Factory direct selling 95 melt blown non-woven fabric kn95 filter material melt blown fabric Grade 99

  Fujian Dongqian Medical Technology Development Co
, Ltd
, We mainly develop and produce melt blown fabrics, non-woven fabrics, etc Bfe90 95 99 pfe90 95 99 three grades of standard filtration efficiency meets the standard sterilization meets the standard melt blown cloth PFE bacterial filtration BFE particle filtration uses Sinopec raw material electret masterbatch production electret machinery is first evolved and imported, which has reached the international level The mask produced by bfe95-99 meltblown cloth has high filtration efficiency for virus size particles High grade masks made of 95-99 melt blown cloth are more effective in sterilization
Modern masks are no longer & ldquo; Sieve & rdquo; The principle of
It's & ldquo; Active adsorption & rdquo;
Mainstream materials are called & ldquo; Electret melt blown electrostatic adsorption material;, This material has an electric field inside
It can remove particles passing nearby & ldquo; Suction & rdquo; Stay
Achieve effective sterilization and bacteria removal efficiency This adsorption characteristic is close to the barrier ability of large particles and small particles
Even when the particles become very small, the filtration capacity will be improved , & ldquo; Filter viruses & rdquo; From a practical perspective
Many people will take it for granted that the virus is so small that it is useless if the mask has insufficient barrier ability to 0
1 micron particles
This assumption is based on & ldquo; A virus can infect people & rdquo; On the basis of imagination, however, this is not the case in reality
In the face of human's strong immune system, the virus also needs & ldquo; Corps operations & ldquo; Just go, thousands of viruses attack a little at the same time, so as to tear a hole in the human immune system
Therefore, the larger the virus particle, the more virus it carries, and the more dangerous it is
However, the larger the particles, the easier they are to be blocked by masks, even very primary masks
The use of high standard masks can effectively block bacterial infection General daily protection, surgical disposable mask, bfe99 mask, PM2 5 masks are enough, so for the daily protection of general life, medical surgical masks are effective enough
The mask of BFE 99 is also effective enough
Only when you need to go to the hospital, share a room with patients, spend time together day and night, or have to be in a closed space with many patients, it is necessary to change the mask of N95 or vfe99
PM2
5 refers to 2
5 & mu in general; Particles within m also include virus scale particles
Not just 2
5 & mu; M particulate matter
So if a mask, on PM2 The filtration capacity of 5 can reach more than 95%, which is enough for daily protection
In addition, the thicker the mask or the more layers, the higher the efficiency
The actual measurement shows that the effect of simply superimposing the layers of mask on the filtration efficiency is limited
The stacking thickness of electret material is large, which has more impact on the dust capacity, that is, the total service life of the mask, rather than the filtration efficiency
However, after more layers, respiratory resistance will increase
Therefore, we don't need to pursue VFe mask in daily protection, because the latter usually has large respiratory resistance and low wearing comfort
It is especially unfriendly to the elderly and children with poor cardiopulmonary function In view of the above factors, our company uses the advanced physique of high-tech meltblown machine technology and electret technology to produce bfe-pfe meltblown electret isolation technology with the highest sterilization rate
Mass production and mass supply
Hope that the majority of businesses purchase, thank you ,
