  • Detail

The subject of advanced polybutylene was selected into the support plan. The key technology development and industrialization demonstration subject of advanced polybutylene-1 synthesis presided over by Professor He Aihua, School of polymer science and engineering, Qingdao University of science and technology, was recently approved as the subject of the "12th Five Year Plan" National Science and technology support plan. It is reported that this subject is one of the sub subjects of the key project of the national science and technology support plan - the development of key technologies for the preparation of high-performance polyolefin special resins

it is reported that Qingdao University of science and technology will cooperate with Shandong Dongfang Hongye Chemical Co., Ltd. and plan to build the first domestic polybutylene production demonstration line in Shouguang City in 2014 through three years of research and development, forming a 10000 ton production capacity and producing new polybutylene products for building pipes and floor heating pipes

jiangpingping, Professor of the school of chemistry and materials engineering, Nanjing University, Jujiang, told China National Chemical News that the raw material of butene is butene-1 component in liquefied gas. Since there was no polybutene product in China before, this component was mainly burned as liquefied gas. According to rough statistics, there were about 2.6 million tons of butene resources in China in 2010, of which only a small amount (less than 5%) was used for the synthesis of linear low density polyethylene (LLDPE), and most of the remaining butene was used as liquefied gas

according to the introduction of Professor He Aihua, the project leader, advanced polybutylene is a very special polyolefin material, which has excellent heat creep resistance and stress cracking resistance. Its heat creep resistance is obviously better than that of polypropylene and polyethylene, which are not easy to use, and can be used for a long time at 95 ℃. It is mainly used in industrial and civil cold and hot water pipes and their accessories. It is the best floor heating pipe material. At present, China's polybutylene is completely dependent on imports. Before the application of many data, it is necessary to detect various specifications. The price of high-grade polybutylene that can be used for warming is 30000-40000 yuan/ton
