Sinochem News News on August 6, Guangzhou Petrochemical’s polyethylene plant successfully produced 1,000 tons of ultra-high melting index PE-L M2750 products under high load with improved slurry catalysts in the condensing state, and all the products reached the premium standard.
.
The product has a melting index of 50±7g/10min, which is much higher than the normal production product's melting index of 20g/10min.
It is an ultra-high melting index product, which is mainly used for the production of color masterbatches and has a high degree of market acceptance
.
Previously, the device produced this product in a non-condensing state, using solid catalysts for low-load production
.
Since the use of solid catalysts requires stopping the catalyst feeder to deliver new catalysts, it is not conducive to production operations, and also not conducive to the stability of production and the increase of load
In order to solve the problem that the existing slurry catalyst can not meet the production of ultra-high melt index polyethylene products, based on the summary of the previous production experience and a large amount of data, Guangzhou Petrochemical technicians exchanged ideas with Beijing Research Institute of Chemical Industry and China Petrochemical Catalyst Co.
In order to ensure smooth production, the technical quality department and the equipment technicians jointly discuss the production details, formulate the production plan, optimize the process parameters, and contact the operators in advance for the problems that the powder is prone to stickiness and the powder is too fine during the production of ultra-high melting index products.
