Hlau Txhaj Moulding (MIM), tseem hu ua hmoov txhaj tshuaj molding (PIM), yog cov txheej txheem tsim khoom siab tshaj plaws uas sib txuas cov qauv ntawm cov yas txhaj tshuaj molding thiab hmoov metallurgy los tsim cov khoom siab tshaj -cov khoom hlau. Keeb kwm tsim rau ceramic molding, txoj kev no tau hloov kho rau cov hlau hauv xyoo 1970 los ntawm Raymond Wiech thiab tau dhau los ua lub hauv paus ntawm kev tsim cov hlau niaj hnub, tshwj xeeb tshaj yog rau kev nyuaj, siab - ntim qhov chaw.
Txheej txheem txheej txheem
Hauv MIM, cov hmoov hlau zoo yog homogenized nrog cov thermoplastic binder los tsim cov khoom noj khoom haus moldable. Qhov sib tov yog txhaj rau hauv pwm siv cov cuab yeej molding txheem, txias, thiab demolded rau hauv "ntsuab qhov chaw." Tom qab debinding thiab sintering theem tshem tawm cov binder thiab densify cov hlau qauv, xyuas kom meej qhov ntev, cov khoom purity, thiab txhua yam kev ncaj ncees.
Lub luag haujlwm tseem ceeb ntawm Advanced Materials hauv Sintering
Lub sintering rauv lub thermal teb, ib qho tseem ceeb ntawm MIM, cia siab rauCarbon Fiber Rigid Felt rau nws qhov tshwj xeeb thermal stability thiab niaj hnub cua sov faib ntawm huab cua kub. This material ensures consistent sintering conditions, enabling precise control over densification and shrinkage (typically 75–85% of the molded size). Rau cov khoom siv nyob rau hauv qhov cub, xws li cov khoom siv phaj,Carbon /CarbonCtsis sib haumMaterialfeem ntau xaiv vim nws qhov kev sib txuam tsis sib xws ntawm siab -kub tsis kam, txhua yam muaj zog, thiab kev tiv thaiv corrosion. Cov pa roj carbon qib siab no-raws li cov ntaub ntawv sib sau ua ke txhim kho cov txheej txheem kev ntseeg siab thiab kev ua haujlwm ntawm cov khoom lag luam, tshwj xeeb tshaj yog nyob rau hauv aerospace thiab kev kho mob daim ntawv thov qhov twg thermal tswj thiab cov khoom siv ntev yog qhov tseem ceeb.
Qhov zoo ntawm MIM
MIM ua tau zoo tshaj plaws hauv pawg- ua kom zoo nkauj, nyob ze -net- cov khoom zoo sib xws nrog kev ua siab ntev, tshem tawm cov tshuab ua haujlwm thib ob. Ua tau zoo nrog ntau hom ferrous thiab tsis yog -ferrous alloys, nws muab cov nqi ua haujlwm zoo dua li cov txheej txheem xws li casting lossis forging. Nws daim ntawv thov nthuav dav kev lag luam uas xav tau qhov tseeb- tsheb, hluav taws xob, khoom siv kho mob (xws li, cov cuab yeej phais, kev cog hniav), thiab kev tiv thaiv kab mob.
Cov txiaj ntsig Sintering
- Uniform densification: Tshem tawm cov porosity thaum tswj kev xav tau shrinkage rau qhov sib xws.
- Khoom siv purity: Ua kom tiav binder tshem tawm kom ntseeg tau tias biocompatibility thiab corrosion kuj.
- Ua kom muaj zog: Ua tiav lub zog siab, hardness, thiab hnav tsis kam, zoo tagnrho rau cov iav, cov khoom siv, thiab siab - cov khoom siv zog.
Kev tsim kho tshiab hauv qhov cub tsim
Kev koom ua ke ntawm Carbon Fiber Rigid Felt nyob rau hauv sintering rauv thermal systems thiabCarbon /CarbonCtsis sib haumMaterialrau kev thauj khoom-cov kabmob cov kabmob underscores MIM qhov kev hloov pauv raws li kev ua haujlwm siab -tech. Cov ntaub ntawv no ua rau muaj kev ua haujlwm ruaj khov ntawm qhov kub txog li 99% ntawm cov hlau melting point (xws li ~ 1300-1500℃rau stainless hlau), optimizing diffusion bonding thiab qhov kawg ntawm kev ua tau zoo nyob rau hauv huab ib puag ncig.
