Ikirangantego cyubatswe na silicone kirashobora kwihanganira imbaraga runaka, kandi ibishishwa birwanya ikirere bya silicone bikoreshwa cyane mugushiraho kashe idafite amazi. Ibikoresho bya silicone byubatswe birashobora gukoreshwa murwego rwo hasi kandi birashobora kwihanganira impagarara nuburemere. Silicone yihanganira ikirere ikoreshwa gusa mugukata kandi ntishobora gukoreshwa muburyo bwo gufunga imiterere.
Silicone Yubaka Ikidodo nikidafite aho kibogamiye gikiza inyubako nziza ya silicone ikirere kitagira ikirere. Kurwanya ikirere cyiza cyane, ubushyuhe bwo hejuru nubushyuhe buke -50 ° C + 150 ° C, gufatana neza, birashobora gukururwa no gukoreshwa mubihe bitandukanye byikirere, kandi bigahita bifata nubushyuhe bwo mu kirere, bikiza bikaramba, Hejuru imikorere hamwe na silicone ya silicone ya elastike, irashobora kurwanya isuri karemano nka ogisijeni numunuko, imirasire ya ultraviolet nimvura. Ahanini ikoreshwa mugukata no gufunga inzugi, amadirishya no gushushanya.
Mubipimo byingenzi bya tekiniki byerekana ibimenyetso bya silicone birwanya ikirere, sag, extrudability, nigihe cyo kumisha hejuru biranga imikorere yubwubatsi. Imikorere yikimenyetso cyakize cyihanganira ikirere nubushobozi bwo kwimuka nigipimo cyigihombo kinini. Igipimo cyinshi cyo gutakaza ikirere cyihanganira ikirere gihwanye no gutakaza ubushyuhe bwumuriro wibikoresho byubaka. Nubusanzwe gukora iperereza kumihindagurikire yimikorere yimihindagurikire y’ikirere nyuma yo kuyikoresha igihe kirekire. Iyo igipimo cyigihombo kinini, niko bikomeye imikorere igabanuka nyuma yo gukoresha igihe kirekire.
Igikorwa nyamukuru cya silicone idashobora guhangana nikirere ni ugufunga ingingo hagati yamasahani. Kubera ko amasahani akunze kwibasirwa nubushyuhe bwubushyuhe no guhindura imiterere nyamukuru, ubugari buhuriweho nabwo burahinduka. Ibi bisaba ko ikirere cyihanganira ikirere kigira ubushobozi bwiza bwo kwihanganira kwimuka hamwe, kandi ntibishobora gucika bitewe nimpinduka ndende zigihe kirekire mubugari. bitandukanye.
Silicone Structural Sealant nikintu kimwe, gukiza kutagira aho kibogamiye, kugenewe cyane cyane guteranya guteranya ibirahuri mukubaka urukuta rwumwenda. Irashobora gusohora byoroshye kandi igakoreshwa muburyo butandukanye bwubushyuhe. Wishingikirize ku butumburuke bwo mu kirere kugirango ukire muri modulus nziza, iramba, silicone ya elastique. Igicuruzwa ntigikeneye primer yikirahure, kandi gishobora kubyara neza.
Ibikoresho byubaka bivuga imbaraga nyinshi (imbaraga zo gukomeretsa> 65MPa, ibyuma-ibyuma byiza bya tensile ihuza imbaraga> 30MPa, imbaraga zogosha> 18MPa), irashobora kwihanganira imizigo minini, kandi irwanya gusaza, umunaniro, ruswa, nibikorwa mubuzima buteganijwe. Ihamye, ibereye guhuza imiterere ikomeye. Ibikoresho bidafite imiterere bifite imbaraga nke kandi biramba, kandi birashobora gukoreshwa gusa muguhuza, gufunga no gutunganya imitungo isanzwe nigihe gito, kandi ntishobora gukoreshwa muburyo bwo guhuza imiterere.
