Industrial FFP2 dust mask is a professional type of mask,which is an important barrier to protect workers in coal mines, smelting and chemical industries.Therefore,industrial dust masks have a complete set of national standards and protection grade standards.
All dust masks must meet the basic standards before they can be called qualified industrial dust masks.Next, follow Jin Haocheng dust mask manufacturers to understand.
Basic standard of industrial dust respirator:
The material of the dust mask must be non-irritating and non-allergic to the skin,and the filter material is harmless to human body.The structure of the dust mask should be convenient to use;The filtration efficiency of the dust mask (dust resistance rate),the dust resistance rate of the particle diameter less than 5 micron must be greater than 90%,the dust resistance rate of the particle diameter less than 2 micron must be greater than 70%,and so on.
Standard for grade of industrial dust respirator:
The standard of dust masks is divided into oil dust mask P class and non oil dust mask N class;And according to the performance of the dust resistance and dust resistance rate is divided into KN90, KN95, KN100, KP90, KP95, KP100 six categories.KP type is suitable for anti-oily dust, such as paraffin, jade oil, etc.
KN type is suitable for preventing non-oily dust, such as salt, stone and so on.The larger the number in the model, the higher the dust resistance rate, the higher the dust safety factor.At the time of purchase, the required mask should be selected according to different dust concentrations in the environment.
GB2626-2006 also stipulates the standard coefficient of inspiratory resistance and expiratory resistance of dust masks.Workers should feel comfortable wearing dust masks and be able to exhale and inhale easily and without difficulty in breathing, usually at a rate of 20 breaths per minute.The constant ventilation coefficient of expiratory and inspiratory resistance is 85 L/min.
The standard also stipulates that product identification should be clear and clear,and identification should be indicated.
(1) Name and trademark (such as name of "dust mask",trademark of "labor insurance",etc.,make people clear at a glance);
(2) model (such as KN90, KN95, KP100, easy to buy to know which masks oil/or non-oil dust,dust resistance rate is high;
The implementation of standard number and year number,filter original type,dust rate type,such as 2626-2006KP90.
About masks:
1.the difference between masks:A protection level difference;B Difference of wearing mode (headwear, ear wear);C style difference (folding type,integrated into the type).
2. The protection level of mask:N95 is the American standard, KN90 and KN95 are the Chinese standard,FFP2 and FFP3 are the European standard. The specific comparison is as follows: FFP3>FFP2=N95=KN95>KN90,the higher the protection level, the better the filtering effect.
3.mask use time: mask can be reused,according to the different environment,dirty broken,should be replaced in time;Recommended for oil particulate matter,R type of cumulative use time no more than 8 hours,P type of cumulative use time no more than 40 hours.
About packaging:
For packaging,the standard also makes clear: on the minimum sales package,the following information should be marked in Chinese in a clear and durable way,or visible through transparent packaging:name,trademark;Type and model of mask;Execution standard number year number,product license number;Date of manufacture or batch number of manufacture,shelf life,etc.This helps to know if the product has expired.
