Ukusetyenziswa
I-ethyl silicate (TEOS) lulwelo olungenambala, olusetyenziswa kakhulu njengeengubo ezimelana nobushushu, iingubo ezimelana neekhemikhali, ii-silane coupling agents, ii-organic synthesis intermediates, kunye ne-precursor yeefilimu ze-chemical vapor deposition (CVD)SiO2 kwicandelo le-semiconductor, njl. Indawo yokunyibilika kwe-ethyl silicate yi--77℃, kwaye indawo yayo yokubila yi-165.5℃. Inyibilika kancinci emanzini kwaye inyibilika kwi-ethanol kunye ne-ether.
Isetyenziswa njengesixhobo sokukhusela ubushushu kwishishini le-elektroniki kwaye ikwasetyenziswa njengearhente yokucubungula iglasi ye-optical kunye ne-coagulant
Isetyenziselwa ukuphoswa ngokuchanekileyo njengesihlanganisi seembombo zesanti; Umphezulu wesinyithi ophathwe ngomphunga we-ethyl silicate unokuthintela ukugqwala namanzi. I-ethyl silicate ingasetyenziselwa ukufunxa umphezulu weentsimbi nge-silicon, kwaye unyango lweglasi ye-optical lunokwandisa ukuhanjiswa kwayo kokukhanya. Umgubo we-silica ocolekileyo kakhulu oveliswa emva kwe-hydrolysis epheleleyo ungasetyenziselwa ukwenza ii-phosphors. I-ethyl silicate yinto eluhlaza eyenziwe ngeoyile ye-silicone. I-ethyl silicate ingasetyenziselwa ukuvelisa iingubo ezimelana nobushushu nezimelana neekhemikhali. EJapan, i-90% ye-ethyl silicate isetyenziswa njengezinto ezisisiseko zeengubo ezimelana nokugqwala (ipeyinti etyebileyo ye-zinc).
Isetyenziswa kakhulu kwiingubo ezimelana neekhemikhali kunye neengubo ezimelana nobushushu, izinyibilikisi zesilicone kunye neeglu ezichanekileyo. Emva kwe-hydrolysis epheleleyo, kuveliswa umgubo we-silicon dioxide ocolekileyo kakhulu, osetyenziselwa ukwenza ii-phosphors kwaye unokusetyenziswa njenge-reagent yeekhemikhali.
I-Tetraethoxysilane isetyenziswa kakhulu kwiglasi ekhanyayo, kwiingubo ezimelana neekhemikhali, kwiingubo ezimelana nobushushu kunye neeglu. Ukuguqulwa kweengubo ezichasene nokugqwala I-arhente edibanisayo, i-binder, i-arhente yokufunxa amanzi; Ukuveliswa kwamathambo e-catalyst kunye ne-silica ecocekileyo kakhulu
I-ethyl orthosilicate isetyenziswa kakhulu kwiglasi ekhanyayo, kwiingubo ezimelana neekhemikhali, kwiingubo ezimelana nobushushu kunye neeglu. Ukuguqulwa kweengubo ezichasene nokugqwala I-Crosslinking agent, i-binder, i-dehydrating agent; Ukuveliswa kwamathambo e-catalyst kunye ne-high-purity ultrafine silica.
Izinto zokukhusela ubushushu kwishishini le-elektroniki, ii-coating, ii-arhente zonyango lweglasi ye-optical, ii-coagulants, i-organic synthesis, izinyibilikisi zokulungiselela i-organosilicon
Kwi-compound efakwe ngaphakathi eyenza i-H+-magadiite, iya kusabela ne-dodecylamine ukuze kufundwe iglasi esebenzayo yesinyithi esixutyiweyo. Isetyenziswa kakhulu njengesandulela ekulungiseleleni iijeli ezomileyo.
Ukupakishwa kunye nokuthunyelwa
Ukupakisha: 200kg ngokweemfuno zabathengi.
Ukuthunyelwa: kungokweekhemikhali eziqhelekileyo kwaye kungathunyelwa ngololiwe, ulwandle nomoya.
Isitokhwe: sinesitokhwe sokhuseleko se-500MTs
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
