COVID-19 Mhinduro: Vagadziri nevashambadzi vanopa masosi eCCIDID-19 zvekurapa ico-museve-default-kurudyi
Kamwe mask yekuvhiya yaingova tambo yejira yakasungirirwa kumeso kwachiremba kana mukoti, ikozvino yakagadzirwa nemucheka usina kurukwa wakagadzirwa nepolypropylene nemamwe mapurasitiki ekusefa nekudzivirira.Zvinoenderana nedanho redziviriro rinodiwa nevashandisi, vane akawanda akasiyana masitayipi nematanho.Kutsvaga rumwe ruzivo nezve masks ekuvhiya kuti asangane nekutenga kwako kwekurapa zvaunoda?Isu takagadzira gwara iri kuti ritsanangure zvimwe zvezvakakosha nezvemasks aya uye kuti anogadzirwa sei.Kana iwe uchifarira kudzidza zvakawanda nezve magadzirirwo ekufemesa, zvipfeko zvekudzivirira uye zvimwe zvekuzvidzivirira nazvo, unogona zvakare kushanyira yedu PPE yekugadzira ongororo.Iwe unogona zvakare kutarisa chinyorwa chedu pamusoro pemachira masiki uye masks ekuvhiya.
Masks ekuvhiya akagadzirirwa kuchengetedza imba yekuvhiya isina hutachiona uye kudzivirira mabhakitiriya mumhino nemumuromo weanopfeka kubva pakusvibisa murwere panguva yekuvhiya.Kunyangwe ivo vari kuramba vachizivikanwa pakati pevatengi panguva yekubuda senge coronavirus, masks ekuvhiya haana kugadzirwa kusefa mavhairasi madiki pane mabhakitiriya.Kuti uwane rumwe ruzivo nezve rudzi rwemask rwakachengeteka kune vashandi vekurapa vanobata nezvirwere zvakaita sekoronavirus, unogona kuverenga chinyorwa chedu pamusoro peCDC-inotenderwa vatengesi vepamusoro.
Zvinofanira kucherechedzwa kuti mishumo ichangoburwa kubva kuHealthline neCDC inoratidza kuti masiki ane mavharuvhu kana mavharuvhu anogona kuparadzira hutachiona.Masks achapa munhu akapfeka dziviriro yakafanana neyemasiki asina mhepo, asi vharuvhu haidzivise hutachiona kubuda, izvo zvinozobvumira vanhu vasingazive kuti vane hutachiona kuparadzira hutachiona kune vamwe.Izvo zvakakoshawo kuziva kuti masiki asina masks anogona zvakare kuparadzira hutachiona.
Masks ekuvhiya akakamurwa kuita mazinga mana zvinoenderana neASTM certification, zvichienderana nedanho redziviriro ravanopa kune anoripfeka:
Zvinofanira kucherechedzwa kuti masikisi ekuvhiya haana kufanana nemasikisi ekuvhiya.Masks anoshandiswa kuvhara splashes kana aerosols (sekunyorova kana kuhotsira), uye anonamirwa kumeso kumeso.Mafemero anoshandiswa kusefa zvinhu zvinofambiswa nemhepo, zvakaita semavhairasi uye mabhakitiriya, uye kugadzira chisimbiso chakatenderedza mhuno nemuromo.Kana murwere aine hutachiona hwehutachiona kana zvimedu, mhute kana magasi aripo, mushonga wekufema unofanirwa kushandiswa.
Masikisi ekuvhiya akasiyanawo nemasiki ekuvhiya.Masks ekuvhiya anoshandiswa munzvimbo dzakachena muzvipatara, kusanganisira nzvimbo dzinochengeterwa varwere zvakanyanya uye mawadhi ekusununguka, asi haana kubvumidzwa kushandiswa munzvimbo dzisina hutachiona semakamuri ekuvhiya.
