary, exploration, mining, innovation, sort out a set of effective printing skills. So a good debugging printing rollers is essential.
