Kugwira ntchito kwawo kwa nthawi yayitali kumapereka chidziwitso chozama, chothandiza cha zinthu izi, zomwe zimangobwera chifukwa choyendetsa mizere yopanga chaka ndi chaka.
Kusankhidwa kwa ufa wosakanizidwa - silika wosakanikirana, zircon, kapena chinachake chonga mullite - ndi wokwatiwa ndi khalidwe la sol. Zircon imafunikira kukhuthala kosiyana ndi silika wosakanikirana kuti muviike bwino. Ndi kuwirikiza. Simungathe kukulitsa imodzi mwadzipatula. Tidaphunzira izi movutikira kwambiri pantchito yopanga ma turbine blade prototype. Tidasinthira ku ufa wonyezimira wa zircon kuti tichuluke mwatsatanetsatane koma tidasunga magawo ofanana. Dothi lotayirira linali lokhuthala kwambiri, ngodya zidalumikizidwa, ndipo chipolopolocho chidapanga madera ocheperako. Zipolopolozo zinkakhala zikung'ambika panthawi yogwira. Mfundo yokwera mtengo pamaganizidwe adongosolo.
Kuvina-Kumanga Zipolopolo: Kugwirizana Kwakusanjika-ndi-kusanjika
Kumanga chipolopolo ndipamene chiphunzitso chimakumana ndi zovuta zenizeni za malo ogulitsira. Bukuli likuti malaya 7-9. Koma pakupanga zitsulo zokhuthala? Mungafunike malaya owonjezera osungira kuti mukhale ndi mphamvu, koma chovala chilichonse chimawonjezera chiopsezo chotsekereza kupsinjika pakuwumitsa. Pazigawo zopyapyala zachitsulo zosapanga dzimbiri, mutha kuziyika patsogolo malaya ochepa kuti musadzaze zambiri. Ndi mgwirizano pakati pa mphamvu zobiriwira, permeability, ndi kulondola komaliza.
Kuyanika pakati pa malaya ndikosiyana kocheperako kwambiri. Sikuti nthawi yokha; ndi za mpweya, chinyezi, ndi kutentha mofanana m'chipinda chowumitsira. Kujambula pang'ono kungapangitse mbali imodzi ya gulu kuti iume mofulumira, zomwe zimapangitsa kuti pakhale zovuta zosiyana. Nthawi ina tinali ndi vuto lobwerezabwereza ndi chipolopolo chosweka mbali imodzi ya zowumitsa zathu. Zinatitengera milungu ingapo kuti tibwererenso kumalo otsegulira a HVAC omwe amapanga nyengo yaying'ono. Kukonza sikunali mu slurry formula; zinali mu kasamalidwe ka malo.
Stuccoing ndi luso lina. Kukula ndi mtundu wa stucco - kachiwiri, zircon, silika wosakanikirana, alumino-silicate - zimatsimikizira kulimba kwa chipolopolo ndi kukana kulowa kwachitsulo. Zabwino kwambiri, ndipo mumatsamwitsa kuthawa kwa gasi panthawi yothira, zomwe zimapangitsa kuti mpweya usavutike poponya. Zowoneka bwino kwambiri, ndipo mumapeza malo owoneka bwino amkati omwe angapangitse chitsulo kulowa ndikumaliza bwino. Kwa ma aloyi otentha kwambiri Mtengo wa QSY mindandanda, monga ma aloyi opangidwa ndi faifi tambala ndi ma cobalt, omwe amakhala ndi malo osungunuka kwambiri komanso kutulutsa kwamadzi kosiyanasiyana, njira ya stucco imatha kusintha kuti ikomere kukana kwambiri komanso kukana kugwedezeka kwamafuta. Zomwe adakumana nazo pamitundu yayikulu yotere, kuyambira chitsulo chotayidwa kupita ku ma aloyi apadera, zikutanthauza kuti adayenera kudziwa bwino zosinthazi.
Dewaxing: Nthawi Yopanikizika Kwambiri
Uku ndiye kuyesa koyamba kwa chipolopolo chanu. Kusanjikizako kosamalako kwatsala pang'ono kukulitsa kutentha pamene sera ikusungunuka ndikukula. Kuthamanga kwa autoclave ndi kuchuluka kwa kutentha ndikofunikira. Kuthamanga kwambiri, komanso kuthamanga kwa hydraulic kwa sera kumang'amba ngakhale chigoba chomangidwa bwino. Kuchedwetsa kwambiri, ndipo mutha kuchotsedwa mosakwanira sera, zomwe zimapangitsa kuti pakhale moto komanso kuwonongeka kwa kaboni panthawi yotopa.
