Pofufuza dziko la mankhwala, gulu limodzi lomwe limadziwika kwambiri chifukwa cha kusinthasintha kwake komanso kugwiritsidwa ntchito m'mafakitale onse.tetraethyl silicate. Ngakhale makonzedwe ake amawonekedwe ovuta, kumvetsetsa ndikofunikira kuti timvetsetse momwe mankhwalawa amayendetsera zinthu zofunikira pamankhwala osiyanasiyana, kuyambira zamagetsi mpaka zamankhwala. M'nkhaniyi, tikambirana zatetraethyl silicate formulandikuwona momwe mamolekyu ake amakhudzira machitidwe ake pamafakitale.

Kodi Tetraethyl Silicate (TEOS) ndi chiyani?

Tetraethyl silicate, yomwe imadziwika kutiTEOS, ndi gulu la organosilicon ndichilinganizo cha mankhwala Si(OC2H5)4. Gululi lili ndi aatomu ya silicon (Si)zogwirizana ndi zinayimagulu a ethoxy (-OC2H5), kupanga amolekyulu ya tetrahedral. Pamene hydrolyzed, TEOS amapangasilika-chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito popanga zida zamagetsi, zokutira, ndi zina zosiyanasiyana.

Kumvetsa zakeChemical formulazimatithandiza kumvetsa chifukwa chaketetraethyl silicatendi chinthu chofunika kwambiri m'mafakitale ambiri.

Kuphwanya Fomula ya Tetraethyl Silicate

Kuti timvetse kufunika kwatetraethyl silicate (Si(OC2H5)4), tiyeni tione kaye zigawo zakekapangidwe ka maselo:

•Atomu ya Silicon (Si):Atomu yapakati ya molekyulu, silicon, imagwira ntchito yofunika kwambiri popanga zomangira zokhazikika ndi maatomu a oxygen ndi carbon.

•Magulu a Ethoxy (–OC2H5):Lililonse mwa magulu anayi a ethoxy amapangidwa ndi atomu ya oxygen yolumikizidwa ku gulu la ethyl (C2H5). Izi zimapangitsa TEOS kukhala yotakasuka komanso yokhoza kuchitapo kanthu kofunikira ngatihydrolysisndicondensation.

Zomangira izi zimapatsa TEOS katundu wapadera, zomwe zimapangitsa kuti zikhale zothandiza kwambiri popangazipangizo zopangidwa ndi silikandi zina zapamwamba zowonjezera.

Momwe Fomula ya Tetraethyl Silicate Imakhudzira Zochita Zamankhwala

Thetetraethyl silicate formulandikofunikira kuti timvetsetse momwe zimagwirira ntchito pamachitidwe amankhwala. Makamaka, TEOS imakumana ndi njira yotchedwahydrolysis, kumene magulu a ethoxy amachitira ndi madzi, zomwe zimatsogolera kupangasilikandi ethanol. Izi ndi zofunika kupangamafilimu a silikandi zinazinthu zopangidwa ndi silicon, zomwe ndizofunikira kwambiri pamagetsi, zokutira, ndi zamankhwala.

Hydrolysis ya Tetraethyl silicate

Pamene TEOS imachita ndi madzi, magulu a ethoxy amasinthidwa ndi magulu a hydroxyl, zomwe zimapangitsa kuti apangesilicon hydroxide(Si-OH). Njirayi imapangaethanolmonga chotulukapo. Njira ya hydrolysis imayendetsedwa kwambiri m'mafakitale kuti zitsimikizire kuti mapangidwe apamwambasilikazipangizo.

Kusintha kwa Tetraethyl Silicate

Pambuyo pa hydrolysis, ndimagulu a hydroxylopangidwa amatha kuyanjana ndi maatomu ena a silicon, omwe amatsogoleracondensationzochita. Njira iyi imakhalasilicon-oksijeni-silicon(Si-O-Si) ma bond, zomwe zimapangitsa kuti pakhale dongosolo la network lomwe limadziwika kutisilika. Kuthekera kwa TEOS kupanga zomangira izi zimalola kuti zithandizire pakupangamaukonde amphamvu, olimba a silika.

Kugwiritsa Ntchito Tetraethyl Silicate ndi Chemical Formula Yake

Thetetraethyl silicate formulandikuchitanso kwake kumapangitsa TEOS kukhala gawo lofunikira m'mafakitale angapo:

1. Electronics ndi Semiconductor Manufacturing

TEOS ndiye kalambulabwalo wofunikira pakupanga kwasilicon dioxidemafilimu omwe amagwiritsidwa ntchito m'makampani amagetsi. Pomvetsa zakeChemical formula, opanga amatha kuwongolera ndendendekhalidwendimakulidweza mafilimu awa, kupititsa patsogolo ntchito zama microchipsndizida za semiconductor.

2. Zopaka ndi Paints

Mumakampani zokutira, TEOS imagwiritsidwa ntchito popanga zigawo zodzitchinjiriza, zosagwirizana ndi zokanda zamalo osiyanasiyana. Mapangidwe a silica kudzera mu TEOS hydrolysis amaonetsetsa kuti zokutira zimakhala zolimba komanso zotalika.

3. Mankhwala

Thetetraethyl silicate formulandi zofunikanso mumakampani opanga mankhwalaza kupangasilika excipients, zomwe ndi zofunika pakupangamapiritsi ndi makapisozi. TEOS imathandizira kusinthabata, kupezeka kwa bioavailability,ndiKuyimitsa mitengoZosakaniza zomwe zimagwira ntchito mu mankhwala.

Chifukwa Chake Kumvetsetsa Tetraethyl Silicate Fomula Nkhani

The chemical chilinganizo chatetraethyl silicatendi zambiri kuposa kungoyimira pagulu. Imapereka chidziwitso cha momwe TEOS imagwirira ntchito ndi mankhwala ena, momwe amapangidwirasilikama network, ndi chifukwa chake ndi chida chofunikira kwambiri pakugwiritsa ntchito mafakitale. Kaya ili mkatizamagetsi, zokutira, kapenamankhwala, mawonekedwe apadera a TEOS amalola kuti ikhale ngati nyumba yopangira zipangizo zomwe zili ndi zinthu zapadera.
