Facial fit affects dust mask performance

Pneumoconiosis is the most serious occupational disease that endangers the health of workers. Pneumoconiosis is mainly caused by inhalation of fine dust such as minerals, metals, abrasives, and carbon materials. According to relevant authoritative reports, there are nearly a million cumulative cases of pneumoconiosis and suspected pneumoconiosis cases in China. At present, there is no medical treatment that cures pneumoconiosis. Therefore, it is necessary to prevent operators from being harmed. Wearing respiratory protective equipment is the most limited protection measure. . Selecting the right respiratory protection device becomes the key.

At present, China has a number of manufacturers producing dust masks and gas masks. At the 84th China (International) Labor Protection Products Fair, nearly 40 respiratory protection companies participated in the exhibition. Moreover, foreign brands such as 3M also entered China, enriching the respiratory protection product market in China. So, in the face of these numerous product brands, how do consumers choose?

If the dust mask does not conform well with the user's face, harmful substances will leak through the gap between the mask and the face, and the protection function will be greatly reduced. Shao Yizheng, Business Manager of West Japan Trading (Shanghai) Co., Ltd., inspected the fit of the dust mask on site at its booth. According to the inspection of the equipment, the leakage rate of the product is only about 2%. According to Shao Yijun, the unique 3D rubber edge design of the Hing Yan Mask greatly improves the consistency of the product with the face.

West Japan Trade is the general agent of Japan Research Co., Ltd. in China. The company's products are imported from Japan. Talk about the sales of imported products in China. Shao Yijun disclosed that because the products are imported from Japan, the prices are relatively high, and some are even 20 times higher than domestic products. This makes the product can not be more accepted by domestic enterprises. In addition, the research and development of masks in Japan has gained greater popularity. Therefore, the company's products are used in Japanese-funded enterprises in China.

According to reports, Hing Yan masks use a filter made of electrostatically charged wool. The strong electrostatic force and the three-layered structure of the gap layer between the two trapping layers achieve a low fiber density, resulting in a high catch. The dual effect of efficiency and low suction resistance. “Xingyan masks are the only products that use wool as a filter element,” Shao Yixi said.
