Problems solved by technology

[0002] Now in the traditional industry, the dry rubber in the rubber clear is extracted from water and rubber by adding sulfur. The content of dry rubber in each ton of rubber clear is about 4%. Sulfur needs to be added for each ton of dry rubber. The cost is about 4,000 yuan, and the original technology needs to wait more than 10 hours to extract the glue after adding sulfur to extract the impurities and glue from the white glue, which reduces its production efficiency and does not meet the requirements The interests of the enterprise itself, for this reason, we propose natural rubber latex coagulation additives
