Izindaba

Isidingo sezimpushana zensimbi siye sakhula eminyakeni yamuva nje, siqhutshwa intuthuko kwezokukhiqiza, indawo yezindiza, ezezimoto nezinye izimboni ezihlukahlukene. Izimpushana zensimbi zibalulekile ezinqubweni ezifana nokuphrinta kwe-3D, i-sintering kanye ne-powder metallurgy. Enye yezindlela eziphumelela kakhulu zokukhiqiza lezi zimpushana iwukuba i-atomization ye-metal powder, inqubo eguqula insimbi encibilikisiwe ibe yizinhlayiya ezinhle. Lesi sihloko sihlola ukuthi insimbi iguqulwa kanjani ibe yimpushana, igxile endimeni yemishini ye-atomization ye-powder kule nqubo yokukhiqiza ebalulekile.

Qonda i-metal powder atomization

I-atomization ye-Metal powder iyinqubo eguqula insimbi encibilikisiwe ibe yizinhlayiya zempushana. Ubuchwepheshe buvunywa ikhono labo lokukhiqiza izimpushana ezinosayizi wezinhlayiyana ezifanayo, ukuma nokusabalalisa, okubalulekile ekusetshenzisweni okuhlukahlukene. Inqubo ye-atomization ingahlukaniswa cishe ngezinhlobo ezimbili eziyinhloko: i-atomization yegesi kanye ne-atomization yamanzi.

I-atomization yegesi

Ku-atomization yegesi, insimbi encibilikisiwe ithululwa nge-nozzle futhi ifakwe i-athomu umfudlana wegesi onesivinini esikhulu, ngokuvamile i-nitrogen noma i-argon. Ukupholisa okusheshayo kwamaconsi ancibilikisiwe kubangela ukwakheka kwezinhlayiya zensimbi eziqinile. Le ndlela iphumelela kakhulu ekukhiqizeni izimpushana ezihlanzeke kakhulu ngoba igesi engenzi lutho inciphisa i-oxidation nokungcola.

I-atomization yamanzi

I-atomization yamanzi, ngakolunye uhlangothi, isebenzisa amajethi amanzi anengcindezi ephezulu ukuze aphule insimbi encibilikisiwe ibe amaconsi. Le ndlela ngokuvamile iyonga kakhulu futhi ingakhiqiza inani elikhulu lempushana. Nokho, kungase kubangele i-oxidation ethile, engathinta ukusebenza komkhiqizo wokugcina. I-atomization yamanzi ivame ukusetshenziselwa ukukhiqiza impushana yensimbi, kuyilapho i-atomization yegesi ikhethwa ezinsimbi ezingenayo insimbi nama-alloys.

Inqubo ye-atomization ye-Metal powder

Inqubo yokuguqula insimbi ibe yimpushana ngokusebenzisa i-atomization ihilela izinyathelo ezimbalwa ezibalulekile:

Ukuncibilikisa Insimbi: Isinyathelo sokuqala ukuncibilikisa insimbi noma ingxubevange esithandweni somlilo. Lokhu kungenziwa kusetshenziswa izindlela ezahlukahlukene, okubandakanya ukuncibilika kokungeniswa, ukuncibilika kwe-arc noma ukuncibilika kokumelana. Ukukhethwa kwendlela yokuncibilika kuncike ohlotsheni lwensimbi kanye nezakhiwo ezifunwayo ze-powder yokugcina.

I-Atomization: Ngemva kokuba insimbi incibilikile, idluliselwa ekamelweni le-atomization. Kuleli gumbi, insimbi encibilikisiwe ingaphansi kwegesi ephezulu yokucindezela noma ijethi yamanzi, ihlephule ibe amaconsi amancane. Ubukhulu bamaconsi bungalawuleka ngokulungisa ingcindezi kanye nezinga lokugeleza kwe-atomized medium.

Ukupholisa kanye Nokuqinisa: Amaconsi ayapholisa futhi aqine ngokushesha njengoba edlula egumbini lokufutha. Izinga lokupholisa libalulekile njengoba lithinta i-microstructure kanye nezakhiwo zempushana ewumphumela. Amazinga okupholisa asheshayo ngokuvamile akhiqiza izinhlayiya ezicolekile kanye ne-microstructure efanayo.

Ukuqoqwa nokuhlukaniswa: Ngemva kokuqiniswa, i-powder yensimbi iqoqwa futhi ihlukaniswe ngokuvumelana nosayizi wezinhlayiyana. Lokhu kuvame ukwenziwa kusetshenziswa izindlela zokuhlola noma zokuhlukanisa umoya. Umkhiqizo wokugcina ungacutshungulwa okwengeziwe, njengokugaya noma ukuhlanganisa, ukuze uthole ukusabalalisa usayizi wezinhlayiyana oyifunayo kanye nezakhiwo.

Ngemuva kokucubungula: Kuye ngesicelo, izimpushana zensimbi zingadinga ukucutshungulwa okwengeziwe, njengokumbozwa kwendawo noma ukwelashwa kokushisa, ukuze kuthuthukiswe izakhiwo zazo. Lesi sinyathelo sibalulekile ukuqinisekisa ukuthi impushana ihlangabezana nezidingo ezithile zesicelo esihlosiwe.

