A'o su'esu'eina le lalolagi o vaila'au, o le tasi fa'apotopotoga e tu'uta'ua mo lona fa'aogaina ma le fa'aogaina i totonu o alamanuia.tetraethyl silicate. E ui ina foliga lavelave lona fua fa'atatau, o le malamalama o le ki lea i le talisapaia o le auala e fa'aosoina ai e lenei fa'aputuga fa'avevesi taua i matā'upu eseese, mai mea tau eletise i vaila'au. I lenei tusiga, o le a tatou talepeina letetraethyl silicate fuama su'esu'e pe fa'afefea ona a'afia e lona fausaga mole mole ana amio i fa'aoga tau alamanuia.

O le a le Tetraethyl Silicate (TEOS)?

Tetraethyl silicate, e masani ona taʻua oTEOS, o le organosilicon compound ma lefua fa'a vaila'au Si(OC2H5)4. O lenei tuufaatasiga e aofia ai le aatoma silika (Si)fusia i le favaega ethoxy (–OC2H5), faia amole mole tetrahedral. A fa'asusua, e fau TEOSsilika-o se mea autu e faʻaaogaina i le gaosiga o mea faʻaeletoroni, faʻapipiʻi, ma isi faʻaoga eseese.

Malamalama i lonafua fa'a vaila'aue mafai ai ona tatou talisapaia pe aiseatetraethyl silicateose mea taua tele i le tele o alamanuia.

Tu'u i lalo le Fua Fa'atatau Tetraethyl Silicate

Ina ia malamalama i le taua o letetraethyl silicate (Si(OC2H5)4), seʻi o tatou suʻesuʻeina muamua vaega taʻitasi o lonafausaga mole:

•Silicon Atom (Si):O le atoma tutotonu o le mole, silicon, e taua tele i le fausia o sootaga mautu ma le okesene ma le carbon atoms.

•Vaega Ethoxy (–OC2H5):O vaega ta'itasi e fa ethoxy o lo'o faia a'e i se atoma okesene o lo'o pipi'i i se vaega ethyl (C2H5). O le mea lea e fa'atupu ai le TEOS e matua'i fa'agaoioia ma mafai ona fa'ao'o iai ni fa'a'avega fa'ama'i taua e pei ohydrolysismacondensation.

O nei fa'amau e tu'uina atu i le TEOS ni mea fa'apitoa, e fa'asili ona aoga i le fatuinamea fa'avae silicama isi mea fa'apipi'i maualuga.

Fa'afefea ona Fa'aaafia e le Tetraethyl Silicate Fua Fa'atatau Fa'a-Kemimiki

O letetraethyl silicate fuae taua mo le malamalama i ana amio i gaioiga fa'a-kemikolo. O le mea e sili ona taua, o le TEOS o loʻo feagai ma se faʻagasologa e taʻua ohydrolysis, lea e tali atu ai vaega o le ethoxy i le vai, e tau atu i le fausiaina osilikama le ethanol. O lenei tali e fa'avae i le gaosiga oata manifinifi silikama isimea e fa'atatau i le silikoni, e taua tele i mea tau eletise, faʻapipiʻi, ma vailaʻau.

Hydrolysis o Tetraethyl Silicate

Pe a tali atu TEOS i le vai, o vaega ethoxy e suia i vaega hydroxyl, e taʻitaʻia ai le faʻavaeinasilikon hydroxide(Si–OH). O lenei faagasologa e gaosiaethanole pei o se oloa fa'aopoopo. Ole fa'agasologa ole hydrolysis e matua fa'atonuina ile fa'alapotopotoga fa'apisinisi e fa'amautinoa ai le fa'atulagaina ole tulaga maualugasilikameafaitino.

Condensation o Tetraethyl Silicate

A maeʻa le hydrolysis, o levaega hydroxylfausia e mafai ona fegalegaleai ma isi atoms silikoni, taitai atu icondensationtali. O lenei laasaga e fausilikon-okesene-silikoni(Si-O-Si) noataga, e mafua ai le fausiaina o se fausaga fesoʻotaʻiga e taʻua osilika. O le gafatia o le TEOS e fausia ai nei noataga e mafai ai ona saofagā i le fausiaina ofeso'ota'iga silica malosi ma tumau.

Fa'aaogāga ole Tetraethyl Silicate ma Ona Fua Fa'atatau ole Vailaau

O letetraethyl silicate fuama lona fa'agaioiga ua avea ai le TEOS ma vaega taua i le tele o alamanuia:

1. Fa'aeletonika ma Semiconductor Gaosi

TEOS o se fa'amuamua autu i le gaosiga osilicon dioxideata o lo'o fa'aaogaina i totonu o pisinisi fa'aeletonika. E ala i le malamalama i lonafua fa'a vaila'au, e mafai e tagata gaosi oloa ona pulea sa'o leuiga leleimamafiafiao nei ata tifaga, faaleleia le faatinoga omicrochipsmamasini semiconductor.

2. Ufiufi ma Vali

I lealamanuia coatings, TEOS o lo'o fa'aaogaina e fai ai ni fa'amaufa'ailoga puipui, fa'asao-masima mo luga ole laiga. O le faʻavaeina o le silica e ala i le TEOS hydrolysis e faʻamautinoa ai o paʻu e tumau ma umi.

3. Falema'i

O letetraethyl silicate fuae taua foi i lealamanuia tau vailaaumo le gaosiamea fa'aopoopo silica, lea e taua i le fausiaina opapa ma capsules. E fesoasoani le TEOS e fa'aleleia lemautu, bioavailability, mafua faatatau faataapeo mea aoga i vailaau.

Aisea e taua ai le Malamalama i le Tetraethyl Silicate Formula

Ole fua ole kemikolo oletetraethyl silicatee sili atu nai lo na'o se fa'atusa o le fa'apotopotoga. O lo'o tu'uina mai ai fa'amatalaga ile auala e fegalegaleai ai TEOS ma isi vaila'au, pe fa'apefea ona fa'atupusilikafeso'ota'iga, ma pe aisea ua avea ai ma punaoa taua i talosaga tau alamanuia. Pe o totonufaaeletonika, ufiufi, pevaila'au, o le fausaga tulaga ese o le TEOS e mafai ai ona avea o se poloka faufale mo mea e iai mea faʻapitoa.

At Zhangjiagang Fortune Chemical Co., Ltd., matou te tuuto atu i le tuʻuina atu o tulaga maualugatetraethyl silicatemo galuega eseese tau alamanuia. E ala i le malamalama i letetraethyl silicate fuama ana amioga fa'a-kemikolo, e mafai ona e tatalaina le gafatia atoatoa o lenei fa'afefiloi malosi i au oloa ma faiga.
