Uphononongo lwaseKhanada oluphanda ukusebenza kwexesha elide le-polystyrene eyandisiweyo (EPS) ekudibaneni nomhlaba yenza abavelisi be-EPS baseMntla Melika naseKhanada bathi ukugquma kukulungele ukusetyenziswa emhlabeni, kufana nokusebenza kwepolystyrene ekhutshiweyo (XPS). ).
Emva koko, ngokusekelwe kubungqina bokungaphumeleli kwe-shingle, izifundo ezixhaswe yi-industry zibonise ukuba ukusebenza kwe-XPS kwizicelo zehlabathi zangempela azihambelani novavanyo lwebhubhoratri, okwenza i-EPS ibe yimpahla yeprimiyamu. Ngelixa ishishini le-XPS lizikhabile ezi ziphumo ngophando lwazo, inika umdla into yokuba abavelisi be-XPS balususile ugxininiso lwabo kwi-hygroscopicity ephantsi ebonwa kuntywiliselo lwaselabhoratri kunye neemeko zomoya ezifumileyo ukuya kwiipropathi zokusasazwa kokufuma kwe-XPS.
Uninzi lweentsilelo ze-XPS zibangelwa iimeko ezinzima zokufakela i-shingle kunye nokusetyenziswa kwezinto ezidityanisiweyo kunye ne-membrane esemgangathweni yokukhusela amanzi. Kukho ubungqina bokuba i-XPS ingcono xa kungekho mijelo ejikelezileyo ejikelezileyo kwaye iphantsi kwe-insulation, inikezela ukuxhathisa ukufuma xa udibana nomhlaba.
I-EPS ye-perimeter insulation ifakwe ngokwesiko kunye ne-backfill ye-drain material, i-polyethylene yokukhusela i-foam, kunye nemibhobho yokukhupha phantsi kwe-insulation. Nangona kunjalo, i-XPS ifakwe kuphela kusetyenziswa i-polyethylene membranes.
Ukubunjwa kwe-EPS kunye ne-XPS ye-insulation itshintshile ngokuhamba kwexesha, umzekelo, ii-agent ezivuthelayo zombini izinto zitshintshile. ENyakatho Melika naseKhanada, i-XPS okwangoku yenziwe ngaphandle kwe-ozone yokutshabalalisa i-agent evuthelayo, kodwa oku akunjalo kwenye indawo. Ezinye iimveliso ze-XPS ezingeniswe eNew Zealand zibonakala ngathi zenziwe ngokusika izinto ezikhululekileyo endaweni yokuyikhupha kubunzima besikhumba. I-cuticle kwiphepha le-XPS inciphisa ukuguga kwaye inegalelo elikhulu ekugcineni ukufuma.
I-BRANZ ivavanye imveliso ye-XPS kunye ne-thermal conductivity ye-0.036 W / mK. Ngokwahlukileyo, i-conductivity ye-carbon-filled polystyrene foam iphantsi kakhulu kuneli xabiso. Uninzi lwe-styrofoam eveliswe eNew Zealand iqulethe izinto ezisetyenzisiweyo kwaye ngamanye amaxesha ingaba nesakhiwo esinemingxuma engaphezulu.
Ukuvumela umswakama ukuba usasazeke emhlabeni, ngokufanelekileyo i-foam akufanele igqunywe ngokupheleleyo ngumqobo ongenamanzi. Ebusika, nakuphi na ukufuma kwisiseko sodonga kuya kunyanzeliswa ngaphandle kwi-perimeter insulation, ngoko ke kungcono ukusebenzisa umqobo we-steam ngaphandle kwe-insulation. Ukuba oku akunakwenzeka, i-foam kufuneka ingene emhlabeni, ishiye kuphela umaleko okhuselekileyo okhuselekileyo kumacandelo angaphezulu komhlaba.
Njengomgaqo oqhelekileyo, umxholo wamanzi wesiseko akufanele ube phezulu kakhulu, ngoko ke umngcipheko omkhulu wokubuyisela ukubuyisela uvela kwimpembelelo ye-capillary xa amanzi engena phakathi kwe-insulation kunye nekhonkrithi. Oku kunokuphetshwa ngokusebenzisa ikhefu le-capillary (umzekelo, i-butyl tape) kumphetho ongezantsi wesigqubuthelo.
Bhalisa ukuze ufumane zonke iindaba, uphononongo, izixhobo, uphononongo kunye nezimvo malunga noyilo kunye noyilo ngqo kwibhokisi yakho.
