Kwiingcango kunye neefestile, ii-sealants zisetyenziselwa ukutywinwa ngokudibeneyo kweefestile zefestile kunye neglasi, kunye nokutywinwa ngokudibeneyo kweefestile zefestile kunye neendonga zangaphakathi nangaphandle.Iingxaki ekusetyenzisweni kwe-sealant kwiingcango kunye neefestile ziya kukhokelela ekungaphumeleli kweminyango kunye nezitywina zefestile, okubangelwa ukuvuza kwamanzi, ukuvuza komoya kunye nezinye iingxaki, eziya kuchaphazela ngokunzulu umgangatho jikelele weengcango kunye neefestile. ukusetyenziswa kwe-sealant kwiingcango kunye neefestile, kwaye unikeze izisombululo ngokuhlalutya izizathu zokunceda abasebenzisi basebenzise kakuhle i-sealant.Okokuqala, ndiza kwazisa ezona ngxaki zixhaphakileyo: ukungahambelani, ukudityaniswa kakubi, kunye neengxaki zokugcina.
① Ayihambelani
Ezinye izinto zokuncedisa ezisetyenziselwa ukudibanisa umnyango kunye nefestile, njengezinto zerabha (iipadi zerabha, imichilo yerabha, njl. njl.), ngokuqhelekileyo banoqhagamshelwano olusondeleyo kunye ne-sealant.Nangona kunjalo, ezinye iimveliso zerabha zingongeza i-oyile yerabha okanye ezinye izinto ezincinci zemolekyuli ezingahambelaniyo nenkqubo yokutywina ngenxa yokunciphisa iindleko zomenzi okanye ezinye izinto eziqwalaselwayo.Xa iimveliso zerabha ezinjalo zidibene ne-silicone sealant, ioli yerabha okanye ezinye izinto ezincinci ze-molecular ziya kufudukela kwi-sealant, kwaye zifudukele kumphezulu we-sealant.Ngexesha lokusetyenziswa, phantsi kwesenzo sokukhanya kwelanga kunye nemitha ye-ultraviolet, i-sealant ingaba phuzi.Lo mcimbi ubonakala ngakumbi kucango kunye neefestile ezincamathelayo ezinemibala ekhaphukhaphu.
Ngoko ke, sincoma ukuba ngaphambi kokubaisitywiniisetyenzisiwe, uvavanyo lokuhambelana kwe-sealant kunye nezinto ezinxibelelana nazo kufuneka zenziwe ngokwendlela yokuvavanya ukuhambelana kwiSihlomelo A se-GB 16776 ukumisela ukuhambelana phakathi kwe-sealant kunye ne-substrate, kwaye ngokwendlela yokuvavanya ukuhambelana.Ulwakhiwo lwenziwa njengoko kufunwa ziziphumo zovavanyo.
② Unxulumano olubi
Ekusetyenzisweni komnyango kunye nefestilei-silicone sealant,i-substrates enokuthi idibane yiglasi, i-aluminiyam, i-cement mortar, i-cement tile, ipeyinti yodonga, njl.Ukuba i-adhesion ayiqinisekiswanga ngaphambi kokwakhiwa, kunokubangela ukubambelela kakubi kocango kunye nefestile ye-silicone sealant.Xa i-silicone sealant isetyenziselwa ukudibanisa phakathi kweengcango kunye neefestile kunye nodonga lwangaphandle lodaka lwesamente, ukuba uthuli kunye nesanti umphezulu wodaka lwesamente eludongeni lwangaphandle alucocwanga, kunokubakho into eyenzeka ngokungadibanisi emva kokuba i-sealant iphiliswe.
Ngoko ke, kwinkqubo yokwenyani yokusebenzisa i-silicone sealant, kuyimfuneko ukunikela ingqalelo kwi-pretreatment yobuso be-substrate ukuba ibambelele, kwaye usebenzise iindlela ezifanelekileyo zokususa ioli, uthuli, isanti, kulula ukuwa kwiileyile ezikhululekile.
③ Iingxaki zokugcina isitywina
IsitywiniIimveliso zezemveliso yeekhemikhali kwaye zinexesha elithile lokugcina, ngoko ke kufuneka zisetyenziswe ngaphakathi kwexesha lokugcina.Ukuba i-sealant igqithile kubomi baso beshelufu, kunokwenzeka ukuba izinga lokunyanga liyacotha kakhulu, linganyangeki kakuhle okanye linganyangeki.
Ngokweemfuno zeemeko zokugcina kwimigangatho echaphazelekayo yezitywini, ixesha lokugcinwa kwegama lee-sealants lingaphantsi kwe-27 ° C kwaye phantsi kweemeko ezipholileyo, ezomileyo kunye nomoya.Ukuba indawo yokugcina kwindawo yokusetyenziswa ngokwenene ayikwazi ukuhlangabezana neemeko ezichazwe kumgangatho, ezifana neqondo lokushisa eliphezulu kakhulu, ixesha lokugcinwa kwe-sealant linokufinyezwa.Nokuba i-sealant ayidluli ixesha lokugcinwa kwegama phantsi kwalo mqathango, isenzeko sonyango olucothayo luya kwenzeka.
