Zhongke Refinery successfully produced polypropylene biaxially oriented film material

 On July 15, Zhongke Refinery's 350,000 tons/year polypropylene plant successfully produced 1,000 tons of biaxially oriented film products, which further enriched the structure of random copolymer series polypropylene products
.

The biaxially oriented film material has the characteristics of non-toxic, tasteless, moisture-proof and beautiful, and is known as the "Queen of Packaging"
.
The new products produced by Zhongke Refinery can be used in the fields of high value-added packaging films such as food matt film and cigarette film packaging, and have broad market prospects
.

Zhongke Refining and Chemical Co.
, Ltd.
has repeatedly researched the formulation of additives, key product parameters, and brand switching plans in cooperation with Beihua Research Institute for many times.
This year, they jointly visited twice to listen to the opinions of major customers in Foshan and Shantou, identify production process risks in advance and formulate countermeasures.
measures
.
In the production of biaxially oriented film materials, the two loop reactors must be fed with different proportions of hydrogen, which is difficult to control
.
In order to accurately judge the polymerization reaction of hydrogen in one loop, the plant process engineer wrote a "one-point lesson" for sampling at the bottom of one loop in advance, refined the operation steps, analyzed potential safety hazards, and guided the team to carry out sampling and replacement operations
.
At the same time, use the sub-class to carry out training to strengthen the operation skills of the team
.
In order to avoid the production of sticking materials and reduce fish eyes, the regional technicians carried out the operation of changing the screen and replacing the cutter of the screen changer of the extruder to ensure that the product reaches the high-quality level
.

During the conversion process, the plant management personnel will follow the whole process and provide technical guidance in a timely manner; the internal operation predicts the reaction situation in advance, adjusts the density and circulating water volume in time to ensure the stable and controllable polymerization reaction, and corrects it according to the melt index of powder and pellets and the ethylene bonding ratio.
Formula parameters; team members increase inspection efforts, sample each sampling point in time, pay close attention to the appearance of products, and ensure product quality
