Kudiwa kweupfu hwesimbi kwakawedzera mumakore achangopfuura, zvichikonzerwa nekufambira mberi mukugadzira zvinhu zvinowedzera, zvemuchadenga, zvemotokari nedzimwe nzvimbo dzakasiyana-siyana. Upfu hwesimbi hunokosha pakuita zvinhu zvakaita sekudhinda kwe3D, sintering uye powder metallurgy. Imwe yenzira dzinoshanda kwazvo dzekugadzira upfu uhwu ndeyekushandisa metal powder atomization, maitiro anoshandura simbi yakanyungudutswa kuita zvidimbu zvidiki. Chinyorwa chino chinoongorora kuti simbi inoshandurwa sei kuita upfu, ichitarisa pabasa remidziyo ye powder atomization mukuita uku kwakakosha kwekugadzira.

Nzwisisa atomization yehupfu hwesimbi

Kugadzira hupfu hwesimbi (metal powder atomization) inzira inoshandura simbi yakanyungudutswa kuita hupfu hwakatsetseka. Tekinoroji iyi inofarirwa nekukwanisa kwayo kugadzira hupfu hune saizi, chimiro uye kugoverwa kwakafanana, izvo zvakakosha pakushandisa kwakasiyana-siyana. Maitiro ekugadzira hupfu anogona kukamurwa kuita mhando mbiri huru: kugadzira hupfu hwegasi (gas atomization) uye kugadzira hupfu hwemvura (water atomization).

Kugadziriswa kwegesi

Mukugadzira maatomu egasi, simbi yakanyungudutswa inodururwa nemumuromo wemhepo uye inoiswa maatomu nemhepo ine simba guru, kazhinji nitrogen kana argon. Kutonhora nekukurumidza kwemadonhwe akanyungudutswa kunoguma nekuumbwa kwezvidimbu zvesimbi yakasimba. Nzira iyi inonyanya kushanda pakugadzira hupfu hwakachena nekuti gasi risina kuchena rinoderedza oxidation uye kusvibiswa.

Kugadziriswa kweatomu yemvura

Kugadzira atomization yemvura, kune rumwe rutivi, kunoshandisa majeti emvura ane simba guru kupwanya simbi yakanyungudutswa kuita madonhwe. Nzira iyi inowanzo shanda uye inogona kugadzira hupfu hwakawanda. Zvisinei, inogona kukonzera oxidation, izvo zvinogona kukanganisa mashandiro echigadzirwa chekupedzisira. Kugadzira atomization yemvura kunowanzo shandiswa kugadzira hupfu hwesimbi, nepo kugadzira atomization yegesi kuchinyanya kufarirwa kune simbi dzisina ferrous uye alloys.

Maitiro ekugadzira atomization yeupfu hwesimbi

Maitiro ekushandura simbi kuita upfu kuburikidza neatomization anosanganisira matanho akakosha akati wandei:

Kunyungudutsa Simbi: Danho rekutanga nderekunyungudutsa simbi kana alloy muchoto. Izvi zvinogona kuitwa uchishandisa nzira dzakasiyana-siyana, kusanganisira induction melting, arc melting kana resistance melting. Sarudzo yenzira yekunyungudutsa inoenderana nerudzi rwesimbi uye hunhu hwaunoda hwehupfu hwekupedzisira.

Kugadziriswa kweAtomu: Kana simbi yanyungudutswa, inoendeswa kukamuri reatomization. Mukamuri iyi, simbi yakanyungudutswa inoiswa mugasi rine simba guru kana kuti jets dzemvura, zvichipwanya kuita madonhwe madiki. Saizi yemadonhwe inogona kudzorwa nekugadzirisa kumanikidzwa uye mwero wekuyerera kweatomized medium.

Kutonhodza uye Kusimba: Madonhwe acho anotonhorera uye anooma nekukurumidza paanopfuura nemukamuri rekupfapfaidza. Mwero wekutonhorera wakakosha sezvo unokanganisa chimiro che microstructure uye hunhu hweupfu hunobuda. Mwero wekutonhorera unokurumidza unowanzo gadzira zvidimbu zvakapfava uye chimiro che microstructure chakafanana.

Kuunganidza uye Kuronga: Mushure mekuoma, upfu hwesimbi hunounganidzwa uye hunorongwa zvichienderana nehukuru hwezvimedu. Izvi zvinowanzoitwa uchishandisa nzira dzekuongorora kana dzekuisa muzvikamu zvemhepo. Chigadzirwa chekupedzisira chinogona kugadziriswazve, sekukuya kana kusanganisa, kuti chiwane kugoverwa kwehukuru hwezvimedu zvinodiwa uye hunhu hwazvo.

Kugadziriswa mushure mekugadzirisa: Zvichienderana nekushandiswa, hupfu hwesimbi hungada kugadziriswa zvakanyanya, senge kuputira pamusoro kana kupisa, kuti huwedzere kunaka kwahwo. Danho iri rakakosha kuve nechokwadi chekuti hupfu hwacho hunosangana nezvinodiwa zvekushandiswa kwacho.

