Zida zoponyera sera zotayika si bokosi lina laluso - ndi mlatho weniweni pakati pa kujambula lingaliro ndikugwira mphete yomalizidwa yachitsulo m'manja mwanu. Tidawona oyambitsa akutsegula zida izi akuyembekezera matsenga, kungotsitsa mtundu wawo wachitatu wolephera 2 koloko m'mawa, ndikudabwa chifukwa chake sprue idasweka, chifukwa chiyani nkhungu idasweka, kapena chifukwa chake silivayo idakana kuyenda. Kukhumudwa kumeneko kutha pano. Izi si chiphunzitso. Ndi zomwe tidawona m'mizere 47 yofananira ndi ophunzira opanga zodzikongoletsera, okonda kuchita masewera olimbitsa thupi, ndi oyambitsa ma studio ang'onoang'ono - nthawi iliyonse ndikuyeretsa pakati pa kupezeka ndi kukhulupirika kwazitsulo.
Chifukwa chiyani "woyamba" Sikutanthauza "Kusokoneza"
A zoona zida zoponyera phula zotayika kwa obwera kumene akuyenera kuthana ndi mavuto atatu osayanjanitsika: kukana kwamphamvu kwamafuta muzachuma, kutsimikizika kwamphamvu kwa sera, komanso kukhazikika kwapakatikati mwa kuzizira. Ma kits ambiri amalumphira mapepala azinthu zonse - kulemba "ndalama zotengera pulasitala" osatchula kutsata kwa ASTM C22 kapena ISO 6872. Zathu zimatero. Ufa wotsutsa umakwaniritsa zofunikira za ISO 6872 Type IV, ndi mphamvu yobiriwira ya ≥12 MPa ndi kuwonjezereka kwa kutentha ≤0.15% pa 700 ° C. Nambala imeneyo ndiyofunikira: ndi kusiyana pakati pa chibowo choyera ndi nkhungu yokhotakhota yomwe imatsekera thovu la mpweya pafupi ndi bezel.
Tinayesa mawonekedwe asanu ndi limodzi a sera mbali ndi mbali. Sera za microcrystalline zokhazikika zofewa pansi pa 45°C—osakhazikika kuti zisamveke bwino. Chidacho chimagwiritsa ntchito kusakaniza kwaumwini ndi 58% sera, 32% carnauba, ndi 10% dammar resin-kusungunuka kwambiri pa 63 ° C, kugwira mizere yabwino pansi pa 0.3 mm, ndikuwotcha bwino pa 650 ° C popanda zotsalira za carbon. Mudzawona izi mukamatsegula botolo lanu loyamba: palibe mwaye wakuda womamatira pamwamba pa siliva, palibe chifukwa cha pickling mwaukali.
Zomwe zili Mkati-ndi Zomwe Sizibisika mu Kusindikiza Kwabwino
Ili si bokosi la malonjezo osamveka bwino. Chigawo chilichonse chimagwira ntchito yotsimikiziridwa:
- Zida zosema sera (zidutswa 5): Carbide-nsonga, osati chitsulo chosapanga dzimbiri-chifukwa nsonga zofewa zimafowoka pa sera yolimba, zomwe zimayambitsa macheza omwe amafanana ndikujambula kwanu komaliza.
- Ufa wa ndalama (1 kg): Zosakanizidwa kale, zosefedwa, zoyendetsedwa ndi chinyezi mpaka ± 0.5% RH-palibe zongoyerekeza zosakanikirana; ingowonjezerani madzi osungunuka pa 22 ° C
- Botolo la vacuum (2L): Thupi lagalasi la Borosilicate lokhala ndi gasket la silikoni lovotera 90 kPa - ndilofunika kwambiri pochotsa mpweya wotsekeka m'mabowo ovuta
- Mbiri ya ng'anjo yoyaka moto: Kukonzekera kokonzekera 3-siteji (kuyanika → kukhetsa → sintering) kutsimikiziridwa kuti kuthetseratu kusweka kwa kutentha mu flasks
- Crucible & tongs: Silicon carbide-lined, yovotera 1100 ° C - imagwira siliva wonyezimira, mkuwa, ndi bronze popanda zowononga chitsulo
Akusowa? "Silver ingot yoyambira." Zabwino. Siliva weniweni amasungunuka pa 961 ° C - koma oyamba kumene sapeza kutentha kosasinthasintha kochepera 1050 ° C. Popanda pyrometry yeniyeni, amapeza porosity kapena kutsekedwa kozizira. M'malo mwake, zidazo zimaphatikizapo ma ingots oyesa amkuwa. Master fluidity ndi nkhungu mudzaze ndi mkuwa poyamba. Kenako onjezerani.
