Iyo abantu benshi bumvise 'silica sol precision casting', bashushanya ibintu bitagira inenge, net-shusho, biteguye kugenda. Nibyo byiza byo kwamamaza. Ukuri, gusya burimunsi, ni imishyikirano ihoraho hamwe na chimie ya colloidal, ikoreshwa rya stucco, hamwe na fiziki itababarira yo gukomera kwicyuma. Ntabwo ari ugukora ifu gusa; bijyanye na injeniyeri by'agateganyo, ceramic-lined cavity yitwara neza byateganijwe munsi ya 1500 ° C icyuma gishongeshejwe. Amaduka menshi arakosorwa kurwego rwanyuma - birakomeye, byanze bikunze - ariko uko mbibona, intambara nyayo iratsindwa cyangwa igatsindwa mucyumba cyihuta ndetse na autoclave ya dewaxing. Aho niho geometrie yabitswe cyangwa igoretse mbere yuko igitonyanga kimwe cyicyuma gisukwa.
Ibitekerezo Byibanze: Nibihuza gusa
Benshi bafata silika sol nka kole yoroshye, ihuza gufata ifu yangiritse hamwe. Ibyo birenze urugero. Ni gahunda nzima. Ibicuruzwa bya sol, pH, na SiO2 ntabwo ari imibare gusa kurupapuro rwihariye; bategeka uburyo ikote rya mbere ihanagura ibishashara, uko bingana, kandi amaherezo, hejuru yubuso bwa casting. Nabonye ibyiciro aho sol yari 'ishaje' gato, biganisha kumagambo yihuta hamwe na Ethyl silicate ikomeye. Igisubizo? Ikoti ryibanze ryacitse mikoro yacitse mugihe cyo kwangiza, itera inenge zifata kuri buri mukinnyi wiruka. Icyuma cyari cyiza 316L, ariko ibice byari bishaje.
Aha niho uburambe bwibanze bwabatanga ibintu. Ukeneye umufatanyabikorwa wunvise ko ibikoreshwa byihariye nkibikorwa. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu mugushushanya no gushora imari, ibona ibi imbere. Ntabwo ari ukugurisha silika sol gusa; ni ukumenya ko intsinzi yawe silika sol inzira ihagaze kumurongo wamazi. Ibikorwa byabo byigihe kirekire byerekana kumenyera byimbitse, bifatika hamwe nibi bintu bifatika, ubwoko buturuka gusa kumirongo yumusaruro uko umwaka utashye.
Guhitamo ifu yangiritse - silika ihujwe, zircon, cyangwa ikindi kintu nka mullite - yashakanye nimyitwarire ya sol. Zircon ikenera ubukonje butandukanye butandukanye na silika yahujwe kugirango ibe nziza. Ni uguhuza. Ntushobora guhitamo imwe mu bwigunge. Ibi twabyize inzira igoye kumushinga wa turbine blade prototype. Twahinduye ifu nziza ya zircon kugirango tumenye neza kubyara ariko dukomeza ibipimo byo kwibiza kimwe. Igicucu cyari kinini cyane, inguni zabaye ikiraro, kandi igikonoshwa cyateje imbere imbaraga nke. Igikonoshwa cyakomeje kuvunika mugihe cyo gukora. Isomo rihenze mubitekerezo bya sisitemu.
Imbyino yo Kwubaka Igikonoshwa: Umurongo-ku-Kwiyunga
Kubaka igikonoshwa niho ibitekerezo bihura nukuri kwuzuye mububiko. Igitabo kivuga amakoti 7-9. Ariko kubice byibyuma byibyuma? Urashobora gukenera amakoti menshi yinyuma kugirango imbaraga, ariko buri kote yongerera ibyago byo kugwa mumitego mugihe cyumye. Kubice bikikijwe cyane, bigoye cyane ibyuma, urashobora gushyira imbere amakoti make, meza kugirango wirinde kuzuza ibisobanuro. Nubwumvikane hagati yicyatsi kibisi, cyoroshye, nukuri kwanyuma.
Kuma hagati yamakoti niyo ihindagurika cyane. Ntabwo ari igihe gusa; byerekeranye no gutembera kwumwuka, ubushuhe, hamwe nubushyuhe buringaniye mubyuma. Inyandiko ntoya irashobora gutuma uruhande rumwe rwa cluster rwuma vuba, biganisha kumaganya atandukanye. Twigeze kugira ikibazo cyisubiramo hamwe nigikonoshwa cyacitse kuruhande rumwe rwumye. Yadutwaye ibyumweru kugirango tuyisubize kuri HVAC yatangaga ikirere-kirere. Gukosora ntibyari muburyo bworoshye; byari mu micungire yikigo.
Kwinangira ni ubundi buhanzi. Ingano nubwoko bwa stucco - na none, zircon, silika yahujwe, alumino-silikate - byerekana igikonoshwa no kurwanya ibyuma byinjira. Nibyiza cyane, kandi uniga guhunga gaze mugihe cyo gusuka, biganisha kuri gaze ya gaz muri casting. Birakabije, kandi ubona ubuso bwimbere bushobora gutera ibyuma byinjira no kurangiza nabi. Kubushyuhe bwo hejuru QSY Urutonde, nka nikel ishingiye kuri nikel hamwe na cobalt ishingiye ku mavuta, ifite ingingo zo gushonga cyane hamwe n’amazi atandukanye, ingamba za stucco zishobora guhinduka kugirango habeho kwangirika kwinshi no kurwanya ubushyuhe bwumuriro. Ubunararibonye bwabo murwego runini rwibintu, kuva ibyuma gushiramo ibyuma bidasanzwe, bivuze ko bagomba kumenya neza ibyo bahinduye.
