Metal powders ane zvakasiyana-siyana zvekushandisa munzvimbo dzakasiyana-siyana, dzakadai semhepo, kugadzira motokari, kudhinda kwe 3D, nezvimwewo. Kufanana kwehupfu hwehupfu hwakakosha kune izvi zvinoshandiswa, sezvo zvinokanganisa zvakananga kushanda uye kunaka kwechigadzirwa. Semudziyo wakakosha wekugadzira simbi poda,simbi upfu atomization midziyoinonyanya kuona kufanana kwehupfu hwehupfu kuburikidza nenzira dzinotevera.
1,Gadzirisa atomization process parameters
1.Atomization pressure
Atomization pressure ndechimwe chezvinhu zvakakosha zvinokanganisa kufanana kwehupfu particle size. Kunyatso wedzera kudzvanywa kweatomization kunogona kutyora simbi yemvura inoyerera ichipinda muzvikamu zvakatsetseka, zvichikonzera hupfu hwakatsetseka. Zvichakadaro, yakagadzika atomization kudzvanywa kunogona kuve nechokwadi kuparadzaniswa kwesimbi yemvura kuyerera panguva yeatomization process, iyo inobatsira kuvandudza kufanana kwehupfu particle size. Nekunyatso kudzora kudzvanywa kweatomization, kugadzirisa kunoshanda kweupfu particle size kunogona kuwanikwa.
2.Metal inoyerera tembiricha
Kupisa kwesimbi kuyerera kunewo kukanganisa kukuru pakukura kwehupfu. Kana kutonhora kwakanyanyisa, viscosity yesimbi yesimbi inoderera, kushushikana kwepamusoro kunoderera, uye zviri nyore kuumba zvidimbu zvakakura; Kana tembiricha yakadzikira, kuyerera kwesimbi yesimbi kunoderera, izvo zvisingaite kuti atomization. Naizvozvo, zvinodikanwa kusarudza yakakodzera simbi inoyerera tembiricha zvinoenderana neakasiyana simbi zvinhu uye atomization maitiro kuti ive nechokwadi chekufanana kwehupfu particle size.
3.Atomization nozzle chimiro
Dhizaini yedhizaini yeatomizing nozzle yakanangana neiyo atomization mhedzisiro yesimbi yemvura inoyerera. Iyo inonzwisisika nozzle chimiro inogona kugonesa iyo simbi yemvura kuyerera kuti igadzire madonhwe eunifomu panguva yeatomization process, nekudaro kuwana hupfu neuniform particle size. Semuyenzaniso, kushandisa akawanda-nhanho atomizing nozzles kunogona kunatsiridza atomization kushanda zvakanaka uye kuita hupfu particle size yunifomu. Uye zvakare, ma paramita akadai senge nozzle aperture, chimiro, uye kona inodawo kuvandudzwa uye kugadzirwa zvinoenderana nezvakada kugadzirwa.
2,Nyatsodzora kunaka kwezvinhu mbishi
1.Kuchena kwesimbi mbishi zvinhu
Kuchena kwesimbi mbishi zvinhu zvine chekuita kwakakura pakufanana kwehupfu hwehupfu. Yakanyanya kuchena simbi mbishi zvinhu zvinogona kuderedza kuvapo kwetsvina, kuderedza kupindira kwetsvina pane atomization process, uye nekudaro inovandudza kufanana kwehupfu particle size. Mukuita kwekugadzira, yakakwirira-kuchena uye yakagadzikana mhando simbi mbishi zvinhu zvinofanirwa kusarudzwa, uye kuomesesa kuyedzwa uye kuongorora kunofanirwa kuitwa pavari.
