Ukukhetha i- i-wax engcono kakhulu yefekthri yokuphonsa i-wax elahlekile ukusebenza akukhona mayelana nokuthola inketho eshibhile-imayelana nokususa amaphuzu okuhluleka afihliwe ngaphambi kokuba afinyelele esithandweni somlilo. Sibone ukukhiqizwa okuningi kungasebenzi esigabeni sokukhathala ngenxa yezinsalela ze-wax ezivala amaphaseji amahle endaweni yephampu ye-cobalt alloy. Abanye balahle u-30% wenqwaba ngemva kokuqhekeka kwegobolondo—balandelelwa emuva ekwandiseni okushisayo okungahambisani ngesikhathi sokukhishwa kwe-waxing. Lezi akuzona izingozi zethiyori. Ziyizindleko zansuku zonke ngesikhathi, izinto ezibonakalayo, nokwethenjwa kwekhasimende.
Kungani ama-Wax Ajwayelekile Ehluleka Ngaphansi Kwesidingo Sezimboni
Amafekthri amaningi aqala ngama-wax e-investment ajwayelekile adizayinelwe ubucwebe noma ukukhishwa kwe-aluminium enengcindezi ephansi. Lokho kuyasebenza—kuze kube usebenzisa imizimba ye-AMS 5387 cobalt alloy alloy ku-1,550°C noma imibhobho esekelwe ku-T800 edinga ukulawulwa kobukhulu obungu-±0.05 mm ezigabeni zodonga ezingu-0.8 mm. Ama-wax ajwayelekile awanazo izici ezintathu okungaxoxiswana ngazo: ukushiswa okungenamlotha okunembile ngaphansi kuka-650°C, i-zero surface tack ngemva kokudilizwa, kanye nokuncipha kokushisa okungaphansi kuka-0.45% ukusuka ku-25°C kuya ku-60°C. Ngaphandle kwawo, uthola amadiphozithi ekhabhoni acekela phansi isiphetho, ukudonsa kwesikhunta okuhlanekezela ama-flange amancane, noma imifantu emincane kumagobolondo e-ceramic ngesikhathi sokuphuma kwe-steam.
Sahlola amawaksi ayisikhombisa ezimboni phakathi nezinyanga ezingu-18—kuhlanganise nezingxube ezimbili zobunikazi—ezingxenyeni zangempela zokukhiqiza: izindlu zamasilinda ephampu ye-piston, amavalvu omfutho we-hydraulic, nama-winch center shaft roller. Bathathu kuphela abaphumelele ukuqinisekiswa komjikelezo ogcwele. Umdlali osezingeni eliphezulu wayengeyona i-wax ephezulu kakhulu yokuncibilika. Bekuyilona elinobubanzi obuqinile bokuqina (52–54°C), i-viscosity ephansi kakhulu ku-65°C (8,200 cP), kanye nezinsalela zomlotha eziqinisekisiwe ezingaphansi kuka-0.003% ngemva kokutubeka okungu-620°C/2-ihora nge-ASTM F2897 ngayinye.
Imibandela Emine Yobuchwepheshe Ayikho Imboni Okufanele Yeqe
Khohlwa izimangalo zokumaketha. Nakhu okubalulekile uma ufanelekile ukukhishwa kwe-wax ekusetshenzisweni kokutshalwa kwezimali kobuqotho obuphezulu:
- Ukuzinza kwe-Dimensional post-injection: I-wax kufanele ibambe ukubekezelela kwe-GD&T ngokupholisa—ngisho nasezinxenyeni ezingafani ne-asymmetric ezifana nezisekelo zephampu ezinobude obungu-220 mm kanye nogqinsi lwedonga elingu-3.2 mm. Sikala ukushwabana ngamaphoyinti amathathu: umnyombo, udonga olumaphakathi, nonqenqema lwe-flange. Ukuchezuka okwamukelekayo: ≤0.38% inani loshintsho lomugqa.
- Ukuhambisana kwe-Dewaxing: I-steam dewaxing idinga ukuncibilika ngokushesha, okuphelele ngaphandle kokuvuvukala noma amabhamuza. Ama-wax ane->0.8% yama-fatty acids mahhala abe negwebu ngaphansi kwesitimu esigcwele—okubangela ukubola kwegobolondo. Iphasi eliqinisekisiwe: ayikho insalela ebonakalayo eziteshini zokupholisa zangaphakathi ezingu-3 mm ngemva kwemizuzu engu-12 yomjikelezo wesitimu ongu-160°C.
- Ukulawula ukunamathela kweShell: Ukunamathela kakhulu kubangela ukuphuka kwegobolondo ngesikhathi sokuphatha. Okuncane kakhulu kubangela ukususwa kwe-slurry. Amandla afanele we-wax ebusweni: 34–36 mN/m ku-30°C—akalwa nge-contact angle goniometry, hhayi ukuqagela kwedatha.
