Tianjin Petrochemical builds high-end polyethylene products

In May, we just completed the production of 600 tons of new M2650 family M2330D and M2320, followed by another 1,000 tons in June. 'On June 11, we were organizing the polyethylene plant of the olefin section of Tianjin Petrochemical. The production shift supervisor Wang Shengli told the reporter about the production of new M2650 high melt index products.

Tianjin Petrochemical utilizes the independently developed gas-liquid fluidized bed polyethylene process technology to make the M2650 high melt index new product 'Tian Ding' imported, and the family is continuously expanding.

High-end products account for over 40%

The high-strength, competitive product M2650 of Tianjin Petrochemical's olefins division achieved normal production at high loads. As of April 28, a special resin M2650 with butene-1 as a comonomer was produced from a polyethylene plant and produced a total of 247 hours. The output exceeded 3,500. Tons, the average load reached 14.4 tons/hour, reaching the industry leading level.

Tianjin Petrochemical M2650 products are unique in domestic linear polyethylene products. They have been deeply loved by users for their stable quality. They are widely used in the production of masterbatch and artificial flower and grass molding products. At present, sales volume accounts for more than 70% of the domestic market. Compared with ordinary materials. , Production of M2650 products benefit more than 500 yuan per ton.

In the trial production of the product, a series of measures have been adopted, such as optimizing the catalyst formulation and reaction parameters, and increasing the load of the granulator unit, in view of the fact that the melt index reaches 10 times the number of conventional products, making continuous production more difficult. Reducing the production process of blocks. In the first five months of this year, the M2650 output reached more than 40% of the total polyethylene products, with significant effect. The first batch of products were exported to Japan for the first time at the beginning of the year, and the second batch of products were also exported. Has been implemented.

New product development 'fast'

“Whoever develops new products first, it will occupy market opportunities. ' This is often the word that hangs on the new product development technician Cui Yuhui. It is with this advanced sense of development that the M2650 product she participated in was the earliest. Domestic industrial production has ended the era of long-term dependence on imports.

A domestic user has always loved to use M2650 products. Suddenly the order volume has shrunk. Originally they were in urgent need of raw materials with higher melt index to enhance their own product competitiveness. Due to high technical content, production is difficult, and no domestic manufacturers can produce If imported materials are used, not only the purchase cycle is long, but also the cost is high. After knowing this information, the technical staff of Tianjin Petrochemical's olefin department immediately formulated a new product development plan and developed a new 2790D product with a higher melt index, which solved the urgent need for users. .

The new product is good, but it is not easy to develop. In the process of developing the 2790D, the biggest difficulty is that it is difficult to switch, and the key is that the melt index spans a great deal. In this regard, they optimize product cuts by continuously optimizing the product switching sequence. The load ensures the strength and appearance of the product.

Today, Tianjin Petrochemical's olefins department persists in innovation, overcomes technical difficulties such as complicated production processes and difficult control, and has successively developed series of products with different melt index, such as 2790D, M2320, and M2330D, and has become the only company in China that produces such injection molding products.

Seamless docking to meet demand

In order to seamlessly connect new products with the market, Tianjin Petrochemical's olefins department organizers visited the market to collect information. They combined sales companies after market research and found that with the current more mature technology level, more M2650s can be developed and more developed at the same time. Melt index slightly lower series of products to meet the needs of different users of personalized processing.

In March of this year, the M2650 family's new M2330D and M2320 products with a lower melt index came into being. They became 'Cape Clam' after listing, and at the same time, the output of the M2650 family exceeded 22,000 tons, which was a 13% increase from the same period last year. M2330D and M2320 annual production and sales volume can reach 5,000 tons.
