Khoom Description
Dub silicon carbide hmoov yog cov khoom siv tseem ceeb, nws cov khoom tseem ceeb yog silicon thiab carbon, thiab nws cov tshuaj formula yog SiC. Cov khoom siv no muaj ntau yam kev siv hauv ntau qhov chaw vim nws lub cev thiab tshuaj lom neeg tshwj xeeb. Lub Mohs hardness ntawm dub silicon carbide hmoov yog siab li 9. Cov qauv siv lead ua ntawm cov xim dub silicon carbide ruaj khov, thiab nws tuaj yeem tswj xyuas lub cev zoo thiab tshuaj lom neeg ruaj khov ntawm qhov kub thiab txias. Nws tuaj yeem ua haujlwm ib txwm nyob ntawm qhov kub ntawm 1850 degree thiab tswj kev ua haujlwm zoo ntawm 1400 degree.
Nyob rau hauv qhov kub thiab txias, ib txheej ntawm silicon dioxide zaj duab xis yuav tsim nyob rau saum npoo ntawm dub silicon carbide hmoov hais, uas zoo tiv thaiv oxidation ntawm silicon carbide thiab resists yaig ntawm muaj zog acids thiab alkalis, yog li nws muaj zoo heev corrosion kuj thiab high-temperature. oxidation tsis kam. Dub silicon carbide hmoov muaj cov thermal conductivity zoo thiab tuaj yeem tawg sai sai. Nyob rau tib lub sijhawm, nws cov thermal expansion coefficient tsis tshua muaj txiaj ntsig pab tswj kev ruaj ntseg ntawm cov khoom ntawm qhov kub thiab txias.
Dub silicon carbide hmoov yog dav siv rau kev sib tsoo hlau thiab cov ntaub ntawv tsis yog hlau, xws li alloys, silicon wafers, ceramics, jade, thiab lwm yam, tshwj xeeb tshaj yog nyob rau lub sij hawm uas yuav tsum tau nruj me ntsis rau saum npoo roughness. Dub silicon carbide hmoov tuaj yeem muab qhov xav tau particle loj raws li tus txheej txheem. Raws li cov hmoov zoo nrog cov tawv tawv heev, cov hmoov dub silicon carbide feem ntau ntxiv rau cov txheej, cov resins, cov yas tshwj xeeb, lossis lwm cov ntaub ntawv sib xyaw los txhim kho cov hnav tsis kam ntawm cov ntaub ntawv, thiab nws muaj txiaj ntsig zoo rau lub zog, corrosion kuj thiab siab. -kub tsis kam ntawm cov khoom. Cov hmoov dub silicon carbide tuaj yeem siv los ua cov txheej txheem kub tiv thaiv corrosion thiab thermal rwb thaiv tsev cov ntaub ntawv, uas ua lub luag haujlwm hauv kev tiv thaiv hluav taws kub thiab tiv thaiv hluav taws. Nyob rau tib lub sijhawm, nws tseem tuaj yeem siv los ua cov khoom siv raw rau kev tiv thaiv corrosion mortar thiab siv rau hauv thermal, hluav taws xob thiab lwm yam lag luam. Tom qab kev lag luam ceramics yog tov nrog dub silicon carbide hais, lawv tuaj yeem ua rau sintered silicon carbide ceramics los txhim kho qhov ntom thiab kev ua tau zoo ntawm silicon carbide ceramics.
Dub silicon carbide hmoov yog cov khoom siv tseem ceeb rau cov khoom siv abrasive xws li dej xuab zeb thiab roj hmab sib tsoo log. Nws yog siv los tsim ntau yam khoom siv silicon carbide ceramic, xws li cov cuab yeej abrasive, txee thiab saggers hauv kilns rau firing ceramic khoom, silicon carbide cib rau ntsug lub tog raj kheej distillation furnaces nyob rau hauv zinc smelting kev lag luam, thiab lwm yam. steel, uas yog, raws li deoxidizer rau steelmaking thiab cam khwb cia hlau qauv txhim kho. Tib lub sijhawm, nws tseem tuaj yeem siv los ua cov khoom siv raw rau kev tsim silicon tetrachloride.
