[Comprehensive] Electric masks usher in industry standards

In the face of serious air pollution problems, products that protect the breath and purify the air emerge in an endless stream, and related problems have followed. In order to standardize the performance, quality and product specifications of electric anti-tamper masks, the preparation of the “Electric Hazard Mask” was included in the standard development plan.

Dust Hero and China Construction Research Institute jointly initiated the "electric mask" industry standard and held the first working meeting in Wuhan on 7.5th. At the same time, it invited research institutes, universities, testing institutions, manufacturing companies, etc. More than 40 participants in the field participated in the meeting.

The content of the standard will cover eight aspects: scope, normative references, terms and definitions, classification and marking, technical requirements, testing, inspection rules, packaging, marking, storage and transportation, and a method for testing the protective effect of masks and masks. Particle filter efficiency test method, mask wearing environment and precautions.

This standard applies to civil protection PM2.5 particles and dust-like electric anti-mite masks, electric anti-mite masks play an important role in protection and defense against air pollution, in order to ensure the health and safety of users and detection of electric anti-mite masks of various technologies Standards and standards set specific requirements for product materials, product structure design, intrinsic quality, filtration efficiency, noise, and information the manufacturer should provide. The preparation of the standard will effectively standardize the production of electric anti-mite masks, popularize the role of electric anti-mite masks, and help consumers choose. At the meeting, the representatives of the DaZhongXia and JianZhi announced that they would generally promote the improvement of product quality and the standard development of the industry from the following aspects.

The standard will specify:

1 Strictly control the level of mask filter materials, refer to the relevant new national standard of ordinary flood control masks, set different mask levels according to different air quality standards, emphasize the protection standards, and at the same time be non-toxic and non-hazardous, and possible for formaldehyde, dyes, microbes, etc. Detailed regulations on potential hazards to the body have been made so that the air quality in the inhaled body can reach good or above levels.

2 Mandatory regulation of manufacturer's external packaging identification, which includes basic information such as the manufacturer's name and address, specification and model, relevant standard certification, protection effect level, and implementation standard number, etc., to check whether the appearance has stains, deformation that affects use, etc.

In addition, due to the obvious difference between electric masks and traditional masks, it is necessary to study the standards in a targeted manner, such as:

1. Respiratory resistance One of the purposes of electric respirator is to improve respiratory resistance. There are clear restrictions on human respiratory resistance requirements. Can not be less than normal breathing of the human body, causing feelings of depression and discomfort.

2 Leakage rate Leakage rate is a major factor directly affecting the filtering effect of the mask. How would a mask leak be able to resist smog? The leak rate is the ratio of the simulated agent concentration leaked from the mask components including the filter element into the mask when the subject inhales, and the percentage of the simulated agent concentration in the inhaled air under the test conditions specified by the laboratory. The total leak rate The lower the adhesion, the higher the adhesion.

Conventional anti-mite masks are pros and cons, and many products do not have mandatory conformity marks. As a result, consumers are unable to find reference standards and electric masks are new upgrade products. The structural functions are more complicated, and in the market incubation stage, how to set standards, let Products reflect real value, and it is critical to obtain product use effects that make consumers satisfied.

There are reports that it takes 20 to 30 years for China to control haze pollution. Haze has become a national public hazard. This raises higher requirements for outdoor anti-fog equipment. As a new class of air purification products, electric masks must follow the principles of “market-driven, standards-first”. With the success of a new generation of electric masks, China Construction Research Institute will take further measures to promote the standardization of the electric mask industry.

Professor Dai Zizhu, Chairman of the Center for Environmental and Health-Related Product Safety at China CDC and Chairman of China Air Purification Industry Alliance, and Deng Gaofeng, Director of Low Carbon Architecture Research Center, China Academy of Building Research, were chaired by Deng Feng, Director of the Low Carbon Architecture Research Center, China Academy of Building Research. Hosting.

There have been a variety of shoddy follow-up products, disrupting the minds of consumers. The dusty heroes are willing to work together with the Construction Research Institute to standardize the electric mask market order and return to benign ecology.

It promoted the development of the entire electric mask industry, and also injected fresh energy into the air purification industry that is under the process of industrial transformation and upgrading, and will change the ecology of the entire environmental protection industry.
