Hauv cov xwm txheej kev lag luam xws li kev khawb av thiab kev ua cov ntaub ntawv hauv tsev, lub khob sib cais cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom siv ua haujlwm tau zoo, lub luag haujlwm rau kev faib khoom sib xws thiab kev taw qhia ntawm cov ntaub ntawv, thiab nyiaj dhau qhov cuam tshuam, kev sib txhuam, thiab cov xwm txheej ua haujlwm nyuaj ntawm cov ntaub ntawv nyuaj rau lub sijhawm ntev. Nrog rau kev txhim kho cov thev naus laus zis khoom siv,silicon carbideCov khoom sib cais tau maj mam hloov cov khoom sib cais alumina ib txwm muaj thiab dhau los ua qhov kev xaiv zoo tshaj plaws rau cov lag luam tsim khoom ruaj khov. Nws cov txiaj ntsig feem ntau pom tseeb hauv peb qhov tseem ceeb.
Cov khoom siv tiv taus hnav tau zoo heev, ua rau lub neej ua haujlwm ntev dua
Qhov yuav tsum tau ua ntawm lub khob sib cais cov khoom siv yog kom tiv taus kev yaig thiab kev hnav ntawm cov khoom siv, thiab qhov nyuaj yog qhov tseem ceeb rau kev hnav tsis kam. Qhov nyuaj ntawm silicon carbide yog siab dua li ntawm aluminium oxide, ib yam li muab "pob zeb diamond armor" rau ntawm lub khob pub mis. Thaum ua cov khoom siv tawv xws li granite thiab cov pob zeb dej ntws tas li, lub khob sib cais alumina yuav raug hnav thiab deformation ntawm qhov chaw, ua rau muaj kev txo qis ntawm kev hloov pauv thiab xav tau kev kaw thiab hloov pauv ntau zaus; Lub khob faib silicon carbide tuaj yeem tswj tau qhov chaw kom ruaj khov ntev, txo kev siv khoom siv, ua rau cov kab ntau lawm khiav tau zoo dua, thiab txo qhov zaus hloov pauv ntawm qhov chaw.
Kev hloov kho tau rau qhov chaw ib puag ncig hnyav, kev ruaj khov yam tsis muaj "poob ntawm cov saw hlau"
Cov xwm txheej hnyav xws li qhov kub hloov pauv thiab cov kua qaub-base hauv kev tsim khoom lag luam xav tau kev kam rau siab rau lub khob sib cais. Silicon carbide muaj qhov tiv taus kub zoo heev, thiab tuaj yeem tso cua sov sai sai txawm tias muaj kev hloov pauv kub sai, ua rau nws tsis yooj yim tawg; Aluminium oxide yooj yim tawg vim muaj kev ntxhov siab thermal hauv qhov kub siab lossis qhov kub sib txawv ntau zaus. Tsis tas li ntawd, silicon carbide muaj kev tiv taus cov xov xwm corrosive xws li cov kua qaub thiab alkalis muaj zog. Hauv cov xwm txheej ua haujlwm nyuaj xws li kev lag luam tshuaj lom neeg thiab hlau, nws ruaj khov dua li alumina sib cais cones thiab yuav tsis ua rau kev ua haujlwm poob qis lossis kev puas tsuaj ntxov ntxov vim yog xeb.
Tus nqi tag nrho zoo dua thiab kev txuag nyiaj mus sij hawm ntev yam tsis tas siv zog
Rau cov lag luam, kev xaiv cov khoom siv tsis yog tsuas yog nyob ntawm tus nqi yuav khoom pib xwb, tab sis kuj nyob ntawm tus nqi ntev. Txawm hais tias tus nqi yuav khoom pib ntawm silicon carbide dividing cones siab dua li ntawm alumina me ntsis, ua ke nrog lawv lub neej ntev, tus nqi ntawm kev hnav thiab rhuav ntawm cov khoom siv ib lub sijhawm raug txo qis heev. Qhov tseem ceeb tshaj, vim tsis txaus hnav thiab tiv taus kub, lub alumina separation cone yuav tsum tau kaw tas li rau kev hloov pauv, uas tsis yog tsuas yog ua rau tus nqi ntawm kev hloov pauv tes xwb, tab sis kuj ua rau kev cuam tshuam ntawm cov kab ntau lawm thiab kev poob ntau lawm zais cia; Lub silicon carbide sorting cone tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev, txo qhov zaus ntawm lub sijhawm tsis ua haujlwm, thiab txo cov nqi ob npaug ntawm kev saib xyuas tes thiab kev cuam tshuam ntawm kev tsim khoom. Kev siv ntev tuaj yeem txuag tau ntau cov nuj nqis rau cov lag luam.
Txij li kev ua tau zoo mus rau tus nqi, cov khoom sib cais silicon carbide tau ua pov thawj tias muaj txiaj ntsig zoo dua li cov khoom sib cais alumina. Hauv kev nrhiav kev tsim khoom zoo, txuag hluav taws xob, thiab ruaj khov niaj hnub no, hom kev xaiv khoom siv no uas vam khom kev hloov kho khoom siv tsis tsuas yog txhim kho kev ruaj khov ntawm cov kab ntau lawm, tab sis kuj coj cov txiaj ntsig kev lag luam rau cov tuam txhab, ua qhov kev xaiv pheej yig dua thiab ntse hauv kev tsim khoom lag luam.
