Masinyaniseke, xa abantu abaninzi besiva 'i-silica sol investment cast', bafanekisela iiblade ze-injini yejethi engenasiphako okanye amaqhekeza obugcisa antsonkothileyo. Licala lobukhazikhazi elo. Okwenyani, ukugawula kwemihla ngemihla, kumalunga nokwenza iqokobhe elithembekileyo elingaqhekeziyo, elidilikayo, okanye ligcine uthuthu oluninzi, kwiindawo ezihlala zingabonwa. Yinkqubo apho i-binder-i-silica sol-iyinto yonke kwaye akukho nto ngaxeshanye. Umlingo awukho nje kwi-silica ye-colloidal ngokwayo, kodwa kwindlela otshata ngayo kunye ne-stucco, indawo yokomisa, kwaye ngokungafihlisiyo, indlela olawula ngayo okulindelekileyo. Iivenkile ezininzi zicinga ukutshintshela kwi-a i-silica sol investment casting inkqubo luphuculo oluthe ngqo kuyo yonke into. Ayiyo. Sisixhobo, kwaye siphelile.
UMongo weShell: Ngakumbi kunesibophelelo nje
Ndikhumbula xa sasiqala ukuguqula imigca ethile ukusuka kwi-ethyl silicate ukuya kwi-silica sol. Indawo yokuthengisa yayimalunga nokugqitywa komphezulu ongcono kunye namandla aphezulu aluhlaza. Into abangazange bayigxininise ngokwaneleyo kulawulo lwemozulu. Nge-ethyl silicate, unendlela ethile. Nge-silica sol, indawo yakho yokomisa iba yiparamitha yenkqubo ebalulekileyo. Ukufuma okunxulumeneyo kunye nokuhamba komoya ayizozinto nje zokuthuthuzela; bayalela ireyithi yegelation yesol. Ukukhawuleza, kwaye ufumana idyasi yobuso e-brittle, eqhekekileyo. Ukucotha kakhulu, kwaye umjikelo wakho wemveliso uyayeka ukuma.
Oku sikufunde kabuhlungu kwibhetshi yemizimba yevalvu kumxhasi. Ukugqitywa bekumhle, ukuchaneka komda bekundawo, kodwa besine-30% yenqanaba lokungaphumeleli kweqokobhe ngexesha lokukhupha. Amaqokobhe ayekhangeleka egqibelele. Ingxaki? Sasinopelo olufumayo, kwaye iidyasi zokuqala zazingekageli ngokupheleleyo phambi kokuba sifake iidyasi ezigcinayo. Ngexesha le-autoclave dewaxing, uxinzelelo lomphunga lufumene ezo maleko abuthathaka, afakwe kancinci. Umphumo waba kukuqhekeka kweqokobhe okuyintlekele, kungekhona umsele ococekileyo esasiwufuna. Yayingekokusilela kwezinto eziphathekayo; yayiyinkqubo yokusilela kolwazi.
Kulapho ubuchwephesha bokwenyani bulele khona-hayi ekuthengeni i-silica sol, kodwa ekwakhiweni kwenkqubo ejikelezileyo. Kumalunga nokwazi ukuba umgubo we-zircon wedyasi yokuqala udinga i-sol ehlengahlengisiweyo eyahlukileyo ye-pH kunaleyo onokuyisebenzisa kwiidyasi ze-stucco zamva ze-aluminosilicate. Yikhemistri ebekwe kwinqanaba loshishino.
Apho Ikhanya ngenene (kwaye apho ingakhanyisiyo)
Kuko konke ukuphikisana kwayo, i-silica sol investment casting ayinakoyiswa kwizicelo ezithile. Cinga ngamacandelo abhityileyo, iipaseji ezintsonkothileyo zangaphakathi, okanye iialloys ezisebenza kakhulu. Iqokobhe le-ceramic le-monolithic olifumana kwinkqubo eyenziwe kakuhle ye-silica sol lixinene ngokumangalisayo kwaye liyachasa. Siyisebenzisa phantse ngokukodwa kumsebenzi wethu we-alloy high-temperature-based-nickel-based and cobalt-based stuff. Uzinzo lweqokobhe kumaqondo obushushu okugalela luphezulu, nto leyo inciphisa ukusabela kweqokobhe lesinyithi kwaye ikunike umphezulu wesinyithi ococekileyo.
Ndandijonge iprojekthi evela kumthengisi, Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), odwelisa oku njengobuchule obuphambili. Ngeminyaka yabo engama-30 ekujuleni nasekusebenzeni, ungabheja inkqubo yabo yentsimbi engatyiwayo kunye ne-alloy castings ekhethekileyo yayame kakhulu kwinkqubo ye-silica sol evuthiweyo. Asiyonto udlala kuyo; kukuzibophelela. Kwintsimbi yentsimbi yekhabhoni eqhelekileyo okanye intsimbi yentsimbi? Overkill. Iindleko kunye nexesha lomjikelo azikuthetheleli oko. I-ROI ifika xa usenza i-impeller yentsimbi engatyiwayo enevanes ezibhityileyo kunengqekembe, apho ukuthembeka kwedimensional kungaxoxiswana khona.
