Eminyango nasemafasiteleni, ama-sealant asetshenziswa kakhulu ekuvaleni amafreyimu efasitela nengilazi ngokuhlangana, kanye nokuvala amafreyimu efasitela ngokuhlangana nezindonga zangaphakathi nezangaphandle. Izinkinga ekusetshenzisweni kwe-sealant yeminyango namafasitela zizoholela ekuhlulekeni kwezimpawu zomnyango namafasitela, okuholela ekuvuzeni kwamanzi, ukuvuza komoya nezinye izinkinga, okuzothinta kakhulu ikhwalithi iyonke yeminyango namafasitela. Ngethula ezinye zezinkinga ezivamile ekusetshenzisweni kwe-sealant yeminyango namafasitela, futhi unikeze izixazululo ngokuhlaziya izizathu zokusiza abasebenzisi ukuthi basebenzise kahle i-sealant. Okokuqala, ngizokwethula izinkinga ezivame kakhulu: ukungahambelani, ukubopha okungekuhle, nezinkinga zokugcina.
① Akuhambelani
Ezinye izinto ezisetshenziswa ekuhlanganisweni kweminyango namafasitela, njengezinto zerabha (amaphedi erabha, imichilo yerabha, njll.), zivame ukuba nokuxhumana okuseduze ne-sealant. Kodwa-ke, eminye imikhiqizo yerabha ingase ingeze uwoyela werabha noma ezinye izinto ezincane zama-molecule ezingahambisani nohlelo lwe-sealant ngenxa yokunciphisa izindleko zomenzi noma ezinye izinto ezicatshangelwayo. Lapho imikhiqizo enjalo yerabha ithintana ne-silicone sealant, uwoyela werabha noma ezinye izinto ezincane zama-molecule zizothuthela ku-sealant, futhi zize zithuthele ebusweni be-sealant. Ngesikhathi sokusetshenziswa, ngaphansi kwesenzo sokukhanya kwelanga nemisebe ye-ultraviolet, i-sealant ingaba phuzi. Lesi simo sibonakala kakhulu ezinamathiselweni zomnyango namafasitela ezinemibala ekhanyayo.
Ngakho-ke, sincoma ukuthi ngaphambi kokuthiisivaliUma kusetshenziswa, ukuhlolwa kokuhambisana kwe-sealant kanye nezinto ezixhumana nayo kufanele kwenziwe ngokwendlela yokuhlola ukuhambisana ku-Appendix A ye-GB 16776 ukuze kutholakale ukuhambisana phakathi kwe-sealant kanye ne-substrate, kanye nangokuya ngendlela yokuhlola ukuhambisana. Ukwakhiwa kwenziwa njengoba kudingeka ngemiphumela yokuhlolwa.
② Ubudlelwano obubi
Ekusetshenzisweni komnyango nefasitelai-silicone sealant,Izinto ezingasetshenziswa zingathintana nengilazi, i-aluminium, udaka lukasimende, ithayela le-ceramic, upende wodonga, njll. Kungase kube namafutha, uthuli noma ezinye izinto ezisele ebusweni balezi zinto. Uma ukunamathela kungaqinisekiswanga ngaphambi kokwakhiwa, kungabangela ukunamathela okubi kwe-silicone sealant yomnyango nefasitela. Lapho i-silicone sealant isetshenziswa endaweni ephakathi kweminyango namafasitela nodonga lwangaphandle lwe-samente mortar, uma uthuli nesihlabathi ebusweni be-samente mortar yodonga lwangaphandle kungahlanzwa, kungase kube nesimo sokungaxhumani ngemva kokuba i-sealant ilashiwe.
Ngakho-ke, enkambisweni yangempela yokusebenzisa i-silicone sealant, kubalulekile ukunaka ukwelashwa kwangaphambili kobuso be-substrate okufanele inamathele, bese usebenzisa izindlela ezifanele zokususa uwoyela, uthuli, isihlabathi, okulula ukuwa ezingqimbeni ezikhululekile.
③ Izinkinga zokugcina isivalo
IsivaliImikhiqizo ingeyamakhemikhali futhi inesikhathi esithile sokugcina, ngakho-ke kudingeka ukuthi isetshenziswe phakathi nesikhathi sokugcina. Uma i-sealant idlule isikhathi sayo sokuphelelwa yisikhathi, kungenzeka ukuthi izinga lokuphulukiswa lizohamba kancane kakhulu, linganyangeki kahle noma linganyangeki.
Ngokwezidingo zezimo zokugcina ezindinganisweni ezifanele zama-sealant, isikhathi sokugcina sama-sealant singaphansi kwama-27°C futhi ngaphansi kwezimo ezipholile, ezomile nezinomoya. Uma indawo yokugcina esetshenziswayo ingakwazi ukuhlangabezana nezimo ezichazwe endinganisweni, njengokuthi izinga lokushisa elizungezile liphezulu kakhulu, isikhathi sokugcina se-sealant singafinyezwa. Ngisho noma i-sealant ingadluli isikhathi sokugcina esilinganiselwe ngaphansi kwalesi simo, kuzokwenzeka isimo sokuphola kancane.
