TNazi izinto ezininzi zokukhusela ubushushu ezisingqongileyo, ngokwendlela ezisetyenziswa ngayo izihlandlo ezahlukeneyo zokwahlulahlula, ezifana nezinto eziqhelekileyo eziquka izixhobo zokukhusela ubushushu eluphahleni okanye izixhobo zokukhusela ubushushu bodonga lwangaphandle, ezijolise namhlanje kuhlu lwezinto zokukhusela ubushushu bodonga lwangaphandle kunye nohlu oluthile.
Ngenxa yophuhliso olukhawulezayo lwezakhiwo zanamhlanje, sineemfuno eziphezulu ngakumbi ekusebenzeni kodonga lwangaphandle. Sidinga ukufunda nokuvelisa izakhono ezintsha zepleyiti edityanisiweyo ezinefuthe elihle lokuthintela ukudumba, ukusebenza kakuhle kokutsha, ukhuseleko oluluhlaza kokusingqongileyo, kwaye ixabiso linokwamkelwa ngumntu wonke.
Umgangatho wethu wesizwe we-GB8624-97 wahlula ukusebenza kokutsha kwezixhobo zokwakha ngokwamanqanaba alandelayo:
1.Udidi: izixhobo zokwakha ezingatshiyo: phantse azikho izinto ezitshayo.
2.B1: izixhobo zokwakha ezitshayo: izixhobo ezitshayo zinefuthe elihle lokungatshisi ilangabi. Kunzima ukubamba umlilo emoyeni xa kukho ilangabi elivulekileyo okanye xa kukho ubushushu obuphezulu, akulula ukusasazeka ngokukhawuleza, kwaye xa umthombo womlilo ususiwe, ukutsha kuya kuyeka ngoko nangoko.
3.Inqanaba le-B2: izixhobo zokwakha ezinokutsha: izixhobo ezinokutsha zinefuthe elithile elithintela ilangatye. Emoyeni xa kukho umlilo ovulekileyo okanye phantsi kwesenzo sobushushu obuphezulu, umlilo uya kutsha ngoko nangoko, kulula ukukhokelela ekusasazeni komlilo, njengeepali zomthi, isakhelo somthi, imiqadi yomthi, izinyuko zomthi, njl.
4.B3: izixhobo zokwakha ezitshayo: azinasiphumo sokungatshisi ilangabi, kulula ukuzitshisa, umngcipheko omkhulu womlilo.
Izinto zokukhusela udonga zangaphandle zahlulwe ngokwereyithingi yomlilo:
1.ukusebenza kokutsha kwe-A grade yezixhobo zokukhusela: uboya belitye, uboya beglasi, iglasi yefoam, i-foam ceramic, isamente yefoam, i-perlite evaliweyo, njl.
2.ukusebenza kokutsha kwezinto zokwambathisa ze-B1 grade: emva konyango olukhethekileyo lwebhodi ye-polystyrene ekhutshiweyo (XPS)/ emva konyango olukhethekileyo lwe-polyurethane (PU), i-phenolic, ii-polystyrene eziphuma kwi-rubber powder, njl.njl.
3.ukusebenza kokutsha kwezinto zokwambathisa ze-B2 grade: ibhodi ye-polystyrene ebunjiweyo (EPS), ibhodi ye-polystyrene ekhutshiweyo (XPS), i-polyurethane (PU), i-polyethylene (PE), njl.
