Metal powders nwere a dịgasị iche iche nke ngwa dị iche iche ubi, dị ka aerospace, automotive n'ichepụta, 3D obibi akwụkwọ, wdg The uniformity nke powder urughuru size dị oké mkpa maka ndị a ngwa, dị ka ọ na-emetụta kpọmkwem arụmọrụ na àgwà nke ngwaahịa. Dị ka isi akụrụngwa maka imepụta ntụ ntụ metal,ígwè ntụ ntụ atomization akụrụngwatumadi ana achi achi uniformity nke powder urughuru size site na-esonụ ụzọ.
1,Welie paramita usoro atomization
1.Nrụgide atomization
Atomization mgbali bụ otu n'ime ihe ndị dị mkpa na-emetụta uniformity nke ntụ ntụ urughuru size. Ịbawanye nrụgide atomization nke ọma nke ọma nwere ike imebi mmiri mmiri igwe na-asọba n'ime ihe ndị dị mma, na-eme ka ụmụ irighiri ihe dị mma pụta. Ka ọ dịgodị, a ike atomization mgbali nwere ike hụ na-agbanwe agbanwe fragmentation nke metal mmiri mmiri eruba n'oge atomization usoro, nke na-enyere aka melite uniformity nke powder urughuru size. Site kpomkwem ịchịkwa atomization mgbali, irè ukpụhọde nke ntụ ntụ urughuru size nwere ike nweta.
2.Igwe na-eruba okpomọkụ
Okpomọkụ nke mgbaba ígwè na-enwekwa mmetụta dị ukwuu na nha nha nke ntụ ntụ. Mgbe okpomọkụ dị oke elu, viscosity nke mmiri mmiri ígwè na-ebelata, esemokwu elu na-ebelata, ọ dịkwa mfe ịmepụta ihe ndị buru ibu; Mgbe okpomọkụ dị oke ala, mmiri mmiri nke mmiri igwe na-emebi emebi, nke na-adịghị mma maka atomization. Ya mere, ọ dị mkpa iji họrọ kwesịrị ekwesị metal eruba okpomọkụ dị iche iche metal ihe na atomization Filiks iji hụ na uniformity nke powder urughuru size.
3.Atomization nozzle Ọdịdị
Nhazi nhazi nke nozzle atomizing na-emetụta kpọmkwem mmetụta atomization nke mmiri mmiri igwe. A ezi uche nozulu Ọdịdị nwere ike ime ka metal mmiri mmiri eruba na-etolite edo ụmụ irighiri mmiri n'oge atomization usoro, si otú inweta ntụ ntụ na edo urughuru size. Ọmụmaatụ, iji multi-ogbo atomizing nozzles nwere ike melite atomization arụmọrụ na-eme ka ntụ ntụ urughuru size ọzọ edo. Na mgbakwunye, parampat dị ka oghere nozzle, udi, na akụkụ dịkwa mkpa ka emeziwanye ya na imepụta ya dịka ihe achọrọ maka mmepụta.
2,Jikwaa nke ọma ịdị mma nke akụrụngwa
1.Ịdị ọcha nke akụrụngwa ígwè
Ịdị ọcha nke akụrụngwa ígwè nwere mmetụta dị ịrịba ama na ịdị n'otu nke nha nha ntụ ntụ. Akwa ọcha metal akụrụngwa nwere ike ibelata ọnụnọ nke adịghị, belata nnyonye anya nke adịghị na atomization usoro, ma si otú melite uniformity nke ntụ ntụ urughuru size. N'ime usoro mmepụta ahụ, a ga-ahọrọ ihe ndị dị na ígwè dị elu na-adị ọcha ma kwụsie ike, a ga-eme nyocha na nyocha siri ike na ha.
