Iindaba

I-Metal powders inoluhlu olubanzi lwezicelo kwiinkalo ezahlukeneyo, ezifana ne-aerospace, ukuveliswa kweemoto, ushicilelo lwe-3D, njl. Njengesixhobo esiphambili sokwenza umgubo wentsimbi,izixhobo zesinyithi umgubo atomizationubukhulu becala iqinisekisa ukufana kobungakanani besuntswana lomgubo ngezi ndlela zilandelayo.

1,Lungiselela iiparamitha zenkqubo ye-atomization

1.Uxinzelelo lwe-atomization

Uxinzelelo lwe-atomization yenye yezinto ezibalulekileyo ezichaphazela ukufana kwepowder particle size. Ukunyusa ngokufanelekileyo uxinzelelo lwe-atomization kunokwaphula ukuhamba kwamanzi esinyithi kumasuntswana acolekileyo, okukhokelela kumasuntswana omgubo ocolekileyo. Okwangoku, uxinzelelo lwe-atomization oluzinzile lunokuqinisekisa ukuhlukana okuhambelanayo kokuhamba kolwelo lwetsimbi ngexesha lenkqubo ye-atomization, enceda ukuphucula ukufana kobungakanani bepowder. Ngokulawula ngokuchanekileyo uxinzelelo lwe-atomization, uhlengahlengiso olusebenzayo lwe-powder particle size lunokufezekiswa.

2.Ubushushu bokuhamba kwesinyithi

Iqondo lokushisa lokuhamba kwesinyithi libuye libe nefuthe elibalulekileyo kwi-particle size ye powder. Xa iqondo lokushisa liphezulu kakhulu, i-viscosity ye-metal liquid iyancipha, i-tension surface iyancipha, kwaye kulula ukwenza iinqununu ezinkulu; Xa iqondo lobushushu liphantsi kakhulu, ulwelo lwesinyithi luwohloka, olungeyomfuneko kwi-atomization. Ngoko ke, kuyimfuneko ukukhetha ubushushu obufanelekileyo bokuhamba kwesinyithi ngokwezinto ezahlukeneyo zetsimbi kunye neenkqubo ze-atomization ukuqinisekisa ukufana kobungakanani bepowder.

3.Isakhiwo sombhobho weAtomization

Uyilo lwesakhiwo sombhobho we-atomizing ihambelana ngokuthe ngqo kwimpembelelo ye-atomization ye-metal liquid flow. Ulwakhiwo lombhobho olufanelekileyo lunokwenza ukuba ulwelo lwesinyithi luqukuqele enze amathontsi afanayo ngexesha lenkqubo ye-atomization, ngaloo ndlela kufumaneke umgubo onobungakanani bamasuntswana afanayo. Umzekelo, ukusebenzisa imilomo ye-atomizing enamanqanaba amaninzi kunokuphucula ukusebenza kakuhle kwe-atomization kwaye wenze ubungakanani besuntswana elingumgubo lifane ngakumbi. Ukongeza, iiparamitha ezinje ngokuvula umlomo, imilo, kunye ne-engile nazo kufuneka ziphuculwe kwaye ziyilwe ngokweemfuno ezithile zemveliso.

2,Lawula ngokungqongqo umgangatho wemathiriyeli ekrwada

1.Ukucoceka kwezixhobo zetsimbi

Ukucoceka kwezinto eziluhlaza zetsimbi kunempembelelo enkulu ekufaniseni ubungakanani bepowder particle. Izinto ezicocekileyo zetsimbi ezicocekileyo zinokunciphisa ubukho bokungcola, ukunciphisa ukuphazamiseka kokungcola kwinkqubo ye-atomization, kwaye ngaloo ndlela kuphuculwe ukufana kobungakanani bepowder. Kwinkqubo yokuvelisa, ukucoceka okuphezulu kunye nozinzile izinto zetsimbi ezisemgangathweni kufuneka zikhethwe, kwaye uvavanyo olungqongqo kunye nokuhlolwa kufuneka kuqhutywe kubo.

2.Ubungakanani besuntswana lezinto zentsimbi

Ubungakanani bamasuntswana ezinto ezikrwada zetsimbi bunokuchaphazela ukufana kobungakanani besuntswana lomgubo. Ukuba ubungakanani bamasuntswana ezinto eziluhlaza zetsimbi abulingani, umahluko obonakalayo kubungakanani bamasuntswana unokwenzeka ngexesha lokunyibilika kunye neenkqubo ze-atomization. Ngoko ke, kuyimfuneko ukulungiselela kwangaphambili izinto eziluhlaza zetsimbi ukwenza ubungakanani bamasuntswana bufanane kangangoko kunokwenzeka. Ukugaya, ukuhlolwa kunye nezinye iindlela zingasetyenziselwa ukucubungula izinto zetsimbi zokuphucula umgangatho wazo.

