Xaiv cov hmoov metallurgy binders,hlau hmoov txhaj molding tshuabyog cov khoom ntawm kev sib koom ua ke thiab kev sib tshuam ntawm cov yas molding tshuab, polymer chemistry, hmoov metallurgy technology thiab hlau cov ntaub ntawv science. Cov pwm tuaj yeem siv los txhaj tshuaj pwm qhov khoob thiab dhau los ntawm Sintering tuaj yeem ua kom nrawm nrawm, siab-precision, peb-dimensional complex-shaped structural qhov chaw. Nws tuaj yeem ua tau sai thiab raug tsim cov tswv yim tsim rau hauv cov khoom nrog qee yam qauv thiab kev ua haujlwm zoo, thiab tuaj yeem ncaj qha rau cov khoom tsim tawm. Nws yog ib qho kev hloov tshiab hauv kev tsim khoom siv thev naus laus zis.
Txheej txheem nta:
Cov txheej txheem thev naus laus zis no tsis yog tsuas yog muaj qhov zoo ntawm cov txheej txheem hmoov hlau metallurgy xws li cov kauj ruam tsawg dua, tsis muaj los yog txiav tsawg dua, thiab cov txiaj ntsig kev lag luam siab, tab sis kuj overcomes cov shortcomings ntawm tsoos.hmoov metallurgy khoomxws li cov ntaub ntawv tsis sib xws, cov khoom siv tsis zoo, thiab nyuaj rau kev tsim cov phab ntsa nyias thiab cov txheej txheem nyuaj. Nws yog tshwj xeeb tshaj yog haum rau loj zus tau tej cov me me, complex thiab tshwj xeeb hlau qhov chaw. Cov txheej txheem ntws: binder → sib tov → txhaj tshuaj molding → degreasing → sintering → post-processing.
hmoov hlau hmoov:
Qhov loj me me ntawm cov hmoov hlau siv hauvMIM processfeem ntau yog 0.5 ~ 20μm; theoretically, qhov finer hais, qhov loj ntawm qhov chaw nto, ua kom yooj yim rau cov duab thiab sinter. Cov txheej txheem hmoov metallurgy siv cov hmoov coarser loj dua 40μm.
Hauv kev txhaj tshuaj molding MIM, lub binder plays lub luag haujlwm tseem ceeb heev, nws cuam tshuam ncaj qha rau kev sib xyaw, kev txhaj tshuaj molding, degreasing thiab lwm yam txheej txheem, thiab muaj kev cuam tshuam zoo rau qhov zoo, degreasing thiab qhov tseeb ntawm cov hlau hmoov txhaj tshuaj molding dawb paug, alloy muaj pes tsawg leeg, thiab lwm yam. yog, nws dhau los ua tus neeg nqa khoom los tsav cov dej ntws ntawm cov hmoov. Yog li ntawd, kev xaiv ntawm binder yog tus yuam sij rau kev tsim ntawm tag nrho cov hmoov txhaj tshuaj. Cov kev xav tau rau binder:
- me me, uas yog, los xyuas kom meej tias cov sib tov muaj rheology zoo dua thaum siv me me binder li sai tau;
- Tsis muaj tshuaj tiv thaiv, piv txwv li tsis muaj tshuaj tiv thaiv nrog hlau hmoov;
- Yooj yim tshem tawm, tsis muaj residue hauv cov khoom.
Tus ntsuj plig ntawm binder hmoov metallurgy MIM txheej txheem, nws ntxiv thiab tshem tawm yog lub tshuab tseem ceeb ntawm MIM, thiab cov txheej txheem degreasing siv nyob rau hauv cov txheej txheem binder yog lub ntsiab lus tseem ceeb ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws. Cov binders siv nyob rau hauv MIM muaj xws li thermoplastic systems, thermoset systems, dej-soluble systems, gel systems thiab tshwj xeeb systems, txhua yam uas muaj nws tus kheej zoo thiab tsis zoo. Thermoplastic binder system yog lub ntsiab lus tseem ceeb thiab ua ntej ntawm MIM binder, thiab tib neeg tsom mus rau kev txhim kho rheological zog ntawm cov khoom noj pub mis, ntau txoj kev tshawb fawb tau ua los txo qis degreasing deformation thiab txo lub sij hawm degreasing, thiab qee cov neeg ua haujlwm tshwj xeeb suav nrog polyacetal binders tau tsim.Cov txheej txheem tshwj xeeb tau ua rau kev txhim kho ntxiv ntawm cov khoom siv thermoplastic. Tab sis kev tshawb fawb thiab kev loj hlob ntawm binders tsis muaj hmoov
Affinity, sib tov ntawm hmoov thiab binders, rheological thiab thermodynamic zog ntawm binders thiab pub nyob rau hauv ntau yam kev mob, lub cawv ntawm binders ntawm degreasing thiab cov khoom khoom muab universal lub hauv paus ntsiab lus thiab theoretical hauv paus rau kev xaiv ntawm binders, uas yog undoubtedly cim Nws muaj lub ntsiab lus zoo heev. Txoj kev loj hlob ntawm ib tug tshiab thiab zoo binder system kuj yog lub hom phiaj ntawmMIM technology.
