On May 17, Zhongke Refinery's EVA (ethylene-vinyl acetate copolymer) plant produced UE2825 solar photovoltaic material for the first time, which will help alleviate the dependence of photovoltaic materials on imports
.
In recent years, with the high-end development of the domestic photovoltaic industry, the domestic demand for high-end photovoltaic materials has increased significantly, and the import dependence is relatively high
.
The products produced this time can be used to make photovoltaic cell lamination films, elastic packaging films, heat shrinkable films, agricultural films, food packaging films, high-strength rupture-resistant bags, etc.
, and have broad market prospects

.
The production process is faced with challenges such as high vinyl acetate content, high melt index, and severe reaction.
The reaction control is difficult and the operation requirements are high
.
The technicians of the installation kept an eye on various parameters, strictly controlled key indicators such as pressure and temperature, and adjusted the melt index by increasing the injection volume of vinyl acetate and slowly increasing the injection volume of propylene
.
The internal and external operators work closely together, combined with the operating experience of similar products, always pay attention to various parameters and make adjustments in time, strengthen the appearance inspection of particles, and ensure good production results
