Izindaba

Isidingo sezimpushana zensimbi sikhuphuke kakhulu eminyakeni yamuva nje, siqhutshwa yintuthuko ekukhiqizeni okungeziwe, izindiza, izimoto kanye neminye imboni ehlukahlukene. Izimpushana zensimbi zibalulekile ezinqubweni ezifana nokunyathelisa kwe-3D, ukuthungwa kwensimbi kanye nokusansimbi kwempushana. Enye yezindlela eziphumelela kakhulu zokukhiqiza lezi zimpushana ngokusebenzisa i-atomization yempushana yensimbi, inqubo eguqula insimbi encibilikisiwe ibe yizinhlayiya ezincane. Lesi sihloko sihlola indlela insimbi eguqulwa ngayo ibe yimpushana, sigxile endimeni yemishini yokwenza i-atomization yempushana kule nqubo ebalulekile yokukhiqiza.

Qonda i-atomization yempuphu yensimbi

I-atomization yempuphu yensimbi inqubo eguqula insimbi encibilikisiwe ibe yizinhlayiya zempuphu ecolekile. Lobu buchwepheshe buthandwa ngenxa yekhono labo lokukhiqiza izinhlayiya ezinobukhulu bezinhlayiya obufanayo, ukuma kanye nokusatshalaliswa, okubaluleke kakhulu ezinhlotsheni ezahlukene zokusebenza. Inqubo ye-atomization ingahlukaniswa cishe ngezinhlobo ezimbili eziyinhloko: i-atomization yegesi kanye ne-atomization yamanzi.

Ukwenziwa kwegesi

Ekufakweni kwegesi, insimbi encibilikisiwe ithululwa nge-nozzle bese ifakwa i-atomized ngomfudlana wegesi onesivinini esikhulu, ngokuvamile i-nitrogen noma i-argon. Ukupholisa okusheshayo kwamaconsi ancibilikisiwe kuphumela ekwakhekeni kwezinhlayiya zensimbi eqinile. Le ndlela isebenza kahle kakhulu ekukhiqizeni impuphu ehlanzekile kakhulu ngoba igesi engasebenzi kahle inciphisa i-oxidation kanye nokungcola.

Ukwenziwa kwe-atomization yamanzi

Ngakolunye uhlangothi, i-atomization yamanzi isebenzisa amajethi amanzi anomfutho ophezulu ukuphula insimbi encibilikisiwe ibe amaconsi. Le ndlela ngokuvamile ingabizi kakhulu futhi ingakhiqiza inani elikhulu lempuphu. Kodwa-ke, ingabangela i-oxidation ethile, engathinta ukusebenza komkhiqizo wokugcina. I-atomization yamanzi ivame ukusetshenziselwa ukukhiqiza i-iron powder, kuyilapho i-gas atomization ikhethwa kakhulu kwizinsimbi ezingezona i-ferrous kanye nama-alloy.

Inqubo yokwenza i-atomization ye-metal powder

Inqubo yokuguqula insimbi ibe yimpuphu ngokusebenzisa i-atomization ihilela izinyathelo eziningana ezibalulekile:

Ukuncibilikisa InsimbiIsinyathelo sokuqala ukuncibilikisa insimbi noma i-alloy esithandweni somlilo. Lokhu kungenziwa kusetshenziswa izindlela ezahlukene, okuhlanganisa ukuncibilikisa i-induction, ukuncibilikisa i-arc noma ukuncibilikisa ukumelana. Ukukhetha indlela yokuncibilikisa kuncike ohlotsheni lwensimbi kanye nezakhiwo ezifiselekayo zempuphu yokugcina.

Ukwenziwa kwe-atomization: Ngemva kokuba insimbi incibilikisiwe, idluliselwa ekamelweni le-atomization. Kuleli gumbi, insimbi encibilikisiwe ifakwa igesi enomfutho ophezulu noma amajethi amanzi, okuyephula ibe amaconsi amancane. Ubukhulu bamaconsi bungalawulwa ngokulungisa ingcindezi kanye nesivinini sokugeleza kwe-medium ene-atomized.

Ukupholisa Nokuqinisa: Amaconsi ayaphola futhi aqine ngokushesha njengoba edlula egumbini lokufafaza. Izinga lokupholisa libalulekile njengoba lithinta isakhiwo esincane kanye nezakhiwo zempuphu ephumayo. Izinga lokupholisa okusheshayo ngokuvamile likhiqiza izinhlayiya ezincane kanye nesakhiwo esincane esifanayo.

Ukuqoqwa Nokuhlukaniswa: Ngemva kokuqina, impuphu yensimbi iyaqoqwa futhi ihlukaniswe ngokosayizi wezinhlayiya. Lokhu kuvame ukwenziwa kusetshenziswa amasu okuhlola noma okuhlukanisa umoya. Umkhiqizo wokugcina ungacutshungulwa okwengeziwe, njengokugaya noma ukuxuba, ukuze kutholakale ukusatshalaliswa kosayizi wezinhlayiya ofiselekayo kanye nezakhiwo.

Ngemva kokucutshungulwa: Kuye ngokusetshenziswa, izimpushana zensimbi zingadinga ukucutshungulwa okwengeziwe, njengokufakwa kobuso noma ukwelashwa kokushisa, ukuze kuthuthukiswe izakhiwo zazo. Lesi sinyathelo sibalulekile ukuqinisekisa ukuthi impushana ihlangabezana nezidingo ezithile zokusetshenziswa okuhlosiwe.

