On August 18, Yangzi Petrochemical's EVA plant was converted to new products for the first time, and successfully produced a photovoltaic film material UE 2825DV with a vinyl acetate (VA) content of 28%.
The shortage of photo film materials brought about by the rapid development has replaced some imports and further improved the competitiveness of China's photovoltaic industry
.
Yangzi Petrochemical's 100,000 tons/year EVA plant is the first production plant in Sinopec that adopts LyondellBasell's autoclave process technology.
Due to different process characteristics, it can produce photovoltaic films, hot melt adhesives and other vinyl acetate (VA) content Higher special-purpose new copolymers meet the needs of high-end products in the market, help upgrade downstream products, and reduce import dependence
.
Yangzi Petrochemical's 100,000 tons/year EVA plant is the first production plant in Sinopec that adopts LyondellBasell's autoclave process technology.
Yangzi Petrochemical's EVA plant is a high-temperature and high-pressure process, with many imported equipment, complex interlocking logic, and high process control requirements.
During the conversion process, a little carelessness will cause large fluctuations in the reaction temperature and cause ethylene to decompose.
In order to ensure the first conversion With the success of the new product, the Yangzi Petrochemical expert team has repeatedly optimized the production plan, and refined hundreds of production steps and emergency measures.
Only 118 items have been confirmed for the trial production conditions of each system.
Comprehensively rectify the problems and hidden dangers found since the start-up, strictly follow the trial production plan to implement various process instructions, and control the injection amount of regulators and initiators to ensure the smooth implementation of the trial production
