Njengoba izinga lokushisa liqhubeka likhuphuka, umswakama emoyeni uyanda, okuzoba nomthelela ekuqineni kwemikhiqizo ye-silicone sealant. Ngenxa yokuthi ukuqina kwe-sealant kudinga ukuthembela kumswakama osemoyeni, ukushintsha kwezinga lokushisa kanye nomswakama endaweni ezungezile kuzoba nomthelela omkhulu ekusetshenzisweni kwemikhiqizo ye-silicone sealant. Ngezinye izikhathi, kuzoba namabhamuza amakhulu namancane ejoyintini leglue. Ngemva kokusika, ingaphakathi liba yimbobo. Amabhamuza ase-sealant azonciphisa i-viscosity yesakhiwo se-sealant futhi anciphise kakhulu umphumela wokuvala.
Uchungechunge lokwakhiwa kwesivalo sokwakha (isivalo sokwakha sodonga lwekhethini, isivalo sesibili sokwakha sembobo, njll.):
1. Ukuhlanza i-substrate
Ehlobo, izinga lokushisa liphezulu futhi isinyibilikisi sokuhlanza siyashintshashintsha, ngakho-ke kufanele kuqashelwe umthelela emphumeleni wokuhlanza.
2. Faka uketshezi lwe-primer
Ehlobo, izinga lokushisa kanye nomswakama kuphezulu, futhi i-primer ifakwa kalula emanzini futhi ilahlekelwa umsebenzi wayo emoyeni. Kufanele kuqashelwe ukufaka i-glue ngokushesha okukhulu ngemva kokusebenzisa i-primer. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi lapho uthatha i-primer, inani lezikhathi nesikhathi i-primer evezwa ngaso emoyeni kufanele lincishiswe ngangokunokwenzeka, futhi kungcono ukusebenzisa amabhodlela amancane okushintshana ukuze kukhishwe.
3. Umjovo
Ngemva kokufakwa kweglue, i-sealant engamelani nesimo sezulu ayikwazi ukufakwa ngaphandle ngokushesha, ngaphandle kwalokho, ijubane lokuphola kwe-structural sealant lizoncishiswa kakhulu.
4. Ukusika
Ukusika kufanele kwenziwe ngokushesha ngemva kokuqedwa kokujova ngeglue. Ukusika kwenza kube lula ukuxhumana phakathi kwe-sealant nohlangothi lwe-interface. 5. Amarekhodi kanye nokuhlonza Ngemva kokuba izinqubo ezingenhla seziqediwe, bhala phansi bese ulebula ngesikhathi. 6. Ukugcinwa Isici esisodwa kumele silungiswe isikhathi esanele ngaphansi kwezimo ezingaguquki nezingenakucindezeleka ukuqinisekisa ukuthi i-structural sealant ikhiqiza ukunamathela okwanele.
