I-Water Vapor Permeability - Ukungqubuzana Phakathi Kokwahlukaniswa Kwezingubo Zokuzivikela kanye Nenduduzo
Ngokwencazelo esezingeni likazwelonke le-GB 19082-2009 “Izimfuneko Zobuchwepheshe Zezingubo Zokuzivikela Ezilahlwayo Zezokwelapha”, izingubo zokuzivikela ziyizingubo zochwepheshe ezinikeza umgoqo nesivikelo kubasebenzi bezokwelapha lapho behlangana negazi lesiguli okungenzeka libe nezifo ezithathelwanayo, uketshezi lomzimba, uketshezi. , kanye nezinhlayiyana ezisemoyeni. Kungashiwo ukuthi "umsebenzi wesithiyo" yisistimu yenkomba yokusebenza eyisihluthulelo yezingubo zokuzivikela, njengokumelana namanzi, ukumelana nokungena ngegazi lokwenziwa, i-surface hydrophobicity, umphumela wokuhlunga (ukuvinjelwa kwezinhlayiyana ezingezona amafutha), njll.
Uma kuqhathaniswa nalezi zinkomba, kunenkomba eyodwa ehluke kancane, okungukuthi "ukungena komphunga wamanzi" - imele ukufinyeleleka kwezingubo zokuzivikela kumhwamuko wamanzi. Kalula nje, ihlola ikhono lezingubo zokuzivikela ukuze liqondise ukuhwamuka komjuluko okhishwa umzimba womuntu. Ukuphakama komhwamuko wamanzi kwezingubo zokuzivikela, kukhulu ukukhululeka kokugcwala kanye nobunzima bokujuluka, okusiza kakhulu ukunethezeka kwabasebenzi bezokwelapha abazigqokile.
Isithiyo esisodwa, igebe elilodwa, ngezinga elithile, yizinkinga eziphikisanayo. Ukuthuthukiswa kwekhono elivimbelayo lezingubo zokuzivikela ngokuvamile kudela ingxenye yokungena, ukuze kuzuzwe ibhalansi phakathi kwakho kokubili, okungenye yezinjongo zocwaningo lwebhizinisi nokuthuthukiswa kanye nenhloso yasekuqaleni yezinga likazwelonke le-GB 19082-2009. Ngakho-ke, esilinganisweni, izidingo zokungena komhwamuko wamanzi wezimpahla zokuzivikela ezilahlwayo zivezwe ngokucacile: hhayi ngaphansi kuka-2500g/(m2 · 24h), kanye nendlela yokuhlola nayo inikeziwe.
Ukukhethwa Kwezimo Zokuhlola Zezingubo Zokuzivikela Zezinga Lokudluliswa Kwemphunga Wamanzi
Ngokusho kokuhlangenwe nakho kokuhlolwa komlobi kanye nemiphumela yocwaningo yezincwadi ezifanele, ukuvuthwa kwezindwangu eziningi ngokuvamile kukhuphuka ngokukhuphuka kwezinga lokushisa; kuyilapho izinga lokushisa lingaguquki, ukungena kwezindwangu ngokuvamile kuncipha ngokwanda komswakama ohlobene. Ngakho-ke, ukuvunyelwa kwesampula ehlolwe ngaphansi kwesimo esithile akukwazi ukumela ukuvuthwa kukalwa ngaphansi kwezinye izimo zokuhlola!
Izidingo zobuchwepheshe zezingubo zokuvikela ezilahlwayo ze-GB 19082-2009 zibeka ngokusobala izimfuneko zenkomba yokungena komhwamuko wempahla yezimpahla zokuvikela ezilahlwayo, kodwa azicacisi izimo zokuhlola. Umbhali uphinde wabuyekeza indlela yokuhlola ejwayelekile GB/T 12704.1, ehlinzeka ngezimo ezintathu zokuhlola: a, 38℃, 90%RH; b, 23℃, 50%RH; c, 20℃, 65%RH. Izinga lincoma ukuthi kusetshenziswe isimo a njengesimo sokuhlola esikhethwayo, njengoba sinomswakama ophakeme ohlobene nezinga lokungena elisheshayo, elifanele ukuhlolwa nokucwaninga elabhorethri. Uma kucatshangelwa indawo yangempela yokusetshenziswa kwezingubo zokuzivikela, kunconywa ukuthi amabhizinisi anekhono kufanele futhi enze isivivinyo ngaphansi kwesimo b (38℃, 50% RH) ukuze ahlinzeke ngokuhlolwa okubanzi kokungena komhwamuko wempahla yokuvikela.
Injani isudi yamanje yokuvikela “ukungenwa komhwamuko wamanzi”
Ngokusekelwe kokuhlangenwe nakho kokuhlolwa nezincwadi ezifanele ezitholakalayo, ukungeneka kwezinto ezisetshenziswayo nezakhiwo ezisetshenziswa kumasudi okuzivikela ngokuvamile kuba ngu-500g/(m2·24h) noma ngaphansi, kusukela ku-7000g/(m2·24h) noma ngaphezulu, futhi kugxilile kakhulu. phakathi kuka-1000 g/(m2·24h) no-3000g/(m2·24h). Njengamanje, ngenkathi kukhulisa amandla okukhiqiza ukuxazulula ukushoda kwezingubo zokuzivikela nezinye izinto zokuvikela nokulawula ubhubhane, izikhungo zocwaningo lochwepheshe kanye namabhizinisi bacabangele “induduzo” yabasebenzi bezokwelapha kanye nezingubo zokuzivikela ezilungiselelwe bona. Isibonelo, ukushisa kwesudi yokuzivikela kanye nobuchwepheshe bokulawula umswakama owenziwe yi-Huazhong University of Science and Technology isebenzisa ubuchwepheshe bokwelapha ukujikeleza komoya ukuze kususwe umswakama futhi kulawule izinga lokushisa ngaphakathi kwesudi yokuzivikela, igcine isomile futhi ithuthukise ukunethezeka kwabasebenzi bezokwelapha abagqoke.
Thumela umlayezo wakho kithi:
