Impeta ya kashe ya silicone ni ubwoko bw'impeta.Ikozwe muri gelika itandukanye ya silika kandi ikoreshwa mugukosora igifuniko cyumwaka kugirango gishobore guhuza icyuho kiri hagati ya ferrule cyangwa gasketi ku cyuma.Iratandukanye nimpeta ya kashe ikozwe mubindi bikoresho.Imikorere yo kurwanya amazi cyangwa kumeneka nibyiza.Kugeza ubu, ikoreshwa cyane cyane mu gufunga amazi no kubungabunga ibikenerwa bya buri munsi nka crisper, guteka umuceri, gutanga amazi, agasanduku ka sasita, igikombe cya magneti, inkono ya kawa, nibindi biroroshye gukoresha, bifite umutekano kandi bitangiza ibidukikije, kandi byimbitse gukundwa na bose.Uyu munsi rero, reka turebe byimbitse impeta ya silicone.
Itandukaniro hagati ya kashe ya silicone nizindi mpeta zifunga ibintu:
1. Kurwanya ikirere cyiza
Kurwanya ikirere bivuga urukurikirane rw'ibintu bishaje nko kuzimangana, guhinduka amabara, guturika, guhiga no gutakaza imbaraga bitewe n'ingaruka z’imiterere yo hanze nk'izuba ryinshi n'izuba ry'ubushyuhe.Imirasire ya Ultraviolet nicyo kintu nyamukuru gitera gusaza ibicuruzwa.Inkunga ya Si-O-Si muri reberi ya silicone ihagaze neza cyane kuri ogisijeni, ozone na ultraviolet, kandi ifite imbaraga zo kurwanya isuri ya ozone na oxyde.Nta nyongeramusaruro, ifite ibihe byiza byo guhangana nikirere, niyo byakoreshwa hanze igihe kinini, ntabwo bizacika.
2. Umutekano wibikoresho no kurengera ibidukikije
Rubber ya silicone ifite ubudahangarwa bwihariye bwa physiologique, idafite uburozi kandi butaryoshye, nta muhondo kandi nta gucika nyuma yo kuyikoresha igihe kirekire, kandi ntibihungabanywa nibidukikije.Yujuje ubuziranenge bwibiryo byigihugu nisuku yubuvuzi.Ikoreshwa cyane mubiribwa, ubuvuzi, aluminium silver paste namavuta atandukanye.urwego rwungurura umwanda kuri.
3. Imikorere myiza yo gukwirakwiza amashanyarazi
Silicone silicone ifite ibikoresho byiza byo gukwirakwiza amashanyarazi, kandi ni byiza cyane mukurwanya corona (ubushobozi bwo kurwanya iyangirika ryiza) hamwe no kurwanya arc (ubushobozi bwo kurwanya kwangirika guterwa nigikorwa cya voltage nini ya arc).
4. Umuyaga mwinshi kandi uhitamo kohereza gaze
Bitewe nuburyo bwa molekile ya silika gel, impeta ya silika gel ifite kashe nziza kandi ihitamo neza imyuka.Ku bushyuhe bwicyumba, gaze ya gaze ya silicone ya rebero mu kirere, azote, ogisijeni, dioxyde de carbone nizindi myuka iruta inshuro 30-50 ugereranije na rubber naturel.ibihe.
5. Hygroscopicity
Ingufu zo hejuru zimpeta ya silicone ziri hasi, zifite umurimo wo gukurura no gukingira ubushuhe mubidukikije.
6. Ubwinshi bwubushyuhe bwo hejuru kandi buke
(1).Kurwanya ubushyuhe bwinshi:Ugereranije na reberi isanzwe, impeta ifunga ikozwe muri silika gel irwanya ubushyuhe bwiza, kandi irashobora gushyuha mubushyuhe bwinshi nta guhindagurika kandi idatanga ibintu byangiza.Irashobora gukoreshwa hafi yigihe cyose kuri 150 ° C idahinduye imikorere, irashobora gukoreshwa ubudahwema kuri 200 ° C mumasaha 10,000, kandi irashobora gukoreshwa kuri 350 ° C mugihe runaka.Byakoreshejwe cyane mubihe bisaba kurwanya ubushyuhe, nka: icupa rya termo.
(2).Kurwanya ubushyuhe buke:Rubber isanzwe izakomera kandi ivunaguritse kuri -20 ° C kugeza kuri 30 ° C, mugihe reberi ya silicone iracyafite elastique nziza kuri -60 ° C kugeza kuri 70 ° C.Ibikoresho bimwe na bimwe byakozwe na silicone reberi Irashobora kandi kwihanganira ubushyuhe bukabije bukabije, nka: impeta ya kriogene, impeta yo hasi irashobora kugera kuri -100 ° C.
Ingaruka za kashe ya silicone:
(1).Imiterere yubukorikori bwimbaraga zingutu nimbaraga zamarira ni mbi.Ntabwo byemewe gukoresha impeta ya silicone yo kurambura, kurira, no kwambara cyane mubikorwa.Mubisanzwe, ikoreshwa gusa mugushiraho ikimenyetso.
(2).Nubwo reberi ya silicone ihujwe namavuta menshi, ibivangwa hamwe nuwashonga, kandi ifite aside nziza na anti-alkali, ntabwo irwanya hydrogène ya alkyl hamwe namavuta ya aromati.Kubwibyo, ntibikwiye gukoreshwa mubidukikije aho umuvuduko wakazi urenga ibiro 50.Byongeye kandi, ntabwo byemewe gukoresha kashe ya silicone mumashanyarazi menshi, amavuta, acide yibanze hamwe na soda ya caustic soda.
(3).Kubijyanye nigiciro, ugereranije nibindi bikoresho, igiciro cyo gukora silicone gifunga impeta ya reberi ni kinini.
