Kuponyera ndalama, komwe kumadziwikanso kuti kuponya phula, ndi nkhungu ya sera yopangidwa ndi sera kuti aponyedwe m'zigawo, ndiyeno nkhunguyo imakutidwa ndi matope, yomwe ndi nkhungu yamatope. Pambuyo kuyanika dongo nkhungu, sungunulani mkati sera nkhungu m'madzi otentha. Chikombole chadongo cha phula losungunuka chimachotsedwa ndikuwotchedwa mu mbiya. Akawotcha. Kawirikawiri, popanga matope, chipata chimasiyidwa, ndiyeno zitsulo zosungunuka zimatsanuliridwa pachipata. Pambuyo pozizira, zitsulo zofunikira zimapangidwira.

Mibadwo yam'mbuyomu yoyika ndalama:

Mawu ofunikira: owononga nthawi komanso okwera mtengo

Kuponya ndalama kumatchedwanso kutaya phula. Njira yotaya sera ku China idayamba mu Nyengo ya Spring ndi Yophukira ndipo ili ndi mbiri yayitali.

Kutaya phula ndi phula lopangidwa ndi phula loti lidzaponyedwa m'zigawo zina, ndiyeno ndondomeko ya serayo imakutidwa ndi matope, yomwe ndi ndondomeko yamatope. Pambuyo kuyanika dongo nkhungu, sungunulani mkati sera nkhungu m'madzi otentha. Chikombole chadongo cha phula losungunuka chimachotsedwa ndikuwotchedwa mu mbiya.

Masitepe opangira ndalama zosindikizira za 3D akufotokozedwa pansipa.

Masitepe asanu ndi atatu a 3D kusindikiza ndalama zosindikizira:

1. CAD Modelling, 3D Printing Lost Foam

Mafayilo a digito amtundu woyengedwa woyengedwa amapangidwa pogwiritsa ntchito mapulogalamu a CAD, kenako amatumizidwa kunja. Mtundu wa STL ndi kusindikizidwa pogwiritsa ntchito chosindikizira cha 3D (ukadaulo wa SLA ndiwovomerezeka pa chosindikizira cha 3D). Ntchito yosindikiza nthawi zambiri imatenga maola ochepa okha.

2. Yang'anani ngati pali mabowo muzojambula zosungunula.

Kupukuta pamwamba ndi ntchito zina pambuyo pokonza ikuchitika pa 3D kusindikizidwa chitsanzo kuchotsa pamwamba lamination. Kenako yang'anani mosamala ngati chitsanzocho chili ndi ming'alu kapena ming'alu.

3. Kuphimba pamwamba

Pamene chitsanzocho chimatumizidwa ku maziko, pamwamba pa chitsanzocho choyamba chimakutidwa ndi matope a ceramics slurry. Chigawo cha slurry chiyenera kugwirizanitsidwa kwambiri ndi chitsanzo choponyera ndalama, ndipo ubwino wa slurry wosanjikiza umakhudza mwachindunji khalidwe lapamwamba la kuponya komaliza.

4. Kuwombera zipolopolo

Pambuyo popaka matope a ceramic, gawo lakunja la matope a ceramic ndi mchenga wa viscous. Pambuyo kuyanika, bwerezani masitepe a ❖ kuyanika slurry ndi kukakamira mchenga mpaka chipolopolo chifike pa makulidwe omwe mukufuna.

5. Kuwotcha ndi kuyeretsa

Chigobacho chikawuma, chimayikidwa mu ng'anjo ndikuwotchedwa mpaka zonse zosungunula zomwe zili mkatimo zipse. Panthawiyi, chipolopolocho chidzakhala zitsulo zonse chifukwa cha kutentha. Pambuyo pa kuchotsedwa mu ng'anjo, mkati mwa ng'anjoyo iyenera kutsukidwa bwino ndi kutsuka, kenaka zowuma ndi kutenthedwa.

6. Kuponya

Pogwiritsa ntchito kutaya, kupanikizika, vacuum suction ndi mphamvu ya centrifugal, zitsulo zamadzimadzi zosungunuka zimadzazidwa ndi chipolopolo chopanda kanthu ndikuzizizira.

7. Kuwonetsera

Pambuyo pazitsulo zamadzimadzi zitakhazikika ndikupangidwa, chipolopolo cha ceramic kunja kwa chitsulo chimatsukidwa ndi kugwedezeka kwa makina, kuyeretsa mankhwala kapena kutulutsa madzi.

8. Pambuyo pokonza

Kulondola kwazithunzi, kachulukidwe ndi zida zina zamakina amitundu yazitsulo zimathanso kuyesedwa ndi chithandizo chapamtunda kapena kukonza makina.

Chosindikizira cha SLA 3D cha SHDM chitha kugwiritsidwa ntchito kupanga nkhungu zapulasitiki pogwiritsa ntchito fusible komanso kutentha kwambiri. Ndizoyenera kwambiri kuponyera magawo ndi njira yotayika sera.

Pambuyo kusindikiza nkhungu pulasitiki anamaliza, ndi yotsalira ufa particles adzachotsedwa, ndiyeno sera kulowerera adzagwiritsidwa ntchito kuonetsetsa kuti nkhungu pulasitiki chatsekedwa ndi woyera kusintha khalidwe la ndalama kuponyera mbali.

Njira yochiritsira yotsatirayi ndi yofanana ndi njira yopangira chikhalidwe: choyamba, zokutira za ceramic zimakutidwa pamwamba pa nkhungu ya pulasitiki, ndiyeno imayikidwa mu uvuni.

Pamene kutentha kuposa 700 C, nkhungu pulasitiki amayaka kwathunthu popanda zotsalira, amenenso chiyambi cha dzina la sera imfa njira.

Kusindikiza kwa 3D kumatha kuzindikira mapangidwe ovuta kwambiri, ndikupanga ndalama zopangira ndalama mwachangu, mophweka komanso mwachuma. Amagwiritsidwa ntchito kwambiri pamagalimoto, zodzikongoletsera, kupanga makina ndi mafakitale ena.
