Trial production of medical film materials to help fight the epidemic

On May 6, Zhongke Refinery's 350,000-ton/year high-density polyethylene plant successfully trial-produced M1830, a new metallocene medical film material
.
The product has the advantages of high transparency, low crystal point, good toughness, and better processing performance.
It can be used to make medical protective clothing and help ensure the supply of epidemic prevention materials
.

In response to the severe domestic epidemic situation, Zhongke Refinery independently developed the new product M1830 according to market demand and when foreign patentees could not provide production experience and guiding parameters
.
In order to ensure the success of the trial production, Zhongke Refining and Chemical Co.
, Ltd.
carefully summarized the production experience, and analyzed the operation parameters of the device and the changes in the laboratory data in detail
.
Regional management technicians discuss and refine the product switching plan, formulate preventive measures for emergencies, organize team members to learn the production conversion plan in advance, and fully grasp the possible disposal of reactor scaling and CTO blockage during the production conversion process
.

M1830 is the brand with the lowest density of the device at present.
A slight fluctuation can easily lead to fouling of the reactor, and the index of powder and pellet fluctuates greatly during the switching process, which makes the production difficult
.
During the production conversion process, the plant management personnel were on duty 24 hours a day, and closely watched the reaction temperature, reaction circulation flow, axial flow pump power and other parameters with the team during the whole process, and finely adjusted the amount of hydrogen and hexene added
.
In view of the situation that the reaction temperature fluctuated greatly in the early stage of production conversion, the team took measures such as switching the raw material refining bed in time and modifying the PID parameters of the temperature-adjusting water system, and successfully produced the M1830 high-quality product
.

Since the beginning of this year, Zhongke Refinery has closely followed the market trend, strengthened communication and cooperation with Beihua Institute, Chemical Sales South China and other units, gave full play to its advantages in production, sales and research, and made every effort to do a good job in the research and development of new polyolefin grades
.
The successful trial production of this product has created conditions for Zhongke Refinery to realize the diversification of polyolefin products, seize the high-end polyolefin market, enhance brand competitiveness and increase efficiency