Basa remuchina weatomization yeupfu

Midziyo yeatomization yeupfu inzvimbo yakagadzirirwa kuita maitiro eatomization yeupfu hwesimbi zvinobudirira uye zvinobudirira. Mafekitori aya ane tekinoroji yepamusoro uye michina yekuona kuti hupfu hwemhando yepamusoro hunogadzirwa. Heano mamwe maficha akakosha emudziyo weatomization yeupfu:

1.Vira

Chinonyanya kukosha pakushandisa chero upfu hweatomization ifurnace. Yakagadzirwa kuti ishandise simbi dzakasiyana-siyana uye alloys, mafurnace aya anopa kudzora tembiricha kwakanyatsonaka kuti ave nechokwadi chekuti kunyunguduka kwakanaka. Mafurnace einduction anoshandiswa zvakanyanya nekuda kwekushanda kwawo zvakanaka uye kugona kwawo kunyungudutsa zvinhu zvakasiyana-siyana.

2.Sisitimu yeAtomu

Masisitimu eAtomization akakosha pakugadzira hupfu hwesimbi hwemhando yepamusoro. Izvi zvinosanganisira dzimba dzekupfapfaidza, ma nozzles, uye masisitimu ekupa gasi kana mvura. Sisitimu yeAtomization yepamusoro yakagadzirirwa kugadzirisa saizi yemadonhwe uye kupararira kwawo, zvichiita kuti hupfu huve hwakaenzana.

3.Sisitimu Yekutonhodza Nekuunganidza

Mushure mekushandisa atomu, masisitimu ekutonhodza nekuunganidza anoita basa rakakosha pakubata upfu hwakasimba. Masisitimu aya anowanzo sanganisira madutu, mafirita nemahopper ekuparadzanisa upfu kubva muatomizing media uye kuuunganidza kuti ugadziriswe zvakare.

4.Kudzora Hunhu uye Kuedzwa

Kudzora kunaka kwehupfu kwakakosha pakugadzirwa kwehupfu.Zvimiti zveatomization yeupfuKazhinji vane marabhoritari akatsaurirwa kuyedza hunhu hwehupfu hwavanogadzira. Izvi zvinosanganisira kuongorora saizi yezvidimbu, kuongorora chimiro uye kuongorora kuumbwa kwemakemikari kuona kuti hupfu hwacho hunosangana nezvinodiwa neindasitiri.

5.Maitiro eOtomatiki uye Kudzora Masisitimu

Mafekitori emazuva ano ekugadzira hupfu ane michina yepamusoro uye masisitimu ekudzora anogona kutarisa nekugadzirisa maitiro ese ekugadzira. Izvi zvinoita kuti pave nekuenderana, zvinoderedza kukanganisa kwevanhu, uye zvinowedzera kushanda zvakanaka.

Kushandisa upfu hwesimbi

Upfu hwesimbi hunogadzirwa neatomization hune mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana:

Kugadzira Zvimwe: Upfu hwesimbi hwakakosha pakugadzirwa kwetekinoroji yekudhinda ye3D, zvichibvumira kugadzirwa kwemajiometri akaomarara uye zvivakwa zvakareruka.

Muchadenga: Upfu hwesimbi hunoshanda zvakanyanya hunoshandiswa muzvikamu zvemuchadenga uko chiyero chesimba-kuhuremu uye kuramba mamiriro ekunze akaipisisa kwakakosha.

Mota: Upfu hwesimbi hunoshandiswa kugadzira zvikamu zveinjini, magiya nezvimwe zvikamu zvakakosha zvinoda kunyatsogadzirwa uye kugara kwenguva refu.

Zvishandiso Zvekurapa: Upfu hwesimbi hunoenderana nemakemikari hunoshandiswa kugadzira ma implants ne prosthetics kuti zvive nechokwadi chekuti zvakachengeteka uye zvinoshanda.

Zvishandiso uye Mafa: Upfu hwesimbi hunoshandiswawo mukugadzira maturusi nemadhayi, zvichipa kuomarara kunodiwa uye kuramba kupfeka.

mukupedzisa

Kushandura simbi kuita upfu kuburikidza neatomization inzira yakaoma inoita basa rakakosha mukugadzirwa kwemazuva ano. Mafekitori ekugadzira atomization eupfu ndiwo ari pamberi pehunyanzvi uhu, achipa zvivakwa zvinodiwa uye hunyanzvi hwekugadzira hupfu hwesimbi hwemhando yepamusoro hwekushandisa kwakasiyana-siyana. Sezvo indasitiri ichiramba ichichinja uye ichida zvinhu zvepamusoro-soro, kukosha kwekugadzira atomization yeupfu hwesimbi kuchakura chete, zvichigadzira nzira yekuvandudza mukugadzira nesainzi yezvinhu. Ingave iri ndege, mota kana kugadzirwa kwekuwedzera, ramangwana rehupfu hwesimbi rakajeka, richitungamirwa nekugona kwefekitori dzekugadzira atomization yeupfu.
