Kutheni iimaski zithintela ukusasazeka kwale ntsholongwane?

Luhlobo olunjani lwemathiriyeli?

Sidla ngokuthi iimaski zenziwe ngamalaphu angalukwanga.Iingubo ezingabonakaliyo ziyimpahla engabonakaliyo, ngokuchasene neempahla ezilukiweyo, ezenziwe nge-oriented or random fibers.
Xa kuziwa kwiimaski, izinto eziluhlaza yiPolypropylene (PP).Iimaski ezilahlwayo zidla ngokuba ziiPolypropylene ezininzi.Igama lesiNgesi: Polypropylene, PP ngokufutshane, ayinambala, into eqinileyo engenavumba, engeyotyhefu, eguquguqukayo, eyikhompawundi yepolymer eyenziwe yipolymerization yepropylene.I-Polypropylene isetyenziswa ngokubanzi kwimveliso yeemveliso zefiber ezifana nempahla kunye neengubo, izixhobo zonyango, iimoto, iibhayisekile, iintsimbi, imibhobho yezothutho kunye nezikhongozeli zeekhemikhali, kunye nokupakishwa kokutya namayeza.
Ilaphu elingalukwanga eliveliswe yilaphu elikhethekileyo le-polypropylene elingalukwanga lingasetyenziselwa iimpahla zokusebenza ezilahlwayo, amashiti, iimaski, izigqubuthelo, iipads zokufunxa ulwelo kunye ezinye izixhobo zonyango kunye nempilo.

Iimaski ezaziwayo ukuba zineziphumo ezikhuselayo kwi-coronavirus yenoveli ikakhulu zibandakanya iimaski ezikhuselayo kunye neemaski ezi-N95.Esona sixhobo sokucoca iimaski zimbini zilungile kakhulu, i-electrostatic filter lining - ilaphu elingalukwanga elinyibilikayo elivuthelweyo.Ilaphu elingalukwanga elivuthelweyo lenziwe ngepolypropylene, luhlobo lwelaphu le-ultrafine electrostatic fibre, linokuthimba uthuli.
Amathontsi equlethe intsholongwane yenyumoniya kufutshane nelaphu elingalukiweyo elinyibilikayo liya kuba yi-electrostatic adsorption kumphezulu welaphu elingaphothiweyo, alinakudlula kulo, ngumgaqo woku. iibhaktheriya zokuzihlukanisa izinto.Emva kokuba uthuli lubanjwe yi-ultrafine electrostatic fiber, kunzima kakhulu ukwahlula ngokucoca, kwaye ukuhlamba kuya kutshabalalisa amandla okuqokelela uthuli lwe-electrostatic, ke le maski ingasetyenziswa kube kanye kuphela.

Iimaski zokhuselo ezilahlwayo ziqhele ukwenziwa ngokwemigangatho emithathu yelaphu elingalukwanga.Imathiriyeli lilaphu eliphothiweyo elingalukwanga + ilaphu elingalukwanga elinyibilikayo + eliphothiweyo elingalukwanga.
Iimaleko ezininzi zeemaski azichazwanga kumgangatho wesizwe we-GB/T 32610 weemaski.Kwiimaski zonyango, kufuneka kubekho ubuncinane i-3 layers, ebizwa ngokuba yi-SMS (i-2 layers ye-S kunye ne-1 ye-M).
Elona nani liphezulu leeleya e-China okwangoku zi-5 iileya, ezibizwa ngokuba yi-SMMMS (ii-2 iileya ze-S kunye ne-3 ze-M).Apha i-S imele umaleko weSpunbond (iSpunbond), idiameter yayo yefiber ityebile. malunga nama-microns angama-20 (μm), indima ephambili ye-2 layers ye-S Spunbond kukuxhasa yonke into engalukiweyo yelaphu isakhiwo, kwaye ayinayo impembelelo enkulu kumqobo.Eyona nto ibalulekileyo ngaphakathi kwemaski ngumaleko womqobo okanye umaleko we-Meltblown M (Meltblown).
Idayamitha yefiber yeMeltblown layer ilungile, malunga ne-2 microns (μm), edlala indima ebalulekileyo ekuthinteleni ibhaktheriya kunye negazi ukuba lingangeni. kuyo.Ukuba i-S spun-bonded layers ingaphezulu kakhulu, imaski inzima, kwaye umaleko wokutshiza M kakhulu, ukuphefumla kunzima, ke ukusuka ekukhululekeni kokuphefumla imaski ukuya kuvavanyo lwesiphumo seemaski zodwa, ukuphefumla ngakumbi. nzima, isiphumo evalela ngcono, kodwa, ukuba umaleko M kwifilimu, ngokusisiseko musa ukuphefumla ngokukhululekileyo, intsholongwane inqunyulwe, kodwa abantu abakwazi ukuphefumla.I-N95 eneneni imaski ene-5-layer eyenziwe kwi-polypropylene nonwoven SMMMS ehluza ukuya kuthi ga kwi-95% yamasuntswana amahle.

Ke ngoko, sifumanise ukuba iimaski ezinokwahlukanisa intsholongwane ngokwenene kufuneka zenziwe ngezinto ezithile, kwaye ayizizo zonke izixhobo ezifanelekileyo kwiimaski.
Okokugqibela, i-ORIENTMED sithemba ngokunyanisekileyo ukuba wonke umntu unokuzigcina ukhuselekile kwaye usempilweni.
