Lapho uhlola umhlaba wamakhemikhali, inhlanganisela eyodwa egqama ngokuhlukahluka kwayo nokusebenza kwazo zonke izimbonii-tetraethyl silicate. Nakuba ifomula yayo yamakhemikhali ingase ibonakale iyinkimbinkimbi, ukuqonda kuyisihluthulelo sokuqonda ukuthi le nhlanganisela iqhuba kanjani ukusabela kwamakhemikhali okubalulekile emikhakheni ehlukahlukene, kusukela kogesi kuye kwezokwelapha. Kulesi sihloko, sizobe ukuhlukanisaI-tetraethyl silicate ifomulafuthi uhlole ukuthi ukwakheka kwayo kwamangqamuzana kunomthelela kanjani ekuziphatheni kwayo ekusetshenzisweni kwezimboni.

Iyini i-Tetraethyl Silicate (TEOS)?

I-Tetraethyl silicate, eyaziwa ngokuthiI-TEOS, iyinhlanganisela ye-organosilicon ne-ifomula yamakhemikhali Si(OC2H5)4. Le nhlanganisela iqukethe ai-athomu ye-silicon (Si)kuhlanganiswe ezineamaqembu e-ethoxy (–OC2H5), okwenza ai-molecule ye-tetrahedral. Lapho i-hydrolyzed, amafomu e-TEOSi-silica-into ebalulekile esetshenziswa ekukhiqizeni izingxenye ze-elekthronikhi, okokuhlanganisa, nezinye izinhlelo zokusebenza ezahlukahlukene.

Ukuqonda yayoifomula yamakhemikhalikusivumela ukuthi siqonde ukuthi kunganii-tetraethyl silicateiyinhlanganisela ebaluleke kangaka kuzo zonke izimboni eziningi.

Ukwephula Ifomula ye-Tetraethyl Silicate

Ukuze siqonde ukubalulekai-tetraethyl silicate (Si(OC2H5)4), ake siqale sihlole izingxenye zayoisakhiwo samangqamuzana:

•I-Silicon Atom (Si):I-athomu emaphakathi ye-molecule, i-silicon, idlala indima ebalulekile ekwakheni izibopho ezizinzile nge-oxygen nama-athomu e-carbon.

•Amaqembu e-Ethoxy (–OC2H5):Iqembu ngalinye kwamane e-ethoxy lakhiwe i-athomu yomoya-mpilo ehlanganiswe neqembu le-ethyl (C2H5). Lokhu kwenza i-TEOS isebenze kakhulu futhi ikwazi ukubhekana nokusabela kwamakhemikhali okubalulekile njengei-hydrolysisfuthiukujiya.

Lezi zibopho zinikeza i-TEOS izakhiwo eziyingqayizivele, okwenza kube usizo kakhulu ekudaleniizinto ezisekelwe ku-silicanezinye izinhlanganisela eziphambili.

I-Tetraethyl Silicate Formula Ikuthonya Kanjani Ukusabela Kwamakhemikhali

II-tetraethyl silicate ifomulakubalulekile ekuqondeni ukuziphatha kwayo ekuphenduleni kwamakhemikhali. Okuphawuleka kakhulu, i-TEOS idlula inqubo eyaziwa ngokuthii-hydrolysis, lapho amaqembu e-ethoxy asabela khona ngamanzi, okuholela ekwakhekeni kwei-silicakanye ne-ethanol. Lokhu kusabela kuyisisekelo ekukhiqizeniamafilimu amancane e-silicanokunyeizinto ezisekelwe ku-silicon, ezibaluleke kakhulu ku-electronics, coatings, kanye nemithi.

I-Hydrolysis ye-Tetraethyl Silicate

Lapho i-TEOS isabela ngamanzi, amaqembu e-ethoxy athathelwa indawo ngamaqembu e-hydroxyl, okuholela ekwakhekenii-silicon hydroxide(Si–OH). Le nqubo yakhai-ethanolnjengomkhiqizo. Inqubo ye-hydrolysis ilawulwa kakhulu kuzilungiselelo zezimboni ukuqinisekisa ukwakheka kwekhwalithi ephezului-silicaizinto zokwakha.

Ukufingqa kweTetraethyl Silicate

Ngemuva kwe-hydrolysis, i-amaqembu e-hydroxylkwakheka kungaba ukusebenzisana namanye ama-athomu Silicon, okuholelaukujiyaukusabela. Lesi sinyathelo siyakhai-silicon-oxygen-silicon(Si–O–Si) amabhondi, okuholela ekudalweni kwesakhiwo senethiwekhi esaziwa ngokuthii-silica. Ikhono le-TEOS ukwenza lezi zibopho livumela ukuthi lifake isandla ekwakhiweni kweamanethiwekhi e-silica aqinile, aqinile.

Izicelo ze-Tetraethyl Silicate kanye ne-Chemical Formula Yayo

II-tetraethyl silicate ifomulakanye nokusebenza kabusha kwayo kwenza i-TEOS ibe yingxenye ebalulekile ezimbonini eziningana:

1. I-Electronics kanye ne-semiconductor Manufacturing

I-TEOS iyisandulela esibalulekile ekukhiqizenii-silicon dioxideamafilimu asetshenziswa embonini yezogesi. Ngokuqonda yayoifomula yamakhemikhali, abakhiqizi bangakwazi ukulawula ngokunembile i-izingafuthiukujiyakulawa mafilimu, ukwenza ngcono ukusebenza kweama-microchipsfuthiAmadivayisi we-semiconductor.

2. Izingubo kanye Nopende

Kweimboni yezingubo zokugqoka, I-TEOS isetshenziselwa ukwakha izendlalelo ezivikelayo, ezingaklwebhi ezindaweni ezihlukahlukene. Ukwakhiwa kwe-silica ngokusebenzisa i-TEOS hydrolysis kuqinisekisa ukuthi izigqoko ziqinile futhi zihlala isikhathi eside.

3. Imithi

II-tetraethyl silicate ifomulaibalulekile futhi kuimboni yezemithiyokukhiqizaama-excipients e-silica, ezibalulekile ekwakhiweni kweamaphilisi nama-capsules. I-TEOS isiza ukuthuthukisa i-ukuzinza, i-bioavailability, futhiamanani okuqedwazezithako ezisebenzayo emithini.

Kungani Ukuqonda I-Tetraethyl Silicate Formula Matters

Ifomula yamakhemikhali yei-tetraethyl silicatekungaphezu nje kokumelwa kwenhlanganisela. Inikeza ukuqonda ukuthi i-TEOS isebenzisana kanjani namanye amakhemikhali, ukuthi yakha kanjanii-silicaamanethiwekhi, nokuthi kungani kuyinsiza ebaluleke kangaka ezinhlelweni zezimboni. Ukuthi ingenileelectronics, ezinengilazi, nomaezemithi, isakhiwo esiyingqayizivele se-TEOS sivumela ukuthi isebenze njengesakhiwo sokwakha izinto ezinezakhiwo ezihlukile.

At Inkampani Zhangjiagang Fortune Chemical Co., Ltd., sizimisele ukuhlinzeka ngekhwalithi ephezului-tetraethyl silicatengezicelo ezehlukene zezimboni. Ngokuqonda iI-tetraethyl silicate ifomulakanye nokuziphatha kwayo kwamakhemikhali, ungavula amandla aphelele ale nhlanganisela enamandla emikhiqizweni nasezinqubweni zakho.
