Amfani
Ethyl silicate (TEOS) ruwa ne mara launi, wanda galibi ana amfani da shi azaman murfin da ke jure zafi, murfin da ke jure sinadarai, wakilan haɗin silane, tsaka-tsakin haɗa sinadarai, kuma azaman abin da ke haifar da adana tururin sinadarai (CVD)SiO2 a cikin filin semiconductor, da sauransu. Wurin narkewar ethyl silicate shine -77℃, kuma wurin tafasarsa shine 165.5℃. Yana narkewa kaɗan a cikin ruwa kuma yana narkewa a cikin ethanol da ether.
Ana amfani da shi azaman kayan rufewa a masana'antar lantarki da kuma azaman wakilin sarrafawa don gilashin gani da kuma coagulant
Ana amfani da shi don yin simintin daidai a matsayin abin ɗaurewa ga ƙirar yashi; saman ƙarfe da aka yi wa magani da tururin ethyl silicate na iya hana tsatsa da ruwa. Ana iya amfani da ethyl silicate don sanyaya saman ƙarfe da silicon, kuma gilashin gani mai laushi zai iya ƙara yawan haskensa. Ana iya amfani da foda silica mai laushi sosai bayan cikakken hydrolysis don ƙera phosphors. Ethyl silicate shine kayan da aka samo daga man silicone. Hakanan ana iya amfani da ethyl silicate don ƙera rufin da ke jure zafi da sinadarai. A Japan, ana amfani da 90% na ethyl silicate a matsayin kayan tushe don rufin hana tsatsa (fenti mai arzikin zinc).
Ana amfani da shi galibi a cikin shafa mai jure wa sinadarai da kuma shafa mai jure wa zafi, sinadarin silicone da mannewa daidai gwargwado. Bayan cikakken hydrolysis, ana samar da foda silicon dioxide mai kyau sosai, wanda ake amfani da shi don yin phosphorus kuma ana iya amfani da shi azaman reagent na sinadarai.
Ana amfani da Tetraethoxysilane galibi a cikin gilashin gani, shafa mai jure sinadarai, shafa mai jure zafi da manne. Gyaran shafa mai hana tsatsa. Maganin haɗin gwiwa, mai ɗaurewa, wakili mai bushewa; Kera kwarangwal mai kara kuzari da silica mai tsarki.
Ana amfani da Ethyl orthosilicate galibi a cikin gilashin gani, shafa mai jure sinadarai, shafa mai jure zafi da manne. Gyaran shafa mai hana tsatsa. Maganin haɗin gwiwa, manne, wakili mai bushewa; Kera kwarangwal mai kara kuzari da silica mai tsafta.
Kayan rufi don masana'antar lantarki, shafi, wakilan maganin gilashin gani, coagulants, hadadden halitta, da sauran sinadarai don shirya organosilicon
A cikin sinadarin da aka haɗa wanda ya samar da H+-magadiite, zai yi aiki da dodecylamine don nazarin gilashin bioactive na ƙarfe mai gauraye. Ana amfani da shi galibi azaman abin da zai fara shirya busassun gels.
Marufi da Jigilar Kaya
Marufi: 200kg a matsayin buƙatun abokin ciniki.
Jigilar kaya: nasa ne da sinadarai na yau da kullun kuma ana iya isar da shi ta jirgin ƙasa, teku da iska.
Hannun jari: suna da hannun jarin tsaro na 500MTs
Ajiyewa da adanawa
Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
