At present, due to technical suppliers, although the chemical branch has made a lot of efforts, the perchlorethylene plant has not yet achieved production and compliance. At the suggestion of Chairman Zhu Dequan, the company combined with Tsinghua University and a team of technical experts from Mizuki Binhua Technology Co., Ltd. to conduct joint research on the perchloroethylene plant. After investigating the actual operation of the device on the spot, the team of Professor Ding Fuxin and Associate Professor Jiang Guoqiang from the Department of Chemical Engineering of Tsinghua University, and the team of General Manager Zheng Yu and Dr. Hong Ting of Binhua Mizuki analyzed the reaction system and reaction mechanism, and put forward preliminary ideas. . After the overhaul is over, the chemical branch will organize adjustments and tests of the equipment according to the suggestions put forward by experts, and strive to achieve the goal of reaching production standards as soon as possible.
