At the results appraisal meeting hosted by the China Chemical Industry Association, the application technology project of the EB pre-vulcanization unit completed by Shuangqian Group and Wuhan Jiurui Electric Co., Ltd. in the all-steel radial tire was approved. According to the review experts, the project has filled the application gap of China's electron beam pre-vulcanization equipment in all-steel radial tires, and the technology has reached domestic leading and international advanced level.
Shuangqian Group is the first tire listed company in China and plays an important role in the tire industry. Wuhan Jiurui Electric Co., Ltd. is the only high-tech enterprise in China that specializes in the research and development of EB pre-vulcanization equipment and its application technology. With the joint efforts of both parties, the country's first EB pre-vulcanization unit and its application technology have been successfully applied in the all-steel radial tire production line of Shuangqian Group (Jiangsu) Tire Co., Ltd.
According to reports, EB pre-vulcanization technology has been widely used in the foreign tire industry, and is one of the core technologies for green tire production. The technology acts on the tire components through the high-energy electron beam excited by the EB pre-vulcanization device, thereby activating the rubber macromolecules in the rubber compound, generating active radicals of the rubber macromolecules, further causing CC bond cross-linking between the rubber macromolecules to form a three-dimensional network. Structure to achieve the purpose of improving the physical and mechanical properties of tire components. However, EB pre-vulcanization technology has long been monopolized by foreign companies, and equipment procurement and operating costs are extremely high.
Foreign companies have also adopted confidential measures for domestic tire companies, which has made it difficult for EB pre-vulcanization process to be applied in domestic tire companies and generate benefits. The lack of EB pre-vulcanization process limits the technological upgrading and industrial development of the domestic tire manufacturing industry.
Currently, nearly 60 EB vulcanization units have been used in tire production worldwide. Goodyear, the largest tire manufacturing company in the United States, uses EB pre-vulcanization technology in tire production, American Baolanshan Tire Company, Firestone Company, French Michelin Company, Continental Tire Company, and Japanese Bridgestone Tire The company and tire companies in Korea, the Philippines, Indonesia, Brazil and other countries have also adopted electron beam radiation technology.
After years of independent research and development, and combined with the production status of domestic tire companies, Wuhan Jiurui Electric Co., Ltd. has developed a new generation of domestic EB pre-vulcanization equipment with completely independent intellectual property rights. In 2013, the domestic EB pre-vulcanization unit was successfully applied in the semi-steel radial tire production line. In 2014, the company cooperated with Shuangqian Group to carry out research on EB pre-vulcanization application technology in the field of all-steel radial tire manufacturing, and achieved success.
In the actual production process, after multiple batches and long-time operation testing, the performance of the EB pre-vulcanization device is better than that of similar foreign devices. The tire product testing data is superior to the national standard, and the key performance indicators are improved by more than 30%, far exceeding expectations. aims. Some tire companies have expressed strong interest in the application of EB pre-vulcanization technology.
