Low price of reclaimed rubber tire, instead of raw rubber production of rubber products can significantly reduce the cost of raw materials. However, if the use of rubber tire production hose, you may find it incredible, after all, "dark" tire reclaimed rubber is really difficult with the "black shiny" hose connected. But tire reclaimed rubber is also able to produce hoses, but tire reclaimed rubber performance and processing requirements are higher. The use of tire reclaimed rubber production hose if improper operation, there will be bubbles, how to solve it?
The use of tire reclaimed rubber production hose products, the reason why there are bubbles on the hose surface, there are four main reasons: the tire reclaimed rubber product itself is too high moisture content; vulcanization time in the production process is too long or inadequate; tire reclaim rubber hose mold temperature Excessive or mold exhaust design is not reasonable; vulcanizing agent of poor quality.
Based on the above analysis, we can solve the problem of bubbles in the tire reclaim rubber hose by the following methods:
1, when the tire reclaimed rubber product itself moisture content is too high, if conditions can be in the production of hose before the tire reclaimed rubber drying; if the hose manufacturer does not have drying equipment, you can also increase the tire reclaimed rubber mixing time, Or appropriate to add some calcium oxide, as far as possible in the rubber mixing process to consume the water; then if the tire reclaimed rubber itself is too high moisture content, it can only "back to the factory", which requires us hose manufacturers in the purchase of tires Reclaimed rubber time to choose the regular manufacturers, or can not "after-sale processing."
2, tire reclaim rubber tube production Vulcanization time is too long or too short will lead to hose blistering, so set the tire reclaim rubber hose vulcanization time, according to the tire reclaim rubber hose thickness adjustment: usually under the vulcanization conditions For 1 mm increments, the curing time is increased by 12 minutes for single side heating and 5 minutes for each additional 1 mm heating.
3, check the production hose mold exhaust design is reasonable, increase the number of exhaust and reduce the mold temperature.
4, tire reclaimed rubber production hose, vulcanizing agent products used more impurities, will lead to early decomposition of small molecules of impurities, the bubble will be generated in the residual hose, so choose a good quality vulcanizing agent is very important.
