Kedu ihe kpatara ihe mkpuchi na-egbochi mgbasa nke nje?

Kedu ụdị ihe ọ bụ?

Anyị na-ekwukarị na a na-eji ihe mkpuchi na-abụghị akwa akwa.Uwe na-abụghị nke a na-akpa bụ akwa na-abụghị nke a kpara akpa, na-emegide ihe ndị a kpara akpa, nke a na-eji eriri agbado ma ọ bụ na-enweghị usoro.
A bịa n'ihe mkpuchi, akụrụngwa akụrụngwa bụ Polypropylene (PP).Ihe mkpuchi ndị a na-atụfu n'efu na-abụkarị polypropylene multilayered.Aha Bekee: Polypropylene, PP maka mkpụmkpụ, enweghị agba, ihe siri ike nke na-enweghị isi, nke na-adịghị egbu egbu, translucent, nke bụ ngwakọta polymer nke a na-emepụta site na polymerization nke propylene.A na-eji polypropylene eme ihe n'ọtụtụ ebe na mmepụta nke ngwaahịa fiber dị ka uwe na blanketị, ngwa ọgwụ, ụgbọ ala, igwe kwụ otu ebe, akụrụngwa akụrụngwa, ọkpọkọ ụgbọ njem na akpa kemịkalụ, yana nkwakọ ngwaahịa nri na ọgwụ.
Enwere ike iji akwa na-abụghị nke a na-emepụta site na ihe pụrụ iche nke polypropylene ákwà na-abụghị nke a na-emepụta maka uwe arụ ọrụ, akwa akwa, ihe mkpuchi, mkpuchi, ihe mkpuchi mmiri mmiri na ihe mkpuchi. ọgwụ na ahụike ndị ọzọ.

Ihe mkpuchi a maara na ọ nwere mmetụta nchebe na coronavirus akwụkwọ akụkọ gụnyere gụnyere ihe mkpuchi nchekwa na ihe mkpuchi N95.Isi ihe nzacha maka ihe mkpuchi abụọ a dị ezigbo mma, ihe nzacha electrostatic - akwa agbaze agbaze na-abụghị akwa.Agbazekwa fụọ na-abụghị kpara akwa bụ tumadi mere nke polypropylene, bụ ụdị ultrafine electrostatic eriri ákwà, ike weghara ájá.
Ndị ụmụ irighiri mmiri nwere nje oyi baa n'akụkụ akwa gbazere agbaze na-abụghị nke a kpara akpa ga-abụ adsorption electrostatic n'elu akwa na-abụghị akwa, enweghị ike ịgafe, nke a bụ ụkpụrụ nke a. bacteria kewapụrụ ihe onwunwe.Mgbe ultrafine electrostatic eriri weghaara uzuzu, ọ na-esiri ike ikewapụ ya site na nhicha, na ịsacha ga-ebibi ikike nchịkọta uzuzu electrostatic, yabụ enwere ike iji nkpuchi a naanị otu ugboro.

A na-ejikarị akwa akwa akwa atọ eme ihe mkpuchi nchebe a na-atụfukarị.Ihe a na-eme bụ akwa na-abụghị nke a kpara akpa + agbaze agbaze akwa akwa + akwa na-enweghị akwa.
Edepụtaghị ọtụtụ akwa mkpuchi n'ụkpụrụ mba GB/T 32610 maka ihe mkpuchi.Maka ihe mkpuchi ahụike, ekwesịrị inwe opekata mpe 3, nke a na-akpọ SMS (2 layers of S na 1 layer of M).
Ọnụ ọgụgụ kachasị elu nke ọkwa dị na China ugbu a bụ 5 layers, nke a na-akpọ SMMMS (2 layers of S na 3 layers of M).N'ebe a, S na-anọchi anya oyi akwa Spunbond (Spunbond), dayameta eriri ya dị oke oke, ihe dị ka 20 microns (μm), ọrụ bụ isi nke 2 layers nke Spunbond bụ ịkwado usoro akwa akwa na-abụghị nke a kpara akpa, ọ dịghịkwa enwe mmetụta dị ukwuu na mgbochi ahụ.Ihe kachasị mkpa n'ime nkpuchi bụ ihe mgbochi oyi akwa ma ọ bụ Meltblown oyi akwa M (Meltblown).
Dayameta fiber nke oyi akwa Meltblown dị ezigbo mma, ihe dị ka microns 2 (μm), nke na-arụ ọrụ dị mkpa n'igbochi nje na ọbara ịbanye. n'ime ya.Ọ bụrụ na S spun-boded layers karịrị akarị, ihe nkpuchi siri ike, na ịgbasa oyi akwa M nke ukwuu, iku ume siri ike, yabụ site na ịdị mfe nke mkpuchi iku ume ruo na ntule mmetụta nke mkpuchi iche, na-eku ume karịa. siri ike, na-egbochi mmetụta ka mma, ma, ma ọ bụrụ na M oyi akwa n'ime film, bụ ihu ọma adịghị eku ume efu, nje na-ebipụ, ma ndị mmadụ enweghị ike iku ume.N95 bụ n'ezie ihe mkpuchi 5-layer mere site na polypropylene nonwoven SMMMS nke na-enyocha ihe ruru 95% nke ezigbo ahụ.

Ya mere, anyị chọpụtara na ihe mkpuchi nke nwere ike kewapụ nje ahụ ga-abụrịrị ihe a kapịrị ọnụ, ọ bụghịkwa ihe niile dị mma maka mkpuchi.
N'ikpeazụ, anyị ji ezi obi na-atụ anya onye ọ bụla nwere ike ichekwa onwe gị nchekwa na ahụike.
