Recently, Shandong Yiteng Group, with the help of the North Century Cellulose R&D Center of Beijing Institute of Technology, has successfully broken through the incomplete alkalinization and non-uniform technology substitution in the industrialized production of PAC (polyanionic cellulose) through independent technological innovation. And the bottleneck of the process has filled the gap in domestic industrial production of PAC.
PAC is an important high-tech chemical product that has been widely used in various fields of industrial production and has been recognized internationally. However, because of its complicated technology and technical difficulties, only a few developed countries such as the United States, the United Kingdom, Japan, France, and Germany have mass production capabilities. In order to meet the needs of industrial production, China's related industries will spend hundreds of millions of dollars each year to import high prices from abroad.
Shandong Yiteng Group adopts the self-developed “ternary compound solvent” new technology to give full play to the role of each solvent, solve the technical problem of incomplete alkalization, increase the acid resistance of PAC by more than 30%, and salt tolerance. Increase by more than 20%. At the same time, they adopted a self-designed "multiple slurry" process and a dedicated reaction equipment DCS computer control system to solve the uneven replacement of this process, so that PAC production to achieve continuous mass production, production efficiency increased by 30% the above.
The PAC products developed by Teng Group have undergone trials in many industries such as petrochemical, food, medicine, cosmetic, paint, ceramics, explosives, etc. The main technical and economic indicators have reached or exceeded the level of similar foreign products, and the cost has been saved by more than 1/3. Has produced good economic and social benefits.
