Topeng topeng - kain leleh | JINHAOCHENG

Topeng inti  kain sing dilebur digawe saka serat polipropilena superfine bebarengan karo distribusi acak, tampilan, alus, alus lan putih bahan serat saka 0,5 nganti 1,0 mu m, distribusi serat acak kanggo nyedhiyakake luwih akeh ikatan termal ing antarane serat lan kanthi mangkono nggawe bahan filtrasi gas sing diunekake luwih akeh kanthi luas permukaan sing luwih gedhe, porositas sing luwih dhuwur (75%) utawa luwih dhuwur. Liwat efisiensi filtrasi stationer voltase dhuwur, produk kasebut duwe ciri resistensi rendah, efisiensi dhuwur lan kapasitas debu sing dhuwur .

Melt-blown non-woven fabric as a new type of high efficient filter material is the "heart" masks, compared with traditional filter material, air filtration and purification efficiency into the improvement of one hundred times, is now the most suitable for biological health protection materials (activated carbon and similar material can be used for protective chemicals, against bacteria and viruses without filtration purification function).Its birth unexpectedly overnight the medical profession USES a hundred years gauze mask completely eliminated.Medical protection is generally divided into three levels according to the level of protection requirements.The light-blue "surgical masks" that we wear most often can be used for primary protection, primarily against the harmful transmission of droplets containing pathogens in daily life and production.The key measure to improve the protective ability is to add a filter layer made of melt-sprayed non-woven cloth in the middle of the mask.

Lapisan protèktif ing tengah topeng (lapisan M cekak) polipropilena kain sing ora dirajut, lan sisih ngarep lan mburi topeng iku lapisan spunbonded (lapisan S cekak). Gumantung saka level pangayoman sing dibutuhake, siji nganti luwih lapisan bisa dilebokake ing lapisan M. Yen topeng proteksi level 1, gunakake lapisan M. Kanggo respirator level 3 kaya N95, lapisan M bisa uga mbutuhake telung lapisan penyemprotan leleh kain ora tenunan utawa luwih. Mesthi wae, lapisan lapisan M sing luwih akeh, permeabilitas topeng udhara sing luwih elek, produk tartamtu bakal beda.

Yen mbukak topeng, kita bakal weruh telung lapisan ing ndhuwur, yaiku lapisan hygroscopic, lapisan filter inti, lan lapisan penghalang banyu.

Kain semprotan lebur, sing ana ing tengah lapisan filter topeng, bisa nyaring bakteri, nyegah panyebaran kuman. Kain semprotan lembut, kain semprotan leleh utamane menyang polipropilena minangka bahan baku utama, diameter serat bisa nganti 1 ~ 5 mikron. Iki serat ultrafine kanthi struktur kapiler unik nambah jumlah lan jembarane serat saben area, saéngga kain jet leleh nduweni penyaringan, tameng, insulasi lan penyerapan minyak sing apik. Bisa digunakake ing udara, bahan filtrasi cair, bahan isolasi , bahan nyerep, bahan topeng, bahan isolasi termal, bahan nyerep minyak lan kain usap lan lapangan liyane.

Interception lan adsorpsi

Kain lebur sing diunekake minangka jinis polipropilena kanthi indeks leleh sing dhuwur, sing digawe saka akeh serat salib salib sing dilaminasi kanthi arah acak. Dhiameter serat kasebut antara 0,5 nganti 10 mikron, lan diameter serat kasebut udakara telung puluh telung rambut.

Kaya sing bisa dideleng saka gambar kasebut, isih ana akeh celah ing topeng ing sangisore mikroskop elektron. Dadi, kepiye cara bisa mblokir virus kasebut?

Topengnglindhungi virus kanthi nindakake rong prekara: njebak lan njebak

Interception:

The filter material relies on textile or non-woven processes to achieve the density of the fibers in the space and form a certain network of pores, thus forming a "blocking" effect on the flowing air. The larger particles in the air are either "intercepted" by the collision with the fibers or by the fiber mesh blocking on the side of the filter material.For non-biological particles in the air (such as dust, PM2.5, etc.), the purification efficiency of masks mainly depends on the single interception ability of filter materials.

Adsorpsi:

For biological protective masks, due to the very small physical size of pathogens such as viruses, it is difficult to purify most of the harmful substances by interception of mask fiber gaps. Therefore, electrostatic adsorption has become an indispensable key feature of mask protection function.Traditional natural fibers are very weak in generating and carrying static electricity, so gauze masks have little adsorption effect.And the non-polar polymer melt jet fiber is an excellent material for electrostatic generation and retention (this point, you can compare the feeling of wearing pure cotton clothing and chemical fiber clothing), making it "inherently" has excellent adsorption performance.Researchers have done a lot of work on how to generate and maintain the electrostatic efficiency of filter materials. In mask production, mechanical or electronic means are used to enrich the electrostatic charge into molten spray materials.

Amarga kemampuan adsorpsi elektrostatik sing unik, teknologi semprotan lebur bisa ngasilake serat kimia kanthi diameter siji urutan gedhene luwih cilik tinimbang serat alami, sing uga kondensif kanggo generasi adsorpsi kimia. temtu dadi pilihan pertama kanggo bahan topeng proteksi medis
