Traditional ordinary rubber water pipes are generally processed with natural rubber or natural rubber/styrene butadiene rubber as the main raw material. The use of reclaimed rubber in an appropriate amount can effectively reduce the cost of raw materials. Compared with processing reclaimed rubber, the production process of vulcanized rubber powder is simpler and environmentally friendly, and can be used as the main rubber material or filling material to be added to the production of water pipes. The role of vulcanized rubber powder in the production of water pipes is not limited to reducing costs, but in what aspects? What problems should be paid attention to during use?
1. The role of vulcanized rubber powder in rubber water pipes
Compared with rubber materials such as natural rubber and styrene-butadiene rubber, the price of vulcanized rubber powder is much lower. Filling the rubber water pipe can effectively reduce the cost of raw materials. In actual production, the addition of vulcanized rubber powder can also improve the process performance and use performance of the rubber, such as reducing the deformation of semi-finished products, which is conducive to exhaust, etc.; from the perspective of performance, reasonable addition of vulcanized rubber powder and stretching of rubber water pipes Indexes such as strength and elongation at break remain basically unchanged, and the fatigue resistance and crack growth resistance of vulcanizates are significantly improved.
2. Skills for selecting vulcanized rubber powder in rubber water pipes
When using vulcanized rubber powder to reduce the raw material cost of rubber water pipes and improve the process performance of rubber materials, it is recommended to use high-fineness vulcanized rubber powder (commonly used vulcanized rubber powder above 80 mesh). In theory, the higher the fineness of rubber powder 2YLYY93, the mechanical strength of rubber water pipes. The closer the rubber powder is not added, the greater the improvement in fatigue resistance of the vulcanized rubber. In actual production, the greater the fineness of the vulcanized rubber powder, the more advantageous the rubber water pipe extrusion process.
3. Mixing skills of vulcanized rubber powder in rubber water pipes
In theory, a large amount of vulcanized rubber powder can be mixed in the production of rubber water pipes with natural rubber as the main raw material. 100-200 parts of vulcanized rubber powder can be added to 100 parts of raw rubber, and the amount of vulcanizing agent, accelerator and filler in the formula can be adjusted appropriately , Which can further optimize the comprehensive indicators and performance of rubber water pipes. In actual production, not only vulcanized rubber powder can be used in rubber water pipes with natural rubber as the main raw material, but also reclaimed rubber can be added in an appropriate amount. It is recommended to use tire tread reclaimed rubber as the main material to reduce more production costs.
When using vulcanized rubber powder to reduce the production cost of rubber water pipes, improve the rubber processing technology and the performance of the finished product, rubber product manufacturers also need to appropriately adjust the production process parameters and procedures.
