The smog is getting thicker and thicker, and the mask is also upgraded.
Experts predict that this year's smog season will come earlier than in previous years, and it will be even more embarrassing. In fact, this year's smog has arrived since August, two months earlier than in previous years. How to choose an anti-fog mask, the brand seems to be the only cognition for the average user. However, when the brand sometimes has the meaning of relying on the old and selling, do not think ahead.
Today, I will introduce a series of anti-fog masks that have smashed 3M streets. I hope that this year, everyone can prevent smog more easily and not so much.
The higher the filtration, the greater the resistance, and the difficulty of sucking becomes a technical difficulty.
The most basic requirement for anti-fog is to filter PM2.5 to more than 90%, but the higher the filtration efficiency, the greater the suction resistance. Experts in the industry recognize the current production process and materials, even if it drops 10%. Resistance is a technical problem that is difficult to achieve. This point is not even solved by 3M (maybe 3M manufacturers think that their brand advantage is enough to eat, or maybe they are big companies, disdain for small breakthroughs) .
We conducted the most intuitive video test on the most important filtration efficiency of anti-fog masks. The source of the test was cigarette smoke (the particle diameter of cigarette smoke was 0.1-1 micron), which was 25-2.5 times smaller than PM2.5 (2.5 micron). The test environment is a dark room.
The test concluded that there should be no major problem in filtering 90% of cigarette smoke by visual inspection because there is no corresponding test equipment in the industry.
Crusader electrostatic adsorption, easy breathing
First of all, we can understand the filtering principle of general anti-fog masks on the market through a picture.
As can be seen from the above figure, inertial collision, agglomeration interception, and adsorption effect must achieve “passive filtration†with fiber density. If the filtration efficiency is 100% dependent on fiber density, the suction resistance will be infinite, just like taking A piece of glass can't suck at all.
Then, the only way to achieve filtration without relying on fiber density is "active adsorption" by static electricity. But the difficulty is that the mask is not a large capacitor and can store static electricity for a long time. Moreover, static electricity will gradually decay when it meets water or within a certain period of time, and is infinitely close to zero. That is to say, when the static electricity is completely attenuated and there is no "passive filtration" of the material, the mask is also vacant.
Crusader friction charging, perfect for power storage
Obviously, the capacitor can save more charge because of the particularity of the material, then the core filter material of the mask needs to be infinitely close to the characteristics of the capacitor material to achieve the purpose of injecting more static electricity. The particles in the air are all charged, and the longer the use will neutralize the mask charge, the static electricity is continuously reduced, and the static electricity itself is continuously attenuated due to various factors.
Solution: The core filter material invested and developed by Hangzhou Bopai Investment Management Co., Ltd. has a two-pronged approach from formula and process. In addition to “filling†static electricity in the production process through special processes, it can also use special sucking to drive special The friction of the material fibers creates new static electricity, and even the packaging of the storage mask can frictionally "charge" the mask. This special material property has even become a core secret that industry friends are eager to crack (if you need to know the basics of static electricity, please use your mother's shoes with time).
The Crusaders have large capacity, high adsorption, and low resistance.
When the anti-fog mask adopts "active adsorption" as the filtering method, it means that the fiber density can be greatly reduced, and the reduced fiber density invisibly increases the dust holding capacity of the mask. That is to say, even if the smog is severely worn for a long time, even if it filters enough small particles, the sucking resistance will not be greatly affected. Therefore, the mask recommended in this paper is to introduce the suction resistance of 50 Pa and 75 Pa as the main selling point of its products.
The crusaders use scarce materials, and they are in short supply.
Once the mask was introduced, the scarcity of the raw materials itself, the production capacity of the factory and the cash withdrawal from the various agents to the workshop were in stark contrast. It was no exaggeration to describe it with hot, explosive and explosive bursts, even Jingdong. Taobao's online store is hard to find the mask. Some agents have to retreat to the next level, this year has begun to book capacity in 2018.
49.8 Pa is the suction resistance of the cup type, and 35.9 Pa is the expiratory resistance.
The price of the Crusaders is close to the people, and the cost of use is only 1/3 of 3M.
If the capacity is not enough, this mask will become the biggest threat to 3M this year. Apart from the brand, no matter from the indicators, wearing comfort, and environmental protection, 3M will take a few streets. Even so, the manufacturer still sets the price very close to the people, the minimum price of the three-piece folding valveless mask is only 49 yuan, because 2 times the excess dust capacity of 3M or more, that is, 3 masks equivalent More than 6 3M, the actual cost of a single mask is less than 1/3 of 3M.
Amount of clothing: red for the cup type, black for the folding type, in addition to the folding type of sales of 15 pieces, the cup type has a valve, no valve, folding no valve are 25 pieces;
In the actual measurement, many users said that the design is not beautiful enough. In fact, Xiaobian’s heart is also like this drop~~O(∩_∩)O haha~.
However, such a powerful mask can block more than 95% of the smog, and there is almost no resistance. The value of the care of the parents will give us a chance to change, seriously change, and thoroughly change, but we have to wait until the spring. ~