Umsebenzi we-powder atomization device

Imishini ye-atomization ye-Powder iyisikhungo esiklanyelwe ngqo ukwenza inqubo ye-atomization ye-metal powder ngempumelelo nangempumelelo. Lezi zimboni zifakwe ubuchwepheshe obusezingeni eliphezulu kanye nemishini yokuqinisekisa ukukhiqizwa kwempushana kwekhwalithi ephezulu. Nazi ezinye izingxenye ezibalulekile nezici zedivayisi ye-atomization eyimpushana:

1.Isithando somlilo

Inhliziyo yanoma iyiphi i-powder atomization imishini isithando somlilo. Njengoba iklanyelwe ukuphatha izinhlobonhlobo zezinsimbi nama-alloys, lezi ziko zinikeza ukulawula okunembayo kwezinga lokushisa ukuze kuqinisekiswe izimo zokuncibilika ezifanele. Izithando ze-induction zisetshenziswa kabanzi ngenxa yokusebenza kahle kwazo kanye nekhono lokuncibilikisa izinhlobonhlobo zezinto.

2.Isistimu ye-Atomization

Izinhlelo ze-atomization zibalulekile ekukhiqizeni izimpushana zensimbi ezisezingeni eliphezulu. Lokhu kuhlanganisa amagumbi okufutha, imibhobho, namasistimu okulethwa kwegesi noma amanzi. Isistimu ye-atomization ethuthukisiwe yakhelwe ukuthuthukisa usayizi wamaconsi kanye nokusatshalaliswa, iqinisekisa izici zempushana ezifanayo.

3.Ukupholisa kanye nohlelo lokuqoqa

Ngemuva kwe-atomization, ukupholisa nokuqoqa izinhlelo zidlala indima ebalulekile ekubambeni impushana eqinile. Lawa masistimu ngokuvamile ahlanganisa ama-cyclone, izihlungi nama-hoppers ukuze ahlukanise impushana kumidiya ye-atomizing futhi ayiqoqe ukuze iqhubeke nokusebenza.

4.Ukulawula Ikhwalithi Nokuhlola

Ukulawulwa kwekhwalithi kubalulekile ekukhiqizeni impushana.Izitshalo ze-atomization ye-Powderngokuvamile babe namalabhorethri azinikele ukuhlola izici ezingokomzimba nezamakhemikhali zezimpushana abazikhiqizayo. Lokhu kuhlanganisa ukuhlaziywa kosayizi wezinhlayiyana, ukuhlolwa kokuma kwemvelo kanye nokuhlaziywa kokwakheka kwamakhemikhali ukuze kuqinisekiswe ukuthi impushana ihlangabezana namazinga embonini.

5.Amasistimu wokuzenzakalela nokulawula

Izitshalo zesimanje ze-atomization yempushana zifakwe ezishintshayo ezithuthukile kanye nezinhlelo zokulawula ezingaqapha futhi zilawule yonke inqubo yokukhiqiza. Lokhu kuqinisekisa ukungaguquguquki, kunciphisa iphutha lomuntu, futhi kwandise ukusebenza kahle okuphelele.

Ukusetshenziswa kwe-metal powder

Izimpushana zensimbi ezikhiqizwe yi-atomization zinezinhlobonhlobo zezicelo ezimbonini ezahlukahlukene:

Ukukhiqiza Okungeziwe: Izimpushana zensimbi zibalulekile kubuchwepheshe bokuphrinta be-3D, okuvumela ukukhiqizwa kwejometri eyinkimbinkimbi nezakhiwo ezingasindi.

I-Aerospace: Izimpushana zensimbi ezisebenza kahle zisetshenziswa ezingxenyeni ze-aerospace lapho isilinganiso samandla nesisindo kanye nokumelana nezimo ezibucayi kubalulekile.

Ezezimoto: Izimpushana zensimbi zisetshenziselwa ukukhiqiza izingxenye zenjini, amagiya nezinye izingxenye ezibalulekile ezidinga ukunemba okuphezulu nokuqina.

Amadivayisi Ezokwelapha: Izimpushana zensimbi ze-Biocompatible zisetshenziselwa ukwenza izimila kanye nama-prosthetics ukuqinisekisa ukuphepha nokusebenza kahle.

Amathuluzi kanye Dies: Izimpushana zensimbi nazo zisetshenziselwa ukukhiqizwa kwamathuluzi futhi ziyafa, zinikeze ubulukhuni obudingekayo nokumelana nokugqoka.

Ekuphetheni

Ukuguqula insimbi ibe yimpushana nge-atomization kuyinqubo eyinkimbinkimbi edlala indima ebalulekile ekukhiqizeni kwesimanje. Izitshalo ze-atomization ze-Powder zihamba phambili kulobu buchwepheshe, zinikeza ingqalasizinda edingekayo kanye nobuchwepheshe bokukhiqiza izimpushana zensimbi ezisezingeni eliphezulu zezinhlelo zokusebenza ezihlukahlukene. Njengoba imboni iqhubeka nokuthuthuka futhi idinga izinto ezithuthuke kakhulu, ukubaluleka kwe-atomization ye-metal powder kuzokhula kuphela, kuvula indlela yokuqamba okusha ekukhiqizeni nakwisayensi yezinto ezibonakalayo. Noma ngabe i-aerospace, ukukhiqizwa kwezimoto noma okungeziwe, ikusasa lezimpushana zensimbi liqhakazile, liqhutshwa amandla ezitshalo ze-atomization yempushana.