Umsebenzi wedivayisi yokwenza i-powder atomization

Imishini yokwenza i-powder atomization iyisikhungo esiklanyelwe ngqo ukwenza inqubo yokwenza i-powder yensimbi ibe ngephumelelayo nangendlela efanele. Lawa mafektri ahlonyiswe ngobuchwepheshe obuthuthukisiwe kanye nemishini ukuqinisekisa ukukhiqizwa kwe-powder esezingeni eliphezulu. Nazi ezinye izingxenye ezibalulekile kanye nezici zedivayisi yokwenza i-powder atomization:

1.Isithando Somlilo

Inhliziyo yanoma iyiphi imishini yokwenza i-powder atomization yi-furnace. Yakhelwe ukuphatha izinsimbi nezinhlobo ezahlukene ze-alloy, lawa ma-furnace ahlinzeka ngokulawula izinga lokushisa okunembile ukuqinisekisa izimo zokuncibilika ezifanele. Ama-furnace okungenisa asetshenziswa kabanzi ngenxa yokusebenza kahle kwawo kanye nekhono lawo lokuncibilikisa izinto eziningi ezahlukene.

2.Uhlelo Lokwenza I-Atomization

Izinhlelo ze-atomization zibalulekile ekukhiqizeni izimpushana zensimbi ezisezingeni eliphezulu. Lokhu kufaka phakathi amakamelo okufafaza, ama-nozzle, kanye nezinhlelo zokulethwa kwegesi noma amanzi. Uhlelo lwe-atomization oluthuthukisiwe lwenzelwe ukuthuthukisa usayizi wamaconsi kanye nokusatshalaliswa kwawo, ukuqinisekisa izakhiwo zempushana ezifanayo.

3.Uhlelo Lokupholisa Nokuqoqa

Ngemva kokwenziwa kwe-atomization, izinhlelo zokupholisa nezokuqoqa zidlala indima ebalulekile ekubambeni i-powder eqinile. Lezi zinhlelo zivame ukufaka ama-cyclone, izihlungi nama-hopper ukuze kuhlukaniswe i-powder kwi-atomizing media bese ziyiqoqa ukuze icutshungulwe kabanzi.

4.Ukulawulwa Kwekhwalithi Nokuhlolwa

Ukulawulwa kwekhwalithi kubalulekile ekukhiqizweni kwempuphu.Izitshalo zokwenziwa kwe-powder atomizationngokuvamile banezindawo zokucwaninga ezizinikele ukuhlola izakhiwo zomzimba nezamakhemikhali zama-powder abawakhiqizayo. Lokhu kufaka phakathi ukuhlaziywa kosayizi wezinhlayiya, ukuhlolwa kwesimo kanye nokuhlaziywa kokwakheka kwamakhemikhali ukuqinisekisa ukuthi i-powder ihlangabezana nezindinganiso zemboni.

5.Izinhlelo Zokuzenzakalela Nokulawula

Izitshalo zesimanje ze-atomization yempuphu zihlonyiswe ngezinhlelo ezithuthukisiwe zokwenza izinto ngokuzenzakalelayo kanye nokulawula ezingaqapha futhi zilawule yonke inqubo yokukhiqiza. Lokhu kuqinisekisa ukuvumelana, kunciphisa amaphutha abantu, futhi kwandisa ukusebenza kahle okuphelele.

Ukusetshenziswa kwempuphu yensimbi

Izimpushana zensimbi ezikhiqizwa nge-atomization zinezindlela eziningi zokusebenza ezimbonini ezahlukene:

Ukukhiqiza Okungeziwe: Izimpushana zensimbi zibalulekile kubuchwepheshe bokuphrinta be-3D, okuvumela ukukhiqizwa kwamajiyometri ayinkimbinkimbi kanye nezakhiwo ezilula.

Izindiza: Izimpushana zensimbi ezisebenza kahle zisetshenziswa ezingxenyeni zezindiza lapho isilinganiso samandla nesisindo kanye nokumelana nezimo ezimbi kakhulu kubalulekile.

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

Amadivayisi Ezokwelapha: Izimpushana zensimbi ezihambisana ne-biocompatible zisetshenziselwa ukukhiqiza izifakelo kanye ne-prosthetics ukuqinisekisa ukuphepha nokusebenza kahle.

Amathuluzi kanye nama-Dies: Izimpushana zensimbi nazo zisetshenziswa ekukhiqizeni amathuluzi kanye nama-dies, okunikeza ubulukhuni obudingekayo kanye nokumelana nokuguguleka.

Ekuphetheni

Ukuguqula insimbi ibe yimpuphu ngokusebenzisa i-atomization kuyinqubo eyinkimbinkimbi edlala indima ebalulekile ekukhiqizeni kwesimanje. Izitshalo zokwenziwa kwe-atomization yempuphu ziphambili kulobu buchwepheshe, zihlinzeka ngengqalasizinda edingekayo kanye nobuchwepheshe bokukhiqiza izimpuphu zensimbi ezisezingeni eliphezulu zezinhlelo zokusebenza ezahlukahlukene. Njengoba imboni iqhubeka nokukhula futhi idinga izinto ezithuthukisiwe kakhulu, ukubaluleka kokwenziwa kwe-atomization yempuphu yensimbi kuzokhula kuphela, kuvuleke indlela yokusungula izinto ezintsha ekukhiqizeni kanye nesayensi yezinto. Kungakhathaliseki ukuthi ukukhiqizwa kwezindiza, izimoto noma okwengezwayo, ikusasa lezimpuphu zensimbi liqhakazile, liqhutshwa amakhono ezitshalo zokwenziwa kwe-atomization yempuphu.
