In textile machinery, rubber parts produced with nitrile rubber as the main raw material have the characteristics of high oil resistance, good elasticity, high strength, wear resistance, and aging resistance. At present, they are more and more widely used in various textile machinery and equipment. Nitrile reclaimed rubber is processed from waste nitrile rubber products such as waterlogged nitrile and waste nitrile gloves. (textile rubber rollers, aprons, etc.), effectively reducing the cost of raw materials on the premise of ensuring product quality.
1. Application skills of nitrile reclaimed rubber in textile rubber rollers
The textile rubber roller with nitrile rubber as the main raw material not only has excellent oil resistance, but also has good antistatic performance, which can effectively prevent the spinning, tearing and entanglement. In actual production, nitrile reclaimed rubber can be used together with nitrile rubber in a suitable proportion to produce textile rubber rollers, or nitrile rubber and polyvinyl chloride resin can be used together; sulfur vulcanization, carbon black, white, etc. are generally recommended for rubber accessories. Carbon black reinforcement, clay filling, chemical plasticizers such as DBP, DBS, etc. are used to improve the process performance of the rubber compound. If necessary, an appropriate amount of antistatic agent can be added to coordinate the relationship among the physical properties of the rubber roller.
When nitrile reclaimed rubber or nitrile rubber/reclaimed rubber is used to produce textile cots, the elasticity of the cots affects the spinning quality, the hardness of the cots determines its ability to hold fibers, and the antistatic properties determine the spinning process. The excellent anti-circling resistance, and excellent wear resistance and aging resistance ensure that the rubber roller is fundamental to the spinning stability and service cycle. Therefore, when the textile rubber roller uses nitrile reclaimed rubber to reduce the cost, it is necessary to choose the appropriate nitrile reclaimed rubber product, design the formula reasonably, control each production process, and ensure the performance and life of the textile rubber roller.
2. Application skills of nitrile reclaimed rubber in textile aprons
The textile aprons used in textile machinery and equipment generally require that the inner and outer layers have good wear resistance, oil resistance, flex resistance, ozone resistance and antistatic properties, etc., without migration and pollution. Among them, the outer rubber of the textile rubber drafting aprons requires a certain friction coefficient, and the inner rubber requires a lower friction coefficient and higher hardness; dip pin.
In actual production, nitrile reclaimed rubber can be used alone in the production of textile aprons, and can be used in combination with nitrile raw rubber, or blended with nitrile rubber, nitrile reclaimed rubber and PVC. When using nitrile reclaimed rubber 2ELYY613 to produce low-cost textile aprons, it is recommended to use sulfur vulcanization, in conjunction with accelerator M, accelerator DM, etc.; among which, white carbon black and acetylene carbon black can be used in the reinforcement and filling system of the inner layer of the textile aprons , It is recommended to use white carbon black, light calcium, etc. for the outer layer; for softening and plasticizing systems, chemical plasticizers such as plasticizer DBP can be used.
In actual production, nitrile reclaimed rubber can also be used in the production of other textile rubber products. Most of the time, it will be used together with nitrile raw rubber. Later, the editor will continue to share with you various types of nitrile reclaimed rubber production textile machinery and equipment. Practical formulations of rubber parts and related issues such as the usage and dosage of specific compounding agents.
