Uhlelo lokuqedela kokugcina okungaphandle (ama-EIFs)
I-Hydroxypropyl Methylcellulose (HPMC) iyi-polymer esolulekayo enamanzi etholakala ku-cellulose, evame ukusetshenziswa njengezengezo ezintweni ezahlukahlukene zokwakha, kufaka phakathi ukufakwa kwangaphandle nezinhlelo zokuqeda (ama-EIF). Uhlelo lokuqedwa kokugcina okungaphandle (ama-EIFs), elaziwa nangokuthi i-EWI (ingaphandle le-Insulation Systems) noma ama-armal yangaphandle okufakwayo kwe-incosite accosite systems (ETICS), ingabe udonga lwangaphandle lokufakwa kwe-incurtal (ETICS), luyindawo yokufakelwa yangaphandle engaphandle esebenzisa isikhumba sangaphandle sodonga.
Ngakho-ke, zonke ezinye izingxenye zodonga lwangaphandle kumele zibe yizithiyo zohlobo lwezinhlelo noma zivalwe kahle futhi zikhanyiselwe ukuze zivimbele amanzi kusuka ngemuva kwama-eIFs nasezindongeni ezingaphansi noma ngezinga eliphansi. Ama-WALL DRAINAGE EIFS Systems afana nezindonga ze-cavity; zifakwe ngaphezulu kwesithiyo sezulu ngemuva kokufakwa okusebenza njengendiza yokudonsa kwesibili. Isithiyo sezulu kufanele sikhanyiselwe kahle futhi sihlanganiswe nazo zonke ezinye izingxenye zodonga lwangaphandle ukuvikela amanzi ekuhambeni izindonga ezingaphansi noma phakathi.
Kuyini ukufakwa kwe-EIFS kwenziwa?
Ukufakwa ngokujwayelekile kuqukethe i-polystyrere enwetshiwe (i-XPS) futhi inamathiselwe ngomshini kwi-sheaning kanye noma noma isakhiwo sodonga. I-EIFS iyatholakala ezinhlotsheni ezimbili eziyisisekelo: uhlelo lwaseBarrier Wall noma uhlelo lokudonsa odongeni.
Ungacindezela ukuwaza ama-EIFs?
Ukuhlanza ama-EIFs kufanele kwenziwe ngochwepheshe onekhono. Indlela engcono yokuhlanza i-EIFS ukusebenzisa ivolumu yamanzi aphezulu ehambisana nengcindezi yamanzi ephansi kanye nezihlanza ezingabi nambitheka. Musa ukusebenzisa amakhemikhali we-caustic noma amasu wokuhlanza wokuhlanza, azolimaza unomphela ekugcineni.
Imikhiqizo ye-Cellose Cellulose ether ingasetshenziswa kabanzi ngodaka olunamathela kanye nohlobo lokushumeka ku-EIFS. Kungenza odongeni abe nokuvumelana okufanele, hhayi ukugcona, hhayi okunamathelayo ku-trowel esetshenziswayo, zizwe ukusebenziseka okukhanyayo futhi okubushelelezi ngesikhathi sokusebenza, okulula ukunyakaza ngokuphazamiseka nokugcina amaphethini aqediwe.
