I-ethyl silicate: Izinto zomlingo kwicandelo lemizi-mveliso

Kwihlabathi elikhulu lezinto zoshishino, i-ethyl silicate ivelele njengeenkwenkwezi eziqaqambileyo, ezisa ubugcisa kunye nophuhliso kumashishini amaninzi ngeempawu zayo ezizodwa kunye noluhlu olubanzi lwezicelo. I-ethyl silicate lulwelo olungenambala nolucacileyo kubushushu begumbi kwaye lunevumba elikhethekileyo. Kwimeko engenamanzi, izinzile kwaye ithembekile. Nangona kunjalo, yakuba idibene namanzi, iya kubola ngobuchule ibe yi-ethanol kunye ne-silicic acid, kwaye kancinci kancinci ibe yi-turbid emoyeni ofumileyo. Le propati imangalisayo iyenza idlale indima ebalulekileyo kwiimpendulo ezininzi zeekhemikhali kunye nokulungiswa kwezinto. Inyibilika ngokulula kwizinyibilikisi ze-organic ezifana notywala kunye ne-ether, kunye nefomula yemolekyuli ye, indawo yokunyibilika ephantsi njenge, kunye nendawo yokubilisa. Ngokwembono yendlela yokulungiselela, ifunyanwa ngononophelo ngokuhlanjululwa emva kokudibana phakathi kwe-silicon tetrachloride kunye ne-anhydrous ethanol. Le nkqubo yokulungiselela enzima iqinisekisa umgangatho ophezulu kunye nokuzinza kwe-ethyl silicate. Kwizicelo ezisebenzayo, i-ethyl silicate ingathathwa njenge "jack yazo zonke iindlela zorhwebo". Kwicandelo leengubo, yeyona nto iphambili yokwenza iingubo ezimelana nobushushu kunye neekhemikhali. EJapan, ukuya kuthi ga kwi-90% ye-ethyl silicate isetyenziswa njengesiseko sezinto zokugquma ezichasene nokugqwala (ipeyinti etyebileyo ye-zinc). Emva kokutshiza, amaqela e-alkoxy kwisakhiwo sawo se-molecular anokufunxa umswakama emoyeni aze angene kwiimpendulo ze-hydrolysis, ukudibanisa kunye nokuphilisa ukwenza ii-polymers ze-siloxane ezine-molecular ephezulu, ezakha umqobo oqinileyo wokukhusela i-coating. Okwangoku, umgubo we-zinc kwi-coating udlala indima yokukhusela i-electrochemical. Iimveliso zokugqwala zizalisa izithuba zefilimu yokugquma, zithintela ukukhukuliseka kweendaba eziyingozi, zivumela into egqunyiweyo ukuba ihlale ikwimeko entle ixesha elide nakwiindawo ezinzima. Isetyenziswa kakhulu ekwakhiweni kweenqanawa, kwiikhemikhali zepetroli, kwiindawo ezikude nolwandle nakwamanye amasimi. Kwishishini lokuphosa ngokuchanekileyo, i-ethyl silicate ibaluleke ngakumbi. Njenge-binder ye-sand molds, inokuvelisa izinto ezinamandla okubopha emva kwe-hydrolysis. Xa ixutywe nezinto ezichaseneyo zokunyanga isanti yokubumba, emva kokomiswa, kwakheka ifilimu yepropathi ekwaziyo ukumelana nobushushu obuphezulu nefanelekileyo yokubola phezu komphezulu wesanti yokubumba, okwenza umphezulu wesanti yokubumba ube mpuluswa kwaye ukuchaneka kobukhulu kube phezulu kakhulu. Ifanelekile ngokukodwa ekuveliseni iindawo ezichanekileyo kwi-aerospace nakwezinye iindawo. Ayipheleli apho, i-ethyl silicate ingasetyenziswa njengezinto zokukhusela kwishishini le-elektroniki, inika isiqinisekiso sokusebenza okuzinzileyo kwezixhobo ze-elektroniki. Isetyenziselwa ukucubungula iglasi ye-optical, enokunyusa kakhulu ukuhanjiswa kwayo kokukhanya kwaye inike izixhobo ze-optical "intsimi yombono" ecacileyo. Umgubo we-silica ocolekileyo kakhulu oveliswa emva kwe-hydrolysis epheleleyo useyinto ebalulekileyo yokwenza i-phosphors. Ingasetyenziswa nakwi-organic synthesis ukulungiselela izinyibilikisi ze-silicone kwaye yinto ebalulekileyo yokwenza i-silicone oil, idlala indima ebalulekileyo kwihlabathi lezinto ze-silicone. Ukukhetha i-ethyl silicate kuthetha ukukhetha izisombululo zoshishino ezikumgangatho ophezulu nezisebenza kakuhle. Nokuba kukuphucula ukusebenza okukhuselekileyo kunye nokuchaneka kweemveliso zakho okanye ukwandisa amasimi okusetyenziswa kwezinto, i-ethyl silicate inokufaka amandla amakhulu kwimveliso yakho yemizi-mveliso, ikuncede uvelele kushishino kwaye udale amathuba amaninzi!
