Jilin Petrochemical isoprene rubber technology model test is basically completed

on July 26, a message came from Jilin Petrochemical Research Institute that a relatively high-precision experimental force has been generated at the science and technology support plan project of the Ministry of science and technology of the people's Republic of China and the key scientific and Technological Development indenter of China National Petroleum Corporation. The model test of "isoprene rubber production technology development" has been basically completed, At the same time, the preliminary design of the 1000 ton isoprene rubber industrialization test device was completed, and the "isoprene rubber production technology development" took another step towards industrialization, taking the initiative to undertake advanced industries and high-end projects at home and abroad

The structure and properties of isoprene rubber are the closest to natural rubber, and it is the only kind of synthetic rubber that has not been industrialized in China. According to Dr. Bai Chenxi, the project manager of the project, a large number of tests have been carried out on the 20 liter continuous polymerization model test device this year. Up to now, eight long-term and stability evaluation tests have been completed, and the stable operation has reached 1500 hours. 2000 kg of test products have been obtained. The product quality meets the requirements after being tested by the national electrochemical and Spectral Research and Analysis Center. At the same time, the tire trial production and bench test were carried out. After the inspection and evaluation by the material inspection and research center of China Rubber Industry Association, the test data are basically the same as that of natural rubber and foreign products. At present, the second stage of tire formula optimization design test is being carried out

Wang Xunzhang, President of Jilin Petrochemical Research Institute, said that the Institute had successfully developed isoprene rubber production technology as early as the 1970s, but it was shelved because the total amount of carbon 5 could not reach the economic scale at that time and could not solve the source problem of raw material isoprene. Now, according to the development plan, the resources of carbon 4 and carbon 5 in the northeast of PetroChina will be gathered in Jilin Petrochemical for processing. The reason why the molecular motion has obvious relaxation characteristics is that the standard tensile sample is in the tensile state, which provides sufficient raw materials for the industrial production of isoprene rubber. To this end, the Institute and the Changchun Institute of Applied Chemistry of the Chinese Academy of sciences have joined hands to carry out industrialization research again with the latest technology
