Abantu abaningi kungenzeka ukuthi bake baba nalezi zindaba: Ngisho noma amafasitela evaliwe, imvula isangena endlini futhi umsindo wezimoto emgwaqweni ongezansi uzwakala kahle ekhaya. Lokhu kungenzeka ukuthi kuwukwehluleka kwesivalo somnyango nefasitela!
Nakubaisivalo se-siliconeiyinto ewusizo kuphela enqubweni yokukhiqiza amafasitela, ibalwa ngengxenye encane yezindleko, idlala indima ebaluleke kakhulu ekusebenzeni kwamafasitela, ikakhulukazi ekuqineni kwamanzi, ukungabi nomoya, ukuvala ukushisa, ukuvala umsindo, njll. Akufanele ithathwe kancane. Uma i-silicone sealant inezinkinga zekhwalithi, izobangela izinkinga ezifana nokuvuza kwamanzi nokuvuza komoya, okuzothinta kakhulu ukuvala umoya nokuvaleka kwamanzi kweminyango namafasitela.
Ngakho-ke hlobo luni lwe-silicone olusebenzisayo kumafasitela?
1. Khetha kahle imikhiqizo ehlangabezana nezindinganiso
Enqubweni yokukhetha i-silicone sealant, ngaphezu kwezindinganiso ehlangabezana nazo, kufanele kuqashelwe nezinga layo lokufuduka elihambisanayo. Umthamo wokufuduka uyisibonakaliso esibaluleke kakhulu sokulinganisa ukunwebeka kwe-sealant. Uma umthamo wokufuduka uphakeme, kulapho ukunwebeka kwe-sealant kuba ngcono khona. Ukuze kucutshungulwe futhi kufakwe amafasitela, imikhiqizo enekhono lokufuduka elingaphansi kuka-12.5 kufanele ikhethwe ukuqinisekisa ukuqina komoya isikhathi eside kanye nokuqina kwamanzi kwamafasitela.
Ngesikhathi sokufakwa nokusetshenziswa kwamafasitela, umphumela wokubopha phakathi kwama-sealant avamile kanye nokhonkolo wesamente uvame ukuba mubi kakhulu kunalowo onamaphrofayili e-aluminium noma ingilazi yeminyango namafasitela. Ngakho-ke, kufaneleka kakhulu ukusebenzisa i-sealant esetshenziselwa ukufakwa kwamafasitela eShayina ukuze kuhambisane ne-JC/T 881.
Imikhiqizo enamazinga aphezulu okufuduka inamandla amakhulu okubekezelela izinguquko ekufudukeni kwamalunga. Kunconywa ukukhetha imikhiqizo enamazinga aphezulu okufuduka ngangokunokwenzeka.
2. Khetha kahle imikhiqizo ye-sealant ngokuya ngesicelo
Amafasitela ozimele afihliwe kanye namafeni okuvula ozimele afihliwe adinga isivali sokwakheka ukuze sidlale indima yokubopha kwesakhiwo. Isivali sokwakheka se-silicone kumele sisetshenziswe, futhi ububanzi nobukhulu baso bokubopha kumele kuhlangabezane nezidingo zomklamo.
Enqubweni yokufaka umnyango namafasitela, isivali esisetshenziselwa ukuhlangana kwamatshe noma ukuhlangana okunetshe ohlangothini olulodwa kufanele sibe isivali esikhethekile setshe esihlangabezana nezindinganiso ze-GB/T 23261.
Kumafasitela namafasitela angashi noma iminyango namafasitela angaphandle adinga ukuqina okungashi, kungcono ukusebenzisa izinto zokuvala umlilo ezingashi.
Ezindaweni zokufaka izicelo ezinezidingo ezikhethekile zokumelana nokubola, njengekhishi, izindlu zangasese kanye nezindawo ezimnyama nezinomswakama, kufanele kusetshenziswe izinto zokuvala iminyango namafasitela ezingangenwa ukubola.
3. Ungakhethi izithiyo ze-silicone ezigcwele uwoyela!
Njengamanje, kunezivalo eziningi zeminyango namafasitela ezigcwele uwoyela emakethe. Le mikhiqizo igcwele uwoyela wamaminerali omningi futhi ayinamandla okuguga kahle, okuzoholela ezinkingeni eziningi zekhwalithi.
Ama-silicone sealants afakwe uwoyela wamaminerali aziwa embonini ngokuthi “ama-silicone sealants anwetshiwe ngowoyela”. Uwoyela wamaminerali uyi-alkane petroleum distillate egcwele i-alkane petroleum. Ngenxa yokuthi isakhiwo sawo sama-molecule sihluke kakhulu kwese-silicone, asihambisani kahle nohlelo lwe-silicone sealant, futhi sizohamba futhi singene kusuka ku-silicone sealant ngemva kwesikhathi esithile. Ngakho-ke, “i-oil-filled sealant” inokuqina okuhle ekuqaleni, kodwa ngemva kwesikhathi sokusetshenziswa, uwoyela wamaminerali ogcwele uyahamba futhi angene kusuka ku-sealant, futhi i-sealant iyancipha, iqine, iqhekeke, futhi kukhona nenkinga yokungabophi.
