dust maskIt is a kind of personal protective equipment, which can prevent or reduce the dust in the air from entering the human respiratory organs, so as to protect life safety. Dust masks come in various shapes and brands, and can be divided into three categories: "disposable masks", "replaceable half masks" and "full masks". Disposable masks:1, no breathing valve. Disposable dust masks, inhaled and exhaled through filter material, are most commonly found in industrial establishments. Most of the disposable dust masks without breathing valve are made of non-woven fabrics inside and outside, with a filter cloth in the middle; the dust filter mainly depends on the filter cloth in the middle. Because the melt-blown cloth has electrostatic properties, it can absorb positive small particles. Because dust is adsorbed on the filter cloth, the filter cloth cannot be washed by static electricity, so the dust mask is disposable. 2, with exhalation valve. Disposable dust mask for independent inhalation and exhalation. Applicable environment: It can be used in food processing, catering service, metal stamping, motorcycle riding, electronic manufacturing, dust-free workshop, electroplating, electric welding floor, school, environmental cleaning, handicraft industry, spray processing, beauty, pharmaceutical, public places and other purposes. How to use: Put the elastic earhooks on both ears, match the full nose style, and press gently.
Can be changedChange the dust mask:It is a self-priming filter dustproof mask composed of a dust filter element, an exhalation valve, an inhalation valve, a headband, a half mask, etc. The inspiratory and expiratory channels are separate. Scope of application: oil and gas, smelting, coal, light industrial product manufacturing, organic chemical raw material manufacturing, non-coal mines, chemical product manufacturing, medicine, food, feed, building material manufacturing, metallurgy, construction, casting and forging, machinery manufacturing, decoration and other industries .
Comprehensive cover: Divided into active air supply type and careful filter type. It is mainly composed of filter element, cover body, eye window, exhalation communicator, headband and other parts. Applicable environment: suitable for high concentration toxic gas environment.
Facing the dusty working environment, although the company has taken some technical precautions, the dust cannot be eliminated, and employees will be hurt by the dust, so personal protection is particularly important. How to better protect employees, what kind of dust masks are effective? What should be considered when choosing a dust mask?
1. Dust masksAccording to national standards, dust masks are divided into three grades:KN100,KN95, KN90. KNRepresents dust, smoke, mist, microorganisms, etc. Values represent conservation efficiencies. The larger the value, the better the effect. Dust maskKN100 can meet various harsh dust environmental protection. Second, the airtightness of the mask must be considered. A good dust mask can be combined with the face. The sealing effect of general types of masks varies from person to person. Therefore, it is extremely important to choose dust masks of different sizes. Third, the comfort of the mask must be considered. The dust mask is recommended to be made of silicone, which is softer and more comfortable than other non-silicone materials, and is less likely to cause skin allergic reactions. Masks made of non-silicone materials are relatively hard and may easily cause facial indentations. Fourth, we must consider the smooth breathing of the mask. If you choose a dust mask with double filter cotton and double filter surface, this dust mask has low breathing resistance and good air permeability.
