Silica Sol Last Wax Sehlahisoa sa ho Lahlela

Ke mokhoa o makatsang oa hore silika ea tšepe e nke sebaka sa ts'ebetso ea khalase ea metsi e tlase e tlase indastering ea ho lahla ka mokhoa o nepahetseng, haholo bakeng sa ho lahla tšepe e sa hloekang le tšepe ea alloy. Ntle le lisebelisoa tse ncha tsa ho bopa, mokhoa oa ho lahla ha silica sol o boetse oa ntlafatsoa hore o be matla haholoanyane 'me o atolose mocheso o fokolang.

Investment (lost wax) ho lahla ke mokhoa oa ho lahla ka mokhoa o nepahetseng o hlahisang lintlha tse rarahaneng tsa sebopeho sa marang-rang ho sebelisa mokhoa oa ho pheta-pheta mekhoa ea boka.Ho kenya cheletekapa boka ba bokae ke mokhoa oa ho etsa tšepe oo ka tloaelo o sebelisang mohlala oa boka o pota-potiloeng ke khetla ea ceramic ho etsa hlobo ea ceramic. Ha khetla e omella, boka ba linotsi boa qhibiliha, ebe ho sala hlobo feela. Ebe karolo ea ho lahla e thehoa ka ho tšela tšepe e qhibilihisitsoeng ka har'a hlobo ea ceramic.

Ho ea ka li-binders tse fapaneng bakeng sa mohaho oa likhetla, ts'ebetso ea lichelete e ka aroloa ka silika sol binder investing casting, metsi a glass binder investing casting le investing ea matsete ka metsoako ea bona e le lisebelisoa tse tlamang. Silica sol ke setlamo se tloaelehileng sa metsi se nang le sebopeho sa silicic acid colloid. Ke tharollo ea polymer colloidal moo likaroloana tsa silica tse qhalakaneng haholo li qhibilihang ka metsing. Likaroloana tsa colloidal li chitja ebile li na le bophara ba 6-100nm. The process of investment casting ho etsa khetla ke mokhoa oa ho gelling. Ho na le lintlha tse ngata tse susumetsang gelation, haholo electrolyte, pH, sol concentration le mocheso. Ho na le mefuta e mengata ea lisebelisoa tsa silika tsa khoebo, 'me e sebelisoang haholo ke alkaline silica Sol e nang le silica content ea 30%. E le ho hlōla mefokolo ea potoloho e telele ea ho etsa likhetla tsa khetla ea silica sol, silika e omisang kapele e entsoe lilemong tsa morao tjena. Mokhoa oa ho etsa silika sol shell o batla o le bonolo. Ts'ebetso e 'ngoe le e' ngoe e na le mekhoa e meraro: ho koahela, ho etsa lehlabathe le ho omisa. Mokhoa o mong le o mong o phetoa ka makhetlo a mangata ho fumana khetla ea multilayer ea botenya bo hlokahalang.

Ts'ebetsong ea ho etsa likhetla tsa silika, ho omisa ke ts'ebetso ea bohlokoa ka ho fetisisa. Ka ho omisa, metsi aa fetoha, li-gel tsa silica sol, le likaroloana tsa refractory li kopantsoe ka thata, kahoo li fumana khetla e matla haholo. Ena ke tokiso e ntle bakeng sa ho lahla ho latelang.

Ho lahla ho fumanoeng ke mokhoa oa ho etsa likhetla tsa silica sol ho na le mafika a tlase, ho nepahala ho phahameng le potoloho e telele ea ho etsa likhetla. Ts'ebetso ena e sebelisoa haholo ha ho etsoa li-alloys tse thibelang mocheso o phahameng oa mocheso, litšepe tse sa keneleng mocheso, litšepe tse sa hloekang, litšepe tsa carbon, li-alloys tse tlase, li-alloys tsa aluminium le li-alloys tsa koporo.

The silika sol ho nepahala lahlehileng boka dipeeletso tsa tshebetso e loketse bakeng sa repeatable tlhahiso ealikarolo tsa ho lahla sebopeho sa netho tsoa mefuteng e fapaneng ea litšepe tse fapaneng le lisebelisoa tse phahameng tsa ts'ebetso. Le hoja ka kakaretso e sebelisetsoa ho etsa lintho tse nyenyane, mokhoa ona o sebelisitsoe ho hlahisa liforeimi tse feletseng tsa mamati a lifofane, tse nang le litšepe tse fihlang ho 500 kgs le aluminium ea ho fihla ho 50 kgs. Ha ho bapisoa le mekhoa e meng ea ho lahla joalo ka lefu kapaho lahla lehlabathe, e ka ba ts'ebetso e theko e boima. Leha ho le joalo, likarolo tse ka hlahisoang ka tšebeliso ea matsete li ka kenyelletsa li-contours tse rarahaneng, 'me maemong a mangata likarolo li lahleloa haufi le sebopeho sa marang-rang, kahoo ha li hloke ho tsosolosoa hanyenyane kapa ho se be teng hang ha ho etsoa.