2.Particle size yesimbi mbishi zvinhu
Iyo particle size yesimbi mbishi zvinhu inogona zvakare kukanganisa particle size kufanana kwehupfu. Kana iyo particle size yesimbi mbishi zvinhu zvisina kuenzana, misiyano yakakura mukukura kwechidimbu inogona kuitika panguva yekunyunguduka uye maitiro eatomization. Naizvozvo, zvinodikanwa kufanogadzirisa iyo simbi mbishi zvinhu kuti iite saizi yavo ive yunifomu sezvinobvira. Kukuya, kuongorora uye dzimwe nzira dzinogona kushandiswa kugadzirisa simbi mbishi zvinhu kuvandudza kunaka kwazvo.
3,Simbisa midziyo yekuchengetedza uye manejimendi
1.Equipment kuchenesa
Nguva dzose kuchenesasimbi upfu atomizationmidziyo yekubvisa huruva, tsvina, uye zvisaririra mukati memidziyo kuti ive nechokwadi chekushanda kwayo. Kunyanya kune zvakakosha zvinhu zvakaita seatomizing nozzles, kuchenesa nguva dzose uye kugadzirisa kunodiwa kudzivirira kuvharika uye kupfeka, kuve nechokwadi kugadzikana kweatomization athari.
2.Equipment calibration
Gara uchigadzirisa iyo simbi poda atomization midziyo uye tarisa kana akasiyana ma paramita emidziyo achizadzisa zvinodiwa. Semuenzaniso, kutarisa kurongeka kwezviridzwa zvakadai seatomization pressure sensors uye tembiricha sensors, kugadzirisa nzvimbo uye kona yenozzles, etc. Kuburikidza nekugadzirisa michina, kugadzikana uye kuvimbika kwemidziyo panguva yekugadzira kunogona kuve nechokwadi, uye kufanana kwemidziyo. saizi yehupfu inogona kuvandudzwa.
3.kudzidziswa kwevashandi
Ipa kudzidziswa kwehunyanzvi kune vashandisi kuti vawedzere hunyanzvi hwavo hwekushanda uye ruzivo rwemhando. Vashandi vanofanirwa kujairana nemafambisirwo ekushandisa uye maparamita emidziyo, uye kukwanisa kuona nekukasira kugadzirisa matambudziko mukugadzira. Panguva imwecheteyo, zvinodikanwa kusimbaradza manejimendi evashandisi, kumisikidza yakasimba yekuongorora system, uye kuve nechokwadi chekumisikidza uye kujairana kwemaitiro ekugadzira.
4,Kutora tekinoroji yekuongorora
1.Laser particle size analysis
Laser particle size analyzer inowanzoshandiswa poda particle size yekuona mudziyo unogona kukurumidza uye nemazvo kuyera kugovaniswa kwehupfu. Nekuita chaiyo-nguva yekutarisa yehupfu panguva yekugadzira, zvinokwanisika kuti unzwisise panguva iyo shanduko yeupfu particle size, kuitira kugadzirisa maitiro ekugadzirisa uye kuve nechokwadi chekufanana kwehupfu particle size.
2.Electron microscopy analysis
Electron microscopy inogona kuita microscopic kuongorora kwe morphology uye chimiro chehupfu hwehupfu, zvichibatsira vatsvakurudzi kunzwisisa maitiro ekuumbwa uye kupesvedzera zvinhu zvehupfu. Kuburikidza nekuongorora kweelectron microscopy, zvikonzero zvekusaenzana kwehupfu hwehupfu hunogona kuzivikanwa, uye matanho anoenderana anogona kutorwa kuti avandudze.
Muchidimbu, kuve nechokwadi chekufanana kwehupfu chidimbu saizi musimbi yehupfu atomization michina inoda akawanda maficha, senge optimization yeatomization process paramita, kunyatso kudzora mhando yezvakagadzirwa, kusimbisa kuchengetedza kwemidziyo uye manejimendi, uye kutora tekinoroji yekuongorora. Chete nekunyatsofunga nezvezvinhu izvi uye nekuramba tichigadzira uye kuvandudza tekinoroji tinogona kugadzira simbi hupfu ine yunifomu particle size uye yakagadzikana mhando, kusangana nezvinodiwa zvemashandisirwo endima dzakasiyana.
