Natural rubber price recovery to the climate, the market, natural disasters and other factors, so the price volatility; relatively speaking, waste natural rubber, waste latex products processed raw rubber latex reclaimed rubber price fluctuations small, replaceable natural Rubber production of rubber products can not only ensure the quality of rubber products, but also can significantly reduce the cost of raw materials, and can better control the cost of rubber products fluctuations. However, the use of latex reclaimed rubber production of rubber products, the bubble may be generated after curing, which is why? What should I do if I encounter such a situation?
1, latex reclaimed rubber itself is too high moisture content, resulting in powdered rubber compound caking rubber products, uneven mixing, vulcanization uneven, resulting in latex reclaimed rubber products surface bubbles; encountered such a situation, the latex regeneration Glue to take some dehydration measures, such as drying, if the moisture content is too high, it is best to return to the factory.
2, reclaimed rubber mixing, storage, use will produce moisture, the use of moisture containing latex reclaimed rubber material production of rubber products will lead to bubbles; can add a certain amount of rubber formulations in the moisture absorbent.
3, latex reclaimed rubber formulations improper design, such as too much amount of curing agent curing system design is not reasonable, resulting in reclaimed rubber products in the vulcanization process over-sulfur, under-sulfur phenomenon, resulting in the surface of recycled rubber products bubbles; Therefore, the use of latex reclaimed rubber production of rubber products need to find a professional rubber technology engineers design, adjust latex reclaimed rubber products formula.
4, latex reclaimed rubber products curing temperature is too high, leading to the formation of bubbles is an important reason, so be sure to select the appropriate curing temperature, and in the production process to strictly control the curing temperature.
5, unreasonable design of reclaimed rubber mold or mold blockage will result in latex reclaimed rubber after curing bubble, so in the production of latex reclaimed rubber products must ensure that the mold dry and tidy.
6, latex reclaimed rubber different indicators in different seasons, with the solubility of different compounds in the rubber, so if you do not adjust the reclaimed rubber formulations, it will cause the surface of recycled rubber products blistering.
It is not terrible to use the reclaimed rubber to produce bubbles. What's scary is that you do not know how to solve it.
