Imikhawulo ku-acid glass silicone sealant : I-Acid silicone sealant izogqwala noma ayikwazi ukubopha ithusi, ithusi (kanye nezinye izinhlaka ezinethusi), i-magnesium, i-zinc, insimbi efakwe ugesi (kanye namanye ama-alloys aqukethe i-zinc), futhi kuyanconywa ukuthi yenziwe. zibe izihloko Futhi 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 ne-TEFLON (i-Teflon, i-polytetrafluoroethylene) Ngeke ikwazi ukuthola ukunamathela okuhle nokuhambisana okuhle. I-Acid glass silicone sealant ayifanele ukuxhumana okuhambisa ngaphezu kuka-25% wobubanzi obuhlangene. I-Ordinary acid glass silicone sealant akufanele isetshenziswe engilazini yesakhiwo (ngaphandle kwe-acid structural silicone sealant). Ngaphezu kwalokho, akufanele isetshenziswe lapho kukhona imihuzuko kanye nokubi kakhulu. Sebenzisa i-acid glass silicone sealant. Izinga lokushisa elingaphezulu lesisekelo se-silicone ingilazi ye-silicone sealant idlula 40 ℃ futhi ayifanele ukwakhiwa. Imikhawulo ku-silicone sealant engathathi hlangothi: I-Silicone sealant engathathi hlangothi ayifanele ukuhlanganiswa kwengilazi yesakhiwo; ayifanele ukwakhiwa uma izinga lokushisa le-substrate lingaphezu kuka-50°C. Imikhawulo yokunamathela yesakhiwo se-silicone: Ngaphandle kodonga olugcwele lwamakhethini, i-silicone structural sealant ayikwazi ukujova endaweni yokwakha; izinga lokushisa elingaphezulu le-adhesive yesakhiwo se-silicone alifanele ukwakhiwa uma izinga lokushisa elingaphansi kwe-substrate lingaphezu kuka-40°C. Izimo zesitoreji nempilo yeshelufu I-silicone sealant kufanele igcinwe ngaphansi kuka-27°C endaweni epholile neyomile. Ikhwalithi enhle ye-acid glass silicone sealant ingaqinisekisa ngaphezu kwezinyanga ezingu-12, futhi i-asidi ejwayelekile yengilazi ye-silicone sealant ingagcinwa isikhathi esingaphezu kwezinyanga ezingu-6; I-silicone sealant engathathi hlangothi kanye ne-structural glue ingaqinisekisa impilo yeshalofu yezinyanga ezingaphezu kweziyi-9. Uma ibhodlela selivuliwe, sicela ulisebenzise ngesikhathi esifushane; uma i-silicone sealant ingasetshenzisiwe, ibhodlela kufanele livalwe. Uma uyisebenzisa futhi, umlomo webhodlela kufanele ukhululwe ukuze kususwe konke okuvalekile noma esikhundleni somlomo webhodlela.
