Quartet sand is mainly dry dust particles. A large number of inhalation of a large amount of inhalation will inevitably lead to pneumoconiosis, which is harmful to a lifetime. It is recommended to use KN100 or KN95-level professional masks; The division of self -suction filtration -proof particle -proof respirators, the KN100 level is the highest level of protecting non -oily particulate matter levels. KN represents anti -particulate matter, and 100 is the value of filtration efficiency. kn100: filtering efficiency: ≥99.97% kn95: Filtering efficiency: ≥95% In order to better protect, it is recommended to use the KN100 level. Very good protection. There are many brands that are commonly used in our country, with 3M, Shengbao, Baoshunan, Gao Trees and so on. Pay attention to the mask: First of all, the filtering efficiency of the mask on the particulate matter The high and low dust resistance is to the fine dust, especially the resistance efficiency of the breathing dust below 5 micrometers below For standards. Because the dust of this size can directly enter the alveoli, it has the greatest impact on human health. Secondly, the degree of tightness of the mask and the face shape . When the shape of the mask is not close to the human face, the dangerous matter in the air will enter the human respiratory tract from the same place. Then, even if you choose a mask with a good filter material. It is impossible to protect your health. Therefore, the mask must be divided into size to cope with different people, different faces, and in the process of use, they should also do some self -examination such as negative pressure testing to ensure the gas of the mask and prevent dust. Finally, the comfort of the mask: the softness of the silicone, the hardness is close to the human skin, and it is more comfortable. When choosing a mask, do not have a odor and no irritation to the skin.
Haha, choose me! There are various dust masks, and you must target different operating needs and working conditions when choosing. First, according to the concentration and toxicity of the dust. According to GB/T18664 "Selection, use and maintenance of respiratory protective supplies", as a half mask, all dust masks are suitable for environments with a professional contact limit with no more than 10 times the concentration of harmful substances, otherwise a full cover or protection level should be used Higher respiratory. If particles are highly toxic substances, carcinogens, and radioactivity, filtering materials with the highest level of filtration should be selected. If the particles are oily, be sure to choose the applicable filtering material. If the particles are needle -like fibers, such as slag cotton, asbestos, glass fiber, etc., because the dust mask cannot be washed water, the mask with tiny fibers can easily cause facial irritation and not suitable for use. For a high temperature and high humidity environment, the mask with a exhalation valve will be more comfortable. Selecting a mask that can remove ozone can be used to provide additional protection, but if the ozone concentration is higher than 10 times the occupational sanitation standard, the mask can be replaced by a mask. , Dust and poison combination filtering elements. For the environment that does not exist, but only has some odor environment, choosing a dust mask with active charcoal layer is much lighter than wearing anti -virus masks, such as some laboratory environment, but because national standards do not perform technical performance specifications on such masks, technical performance specifications When choosing, it is best to try it first to determine whether it can really effectively filter the odor. Is whether the dust mask really plays a protective role. In addition to choosing the protection function, another important choice factor is suitable. No universal design can be suitable for everyone's face shape. At present, the authentication testing of dust masks does not guarantee that the mask is suitable for each specific user. If there is leakage, pollutants in the air will enter the breathing area from the leak. The method of choosing a suitable mask is to use the right test. It uses a person's taste to use a special tool to have bitter or sweet particles. If you can still feel the taste after wearing a mask, it means that the mask is leaked. For details, please refer to GB/T18664 Introduction to the appropriate test. although the dust mask structure is simple, it is not simple. Choosing applicable and suitable masks is only the first step of protection. To really play a role in protecting, it must be used correctly. This includes not only wearing in accordance with the instructions to ensure that the position of each wearing is correct (not leaked). Insist in wearing, find signs of failure of the mask in time, and replace them in time. Different dust concentrations have different dust concentrations, different use time for each person, different dust masks of various dust masks, and different use of maintenance methods. Essence When any component of the dust mask is damaged, broken, and lost (such as nasal clips, nasal pads), and obvious feeling of feeling of increased respiratory resistance, the entire mask should be abandoned. Wezis or dustproof, any filter element should not be washed water, otherwise the filtration element will be destroyed. If you feel other uncomfortable in use, such as too tight heads and high resistance, etc., you are not allowed to change the length of the headband without authorization, or to loosen the nasal clip, etc., you should consider choosing a more comfortable mask or other types of respirators. The respirator is not only suitable for users, but also has a certain comfort and durability. It is manifested in the slow increase in respiratory resistance (large dust), light mask, headband is not easy to loosen, masks are not easy to collapse, nose or head or head With fixed firmness, no odor selection, and no irritation to the skin, etc., usually only those who have long -term use of dust masks have the most experienced and most right to speak. Therefore, it is recommended that the quartz sand factory uses at least the protective mask above N95 or above, such as 3M8210, 3M8511 and 3M8210V.
