Nuclear technology begins to be used in tire manufacturing
At present, the well-known nuclear technology applications are mostly nuclear weapons and nuclear power plants for military applications.
However, relevant experts from the Chinese Academy of Sciences recently said that in fact, the application of nuclear technology is also "light industry", including industry, agriculture, medicine, environmental protection, public safety and Other fields.
There is a non-powered nuclear technology that can be used in many industries, called "isotope and radiation technology", that is, irradiation technology.
Zhao Wenyan is the main expert of Kefu Special Materials Co., Ltd. under the Chinese Academy of Sciences, and one of the founders and promoters of the domestic irradiation processing business.
The company's next goal is to lock in tire irradiation pre-vulcanization technology.
According to reports, the technology irradiates the semi-finished parts of the tire through the high-energy electron beam emitted by the accelerator, which promotes the cross-linking reaction of the rubber compound, which can effectively improve the rubber performance and enhance the strength.
With this technology, the rubber is uniformly stressed and expanded in the molding and vulcanization process, and the shape and size stability of the semi-finished parts can be maintained in the subsequent production process.
According to the data, some large foreign tire manufacturers have adopted this technology in the production of passenger car radial tires, and its penetration rate in Japan has reached 91%.
"We found the Development and Reform Commission before, and applied for 8 million yuan to start the fund. Later, we went to the Japanese company for inspection." Zhao Wenyan said.
However, tire irradiation pre-vulcanization technology was not accepted by domestic companies at the beginning.
“In 2007, at a forum in Qingdao, I made a half-hour report to tire companies from all over the country. But the response was very small.â€
Zhao Wenyan still remembers that only one or two companies participated in the discussion. The chief engineers of some large tire companies directly refused: 'I have worked on tires for a lifetime, and I have never heard of irradiation technology. '"
Chen Dianhua, former secretary general of the China Association of Isotope and Radiation Industry, also said: "In the process of promoting the industrialization of nuclear technology, we did find that many enterprises, especially state-owned enterprises, are very occluded and unwilling to contact new technologies, so the resistance is great."
“We used to talk about cooperation with a medium-sized tire factory, but we met with the company. The new leader heard that it was necessary to cut a section of the entire assembly line for technical transformation, and it needed to stop production for a while and then back down.†Institute of Chinese Academy of Sciences Chief engineer Huang Zhengxin recalled.
It is reported that although the radiation processing technology has developed rapidly in recent years, its application and promotion in domestic industrialization is not smooth. The cooperation between the Chinese Academy of Sciences and some tire companies has finally disappeared.
