Ingabe ukhethe i-silicone sealant efanele yezicabha namafasitela?

Uma i-silicone sealant inezinkinga zekhwalithi, izoholela ekuvuzeni kwamanzi, ukuvuza komoya nezinye izinkinga, okuzothinta kakhulu ukuqina komoya nokuqina kwamanzi eminyango namafasitela.

Imifantu nokuvuza kwamanzi okubangelwa ukwehluleka kwesivalo somnyango newindi

Ngakho-ke sikhetha kanjani i-sealant efanele yeminyango namafasitela?

1. Khetha kahle imikhiqizo ehlangabezana nezindinganiso

Ngesikhathi sokukhethwa kwe-sealant, ukunakwa akufanele kukhokhwe kuphela ezingeni elihlangabezana nalo, kodwa futhi nezinga elihambisanayo lokufuduka.Umthamo wokufuduka uyinkomba ebaluleke kakhulu yokukala ukunwebeka kwe-sealant.Ukuphakama komthamo wokufuduka, kuba ngcono ukunwebeka kwe-silicone sealant.Ukucutshungulwa nokufakwa kwezicabha namafasitela kufanele kukhethe imikhiqizo enekhono lokufuduka elingekho ngaphansi kuka-12.5 ukuze kuqinisekiswe ukucinana komoya kwesikhathi eside kanye nokucinana kwamanzi eminyango namafasitela.

Ngesikhathi sokufakwa nokusetshenziswa kweminyango namafasitela, umphumela wokuhlanganisa phakathi kwe-sealant evamile kanye nokhonkolo usimende uvame ukuba mubi kakhulu kunalokho okunamaphrofayili e-aluminium noma ingilazi yeminyango namafasitela.Ngakho-ke, kufaneleka kakhulu ukukhetha imikhiqizo evumelana ne-JC/T 881 njengesivalo sokufakwa kwezicabha namafasitela.

Imikhiqizo enezinga eliphezulu lokufuduka inamandla aqinile okumelana nezinguquko zokufuduka ngokuhlanganyela.Kunconywa ukukhetha imikhiqizo enezinga eliphezulu lokufuduka ngangokunokwenzeka.

2. Khethai-siliconeimikhiqizo ye-sealant ngendlela efanele ngokwenhloso

Amawindi ozimele afihliwe namafeni okuvula uhlaka olufihliwe adinga i-structural sealant ukuze adlale indima yokuhlanganisa isakhiwo.I-Silicone structural sealant kufanele isetshenziswe, futhi ububanzi bayo bokubopha kanye nobukhulu kufanele buhlangabezane nezidingo zokuklama.

Ngesikhathi sokufakwa kweminyango namafasitela, isivalo samalunga amatshe noma amalunga anetshe ohlangothini olulodwa sizoba isigxivizo esikhethekile setshe esihlangabezana nezinga le-GB/T 23261.

I-fireproof sealant ifaneleka kakhulu iminyango namafasitela angashi noma iminyango yangaphandle namafasitela ezakhiwo adinga ubuqotho bomlilo.

Ezindaweni zokufaka izicelo ezinezidingo ezikhethekile zokuvimbela isikhunta, njengamakhishi, okugeza okuhlanzekile kanye nezingxenye ezimnyama nezimanzi, ukuvala umnyango namafasitela amalunga kufanele kusetshenziswe isivalo sobufakazi besikhunta.

3. Ungakhethi i-silicone sealant egcwele amafutha!

Njengamanje, imakethe igcwele inani elikhulu lamafutha agcwele umnyango namafasitela ama-sealants, agcwele inani elikhulu lamafutha amaminerali futhi anokumelana nokuguga okubi, okuzoholela ezinkingeni eziningi zekhwalithi.

I-Silicone sealant exutshwe namafutha amaminerali ibizwa ngokuthi "i-oil fill silicone sealant" embonini.Amafutha amaminerali ayingxenye ye-saturated alkane petroleum distillation.Ngenxa yokuthi ukwakheka kwayo kwamangqamuzana kuhluke kakhulu kune-silicone, ukuhambisana kwayo nesistimu ye-silicone sealant akulungile, futhi izofuduka futhi ingene ngaphandle kwe-silicone sealant ngemva kwesikhathi esithile.Ngakho-ke, "i-sealant egcwele uwoyela" inokuqina okuhle ekuqaleni, kepha ngemuva kokusebenzisa isikhathi esithile, uwoyela wamaminerali ogcwele uyafuduka futhi ungene ku-sealant, futhi i-sealant izoncipha, ibe lukhuni, iqhekeke, futhi ibe nenkinga okungahlangani.

Iningi lama-silicone sealant ashibhile emakethe agcwele uwoyela wamaminerali, futhi okuqukethwe kwe-silicone eyisisekelo se-polymer kungaphansi kakhulu kwama-50%, kanti amanye angaphansi kwama-20%.

Uma i-sealant yefasitela lokugcwalisa igesi ithintana nengilazi ye-insulating, uwoyela wamaminerali ogcwele uzofuduka futhi ungene engilazini yokushisa, okuholela ekuhlakazweni kwerabha ye-butyl evala ingilazi ye-insulating kanye nokugeleza kukawoyela.

Khetha imikhiqizo yekhwalithi ephezulu ye-sealant.Nakuba intengo ye-sealant ethengwe esigabeni sokuqala iphakeme kancane, ukusebenza kwayo kungagcinwa isikhathi eside ngaphandle kwezinkinga zekhwalithi.Khetha ikhwalithi ephansi yezinga eliphansi "i-oil egcwele i-sealant", nakuba intengo ishibhile, izindleko zokuqala zokutshala izimali ziphansi kancane;Kodwa-ke, ngemva kokwenzeka kwezinkinga, izindleko zokulungisa kamuva, izindleko zomkhiqizo, izindleko zabasebenzi, ukulahleka komkhiqizo, njll. ngesikhathi sokusebenza kabusha kungase kube izikhathi eziningana noma izikhathi eziningi inani le-sealant ngokwayo;Ayigcinanga nje kuphela imali, kodwa yengeze izinkinga eziningi kubasebenzisi.