3,Ukomeleza ukugcinwa nokulawulwa kwezixhobo

1.Ukucoca izixhobo

Coca rhoqo iumgubo wentsimbi atomizationizixhobo zokususa uthuli, ukungcola, kunye neentsalela ngaphakathi kwesixhobo ukuqinisekisa ukusebenza kwayo okuqhelekileyo. Ngokukodwa kumacandelo abalulekileyo afana ne-atomizing nozzles, ukucocwa rhoqo kunye nokugcinwa kuyadingeka ukukhusela ukuvinjelwa kunye nokugqoka, ukuqinisekisa ukuzinza kwempembelelo ye-atomization.

2.Ulungelelwaniso lwezixhobo

Rhoqo ukulinganisa izixhobo ze-atomization zetsimbi kwaye ukhangele ukuba iiparitha ezahlukeneyo zezixhobo ziyahlangabezana neemfuno. Umzekelo, ukukhangela ukuchaneka kwezixhobo ezifana ne-atomization yoxinzelelo kunye nezivamvo zobushushu, ukulungelelanisa indawo kunye ne-angle ye-nozzles, njl. Ngokusebenzisa ukulinganisa izixhobo, ukuzinza kunye nokuthembeka kwezixhobo ngexesha lenkqubo yokuvelisa kunokuqinisekiswa, kunye nokufana kwezixhobo. Ubungakanani besuntswana lomgubo lunokuphuculwa.

3.uqeqesho lwabasebenzi

Ukubonelela ngoqeqesho lobuchwephesha kubasebenzi ukuphucula izakhono zabo zokusebenza kunye nolwazi olusemgangathweni. Abaqhubi kufuneka baqhelane neenkqubo zokusebenza kunye neeparitha zenkqubo yesixhobo, kwaye bakwazi ukuchonga ngokukhawuleza nokusombulula iingxaki kwinkqubo yokuvelisa. Ngexesha elifanayo, kuyimfuneko ukuqinisa ulawulo lwabaqhubi, ukuseka inkqubo yokuhlola engqongqo, kunye nokuqinisekisa ukulinganisa kunye nokuqhelekileyo kwenkqubo yokuvelisa.

4,Ukwamkela itekhnoloji yokufumanisa ephucukileyo

1.Uhlalutyo lwamasuntswana eLaser

I-Laser particle size analyzer sisixhobo sokubona ubungakanani besuntswana esetyenziswa ngokuqhelekileyo esinokukhawuleza nangokuchanekileyo ukulinganisa ubungakanani besuntswana losasazo lomgubo. Ngokuqhuba ixesha langempela lokubeka iliso kwipowder ngexesha lenkqubo yokuvelisa, kunokwenzeka ukuqonda ngexesha elifanelekileyo utshintsho kwi-powder particle size, ukuze ulungelelanise iiparitha zenkqubo kunye nokuqinisekisa ukufana kwe-powder particle size.

2.Uhlalutyo lwe-electron microscopy

I-electron microscopy inokwenza uhlalutyo lwe-microscopic ye-morphology kunye nesakhiwo se-powder particles, ukunceda abaphandi baqonde inkqubo yokuqulunqa kunye neempembelelo ezichaphazelayo ze powders. Ngokusebenzisa uhlalutyo lwe-electron microscopy, izizathu zokungalingani kobungakanani be-powder particle zingachongwa, kwaye amanyathelo ahambelanayo anokuthathwa ukuze aphuculwe.

Ngamafutshane, ukuqinisekisa ukufana kobungakanani besuntswana lomgubo kwisixhobo sesinyithi se-atomization kufuna imiba emininzi, njengokuphucula iiparamitha zenkqubo ye-atomization, ukulawula ngokungqongqo umgangatho wezinto ezikrwada, ukomeleza ukugcinwa kwezixhobo kunye nolawulo, kunye nokwamkela itekhnoloji yokubona ephambili. Kuphela ngokuqwalasela ngokubanzi le miba kunye nokuvuselela ngokuqhubekayo kunye nokuphucula iteknoloji sinokuvelisa i-powders yesinyithi kunye nobukhulu obufanayo be-particle kunye nomgangatho ozinzile, ukuhlangabezana neemfuno zesicelo semimandla eyahlukeneyo.
