The high-density polyethylene black pipe material produced by Shanghai Petrochemical is the only resin product in China that has obtained PE100+ international certification, and can be used to process into urban buried gas pipelines. It has been widely used in the national coal to gas project. In the quarter, Shanghai Petrochemical's output of this top-notch product tripled from the same period of last year and all were successfully sold, achieving a good start-to-finish for the whole year.
In order to achieve this goal, when Shanghai Petrochemical formulated the production plan at the beginning of the year, it formulated a special scheduling plan for the main polyolefin unit.
Unlike ordinary petrochemical products, plastic resin production lines usually require two or more products to be produced alternately according to market changes. In order to reduce the impact of this alternation on 'black material' production, Shanghai Petrochemical has arranged performance and 'black materials'. 'Very close to ordinary pipe material, as a 'replacement member' on a polyolefin production line.
According to the plastics department of the company, as long as a special kind of carbon black is added to this ordinary pipe material, it can be transformed into a 'black material' that is urgently needed for the 'coal-to-gas' project. Put it in the same strip as the 'black material'. With production line production, the device can flexibly determine the timing of carbon black raw material addition according to the market rhythm, and in the process of switching between the two resins, there is no intermediate transition waste. Such an arrangement not only avoids the fluctuation of the load of the device, but also ensures The 'black material' capacity is maximized.
While optimizing the scheduling plan, in response to last year's feedback from downstream pipe processing companies, the polyolefin complex has further optimized the product's technological indicators. The device director Hu Xiong said that the ratio of product yields is melted. The fine adjustment of a series of key indicators such as the index, the current production of 'black material', has improved performance over last year, can better meet the higher requirements of domestic companies, and improve downstream users' satisfaction with Shanghai Petrochemical's products. .
This “black material” resin produced by Shanghai Petrochemical uses the 'two-peak' process technology from Borealis, and uses two reactors to make the resin product perform better on the strength and toughness of the pipe material. It meets the requirements for raw material performance of buried gas pipelines in the city. It was approved by the international authoritative PE100+ industry last year. Shanghai Petrochemical is also the only domestic company that has passed this certification. In the first quarter, the company produced about 30,000 tons of 'black material'. For the "coal to gas" project being launched this spring, it provides high-quality raw materials.
