I-silica sol casting iyinqubo yokuphonsa esebenzisa i-silica sol (isixazululo se-silica) njengezinto ezihlanganisayo ukuze kwakhiwe isikhunta sokuphonsa. Ukulingwa kwensimbi okukhiqizwe i-silica sol casting kunezindawo ezinhle nokunemba okuphezulu futhi izinga lokubekezelela ububanzi lifinyelela ku-CT4 - CT6. Futhi le nqubo iyinqubo yokutshala imali eyinhloko ye-RMC yokusakazwa kwensimbi engagqwali kanye ne-alloy steel castings. Besithuthukisa ubuchwepheshe obusha bezinto ezinamathelayo ukuze sifinyelele izinto ezinamathelayo ezinomnotho futhi ezisebenzayo embonini yokutshala imali.

Kuwumkhuba omangalisayo ukuthi inqubo ye-silica sol casting ingena esikhundleni senqubo yengilazi yamanzi esezingeni eliphansi embonini yokuphonsa enembile, ikakhulukazi yokusakazwa kwensimbi engagqwali kanye nokusakazwa kwensimbi yengxubevange. Ngaphandle kwempahla yokubumba esunguliwe, inqubo ye-silica sol casting nayo iye yasungulwa ukuze izinze futhi ikhulise ukushisa okuncane.
Ukutshala imali (i-wax elahlekile) kuyindlela yokusakaza enembayo ekhiqiza imininingwane eyinkimbinkimbi yomumo we-net-net kusetshenziswa ukuphindaphinda kwamaphethini we-wax.Ukutshala imalinoma i-wax elahlekile iyinqubo yokwenza insimbi ngokuvamile esebenzisa iphethini ye-wax ezungezwe igobolondo le-ceramic ukwenza isikhunta se-ceramic. Lapho igobolondo loma, ingcina iyancibilika, kusale isikhunta kuphela. Khona-ke ingxenye yokuphonsa ikhiwa ngokuthululela insimbi encibilikisiwe esikhunjini se-ceramic.
Ngokuvumelana nezihlanganisi ezihlukene zokwakha amagobolondo, ukufakwa kwe-investimenti kungahlukaniswa ngokufaka utshalomali kwe-silica sol binder, ukusakaza kwe-investment binder yengilazi yamanzi kanye nokufaka utshalomali ngezingxube zakhona njengezinto ezihlanganisayo. I-silica sol iyisibopho esivamile esisekelwe emanzini esine-silicic acid colloid structure. Kuyisixazululo se-polymer colloidal lapho izinhlayiya ze-silica ezihlakazeke kakhulu zincibilika emanzini. Izinhlayiya ze-colloidal ziyindilinga futhi zinobubanzi obungu-6-100nm. Inqubo yokutshala izimali ukwenza igobolondo yinqubo yokugaya. Kunezici eziningi ezithonya i-gelation, ikakhulukazi i-electrolyte, i-pH, ukugxila kwe-sol kanye nezinga lokushisa. Kunezinhlobo eziningi zama-silica sols ezithengiswayo, futhi esetshenziswa kakhulu i-alkaline silica sol enokuqukethwe kwe-silica okungama-30%. Ukuze unqobe ukushiyeka komjikelezo omude wokwenza amagobolondo wegobolondo le-silica sol, i-silica sol eyomisa ngokushesha iye yathuthukiswa eminyakeni yamuva. Inqubo yokwenza igobolondo le-silica sol ilula. Inqubo ngayinye inezinqubo ezintathu: ukumboza, ukuhlanganisa, nokomisa. Inqubo ngayinye iphindaphindiwe izikhathi eziningi ukuze uthole igobolondo le-multilayer lobukhulu obudingekayo.
Enqubweni yokwenza igobolondo le-silica sol, ukomisa kuyinqubo ebaluleke kakhulu. Ngokumiswa, amanzi ayashintshashintsha, ama-silica sol gels, kanye nezinhlayiya eziphikisayo zihlanganiswe ngokuqinile ndawonye, ngaleyo ndlela zithola igobolondo lamandla aphezulu. Lokhu ukulungiselela okuhle kokulingisa okulandelayo.
Ukubunjwa okutholwe inqubo yokwenza igobolondo le-silica sol kunobugwegwe obuphansi, ukunemba kobukhulu obuphakeme kanye nomjikelezo omude wokwenza amagobolondo. Le nqubo isetshenziswa kakhulu ekukhipheni ama-alloys amelana nokushisa okuphezulu, izinsimbi ezikwazi ukumelana nokushisa, izinsimbi ezingenasici, izinsimbi ze-carbon, ama-alloys aphansi, ama-alloys e-aluminium nama-alloys ethusi.
I-silica sol ukunemba elahlekile inqubo yokutshala imali ye-wax ilungele ukukhiqizwa okuphindaphindiwe kweizingxenye zokuphonsa umumo wenethakusuka ezinhlobonhlobo zezinsimbi ezahlukene kanye nama-alloys okusebenza okuphezulu. Nakuba ngokuvamile isetshenziselwa ukulingisa okuncane, le nqubo isetshenziselwe ukukhiqiza amafreyimu eminyango yendiza ephelele, enensimbi efika ku-500 kgs kanye nokusakazwa kwe-aluminium kufika ku-50 kgs. Uma kuqhathaniswa nezinye izinqubo zokulingisa ezifana ne-die casting nomaukuphonsa isihlabathi, kungaba inqubo ebizayo. Kodwa-ke, izakhi ezingakhiqizwa kusetshenziswa ukufakwa kwe-investimenti zingahlanganisa amakhonsathi ayinkimbinkimbi, futhi ezimeni eziningi izingxenye ziphonswa eduze komumo wengqikithi, ngakho-ke zidinga ukusetshenzwa kabusha okuncane noma zingasasebenzi lapho kwasakazwa.
