Kule mihla, iimaski ziye zaba zezinye zezinto eziyimfuneko ukuba abantu baphume. Kunokuqikelelwa ukuba ukonyuka kwemfuno yentengiso kuthetha ukuba amandla okuvelisa iimaski aya kunyuka, kwaye abavelisi nabo baya kunyuka. Uvavanyo lomgangatho wemaski lube yinkxalabo eqhelekileyo.
Uvavanyo lweemaski zokhuselo lwezonyango Umgangatho wovavanyo yi-GB 19083-2010 IiMfuno zobugcisa kwiiMaski zoKhuseleko lwezoNyango. Izinto eziphambili zokuvavanya zibandakanya uvavanyo lweemfuno ezisisiseko, ukubopha, ukuvavanywa kwempumlo, uvavanyo lwe-mask band, ukusebenza kakuhle kokucoca, uvavanyo lokumelana nokuhamba komoya, uvavanyo lokungena kwegazi lokwenziwa, uvavanyo lokuchasa ukufuma komhlaba, intsalela ye-ethylene oxide, uvavanyo lokusebenza lokubuyiswa komlilo, uvavanyo lokusebenza olucaphukisa ulusu, izibonakaliso zokuvavanya i-microbial, njl. Izinto zokufumanisa i-microbial ikakhulu ziquka inani elipheleleyo leekoloni zebhaktheriya, i-coliforms, i-pseudomonas aeruginosa, i-Staphylococcus aureus, i-hemolytic streptococcus, inani elipheleleyo lamakholoni efungal kunye nezinye izibonakaliso.
Uvavanyo lwemaski oluqhelekileyo olukhuselayo Umgangatho wokuvavanya yi-GB/T 32610-2016 Inkcazo yobuGcisa yeeMaski zoKhuseleko lwemihla ngemihla. Izinto zokubhaqa zibandakanya ikakhulu ukufumanisa iimfuno ezisisiseko, ukubonwa kweemfuno zembonakalo, ukubonwa komgangatho wangaphakathi, ukusebenza kakuhle kokucoca kunye nefuthe lokukhusela. Uvavanyo lomgangatho wangaphakathi wezi projekthi kukuhlikihla ukukhawuleza, umxholo we-formaldehyde, ixabiso le-pH, unokubola umxholo wedayi ye-amine enevumba elimnandi, iintsalela ze-epoxy ethane, ukuxhathisa okuphefumlelayo, ukumelana nokuphelelwa umoya, ibhanti lemaski kunye nokomelela kokwaphuka kunye nendawo yekhonkco lomzimba, ukuqina kwevalve yokuphefumla. , i-microbial fluid (iqela le-coliform kunye neebhaktheriya ze-pathogenic, i-fungi colony total, inani elipheleleyo lamakholoni ebhaktheriya).
Uvavanyo lwephepha lemaski Umgangatho wokufumanisa yi-GB/T 22927-2008 Mask Paper. Ezona zinto zovavanyo ziphambili zibandakanya ukuqina, amandla okuqina, ukungenwa komoya, amandla okuqina okumanzi ixesha elide, ukuqaqamba, uthuli, izinto zefluorescent, ukufuma okuziswayo, izikhombisi zococeko, izinto ezikrwada, inkangeleko, njl.
Ukufunyanwa kweemaski zonyango ezilahlwayo Umgangatho wovavanyo wawuyi-YY/T 0969-2013 Disposable Medical Masks. Izinto eziphambili zokuvavanya zibandakanya ukubonakala, ukwakheka kunye nobukhulu, i-clip yempumlo, i-mask band, ukusebenza kakuhle kwe-bacterial filtration, ukumelana ne-ventilation, izikhombisi ze-microbial, i-ethylene oxide intsalela kunye novavanyo lwe-biological. Izalathisi ze-microbial ikakhulu zichonge inani elipheleleyo lee-bacterial colonies, coliforms, pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococcus kunye nefungi. Izinto zovavanyo lwebhayoloji ziquka i-cytotoxicity, ukucaphuka kwesikhumba, ukulibaziseka kwe-hypersensitivity reaction, njl.
Uvavanyo lwemaski ezinithiweyo Umgangatho wokuvavanya nguFZ/T 73049-2014 Knitted Mask. Izinto zokubhaqa ikakhulu ziquka umgangatho wenkangeleko, umgangatho wangaphakathi, ixabiso le-pH, umxholo we-formaldehyde, ukubola kwedayi ye-amine enevumba elimnandi, umxholo wefayibha, ukukhawuleza kombala ekuhlambeni isepha, ukukhawuleza kwamanzi, ukukhawuleza kwamathe, ukukhawuleza ukukhuhlana, ukubila, ukuphefumla komoya, ivumba, njl.
PM2.5 ukufunyaniswa kwemaski ekhuselayo Umgangatho wokufumanisa wawuyi-T/CTCA 1-2015 PM2.5 IiMaski eziKhuselayo kunye ne-TAJ 1001-2015 PM2.5 iiMaski eziKhuselayo. Izinto eziphambili zokubhaqa zibandakanya ukubonwa okubonakalayo, i-formaldehyde, ixabiso le-pH, ubushushu kunye nokufuma kwe-pretreatment, iidayi ze-ammonia ezinokubola, izibonakaliso ze-microbial, ukusebenza kakuhle kokucoca, izinga lokuvuza lilonke, ukuxhathisa ukuphefumla, i-mask lacing kunye noqhagamshelo lomzimba oluphambili, indawo efileyo, njl. .