Tinali ndi zipolopolo zamagulu ena a valve omwe amasweka nthawi zonse pamunsi pa sprue. Zipolopolozo zinkawoneka bwino. Tinayang'ana chilichonse - slurry, kuyanika, stucco. Pomaliza, tinayang'ana phula lokha. Wogulitsa watsopano anali ndi coefficient yokwera pang'ono yakukulitsa matenthedwe. Chigobacho, chopangidwira mbiri yakale ya sera, sichikhoza kukhala ndi mphamvu yowonjezereka. Njira yothetsera vutoli inali yosintha kayendedwe ka autoclave, kuyambitsa pang'ono pang'onopang'ono kuti mufewetse pakati pa sera kuphulika kwa nthunzi kusanayambe. Idawonjezera mphindi za 3 kuzungulira koma idapulumutsa masauzande mu zidutswa.
Kupsa ndi Kutsanuliridwa: Kumene Chipolopolo Cha Ceramic Chimapeza Malo Ake
Kupsa mtima sikungotengera zotsalira za sera. Ndi za sintering ceramic, kukulitsa mphamvu yake yomaliza yotentha. Njira yopita ku 1000 ° C+ iyenera kuyendetsedwa kuti musatenthedwe ndi kutentha. Mpweya uliwonse wotsalira kuchokera ku sera ukhoza kupangitsa mpweya wochepetsetsa mkati mwa chipolopolo, chomwe pazitsulo zina monga zitsulo zosapanga dzimbiri, zimatha kuwononga chemistry.
Ndiye pakubwera kutsanulira. Apa ndi pamene chipolopolocho chikhoza kutha. Chitsulo chosungunula chimalowa mkati, mpweya umayenera kutuluka kunja kwa khoma la chipolopolo. Ngati chipolopolocho ndi chokhuthala kwambiri (kuchokera pa kuviika kwambiri kapena phala losalala kwambiri), mpweya umatsekeka, ndikupanga mapini. Ndimakumbukira ntchito yopangira chopondera mu duplex zitsulo zosapanga dzimbiri. Zipolopolozo zinali zokongola, zokhuthala, komanso zamphamvu. Koma tinali ndi chiwerengero cha 30% chokana gasi wapansi. Nkhaniyi idayambika ku slurry yachitatu ndi yachinayi, yomwe tidayipukuta pang'ono kuti ikhale yokhazikika, ndikupangitsa kuti ikhale yabwino kwambiri ndikuchepetsa ma pores apakati. Mlandu wanthawi zonse wokonza malo amodzi (kukhazikika kwa slurry) pamtengo wovuta kwambiri (permeability).
Kumaliza & The Real-World Benchmark
Umboni uli mu chipinda chopera. Ndi katundu wochuluka bwanji amene ayenera kuchotsedwa? Wopangidwa bwino silika sol mwatsatanetsatane kuponyera ndondomeko iyenera kupereka magawo omwe amafunikira kumaliza kochepa. Malo ochotsera zipata ayenera kukhala oyera, osachotsa kagawo kakang'ono ka poponyera. Pamwamba payenera kukhala paukhondo kotero kuti kwa nkhope zina zosafunikira, kuphulika kwa galasi-mkanda wopepuka kumakhala kokwanira. Izi ndizopulumutsa ndalama zambiri, makamaka zotayira zolimba monga zokhala ndi cobalt zomwe ndizovuta kupanga makina.
Uwu ndi ntchito yophatikizika yomwe wopereka chithandizo chonse amabweretsa. Sikungopanga chipolopolo ndi kuthira zitsulo. Ndilo mndandanda wonse wamtengo wapatali, kuyambira kupanga mapatani mpaka komaliza CNC makina. Kuyang'ana pa Mtengo wa QSYKukula kwake - kuphatikiza kupanga nkhungu, kuyika ndalama, ndi makina a CNC - adapangidwa kuti aziwongolera kuyenda konseku. Amatha kupanga njira yopangira makinawo, kukhathamiritsa malo a zipata kuti azitsuka pang'ono, zomwe ndi mwayi waukulu pazinthu zovuta. Webusaiti yawo, https://www.tsingtaocnc.com, ikuwonetsa njira yophatikizikayi, ndikuyiyika ngati njira yothetsera zigawo zomalizidwa, osati zojambula zaiwisi zokha.
Pamapeto pake, silika sol mwatsatanetsatane kuponyera ndi unyolo wa zisankho zazing'ono zana. Iliyonse - kuchokera pa pH ya sol mpaka kuchuluka kwa ng'anjo yoyaka moto - imasiya chala chomaliza. Mashopu omwe amachita bwino samangotsatira zophikira; iwo akuwerenga zipolopolo, kutanthauzira ming'alu, ndi kumangosintha ndondomekoyi. Ndi kuphatikiza kwazinthu zakuya zasayansi ndi manja, pafupifupi mwachilengedwe, zaluso zamashopu. Cholinga si ungwiro; ndizodziwikiratu, kuchita bwino kobwerezabwereza, batch after batch. Ndipo izo zimangobwera kuchokera ku nthawi mu ngalande, kuthana ndi chinyezi cha nyengo ya monsoon kapena mchenga watsopano wa refractory womwe umachita mosiyana pang'ono.
