Xa usiva 'utyalo-mali,' ingqondo itsibela kwiipateni zewax kunye namaqokobhe eceramic. I i-silicone ye-sol Foundry inxalenye? Elo lidla ngokuba lihashe elizolileyo neliqondwa kakubi elo. Abaninzi bacinga ukuba kukuthenga i-emele ye-binder. Inyaniso kukuba, i-sol-ukuba i-colloidal silica suspension-kulapho inkqubo iphumelele okanye ilahleke ixesha elide ngaphambi kokuba nayiphi na isinyithi igalelwe. Ndikhe ndazibona iivenkile zithe phithi zii-specs ze-alloy ngelixa ziphatha inkqubo yazo ye-sol njengengcamango yamva, impazamo eneendleko ezinkulu.
I-Sol ayiyonto nje iGlue; Luyilo lwezakhiwo
Kwi-a utyalo mali isiseko, umsebenzi we-sol kukugquma umgubo ngamnye we-zircon okanye i-alumina silicate grain, ukwakha umaleko weqokobhe ngokwemaleko. Umgangatho we-gelation-indlela eguquka ngayo ukusuka kwi-liquid ukuya kwi-gel-ilawula amandla egobolondo kunye nokunyanzeliswa. Ngokukhawuleza kakhulu, kwaye ufumana i-brittle, i-micro-cracked layers. Ukucotha kakhulu, kwaye umgca wakho wemveliso uyasila ume. Ndikhumbula iprojekthi apho satshintshela kwisol entsha, 'esebenza kakhulu' sisuka kumboneleli owahlukileyo. Iimpawu zazijongeka zigqibelele ephepheni. Ngokwesiqhelo, ixesha lejeli lalinobuntununtunu kakhulu kumanzi aphantsi evenkileni, okukhokelela kubunzima obungahambelaniyo beqokobhe kunye nephupha elibi lokuqhekeka kweqokobhe ngexesha lokukhutshwa kwewaxing.
