Zeziphi iimeko ezifunekayo kwi-FFP2 imaski yokucoca imidiya|KENJOY

FFP2 imaskiluhlobo lweemveliso zococeko, ezidla ngokunxitywa emlonyeni nasempumlweni ukuhluza umoya emlonyeni nasempumlweni, ukuze kuthintelwe iigesi eziyingozi, amavumba, amathontsi, iintsholongwane kunye nezinye izinto, ezenziwe ngegawusi okanye iphepha kunye nezinye izinto. .

I-FFP2 imaski inefuthe elithile lokucoca emoyeni ongena emiphungeni.Xa izifo ezithathelwanayo zokuphefumula zixhaphake, xa usebenza kwindawo engcolileyo njengothuli, ukugqoka imaski kunomphumo omhle kakhulu.Iimaski zeFFP2 zinokwahlulwa zibe ziimaski zokucoca umoya kunye neemaski zokubonelela ngomoya.

NgoJanuwari 14, 2021, iOfisi yoLwazi yeBhunga leSizwe yabamba inkomfa yabezindaba ukwazisa ukuthunyelwa kwe-China kwe-224.2 yeebhiliyoni zeemaski ngo-2020. Ngomhla we-11 kaFebruwari, uLawulo Jikelele loLawulo lweMarike kunye namanye amasebe amane adityanisiwe ukuba aphinde asasaze kwaye aqinise -ubunzulu bokukhuthaza ulongamelo lomgangatho wemaski.

Imathiriyeli yokucoca imaski

Kwisixhobo sokucoca imaski ekhuselayo ye-FFP2, kufuneka ibe nezi meko zintathu zilandelayo: okokuqala, xa imaski ihambelana kakuhle nobuso bomsebenzisi, ukusebenza kakuhle kokucoca kuphezulu, okwesibini kukunganyangeki okuphantsi kokuphefumla, kwaye okwesithathu kukuba umsebenzisi. uziva ekhululekile.Izinto zokucoca imaski yothuli zenziwe ngezinto ezahlukeneyo, kubandakanya amalaphu aqhelekileyo, iinwele zezilwanyana, amalaphu angalukwanga njalo njalo.Uhlobo lwezinto ezizivayo zekhabhoni zithandwa kakhulu kumgangatho wesizwe.

Ubume bemaski ye-gauze ayihambelani kakuhle nobuso bomntu, kwaye amasuntswana amaninzi asenza umonakalo omkhulu kuthi aya kungena kwindlela yokuphefumla emiphungeni ngomsantsa ophakathi kwemaski kunye nobuso, kwaye imathiriyeli yokucoca ngokubanzi iyinto yomatshini. ilaphu.ukuze kuphunyezwe ukusebenza kakuhle kokuthintela uthuli, ekuphela kwendlela yokwandisa ukutyeba kukwandisa ubukhulu, kwaye isiphumo esibi sokwandisa ubukhulu kukwenza umsebenzisi azive exhathisa ukuphefumla kwaye azive engakhululekanga.Ilaphu elingalukwanga elenziwe nge-electrostatic alinakuvimba kuphela amasuntswana othuli olukhulu, kodwa kunye nentlawulo ye-electrostatic encanyathiselwe kumphezulu wayo inokuthengisa uthuli olucolekileyo ngomxhuzulane we-electrostatic ukufezekisa ukusebenza kakuhle kokucinezelwa kothuli.Ngakolunye uhlangothi, ubukhulu bezinto zokucoca zincinci kakhulu, ezinciphisa kakhulu ukuxhathisa ukuphefumla komsebenzisi kwaye uzive ukhululekile, ngaloo ndlela ufezekisela iimeko ezintathu eziyimfuneko zeendaba ezilungileyo zokucoca ezikhankanywe ngasentla.Ngemathiriyeli yokucoca elungileyo kunye nolwakhiwo lwemaski eyilwe ngokwesayensi, imaski esebenzayo nekumgangatho ophezulu iyenziwa.

Isiphumo esifanelekileyo

Imaski ye-FFP2 kufuneka ibe yisayizi elungileyo kwaye inxitywe ngokuchanekileyo ukuze imaski isebenze.Iimaski ezithengiswa kwimarike zihlala zohlulwe ngokwemaski ezixande kunye nezekomityi.Imaski yoxande kufuneka ibe nesakhiwo ubuncinane semigangatho emithathu yephepha ukwenzela ukuba ibe nefuthe lokukhusela.Abasebenzisi kufuneka bacinezele ucingo kwi-FFP2 imaski kwibhulorho yempumlo kwaye basasaze imaski yonke ecaleni kwebhulorho yempumlo ukuze isebenze.Ngaba ukuvumela umntwana ukuba anxibe imaski yotyando oluxande, kuba ayinayo imilo emiselweyo, ukuba ibotshwe kakuhle, inokunamathela ebusweni bomntwana.Imaski yekomityi kufuneka iqinisekise ukuba imaski ixinene ngokwaneleyo emva kokuba incanyathiselwe ebusweni ukuze umoya ophumileyo ungaphumi ukuze usebenze.Xa unxibe imaski yekomityi, zama ukuvuthela ngezandla zakho phezu kwemaski ukuze ubone ukuba kukho umoya ovuzayo kumda wemaski yeFFP2.Ukuba isigqubuthelo semaski seFFP2 asiqinile, simise kwakhona phambi kokuba usinxibe.

Oku kungasentla kukungeniswa kweziphi iimeko ezifunekayo kwi-FFP2 imaski yokucoca imidiya.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeFFP2, nceda uzive ukhululekile ukuqhagamshelana nathiumthengisi wemaski.
