Me yasa abin rufe fuska ke hana yaduwar kwayar cutar?

Wane irin abu ne?

Yawancin lokaci muna cewa abin rufe fuska an yi shi da yadudduka marasa saka.Yadudduka waɗanda ba saƙa ba su ne yadudduka ba, sabanin yadudduka da aka saka, waɗanda aka yi da filaye masu daidaitawa ko bazuwar.
Lokacin da yazo ga masks, albarkatun kasa shine polypropylene (PP).Mashin da ake zubarwa gabaɗaya polypropylene masu yawa ne.Sunan Ingilishi: Polypropylene, PP a takaice, mara launi ne, wari, mara guba, abu mai ƙarfi mai jujjuyawa, wanda shine fili na polymer wanda aka kafa ta hanyar polymerization na propylene.Ana amfani da polypropylene sosai wajen samar da samfuran fiber kamar su tufafi da barguna, kayan aikin likitanci, motoci, kekuna, kayayyakin gyara, bututun sufuri da kwantenan sinadarai, da kuma cikin kwalin abinci da magunguna.
Za'a iya amfani da masana'anta da ba a saka ba ta hanyar kayan musamman na polypropylene wanda ba a saka ba za a iya amfani da shi don zubar da kayan aiki, zanen gado, masks, murfi, gammaye na sha ruwa da kuma sauran magunguna da kayan kiwon lafiya.

Masks ɗin da aka san suna da tasirin kariya akan novel coronavirus galibi sun haɗa da abin rufe fuska na kariya da abin rufe fuska na N95.Babban kayan tacewa na waɗannan masks guda biyu yana da kyau sosai, electrostatic tace rufi - narke-busa masana'anta mara saƙa.Narke busa da ba saƙa masana'anta aka yafi yi da polypropylene, shi ne wani irin ultrafine electrostatic fiber zane, iya kama ƙura.
A droplets dauke da kwayar cutar huhu a kusa da narke-busa wanda ba saƙa zane zai zama electrostatic adsorption a saman wanda ba saka tufafi, ba zai iya wucewa ta, wannan shi ne ka'idar wannan. kwayoyin ware kwayoyin cuta.Bayan an kama ƙurar ta ultrafine electrostatic fiber, yana da matukar wahala a rabu da shi ta hanyar tsaftacewa, kuma wankewa zai lalata ikon tattara ƙurar electrostatic, don haka ana iya amfani da wannan abin rufe fuska sau ɗaya kawai.

Mashin kariya da za a iya zubarwa gabaɗaya ana yin su ne da yadudduka uku na masana'anta mara saƙa.Kayan yana spunbonded ba saƙa masana'anta + narke-busa da ba saƙa masana'anta + spunbonded mara saƙa masana'anta.
Ba a kayyade yadudduka da yawa na abin rufe fuska ba a cikin ma'aunin GB/T 32610 na ƙasa don abin rufe fuska.Don abin rufe fuska na likita, yakamata a sami aƙalla yadudduka 3, wanda ake kira SMS (2 layers na S da 1 Layer na M).
Mafi girman adadin yadudduka a China a halin yanzu shine 5 layers, wanda ake kira SMMMS (2 layers na S da 3 layers na M).Anan S yana wakiltar Spunbond Layer (Spunbond), diamita na fiber ɗin sa yana da ɗan kauri, game da 20 microns (μm), babban aikin 2 yadudduka na Spunbond shine don tallafawa duk tsarin masana'anta wanda ba a saka ba, kuma baya da tasiri sosai akan shinge.Abu mafi mahimmanci a cikin mask shi ne katangar shinge ko Meltblown Layer M (Meltblown).
Diamita na fiber na Layer Meltblown yana da ɗan kyau, kusan microns 2 (μm), wanda ke taka muhimmiyar rawa wajen hana ƙwayoyin cuta da jini shiga. cikin sa.Idan S spunded yadudduka sun yi yawa, abin rufe fuska yana da wahala, kuma fesa Layer M da yawa, numfashi yana da wahala, don haka daga sauƙi na abin rufe fuska zuwa kimanta tasirin abin rufe fuska, ƙarin numfashi. wuya, da tarewa sakamako ne mafi alhẽri, amma, idan M Layer a cikin fim, shi ne m ba numfashi da yardar kaina, cutar da aka yanke, amma mutane ba za su iya numfashi.N95 shine ainihin abin rufe fuska mai Layer 5 wanda aka yi daga polypropylene wanda ba a saka SMMMS wanda ke tace har zuwa kashi 95% na barbashi masu kyau.

Sabili da haka, mun gano cewa abin rufe fuska wanda zai iya ware kwayar cutar dole ne a yi shi da takamaiman kayan aiki, kuma ba duk kayan da suka dace da abin rufe fuska ba.
Kamar yadda na ƙarshe, mun ORANTA da gaske fatan kowa zai iya kiyaye kanku da lafiya.
