Kubikwa ukuthi inhlaka ye-silicone yesakhiwo sesakhiwo ngokuvamile isetshenziswa ebangeni lokushisa elingu-5 ~ 40℃. Uma izinga lokushisa lobuso be-substrate liphezulu kakhulu (ngaphezu kuka-50℃), ukwakhiwa akukwazi ukwenziwa. Ngalesi sikhathi, ukwakhiwa kungabangela ukusabela kokwelapha kwe-sealant yesakhiwo ukuba kusheshe kakhulu, futhi izinto ezincane ezikhiqizwayo zama-molecule azinaso isikhathi sokufuduka ziphume ebusweni be-colloid, futhi zibuthane ngaphakathi kwe-colloid ukuze zakhe amabhamuza, ngaleyo ndlela zibhubhise ukubukeka kobuso be-glue joint. Uma izinga lokushisa liphansi kakhulu, ijubane lokwelapha le-sealant yesakhiwo lizoncipha, futhi inqubo yokwelapha izothatha isikhathi eside kakhulu. Phakathi nale nqubo, izinto zinganda noma zinciphe ngenxa yokwehluka kwezinga lokushisa, futhi ukuphuma kwe-sealant kungaphambukisa ukubukeka.
Uma izinga lokushisa lingaphansi kuka-4 ℃, ubuso be-substrate kulula ukubuqinisa, ukubuqandisa kanye neqhwa, okuletha izingozi ezinkulu ezifihliwe ekubopheni. Kodwa-ke, uma uqaphela ukuhlanza amazolo, i-icing, iqhwa futhi unolwazi ngeminye imininingwane, ukwakha izinamathiselo zesakhiwo kungasetshenziswa futhi ekwakheni okujwayelekile kokunamathelisa.
Ukuhlanzwa kwezindawo zezinto kubalulekile ekuvaleni nasekubopheni. Ngaphambi kokubopha, i-substrate kumele ihlanzwe nge-solvent. Kodwa-ke, ukuguquguquka kwe-ejenti yokuhlanza nokulinganisa kuzosusa amanzi amaningi, okuzokwenza izinga lokushisa lobuso be-substrate libe ngaphansi kunezinga lokushisa lobuso be-dry ring culture. Endaweni enezinga lokushisa eliphansi lokomisa, kulula ukudlulisa amanzi azungezile aye ku-substrate ngamunye ngamunye. Kunzima kwabanye abasebenzi ukuqaphela ubuso bezinto. Ngokwesimo esijwayelekile, kulula ukubangela ukwehluleka kokubopha kanye nokuhlukaniswa kwe-sealant kanye ne-substrate. Indlela yokugwema izimo ezifanayo ukuhlanza i-substrate ngendwangu eyomile ngesikhathi ngemuva kokuhlanza i-substrate nge-solvent. Amanzi ahlanganisiwe azosulwa futhi ngendwangu, futhi kungcono ukufaka i-glue ngesikhathi.
Uma ukwanda kokushisa kanye nokufuduka kokubanda kwezinto ngenxa yokushisa kukhulu kakhulu, akufaneleki ukwakhiwa. Lapho kwakhiwa i-silicone sealant esakhiweni ihamba ohlangothini olulodwa ngemva kokuqina, ingabangela ukuthi i-sealant ihlale icindezelekile noma icindezelwe, okungabangela ukuthi i-sealant ihambe ohlangothini olulodwa ngemva kokuqina.
