Binder Spray Hlau Hmoov Cov Khoom Siv Rau 3D Printing

Feem ntau, hlau 3D luam ntawv thev naus laus zis raws li kev tsim cov hmoov feem ntau xav tau cov khoom siv siab thiab lub cev thiab tshuaj lom neeg ntawm cov hmoov hlau, uas yog lub hauv paus ntawm nws txoj kev tsim kho. Siv lub tshuab luam ntawv 3D ntawm kev xaiv laser melting ua piv txwv: ntawm ib sab, nws yog ib qho nyuaj rau kev ua kom pom kev siab thiab cov ntaub ntawv uas tsis yog weldable alloy vim yog siv laser melting hlau; Ntawm qhov tod tes, cov hmoov cylinder pub tshuab muaj qhov yuav tsum tau ua ntawm cov kua dej ntawm cov hmoov hlau, uas feem ntau yog siv nrog cov tuab tuab ntawm qhov loj ntawm 15-53 μ m) Cov hlau kheej kheej ntawm cov ntawv luam tawm raws li kev tsim. cov ntaub ntawv. Cov txheej txheem kev npaj ntawm spherical hlau hmoov ntxiv nce nqi ntawm cov khoom siv raw. Binder spraying hlau 3D tshuab luam ntawv tau hloov pauv qhov xwm txheej saum toj no: hom luam ntawv cov ntaub ntawv tsis txwv, qhov loj me ntawm cov hmoov luam ntawv yog finer, thiab cov kev cai rau lub sphericity ntawm cov ntaub ntawv luam ntawv yog qis dua.

1. Ntau yam ntawm cov ntaub ntawv luam tawm

Qhia tawm tus kheej tsim tshiab AJM series nplaum txau hlau 3D tshuab luam ntawv ntawm cov cuab yeej ntse, thiab ua tiav ib feem ntawm kev sib txuas hlau hmoov nrog cov nplaum nplaum ntawm chav tsev kub. Yog li ntawd, cov ntaub ntawv raw siv tau rau kev luam ntawv ntawm cov khoom siv no yog qhov dav heev, uas tsis yog tsuas yog haum rau txhua yam hlau puag alloys, titanium puag alloys, npib tsib xee puag alloys, tab sis kuj rau refractory los yog cov hmoov hlau zoo heev xws li tungsten thiab tooj liab. Tsis tas li ntawd, los ntawm kev sim tshuaj ntsuam xyuas, cov cuab yeej siv no kuj qhia txog qhov zoo ntawm ntau yam oxide ceramics, carbide ceramics, graphite thiab lwm yam ntaub ntawv.

2. Lub cev thiab tshuaj lom neeg ntawm cov hmoov hlau

AJM series 3D tshuab luam ntawv ntawm nws tus kheej tsim los ntawm kev sib koom cov cuab yeej ntse daws qhov teeb meem ntawm cov hmoov tsis sib xws ntawm cov hmoov hlau zoo los ntawm kev siv ultrasonic hmoov pub thiab ntau cov menyuam compaction, thiab txo qis qis ntawm qhov loj me ntawm cov ntaub ntawv luam tawm los ntawm 15 μ M txuas ntxiv. mus 2m. Xyuas kom meej tias cov khoom luam tawm cov qauv ua kom zoo dua qub, qhov kev ua tau zoo thiab qhov zoo ntawm qhov chaw siab dua, thiab qhov txwv siab tshaj yog 53 μ M nthuav dav mus rau 100 μ m. Nyob rau tib lub sijhawm, cov cuab yeej siv tau qis rau kev khiav ntawm cov hmoov hlau. Txawm tias cov hmoov uas tsis yog kheej kheej nrog cov dej tsis zoo (lub kaum sab xis repose yog 25-45 degree ) tuaj yeem luam tawm thiab tsim los ntawm kev hloov cov hmoov tshuaj qis qis thiab kho cov ntawv luam tawm.

(Non spherical hmoov (AJM))

Spherical hlau hmoov feem ntau yog tau los ntawm atomization, rotating electrode los yog spheroidization, thiab tus nqi npaj yog siab. Cov hmoov hlau uas tsis yog kheej kheej tuaj yeem txuag cov kauj ruam no thiab txo tus nqi ntawm cov khoom siv raw khoom. Noj tungsten hmoov ua piv txwv, tus nqi ntawm spherical tungsten hmoov yog kwv yees li 1000 yuan / kg, thaum tus nqi ntawm cov hmoov tsis yog spherical tungsten tsuas yog 400 yuan / kg. Los ntawm kev sib piv, AJM series binder dav hlau 3D tshuab luam ntawv tuaj yeem txuag tau 3/5 ntawm tus nqi ntawm cov ntaub ntawv raw thaum luam ntawv nrog cov hmoov tsis zoo tungsten.

Hlau binder txau hlau 3D tshuab luam ntawv tau dhau los ua qhov sib txawv hauv ntiaj teb, thiab qhov zoo, kev ua tau zoo thiab tus nqi tau zoo heev. Sib koom kev lag luam binder txau hlau 3D tshuab luam ntawv rau kev tsim khoom loj ntawm nws tus kheej tsim los ntawm cov cuab yeej ntse yuav qhia tau tias muaj zog heev hauv kev tsim cov khoom siv hlau rau yav tom ntej.
