[China places the sample on the lower pressing plate and applies the coating information] recently, a batch of C9 hydrogenated petroleum resin products with colorless, tasteless, high added value, good light resistance, excellent electrical insulation and good solubility have been officially offline. This is the first 10000 ton/year continuous catalytic hydrogenation unit of petroleum resin to produce hydrogenated resin in China, filling the gap in the domestic C9 hydrogenated petroleum resin and C5, C9 hydrogenated copolymer petroleum resin industry. All this stems from the technology of catalytic hydrogenation of petroleum resin to produce hydrogenated resin developed by Professor Liang Changhai of Dalian University of technology

c9 hydrogenated petroleum resin has good tackifying, compatibility and photothermal stability. It is an indispensable component in adhesives such as hot melt adhesives and pressure-sensitive adhesives. It is widely used in sanitary products, food packaging, books and periodicals binding and other industries. At present, although China can produce some C5 hydrogenated petroleum resin, C9 hydrogenated petroleum resin still depends on imports. Over the years, Professor Liang Changhai's team has developed a highly active and toxic hydrogenation catalyst and a process with a clear warming trend for the export of hydrogenation loaders in response to the key technical problems of harsh reaction conditions, many colloids and high impurities in the catalytic hydrogenation process of C9 petroleum resin. The quality of the obtained C9 hydrogenated petroleum resin is much better than that of similar domestic imported products, filling the gap in China's hydrogenated petroleum resin industry

Professor Liang Changhai's team took the hydrogenation of catalyst to prepare petroleum resin as the core technology, and jointly verified the dynamic strength and functionality of the material. Professor xuchunjian's team of Tianjin University jointly carried out the industrialized treatment method: please review whether the main motor source or communication line can be connected normally! The establishment of the Department has applied for national invention patents and has been put into operation smoothly. It is estimated that the annual GDP is about 220 million yuan, with an annual output of 20000 tons of C9 hydrogenated petroleum resin and C5, C9 hydrogenated copolymer petroleum resin
