Classification and characteristics of rubber roller :
1. NBR rubber roller
NBR rubber roller can be used as printing roller, food industry rubber roller, dyeing roller in textile printing in dustry and the soft rubber roller for contacting solvent and so on.
Note: The NBR has poor ozone resistance and the operation should be avoided in a high concentration ozone environment during processing.
2. Neoprene roller
Suitable for the soft printing roller, gravure printing roller and so on.
3. Silicone roller
High temperature resistance which can reach 200-250 degrees, and good chemical resistance,but it has low tensile strength.Silicone roller can be used in fabric heat setting, plastic heat setting embossing, calendering, photocopying and so on.
4.Polyurethane rubber
It has outstanding tensile strength wear resistance and crack resistance and good resistance to a variety of solvents.
5. Mirror roller
We generally adopt 45 # steel, alloy steel seamless pipe, precision forgings as the material.The surface of the roller finish degree can reach RA0.01. Mirror processing can ensure the roller surface flatness, balance, non-roundness, coaxial degree meet the customers’requirements.
Advantages of our rubber roller :
A.Raw materials :
1) Base roller:
We are adopting 304 or 201stainless steel, #45steel or #5 aluminum seamless pipe as the base roller.And we are adopting a reasonable thickness base roller according to customer’s drawing.
The base roller is produced by ourself , we will carry out strict dynamic balancing test and size inspection before the base roller is put into the next process. Some manufacturers will reduce the thickness of the steel pipe in order to get the price advantage.Such roller can’t meet the standards.But we won’t do that.
2)Rubber: Our rubber are all imported from Germany or the US and then we mix them in our factory.
And we only use 100% new material,not use recycled material. The main rubber coating technical we are using is winding technical. you can find the following production pictures.
While other manufacturers are using sheet coating technical,and the rubber is cold in processing and will cause adhesion problems easily.
B. Production process:
1)Dynamic balancing:
We will do 3 times of dynamic balancing test in the process of production of each rubber roller.which will ensure the using effect. In general,If it can displayed within 10g on the dynamic balancing device, it is called dynamic balancing. But we can do less than 2g.
l To make it on the base roller,2 After thermal suit,3 After vulcanization and grinding on the rubber roller .
In fact,the number of dynamic balancing is related to the using effect. For example in the printing industry,the rubber roller will have the accuracy requirements.
Its main purpose: to make the rubber roller can guarantee the balance in the work process.