Ukuxhawula ngesandla ngoMachining
Le yingongoma edla ngokuphoswa. I utyalo mali inkqubo ayipheli ekushukumeni. I-Foundry elungileyo icinga malunga ne-machining kwasekuqaleni. Iqokobhe le-silica sol lidla ngokuvelisa umphezulu ocolekileyo, ovakala ulungile. Kodwa ikwathetha ukuba ulusu lokuphosa lunzima kwaye lufana. Oku kuchaphazela indlela izixhobo zakho ze-CNC ezisebenzisana ngayo nesiko lokuqala. Kuye kwafuneka silungelelanise amaxabiso okutya kunye neendlela zezixhobo zamalungu aphuma kumgca we-silica sol xa kuthelekiswa nezinye iinkqubo zethu.
Umsebenzi odityanisiweyo onje nge-QSY, ophethe zombini ukubunjwa kweqokobhe, ukuphosa utyalo-mali, kunye nomatshini we-CNC phantsi kophahla olunye, unenzuzo eyahlukileyo apha. Iqela labo lobuchwephesha alifumani bhokisi emnyama; bafumana inxalenye yembali yenkqubo abanokuthi bayayiqonda. Bayazi ukuba intsalela yesango kwi-silica sol casting inokuba neprofayile yobunzima eyahluke kancinane, ngoko ke banokucwangcisa i-CNC ngokufanelekileyo. Lo mgca uvaliweyo ukusuka ekubunjweni ukuya kwi-machining apho umgangatho wokwenyani kunye nokusebenza kakuhle kwakhiwe, kungekhona nje kwisebe lokuphosa kuphela.
Ukhozo lweSanti kwiiGeya
Akukho nkqubo igqibeleleyo. Intloko enkulu ene-silica sol, ngaphandle kobuntununtunu bemozulu, kukuvuza kweqokobhe. Ukudinwa kubaluleke kakhulu. Nasiphi na isibophelelo se-silica esishiyekileyo sinokushiya intsalela yeglasi, i-sintered kumphezulu wokujula, ngakumbi kwii-engile eziphinda zingene. Olu asilokhozo lwesanti oluxengaxengayo onokuluqhushumba; idityanisiwe. Sakhe saba nebhetshi yezindlu zempompo apho le ntsalela yayivaleleke kwimicu yangaphakathi. Yayiliphupha elibi ukulungisa, phantse kufuna ukususwa kwe-electrochemical.
Apha kulapho utyalo-mali utyalo mali iba yinyani. Iprofayile yakho yesithando somlilo ayisoseti kwaye ulibale. Kufuneka ilungelelaniswe kwi-shell shell kunye ne-alloy. I-heavy-section steel casting idinga umjikelo we-thermal owahlukileyo kune-aluminiyam enodonga oluncinci ukuze kuqinisekiswe ukususwa okupheleleyo kwe-binder. Ngomnye umaleko wolawulo lwenkqubo owahlula ivenkile yomsebenzi kwisiseko esichanekileyo.
Imbono yePragmatic
Ke, ngaba i-silica sol likamva? Ngokunyaniseka okuphezulu, amacandelo achanekileyo, ngokupheleleyo. Ngumqolo we-aerospace, ezonyango, kunye ne-high-end ye-industrial casting. Kodwa akusiyo i-panacea yendalo yonke. Isigqibo sokuyisebenzisa kufuneka sibe yisibalo sobugcisa kunye nezorhwebo: umphezulu ofunekayo (ixabiso le-Ra), i-reactivity ye-alloy, inxalenye yejometri, kunye neendleko ezamkelekileyo kwiyunithi nganye.
Xa uvavanya iqabane lomsebenzi onjalo, awuthengi nje ukuphosa. Uthenga iilogi zabo zolawulo lokusingqongileyo, iirekhodi zabo zolondolozo oluludaka, iitshathi zabo zokudinwa. Uthenga amashumi eminyaka yokuziqhelanisa emiliselwe, njengale nto unokuyichaza kumntu osebenza ixesha elide ebaleni. Ixabiso lokwenyani kwinkqubo efana i-silica sol investment casting ayifakwanga ebhankini, kodwa kwinkumbulo yezihlunu ezihlangeneyo zamagcisa kunye neenjineli eziye zasilwa amadabi ayo, zafunda kwiintsilelo zayo, zaza zasebenzisa amandla ayo amakhulu ukuvelisa iindawo ezingenakwenziwa ngenye indlela.
