The quality improvement of Sino-Korea Petrochemical No. 3 polypropylene plant has achieved remarkable results

From January to June this year, Sino-Korea Petrochemical's No.
3 polypropylene plant produced 134,000 tons of 14 grades of polypropylene products, including more than 50,000 tons of new products and 24,000 tons of special materials, with an annual excellence rate of 94%
.
The three high melting index grades of M30RH and HCPP series are all produced for the first time, which enriches the product variety
.

During the production of HCPP series products, the personnel of the No.
3 polypropylene unit carefully controlled the problems such as frequent blockage of the catalyst online mixer and sudden pressure drop in the catalyst system receiving stage
.
In view of the difficulties such as the rapid wear of the cutter during the production of high-melting index grades and the easy generation of trailing particles during the adjustment process, the installation technicians and experts continued to explore the control method of the cutter and pelletizing, and successfully used the high-melting index product for the first time
.
At the same time, the device strictly controls product quality, checks product quality parameters every day, compares LIMES data, and retrospectively analyzes parameter trends
.
The team members strictly implement the production process indicators of each product brand, and the normal production sampling frequency is restored after cutting the brand for 3 consecutive points to ensure that the product quality is qualified
.
In the research and development of the new brand, the process indicators are controlled smoothly, and the product quality meets the expected requirements, which promotes the product diversity and quality upgrade of the device