Dewaxing: Akanya-Stress Akanya
Nibizamini byambere byukuri bya shell yawe. Ibyo byose byitondewe bigiye gukorerwa kwaguka byihuse mugihe ibishashara bishonga kandi bikaguka. Umuvuduko wa autoclave hamwe nubushyuhe bwo kuzamuka ni ngombwa. Byihuta cyane, kandi umuvuduko wa hydraulic wibishashara uzavunika nigikonoshwa cyubatswe neza. Biratinda cyane, kandi ushobora gukuramo ibishashara bituzuye, biganisha kumuriro nubusembwa bwa karubone mugihe cyo gutwika.
Twari dufite igice cyibishishwa kumibiri ya valve yahoraga isatura munsi yisoko. Igikonoshwa cyasaga neza. Twagenzuye ibintu byose - guhubuka, gukama, stucco. Hanyuma, twarebye ibishashara ubwabyo. Umutanga mushya yari afite coefficient yo hejuru gato yo kwagura ubushyuhe. Igikonoshwa, cyagenewe ibishashara bishaje byo kwagura ibishashara, ntibishobora kubamo umuvuduko winyongera. Igisubizo kwari uguhindura autoclave cycle, mugutangiza akanya gato mbere yumuvuduko kugirango woroshye ibishashara mbere yigiturika nyamukuru. Yongeyeho iminota 3 kuri cycle ariko ikiza ibihumbi.
Gutwika & Gusuka: Aho Ceramic Shell Yinjiza Igumana
Gutwika ntabwo ari ugutwika gusa ibishashara. Nibijyanye no gucumura ceramic, guteza imbere imbaraga zayo zanyuma. Igicucu kigera kuri 1000 ° C + kigomba kugenzurwa kugirango wirinde guhungabana. Carbone isigaye yose ivuye mu gishashara irashobora gukora ikirere kigabanya imbere mugikonoshwa, kuri bimwe bivangwa nkibikoresho bimwe na bimwe bitagira umwanda, birashobora kwangiza chimie yubutaka.
Hanyuma haza gusuka. Aha niho igikonoshwa cyinjira ni ngombwa. Icyuma gishongeshejwe gitemba, imyuka igomba guhunga ikoresheje urukuta rw'igikonoshwa. Niba igikonoshwa ari cyinshi (uhereye hejuru cyane cyangwa stucco nziza), gaze iragwa, ikora pinholes. Ndibuka akazi kubatwara pompe muri duplex ibyuma bidafite ibyuma. Igikonoshwa cyari cyiza, cyuzuye, kandi gikomeye. Ariko twari dufite igipimo cya 30% cyo kwangwa kuri gaze yo hejuru. Ikibazo cyakomotse kuri kote ya gatatu n'iya kane, twari tumaze gusya igihe gito kugirango ituze, bituma iba nziza cyane kandi igabanya imyenge hagati. Urubanza rusanzwe rwo kunoza imitungo imwe (gutuza buhoro) ku kiguzi cyingirakamaro (permeability).
Kurangiza & Ibipimo-byukuri
Icyemezo kiri mucyumba cyo gusya. Ni bangahe bigomba gukurwaho? Byakozwe neza silika sol inzira igomba gutanga ibice bisaba kurangiza bike. Ahantu ho gukuraho amarembo hagomba kuba hasukuye, ntugashwanyaguze igice kinini. Ubuso bugomba kuba bufite isuku ihagije kuburyo kubantu bamwe badakomeye, guturika kwikirahure-isaro birahagije. Iki nigiciro kinini cyo kuzigama, cyane cyane kumavuta akomeye nka cobalt-ishingiye kuri mashini.
Iyi ni serivisi ihuriweho na serivise yuzuye itanga. Ntabwo ari ugukora igikonjo no gusuka ibyuma. Nibintu byose byuruhererekane, kuva muburyo bwo gukora kugeza kurangiza Imashini ya CNC. Urebye QSYIngano - ikubiyemo ibishushanyo mbonera, gushora imari, hamwe no gutunganya CNC - byubatswe kugirango bigenzure uru rugendo rwose. Barashobora gushushanya uburyo bwo gukina bakoresheje imashini mubitekerezo, bagahindura ahantu h'irembo kugirango hasukure bike, ninyungu nini kubintu bigoye. Urubuga rwabo, https://www.tsingtaocnc.com, yerekana ubu buryo bwahujwe, kubashyira nkigisubizo cyibice byarangiye, ntabwo ari ibishishwa gusa.
Mugusoza, silika sol precision casting ni urunigi rwibyemezo ijana bito. Buri kimwe - kuva kuri pH ya sol kugeza ku gipimo cyo hejuru mu itanura ryaka - gisiga igikumwe ku gice cya nyuma. Amaduka atsinze ntabwo akurikiza resept gusa; barimo gusoma ibishishwa, basobanura ibice, kandi bahora bahindura inzira. Nuruvange rwibikoresho byimbitse siyanse hamwe nintoki, hafi ya intuitive, ubukorikori bwo hasi. Intego ntizigera itungana; birahanurwa, bisubirwamo byiza, icyiciro nyuma yicyiciro. Kandi ibyo biva gusa mugihe cyo mu myobo, guhangana nubushyuhe bwigihe cyimvura cyangwa igice gishya cyumucanga wangiritse witwara ukundi.
