With an annual output of 30,000 tons of trioxane (TOX) products, it is a key raw material for the polymethoxy dimethyl ether (DMMn) project. Xinda Technology uses the patented technology of the Chinese Academy of Sciences to innovate and establish a reliable equipment operation process. The company has strategically cooperated with China's highest scientific research institution-the Lanhua Institute of Chinese Academy of Sciences, and has received strong support from Beijing Sanju Environmental Protection Group. In the research phase, we have in-depth cooperation with domestic first-class manufacturers such as Donghua Company and Shanghai Panma, researching and fighting together throughout the night, and establishing a deep friendship.

In order to succeed in the trial production, the employees of the company have worked hard. Organizers at all levels have succeeded and passed through hardships and finally see rainbows. Liao Chuan, the deputy director of the Production Technology Department and the workshop director, has been spinning in the central control room and the equipment site for more than 50 hours without complaint. Born in 1987, Liao Chuan is an excellent representative of the company's backbone and talent team. Some monitors operate continuously for 12-16 hours. They don't care about eating when they cool down. They fall asleep as soon as they get on the bus.

We loyally practice the "serious, thoughtful, meticulous, reliable, and foolproof" policy, and adopt a militarized management attitude to strictly treat this sacred and great cause! That desire to shine the sword at last made us rejoice after hearing the war, desperate for ourselves, and burned the sundial day and night. During the start-up phase, the company leaders and workshop employees worked overtime to thoroughly clean, purge, and replace the pipeline equipment. Each task was carried out four or five rounds. At the same time, long-term rigorous training has been carried out for employees to improve their operational skills. The non-standard equipment was disassembled, and personnel entered the tower to wipe dry; carefully carried out pipeline air tightness test, system startup and hot water system inspection to ensure that all conditions for safe startup were met. From technical work to physical work, Xinda's male and female employees are fighting on the front line, there is no difference. Female is weak, but self-improvement is strong. With the successful one-time feeding of trioxymethylene products, it means that my country has broken the foreign monopoly in this technology, solved the key technical bottleneck problem of the traditional sulfuric acid method for preparing trioxymethylene, and effectively avoided industrial technology risks and environmental risks.

From the formaldehyde process, the methylal process, the formaldehyde concentration process, the trioxane process, to the final high-end product, polymethoxy dimethyl ether, the five processes convey the good news of victory like a "relay run". The successful one-time trial production of the fourth process allowed all members of the company to see the dawn of the final victory, strengthen their confidence in the decisive battle, and vowed to produce high-quality polymethoxy dimethyl ether (DMMn) products in a week, which will serve the country as soon as possible.
