In the butyl tube to add a certain amount of butyl rubber reclaimed rubber has now become a trend, but the waste of butyl inner tube as raw material processed butyl rubber reclaimed in the air tightness, etc., to achieve both the guarantee Butyl inner tube product quality, but also reduce the cost of raw materials win-win situation. However, the use of butyl rubber production of butyl inner tube when there are many issues that need attention, such as Xiaobian want to say today package roll. If you ask what manufacturers are afraid of rubber products, rubber compound is not one of the absolute roller. Butyl in the production of the tube may also encounter this problem, then how to improve the roll of butyl inner tube roll to ensure the normal completion of the production of butyl inner tube do?
Compared with latex reclaimed rubber, the relative molecular mass distribution of butyl reclaimed rubber of butyl inner tube is relatively narrow, and the cohesive force and tensile strength are more partial Low, stress relaxation time is also shorter than latex reclaimed rubber. Therefore, in order to ensure the normal production of butyl inner tube, butyl rubber reclaimed rubber in the plastic mixing, mixing process must improve the butyl rubber reclaimed its own roll properties.
Some manufacturers use the production of butyl rubber reclaimed rubber tube manufacturers will appear rough, not wrapped roll problem. In fact, there are many reasons for this phenomenon, such as insufficient mixing time, low roll temperature, too little shearing force on the rubber compound, unreasonable chemical auxiliaries, too low a roll temperature and improper process steps and many more. Such as butyl rubber reclaimed rubber liner formula in the role of lubrication of stearic acid, softening oil, talc, paraffin and other excessive use, will lead to the phenomenon of roll off; rubber temperature is low, poor fluidity, easy roll off.
In order to ensure the normal production of butyl inner tube and improve the roll of butyl rubber reclaimed rubber requirements of rubber manufacturers from the following two considerations:
1, butyl inner tube production process. This area mainly includes butyl rubber inner tube in the production and processing of plastic mixing mixing time, roller temperature roller distance, feeding steps, etc., which write strictly controlled and cautious operation. In actual production, increasing the temperature, increasing the number of hot roller, reducing the roller distance, increase the roller speed can improve the butyl rubber reclaimed rubber tube wrapping.
2, butyl rubber reclaimed inner tube formula. The reasonable cooperation of various additives in rubber formulations has a great influence on the comprehensive performance of rubber products. In order to improve the roll of butyl rubber reclaimed rubber, manufacturers can reduce the amount of liquid lubricants, appropriate to reduce the reinforcing agent, or increase the appropriate tackifier, significantly improve the rubber package roll to ensure that the butyl under tube products Next process smoothly.
Is there any other way to improve the butyl reclaimer roll?
