Cov hmoov hlau zoo li cas rau 3D luam ntawv? Yuav ua li cas npaj xws li hmoov hlau
Cov khoom siv dav siv hauv kev luam ntawv rau 3D luam ntawv feem ntau suav nrog plaub hom hauv daim ntawv: kua photosensitive resin khoom, cov khoom nyias, cov khoom siv hlau tsis tshua muaj melting point, thiab cov khoom siv hmoov; Nyob rau hauv cov nqe lus ntawm muaj pes tsawg leeg, nws npog yuav luag txhua yam ntawm cov ntaub ntawv nyob rau hauv tam sim no ntau lawm thiab lub neej, xws li yas, resin, wax, thiab lwm yam ntaub ntawv polymer, hlau thiab alloy cov ntaub ntawv, cov ntaub ntawv ceramic, thiab lwm yam. Ntawm lawv, hlau hmoov 3D luam ntawv yog undoubtedly ntawm lub forefront thiab muaj peev xwm loj hlob.
Tam sim no, 3D luam ntawv hlau hmoov cov ntaub ntawv suav nrog stainless hlau, tuag hlau, npib tsib xee alloy, titanium alloy, cobalt-chromium alloy, aluminium alloy, thiab tooj liab alloy.
Yog li, koj yuav npaj cov hmoov hlau zoo li cas rau 3D luam ntawv?
1. Argon atomization txoj kev
Txoj kev argon atomization yog ib txoj kev pulverizing uas siv cov roj argon ceev ceev los cuam tshuam cov kua hlau, crushing rau hauv cov khoom zoo thiab tom qab ntawd condensing nws mus rau hauv cov hmoov khoom.
2. Plasma atomization
Cov txheej txheem pulverizing ntawm plasma atomization txoj kev tuaj yeem piav qhia raws li cov khoom siv raw, xws li cov pas nrig thiab cov xov hlau, raug xa ncaj qha mus rau qhov chaw kub kub ntawm cov ntshav tsom los ntawm ib qho khoom noj tshwj xeeb. Cov ntaub ntawv raw yog yaj sai sai los yog vaporized, los yog decomposed los ntawm thermal cov tshuaj tiv thaiv rau synthesize, atomize Hlau, los yog ceramic hmoov cov ntaub ntawv ntawm ntau yam ntaub ntawv ntawm ultra-fine / nano theem yog npaj. Tom qab ntawd cov tee dej tau txias sai thiab khov rau hauv cov hmoov kheej kheej nyob rau hauv qhov kev txiav txim ntawm qhov nro. Cov ntaub ntawv hmoov npaj tau txias, muab tso rau hauv lub tshuab atomization ntauwd, thiab khaws cia hauv nruab nrab. Cov pa roj atomized yog lim thiab lim, thiab tom qab ntawd tawm mus.
3. Radiofrequency plasma spheroidization
Cov khoom siv tsis tu ncua zoo li cov hmoov nplej yog txau rau hauv lub plasma teeb los ntawm cov hmoov feeder nrog cov pa roj (argon). Cov hmoov hmoov nqus cov cua kub ntau hauv cov ntshav plasma kub, thiab cov nplaim yaj sai sai, nkag mus rau lub reactor ntawm qhov kub ceev. Kev ua kom txias sai sai hauv qhov chaw tsis muaj zog, nyob rau hauv qhov kev txiav txim ntawm qhov nro, txias thiab ua kom khov rau hauv cov hmoov kheej kheej, thiab tom qab ntawd nkag mus rau hauv qhov chaw txais khoom rau kev sau.
Cov hmoov hlau ua tau raws li qhov no muaj qhov zoo hauv qab no:
High sphericity, du nto, zoo fluidity, thiab siab bulk ntom, yog li cov hmoov sib kis uniformity yog zoo, thiab cov khoom luam tawm muaj siab ceev;
Cov hmoov me me me me, nqaim particle loj faib, cov ntsiab lus tsis tshua muaj oxygen, me me / tsis muaj spheroidization thiab agglomeration thaum luam ntawv, cov nyhuv melting zoo, cov khoom lag luam siab tiav, thiab qhov sib xws thiab kev luam ntawv tuaj yeem lav tag nrho;
Tsis muaj hollow hmoov thiab satellite hmoov, thiab yuav tsis muaj qhov tsis xws luag xws li huab cua qhov khoob, qhov nkag thiab nag lossis daus pores, thiab cov kab nrib pleb tshwm sim los ntawm hollow spheres thaum lub sij hawm luam ntawv.
