Nkuko twese tubizi, muri rusange inyubako ziteganijwe kugira ubuzima bwa serivisi byibuze imyaka 50. Kubwibyo, ibikoresho byakoreshejwe bigomba no kugira ubuzima burebure. Ikirangantego cya silicone cyakoreshejwe cyane mubijyanye no kubaka amazi no gufunga bitewe n’ubushyuhe buhebuje bwo hejuru kandi buke, guhangana n’ikirere cyiza cyane, hamwe n’uburyo bwiza bwo guhuza. Ariko, nyuma yigihe runaka nyuma yubwubatsi, guhindura ibara rya silicone byahindutse ikibazo gikunze kugaragara, bigatuma “imirongo” itunguranye ku nyubako.
Kuki silicone kole ihindura ibara nyuma yo kuyikoresha?
Hariho impamvu nyinshi zo guhindura ibara igice cyangwa cyuzuye cya silicone tunnel kashe cyangwa ibirahuri, cyane cyane mubice bikurikira:
1. Kudahuza ibikoresho bitandukanye bya kashe ya Acide, kashe ya alcool idafite aho ibogamiye, hamwe na kashe ya okisime idafite aho ibogamiye ntishobora gukoreshwa hamwe, kuko ishobora kugira ingaruka kandi igatera ibara. Ikirahuri cya acide kirashobora gutuma kashe ya oxyde ihinduka umuhondo, kandi gukoresha ibirahuri bitagira aho bibogamiye kandi bidafite aho bibogamiye bishingiye ku nzoga hamwe bishobora gutera umuhondo.
Molekile zirekurwa mugihe cyo gukiza kashe yo mu bwoko bwa oxyde idafite aho ibogamiye, -C = N-OH, irashobora kwitwara hamwe na acide kugirango ibe amatsinda amine, ihindurwamo byoroshye na ogisijeni mu kirere kugirango ibe ibintu byamabara, biganisha ku ibara rya kashe.
2. Menyesha reberi nibindi bikoresho
Ikirangantego cya silicone gishobora guhinduka umuhondo mugihe uhuye nubwoko bumwe na bumwe bwa reberi, nka reberi karemano, neoprene reberi, na EPDM rubber. Iyi reberi ikoreshwa cyane murukuta rwumwenda hamwe nidirishya / inzugi nkibikoresho bya reberi, gaseke, nibindi bice. Iri bara rirangwa nuburinganire, hamwe nibice gusa bihuye neza na reberi ihinduka umuhondo mugihe utundi turere dukomeje kutagira ingaruka
3. Ibara rya kashe rishobora nanone guterwa no kurambura cyane
Iyi phenomenon ikunze kwibeshya ko yatakaje ibara rya kashe, ishobora guterwa nibintu bitatu bisanzwe.
1) Ikidodo cyakoreshejwe cyarenze ubushobozi bwo kwimura kandi ingingo yarambuye cyane.
2) Ubunini bwa kashe mu bice bimwe na bimwe ni buke cyane, bigatuma ihinduka ryamabara ryibanze muri utwo turere.
4. Guhindura ibara rya kashe birashobora kandi guterwa nibidukikije.
Ubu bwoko bwo guhindura amabara bukunze kugaragara mubidodo bitagira aho bibogamiye, kandi impamvu nyamukuru yo guhindura ibara ni ukubera ibintu bya aside mu kirere. Hariho amasoko menshi yibintu bya acide mu kirere, nko gukiza acide silicone silicone, impuzu za acrylic zikoreshwa mu bwubatsi, urugero rwa dioxyde de sulfure nyinshi mu kirere mu gihe cy'itumba mu turere two mu majyaruguru, gutwika imyanda ya pulasitike, gutwika asifalt, n'ibindi. Ibi bintu byose bya acide mu kirere birashobora gutera kashe yo mu bwoko bwa oxime guhinduka ibara.
Nigute ushobora kwirinda ibara rya silicone kashe?
1) Mbere yubwubatsi, kora ikizamini cyo guhuza ibikoresho uhuye na kashe kugirango umenye neza ibikoresho, cyangwa uhitemo ibikoresho byinshi byifashishwa, nko guhitamo ibicuruzwa bya silicone aho gukoresha ibicuruzwa kugirango ugabanye amahirwe yo kuba umuhondo.
2) Mugihe cyubwubatsi, kashe idafite aho ibogamiye ntigomba guhura na acide acide. Ibintu bya amine biterwa no kubora kwa kashe idafite aho ibogamiye nyuma yo guhura na aside bizahinduka umwuka mubi kandi bigatera ibara.
3) Irinde guhura cyangwa guhura na kashe kubidukikije byangirika nka acide na alkalis.
4) Guhindura ibara biboneka cyane mubicuruzwa bifite ibara ryoroshye, byera, kandi bibonerana. Guhitamo kashe cyangwa umukara birashobora kugabanya ibyago byo guhinduka ibara.
5) Hitamo kashe ifite ireme ryizewe kandi ryiza ryiza-JUNBOND.
