The hottest new high-end melt blown cloth unit in

China's new high-end melt blown cloth units have been put into operation, overcoming difficulties in mechanical design and technology integration

according to the science and Technology Bureau of Wujin District, Changzhou City, Jiangsu Province, the first two sets of new high-end melt blown cloth units independently developed by China have been put into normal operation in Beijing Yanshan Petrochemical Company. Yu Keli, chairman of Changzhou Wujin Guangyu flower roller machinery Co., Ltd., said that the overall production technology of the unit has reached the international advanced level and can replace the production technology and equipment of similar foreign medical protective equipment raw materials

as a filter material, melt blown cloth has complex production process and great technical difficulty. In the past, China's high-end melt blown non-woven fabric equipment and melt blown fabric for medical protection have been subject to technical blockade and market monopoly for a long time. The high homogeneity of domestic original products, high production costs and lack of market competitiveness have seriously restricted the development of the domestic non-woven fabric industry, and it is even more difficult to meet the special needs of medical protection

it is understood that the self-developed melt blown cloth unit for medical protection products has overcome the difficulties in mechanical design and technical integration. Compared with the original market products, it has the characteristics of high degree of automation, strong production capacity, stable product quality and so on. The medical protection products produced can effectively prevent the infection of viruses, and are recognized as the first (set) major equipment products in Jiangsu Province in 2019

according to the introduction, Sinopec decided to take advantage of its own raw material production advantages in view of the shortage of key raw materials for masks. Among them, Beijing Yanshan Petrochemical focused on building two melt blown fabric production lines and three spunbonded fabric production lines. On February 21, after receiving the urgent production task of the project equipment, Guangyu flower roller machinery Co., Ltd. immediately notified all scientific researchers and key front-line technical workers to resume work, mobilized internal and external technical production forces, optimized the production process, and spared no effort to catch up with the key core equipment of melt blown non-woven unit devices, such as forming machine, Winder, Slitter, etc

on March 3, the first batch of 2 sets of melt blown cloth units were transported to the Yanshan Petrochemical Project site for installation, and the commissioning of the whole production line was completed on March 5, ensuring the smooth production on March 8. Yu Keli said that at present, Yanshan Petrochemical has reached the daily production capacity of 6 tons of melt blown cloth, and can produce 6million medical masks

melt blown fabric is a kind of non-woven fabric, and China is the largest non-woven fabric production and consumption country in the world, but the proportion of melt blown fabric is very low. In 2018, the annual output of all kinds of Nonwovens in China reached 593.22 tons, the production capacity of melt blown nonwovens was 83240 tons, and the actual output was 535523 tons, accounting for less than 1% of the overall nonwovens production. The production capacity is relatively limited

in addition, Hubei Xiantao, which accounts for 60% of the total output of non-woven fabrics in China and 1/4 of the global market share, was affected by the epidemic, and the production of melt blown fabrics was also affected. Therefore, at the peak of the epidemic, the national mask production capacity expanded rapidly, but 60% of China's melt blown cloth production capacity was blocked by the epidemic, which doomed to a serious imbalance between supply and demand

affected by the epidemic, the domestic demand for medical masks has reached the highest level ever. In order to meet the needs of the front line of the epidemic and the daily needs of ordinary people, all parts of the country have made great efforts to increase the production line of masks and expand the production capacity of masks. After a detailed understanding of the following information of Foxconn, you will understand that Wuling Automobile and other manufacturing enterprises have also made ineffective experiments and have transformed the production of masks

according to the national development and Reform Commission, on February 29, the daily output of masks nationwide, including ordinary masks, medical masks and N95 masks, reached 110million, and 116million, 5.2 times and 12 times that of February 1, respectively. The continuous expansion of mask production capacity means that the demand for melt blown cloth, the core raw material for the production of masks, has also increased unprecedentedly

