I-Silicone Sealant iyindlela ebalulekile yokunamathela, ikakhulukazi esetshenziselwa ukubopha ingilazi ehlukahlukene namanye ama-substrates. Kusetshenziswa kabanzi empilweni yomndeni, futhi kunezinhlobo eziningi ze-silicone sealants emakethe, futhi amandla ebhondi e-silicone sealants ngokuvamile aboniswa. Ngakho-ke, kanjani ukusebenzisa i-silicone sealant? Kuthatha isikhathi esingakanani ukuthi i-silicone sealant yelaphe?
Silicone Sealant Ukusebenzisa Izinyathelo
1.Remove umswakama, grease, uthuli nokunye ukungcoliswa kwezinto ebusweni bezinto. Lapho kufaneleka, sebenzisa i-solvent (efana ne-xylent, i-butanone) ukuhlanza ingaphezulu, bese usebenzisa i-rag ehlanzekile ukuze usule zonke izinsalela ukuyenza ihlanzeke ngokuphelele futhi yome.
2.Cumba ingaphezulu eduze kwesixhumi ngetheyipu yepulasitiki. Ukuqinisekisa ukuthi umugqa wokufaka uphawu uphelele futhi ucocekile.
3.Cupha ukubekwa uphawu kwe-hose uphawu bese ufaka ipayipi elikhonjisiwe le-nozzle. Bese kuthi ngokuya ngosayizi we-caulking, kusikwa ngo-45 ° angle.
I-4.Phisa isibhamu se-glue bese ucindezela okuqukethwe kwe-glue kanye negebe elise-angle elingu-45 ° ukuqinisekisa ukuthi izinto ze-glue zizoxhumana kakhulu nezezinto zesisekelo. Lapho ububanzi bomthungo bukhulu kune-15 mm, i-gluing ephindaphindwayo iyadingeka. Ngemuva kokugcotshwa kwe-gluing, nquma indawo ngommese ukuze ususe i-glue ngokweqile, bese uyikhipha ethepheni. Uma kukhona amabala, ubasuse ngendwangu emanzi.
I-5.sealant ekushiseni kwegumbi ngemuva kwemizuzu eyi-10 yokuvuselelwa kobuntu, ukuvuvukala okuphelele kuthatha amahora angama-24 noma ngaphezulu, ngokuya ngobukhulu be-coating kanye nokushisa kanye nomswakama wemvelo.
I-Silicone Sealant Cughter Time
I-Silicone Sealant Stinging Time nesikhathi sokwelapha:
Inqubo ye-Silicone Sealant yelapha ithuthukiswa ukusuka phezulu kuya ngaphakathi, izici ezihlukile ze-sealant surface isikhathi isikhathi somile kanye nesikhathi sokwelashwa azifani, ngakho-ke uma ufuna ukulungisa ingaphezulu lenziwe ngaphambi kokuba kube khona indawo ebekwe phansi. Phakathi kwazo, i-glue ye-acid kanye ne-glue engathathi hlangothi kufanele ibe ngaphansi kwemizuzu engu-5 ~ 10, kanye nama-glue angathathi hlangothi ngokuvamile kufanele kube ngemizuzu engama-30. Uma iphepha lokuhlukanisa imibala lisetshenziselwa ukumboza indawo ethile, ngemuva kokusebenzisa i-glue, kufanele isuswe ngaphambi kokuba isikhumba sakhiwe.
Isikhathi sokupheqa se-silicone sealant (ekushiseni kwamakamelo okungu-20 ° nomswakama ka-40%) kuyanda ngokwanda kokuqina kobugqi. Isibonelo, i-abitone sealant eyi-12mm eqinile ingathatha izinsuku ezingama-3-4 ukusetha, kepha kungakapheli amahora angama-24, ungqimba lwangaphandle lwe-3mm lwelapha. Uma indawo lapho kusetshenziswa khona i-sealant ngokwengxenye noma kuvalwe ngokuphelele, isikhathi sokuphequlula sinqunywa ngokuqina kophawu. Ezimweni ezahlukahlukene zokubopha, kufaka phakathi izimo zomoya, umphumela wokubopha kufanele uhlolwe ngokugcwele ngaphambi kokuba kusetshenziswe imishini eboshwe. Ukulapha kuzonciphisa amazinga okushisa aphansi (ngaphansi kuka-5 °) kanye nomswakama (ngaphansi kwama-40%).
