China Petroleum & Chemical Corporation (hereinafter referred to as Sinopec) announced on May 9 that at 18:18 that day, with the 12th article of China Petrochemical Yizheng Chemical Fiber Co., Ltd. (hereinafter referred to as Yizheng Chemical Fiber), the annual output was 500 tons The melt-blown cloth production line was successfully put into operation. During the epidemic, two phases of 16 melt-blown cloth production lines urgently deployed by Sinopec were completed. Coupled with the 7-ton capacity of the joint venture, Sinopec’s daily melt-blown cloth capacity reached 37 tons, with a total annual capacity of more than 13,500 tons.

From the start of construction on February 24 to the full completion on May 9, Sinopec took 76 days to build the world ’s largest 10,000-ton class from scratch Meltblown cloth production base.

The meltblown cloth is the “heart” of the mask, which is used for the filter layer of masks and other medical supplies Properties, barrier properties, thermal insulation and adsorption. Since the outbreak of the New Coronary Pneumonia epidemic, masks have been tight and hard to find; masks have been tight and prices have continued to rise. On February 24 and March 9, the Sinopec Party Group decided to launch 16 melt-blown fabric production lines in Yanshan Petrochemical and Yizheng Chemical Fibers after two investigations. Since then, Yanshan Petrochemical produced the first batch of qualified meltblown fabrics late at night on March 6. Yizheng Chemical Fiber produced the first batch of excellent melt-blown fabric products on March 29, which compressed the conventional one-year construction cycle into more than one month.

According to estimates, the aforementioned total production capacity of Sinopec ’s meltblown cloth can help increase the production of more than 13.5 billion medical masks, which is equivalent to adding 9 masks per person to the entire country.
