Tetraethyl silicate(TEOS) nuruvange rwimiti itandukanye ikoreshwa cyane mubikorwa bitandukanye. Gusobanukirwa nubushobozi bwayo nibyingenzi mugutezimbere ikoreshwa ryayo muri synthesis ya chimique ndetse no hanze yacyo. Muri iyi blog, tuzasesengura imiterere yihariye ya tetraethyl silikatike, reaction yayo, nuburyo ishobora kugira uruhare runini mumishinga yawe.

Tetraethyl Silicate ni iki?

Tetraethyl silicate ni uruganda rwa organosilicon rusanzwe rukoreshwa nkibibanziriza muguhuza ibikoresho bishingiye kuri silika. Imiterere ya molekile yayo, igizwe na silicon ihujwe nitsinda rya ethoxy, ituma ikora cyane mubihe byihariye. Iyi reaction irashimangira akamaro kanini mugutwikira, gufatisha, kashe, hamwe nuburyo bwo gukora imiti.

Ibintu by'ingenzi bigira ingaruka kuri reaction ya Tetraethyl Silicate

Imyitwarire ya siliketi ya tetraethyl iterwa nibintu bitandukanye, buri kimwe muri byo gishobora kugira ingaruka zikomeye kumyitwarire yacyo mumiti:

1.Hydrolysis hamwe na Condensation

TEOS ikora byoroshye namazi mugikorwa cya hydrolysis, isenya amatsinda yayo ya ethoxy kugirango ibe amatsinda ya silanol. Iyi ntambwe ikurikirwa na kondegene, aho amatsinda ya silanol ahuza gukora imiyoboro ya silika. Izi reaction ningenzi mugukora ibikoresho bya sol-gel nibindi bikoresho bishingiye kuri silika.

2.Guhitamo Catalizike

Catalizator igira uruhare runini mugucunga igipimo nigisubizo cya TEOS. Catisale ya acide mubisanzwe yihutisha hydrolysis, mugihe catalizaires yibanze ituma habaho kwegeranya, bigatuma synthesis ikomatanyije ishingiye kubisabwa byihariye.

3.Ibisabwa

Ubushyuhe, pH, no kuba hari ibishishwa birashobora kugira ingaruka zikomeye kuri reaction ya tetraethyl silicate. Kurugero, ubushyuhe bwo hejuru muri rusange bwongera igipimo cyibisubizo, mugihe byatoranijwe neza byashizwe hejuru bishobora kuzamura ibicuruzwa.

4.Kwibanda no Kuvanga

Kwishyira hamwe kwa TEOS nuburyo bwo kuvanga nabyo bigira ingaruka kubikorwa byayo. Kwiyongera buhoro buhoro amazi cyangwa kuvangwa bigenzurwa bituma hydrolysis imwe kandi ikarinda kwangirika imburagihe, bishobora guhungabanya ubuziranenge bwibicuruzwa byanyuma.

Porogaramu Gukoresha Tetraethyl Silicate Reactivite

Gusobanukirwa na reaction ya tetraethyl silikate ifungura imiryango kubikorwa byinshi:

•Silica: TEOS ikora nkibibanziriza kurema silika iramba, idashobora kwihanganira ubushyuhe butandukanye.

•Ibifunga hamwe na kashe: Ubushobozi bwayo bwo gukora silika ikomeye ituma biba byiza kubikorwa bifatika.

•Synthesis: Imyitwarire ya siliketi ya tetraethyl ikoreshwa mugukora catalizator nibikoresho bigezweho byo gukoresha inganda.

•Gukora ibirahure: TEOS igira uruhare mu gukora ibirahuri byihariye hamwe na optique hamwe nubushyuhe bwo hejuru.

Inama zo gufata neza umutekano wa Tetraethyl Silicate

Kwiyongera kwinshi kwa tetraethyl silikate bisaba gufata neza kugirango umutekano ubungabunge kandi ubungabunge ibicuruzwa:

• Bika TEOS mubikoresho bifunze neza kugirango wirinde ingaruka zidakenewe hamwe nubushyuhe bwo mu kirere.

• Koresha ibikoresho byihariye byo kurinda (PPE) mugihe ukorana na TEOS kugirango wirinde uruhu n'amaso.

• Kora ahantu hafite umwuka mwiza cyangwa ukoreshe fume kugirango ugabanye imyuka.

Umwanzuro

Uwitekareaction ya tetraethyl silicateni ikintu cyingenzi mugukoresha kwinshi mu nganda. Mugusobanukirwa imiterere yabyo nuburyo bwo kugenzura reaction zayo, urashobora gufungura ubushobozi bwuzuye kubikorwa byawe. Waba utezimbere ibikoresho bishingiye kuri silika cyangwa ugashakisha synthèse yimiti igezweho, TEOS nigikoresho gikomeye muri arsenal yawe.
