Kubikwa ukuthi isakhiwo sesakhiwo se-silicone adhesive ngokuvamile sisetshenziswa ebangeni lokushisa le-5 ~ 40 ℃. Lapho izinga lokushisa elingaphezulu le-substrate liphezulu kakhulu (ngenhla kwe-50 ℃), ukwakhiwa akunakwenziwa. Ngalesi sikhathi, ukwakhiwa kungadala ukusabela kokwelapha kwe-sealant yesakhiwo ukuba kusheshe kakhulu, futhi izinto ezincane ezikhiqizwayo azinaso isikhathi sokuhamba ngaphandle kwe-colloid, bese ziqoqa ngaphakathi kwe-bubble, ngaleyo ndlela zichithe ukubukeka komhlaba kwe-glue ngokuhlangene. Uma izinga lokushisa liphansi kakhulu, ijubane lokuphulukisa lesakhiwo se-sealant lizoncipha, futhi inqubo yokwelapha izokhula isikhathi eside kakhulu. Ngale nqubo, lokho okuqukethwe kungakhula noma inkontileka ngenxa yokwehluka kokushisa, nokukhishwa kwe-sealant kungahlanekezela ukubukeka.
Lapho amazinga okushisa ephansi kune-4 ℃, ingaphezulu le-substrate kulula ukuyisebenzisa, iqhwa futhi iqhwa, eliletha izingozi ezinkulu ezifihliwe esibonelweni. Kodwa-ke, uma unakekela amazolo ehlanzekile, i-icing, isithwathwa kanye nemininingwane ethile, izinhloso zokwakha ezakhiwe nazo zingasetshenziselwa ukwakhiwa okujwayelekile okunamakhandlela.
Ukuhlanza izindawo ezibonakalayo kubalulekile ukubekwa uphawu nokubopha. Ngaphambi kokubhidlizwa, i-substrate kumele ihlanzwe nge-solvent. Kodwa-ke, ukuguquguquka kwe-ejenti yokuhlanza nokudala kuzosusa amanzi amaningi, azokwenza izinga lokushisa elingaphezulu kwe-substrate liphansi kunamazinga okushisa aphezulu. Emvelweni enamazinga okushisa aphansi wokumisa, kulula ukudlulisa amanzi azungezile engxenyeni engaphansi koyedwa kunzima kwabanye abasebenzi ukuze babone indawo yalokho. Ngokwesimo esijwayelekile, kulula ukudala ukwehluleka kwe-bonding kanye nokwehlukaniswa kwe-sealant kanye ne-substrate. Indlela yokugwema izimo ezifanayo ukuhlanza i-substrate ngendwangu eyomile ngesikhathi ngemuva kokuhlanza i-substrate. Amanzi ahlanganisiwe azophinde asulwe ngowomile yi-rag, futhi kungcono ukufaka isicelo se-glue ngesikhathi.
Lapho ukwanda okushisayo kanye nokukhishwa okubandayo kokuthengiswa kwezinto ezibonakalayo ngenxa yokushisa kukhulu kakhulu, akufaneleki ukwakhiwa. Lapho kwakhiwa i-Silicone Sealant ehlelekile ngemuva kokuphulukisa, kungadala ukuthi i-sealant ihlale engxabanweni noma ekucindezelweni, okungadala ukuthi i-sealant idluliselwe endaweni eyodwa ngemuva kokuphulukisa.
