1- What is a rubber roller?
Rubber rollers are referred to as rollers that are covered with rubber on their outer layer, which is a hard rubber-grade. In addition, these rollers have a metal core, roll neck and a vent hole.
2- Processing of roller roller
The first stage of the rubber roller processing is the roller core blasting, then it is applied to bonding and then the adhesive molding. The next step is to make wrapping and welded wire, and finally the vulcanization tank is vulcanized and at the end the roller rubber surface is processed.
3- Applications of roller roller
Rubber rollers are used in many applications today and are being added to their application range every day. Generally, these rubber rollers can be used in paper making, printing and dyeing, printing, processing, grain processing, metallurgy, plastic processing, etc.
4- Classification and Types of Roller Bearing Features
- Silicone rubber roller
One of the most common types of rubber rollers that are manufactured using synthetic rubber silicon. These rollers are very popular because of their high resistance to high temperatures of between 200 and 250 degrees C and extremely good chemical resistance.
However, these rollers do not have much tensile strength and tearing strength. For this reason, silicon rubber rollers are commonly used for purposes such as fabric heat setting, plastic heat setting embossing, photocopying, and so on.
- Polyurethane rubber roller
Another type of synthetic rubber for the production of roller rubber is synthetic polyurethane rubber. This type of rubber is highly effective against wear and cracking due to its high tensile strength and, at the same time, good resistance to abrasion and cracking. Polyurethane rubber is also highly resistant to various solvents.
- NBR rubber roller
Other Types of rubbers used to produce rubber rollers are NBR rubbers. NBR rubber rollers are commonly used as print rollers, rollers used in the food industry, rollers used in textile printing, as rollers for industrial printers and soft rubber rollers to contact many solvents due to resistance High against solvents and so on.
Bear in mind that NBR rubber rollers do not have much resistance to ozone and should not be used in environments that have high concentrations of ozone.
- Neoprene rubber roller
These rollers are made with neoprene synthetic rubber and are usually used as soft rollers, gravure printing roller, and so on.
- Mirror roller
In general, #45 steel, alloy seamless pipe and precision welding are used to produce mirror rollers. The final level processed in this roller surface degree can be up to RA0.01. Roller surface processing to the appearance of the mirror structure ensures that the roller surface is flat, sufficient balance, non-roundness, coaxial degree etc. for different purposes.
5- The advantages of rubber rollers of the Vulcan Industrial Group
A. Raw material
- base Roller
In order to produce rubber rollers, the Vulcan Industrial Group uses #45 steel or #20steel Seamless pipe. At the same time, customers can ask us for reasonable thickness base roller designed for the ultimate in their products.
Unlike some manufacturers of the Vulcan Industrial Group, they do not reduce the thickness of the steel pipe to make the final price of rollers cheaper. The rollers have not met the standard parameters in any way.
Buy the best rubbers from Germany and the United States and combine them with the most modern machines in our factory. The technology we use to create the desired mix of customers is the most sophisticated and advanced technology available.
Rubber coating in the industrial group of Vulcan are applied on the base of the base layer by layer, and then this rubber is vulcanizing from green rubber into a mature rubber.
While some roller companies use sheet coating technology, they put the rubbers in cold processing on the roller base, which creates adhesion.
B. The process of producing rubber roller
- Dynamic balancing
In order to guarantee the effectiveness of the use of the shaft head, each rubber roller is placed in a dynamic balancing test twice.
- Hot charging techniques
To make sure that the shaft head is mounted firmly and quality in place, we use a technique called Hot Charge Technique to install the shaft head and then weld it after contraction. This is while other manufacturers weld the shaft head directly onto the rubber roller
