Ib, Ceramic Beads Abrasives yog ib qho tseem ceeb hauv kev lag luam kev sib tsoo, vim lawv cov khoom siv tshwj xeeb thiab cov qauv zoo, nthuav tawm cov txiaj ntsig tseem ceeb hauv ntau hom kev sib tsoo,
Lub ntsiab kom zoo dua ntawm cov pob zeb ceramic hauv av yog nyob rau hauv qhov zoo heev abrasion tsis kam ua los ntawm cov yam ntxwv siab hardness ntawm lawv cov ntaub ntawv tseem ceeb xws li alumina, zirconia, silicon carbide, thiab lwm yam.:
1. Alumina ceramic hlaws dai (Al2 o3 cov ntsiab lus ntau dua 90%) Mohs hardness mus txog 8 - 8.5, ntau dua li cov hlaws hlau zoo tib yam (xws li cov hlaws hlau, Mohs hardness 4 - 5) thiab iav hlaws (Mohs hardness 5.5 - 6), hnav tus nqi nyob rau hauv ntev - lub sij hawm sib tsoo yog tsawg heev;
2. zirconia ceramic hlaws dai (zro₂ cov ntsiab lus ntawm ntau dua 95%) tsis tsuas yog siab hardness (Mohs hardness 8.5), tab sis kuj muaj qee qhov toughness, uas tuaj yeem txo qhov tawg vim muaj kev cuam tshuam thiab txuas lub neej kev pab cuam;
3. silicon carbide ceramic hlaws (Mohs hardness 9.5) yog ze rau pob zeb diamond hardness thiab haum rau kev sib tsoo cov ntaub ntawv siab hardness (xws li ore, silicon carbide hmoov), qhov ua kom tsis haum yog ntau tshaj 10 npaug ntawm cov hlaws steel.
2, Nta ntawm ceramic hlaws:
1.Strong tshuaj stability, tsis muaj paug los ntawm impurities
2.Qhov kev sib tsoo efficiency siab thiab cov nyhuv refining zoo
3. high density, siab hardness ntawm Abrasive ceramic hlaws, yog li ntawd lawv tuaj yeem tawg cov khoom sai sai los ntawm kev cuam tshuam ntau zaus thiab txiav txiav, txhim kho kev sib tsoo efficiency:
3, Qhov zoo ntawm ceramic hlaws:
1. qhov ceev ntawm zirconia ceramic hlaws yog li ntawm 6.0 G / cm³, ntau dua iav hlaws (2.5 G / cm³) thiab cov hlaws yas (1.2 - 1.5 g / cm³), ntawm tib qhov kev sib hloov ceev, nws lub peev xwm gravitational loj dua, qhov cuam tshuam rau ntawm cov khoom muaj zog, tuaj yeem tawg cov agglomeration sai;
2.high circularity ntawm ceramic hlaws dai (circularity ntawm cov khoom feem ntau> 95%) ua kom lub zog du hauv cov khoom siv crushing (xws li xuab zeb crusher, pob crusher), txo cov kev sib txhuam tsis zoo nrog cov khoom siv hauv phab ntsa, hloov ntau lub zog rau hauv kev sib tsoo ntawm cov khoom siv;
3.s me me ceramic hlaws dai (xws li zirconia microbeads los ntawm 0.1 mus rau 1mm) tuaj yeem muab qhov tshwj xeeb loj dua, ua kom tiav kev sib cuag nrog cov khoom siv, haum rau kev sib tsoo zoo (xws li, nanoscale av nkos npaj), tuaj yeem ua kom zoo - kho qhov me me ntawm cov khoom hauv qab 1μm.

6, Ceramic Beads Abrasives tuaj yeem hloov kho rau ntau qhov kev xav tau sib tsoo thiab cov khoom siv nyob ntawm seb hom khoom, qhov loj me, qhov ceev:
1. los ntawm kev sib tsoo ntxhib (xws li ore sib tsoo, xaiv alumina hlaws los ntawm 5 mus rau 20mm) kom tiav kev sib tsoo (xws li kev hloov xim number case, xaiv zirconia hlaws los ntawm 0.5 mus rau 2mm), npog qhov sib txawv particle loj yuav tsum tau;
2. yoog mus rau ntau yam khoom siv xws li kab rov tav xuab zeb zeb, ntsug pob zeb, nplawm zeb, airflow zeb, thiab lwm yam, thiab yog sib xws nrog cov khoom siv morphology (kua, muab tshuaj txhuam, hmoov);
3. kub resistant (piv txwv li, silicon nitride npas tuaj yeem ua haujlwm ntawm 1200 degree), tsis tshua muaj kub resistant, haum rau kev ua hauj lwm huab cua (piv txwv li, kub kub ceramic billet sib tsoo, kub tsis tshua muaj tshuaj cov ntaub ntawv sib tsoo).
