Tinene zoona, anthu ambiri akamva za 'silica sol investment casting', amajambula ma injini a jet opanda chilema kapena zojambulajambula zovuta kwambiri. Ndiyo mbali ya kukongola. Chowonadi, kugaya tsiku ndi tsiku, ndi kupanga chipolopolo chodalirika chomwe sichimang'ambika, kugwa, kapena kusunga phulusa lambiri, pazigawo zomwe nthawi zambiri siziwoneka. Ndi njira yomwe binder - silica sol - ndi chirichonse ndipo palibe kanthu panthawi imodzi. Zamatsenga sizili mu silika ya colloidal yokha, koma momwe mumakwatirana ndi stucco, malo owuma, komanso moona mtima, momwe mumayendera zomwe mukuyembekezera. Mashopu ambiri amaganiza kusintha a silika sol Investment casting ndondomeko ndi kukweza kwachindunji kwa chirichonse. Si. Ndi chida, ndi finicky pa izo.
Pakatikati pa Chipolopolo: Kuposa Binder Yokha
Ndikukumbukira pamene tidasintha mizere ina kuchokera ku ethyl silicate kupita ku silica sol. Malonda a malonda anali okhudza kutha kwabwinoko komanso mphamvu zobiriwira zambiri. Chimene sanagogomeze mokwanira chinali kuwongolera nyengo. Ndi ethyl silicate, muli ndi mwayi. Ndi silica sol, malo anu oyanikapo amakhala gawo lofunikira kwambiri. Chinyezi ndi kayendedwe ka mpweya sizongolimbikitsa; iwo amalamula mlingo wa gelation wa sol. Kuthamanga kwambiri, ndipo mumapeza chovala cha nkhope chophwanyika, chong'ambika. Kuchedwetsa kwambiri, ndipo kupanga kwanu kumayima.
Tinaphunzira izi movutikira pamagulu a ma valve kwa kasitomala. Mapeto ake anali okongola, kulondola kwake kunali kowonekera, koma tinali ndi chiwopsezo cha 30% cha kulephera kwa zipolopolo panthawi ya dewaxing. Zipolopolozo zinkawoneka bwino. Nkhani yake? Tinali ndi chinyontho, ndipo malaya oyambilira anali asanagwere bwino tisanagwiritse malaya osungira. Panthawi ya autoclave dewaxing, kuthamanga kwa nthunzi kunapeza zigawo zofooka, zozungulira pang'ono. Zotsatira zake zinali zoopsa kwambiri kuti zigoba zing'ambika, osati ngalande zaukhondo zomwe timafunikira. Sikunali kulephera kwakuthupi; chinali njira yolephera kudziwa.
Ndipamene ukatswiri weniweni wagona-osati kugula silika sol, koma kumanga dongosolo mozungulira izo. Ndiko kudziwa kuti ufa wa zircon wa malaya oyamba umafunika sol yosinthidwa ndi pH kuposa yomwe mungagwiritse ntchito popanga malaya a aluminosilicate a stucco. Ndi chemistry yokhazikitsidwa pamlingo wa mafakitale.
Kumene Kumawaliradi (ndipo Kumene Sikukuwalira)
Chifukwa cha zovuta zake zonse, silika sol Investment casting sichingagonjetsedwe pazinthu zina. Ganizirani zigawo zopyapyala, ndime zovuta zamkati, kapena ma aloyi omwe amagwira ntchito kwambiri. Chipolopolo cha monolithic ceramic chomwe mumapeza kuchokera ku silika sol yopangidwa bwino ndi yowuma kwambiri komanso yosasunthika. Timagwiritsa ntchito pafupifupi ntchito yathu yotentha kwambiri ya alloy-based nickel ndi cobalt. Kukhazikika kwa chipolopolo pakutsanulira kutentha ndikwapamwamba, komwe kumachepetsa kuchita kwa zipolopolo zachitsulo ndikukupatsani zitsulo zoyera.
Ndimayang'ana pulojekiti yochokera kwa ogulitsa, Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), yemwe amalemba izi ngati luso lofunikira. Ndi zaka 30 akuponya ndi kupanga, mutha kubetcherana njira zawo zachitsulo chosapanga dzimbiri komanso ma aloyi apadera amatsamira kwambiri pamagetsi okhwima a silika. Sichinthu chomwe mumangokhalira kuchichita; ndi kudzipereka. Kuti mugwiritse ntchito knob yachitsulo ya kaboni kapena bulaketi yosavuta yachitsulo? Overkill. Mtengo ndi nthawi yozungulira siziyenera. ROI imabwera mukamaponya choyikapo chitsulo chosapanga dzimbiri chokhala ndi ma vanes owonda kuposa ndalama, pomwe kukhulupirika kowoneka bwino sikungakambirane.
