Ezicabheni nasemafasiteleni, ama-sealants asetshenziselwa ukufakwa uphawu ngokuhlanganyela kwamafreyimu efasitela nengilazi, nokufaka uphawu ngokuhlanganyela kwamafreyimu amafasitela kanye nezindonga zangaphakathi nezangaphandle.Izinkinga ekusetshenzisweni kwe-sealant ezicabheni namafasitela zizoholela ekuhlulekeni kwezivalo zeminyango namafasitela, okuholela ekuvuzeni kwamanzi, ukuvuza komoya kanye nezinye izinkinga, okuzothinta kakhulu ikhwalithi yonke yeminyango namafasitela.Yethula izinkinga ezivamile ku ukusetshenziswa kwe-sealant yezicabha namafasitela, futhi unikeze izixazululo ngokuhlaziya izizathu zokusiza abasebenzisi ukuthi basebenzise kahle i-sealant.Okokuqala, ngizokwethula izinkinga ezivame kakhulu: ukungahambisani, ukuhlanganiswa okungalungile, nezinkinga zokugcina.
① Akuhambisani
Ezinye izinto ezisetshenziswa ekuhlanganiseni umnyango namafasitela, njengezinto zenjoloba (amaphedi enjoloba, amapheshana enjoloba, njll.), ngokuvamile zinokuxhumana okuseduze ne-sealant.Kodwa-ke, eminye imikhiqizo yenjoloba ingase yengeze amafutha enjoloba noma ezinye izinto ezincane zamangqamuzana ezingahambisani nesistimu yokuvala uphawu ngenxa yokwehliswa kwezindleko zomenzi noma okunye ukucatshangelwa.Lapho imikhiqizo yenjoloba enjalo ithintana ne-silicone sealant, uwoyela wenjoloba noma ezinye izinto ezincane zamangqamuzana azothuthela ku-sealant, futhi afudukele ngisho nangaphezulu kwe-sealant.Ngesikhathi sokusetshenziswa, ngaphansi kwesenzo sokukhanya kwelanga nemisebe ye-ultraviolet, i-sealant ingase ibe phuzi.Lesi simo sisobala kakhulu ezinamathiselwe ezicabheni nasezifasiteleni ezinemibala ekhanyayo.
Ngakho-ke, sincoma ukuthi ngaphambi kokuthengai-sealantisetshenziswa, ukuhlolwa kokuhambisana kwe-sealant nezinto ezithintana nayo kufanele kwenziwe ngokwendlela yokuhlola ukuhambisana ku-Appendix A ye-GB 16776 ukuze kutholwe ukuhambisana phakathi kwe-sealant ne-substrate, futhi ngokuya kwendlela yokuhlola ukuhambisana.Ukwakhiwa kwenziwa njengoba kudingwa yimiphumela yokuhlolwa.
② Ukungahlangani kahle
Ekusetshenzisweni komnyango newindii-silicone sealant,ama-substrates angase ahlangane ingilazi, i-aluminium, udaka lukasimende, ithayela le-ceramic, upende odongeni, njll. Kungase kube nowoyela, uthuli noma ezinye izinto eziyinsalela ebusweni balezi zinto.Uma ukunamathela kungaqinisekisiwe ngaphambi kokwakhiwa, kungase kubangele ukunamathela okungalungile komnyango kanye newindi le-silicone sealant. ubuso bodaka lukasimende odongeni lwangaphandle aluhlanzwa, kungase kube khona into engekho yokubopha ngemuva kokuthi i-sealant ilashwe.
Ngakho-ke, enqubweni yangempela yokusebenzisa i-silicone sealant, kubalulekile ukunaka ukulungiswa kwe-surface ye-substrate okufanele ilandelwe, futhi usebenzise izindlela ezifanele zokususa uwoyela, uthuli, isihlabathi, ukuwela kalula izingqimba ezixekethile.
③ Izinkinga zesitoreji se-sealant
I-Sealantimikhiqizo ingeyemikhiqizo yamakhemikhali futhi inesikhathi esithile sokuyigcina, ngakho kudingeka ukuthi isetshenziswe phakathi nesikhathi sokuyigcina.Uma i-sealant yeqe impilo yayo yeshalofu, kungenzeka ukuthi izinga lokwelapha lizohamba kancane kakhulu, lingelapheki kahle noma lingelapheki.
Ngokuvumelana nezidingo zezimo zokulondoloza emazingeni afanele ama-sealant, isikhathi sokugcina sezinto ezifakwa uphawu singaphansi kuka-27°C futhi ngaphansi kwezimo ezipholile, ezomile nezinomoya.Uma indawo yesitoreji ekusetshenzisweni kwangempela ingakwazi ukuhlangabezana nezimo ezishiwo ezingeni, njengezinga lokushisa le-ambient liphezulu kakhulu, isikhathi sokugcina se-sealant singancishiswa.Ngisho noma i-sealant ingeqi isikhathi sokugcina ngaphansi kwalesi simo, into yokwelapha kancane izokwenzeka.
