Daim ntawv thov kev txawj ntawm Zirconia Pob Milling hlaws
Muaj qee qhov kev txawj ntse hauv kev siv cov pob zirconia. Piv txwv li, xaiv txoj cai zirconia hlaws yuav cuam tshuam kev sib tsoo sib txawv, nce lossis txo hnav. Yog li ntawd, nws yog ib qho tsim nyog los xaiv cov zirconia microbeads haum.
Kev cuam tshuam ntawm kev xaiv ntawm zirconia hlaws ntawm kev sib tsoo
Mohs hardness thiab Vickers hardness feem ntau siv cov ntsuas. Feem ntau, qhov nyuaj ntawm zirconia hlaws dai, qhov hnav tus nqi ntawm cov hlaws qis dua. Los ntawm kev hnav cov zirconia hlaws ntawm qhov chaw sib cuag ntawm cov xuab zeb (dispersing phaj, pas nrig pin, puab lub tog raj kheej, thiab lwm yam), zirconia hlaws nrog siab hardness nyob rau hauv kev sib cuag qhov chaw hnav ntau dua, tab sis zirconia hlaws dai nrog du nto ntawm lub tog raj kheej. thiab cov phaj dispersing hnav kuj me dua. Nyob rau tib lub sij hawm, tsis xws li cov filling npaum li cas ntawm abrasive hais, cov khoom viscosity thiab txaus tus nqi yuav raug kho kom ua tau ib tug zoo optimization point.
(2) Particle loj
Qhov loj ntawm zirconia hlaws txiav txiav cov naj npawb ntawm cov ntsiab lus ntawm cov hlaws thiab cov khoom. Nyob rau hauv tib lub ntim, ntau cov ntsiab lus ntawm cov hlaws dai nrog me me me me, kev sib tsoo zoo dua thaum lub sij hawm sib tsoo, thiab kev sib tsoo ntau dua. Nyob rau hauv tib lub sij hawm sib tsoo, thaum siv me me txoj kab uas hla sib tsoo hlaws, cov khoom fineness yog zoo dua thaum siv loj txoj kab uas hla sib tsoo tawm. Ntawm qhov tod tes, thaum sib tsoo cov ntaub ntawv nrog cov khoom loj loj, piv txwv li, rau 100 micron cov ntaub ntawv, nws tsis tas yuav siv cov hlaws dai nrog d=1 hli, vim tias lub zog ntawm cov hlaws me me tsis tuaj yeem ncav cuag lub zog ntawm kev ua tiav. sib tsoo dispersion. Hauv qhov no, cov hlaws dai nrog qhov loj me me yuav tsum tau siv.
(3) Ceev
Cov ntaub ntawv dav dav, qhov ceev tau qhia txog ntom ntom (qhov tseeb ntom ntom) thiab ceev ntom ntom). Qhov hnyav molecular thiab feem pua ntawm cov oxides ntau yam txiav txim siab qhov ntom ntawm zirconia hlaws. Feem ntau, ntau dua qhov ceev ntawm zirconia hlaws, qhov ntau dua lub zog kinetic generated los ntawm kev sib hloov ntawm lub zeb, thiab ntau dua qhov sib tsoo efficiency. Ntawm qhov tod tes, qhov siab dua qhov sib tsoo nruab nrab, qhov ntau dua qhov hnav ntawm qhov chaw sib cuag ntawm cov xuab zeb zeb (lub tog raj kheej sab hauv, cov phaj dispersing, thiab lwm yam), yog li qhov sib txuam ntawm cov khoom viscosity thiab ntws los ua tus yuam sij. Tsawg ntom zirconia hlaws yog tsim rau cov ntaub ntawv uas tsis muaj viscosity, thaum lub siab ceev zirconia hlaws yog tsim rau cov ntaub ntawv viscosity siab.
Tsim nyog tus nqi sau
Lub filling tus nqi ntawm zirconia microbeads yog tus naj npawb ntawm kev sib tsoo microbeads xav tau los ntawm cov xuab zeb zeb kom zoo dua dispersion thiab sib tsoo nyhuv. Yog tias qhov ntim ntawm cov hlaws sib tsoo siab dhau lawm, nws yooj yim ua rau qhov kub thiab txias ntawm lub tshuab sib tsoo kom nce, thiab lub tog raj kheej tsis tuaj yeem txias rau lub sijhawm thiab nres. Lub filling tus nqi ntawm kev sib tsoo hlaws yog tsawg heev, kev sib tsoo efficiency yog tsawg, thiab qhov nruab nrab poob yog loj. Yog li ntawd, tus nqi tsim nyog filling yog ib qho tseem ceeb ntawm kev txhim kho kev sib tsoo.
Nyob rau hauv cov xuab zeb zeb kev khiav hauj lwm phau ntawv, ntim ntsuas feem ntau yog siv los qhia tus nqi sau, tab sis qhov no yuav tsum tau hloov mus rau qhov tseeb sau loj ntawm cov xov xwm hauv ntau lawm. Kev suav cov mis=zoo ntim ntawm xuab zeb zeb × filling tus nqi × sib tsoo nruab nrab bulk ntom
2. Ntxiv kev sib tsoo xov xwm
1. Lub hauv paus ntsiab lus ntawm kev ntxiv kev sib tsoo xov xwm
Yog tias koj pom qhov txo qis hauv kev sib tsoo ntawm cov grinder, nws yuav yog lub teeb liab rau qhov sib ntxiv ntawm cov hlaws dai. Cov neeg siv tuaj yeem tshuaj xyuas tsis tu ncua thiab ntxiv cov hlaws dai raws li lawv tus kheej cov txheej txheem thiab qhov tseeb hlaws poob tus nqi.
2. Yuav ua li cas ntxiv cov xov xwm sib tsoo
Qhov luaj li cas ntawm cov hlaws dai yuav ua me me thiab me me vim lub ntuj attrition ntawm cov hlaws dai. Txhawm rau kom tswj tau cov nyiaj tsis sib xws thiab zam cov hlaws zoo los ntawm kev txhaws lossis nkag mus rau hauv cov khoom sib cais, cov hlaws yuav tsum tau tshuaj xyuas thiab ntxiv nrog qee qhov kev sib tsoo xov xwm raws li kev pabcuam lub neej ntawm kev sib tsoo xov xwm thiab tus neeg siv tus kheej cov txheej txheem.
