Nwayo Mask - twal meltblown | JINHAOCHENG

Mask nwayo a nan  twal meltblown te fè nan polypropylène fib superfine ansanm ak distribisyon o aza, aparans la, lis, mou ak blan rafineman materyèl fib 0.5 a 1.0 mu m, distribisyon an o aza nan fib bay plis opòtinite pou lyezon tèmik ant fib la e konsa fè fonn-kònen materyèl filtraj gaz gen pi gwo zòn sifas espesifik, pi wo porositë (75%) oswa pi wo. Atravè efikasite nan vòltaj segondè filtraj Stationer, pwodwi a gen karakteristik sa yo nan rezistans ki ba, efikasite segondè, epi segondè kapasite pousyè tè .

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.

Kouch pwoteksyon an nan mitan mask la (kouch M pou kout) se polypropylène fonn-flite twal ki pa tise, ak devan yo ak pati dèyè yo nan mask la yo se kouch spunbonded (S kouch pou kout). pwoteksyon obligatwa, youn nan plis kouch ka mete nan kouch M. Si li se yon mask pwoteksyon nivo 1, sèvi ak yon kouch M. Pou yon respiratè nivo 3 tankou N95 a, kouch M-la ka mande pou twa kouch fonn-flite twal nonwoven oswa plis.Natirèlman, kouch yo plis nan kouch M, pèmeyabilite ki nan lè a vin pi mal nan mask la, pwodwi yo espesifik yo pral diferan.

Si nou chire louvri yon mask, nou pral wè twa kouch ki anwo yo, sètadi kouch igroskopik la, kouch filtre debaz la, ak kouch baryè dlo a.

Fonn twal espre, ki chita nan mitan kouch filtre mask la, ka filtre bakteri, anpeche gaye jèm yo .. Fonn twal espre, fonn twal espre sitou nan polipropilèn kòm prensipal matyè premyè, dyamèt fib ka rive jwenn 1 ~ 5 mikron. fib ultrafin ak estrikti kapilarite inik ogmante kantite a ak zòn sifas nan fib pou chak zòn inite, se konsa ke twal la fonn-jè gen bon filtraj, pwoteksyon, izolasyon ak pwopriyete absòpsyon lwil oliv.Li ka itilize nan lè, materyèl filtraj likid, materyèl izolasyon , materyèl absòbe, materyèl mask, materyèl izolasyon tèmik, materyèl lwil oliv-absòbe ak siye moso twal ak lòt jaden.

Entèsepsyon ak adsorption

Fonn twal kònen se yon kalite polypropylène ak endèks k ap fonn segondè, ki se te fè nan anpil fib kwa-kwa laminated nan yon direksyon o aza. Dyamèt fib yo varye ant 0.5 a 10 mikron, ak dyamèt fib yo se apeprè yon trantyèm nan yon cheve.

Kòm ka wè nan foto a, gen toujou anpil twou vid ki genyen nan mask la anba mikwoskòp la elèktron. Se konsa, kouman nou ka bloke viris la?

Entèsepsyon:

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.

Adsorption:

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.

Akòz kapasite inik nan adsorption Electrostatic, teknoloji a espre k ap fonn ka pwodwi fib chimik ak yon dyamèt yon sèl lòd nan grandè ki pi piti pase sa yo ki nan fib natirèl, ki se tou fezab nan jenerasyon an nan adsorption chimik. Polypropylène fonn-flite twal ki pa tise se san dout premye chwa pou materyèl mask pwoteksyon medikal
