Nyob rau hauv tus txheej txheem ntawm ceramic lub cev sib tsoo, lubtshwj xeeb lub ntiajteb txawj nqus ntawm kev sib tsoo nruab nrabyog ib qho ntawm cov tseem ceeb tshaj plaws rau kev sib tsoo efficiency. Nws lub luag haujlwm feem ntau cuam tshuam los ntawm qhov ntev xws li kev hloov pauv hluav taws xob kinetic, cov khoom sib cuag zaus, thiab kev sib tsoo ib puag ncig adaptability, ncaj qha txiav txim siab tus nqi sib tsoo, cov khoom tiav qhov loj me, thiab kev siv zog.
I. Kev sib raug zoo ntawm kev sib tsoo nruab nrab qhov tshwj xeeb lub ntiajteb txawj nqus thiab sib tsoo Kinetic zog
Cov nyhuv sib tsoo ntawm qhov sib tsoo nruab nrab tseem ceeb yog nyob ntawm qhovcuam tshuam lub zogthiabshear zoggenerated thaum nws txav mus rau hauv lub zeb kom ua tiav cov crushing thiab refinement ntawm ceramic hais. Lub ntiajteb txawj nqus tshwj xeeb yog cov ntsiab lus tseem ceeb uas txiav txim siab qhov nruab nrab lub zog kinetic (kinetic zog mis \\(E=\\frac{1}{2}mv^2\\), qhov loj m yog qhov zoo sib xws nrog lub ntiajteb txawj nqus tshwj xeeb):
Siab- tshwj xeeb- cov xov xwm nqus: Nyob rau hauv tib lub zog ceev thiab ntim ntim, ib qho nruab nrab ib qho me me muaj qhov loj dua thiab muaj zog cuam tshuam rau lub zog kinetic, uas tuaj yeem ua kom muaj txiaj ntsig zoo dua ntawm cov ciam teb thiab cov agglomerates ntawm ceramic hais. Lawv yog tshwj xeeb tshaj yog haum rau covceev crushing ntawm ntxhib ceramic raw cov ntaub ntawv(xws li thawj zaug sib tsoo ntawm cov ceramics nyuaj xws li alumina thiab zirconia). Piv txwv li, zirconia hlaws dai (nrog rau lub ntiajteb txawj nqus ntawm kwv yees li 6.0-6.2) muaj kev cuam tshuam ntau dua kinetic zog dua li cov iav hlaws (nrog rau lub ntiajteb txawj nqus ntawm kwv yees li 2.5), thiab tuaj yeem txhim kho cov crushing efficiency ntawm high-hardness ceramics los ntawm 30% -50%.
Tsawg- tshwj xeeb- cov xov xwm nqus: Lawv muaj lub zog kinetic tsis muaj zog thiab muaj kev cuam tshuam me me, ua rau nws nyuaj rau kev ua tiav sai ntawm cov khoom siv ceramic loj. Txawm li cas los xij, lawv tuaj yeem txo qhov cuam tshuam ntau dhau ntawm cov khoom ua kom zoo dua qub thiab zam cov khoom siv lattice distortion, ua rau lawv haum rauzoo sib tsoo los yog polishing theem ntawm ceramic hmoov.
II. Kev cuam tshuam rau cov khoom sib cuag thiab cuam tshuam
Hu rau zaus: Lub ntiajteb txawj nqus tshwj xeeb cuam tshuam rau lub xeev txav ntawm qhov nruab nrab hauv lub zeb. High- tshwj xeeb- lub ntiajteb txawj nqus tawm sai dua nyob rau hauv qhov kev txiav txim ntawm lub zog centrifugal lossis lub ntiajteb txawj nqus, ua rau muaj kev sib tsoo ntau dua thiab kev sib txhuam ntau dua nrog cov khoom siv ceramic, uas tuaj yeem txo cov khoom sib tsoo. Tsawg- tshwj xeeb- cov xov xwm lub ntiajteb txawj nqus yuav raug ncua hauv slurry thiab ua kom muaj kev sib cuag nrog cov ntaub ntawv ntau dua, haum rau kev tawg thiab sib tsoo ntawm siab -viscosity ceramic slurries, thiab tuaj yeem zam hauv zos dhau- sib tsoo.
Anti-cov nyhuv agglomeration: Rau cov hmoov ceramics uas nquag mus rau agglomeration (xws li nano{0}} nplai ceramic hmoov), lub zog shear quab yuam ntawm siab - tshwj xeeb - lub ntiajteb txawj nqus xov xwm tuaj yeem ua rau lub zog van der Waals thiab hydrogen bonds nruab nrab ntawm cov khoom, thaum cov nyhuv me me ntawm qis -cov ntaub ntawv tshwj xeeb ntawm cov xov xwm sib txawv ntawm - muaj peev xwm ua kom muaj kev ruaj ntseg. agglomeration.
III. Adaptability rau Ceramic lub cev yam ntxwv
Hard ceramics(xws li silicon carbide thiab silicon nitride): Yuav tsum muaj siab - tshwj xeeb - nqus thiab siab - hardness sib tsoo xov xwm (xws li zirconia hlaws thiab steel hlaws). Lawv lub zog kinetic siab yog siv los kov yeej lub siab tawg lub zog ntawm ceramics thiab txhim kho kev sib tsoo. Yog tias qis- tshwj xeeb- cov xov xwm nqus tau siv, tsis yog tsuas yog qhov ua tau zoo yuav tsawg, tab sis impurities kuj yuav raug tsim tawm vim hnav nruab nrab, paug cov hmoov ceramic.
Mos los yog tsawg- hardness ceramics(xws li ceramic glazes thiab porous ceramic raw cov ntaub ntawv): Nws tsim nyog rau qis- tshwj xeeb- cov xov xwm sib nqus (xws li alumina hlaws thiab iav hlaws), uas tuaj yeem tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm kev sib tsoo fineness tab sis kuj txo qis hnav ntawm cov xov xwm lawv tus kheej thiab tswj cov nqi tsim khoom.
IV. Kev cuam tshuam rau kev siv hluav taws xob thiab khoom siv
Kev siv hluav taws xob sib npaug: Txawm hais tias siab - tshwj xeeb- lub ntiajteb txawj nqus xov xwm muaj kev sib tsoo siab, lawv yuav ua rau kev tsav tsheb ntawm lub zeb, ua rau muaj kev siv zog ntxiv rau ib lub sijhawm. Tsawg- tshwj xeeb- lub ntiajteb txawj nqus xov xwm muaj qis zog noj tab sis lub voj voog sib tsoo ntev dua, yog li nws yuav tsum sib npaug ntawm "kev ua tau zoo- siv zog" kev sib raug zoo.
Khoom siv: Ntau dhau heev lawm - tshwj xeeb- lub ntiajteb txawj nqus xov xwm (xws li cov hlaws dai steel) yuav ua rau lub zog ntawm lub zeb liner, thaum cov xov xwm nrog lub ntiajteb txawj nqus tshwj xeeb txuam nrog cov ntaub ntawv ceramic (xws li alumina hlaws rau alumina ceramic sib tsoo) tuaj yeem txo cov khoom siv poob thiab hmoov av.
