Kubikwa ukuthi ingcina ye-silicone yesakhiwo ngokuvamile isetshenziswa ebangeni lokushisa elingu-5 ~ 40 ℃. Lapho izinga lokushisa elingaphezulu le-substrate liphezulu kakhulu (ngaphezu kuka-50 ℃), ukwakhiwa ngeke kwenziwe. Ngalesi sikhathi, ukwakhiwa kungabangela ukusabela kokuphulukisa kwe-sealant yokwakha ukuthi kusheshe kakhulu, futhi izinto ezincane ezikhiqiziwe ze-molecular azinaso isikhathi sokufuduka ngaphandle kwe-colloid, futhi ziqoqe ngaphakathi kwe-colloid ukuze zenze ama-bubbles, ngaleyo ndlela zibhubhise. ukubukeka okungaphezulu kokuhlangana kweglue. Uma izinga lokushisa liphansi kakhulu, ijubane lokuphulukisa le-sealant yokwakha lizohamba kancane, futhi inqubo yokwelapha izokwelulwa ngokuphawulekayo. Phakathi nale nqubo, impahla ingase ikhule noma inkontileka ngenxa yokuhluka kwezinga lokushisa, futhi i-extrusion ye-sealant ingahlanekezela ukubukeka.
Lapho izinga lokushisa lingaphansi kuka-4 ℃, ingaphezulu le-substrate kulula ukujiya, libe yiqhwa kanye nesithwathwa, okuletha izingozi ezinkulu ezifihliwe ekubopheni. Kodwa-ke, uma unakekela ukuhlanza amazolo, uqweqwe lweqhwa, isithwathwa kanye nemininingwane ethile, izinamathiselo zesakhiwo nazo zingasetshenziselwa ukwakhiwa kwe-gluing evamile.
Ukuhlanzwa kwezinto ezibonakalayo kubalulekile ekuvaleni nasekubopheni. Ngaphambi kokubopha, i-substrate kufanele ihlanzwe nge-solvent. Kodwa-ke, ukuvuthwa kwe-ejenti yokuhlanza nokubeka izinga kuzosusa amanzi amaningi, okuzokwenza izinga lokushisa elingaphezulu le-substrate libe ngaphansi kwezinga lokushisa elingaphezulu kwesiko lendandatho elomile. Endaweni enezinga lokushisa eliphansi lokumisa, kulula ukudlulisa amanzi azungezile ku-substrate ngayinye Kunzima kwabanye abasebenzi ukuthi baqaphele ubuso bezinto. Ngokwesimo esivamile, kulula ukubangela ukuhluleka kokubopha nokuhlukaniswa kwe-sealant ne-substrate. Indlela yokugwema izimo ezifanayo ukuhlanza i-substrate ngendwangu eyomile ngesikhathi ngemuva kokuhlanza i-substrate nge-solvent. Amanzi ahlanganisiwe nawo azosulwa ome nge-rag, futhi kungcono ukusebenzisa i-glue ngesikhathi.
Lapho ukunwetshwa okushisayo nokufinyezwa okubandayo kwento ngenxa yezinga lokushisa kukukhulu kakhulu, akufanelekile ukwakhiwa. Lapho ukwakha i-silicone sealant yesakhiwo ihamba ohlangothini olulodwa ngemva kokuphulukiswa, kungabangela ukuthi i-sealant ihlale iqinile noma icindezelekile, okungabangela ukuthi i-sealant ihambe ohlangothini olulodwa ngemva kokuphulukiswa.
