Release and implementation of the world's first inactivated mask group standard release date: Source: China News Agency China Medical Materials Association released the group standard of copper containing filter half mask in Hefei, Anhui Province on the 16th, which is also the world's first inactivated mask group standard

copper containing filter half mask is a new type of inactivation mask made of copper containing non-woven fabric as the main material. It can directly contact and inactivate the comprehensive hiant service bacteria, viruses and fungi by using the anti microbial properties of copper ions. The inactivation mask not only puts forward high requirements for the form, content, product design and production process of the combination of copper ion and non-woven fabric, but also requires that the copper shedding rate must be within the safety range of human body, with high technical requirements and barriers

the group standard "filter half mask containing copper" issued this time covers the technical requirements, inspection methods, small power consumption of labels, packaging, transportation and storage rules for inactivated masks. The main standards include that the bacterial filtration efficiency is not less than 95%, the particulate filtration efficiency is not less than 90%, and the amount of copper shedding is less than 1% of the maximum tolerable intake of human body

according to huangyuhao, chairman of Anhui box Health Technology Co., Ltd., the representative of the drafting unit of the group standard of filter half face mask containing copper, there is no difference between the inactivated face mask and the ordinary face mask in appearance. The copper ion contained in the inactivated face mask can still be retained in the face mask after killing the contact bacteria, viruses and other microorganisms. Therefore, the number of times of use of the inactivated face mask can theoretically reach 60

huangyuhao said that at present, the company has developed a number of new products including copper oxide inactivation masks and polylactic acid full degradation bacteriostatic masks, which are exported to more than 10 countries and regions such as the United States, the United Kingdom, Japan and Germany

chenhongyan, Secretary General of the medical devices branch of the China Medical Materials Association, said that China is a major producer and exporter of epidemic prevention materials in the world, and all kinds of new technologies and products are constantly emerging. The formulation and release of the group standard for inactivated masks and the allocation of a wide variety of experimental accessories will improve the quality of masks and encourage enterprises to provide qualified epidemic prevention materials to the domestic and foreign markets
