Ngokukhuphuka okuqhubekayo kwezinga lokushisa, umswakama emoyeni uyanda, okuzoba nomthelela ekwelapheni kwemikhiqizo ye-silicone sealant.Ngenxa yokuthi ukuphulukiswa kwe-sealant kudinga ukuthembela kumswakama emoyeni, ukushintsha kwezinga lokushisa nomswakama endaweni kuzoba nomthelela omkhulu ekusetshenzisweni kwemikhiqizo ye-silicone sealant.Ngezinye izikhathi, kuzoba namabhamuza amakhulu namancane ekuhlanganyeleni kweglue.Ngemva kokusika, ingaphakathi lingenalutho.Ama-bubbles ku-sealant azonciphisa i-viscosity yesakhiwo se-sealant futhi anciphise kakhulu umphumela wokuvala.
Ukulandelana kokwakhiwa kwe-structural sealant (i-structural sealant yodonga lwamakhethini, i-sealant structural sealant yokungenalutho, njll.):
1. Ukuhlanza i-substrate
Ehlobo, izinga lokushisa liphezulu futhi i-solvent yokuhlanza iyaguquguquka, ngakho-ke kufanele kuqashelwe umthelela wokuhlanza.
2. Faka i-primer liquid
Ehlobo, izinga lokushisa kanye ne-humidityare high, futhi i-primer i-hydrolyzed kalula futhi ilahlekelwa umsebenzi wayo emoyeni.Ukunakekelwa kufanele kuthathwe ukujova i-glue ngokushesha ngangokunokwenzeka ngemva kokufaka i-primer .Ngasikhathi sinye, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inani lezikhathi kanye nesikhathi lapho i-primer ivezwa emoyeni kufanele kuncishiswe ngangokunokwenzeka. , futhi kungcono ukusebenzisa amabhodlela amancane okubuyisela ukuze ukhiphe.
3. Umjovo
Ngemuva kokuthi i-glue ijovwe, i-sealant ephikisana nesimo sezulu ayikwazi ukusetshenziswa ngaphandle ngokushesha, ngaphandle kwalokho, isivinini sokuphulukisa se-sealant yesakhiwo sizoncishiswa kakhulu.
4. Ukunquma
Ukunquma kufanele kwenziwe ngokushesha ngemva kokuba umjovo weglue usuqediwe.Ukunquma kusiza ukuxhumana phakathi kwe-sealant kanye nohlangothi lwesixhumi esibonakalayo.5. Amarekhodi kanye nokuhlonza Ngemva kokuba lezi zinqubo ezingenhla seziqediwe, rekhoda bese ulebula ngesikhathi.6. Ukunakekela Isici esisodwa kufanele selashwe isikhathi esanele ngaphansi kwezimo ezimile nezingagxilile ukuze kuqinisekiswe ukuthi i-sealant yesakhiwo ikhiqiza ukunamathela okwanele.
