Silicon carbide hmoov yog ib yam ntawm cov khoom siv superhard, uas yog dav siv los ua cov cuab yeej abrasive, resin polishing sib tsoo log thiab pob zeb diamond polishing sib tsoo log, thiab lwm yam. Silicon carbide nws tus kheej muaj siab hardness, ua rau nws cov particle loj faib mus txog qhov txwv ntau, nws yog qhov nyuaj heev rau kev sib tsoo thiab muab qhab nia ntawm silicon carbide hmoov, thiab nrog rau kev tsim cov khoom lag luam, kev tshawb fawb thiab thev naus laus zis thiab kev xav tau ntawm kev lag luam, Cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev tsim cov hmoov SIC, nrog rau kev tsim khoom siab, kev siv hluav taws xob tsawg. , nqaim particle loj tis thiab muaj kuab paug tsawg. Lub dav hlau zeb yog tsim rau ultrafine sib tsoo ntawm superhard cov ntaub ntawv xws li silicon carbide, pob zeb diamond thiab cubic boron nitride.
Lub hauv paus ntsiab lus ntawm lub tshuab cua tshuab yog tias nyob rau hauv qhov kev txiav txim ntawm high-ceev cua khiav, cov hais yog crushed los ntawm kev cuam tshuam kev sib tsoo, kev sib txhuam thiab shear ntawm cov hais los yog cov khoom thiab lub hom phiaj. Air flow sib tsoo muaj cov yam ntxwv hauv qab no:
(1) Cov huab cua ceev ceev yuav ua rau muaj kev kub ceev ntawm cov khoom, qhov cuam tshuam lub zog ntawm cov khoom yog loj, thiab cov hmoov ultrafine ntawm micron lossis txawm tias sub-micron tuaj yeem tau txais;
② Cov khoom particle muaj siab purity thiab me me;
③ Cov khoom tau txais tau nqaim particle loj faib, du particle morphology thiab zoo particle dispersion;
④ Qhov kub ntawm cov huab cua ntws los ntawm lub nozzle yuav raug txo vim yog cov nyhuv throttling, uas tuaj yeem siv los tsoo cov ntaub ntawv kub.
Tam sim no, huab cua crushing thiab grading khoom yog ib qho irreplaceable ultra-fine ua khoom siv nyob rau hauv lub silicon carbide hmoov kev lag luam, noj cov huab cua crushing thiab grading system ua piv txwv, cov huab cua crushing thiab grading txheej txheem yog raws li nram no:
(1) Cov nyhuv ntawm kev muab qhab nia log thiab lub kaw lus cua ntim ntawm silicon carbide hmoov khoom
Raws li lub hauv paus ntsiab lus ntawm kev faib tawm, kev faib tawm ntawm silicon carbide hmoov pom tseeb yuav tsum tau txhim kho qhov ceev ntawm cov qhab nia ntawm lub log, theem ntawm kev sib tw log ceev txiav txim siab qhov loj ntawm lub zog centrifugal, thiab qhov loj ntawm lub kaw lus cua ntim cuam tshuam rau lub log. qhov loj ntawm qhov tsis kam ntawm cov khoom, nyob rau hauv txoj cai, ua kom cov khoom tau txais ntau npaum li centrifugal quab yuam ntau npaum li qhov ua tau thiab qhov tsawg kawg nkaus kuj.
Txhawm rau kom tau txais cov kev faib tawm meej ntawm SIC hmoov, nws tsis yog kev lag luam yooj yim kom yooj yim rau kev faib cov log nrawm, thiab nws yog ib qho tsim nyog yuav tsum tswj xyuas qhov kev faib ua feem ntawm cov huab cua thiab cov huab cua loj. Thaum lub kaw lus ua haujlwm nrog cov huab cua me me, kho qhov kev faib tawm lub log ceev yog qhov xav tau ntau dua rau kev hloov pauv ntawm qhov loj me. Txawm li cas los xij, qhov txo qis ntawm tag nrho cov huab cua ntim yuav ua rau txo qis hauv kev ua haujlwm, uas yog qhov tsis txaus ntseeg, yog li lub kaw lus yuav tsum ntsuas qhov zoo thiab qhov tsis zoo thiab xaiv qhov kev ua haujlwm zoo tshaj plaws.
(2) Qhov cuam tshuam ntawm txoj kev pub mis thiab dispersion ntawm raw khoom ntawm kev ua tau zoo ntawm cov khoom
Feem ntau siv vibration feeders thiab kauv feeders tsis tsuas yog tsis zoo ib yam thiab hnyav hnyav, tab sis kuj agglomerate thiab caking ncaj qha cuam tshuam rau kev faib cov nyhuv. Hauv kev tsim khoom, cov txheej txheem ntawm kev vibration feeder + kaw-tawm kiv cua + ntev raj roj conveying tuaj yeem siv los xyuas kom meej tias cov hmoov nkag mus rau hauv chav sib cais yog sib xws thiab kev noj ntau npaum li cas. Kev taw qhia ntawm peb cov huab cua los ntawm kev muab qhab nia sab nraum lub tsho ntxiv pab rau kev tawg ntawm cov hmoov zoo, uas ua rau cov khoom ua haujlwm ruaj khov thiab yooj yim rau cov neeg ua haujlwm ua haujlwm, thaum tseem ua kom cov khoom zoo. Nyob rau tib lub sijhawm, kom ntseeg tau tias cov roj-khoom muaj zog thiab zoo dispersion ntawm raw cov ntaub ntawv yog tus yuam sij los txhim kho cov kev faib tawm efficiency.
(3) Cov khoom ua haujlwm
Cov khoom siv silicon carbide hmoov tsim los ntawm lub tshuab cua tshuab thiab kev muab qhab nia tuaj yeem ua tau raws li qhov xav tau ntawm qhov loj me ntawm W14, W10, W7, WS thiab lwm yam khoom siv hmoov zoo hauv GB / T 2477-83 tus qauv siv hauv Tuam Tshoj txoj kev lag luam abrasive . Ntxiv mus, nws ua tau raws li qhov xav tau ntawm qhov loj me ntawm F1000, F1200, F2000 thiab lwm yam khoom hauv JIS 86001-1987 cov qauv kev lag luam rau cov hmoov abrasive siv rau kev sib sau ua ke, thiab cov hmoov zoo tawm los mus txog 85%.
Rau kev sib tsoo ultrafine ntawm silicon carbide, lub tshuab cua tshuab muaj qhov zoo ntawm kev ua haujlwm siab, tsis muaj hnav, siab tawm los thiab lwm yam, thiab tau siv dav hauv ntau cov khoom lag luam superhard hauv tsev thiab txawv teb chaws.