The Machining Handshake
Iyi ndi mfundo yomwe nthawi zambiri imaphonya. The kuponya ndalama ndondomeko sikutha pa shakeout. Wopeza wabwino amaganizira za makina kuyambira pachiyambi. Chigoba cha silica sol nthawi zambiri chimatulutsa kutha kwapamwamba, komwe kumamveka bwino. Koma zimatanthauzanso kuti khungu loponyera ndi lolimba komanso lofanana. Izi zimakhudza momwe zida zanu za CNC zimagwirira ntchito ndi kudula koyamba. Tidayenera kusintha ma feed ndi njira za zida zomwe zimachokera ku mzere wa silika sol poyerekeza ndi njira zathu zina.
Ntchito yophatikizika ngati QSY, yomwe imagwira ntchito zonse zopangira zipolopolo, kuponya ndalama, ndi makina a CNC pansi pa denga limodzi, ili ndi mwayi wapadera pano. Gulu lawo lokonza makina silikulandira kuponyedwa mu bokosi lakuda; iwo akupeza gawo lomwe mbiri ya ndondomeko yomwe iwo ayenera kumvetsa. Iwo amadziwa kuti zotsalira pachipata pa silika sol kuponyera akhoza kukhala osiyana kuuma mbiri, kotero iwo akhoza kukonza CNC moyenerera. Chotsekeka chotsekeka ichi kuchokera pakuwumba mpaka kumachining ndi komwe kumamangidwa bwino komanso kuchita bwino, osati mu dipatimenti yoponya yokha.
Njere Zamchenga mu Magiya
Palibe ndondomeko yangwiro. Mutu waukulu wokhala ndi silica sol, kupatula kukhudzidwa kwa nyengo, ndikutha kwa chipolopolo. Kupsa mtima n'kofunika kwambiri. Zomangira zotsalira za silika zimatha kusiya zotsalira zagalasi, zotsalira pamalo oponyedwa, makamaka m'makona oloweranso. Iyi si njere yamchenga yosasunthika yomwe mungathe kuiphulitsa; zasakanizidwa. Nthawi ina tinali ndi gulu la nyumba zopopera pomwe zotsalira izi zidatsekeredwa mu ulusi wamkati. Zinali zovuta kukonza, pafupifupi kufuna kuchotsedwa kwa electrochemical.
Apa ndi pamene Investment in kuponya ndalama zimakhala zenizeni. Mbiri yanu ya ng'anjo yotentha kwambiri sinakhazikike ndipo iwalani. Iyenera kupangidwa mogwirizana ndi misa ya chipolopolo ndi aloyi. Kuponyera chitsulo cholemera kwambiri kumafunikira kutentha kosiyana ndi kopanda aluminiyamu yokhala ndi mipanda yopyapyala kuti zitsimikizire kuchotsedwa kwathunthu. Ndi gawo lina la kayendetsedwe ka kayendetsedwe ka ntchito komwe kumalekanitsa malo ogulitsa ntchito ndi malo opezeka bwino.
Maonedwe a Pragmatic
Ndiye, kodi silica sol ndi tsogolo? Kwa umphumphu wapamwamba, zigawo zolondola, mwamtheradi. Ndiwo msana wa zamlengalenga, zamankhwala, komanso kutulutsa kwamafakitale apamwamba. Koma si panacea wapadziko lonse. Lingaliro lakugwiritsa ntchito liyenera kukhala laukadaulo ndi malonda: kumaliza kofunikira (ma Ra values), kuyambiranso kwa alloy, gawo la geometry, ndi mtengo wovomerezeka pagawo lililonse.
Poyesa mnzanu wa ntchito yoteroyo, sikuti mukungogula zojambulazo. Mukugula zipika zawo zowongolera zachilengedwe, zolemba zawo zosamalira matope, ma chart awo otopa. Mukugula zaka zambiri zokhazikika, monga zomwe munganene kuchokera kwa wogwiritsa ntchito nthawi yayitali m'munda. Mtengo weniweni mu ndondomeko ngati silika sol Investment casting sichimayikidwa mu banki, koma mu kukumbukira kwa minofu ya amisiri ndi mainjiniya omwe adamenya nkhondo zake, adaphunzira kuchokera ku zolephera zake, ndikugwiritsa ntchito mphamvu zake zambiri kuti apange magawo omwe sangapangidwe mwanjira ina iliyonse.