Kubva muna Mbudzi 2020, CDC yakagadziridza gwara rayo rekushandiswa kwemasks kubvumidza zvipatara nedzimwe nzvimbo dzekurapa kuwedzera zviwanikwa panguva yekunyanya kudiwa.Hurongwa hwavo hunotevera nhevedzano yematanho ekuwedzera mamiriro ezvinhu ekukurumidzira kubva kumabasa akajairwa kuenda kumabasa enjodzi.Mamwe matanho ekukurumidzira anosanganisira:
Munguva pfupi yapfuura, ASTM yakagadzira seti yezviyero zvemasiki egiredhi evatengi, umo masiki ekirasi I anogona kusefa makumi maviri muzana ezvikamu zviri pamusoro pe 0.3 microns, uye kirasi II masiki anogona kusefa makumi mashanu muzana ezvikamu zviri pamusoro pe 0.3 microns.Nekudaro, izvi ndezvekushandiswa kwevatengi chete, kwete kushandiswa kwekurapa.Kubva panguva yekunyora, CDC haisati yavandudza nhungamiro yayo kugadzirisa nyaya yekuti masks aya (kana aripo) anogona kushandiswa nevashandi vekurapa pasina PPE chaiyo.
Masikisi ekuvhiya anogadzirwa nemachira asina kurukwa, ane mabhakitiriya ari nani kusefa uye kufema, uye asingatsvedze pane machira akarukwa.Zvinhu zvinonyanya kushandiswa kuzvigadzira ndeye polypropylene, iyo ine density ye20 kana 25 magiramu paskweya mita (gsm).Masks anogona zvakare kugadzirwa ne polystyrene, polycarbonate, polyethylene kana polyester.
Iyo 20 gsm mask zvinhu inogadzirwa uchishandisa spunbond maitiro, ayo anosanganisira kuburitsa purasitiki yakanyungudutswa pabhandi rekutakura.Izvo zvinyorwa zvinowedzerwa muwebhu, umo tambo dzinonamatira kune imwe neimwe sezvainotonhora.25 gsm jira rinogadzirwa neyakanyungudutswa yakavhuvhuta tekinoroji, inova maitiro akafanana ayo mapurasitiki anoburitswa kuburikidza nefa nemazana ediki madiki uye anofuridzirwa mumafibhi akanaka nemhepo inopisa, yakatonhodzwa zvakare uye yakaiswa pane inotakura bhandi 上胶。 Pa glue. .Iyo dhayamita yemafiber aya ishoma pane imwe micron.
Masks ekuvhiya anosanganisira akawanda-layer chimiro, kazhinji dhizaini rejira risiri rakarukwa rakavharwa pajira rejira.Nekuda kwehunhu hwawo hwekurasa, machira asina kurukwa akachipa uye akachena kugadzira uye anogadzirwa nemitsara mitatu kana ina.Aya masiki anoraswa anowanzo kugadzirwa maviri mafirita akaturikidzana, ayo anogona kunyatso kusefa mabhakitiriya uye zvimwe zvimedu zvakakura kupfuura 1 micron.Nekudaro, iyo filtration level yemask inoenderana nefiber, nzira yekugadzira, chimiro chefiber net uye muchinjiko-chikamu chimiro chefiber.Masks anogadzirwa pamutsetse wemuchina unounganidza machira asiri akarukwa pane spools, welds machira pamwe chete ne ultrasound, uye anodhinda mabhendi emhino, mhete uye zvimwe zvikamu pamasiki.
Mushure mekunge mask yekuvhiya yaitwa, inofanirwa kuyedzwa kuti ive nechokwadi chekuchengetedza kwayo mumamiriro akasiyana.Vanofanira kupasa bvunzo shanu:
Fekitari yembatya uye vamwe vagadziri vemishonga yemazuva ese vanogona kuve vagadziri vemasiki ekuvhiya, asi pane zvakawanda zvinonetsa zvekukunda.Iyi haisi nzira yehusiku humwe, nekuti chigadzirwa chinofanira kubvumidzwa nemasangano mazhinji nemasangano.Zvipingamupinyi zvinosanganisira:
Kunyangwe paine kushomeka kwezvinhu zvemasiki ekuvhiya nekuda kwedenda ririkuenderera mberi, yakavhurika sosi modhi uye mirairo yemasks akagadzirwa nezvimwe zvinhu zvakajairika akabuda paInternet.Kunyangwe izvi zviri zveDIYers, zvinogona zvakare kushandiswa senzvimbo yekutanga yemhando dzebhizinesi uye kugadzira.Isu takawana mienzaniso mitatu yemasikirwo mapatani uye takapa zvinongedzo kumapoka ekutenga paThomasnet.com kuti ikubatsire kutanga.
