Mvura Vapor Permeability - Kupokana pakati peChipfeko Chekudzivirira Kuzviparadzanisa uye Kunyaradza
Zvinoenderana netsanangudzo iri muyero yenyika GB 19082-2009 "Technical Requirements for Medical Disposable Protective Clothing", zvipfeko zvekudzivirira zvipfeko zvehunyanzvi zvinopa chipingamupinyi uye dziviriro kuvashandi vekurapa kana vasangana neropa remurwere rinogona kutapukira, mvura dzemuviri, zvakabuda. , uye zvinhu zviri mumhepo. Zvinogona kutaurwa kuti "barrier function" ndiyo yakakosha yekuita index system yezvipfeko zvekudzivirira, zvakadai sekudzivirira mvura, kuramba kupinda neropa rekugadzira, pamusoro pehydrophobicity, filtration effect (isina-oil particle blocking), nezvimwewo.
Kuenzaniswa nezviratidzo izvi, pane chimwe chiratidzo chakasiyana zvishoma, chinonzi "mvura vapor permeability" - inomiririra kupera kwezvipfeko zvinodzivirira kumhepo yemvura. Zvichitaurwa zviri nyore, inoongorora kugona kwembatya dzekudzivirira kutungamira kubuda kweziya rinoburitswa nemuviri wemunhu. Iyo yakakwirira yemhute yemvura permeability yezvipfeko zvekudzivirira, iyo yakakura kuzorora kwe stuffiness uye kuoma kwekudikitira, izvo zvinonyanya kubatsira kunyaradzo yevashandi vekurapa vakapfeka.
Chipingamupinyi chimwe, gwanza rimwe, kusvika kumwero wakati, zvinetso zvinopokanidzana. Iko kunatsiridzwa kwekugona kuvharidzira kwezvipfeko zvekudzivirira kazhinji kunopira chikamu chekupinda, kuitira kuti uwane chiyero pakati pezviviri, chinova chimwe chezvinangwa zvebhizinesi rekutsvagisa nekusimudzira uye chinangwa chepakutanga chenyika standard GB 19082-2009. Naizvozvo, muyero, izvo zvinodikanwa zvehuputi hwemvura permeability yezvokurapa zvinoraswa zvipfeko zvekudzivirira zvinotsanangurwa zvakajeka: kwete pasi pe2500g / (m2 · 24h), uye nzira yekuyedza inopiwawo.
Sarudzo Yekuyedza Mamiriro Ekudzivirira Kupfeka Mvura Vapor Transmission Rate
Zvinoenderana neruzivo rwekuedzwa kwemunyori uye mhedzisiro yekutsvagisa yemabhuku akakodzera, kupinza kwemachira mazhinji kunowanzo kuwedzera nekukwira kwekushisa; nepo tembiricha ichigara, kupenya kwemachira kunowanzo kuderera nekuwedzera kwehunyoro hunoenderana. Naizvozvo, iyo permeability yemuenzaniso yakaedzwa pasi peimwe mamiriro haigone kumiririra iyo permeability yakayerwa pasi pemamwe mamiriro ebvunzo!
Izvo zvinodiwa zvehunyanzvi zvekupfeka zvinoraswa zvekudzivirira zvekuchengetedza GB 19082-2009 zvinonyatso tsanangura iyo mvura vapor permeability index zvinodiwa zvezvinhu zvezvokurapa zvinoraswa zvipfeko zvekudzivirira, asi hazvitsanangure mamiriro ekuedzwa. Munyori akaongororawo nzira yekuedza chiyero GB/T 12704.1, iyo inopa mamiriro matatu ekuedzwa: a, 38℃, 90%RH; b, 23℃, 50%RH; c, 20 ℃, 65% RH. Iyo chiyero inokurudzira kushandisa chimiro a seyakasarudzika bvunzo mamiriro, sezvo iine hunyoro hwepamusoro uye kukurumidza kupinda mwero, iyo inokodzera kuongororwa murabhoritari uye kutsvagisa. Tichifunga nezveiyo chaiyo yekushandiswa nharaunda yezvipfeko zvekudzivirira, zvinokurudzirwa kuti mabhizinesi ane kugona aitewo bvunzo pasi pemamiriro b (38 ℃, 50% RH) kuti ipe ongororo yakazara yehuputi hwemvura permeability yemidziyo yekudzivirira.
Ko yazvino sutu yekudzivirira ndeye "mvura vapor permeability"
Zvichienderana neruzivo rwebvunzo uye anowanikwa akakodzera mabhuku, kupenya kwezvishandiso zvemazuva ese uye zvimiro zvinoshandiswa mumasutu ekudzivirira zvinowanzo kutenderera 500g/(m2 · 24h) kana kudzika, kubva pa7000g/(m2 · 24h) kana pamusoro, uye kazhinji yakatarisana. pakati pe1000 g/(m2 · 24h) uye 3000g/(m2 · 24h). Parizvino, tichiwedzera kugona kwekugadzira kugadzirisa kushomeka kwemasutu ekudzivirira uye zvimwe zvekudzivirira nekudzora denda, masangano ezvekutsvagisa ehunyanzvi nemabhizinesi akafunga nezve "kunyaradza" kwevashandi vekurapa uye akavagadzirira masutu ekudzivirira. Semuenzaniso, tekinoroji yekudzivirira sutu uye humidity control tekinoroji yakagadzirwa neHuazhong University yeScience uye Technology inoshandisa tekinoroji yekurapa kutenderera kwemhepo kubvisa unyoro uye kugadzirisa tembiricha mukati mesutu yekudzivirira, ichiichengeta yakaoma uye kuvandudza kunyaradzwa kwevashandi vekurapa vakaipfeka.