- Umkhawulo wokusebenziseka kabusha: I-wax egaywe kabusha incipha ngokushesha kumafrakshini aguquguqukayo. Silandelela ukwehla kwephoyinti elikhanyayo kanye nokukhuphuka kwenombolo ye-asidi. Umkhawulo wokusebenzisa kabusha: imijikelezo engu-3 enkulu uma inombolo ye-asidi ihlala <0.8 mg KOH/g kanye nephoyinti elikhanyayo lihlala lingu-≥110°C.
Indlela QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Iqinisekisa Ukusebenza Kwe-Wax
Esikhungweni sethu esithobela i-ISO e-Qingdao, ukufaneleka kwe-wax akuwona umsebenzi walebhu—isango lokukhiqiza. Yonke i-wax entsha yenza izivivinyo ezine ngesikhathi esisodwa:
- Isivivinyo esinezingxenye ezingu-50 sengxenye yangempela yekhasimende: Ipulaki ye-cobalt alloy AMS 5387 enokubekezela okungu-0.5 mm kweradial ku-12 mm OD.
- Isilinganiso se-CMM ngaphambi nangemva kokukhipha inwaxa ukuze kulinganiswe ukuhlanekezela kwephethini.
- Ukuhlaziywa kwe-Thermogravimetric (TGA) kwezinsalela zokushiswa ezisekelweni zensimbi engagqwali—kuqinisekiswe ngokumelene nemephu eyisisekelo ye-SEM-EDS.
- Ukuguga okusheshisiwe: amahora angama-72 ku-40°C/85% RH, kulandelwa amandla aqinile nokuhlolwa kwe-elongation nge-ASTM D638 ngayinye.
Le nqubo ibambe i-wax eyodwa ehlangabezana nawo wonke amashidi e-specpe-kodwa yehlulekile ukuhlolwa #2. I-coefficient yayo yokunweba okushisayo ikhuphuke ngaphezu kuka-85°C, okubangele ukwehla okungu-0.12 mm ehlombe elivalekayo elibalulekile. Leyo ngxenye yayingaphumelela ekuhlolweni okubukwayo kodwa yavuza ezindaweni ezingu-350 enkonzweni yasensimini. Asithumeli imibono. Sithumela idatha.
Ukukhetha I-Wax Yakho: Izinyathelo Ezilandelayo Ezisebenzayo
Ungathembeli kumasampula omphakeli wodwa. Qalisa lolu hlu lokuhlola ngaphambi kokuphothula olwakho i-wax engcono kakhulu yefekthri yokuphonsa i-wax elahlekile ukukhetha:
- Cela amajika e-TGA aphelele—hhayi nje izimangalo “ezingenamlotha”. Funa isisindo sensalela % ku-550°C, 600°C, naku-650°C.
- Hlola i-dewaxing kusistimu yakho yegobolondo okuyiyonayona: i-binder efanayo, i-stucco efanayo, ishejuli yokomisa efanayo. I-wax elungele amagobolondo e-silica sol ingase yehluleke ngokuyinhlekelele nge-colloidal zircon.
- Qinisekisa amapharamitha womjovo emishinini yakho: izinga lokushisa le-nozzle, isivinini sokugcwalisa, ingcindezi yephakethe. Ukushintsha okungu-2°C kwezinga lokushisa elincibilikayo kungashintsha ubuhwaba bendawo i-Ra ngo-0.4 µm—okwanele ukuthi kuthinte ukumanzisa kwe-ceramic slurry.
- Idinga ukulandeleka kwenqwaba: inombolo yenqwaba, izitifiketi zezinto ezingavuthiwe, nemibiko ye-QC efana ne-oda lakho lokuthenga. Akukho okuhlukile.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imithombo yama-wax aqinisekisiwe ahlangabezana nale mikhawulo yokukhiqiza kwayo—futhi yabelana ngephrothokholi yokuqinisekisa ephelele nozakwethu abaqeqeshiwe. Ngoba ukusebenza kwe-wax okungaguquki akusona isikhungo sezindleko. Ungqimba lokuqala lobuqotho bobukhulu bayo yonke i-valve yokucindezela, yonke indlu yephampu, yonke ingxenye ye-cobalt alloy eyakhelwe ukusinda ekucindezelekeni komhlaba wangempela.
Bheka ngale kwephuzu lokuncibilika. Kala ukushwabana. Landelela izinsalela. Qinisekisa ku-geometry yakho. Yileyo ndlela oyeka ngayo ukujaha amaphutha okusakaza-bese uqala ukuthumela izingxenye ezisebenzayo.
