Kungenzeka ukuthi abantu abaningi baye baba nalezi zimo: Nakuba amafasitela evaliwe, imvula isalokhu ingena ekhaya futhi umlozi wezimoto emgwaqeni ongezansi uzwakala kahle ekhaya.Lokhu kungenzeka kube ukwehluleka komnyango kanye nefasitela sealant!
Nakubai-silicone sealantiyinto ewusizo kuphela ekukhiqizeni amafasitela, ukubala ingxenye encane yezindleko, idlala indima ebaluleke kakhulu ekusebenzeni kwamafasitela, ikakhulukazi ekungangeni kwamanzi, ukungena komoya, ukufakwa kwe-thermal, ukwahlukanisa umsindo, njll Akufanele. kuthathwe kancane.Uma i-silicone sealant inezinkinga zekhwalithi, izodala izinkinga ezifana nokuvuza kwamanzi nokuvuza komoya, okuzothinta kakhulu ukuqina komoya kanye nokuqina kwamanzi eminyango namafasitela.
Ngakho-ke hlobo luni lwe-silicone oyisebenzisayo kumafasitela?
1. Khetha kahle imikhiqizo ehlangabezana nezindinganiso
Enqubweni yokukhetha ye-silicone sealant, ngaphezu kwezindinganiso ezihlangabezana nazo, ukunakwa kufanele kukhokhwe ezingeni elihambisanayo lokufuduka.Umthamo wokufuduka uyinkomba ebaluleke kakhulu yokukala ukunwebeka kwe-sealant.Ukuphakama komthamo wokufuduka, kuba ngcono ukunwebeka kwe-sealant.Ukuze kucutshungulwe futhi kufakwe amafasitela, imikhiqizo enekhono lokufuduka elingekho ngaphansi kwe-12.5 kufanele ikhethwe ukuze kuqinisekiswe ukuqina komoya okuhlala isikhathi eside nokuqina kwamanzi kwamafasitela.
Ngesikhathi sokufakwa kanye nokusetshenziswa kwamafasitela, umphumela wokuhlanganisa phakathi kwama-sealant ajwayelekile kanye nokhonkolo usimende uvame ukuba mubi kakhulu kunalowo onamaphrofayili e-aluminium noma ingilazi yeminyango namafasitela.Ngakho-ke, kufaneleka kakhulu ukusebenzisa isivalo esisetshenziselwa ukufakwa kwewindi e-China ukuze kuhambisane ne-JC/T 881.
Imikhiqizo enamazinga aphezulu okufuduka iyakwazi ukumelana nezinguquko ekususweni kwamalungu.Kunconywa ukukhetha imikhiqizo enamazinga aphezulu okufuduka ngangokunokwenzeka.
2. Khetha kahle imikhiqizo ye-sealant ngokusho kwesicelo
Amafasitela ohlaka olufihliwe namafeni okuvula uhlaka olufihliwe adinga i-structural sealant ukuze idlale indima yesakhiwo sokuhlanganisa.I-Silicone structural sealant kufanele isetshenziswe, futhi ububanzi bayo bokubopha kanye nobukhulu kufanele buhlangabezane nezidingo zokuklama.
Enqubweni yokufakwa komnyango namafasitela, i-sealant esetshenziselwa amalunga amatshe noma amalunga anetshe ohlangothini olulodwa kufanele kube isigxivizo esikhethekile setshe esihlangabezana ne-GB/T 23261 standard.
Ngezicabha namafasitela angashi noma iminyango namafasitela ebhilidi angaphandle adinga ubuqotho bokuvikela umlilo, kufanelekile kakhulu ukusebenzisa izinto ezivala umlilo.
Ezindaweni zokufaka izicelo ezinezidingo ezikhethekile zokumelana nesikhutha, njengamakhishi, izindlu zangasese kanye nezindawo ezimnyama nezinomswakama, ama-sealant angangenisi isikhutha kufanele asetshenziselwe ukuvala iminyango namafasitela.
3. Ungakhethi ama-silicone sealants agcwaliswe ngamafutha!
Njengamanje, kunenqwaba yeminyango egcwele uwoyela namafasitela emakethe.Le mikhiqizo igcwele inani elikhulu lamafutha amaminerali futhi inokumelana nokuguga okubi, okuzoholela ezinkingeni eziningi zekhwalithi.
Ama-silicone sealants afakwe ngamafutha amaminerali aziwa embonini ngokuthi "ama-silicone sealant enwetshwe ngamafutha".Amafutha amaminerali i-alkane petroleum distillate egcwele.Ngenxa yokuthi ukwakheka kwayo kwamangqamuzana kuhluke kakhulu kune-silicone, ayihambisani kahle nesistimu ye-silicone sealant, futhi izofuduka futhi ingene isuka ku-silicone sealant ngemva kwesikhathi esithile.Ngakho-ke, "i-sealant egcwele amafutha" ine-elasticity enhle ekuqaleni, kodwa ngemva kwesikhathi sokusetshenziswa, uwoyela wamaminerali ogcwele uyafuduka futhi ungene ku-sealant, futhi i-sealant iyancipha, iqina, iqhekeke, futhi kukhona ngisho nenkinga okungahlangani.
NgiyethembaI-Siway'sisingeniso singakulethela usizo oluthile!
