Introduction to the characteristics and applications of various rubber rollers

Rubber Roller: Excellent oil resistance, good wear resistance, aging resistance, and heat resistance. They are used in printing, printing, dyeing, chemical fiber, paper, packaging, plastic processing and other equipment and other occasions where they are exposed to oil and aliphatic hydrocarbon solvents.

Natural rubber roller: excellent elasticity and mechanical strength, good alkali resistance, used in compression rubber rollers in textile, paper and leather, packaging and other equipment and traction rubber rollers in metallurgy, mining and other industries.
Polyurethane rubber roller: It has extremely high mechanical strength and abrasion resistance, aging resistance and oil resistance. It is often used in papermaking, chemical fiber, wood processing, plastic processing and other machinery.

Silicone rubber roller: using its high temperature resistance, ozone resistance, chemical inertness and non-adhesion to plastics, it is used in the processing of hot-adhesive products, such as polyethylene calendering, embossing, printing and dyeing, and coating adhesives for films and fabrics. Plastic compounding, corona treatment and other machinery are also used as release rollers on sugar production and packaging machines and non-woven fabric manufacturing.

Neoprene rubber roller: excellent abrasion resistance, high fire resistance, aging resistance, better heat resistance, oil resistance, acid and alkali resistance, used in printed board corrosion machines, plastics, tanning, printing, food printing iron, Ordinary coating machines and other equipment.

Butyl rubber roller: high resistance to chemical solvents, good heat resistance (170°C), excellent acid and alkali resistance, suitable for color printing machinery, leather making machinery, coating equipment, etc.

Ethylene-propylene rubber roller: Excellent ozone aging resistance, weather resistance, wide operating temperature, long-term work at -65°C — 140°C, excellent insulation performance, used in plastic printing machinery, tanning machinery, and general fields.

The main content of rubber roller maintenance

In the printing process, we need to make the height of the rubber roller and the text printing plate flat or slightly lower than the height of the text printing plate, so that we can get a clearer and correct printed product.
The main maintenance we need to do in the use of rubber rollers are as follows:
1. Use a professional cleaning solvent to carefully clean the rubber rollers that have been used every day. Generally, both sides need to be cleaned. After cleaning, store the rubber rollers in a special place. Wait for 24 hours before putting them into use. Maintain the use effect of the rubber roller well.
2. Remove the rubber roller from the bracket during holidays or breaks. This can prevent the rubber roller from deforming. Once the cushion roller seal is deformed, it will be difficult to handle it, which will seriously affect the use. effect.
3. Regarding the long-term storage of rubber rollers: we need newsprint or protective film to wrap them, so that the rubber rollers can be well protected from external factors. At the same time, we need to pay attention to the need to put the rubber roller in a ventilated and dark place, keep the air humidity between 0.4-0.6, and the temperature between 0-30 degrees Celsius. In addition, rubber rollers need to be far away from equipment that may produce ozone, such as rubber roller generators. Such machines will generate a certain amount of sampling, which is a fatal threat to rubber rollers.
