Tetraethyl silicate (TEOS)ose vaila'au vaila'au o lo'o faia se sao taua i pisinisi eseese, mai mea fa'aeletonika i vaila'au. E ui atonu e le o se igoa aiga, malamalama i lonafausaga molee taua i le talisapaiaina o lona faʻaogaina ma le faʻaogaina. I totonu o lenei tusiga, o le a tatou vaʻavaʻai i lefausaga tetraethyl silicate, pe fa'afefea ona fausia, ma le taua o lo'o umia i le tele o alamanuia. Se'i tatou su'esu'e pe aisea ua matua'i fa'atauaina ai lenei fa'apotopotoga.

O le a le Tetraethyl Silicate?

Ae tatou te le'i su'esu'e i lona fausaga, se'i o tatou faauiga muamua le meatetraethyl silicateo. O le TEOS o se faʻapipiʻi organosilicon faʻatasi ai ma le vailaʻau vailaʻauSi(OC2H5)4. E lauiloa foi otetraethyl orthosilicatema o lo'o fa'aaogaina muamua e fai ma mea muamua i le gaosiga o mea fa'avae silica, e aofia ai faiga sol-gel.

O lenei vai e leai ni lanu, mumu ua faʻaaogaina mo le tele o tausaga, aemaise lava i le gaosiga osilicon dioxide, lea e taua i mea faʻaeletonika, paʻu, ma e oʻo lava i le faʻamalosia o le gaosiga o gaosiga o oloa eseese.

Fa'aleaga i lalo le Fa'atulagaga Tetraethyl Silicate

Ia malamalama moni pe faapefeagalue tetraethyl silicate, e taua le iloiloina o lonafausaga mole. O le mole mole e aofia ai se totonugalemuatoma silika (Si), lea e fusia i vaega e fa ethoxy(–OCH2CH3). O nei vaega ethoxy o loʻo faʻapipiʻiina i le kasa silikon enoataga tasi, ma o vaega ethoxy taitasi o loʻo i ai seatomo okesenefesootai i sevaega ethyl (C2H5).

O lona uiga,tetraethyl silicateo se mole mole tetrahedral ma leatoma silikoninofo i le ogatotonu o le fausaga, e siomia e le favaega ethoxy. O lenei faʻatulagaga e le gata ina mautu ae faʻatagaina foi le TEOS e avea ma se faʻalavelave maualuga, e mafai ona mauahydrolysis ma condensation talie faifeso'ota'iga silika.

Le Matafaioi a Tetraethyl Silicate i Alamanuia

O lefausaga tetraethyl silicatee iai sona aafiaga loloto i lona aoga i vaega eseese. Seʻi o tatou suʻesuʻeina ni nai pisinisi e manuia mai TEOS:

1. Alamanuia Fa'aeletonika ma Semiconductor

I lealamanuia faaeletonika, TEOS e faʻaaoga muamua e fatu aiata manifinifii luga o le semiconductor wafers. O nei ata tifaga e mana'omia mo le fa'amamaina o ta'amilosaga ma le puipuia o vaega ma'ale'ale. Pe a feagai le TEOShydrolysis ma condensation, e fai ai se vaega manifinifi, tutusa tutusa osilikai luga o le substrate, o se faiga taua i totonugaosiga fa'atasi (IC)..

2. Fa'alava ma Vali

O lefausaga tetraethyl silicatee iai fo'i sona sao i le gaosiga o fa'alavalava ma vali. Pe a faʻaaogaina TEOS ifaiga sol-gel, e fesoasoani i le fausia o se umi,tete'e masiufiufi. O lenei faiga e lauiloa ita'avale ta'avale, mata tioata, maufiufi puipuimo metala.

3. Falema'i

I lealamanuia tau vailaau, Tetraethyl silicate o nisi taimi e faʻaaogaina i le gaosiga omea e fa'atatau i le silicamo papa ma capsules. O nei mea fa'aopoopo e iai sona sao taua i totonufaiga o fualaau faasaina, fa'aleleiatilivaina fualaaumabioavailability. E mafai e le silica maua mai TEOS ona faʻaleleia atili le solubility ma le mautu o nisi vailaʻau, ma sili atu le aoga mo gasegase.

Aisea e taua ai le fa'atulagaina o le Tetraethyl Silicate?

O lefausaga tetraethyl silicateo le ki lea i lona fa'aogaina ma le fa'aogaina lautele i nei alamanuia. O le molefaatulagaga tetrahedrale mafai ai ona fa'afeso'ota'i fa'atasi ma isi mea, e fa'atupu ai mea mautu, mautu. O lona gafatia e tali atu i le vai, e tau atu ihydrolysis, ona faia leatali condensation, e avea o se mea muamua lelei mo le gaosigasilika—se mea e iloa aimalosi, tete'e i vaila'au, ma mea fa'amama.

O levaega ethoxyi luga ole kakono atomu e faia foi TEOS maualuga soluble isolvents organic, faʻaleleia lona gafatia e faʻaaogaina i le tele o gaioiga faʻapisinisi.

Le Lumanai o Tetraethyl Silicate

A'o fa'aauau pea ona una'ia e alamanuia mo mea e sili atu ona lelei, umi, ma gafataulimaina, o le taua o le tetraethyl silicate ua na'o le fa'atupuina. Faatasi ai ma le faateleina o le manaoga momasini fa'aeletonika fa'atauva'a, faʻapipiʻi maualuga, mamea fa'akomepiuta, E foliga mai o le a tumau pea le TEOS i le pito i luma o mea fou faʻatekonolosi.

O lonaagava'amagaioigaia mautinoatetraethyl silicateo le a faʻaauau pea ona faia se sao taua i le atinaʻeina o oloa fou ma tekonolosi.

Fa'aaoga le Mana ole Tetraethyl Silicate mo lau Alamanuia

Pe oe galue i mea tau eletise, fa'alavalava, po'o vaila'au, malamalama i lefausaga tetraethyl silicatema o ona uiga mole mole e taua tele i le fa'ateleina o lona gafatia. Faatasi ai ma lona tomai tulaga ese e fai aimea fa'avae silicafa'atasi ai ma meatotino mata'ina, o lo'o tumau pea le TEOS ose tu'ufa'atasiga mana'omia ile tele o alamanuia.

At Zhangjiagang Fortune Chemical Co., Ltd., matou te faʻapitoa i le tuʻuina atu o le silicate tetraethyl silicate mo le tele o faʻaoga. Afai o lo'o e va'ava'ai e fa'aleleia le fa'atinoga o au oloa,faafesootai matou i le asoe iloa ai le auala e mafai ai e TEOS ona fesoasoani i lau pisinisi ia manuia!
