Wamkelekile kuThomas Insights - sipapasha iindaba zamva nje kunye nohlalutyo yonke imihla ukugcina abafundi bethu besazi ngentsingiselo yeshishini. Bhalisa apha ukuze uthumele izihloko zosuku ngqo kwibhokisi yakho.
Enye yeendlela ezilula nezincinci zokufezekisa uzinzo kwimizi-mveliso inokuba kukusebenzisa uphahla olupholileyo.
Ukwenza uphahla "lupholile" kulula njengokupeyinta kwibala lepeyinti emhlophe ukubonakalisa ukukhanya kunye nobushushu endaweni yokuyifunxa kwisakhiwo. Xa utshintsha okanye ubeka kwakhona uphahla, ukusetyenziswa kwezinto eziphuculweyo zokuphahla ezibonakalisiweyo endaweni yezinto zokuphahla zendabuko kunokunciphisa iindleko zomoya kunye nokunciphisa kakhulu ukusetyenziswa kwamandla.
Ukuba uqala ukusuka ekuqaleni kwaye ukwakha isakhiwo ukusuka ekuqaleni, ukufaka uphahla olupholileyo kuyinyathelo lokuqala elilungileyo; kwiimeko ezininzi, akukho xabiso elongezelelweyo xa kuthelekiswa nophahla lwemveli.
"Uphahla olubandayo" yenye yeendlela ezikhawulezayo kunye nezona ndleko ziphantsi kuthi zokunciphisa ukukhutshwa kwekhabhoni yehlabathi kwaye siqale iinzame zethu zokunciphisa utshintsho lwemozulu," watsho uSteven Zhu, owayesakuba nguNobhala wezaMandla wase-US.
Ukuba nophahla olupholileyo aluphuculi nje kuphela ukuqina, kodwa kunciphisa ukuqokelelwa komthwalo wokupholisa kunye "nempembelelo yesiqithi sokushisa kwedolophu". Kule meko, isixeko sishushu kakhulu kuneendawo ezisemaphandleni ezikufutshane. Ezinye izakhiwo zihlola uphahla oluluhlaza ukwenza iindawo zasezidolophini zizinzileyo.
Inkqubo yophahla iqulethwe ngamanqwanqwa amaninzi, kodwa i-exposure layer exposure yelanga inika uphahla uphawu "olupholileyo". Ngokwezikhokelo zeSebe lezaMandla zokukhetha uphahla olupholileyo, uphahla olumnyama lufunxa i-90% okanye ngaphezulu kwamandla elanga kwaye anokufikelela kumaqondo obushushu angaphezu kwe-150°F (66°C) ngamaxesha okukhanya kwelanga. Uphahla olunombala okhanyayo lufunxa ngaphantsi kwe-50% yamandla elanga.
Ipeyinti yophahla olupholileyo iyafana nepeyinti engqindilili kakhulu kwaye lukhetho olusebenzayo kakhulu lokonga amandla; akunyanzelekanga nokuba ibemhlophe. Imibala epholileyo ibonisa ukukhanya kwelanga okungaphezulu (40%) kunemibala efanayo emnyama efanayo (20%), kodwa isengaphantsi kunombala okhanyayo (80%). Iingubo ezipholileyo zophahla ziyakwazi ukumelana nemisebe ye-ultraviolet, iikhemikhali kunye namanzi, kwaye ekugqibeleni zandise ubomi bophahla.
Kuphahla olusezantsi, ungasebenzisa iziqhoboshi zoomatshini, izinto zokuncamathelisa, okanye iibhola zebhola ezinje ngamatye okanye iipava ukuze usebenzise iiphaneli zemembrane ezilungiselelwe ngaphambili eluphahleni. Uphahla oludibeneyo olubandayo lunokwakhiwa ngokufakela igrabile kwi-asphalt engangeni manzi umaleko, okanye ngokusebenzisa iipaneli ze-mineral surface ezinamasuntswana eminerali ekhanyayo okanye i-coatings efakwe kwifektri (oko kukuthi i-asphalt membranes elungisiweyo).
Esinye isisombululo esisebenzayo sophahla lokupholisa kukutshiza i-polyurethane foam. Iikhemikhali zolwelo zimbini ziyaxubana kwaye zandise ukwenza imathiriyeli engqindilili efana ne-styrofoam. Ibambelela eluphahleni kwaye emva koko igqunywe ngengubo ebandayo ekhuselayo.
Isisombululo se-ikholoji kuphahla oluthambekileyo ziishingles ezipholileyo. Uninzi lweentlobo ze-asphalt, iinkuni, iipolymer okanye iithayile zetsimbi zinokugqunywa ngexesha lemveliso yefektri ukubonelela ngomgangatho ophezulu wokubonisa. Udongwe, isileyiti, okanye uphahla lwethayile yekhonkrithi lunokubonakalisa ngokwendalo, okanye lunokunyangwa ukunika ukhuseleko olongezelelweyo. Isinyithi esingapeyintwanga sisibonakalisi esilungileyo selanga, kodwa ubushushu balo obukhuphayo buhlwempuzeke kakhulu, ngoko ke kufuneka bupeyintwe okanye bugqunywe ngengubo epholileyo ebonakalisayo ukuze kuzuzwe uphahla olupholileyo.
Iipaneli zelanga ziyisisombululo esiluhlaza ngokumangalisayo, kodwa ngokuqhelekileyo aziboneleli ngokufanelekileyo ukhuseleko lwemozulu yophahla kwaye azikwazi kuthathwa njengesisombululo sophahla olupholileyo. Uphahla oluninzi alufanelekanga ukufaka iipaneli zelanga. Ukwakhiwa kwezicelo ze-photovoltaics (iipaneli zelanga zophahla) zinokuba yimpendulo, kodwa oku kusephantsi kophando olongezelelweyo.
Abona badlali baphambili ababetha imakethi yophahla olubandayo lwehlabathi nguOwens Corning, iNkampani yeTeed, iGAF Materials Corporation, TAMKO Building Products Inc., IKO Industries Ltd., ATAS International Inc., Henry Company, PABCO Building Products, LLC., Malarkey Roofing Companies like I-Polyglass SpA kunye ne-Polyglass SpA zilawula izinto ezintsha zamva nje kuphahla olupholileyo, kwaye zisebenzise ubugcisa obuphezulu obufana ne-drones ukubona iindawo ezinengxaki kunye nokuchonga iingozi zokhuseleko; babonisa abathengi babo ezona zisombululo ziluhlaza.
Ngokunyuka okukhulu komdla kunye nemfuno yokuzinza, iteknoloji yophahla olupholileyo luhlala luhlaziywa kwaye luphuhliswa.