2.Oke urughuru nke igwe akụrụngwa
The urughuru size metal ngwaọrụ nwekwara ike imetụta urughuru size uniformity nke powders. Ọ bụrụ na urughuru size nke metal ngwaọrụ bụ ahaghị nhata, ịrịba ọdịiche na urughuru size yiri ka ime n'oge agbaze na atomization Filiks. Ya mere, ọ dị mkpa ka preprocess metal akụrụngwa na-eme ka urughuru size dị ka edo dị ka o kwere mee. Enwere ike iji egweri, nyocha na ụzọ ndị ọzọ iji hazie akụrụngwa igwe iji melite ogo ha.
3,Mee ka mmezi na njikwa akụrụngwa sie ike
1.Nchacha akụrụngwa
Na-ehicha ihe mgbe niilemetal ntụ ntụ atomizationakụrụngwa iji wepụ uzuzu, adịghị ọcha, na ihe fọdụrụ n'ime akụrụngwa iji hụ na ọ na-arụ ọrụ nkịtị. Karịsịa maka ihe ndị dị mkpa dị ka atomizing nozzles, a na-achọ ihicha na nhazi oge niile iji gbochie mgbochi na iyi, na-eme ka nkwụsi ike nke mmetụta atomization.
2.Nhazi akụrụngwa
Na-ahazi akụrụngwa atomization ntụ ntụ mgbe niile wee lelee ma paramita dị iche iche nke akụrụngwa dabara ihe achọrọ. Dị ka ihe atụ, ịlele izi ezi nke ngwá ndị dị otú ahụ dị ka atomization mgbali sensọ na okpomọkụ sensọ, ukpụhọde ọnọdụ na n'akuku nke nozzles, wdg Site akụrụngwa calibration, nkwụsi ike na ntụkwasị obi nke ngwá n'oge mmepụta usoro nwere ike hụ na, na uniformity nke. ntụ ntụ urughuru size nwere ike mma.
3.ọzụzụ ndị ọrụ
Nye ndị na-arụ ọrụ ọzụzụ ọkachamara ka ha kwalite nka ọrụ ha na mmata mma. Ndị na-arụ ọrụ kwesịrị ịmara usoro ọrụ na usoro nhazi nke akụrụngwa, ma nwee ike ịchọpụta ngwa ngwa ma dozie nsogbu na usoro mmepụta. N'otu oge ahụ, ọ dị mkpa iji wusie njikwa nke ndị na-arụ ọrụ ike, guzobe usoro nyocha siri ike, ma hụ na nhazi na nhazi nke usoro mmepụta ihe.
4,Ịnabata teknụzụ nchọpụta dị elu
1.Nyocha nha nke laser
Laser urughuru size analyzer bụ a na-ejikarị ntụ ntụ urughuru size nchọpụta ngwaọrụ nke nwere ike ngwa ngwa na n'ụzọ ziri ezi tụọ urughuru size nkesa nke powders. Site na-eduzi n'ezie nlekota nke ntụ ntụ n'oge mmepụta usoro, ọ ga-ekwe omume n'oge ịghọta mgbanwe na powder urughuru size, iji gbanwee usoro parameters ma hụ na uniformity nke powder urughuru size.
2.Electron microscope analysis
Electron microscopy nwere ike ime nyocha microscopic nke morphology na nhazi nke ntụ ntụ ntụ, na-enyere ndị na-eme nchọpụta aka ịghọta usoro nhazi na-emetụta ihe ndị na-emepụta ntụ ntụ. Site na nyocha eletrọnịkị microscope, enwere ike mata ihe kpatara nha nha ntụ ntụ na-enweghị isi, enwere ike iwere ihe ndị kwekọrọ na ya iji meziwanye ya.
Na nkenke, n'ịhụ na uniformity nke powder urughuru size na metal ntụ ntụ atomization akụrụngwa na-achọ multiple akụkụ, dị ka optimizing atomization usoro parameters, nditịm ịchịkwa akụrụngwa àgwà, ike akụrụngwa mmezi na njikwa, na ịmụta elu nchọpụta teknụzụ. Naanị site comprehensively na-atụle ihe ndị a na nọgidere innovating na-emeziwanye nkà na ụzụ anyị nwere ike na-emepụta metal powders na edo urughuru size na mụ mma, izute ngwa mkpa nke dị iche iche ubi.
