This media is electrostatically enhanced and available in efficiencies from F5 to Y It is mainly engineered for pleated filter or pocket filter designs after processing. Double charged technology is used to this meltblown filter media, which increase the charged particles on the fibers.
Emix PD Filter Media can be an ideal choice to achieve the lower resistance without losing the efficiency of the filter. The low initial resistance can also contribute to an overall strategy of reducing energy consumption. It is suitable for laminating to other materials for using in air conditioner, cabin air filters and HAVC. Electrostatic Filter Media is made of modified polypropylene fiber.The melt-blown nonwoven fabric is known as the "heart of the mask", disperses molten plastic through high-speed hot air, and spins the polymer melt through the spinneret of the ultra-fine nozzle, making it a high-performance polypropylene melt-blown filter material.
Fibers are extremely thinner than other materials. Without increasing the loading of uses, through electrostatic electret technology, the static electricity is absorbed in the melt-blown non-woven fiber, it can absorb viruses and bacteria that have penetrated through the surface layer, thereby improving the filtering performance of masks and other filtering products.
The outermost layer of the mask is spunbonded non-woven fabric, which is highly breathable and water-repellent, and the first is to prevent the contamination of droplets; the middle layer is a melt-blown non-woven fabric, which mainly filters the virus, bacteria, dust and droplets in the air. The layer is made of water needle non-woven fabric, which absorbs sweat and grease, and the soft fiber allows users to have an excellent wearing experience.Wss shoe store

The meltblown nonwoven, the core material of the mask, determines to a large extent whether the masks made are qualified. Good meltblown nonwoven masks are generally not too bad, meltblown nonwoven test reports generally do breathing resistance tests, filtration efficiency test, microbial test, and other three items. If you want to produce a mask, you should first test the meltblown nonwoven to see if it is qualified, so that the meltblown nonwoven does not fail, resulting in the production of the mask is not qualified then it will be a loss.
Most Penetrating Particle Size MPPS : In particulate matter filtration efficiency testing, particulate matter diameters that are too large or too small are easily filtered by the face mask, so there is a range of particulate matter diameters that are most difficult to filter, which we call the most penetrating particle size. Viral blocking is basically equivalent to particulate matter filtration efficiency.
The masks we use are generally 3 layers and above. Inner and outer materials, mostly polypropylene spunbond nonwoven materials, the particle filtration efficiency of which is limited.
The middle layer to play a particle filtering role with the electret polypropylene meltblown nonwoven materials, the material can use electrostatic adsorption of particles, thus greatly improving the filtration efficiency.Trafique coffee pt
The filtration of particulate matter by filtration materials mainly has the effect of gravity settlement, interception, inertial collision, diffusion, electrostatic adsorption, etc. Under the joint action of various filtration mechanisms, there is a minimum value of filtration efficiency for particulate matter with an aerodynamic particle size around 0.
It is easiest to capture small-scale particles, fine fibers, and particles with low velocity motion. Large particles, high density, and fast velocity have a good interception. The smaller the particle, the stronger the 1 and 4 deposition effect, and the larger the particle, the better the 2 and 3 effects, so not the smaller particle the harder it is to filter. Combining the synergy of the four filtration mechanisms, the most easily penetrated particle size is 0.
The meltblown nonwoven fabric has a finer fiber structure than spunbonded nonwoven fabric, and therefore has better trapping properties for tiny particles. The use of meltblown nonwoven fabric with good processing performance, excellent chemical resistance polypropylene as raw material, better filtration efficiency, insulation performance is excellent, in addition to high porosity, good breathability. The main test properties are as follows.
In addition, with reference to the relevant face mask standards, companies also have to conduct particle filtration efficiency test, bacterial filtration efficiency test, ventilatory resistance and pressure difference test, airflow resistance and breathing resistance test for meltblown nonwoven.
Common test items for each national mask standard are listed below.Medical masks generally use a multilayer structure, referred to as the SMS structure: a single layer of spunbond S on both sides and a single or multiple layers of meltblown layer M in the middle.
The best material for meltblown layers is melt. Spray cloth. The main material that brings the virus filtering effect to the mask is the middle M layer-meltblown non-woven fabric. Melt-blown cloth is made of a polypropylene material called high-melt-finger fiber. It is a kind of ultra-fine electrostatic fiber cloth, which can effectively use static electricity to absorb virus dust and droplets.
This is also an important reason why masks can filter viruses. If you don't know if your mask can be anti-virus, check if there is a meltblown cloth in the mask. In fact, these three layers are all non-woven fabrics, and the raw materials are polypropylene, but the manufacturing process is different. Among them, the diameter of the spunbond layer on the inside and outside is relatively thick, about 20 microns; the diameter of the meltblown layer in the middle is only 2 microns, and it is made of a polypropylene material called high melt index fiber.
It is fragile and cannot be washed with water or sprayed with alcohol. Even if it is wet and then dried, it will damage the fibers and cause loopholes.
The virus will pass through the loopholes and the mask will lose its protective ability. Therefore, if you want to recycle the mask, you can't steam it, bake it at high temperature, or spray it with alcohol. The best way is to hang it in a ventilated place. What is melt-blown cloth? If you don't know if your mask can be anti-virus, check if there is a meltblown cloth in the mask In fact, these three layers are all non-woven fabrics, and the raw materials are polypropylene, but the manufacturing process is different.China Medical Resources.
Electrostatic Melt Blown Fabric is melt blown fabric treated by electrical treatmen via high voltage and makes itself with eletrostatic.
The blind investment in the early stage caused some meltblown cloth manufacturers to suffer extremely heavy economic losses.
The editor of Sino-Singapore Huamei Modified Plastics has compiled the information and discussed with you what is meltblown electret treatment. Electret refers to a dielectric material with long-term storage of electric charges.
It has the advantages of high efficiency, low flow resistance, antibacterial, and energy saving. On the basis of ensuring the physical collision blocking effect of conventional filter materials, it adds electrostatic adsorption.
The electret treatment makes the filter material fibers charged, combined with the dense characteristics of the meltblown ultrafine fiber material, so a large number of electrodes are formed between the charged fibers.
The charged fibers can not only attract most of the charged particles in the environment like a magnet, but also Part of the uncharged particles can be polarized, and then some pollutants with a smaller particle size can be adsorbed, and even nano-sized substances such as viruses can be electrostatically adsorbed or blocked by charge repulsion. FDA also conducted some tests and the results show that the filtration efficiency of masks whose melt blown cloth withouth electrical treatment is less than 50 than masks with Electrostatic Melt Blown Fabric.
Experiments have proved that after adding electret masterbatch, the electret effect of meltblown cloth is greatly improved, and its surface charge density, filtration performance and antibacterial properties are significantly improved.
The main material of meltblown cloth is polypropylene, which is a kind of ultrafine electrostatic fiber cloth, which can capture dust. When droplets containing pneumonia virus come close to the meltblown non-woven fabric, they will be electrostatically adsorbed on the surface of the non-woven fabric and cannot penetrate.
This is how this material isolates germs, dust, particles, virus. After the dust is captured by the ultra-fine electrostatic fiber, it is very difficult to be removed due to washing, and washing with water will also destroy the electrostatic dust collection ability.
