The rubber rollers on the market can be divided into papermaking rubber rollers, printing and dyeing rubber rollers, printing rubber rollers, grain hulling rubber rollers, metallurgical rubber rollers, mimeograph rubber rollers, etc. according to their uses. The performance requirements of rubber rollers in different applications are different, so you need to choose the right one. rubber. In actual production, natural rubber, as a traditional rubber variety, has a wide range of applications in the production of rubber rollers. So what are the characteristics of rubber rollers with natural rubber as the main raw material, and what are their specific applications in various fields? What problems should be paid attention to in the production of natural rubber rollers?
1. Natural rubber performance characteristics
Natural rubber has the characteristics of good elasticity, small deformation, abrasion resistance, and good process performance. It is the rubber with the best comprehensive physical and mechanical properties. The resilience of natural rubber can reach more than 50%-85% in the range of 0-100℃, and the normal performance can be maintained at a temperature of 130℃, and the elasticity of natural rubber can be changed to brittle substances when the temperature is lower than minus 70℃; natural rubber itself can only be resistant to some extremes. It is a kind of solvent, but it has better alkali resistance.
2. Performance characteristics of natural rubber rubber rollers
Natural rubber is an ideal raw material for the production of rubber rollers for conveying, conducting, supporting and pressing. The rubber roller produced with natural rubber as the main raw material is suitable for the environment without contact with organic solvents and strong acids; the hardness of the natural rubber roller 2YLYY98 can be controlled among the Shore A hardness of 30-100 degrees, and the use temperature is minus 50°C. 120°C above zero. The use of natural rubber together with an appropriate amount of styrene butadiene rubber, butadiene rubber, and neoprene rubber can further improve the aging resistance of the rubber roller, and is widely used in the papermaking industry, printing and dyeing industry, and stylus printers.
3. Production characteristics of natural rubber rubber rollers
Natural rubber has poor aging resistance, and the market fluctuates greatly. Therefore, many natural rubber roller manufacturers choose to use natural rubber with synthetic rubber and reclaimed rubber to further optimize product quality while improving the aging resistance of their products. The combined use of natural rubber and styrene butadiene rubber, butadiene rubber or neoprene can improve the aging resistance of the rubber and extend the service life of the rubber roller; the combined use of natural rubber, latex reclaimed rubber, and tire reclaimed rubber can improve the process performance of the rubber. Reversion to the original vulcanization, reducing costs.
Rubber rollers produced with natural rubber as the main raw material have a wide range of applications. Adding appropriate amounts of other types of rubber to natural rubber rollers can further improve the rubber roller processing technology and the overall performance of the finished product, and reduce the cost of raw materials.
