Yinguang Group successfully trial-produced ton-level PDI qualified products and accelerated the localization of bio-based isocyanate

Equipment instrument maintenance, process technology improvement, test plan optimization… After a short overhaul, employees of the PDI Research Institute of Juyin Company of Yinguang Group are carrying out the second batch of PDI The distillation work of products continues to make efforts to collect test data. In early October, Yinguang Group successfully trial-produced the first batch of ton-level PDI qualified products with a purity of over 99.5%, completing the annual work target ahead of schedule and realizing the localization of PDI products, which has a positive role in promoting the development of my country’s isocyanate industry.

PDI product is a new aliphatic isocyanate whose raw material is derived from renewable biomass. It is a “new member” of the isocyanate industry. It has excellent mechanical properties, outstanding chemical stability and excellent light and weather resistance. It can be used in high-end coatings, elastics In many industrial fields such as adhesives and adhesives, relying on the unique advantages of low-carbon environmental protection, environmental friendliness and sustainable development, it meets the environmental protection requirements of upgrading, substitution, green and health, and its development prospects are favored by domestic peers.

In 2019, with the goal of achieving industrial upgrading and promoting the development of surrounding industries and local economies, Yinguang Group integrated its own technological advantages and scientific research achievement reserves, established industry-university-research strategic cooperation with universities and downstream enterprises, and jointly developed the entire bio-based PDI industry chain Manufacturing Technology. The company has established a backbone scientific research team to ensure that everyone has assessment indicators. After about a year of small trials and thousands of experiments, the kilogram-level qualified products successfully produced in 2020 were recognized by downstream users, and developed Pilot scale synthesis process technology.

In 2021, the PDI project was listed as a key civilian product development project of the Ordnance Industry Group. In order to further accelerate the pace of PDI industrialization, Yinguang Group Juyin Company established a PDI research institute in May this year and began product trial production in July. Faced with difficulties such as the difficulty of trial production, the unit established a “party member commando team” and a “three-in-one” improvement team. Through regular technical seminars, real-time tracking and collection of experimental data, 24-hour duty at the test site, conquering foreign language materials, and studying and judging risk factors in advance Analytical and control methods and other measures have been adopted, and superior resources have been concentrated to break through the core process, ensuring the safe, efficient and high-quality completion of trial production tasks.

In the next step, Yinguang Group will carry out research on the continuous phosgenation reaction technology of PDI products and product quality improvement, promote the construction of 10,000-ton PDI production equipment and market application research and development, and simultaneously explore the downstream market.
