Imikhawulo ku-acid glass silicone sealant: I-acid silicone sealant izokonakalisa noma ngeke ibophe ithusi, ithusi (nezinye i-alloys eziqukethe ithusi), i-magnesium, i-zinc, insimbi efakwe ngogesi (nezinye i-alloys eziqukethe i-zinc), futhi kunconywa ukuthi kwenziwe ubumbano lube yizinto. Ungasebenzisi i-acid glass silicone sealant ku-substrate ye-iron carbide. Sebenzisa i-acid glass silicone sealant
ezintweni ezenziwe nge-methyl methacrylate (PLEXIGLAS), i-polycarbonate, i-polypropylene, i-polyethylene kanye ne-TEFLON (Teflon, i-polytetrafluoroethylene) Ngeke ikwazi ukuthola ukunamathela okuhle kanye nokuhambisana okuhle. I-silicone sealant yengilazi ye-acid ayifanele ukuxhumeka okuhamba ngaphezu kwama-25% wobubanzi bokuhlangana. I-silicone sealant yengilazi ye-acid ejwayelekile akufanele isetshenziswe engilazini yesakhiwo (ngaphandle kwe-silicone sealant yesakhiwo ye-acid). Ngaphezu kwalokho, akufanele isetshenziswe lapho kukhona ukuklwebheka kanye nokungalungi okukhulu. Sebenzisa i-silicone sealant yengilazi ye-acid. Izinga lokushisa lobuso bezinto eziyisisekelo ze-silicone acid glass silicone sealant lidlula ama-40℃ futhi alifanele ukwakhiwa. Imikhawulo ku-silicone sealant engathathi hlangothi: I-silicone sealant engathathi hlangothi ayifanele ukuhlanganiswa kwengilazi yesakhiwo; ayifanele ukwakhiwa uma izinga lokushisa lobuso be-substrate lidlula ama-50°C. Imikhawulo yokunamathela kwesakhiwo se-silicone: Ngaphandle kodonga oluphelele lwekhethini, i-silicone structural sealant ayikwazi ukufakwa endaweni yokwakha; izinga lokushisa lobuso le-silicone structural adhesive alifanele ukwakhiwa uma izinga lokushisa lobuso be-substrate lidlula ama-40°C. Izimo zokugcina kanye nesikhathi sokuphelelwa yisikhathi I-silicone sealant kufanele igcinwe ngaphansi kuka-27°C endaweni epholile, eyomile. I-silicone sealant yekhwalithi ephezulu ingaqinisekisa isikhathi esingaphezu kwezinyanga ezingu-12, kanti i-silicone sealant yeglasi ye-acid ejwayelekile ingagcinwa isikhathi esingaphezu kwezinyanga ezingu-6; i-silicone sealant engathathi hlangothi kanye neglue yokwakheka kungaqinisekisa isikhathi sokuphelelwa yisikhathi esingaphezu kwezinyanga ezingu-9. Uma ibhodlela selivuliwe, sicela ulisebenzise phakathi nesikhathi esifushane; uma i-silicone sealant ingakasetshenziswa, ibhodlela kumele livalwe. Uma ulisebenzisa futhi, umlomo webhodlela kufanele uvulwe ukuze kususwe zonke izithiyo noma kufakwe omunye umlomo webhodlela.
