Tetraethyl silicate(TEOS) ke motsoako oa lik'hemik'hale o sebetsang ka mokhoa o fapaneng o sebelisoang haholo liindastering tse sa tšoaneng. Ho utloisisa ts'ebetso ea eona ho bohlokoa bakeng sa ho ntlafatsa ts'ebeliso ea eona ho motsoako oa lik'hemik'hale le ho feta. Ka blog ena, re tla hlahloba litšobotsi tse ikhethang tsa tetraethyl silicate, ts'ebetso ea eona hape, le hore na e ka bapala karolo ea bohlokoa joang mererong ea hau.

Tetraethyl silicate ke eng?

Tetraethyl silicate ke motsoako oa organosilicon o atisang ho sebelisoa e le selelekela sa motsoako oa thepa ea silika. Sebopeho sa eona sa limolek'hule, se nang le silicon e kopantsoeng le lihlopha tsa ethoxy, se etsa hore e sebetse haholo maemong a itseng. Ts'ebetso ena e ts'ehetsa ts'ebeliso ea eona e pharalletseng ho likoahelo, likhomaretsi, li-sealants le lits'ebetso tsa tlhahiso ea lik'hemik'hale.

Lintlha tsa Bohlokoa tse Susumelletsang Reactivity ea Tetraethyl Silicate

Reactivity ea tetraethyl silicate e ipapisitse le lintlha tse fapaneng, tseo e 'ngoe le e' ngoe e ka susumetsang boitšoaro ba eona karabelong ea lik'hemik'hale:

1.Hydrolysis le Condensation

TEOS e arabela habonolo ka metsi ka mokhoa oa hydrolysis, e senya lihlopha tsa eona tsa ethoxy ho theha lihlopha tsa silanol. Mohato ona hangata o lateloa ke condensation, moo lihlopha tsa silanol li hokahanyang ho etsa marang-rang a silica. Lits'ebetso tsena li bohlokoa ho hlahiseng lisebelisoa tsa sol-gel le metsoako e meng e thehiloeng ho silica.

2.Khetho ea Catalyst

Li-Catalyst li bapala karolo ea bohlokoa ho laola sekhahla le sephetho sa karabelo ea TEOS. Li-catalyst tse nang le asiti hangata li potlakisa hydrolysis, athe li-catalyst tsa mantlha li rata condensation, e lumellang motsoako o ikhethileng o ipapisitseng le litlhoko tse itseng.

3.Maemo a ho itšoara

Thempereichara, pH, le boteng ba solvents ka haholo ama reactivity ea tetraethyl silicate. Mohlala, lithempereichara tse phahameng hangata li eketsa sekhahla sa karabelo, athe lihlapolli tse khethiloeng ka hloko li ka ntlafatsa ho tšoana ha sehlahisoa.

4.Ho tsepamisa maikutlo le ho Kopanya

Khatiso ea TEOS le mokhoa oa ho kopanya li boetse li ama ts'ebetso ea eona. Ho eketsoa butle-butle ha metsi kapa ho kopanya ho laoloang ho etsa bonnete ba hore ho na le hydrolysis e tšoanang le ho thibela gelation pele ho nako, e ka senyang boleng ba sehlahisoa sa ho qetela.

Lisebelisoa tse sebelisang Tetraethyl Silicate Reactivity

Ho utloisisa ts'ebetso ea tetraethyl silicate ho bula mamati a lits'ebetso tse ngata:

•Liaparo tsa silika: TEOS e sebetsa e le selelekela sa ho theha liphahlo tsa silika tse tšoarellang, tse sa keneleng mocheso bakeng sa libaka tse fapaneng.

•Likhomaretsi le Li-Sealants: Bokhoni ba eona ba ho theha maqhama a matla a silika bo etsa hore e be bo loketseng bakeng sa li-adhesives tse sebetsang hantle.

•Tšimoloho ea Lik'hemik'hale: Reactivity ea tetraethyl silicate e sebelisoa ho hlahisa li-catalysts le lisebelisoa tse tsoetseng pele bakeng sa tšebeliso ea indasteri.

•Khalase Manufacturing: TEOS e kenya letsoho tlhahisong ea likhalase tse khethehileng tse nang le lisebelisoa tse ntlafalitsoeng tsa optical le thermal.

Malebela a ho Tšoaroa ka Sireletsehileng Tetraethyl Silicate

Reactivity e phahameng ea tetraethyl silicate e hloka ho ts'oaroa ka nepo ho netefatsa polokeho le ho boloka botsitso ba sehlahisoa:

• Boloka li-TEOS ka lijaneng tse tiisitsoeng ka thata ho thibela liketso tse sa batleheng ka mongobo moeeng.

• Sebelisa thepa e loketseng ea ho itšireletsa (PPE) ha u sebetsa le TEOS ho qoba ho hlohlona ha letlalo le mahlo.

• Sebetsa sebakeng se nang le moea o motle kapa sebelisa likhurumetso tsa mosi ho fokotsa monyetla oa ho pepesehela mouoane.

Qetello

Thereactivity ea tetraethyl silicateke ntlha ea bohlokoa ts'ebelisong ea eona e atileng ho pholletsa le liindasteri. Ka ho utloisisa thepa ea eona le mokhoa oa ho laola karabelo ea eona, o ka notlolla bokhoni ba eona bo felletseng ba merero ea hau. Hore na o ntse o etsa lisebelisoa tse thehiloeng ho silica kapa o ntse o hlahloba metsoako e tsoetseng pele ea lik'hemik'hale, TEOS ke sesebelisoa se matla pokellong ea hau ea lihlomo.
