Ukusetshenziswa
I-ethyl silicate (TEOS) iwuketshezi olungenambala, olusetshenziswa kakhulu njengezembozo ezingamelani nokushisa, izembozo ezingamelani namakhemikhali, ama-ejenti okuhlanganisa i-silane, ama-organic synthesis intermediates, kanye nesandulela samafilimu e-chemical vapor deposition (CVD)SiO2 ensimini ye-semiconductor, njll. Indawo yokuncibilika kwe-ethyl silicate ingu-77℃, kanti indawo yayo yokubila ingu-165.5℃. Incibilika kancane emanzini futhi incibilika ku-ethanol kanye ne-ether.
Isetshenziswa njengento yokuvikela ugesi embonini ye-elekthronikhi kanye ne-ejenti yokucubungula ingilazi ye-optical kanye ne-coagulant
Isetshenziselwa ukuphonswa ngokunembile njengesihlanganisi sesikhunta sesihlabathi; Ubuso bensimbi obuphathwe ngomusi we-ethyl silicate bungavimbela ukugqwala namanzi. I-ethyl silicate ingasetshenziswa ukufutha ubuso bezinsimbi nge-silicon, futhi ukwelapha ingilazi ebonakalayo kungandisa ukuhanjiswa kwayo kokukhanya. Impuphu ye-silica ecolekile kakhulu ekhiqizwa ngemva kokugeleza okuphelele ingasetshenziswa ukukhiqiza ama-phosphors. I-ethyl silicate iyinto eluhlaza eyenziwe ngamafutha e-silicone. I-ethyl silicate ingasetshenziswa futhi ukukhiqiza izembatho ezingashisi futhi ezingamelani namakhemikhali. EJapane, ama-90% e-ethyl silicate asetshenziswa njengezinto eziyisisekelo zezembatho ezingamelani nokugqwala (upende ocebile nge-zinc).
Isetshenziswa kakhulu ekumbozweni okungamelani namakhemikhali kanye nokumbozwa okungamelani nokushisa, izinyibilikisi ze-silicone kanye nezinamathiseli ezinembile. Ngemva kokumanziswa ngokuphelele, kukhiqizwa i-silicon dioxide powder ecolekile kakhulu, esetshenziselwa ukwenza ama-phosphor futhi ingasetshenziswa njenge-reagent yamakhemikhali.
I-Tetraethoxysilane isetshenziswa kakhulu engilazini ekhanyayo, ezimbozweni ezingamelani namakhemikhali, ezimbozweni ezingamelani nokushisa kanye nezinamathelisi. Ukuguqulwa kwezimbozo ezilwa nokugqwala I-Crosslinking agent, i-binder, i-dehydrating agent; Ukukhiqizwa kwamathambo e-catalyst kanye ne-high-purity ultrafine silica
I-ethyl orthosilicate isetshenziswa kakhulu engilazini ekhanyayo, ezimbozweni ezingamelani namakhemikhali, ezimbozweni ezingamelani nokushisa kanye nezinamathelisi. Ukuguqulwa kwezimbozo ezilwa nokugqwala I-Crosslinking agent, i-binder, i-dehydrating agent; Ukukhiqizwa kwamathambo e-catalyst kanye ne-high-purity ultrafine silica.
Izinto zokuvikela imboni ye-elekthronikhi, izembozo, izinto zokwelapha ingilazi ye-optical, ama-coagulant, ukwakheka kwezinto eziphilayo, izinyibilikisi zokulungiselela i-organosilicon
Ku-compound ehlanganisiwe eyakha i-H+-magadiite, izosabela ne-dodecylamine ukuze kufundwe ingilazi esebenzayo yensimbi exubile. Ivame ukusetshenziswa njengesandulela ekulungiseleleni amajeli omile.
Ukupakisha Nokuthumela
Ukupakisha: 200kg njengezidingo zamakhasimende.
Ukuthunyelwa: kungokwamakhemikhali avamile futhi kungalethwa ngesitimela, ulwandle kanye nomoya.
Isitoko: sinesitoko sokuphepha esingu-500MTs
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
