Dub silicon carbideyog ib qho tseem ceeb abrasive khoom siv dav hauv kev sib tsoo, txiav, cov khoom siv refractory, thiab lwm yam kev siv hauv kev lag luam. Nws hardness thiab hnav tsis kam muaj kev cuam tshuam ncaj qha rau kev sib tsoo efficiency, abrasive noj, thiab cov cuab yeej siv lub neej.
Dub Silicon Carbide Ua li cas?
Kev lag luam dub silicon carbide yog tsim los ntawm smelting quartz xuab zeb thiab roj av coke nyob rau hauv ib qho hluav taws xob tsis kam rauv ntawm qhov kub thiab txias. Tom qab ntawd cov blocks uas tau tshwm sim yog crushed, kua qaub- thiab alkali- ntxuav, sib nqus hlau nplaum, thiab tshuaj ntsuam los yog dej- cais los ua qhov sib txawv grit.
Nyob ntawm daim ntawv thov, cov khoom siv tuaj yeem ua tiav rau hauv cov nplej ntxhib rau cov cuab yeej abrasive lossis hmoov zoo rau kev sib tsoo thiab qhov chaw tiav.
Dab tsi yog qhov Hardness ntawm Black Silicon Carbide?
Dub silicon carbide feem ntau muaj Mohs hardness txog 9.2-9.5, ua rau nws yog ib qho nyuaj rau cov khoom siv abrasive. Nws hardness yog nruab nrab ntawm alumina thiab pob zeb diamond, thaum nws lub zog txhua yam yog siab dua li ntawm alumina hauv ntau daim ntawv thov abrasive.
Nws cov npoo txiav ntse thiab hnav zoo ua rau nws haum rau kev sib tsoo thiab txiav cov ntaub ntawv nyuaj lossis nkig. Rau kev sib tsoo lub log thiab lwm yam cuab yeej abrasive, txawm li cas los xij, hardness tsis yog tib yam cuam tshuam rau kev ua haujlwm. Cov qoob loo loj, cov qoob loo zoo, friability, thiab hnav tsis kam kuj cuam tshuam rau kev txiav thiab kev siv abrasive.
Yuav Ua Li Cas Dub Silicon Carbide Hardness Test?
Muaj ntau txoj hauv kev tuaj yeem siv los ntsuas nws qhov muaj pes tsawg leeg thiab cov yam ntxwv particle.
1. Atomic Absorption Spectrometry
Atomic absorption spectrometry tuaj yeem txiav txim siab cov ntsiab lus ntawm cov khoom xws li silicon. Cov txiaj ntsig tau pab ntsuas cov khoom muaj pes tsawg leeg thiab purity, muab cov ntaub ntawv muaj txiaj ntsig zoo rau kev tswj xyuas tag nrho.
2. Kev ntsuas hluav taws xob tiv thaiv kab mob
Ib qho hluav taws xob tiv thaiv particle analyzer tuaj yeem ntsuas particle-size tis. Txij li cov grit loj muaj qhov cuam tshuam ncaj qha rau kev sib tsoo thiab txiav tus cwj pwm, txoj kev no yog qhov tseem ceeb rau kev soj ntsuam kev ua haujlwm thiab tswj xyuas cov lus qhia zoo ib yam.
3. Particle Shape Analysis
Lub particle analyzer tuaj yeem ntsuas qhov zoo ntawm cov qoob loo thiab cov tsis muaj feem cuam tshuam. Grain morphology cuam tshuam rau kev ua haujlwm ntawm kev sib tsoo, kev sib tsoo, thiab ua kom tiav, ua cov particle-cov duab tsom xam muaj txiaj ntsig zoo rau kev ntsuas qhov zoo thiab sib xws ntawm cov nplej abrasive.
Qhov twg yog Dub Silicon Carbide siv?
Niaj hnub no, dub silicon carbide yog siv nyob rau hauv sib tsoo log, txiav cov cuab yeej, coated abrasives, abrasive blasting, txiav kua, refractory khoom, steelmaking additives, industrial flooring, thiab ceramic sintering.
Nws ua ke ntawm kev nyuaj siab, hnav tsis kam, thermal conductivity, thiab siab - kub stability tso cai rau nws ua tau zoo nyob rau hauv xav tau kev lag luam ib puag ncig. Thaum xaiv cov xim dub silicon carbide rau cov ntawv siv abrasive, yam xws li grit loj, purity, grain zoo, thiab hnav cov yam ntxwv yuav tsum tau txiav txim siab nrog rau hardness kom ua tau zoo sib tsoo kev ua tau zoo thiab cov khoom siv tau zoo.
