Ukuvunyelwa komswakama womoya kuyisici esibalulekile okufanele usicabangele lapho ukhetha izinto zokuvikela zokusetshenziswa okuhlukahlukene. Ngokusetshenziswa kwe-foam yerabha ye-NBR/PVC, ukuqonda ukuvunyelwa komswakama womoya wayo kubalulekile ekunqumeni ukusebenza kwayo ezindaweni ezahlukene.
Ukufakwa kwe-foam yerabha ye-NBR/PVC kuyinto esetshenziswa kabanzi embonini ye-HVAC, yezimoto kanye neyokwakha ngenxa yezakhiwo zayo ezinhle kakhulu zokufakwa kwe-insulation kanye nokuguquguquka. Kodwa-ke, enye yezinkinga ezibalulekile ezizungeze le nto ukuvuleka komswakama, noma ikhono lomhwamuko wamanzi lokudlula kuyo.
Ukumunca komswakama kwezinto zokuvikela i-foam yerabha ye-NBR/PVC kunqunywa ukwakheka kwayo kanye nesakhiwo sayo. I-NBR (irabha ye-acrylonitrile-butadiene) kanye ne-PVC (i-polyvinyl chloride) zombili ziyizinto zokwenziwa ezaziwa ngokumelana kwazo nomswakama. Uma zihlanganiswa nokuvikela i-foam, zakha isithiyo esiqinile nesingenamanzi esivimbela ngempumelelo ukungena komhwamuko wamanzi.
Isakhiwo samaseli avaliwe sokufakwa kwefoam yerabha ye-NBR/PVC sithuthukisa kakhulu ukusebenza kwayo okumelana nomswakama. Ngokungafani nokufakwa kwefoam yerabha ye-open-cell, okungamunca futhi kugcine umswakama, ukufakwa kwefoam yerabha ye-closed-cell kwakhiwe amaseli omoya avaliwe angavumeli umhwamuko wamanzi ukuthi udlule. Lokhu kwenza ukufakwa kwefoam yerabha ye-NBR/PVC kumelane kakhulu nomswakama, okwenza kube kuhle kakhulu ekusetshenzisweni lapho umswakama uyinkinga.
Ngaphezu kwalokho, ukufakelwa kwefoam yerabha ye-NBR/PVC kuvame ukumbozwa ngendawo evikelayo enikeza isithiyo esengeziwe somswakama. Ukufakelwa kungenziwa nge-aluminium foil, i-fiberglass, noma ezinye izinto ezithuthukisa ukumelana kokufakelwa komswakama nomhwamuko wamanzi. Ngokufaka lokhu kufakelwa komswakama ku-insulation, ukungena komswakama kwe-insulation yefoam yerabha ye-NBR/PVC kuncishiswa kakhulu, okwenza kufaneleke ukusetshenziswa ezindaweni ezinomswakama omningi noma ukusetshenziswa kwangaphandle.
Ngaphezu kokumelana nomswakama, ukufakelwa kwefoam yerabha ye-NBR/PVC kunikeza ezinye izinzuzo ezifana nokumelana nomlilo, ukufakelwa kwe-thermal kanye nokumuncwa komsindo. Lezi zakhiwo zenza kube ukukhetha okuguquguqukayo nokuthembekile kwezicelo ezahlukahlukene, kusukela ekufakweni kwe-air duct insulation ezinhlelweni ze-HVAC kuya ekufakweni kwe-duct insulation ezakhiweni zezimboni.
Uma ucabangela ukumuncwa komswakama kokufakwa kwe-foam yerabha ye-NBR/PVC, kubalulekile ukucabangela izidingo ezithile zokusetshenziswa. Isibonelo, ezindaweni ezinomswakama ophezulu noma ukuchayeka njalo kumswakama, kungadingeka ukhethe ukufakwa komswakama okujiyile noma okungenamoya ukuze kuqinisekiswe ukuvikeleka okwanele emhwameni wamanzi.
Ngamafuphi, ukufakelwa kwe-foam yerabha ye-NBR/PVC kunokungena komswakama okuphansi ngenxa yokwakheka kwayo, isakhiwo kanye nobuso obuvikelayo. Lokhu kwenza kube ukukhetha okufanele kwezicelo ezidinga ukumelana nomhwamuko wamanzi. Ngokuqonda ukungena komswakama komhwamuko walesi sici sokufakelwa, onjiniyela, osonkontileka kanye nabenzi bezinqumo bangenza izinqumo ezinolwazi lapho bekhetha izinto zokufakelwa kwamaphrojekthi abo, beqinisekisa ukusebenza kwesikhathi eside nokuqina.
