Zhongke Refinery successfully produced new food grade polypropylene products

Recently, the 350,000-ton/year polypropylene plant of Zhongke Refinery successfully produced high-fluidity food-grade injection plastics, setting a new record for the highest operating record of resin melt index for domestic extrusion granulation units
.
This product is a random copolymer polypropylene, which has the characteristics of high transparency, good fluidity, and good balance of rigidity and toughness.
It is widely used in injection molding products such as milk tea cups and suitcases
.

Zhongke Refinery has learned through the investigation and investigation of the downstream market that high melt index products can not only improve the secondary processing efficiency of downstream manufacturers, but also save processing costs
.
With the recovery of the catering industry, the market demand for plastic injection for cups has huge potential
.
Guided by the market, they jointly developed and optimized the production parameters of the products with the Beihua Institute twice, formulated emergency plans for extruder parking and high-melt-index resin start-up, organized four teams to conduct deductions, and mastered the high-melt index polypropylene production plan.

.

During the trial production process, they strictly control the parameters and indicators, keep an eye on the operation of the extruder, and adjust the cutter speed and feed air pressure of the pelletizer in time according to the pelletizing situation to ensure product quality
.
They intensified the inspection of the extrusion granulation system to ensure the safe and normal operation of the equipment
