Inovhara musimboti wejira rakanyungudukazvinhu zvekusefa zvakagadzirwa nefiber yepolypropylene superfine pamwe chete nekugoverwa kwakasarudzika, chitarisiko, kupfava, kupfava uye kuchena kwezvinhu zvefiber kupenya kwe0.5 kusvika 1.0 mu m, kugoverwa kwakasarudzika kwefiber kupa mikana yakawanda yekubatana kwekupisa pakati pefiber uye nokudaro zvinoita kuti zvinhu zvekusefa gasi zvakanyunguduka zvive nenzvimbo yakakura, porosity yakakwira (75%) kana kupfuura. Kuburikidza nekushanda kwe high voltage stationer filtration efficiency, chigadzirwa chine hunhu hwekusagadzikana kwakaderera, kushanda kwakakwirira uye kugona guruva kwakakwira.
Chidimbu chemasiki
Jira risina kurukwa rakanyungudutswa semhando itsva yezvinhu zvinosefa zvinoshanda zvakanyanya ndiro masks e "moyo", zvichienzaniswa nezvinhu zvechinyakare zvekusefa, kusefa kwemhepo uye kuchenesa kusvika pakuvandudzika kwezana, ikozvino ndiyo yakakodzera zvakanyanya pazvinhu zvekuchengetedza hutano hwebhayoloji (activated carbon nezvimwe zvinhu zvakafanana zvinogona kushandiswa pamakemikari ekudzivirira, kubva kumabhakitiriya nemavhairasi pasina basa rekuchenesa kusefa). Kuzvarwa kwayo kusingatarisirwi husiku hwese, nyanzvi yezvekurapa INOSHANDISA mask ye gauze yemakore zana yakabviswa zvachose. Dziviriro yekurapa inowanzo kamurwa kuita mazinga matatu zvichienderana nemazinga ekudzivirira. "Masks ekuvhiya" ebhuruu-rechiedza atinowanzo pfeka anogona kushandiswa pakudzivirira kwekutanga, kunyanya kubva pakupararira kunokuvadza kwemadonhwe ane utachiona muhupenyu hwezuva nezuva nekugadzirwa. Chinhu chakakosha chekuvandudza kugona kwekudzivirira ndechekuwedzera jira rekusefa rakagadzirwa nejira risina kurukwa rakanyungudutswa rakapfapfaidzwa pakati pemasiki.
Rutivi rwekudzivirira ruri pakati pemasiki (rutivi rweM muchidimbu) ijira risina kusukwa rakanyungudutswa nepolypropylene, uye mativi ekumberi nekumashure emasiki akaputirwa nebonded layers (rutivi rweS muchidimbu). Zvichienderana nedanho rekudzivirira rinodiwa, rutivi rumwe kusvika kune akawanda anogona kuiswa murutivi rweM. Kana iri mask yekudzivirira yedanho rekutanga, shandisa M layer. Kune respirator yedanho rechitatu seN95, M-layer ingada jira risina kusukwa rakanyungudutswa nepanho kana kupfuura. Ehe, kana jira reM rakawanda, kupenya kwemhepo kwakanyanya kwemasiki, zvigadzirwa zvacho zvichasiyana.
Kana tikabvarura mask, tichaona zvikamu zvitatu zviri pamusoro, zvinoti hygroscopic layer, core filter layer, uye water barrier layer.
Jira rekupfapfaidza rakanyunguduka, riri pakati pechikamu che masiki, rinogona kusefa mabhakitiriya, kudzivirira kupararira kwehutachiona. Jira rekupfapfaidza rakanyunguduka, jira rekupfapfaidza rakanyunguduka rinonyanya ku polypropylene sechinhu chikuru chisina kugadzirwa, dhayamita yefiber inogona kusvika 1 ~ 5 micron. Aya mafiber akapfava ane chimiro chakasiyana che capillarity anowedzera huwandu nenzvimbo yepamusoro yefibers pachikamu chimwe nechimwe, kuitira kuti jira rekunyunguduka rive nehunyanzvi hwakanaka hwekusefa, kudzivirira, kudzivirira uye kunyudza mafuta. Rinogona kushandiswa mumhepo, muzvinhu zvekusefa mvura, muzvinhu zvekuparadzanisa, muzvinhu zvinonyudza, muzvinhu zvinonyudza masiki, muzvinhu zvinonyudza thermal, muzvinhu zvinonyudza mafuta uye mujira rekupukuta nezvimwe.
Kuvharirwa uye kunyudzwa
Jira rakanyunguduka rakanyunguduka imhando yepolypropylene ine indekisi yekunyunguduka yakakwira, iyo inogadzirwa nemafiber akawanda akachinjika akasungirirwa nenzira isina kurongeka. Dhayamita yemafiber iri pakati pe 0.5 kusvika 10 microns, uye dhayamita yemafiber iri panosvika chikamu chimwe muzvitatu chebvudzi.
Sezvatinoona pamufananidzo, kuchine mipata yakawanda mumasiki pasi pemaikorosikopu yemagetsi. Saka tingadzivirira sei hutachiona?
Masikidziviriro kubva kumavhairasi nekuita zvinhu zviviri: kuteya uye kuteya
Kuvharirwa:
Sefa yacho inoshandisa nzira dzemachira kana dzisina kurukwa kuti iwane huwandu hwemafiber ari munzvimbo yacho uye igadzire network yemapores, zvichiita kuti mhepo ifambe zvakanaka. Mafiber makuru ari mumhepo anogona "kubatwa" nekusangana nemafiber kana kuti nefiber mesh blocking iri padivi pesefa. Kune mafiber asiri ehupenyu ari mumhepo (senge guruva, PM2.5, nezvimwewo), kushanda zvakanaka kwemasiki kunoenderana nekugona kwesefa kunobata mafiber kamwe chete.
Kunyudzwa kwemvura:
Kune masks ekudzivirira echisikigo, nekuda kwehukuru hudiki hwehutachiona hwakadai semavhairasi, zvakaoma kuchenesa zvinhu zvakawanda zvinokuvadza nekubata mavanga e fiber yemasiki. Nokudaro, electrostatic adsorption yave chinhu chakakosha chekudzivirira mask. Fiber dzechisikigo hadzina simba mukugadzira nekutakura magetsi asingachinji, saka masks dzegauze hadzina simba re adsorption. Uye non-polar polymer melt jet fiber chinhu chakanaka chekugadzira nekuchengetedza magetsi asingachinji (pano unogona kuenzanisa kunzwa kwekupfeka zvipfeko zvedonje zvakachena uye zvipfeko zve fiber zvemakemikari), zvichiita kuti "zvakare" zvive ne adsorption yakanaka. Vaongorori vakaita basa rakawanda pakugadzira nekuchengetedza kushanda kwe electrostatic kwezvinhu zvekusefa. Mukugadzira masks, nzira dzemakanika kana dzemagetsi dzinoshandiswa kuwedzera electrostatic charge kuita zvinhu zvakanyungudutswa zvekupfapfaidza.
Nekuda kwekugona kwakasiyana kwe electrostatic adsorption, tekinoroji yekupfapfaidza inonyungudutsa inogona kugadzira makemikari ane dhayamita imwe chete pasi pemafiber echisikigo, izvo zvinobatsirawo pakugadzira makemikari adsorption. Mucheka usina kurukwa wePolypropylene melt-sprayed non-woven pasina mubvunzo ndiyo sarudzo yekutanga yezvinhu zvekudzivirira zvekurapa.