Bottleneck Yeniyeni Si Luso-Ndi Njira Yowonekera
Ena angatsutse kuti kusindikiza kwa digito kwa 3D kumapangitsa sera yotayika kuti isagwire ntchito. Koma izi ndi zomwe tidayezera pakugwiritsa ntchito situdiyo kwenikweni: Kwa mphete zosachepera 8 zokhala ndi mbiri yofananira, mawonekedwe a utomoni osindikizidwa a 3D amafunikira 37% yochulukirapo kuposa phula losema pamanja. Chifukwa chiyani? Mizere yosanjikiza ya 0.05 mm ya resin imapanga tinthu tating'onoting'ono tomwe timagwira zinthu zopukutira, kukakamiza nthawi yayitali komanso kutayika kwachitsulo kwambiri.
Kusema kwa manja kumaphunzitsa kulinganiza, kugawa kulemera, ndi kusokoneza malo - luso lopanda mapulogalamu odulira mapulogalamu. Ndipo chitsanzo choyamba cha sera cha wophunzira chikakomoka panthawi yotopa, amaphunzira za makulidwe a khoma ndi phula (osachepera 6 mm), osati kungogunda "kusindikiza." Kuyankha kwa tactile sikungalowe m'malo. Tinapanga buku la malangizo mozungulira molephera - osati masitepe. Tsamba 12 silimanena kuti "attach sprue." Imati: "Ngati sprue wanu wadumpha podzaza botolo, yang'anani kutentha kwa sera (kuyenera kukhala> 50 ° C) ndi m'mimba mwake (≥2.5 mm kwa mphete)."
Kuchokera Botolo Loyamba Kufikira Zodzikongoletsera Zogwira Ntchito—Palibe Kusunga Zipata
Izi zida zoponyera phula zotayika imatengera ziro zomwe zidachitika kale-koma sizilolera njira zazifupi. Zimaphatikizapo hygrometer yolinganizidwa chifukwa chinyezi choposa 60% RH chimapangitsa kuti ndalama zikhazikike mwachangu, ndikutsekereza mpweya. Imatumiza ndi 0.01 mm dial caliper-osati monga mwanaalirenji, koma chifukwa chakuti makulidwe a ring shank pansi pa 1.2 mm amalephera kuyesedwa kwamphamvu pa 120 N. Manambala amenewo sakhala opondereza. Amatengedwa kuchokera ku ASTM F2590 (miyezo yolimba ya zodzikongoletsera) ndipo amatsimikiziridwa mu malo athu ovomerezeka a ISO 9001 ku Qingdao-kumene timaponyera nyumba zopangira mafuta akunyanja pogwiritsa ntchito chemistry yofananira komanso ma vacuum protocol.
Simukugula zida zamasewera. Mukupeza njira zoyendetsera ntchito zamafakitale, zochepetsedwa popanda kuchepetsedwa. Ma nozzles omwewo a cobalt-alloy omwe timapangira makina opangira ma hydraulic amadalira kuwongolera komweko kwamafuta, ma kinetics akuwotcha omwewo, malingaliro ofanana a nkhungu. Kulondola sikungosungidwira makontrakitala a madola miliyoni. Zimayambira pomwe sera yanu imakumana ndi ndalama.
Yambani ndi sera. Lemekezani mayendedwe otopa. Khulupirirani opanda kanthu. Ponyani mphete yanu yoyamba - osati monga chizolowezi, koma ngati umboni kuti kuwongolera kumayamba kalekale chitsulo chisanadutse.
