JUST ONE. Definition of Mask:
Hide is worn around smell and mouth for filtering air export nose, as a way to achieve blocking harmful un wanted gas, dust, droplets out belonging to the wearer's nose and mouth appliances. The general medical surgical mask incorporates a three-layer structure, the external layer is resistant in order to liquid splashes, the middle layer is usually a barrier against bacteria, the inner layer absorbs dampness and moisture released by the wearer, and the nasal area is fixed by the aluminum strip. The working principle of the mask filtering particles is always to use different interception options for particles of different dimensions, such as inertial impaction, interception, diffusion, and also electrostatic attraction.



2. Method of Face Masks:
2-1. Group by shape: Masks are usually divided into three sorts: flat type, folding type and cup shape in accordance with the shape. Flat-type masks are easy to sling, but have poor adhesion; folding masks are easy to hold; cup-shaped breathing space will be large, but not convenient to transport.



2-2. Classification by sporting style:

(1) Head-mounted: suitable for workshop workers who wear for a long period, which is troublesome in order to wear.

(2) Ear-worn style: easy to wear, suitable for frequent putting on and taking off.

(3) Neck-worn form: S-hook and some soft material connectors are widely-used to convert the ear straps right neck-band type suitable regarding long-term wear, which is more convenient for workshop workers being dressed in hard hats or shielding clothing.



2-3. Classification simply by materials used:

(1) Gauze Encounter Masks: There are even now some workshops that employ gauze masks, but the GB1908 4-2003 standards they follow stick to lower requirements and do not meet the standards of GB2626-2019. It can merely protect large particles involving dust.

(2) Non-woven Encounter Masks: Most disposable defensive masks are non-woven markers, which are mainly based on physical filtration supplemented by simply electrostatic adsorption.

(3) Silk cotton Face Masks: The cotton face mask only is known for a warming effect without filtering the tiny particles such as PM2. YOUR FIVE.

(4) Paper Face Masks: suitable for food, beauty along with industries, with good air flow permeability, easy to use and comfortable, etc. Your paper used follows GB / T 22927-2008 regular.



2-4．Classification by scope associated with application:

(1) Medical masks: There are three kinds in China: medical everyday masks, medical surgical goggles, and medical protective goggles.

(2) Particulate protective markers: Industrial use complies with GB 2626-2019 standard, special labor protection equipment security mark certification (LA certification), throughout 2015 from mandatory recognition to voluntary certification. If it truly is used for anti-fog and also haze, it needs make use of the insert type, which often must meet the GIGABITE / T 32610-2016 ordinary. Civil use complies by using GB / T 32610-2016 common.

(3) Warm cloth markers: Warm masks, suitable pertaining to winter wear, only should meet the relevant criteria of fabrics.

(4) Alternative special industries: such seeing that chemical industry.



2-5. In line with protection level (See the next chart):

Different countries plus different industries have produced different standards, which are divided in to different protection levels based on different particle filtration efficiency. At present, the major standards of Chinese deal with masks include:

1. GIGABITE / T 32610-2016 《Daily Protective Face Mask Technical Specifications》

3. GB 2626-2006 or GIGABITE 2626-2019《Respiratory Protective Equipment, Self-priming Filter Anti-particulate Respirator》

3. YY 0469-2011《Medical Operative Face Masks Technical Requirements》

4. YY/T 0969-2013《Medical Face Mask for One-time Use》

FIVE. GB 19083-2010《Technical Requirements for Medical Protective Face Masks》



So currently it has divided into three types: Daily Protection, Labor Safeguards, Medical Protection.
