Zvinoenderana neakasiyana mabhaidha echivakwa chegoko, iyo yekukanda mari inogona kukamurwa kuita silica sol binder investimendi yekukandira, mvura girazi binder investimendi kukanda uye mari yekukanda nemisanganiswa yavo sebinder zvinhu. Silica sol yakajairika mvura-based binder ine silicic acid colloid chimiro. Iyo polymer colloidal mhinduro umo yakapararira zvakanyanya silica particles inonyungudika mumvura. Iyo colloidal particles ine spherical uye ine dhayamita ye6-100 nm. Iyo nzira yekukandira mari kugadzira iyo goko ndiyo maitiro ekugelling. Pane zvinhu zvakawanda zvinopesvedzera gelation, kunyanya electrolyte, pH, sol concentration uye tembiricha. Kune akawanda marudzi ekutengesa silica sols, uye inonyanya kushandiswa ndeye alkaline silica sol ine silica yemukati ye30%. Kuti ukunde kusakwana kweiyo refu-yekugadzira goko reiyo silica sol shell, inokurumidza-kuomesa silica sol yakagadzirwa mumakore achangopfuura. Maitiro ekugadzira silica sol shell ari nyore. Nzira imwe neimwe ine maitiro matatu: kupfekedza, kuisa jecha, uye kuomesa. Maitiro ega ega anodzokororwa kakawanda kuti awane multilayer goko rehukobvu hunodiwa.
Mu silica sol shell kugadzira maitiro, kuomesa ndiyo inonyanya kukosha maitiro. Kuburikidza nekuomeswa, mvura inoputika, iyo silica sol gels, uye zvimedu zvinoramba zvakasunganidzwa zvakasimba pamwe chete, nokudaro zvichiwana goko rakasimba. Iyi igadziriro yakanaka yekukanda kunotevera. Iko kukanda kunowanikwa ne silica sol shell kugadzira maitiro kune yakaderera pamusoro roughness, yakakwirira dimensional kunyatsoita uye kureba shell kugadzira kutenderera. Iyi nzira inoshandiswa zvakanyanya mukukanda alloys anodzivirira kupisa-kupisa, masimbi asingasviki, simbi isina tsvina, carbon steels, low alloys, aluminium alloys uye copper alloys.
Iyo silica sol chaiyo yakarasika wax yekudyara yekukandira maitiro inokodzera kudzokororwa kugadzirwa kwe mambure maumbirwo ezvikamu kubva kune akasiyana siyana simbi uye yakakwirira performance alloys. Kunyange zvazvo ichiwanzo shandiswa kuita zvidiki zvekukandira, maitiro aya akashandiswa kugadzira mafuremu emadhoo endege akazara, ane simbi inokandwa inosvika 500 kgs uye aluminium castings inosvika makumi mashanu kgs. Kuenzaniswa nemamwe maitiro ekukanda akadai sekukanda kufa kana jecha, inogona kuve inodhura maitiro. Nekudaro, izvo zvikamu zvinogona kugadzirwa uchishandisa investment casting inogona kusanganisira yakaoma contours, uye kazhinji zvikamu zvinokandwa padhuze net mambure, saka zvinoda kushoma kana kusazoitwazve kana ikandwa.
Zvinoenderana nehuwandu hwekabhoni yemukati, kabhoni simbi yekukanda inowanzo patsanurwa kuita yakaderera kabhoni simbi, yepakati kabhoni simbi uye yakakwira kabhoni simbi. Iyo yakakandwa kabhoni simbi dzenyika dzese pasirese dzinowanzo kupatsanurwa maererano nesimba radzo, uye mamakisi anoenderana anogadzirwa.
Nezve chemikemikari yekabhoni simbi, kunze kwephosphorous nesarufa, hapana zvirambidzo kana chete miganhu yepamusoro pane mamwe makemikari zvinhu. Pasi pechinhu chiri pamusoro apa, kemikari yekabhoni yakakandwa simbi inotemerwa neiyo foundry zvinoenderana neinodiwa mechanical properties.
Iyo nzira dzekupisa dzekupisa dzekabhoni simbi castings dzinowanzo annealing, normalizing kana normalizing + tempering. Kune mamwe akakwira kabhoni simbi castings, kudzima uye kupisa kunogona kushandiswa zvakare, ndiko kuti, kudzima + tembiricha yekupisa, kuitira kuti uvandudze hwakakwana hwemichina yekabhoni simbi castings. Diki kabhoni simbi castings inogona kudzimwa zvakananga uye kudzikamiswa kubva kune-yakakanda nyika. Kune yakakura-yakakura kana yakaoma-yakaita kabhoni simbi castings, zvakakodzera kuita quenching uye tempering kurapwa pashure normalizing kurapwa.
Mundima yekukanda uye metallurgical industry, ferrous metals (ferrous metals) zvinoreva simbi nemaaloyi ayo ane iron. Iyo simbi yesimbi inosanganisira simbi nenguruve simbi uye nheyo dzinowanzozvipatsanura kuita mapoka makuru maviri: simbi yakakandwa (grey cast iron, ductile cast iron, malleable cast iron, vermicular graphite cast iron etc.) uye simbi yakakandwa (cast carbon steel, cast. alloy simbi, Stainless simbi etc). Nekukanda foam yakarasika maitiro, RMC Casting Foundry inogona kudurura grey iron, ductile iron, alloy simbi uye kabhoni simbi.
