On April 24, Lanzhou Petrochemical Ethylene Plant successfully developed and produced a new product of polypropylene transparent material RPE60I.
The 300,000-ton/year polypropylene plant produced 60 g/10 minutes high melting index transparent material for the first time, and realized the main catalyst for the first time in the production process.
All localized
.
The development and production of this new brand has played a role in technical reserve and market development for the diversification of transparent materials
.
RPE60I is a high fluidity and high transparency random copolymer polypropylene, which can be used to make milk tea cups and large sorting boxes
.
The ethylene plant strictly implements the "one product, one policy" new product production plan and whole-process control, compares key indicators such as melt index and haze of the product, continuously optimizes the conversion plan, route and control range of operating parameters, and organizes all employees to learn the operation process The key steps and difficulties in the process of production transfer, deduce and predict the problems that may be encountered in the process of production conversion, and formulate emergency measures to ensure the successful development of new products
.
The melt index span before and after the production conversion is large, and the target product has a high melt index, which is a challenge for the stable operation of the extruder
.