since the demand for melt blown cloth has increased significantly, isn't it OK to produce a little more melt blown cloth? According to the data of enterprise investigation, before the epidemic, there were less than 60 enterprises producing meltblown cloth in China, while more than 40 enterprises increased during the epidemic period and more than 40 enterprises at the end of February. However, people familiar with the meltblown cloth industry said that most of these meltblown cloth manufacturers failed to start production

what are the reasons for not entering production? The production cycle of machines and equipment for producing meltblown cloth is particularly long. According to the data of Beijing Century Huibo company, it takes one and a half months for the simplest equipment capable of producing medical meltblown cloth to be delivered, while it takes three months for the production and delivery of medium-grade equipment, and half a year for the production and delivery of high-grade equipment. Therefore, judging from the delivery time, most of the new melt blown cloth manufacturers began to register and order equipment from mid to late February, and will not deliver them until the end of March. It takes time for installation, commissioning and training of employees, and they need to produce them in succession, and the faster ones will wait until after mid April

why is the production of melt blown cloth equipment so slow? This is related to the complexity of melt blown cloth production process

melt blown cloth uses high-speed hot air flow to draft the polymer melt extruded from the die spinneret hole, so as to form superfine fibers and collect them on the coagulation curtain or roller, and at the same time, they are bonded by themselves to become melt blown nonwovens

the application direction of melt blown cloth in China is narrow, which is mainly used in mask production, environmental protection materials, clothing, battery diaphragm and other products. Among them, the production of masks is the main application way of melt blown cloth

moreover, compared with other links in the mask industry chain, the production process of melt blown cloth is also the most complex one. The core link of the production line of the mask factory is the mask machine and sterilizer, and the production process is fast. The production of melt blown cloth needs to go through the continuous increase of the utilization of polyurethane waterproof coating. The melt is prepared for filtration and metering. The melt is extruded from the spinneret hole, and the melt is drawn and cooled into six processes. Finally, the medical melt blown cloth needs to undergo electret treatment to make the melt blown cloth charged and improve the adsorption and filtration capacity

to complete the above production process, mechanical equipment such as feeding machine, screw extruder, metering pump, melt blowing head assembly, air compressor, air heater, receiving device, winding device, etc. are required. Compared with mask machine, the production equipment of melt blown cloth is more complex and expensive, the volume is larger, and the floor area required by the factory is also larger

the anti shorting Research Center noted that since January, about 4000 mask factories have been added or cross industry, and about 40 melt blown cloth manufacturers have also increased. However, when it comes to melt blown cloth equipment manufacturing, no new enterprises have changed careers. These facts show that the construction of melt blown cloth equipment factories requires more investment than mask factories, which blocks most investors out of the door

it is understood that Beijing Yanshan Petrochemical has built two melt blown cloth production lines and three spunbonded cloth production lines, which can produce 4 tons of N95 melt blown cloth or 6 tons of medical flat mask melt blown cloth every day, and can produce 1.2 million N95 masks or 6 million medical flat masks. Yizheng Chemical fiber, which is expected to be completed and put into operation in the middle of April, will build 8 melt blown cloth production lines, which can produce 8 tons of N95 melt blown cloth per day, or 12 tons of medical flat mask raw materials

in fact, melt blown cloth is only a microcosm of Bayer's global textile expert team who can lead the research and development and testing of new PU coated fabrics. In China's medical industry, medical device industry and life-related peripheral industries, it has been honed in this epidemic and its strength is further growing. Including semiconductors, high-tech fields have also achieved pupation into butterflies in the process of this anti epidemic

at present, the epidemic peaks in China and the world have been completely staggered. The peak of the epidemic in China is the traditional January, which is also the month with the lowest annual sales in the past. Employees want to go home and reunite with their relatives, and their work has lost enthusiasm. Therefore, the impact of the epidemic is there, but it may not be much. After the epidemic, many Chinese companies are starting to turn on their engines to produce urgently needed products for the world
