Izithintelo ekusebenziseni iglasi ye-silicone sealant

Izithintelo kwiglasi ye-asilic sealant sealant: I-asidi ye-silicone sealant iya kugqwala okanye ayinakukwazi ukubopha ubhedu, ubhedu (kunye nezinye i-alloys ezinobhedu), i-magnesium, i-zinc, i-electroplated metal (kunye nezinye i-alloys ezinezinc), kwaye kuyacetyiswa ukuba yenziwe. kumanqaku Kwaye ungasebenzisi i-asilic glass silicone sealant kwi-iron carbide substrate. Sebenzisa iglasi ye-asilic silicone sealant

kwizinto ezenziwe nge-methyl methacrylate (PLEXIGLAS), i-polycarbonate, i-polypropylene, i-polyethylene kunye ne-TEFLON (i-Teflon, i-polytetrafluoroethylene) ayiyi kukwazi ukufumana ukubambelela kakuhle kunye nokuhambelana kakuhle. I-Acid glass silicone sealant ayifanelekanga ukudibanisa okuhamba ngaphezu kwe-25% yobubanzi obuhlangeneyo. I-asidi eqhelekileyo yeglasi i-silicone sealant ayifanele isetyenziswe kwiglasi yesakhiwo (ngaphandle kwe-asilic structural silicone sealant). Ukongezelela, akufanele isetyenziswe apho kukho i-abrasion kunye nokungalunganga okukhulu. Sebenzisa iglasi ye-asilic silicone sealant. Ubushushu bomgangatho wesiseko se-silicone yeglasi ye-silicone sealant idlula i-40 ℃ kwaye ayifanelekanga ukwakhiwa. Izithintelo kwi-silicone sealant engathathi hlangothi: I-silicone engathathi hlangothi i-sealant ayifanelekanga kwindibano yeglasi yesakhiwo; ayifanelekanga ukwakhiwa ukuba ubushushu be-substrate bungaphezu kwama-50°C. Izithintelo zokubambelela kwisakhiwo se-silicone: Ngaphandle kodonga olupheleleyo lwamakhethini, i-silicone structural sealant ayikwazi ukujova kwindawo yokwakha; ubushushu bomphezulu we-adhesive ye-silicone yesakhiwo ayifanelekanga ukwakhiwa ukuba i-substrate yeqondo lokushisa lidlula i-40 ° C. Iimeko zokugcina kunye nobomi beshelufu I-silicone sealant kufuneka igcinwe ngaphantsi kwe-27 ° C kwindawo epholileyo, eyomileyo. Umgangatho olungileyo weglasi ye-abicah sealant inokuqinisekisa ngaphezu kweenyanga ezili-12, kunye ne-asilic acid jikelele yeglasi sealant ingagcinwa ngaphezulu kweenyanga ezi-6; i-silicone sealant engathathi hlangothi kunye neglue yesakhiwo inokuqinisekisa ubomi beshelufu ngaphezu kweenyanga ezili-9. Ukuba ibhotile ivuliwe, nceda uyisebenzise ngexesha elifutshane; ukuba i-silicone sealant ayisetyenziswanga, ibhotile kufuneka ivalwe. Xa usebenzisa kwakhona, umlomo webhotile kufuneka ukhululwe ukususa zonke izithintelo okanye ukubuyisela umlomo webhotile.
