Ukuhlolwa kweHermetic kwezixhobo zokuprinta ze-3D
Umgaqo wokusebenza
Xa i-metal powder laser eyenza i-powder (i-3D printing) iinxalenye ziveliswa, ihamba kunye nokuveliswa kwezinto ze-metal condensation, ezinokubangela ukungcoliseka komgubo xa kuxutywe kumgubo.Ukongeza, i-powders yesinyithi esebenzayo kunye neengqungquthela ezintle ezifana ne-aluminium kunye ne-titanium zinethuba eliphezulu lokuba ne-oxidized.Ezi powders zetsimbi eziphuncukileyo zifunxwa kumatshini wokuhlola ukwahlula nangaliphi na ixesha, kwaye ziphelele kwindawo evaliweyo yegesi engasebenziyo ngexesha lomjikelo wokuqinisekisa umxholo ophantsi weoksijini., ukuphepha i-oxidation yomgubo ocolekileyo, kunye nomgubo wesinyithi owahluliweyo ungena kwi-powder feeder ukuze isetyenziswe kwakhona.
Inkqubo yokuvelisa
Ukutsalwa kwezinto ezikrwada-ukuhluzwa-ikristale-ukwahlula-ukomisa-ukuhluza-ukupakishwa kwangaphakathi-ukupakishwa kwangaphandle
Ukutsalwa kwemathiriyeli ekrwada: Ngokwe-solubility yamacandelo ahlukeneyo kumayeza esintu aseTshayina kwizinyibilikisi, isinyibilikisi esinenyibiliko ephezulu yamacandelo asebenzayo kunye ne-solubility ephantsi yamacandelo angafunekiyo ukunyibilika ikhethiwe, kwaye indlela yokunyibilikisa amacandelo asebenzayo. ukusuka kwizicubu zezinto zonyango kuthiwa yi-solvent extraction.
Ukuhluzwa: Ukuhluzwa kubhekiselele ekusebenzeni kweyunithi yokwahlula amasuntswana ezinto eziqinileyo ezimiswe kwirhasi okanye kulwelo, kusetyenziswa izinto ezirhabaxa (isihluzi esiphakathi) ukudlula irhasi okanye ulwelo ekumisweni (isihluzi se-slurry) (i-filtrate), ukuvalela amasuntswana aqinileyo ( intsalela yesihluzi) eyehlayo hlala kwindawo yokucoca ukwenza ikeyiki yokucoca.
I-Crystallization: Xa isisombululo esishushu esishushu sipholile, ukunyibilika kwe-solute kuncipha kwaye isisombululo siba yi-supersaturated, ukuze i-solute iqhube ngendlela yeekristale.
Ukwahlukana: Ukwahlukana okomileyo nokumanzi.
Ukomisa: Sebenzisa ubushushu ukunyakamisa ukufuma (ukufuma okanye ezinye izinyibilikisi) kwimathiriyeli emanzi, kwaye usebenzise i-airflow okanye i-vacuum ukususa ukufuma okwenziwe ngumphunga ukufumana imathiriyeli eyomileyo.
Uvavanyo: Izinto eziphathekayo zihlelwa ngokobungakanani besuntswana.
Ukupakishwa: Ukugqiba ukupakisha.
Iinzuzo zemveliso
● Ivalwe ngokupheleleyo kwaye izaliswe ngegesi engasebenziyo ukuqinisekisa umxholo ophantsi we-oksijini kunye nenkqubo yokukhusela ukuqhuma.
● Ukwahlula amasuntswana amakhulu atyhidiweyo ukunika isiqinisekiso esizinzileyo senkqubo yoshicilelo.
● Ukwahlula okuqhubekayo, akuchaphazeli umsebenzi oqhubekayo womshicileli.
● Ukubuyisela ngokuzenzekelayo kunye nokubuyisela umva ngaphandle kokungenelela ngesandla ukuphepha ingozi kumzimba womntu.
● Ukurisayikilishwa okongeziweyo ukunciphisa ilahleko yezinto.
● Ngeenxalenye ezimbalwa, kulula ukuqhaqha kunye nokudibanisa, kwaye kulula ukucoca ngokucokisekileyo kunye nokunciphisa ixesha lokucoca.
● Isixokelelwano sisebenza ngendlela engangeni moya, kungekho mgubo uphumayo kunye nengxolo ephantsi.
Izinto ezisetyenziswayo
Isetyenziswa kushishino loshicilelo lwe-3D ukuqokelela, ukubuyisela kunye nokuhluza umgubo wesinyithi kwinkqubo yoshicilelo ye-3D ukuqonda ukusetyenziswa kwakhona kwemathiriyeli ekrwada.Kufanelekile ukujongwa kunye nokubuyisela umgubo wesinyithi, i-alloy powder, i-aluminium, i-titanium kunye nezinye izinto.
