On March 14, Vice Mayor Zhao Hai, Municipal Bureau of Industry and Information Technology, Municipal Bureau of Science and Technology, Municipal Bureau of Financial Work, Nanhai District Branch, Shishan Town, District related departments, Nanhai Agricultural and Commercial Bank, Foshan Gold Control Company and other relevant leaders came to Foshan Lepton Precision M&C Tech Co., Ltd.
Vice Mayor Zhao Hai and his delegation first inspected the production site.
Subsequently, Zhao Hai, the vice mayor and the company's board of directors held a research forum.
At the symposium, General Manager Zhu Ziming reported the progress of the project "Research on the nanofiltration membrane for masks and its production line" to Vice Mayor Zhao Hai and put forward the specific problems the company is facing.
Vice Mayor Zhao Hai detailed understanding of the project situation, and with leaders at all levels of discussion solutions, put forward specific opinions, introduced the government for the outbreak of the production of mask enterprises series of policy support and related requirements, guidance with live support policy. In addition, the site coordinated to push forward the inclusion of the nanofiltration membrane and production line of masks into the catalog of emergency supplies for epidemic prevention and control as soon as possible, and promoted the process of replacing melt-blown cloth. Give priority to the support of science and technology project, accelerate the technology research and development of equipment and product iteration; Promote cooperation between upstream and downstream enterprises, provide green channels, and speed up the approval process of nanofiber filter masks.
Due to the outbreak of the global epidemic, there will be more shortage of melt-blown cloth. Nanofibers are the preferred alternative to melt-blown materials.
The core filter material of the mask produced by Qingzi Nano nanofiber production equipment has obtained the inspection report of Guangdong Provincial Institute of Medical Device Quality Supervision and Inspection and Guangzhou Medical Device Quality Supervision and Inspection Center of China Food and Drug Administration, which conforms to the standard requirements of medical surgical mask yy0469-2011.
