Ukunyibilika komphunga waManzi-Ukuchasana phakathi kokwahlulwa kweMpahla eKhuselayo kunye nokuThuthuzelwa
Ngokwenkcazo kumgangatho wesizwe we-GB 19082-2009 "IiMfuno zobuGcisa kwiMpahla yoKhuseleko yezoNyango", iimpahla ezikhuselayo zizinxibo zobungcali ezibonelela ngomqobo kunye nokhuseleko kubasebenzi bezonyango xa bedibana negazi lesigulane esinosulelo, ulwelo lomzimba, imfihlo. , kunye nentwana esemoyeni. Kunokuthiwa "umsebenzi womqobo" yinkqubo yesalathisi esingundoqo sesalathisi sempahla yokukhusela, njengokuchasana kwamanzi, ukuchasana nokungena ngegazi lokwenziwa, i-surface hydrophobicity, i-filtration effect (i-particle non-oily blocking), njl.
Xa kuthelekiswa nezi zalathisi, kukho enye isalathisi esahluke kancinane, oko kukuthi "i-vapor vapor permeability" - imele ukunyanzeliswa kwempahla yokukhusela kwi-vapor yamanzi. Ukubeka nje ngokulula, ivavanya amandla empahla ekhuselayo ukukhokela ukuphuphuma kombilo okhutshwa ngumzimba womntu. Ukuphakama komphunga wamanzi okungena kwimpahla ekhuselayo, ukukhululeka okukhulu kwezinto kunye nobunzima bokubila, okwenza kube lula ukuthuthuzela abasebenzi bezonyango abanxibe.
Umqobo omnye, umsantsa omnye, ukusa kumlinganiselo othile, ziingxaki eziphikisanayo. Ukuphuculwa kwesakhono sokuthintela iimpahla ezikhuselayo ngokuqhelekileyo kubingelela inxalenye ye-permeability, ukuze kuphunyezwe ukulingana phakathi kwezi zibini, enye yeenjongo zophando lwamashishini kunye nophuhliso kunye nenjongo yokuqala yomgangatho wesizwe we-GB 19082-2009. Ngoko ke, kumgangatho, iimfuno zomphunga wamanzi ogqithisayo wempahla yokukhusela yokukhusela yonyango ichazwe ngokucacileyo: ingabi ngaphantsi kwe-2500g / (m2 · 24h), kunye nendlela yokuvavanya nayo inikwe.
Ukukhethwa kweMiqathango yoVavanyo lweMpahla yoKhuseleko lweNdawo yoThutho lwaManzi loMphunga
Ngokuhambelana namava ovavanyo lombhali kunye neziphumo zophando zoncwadi olufanelekileyo, ukunyanzeliswa kwamalaphu amaninzi kwandisa ngokunyuka kwamaqondo obushushu; ngelixa iqondo lobushushu lihlala lihleli, ukunyanzeliswa kwamalaphu kuncipha ngokubanzi ngokunyuka kokufuma. Ngoko ke, ukunyanzeliswa kwesampulu evavanyiweyo phantsi kwemeko ethile ayikwazi ukumela ukunyanzeliswa okulinganiselwe phantsi kwezinye iimeko zovavanyo!
Iimfuno zobugcisa zempahla yokhuselo elahlayo ye-GB 19082-2009 ichaza ngokucacileyo iimfuno zesalathiso sokungena komphunga wamanzi kwimpahla yempahla yokhuselo elahlayo, kodwa ayicacisi iimeko zovavanyo. Umbhali uphinde wahlaziya indlela yokuvavanya umgangatho we-GB / T 12704.1, obonelela ngeemeko ezintathu zovavanyo: a, 38℃, 90%RH; b, 23℃, 50%RH; c, 20℃, 65%RH. Umgangatho ucebisa ukuba kusetyenziswe imeko a njengeyona meko ikhethwayo yovavanyo, njengoko inomswakama ophezulu onxulumeneyo kunye nesantya sokungena ngokukhawuleza, esilungele uvavanyo lwebhubhoratri kunye nophando. Ukuthathela ingqalelo indawo eyiyo yokusetyenziswa kwempahla ekhuselayo, kucetyiswa ukuba amashishini anesakhono kufuneka enze uvavanyo phantsi komqathango we-b (38℃, 50% RH) ukunika uvandlakanyo olubanzi ngakumbi lokungena komphunga wempahla ekhuselayo.
Ingaba isuti yangoku ekhuselayo injani "ukungenwa komphunga wamanzi"
Ngokusekwe kumava ovavanyo kunye noncwadi olukhoyo olufanelekileyo, ukufikeleleka kwezinto eziphambili kunye nezakhiwo ezisetyenziswa kwiisuti ezikhuselayo zihlala zijikeleze i-500g / (m2 · 24h) okanye ngaphantsi, ukusuka kwi-7000g / (m2 · 24h) okanye ngaphezulu, kwaye ubukhulu becala bugxininiswe. phakathi kwe-1000 g/(m2 · 24h) kunye ne-3000g/(m2 · 24h). Okwangoku, ngelixa ukwandisa umthamo wemveliso ukusombulula ukunqongophala kweesuti zokukhusela kunye nezinye izinto zokuthintela kunye nokulawula ubhubhane, amaziko ophando lobuchwephesha kunye namashishini athathele ingqalelo "intuthuzelo" yabasebenzi bezonyango kunye neesuti zokukhusela ezilungiselelwe bona. Ngokomzekelo, i-suti yokukhusela i-suti yokushisa kunye neteknoloji yokulawula umswakama eyenziwe yi-Huazhong University of Science and Technology isebenzisa iteknoloji yonyango lokujikeleza komoya ukususa umswakama kunye nokulawula ubushushu ngaphakathi kwesuti yokukhusela, ukuyigcina yomile kwaye iphucula induduzo yabasebenzi bezonyango abanxibe.
Thumela umyalezo wakho kuthi:
