[Integrated] 3M China's status is difficult to guarantee? Crusader fog mask breaks through the problem of flood prevention and suction resistance

Thicker and thicker haze, masks also need to be upgraded

Experts predict that this year's haze season will come earlier and worse than in previous years. In fact, this year's haze has arrived since August, two months earlier than in previous years. How to choose an anti-fog mask, for the average user, the brand seems to be the only cognition. However, branding sometimes means reliance on the old to sell and not to make progress.

Today, we took a detailed description of the anti-fog and smog masks that were dumped on a few streets in 3M. I hope that everyone can prevent haze more easily this year, and it is not too heart-stopping.

The higher the filtration, the greater the resistance, difficulty in sucking into technical difficulties

The basic requirement for anti-fog and haze is to filter PM2.5 to more than 90%, but the higher the filtration efficiency is, the greater the suction resistance will be. The experts in the industry recognize the current production technology and materials, even if the reduction of 10% of the suction Resistance is a technical difficulty that is difficult to achieve. This point has not even solved 3M (maybe 3M's manufacturers think that their brand advantage is enough to eat, and perhaps people are big companies, dismissive for small breakthroughs) .

We conducted the most intuitive video test on the most important filtering efficiency of anti-fog and smog masks. The test source of pollution was cigarette smoke (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 full dark room.

The conclusion of the test is that there should be no major problems with visually filtering 90% of cigarette smoke because there is no corresponding test equipment in the industry.

Crusader electrostatic adsorption, easy breathing

First of all, we use a picture to understand the filtering principle of the general anti-fog mask on the market.

From the above figure, we can see that the inertial collision, cohesion interception, and adsorption effects must achieve “passive filtration” with fiber density. If the filtration efficiency is 100% dependent on the fiber density, the suction resistance will be infinite, just like A piece of glass can't suck at all.

Then, the only way to achieve filtration without relying on fiber density is to use active electrostatic adsorption. 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 attenuate when it meets water or in a certain period of time, infinitely close to zero. In other words, when static electricity is completely attenuated and there is no "passive filtering" of the material, then the mask will also be empty.

Crusader friction charging, perfect storage

Obviously, the capacitor can hold more charge due to the particularity of the material. Therefore, the core filter of the mask needs to be infinitely close to the capacitive material in order to achieve the purpose of injecting more static electricity. The particles in the air are all charged. The longer the use will neutralize the mask charges and reduce the static electricity, and the static electricity itself will be continuously attenuated by various factors.

Solution: The core filter material invested and developed by Hangzhou Bopa Investment Management Co., Ltd. has a two-pronged approach of formulating and processing materials. In addition to using special processes to “fill” the static electricity in the production process, it can also use its own suction to drive special The friction of the material fibers creates new static electricity, and even the masks that hold the masks can be used to frictionally "charge" the mask. This particular material characteristic has even become the core secret that the industry friend eagerly seeks to crack. (If you need to understand the basic knowledge of static electricity, there is time for children's shoes to use Duan Niang.)

Crusader capacity, high adsorption, low resistance, outstanding core advantages

When the anti-fog mask is “actively adsorbed” as the filtering method, it means that the fiber density can be greatly reduced, and the reduced fiber density virtually increases the dust holding capacity of the mask. In other words, even if it is worn for a long time when the haze is very serious, the suction resistance will not be greatly influenced even if enough small particles are filtered. Therefore, the mask recommended in this article is to use the inhalation resistance of 50 Pa and 75 Pa as the main selling point of its products.

The Crusaders use scarce materials, which are in short supply

After the introduction of the mask, the scarcity of raw materials, the production capacity of the factory and the contrast between the cash withdrawals from various agents and the arrival of the goods on the shop are in stark contrast. It is not an exaggeration to describe explosives, explosives, and explosions. Even Jingdong Taobao's online shop is hard to find the mask. Some dealers have no choice but to withdraw their attention. This year, they have begun booking 2018 capacity.

49.8 Pa for cup-type inspiratory resistance, 35.9 Pa for exhalation resistance

Crusader prices are close to the people, and the cost of use is only 1/3 of 3M.

If not, the mask will become the biggest threat for 3M this year. Apart from the brand, 3M will be thrown a few streets in terms of indicators, wearing comfort and environmental protection. In spite of this, the manufacturers still set the price very close to the people, the minimum price of the three-fold folding valveless mask is only 49 yuan, because 2 times more than 3M large dust-capacity, that is to say the three mask equivalent More than 6 of 3M, the actual cost of a single mask is less than 1/3 of 3M.

Sales equipment: red cup type, black folding type, in addition to the folding type of 15 units, the cup type valve, valveless, folded without valve are 25 pack;

In the actual measurement, many users said that the design is not beautiful enough. In fact, Xiao Bian's heart is so dripping ~ ~ O (∩ _ ∩) O ha ha ~.

However, such powerful masks can block more than 95% of smog. There is almost no resistance. The value that parents care about will give us an opportunity to change, seriously reform, and radically change, but we have to wait until spring. ~
