Original title: See the comparative test results of 45 medical disposable protective suit and isolation gowns here. Protective suit are generally only used in medical treatment, and ordinary consumers seldom know and buy such products. Since 2020, the novel coronavirus epidemic has been raging around the world, and China's anti-epidemic work has also won a decisive victory. With the normalization of epidemic pngbiao Testing and Certification Co., Ltd. to carry out comparative tests on 45 disposable medical protective suit and isolation clothing commodities (the results were only responsible for the samples). Basic information Source of the sample The comparative test samples were randomly purchased by the staff of Heilongjiang Consumer Association as ordinary consumers in medical supplies stores in Harbin and online shopping platforms including Tianmao, Jingdong, Suning and Vipshop. Among them, there were 27 samples of disposable medical 8.15-2018 Textiles Test Methods for Nonwovens Part 15: Determination of Air Permeability (see Figure 1). Expand the full text Figure 1 Assessment Dimensions Disposable medical protective suit are quite different from isolation gowns in terms of performance moisture resistance Surface moisture resistance reflects the ability of water droplets to roll down the surface of the protective suit, and is evaluated by the water contact grade on the outer surface of the protective suit. The sample is sprayed with a certain amount of experimental water, and the appearance of the sample after the test is compared with the evaluation standard and the identification film to determine its water level. 4. Resistance to water penetration Aiming at the medical protective suit detection,free shipping disposable coverall, the water pressure test is carried out on the medical protective suit at a certain boosting speed to check whether there is water seepage in the medical protective suit. 5. Moisture permeability Moisture permeability reflects the permeabilityliquid barrier) Protective performance is the core function of medical protective suit, which mainly includes the filtering efficiency of protective suit to particulate matter in the air and the barrier to blood, body fluids and other secretions. The test results show that: The 27 types of disposable medical protective suit can effectively filter particles in the air, and the filtering efficiency is above 90%; the liquid barrier performance varies among individuals, but they all meet the standard requirements and have excellent performance. Among the 18 kinds of isolation clothing, only 4 kinds had filtration efficiency ≥ 70%,KN95 Mask with Fast Shipping, which met the standard requirements of disposable medical protective suit; 3 kinds of samples did not meet the standard requirements of water permeability and synthetic blood penetration resistance, and only the results of surface moisture resistance test had no sve suit does not meet the standard requirements, and the fabric is easy to break during use or wearing and taking off, which increases the risk of virus infection: 2. The breaking strength does not meet the standard requirements Comfort performance (moisture permeability, air permeability) In order to enhance the protective effect, protective suit fabrics are usually laminated or coated, Medical Disposable Coverall ,Against Bacteria Breathable KN95 Face Mask, which are thick and have poor air permeability and moisture permeability, which greatly increases the user's stuffy feeling when wearing, and ler; ③ Grasp the opening of the waist zipper of the protective suit while holding the one-piece cap and sleeve of the protective suit with both hands to avoid contact with the ground; ④ Put on the lower garment first, then the upper garment, pull the zipper to the chest,KN95 Face Mask, buckle the one-piece cap on the head, and seal the zipper buckle after all the zippers are closed.
