Silicon Carbide SIC
1. khoom muaj ncauj lus kom ntxaws
Dub siv lead ua silicon carbide nrog qhov siab tsim nyob rau hauv peb cov nroj tsuag yog tsim los ntawm cov siab huv si quartz xuab zeb thiab roj av coke. Cov khoom lag luam tas li ntawm kub txog li 2500C hauv hluav taws xob hluav taws xob. Cov khoom lag luam muaj qhov siab hardness zoo thermal endurance hnav tsis kam, hluav taws xob tsis kam, thermal poob siab, thiab zoo hluav taws xob thiab thermal conductivity, thiab dav siv hauv engineering, chemistry, hluav taws xob, metallurgy thiab kev tiv thaiv kev lag luam. Peb lub tuam txhab tuaj yeem tsim cov ntau thiab tsawg ntawm silicon carbide, raws li lub teb chaws thiab thoob ntiaj teb tus qauv GB, ISO, ANSI, FEPA, JIS, thiab lwm yam.
Silicon carbide (SiC), tseem hu ua carborundum, yog qhov sib xyaw ua ke ntawm silicon thiab carbon nrog cov tshuaj lom tshuaj SiC. Nws tshwm sim hauv cov xwm yam li tsis tshua muaj cov ntxhia pob zeb moissanite. Synthetic silicon carbide hmoov tau tsim-loj txij li xyoo 1893 rau siv raws li kev ua kom zoo. Cov nplej ntawm silicon carbide tuaj yeem sib koom ua ke los ntawm sintering los ua cov ntaub ntawv tawv tawv hnyav uas tau siv dav hauv cov ntawv thov uas yuav tsum muaj qhov kev ua siab ntev, xws li lub tsheb nres, cov tsheb sib tsoo thiab cov phaj ceramic hauv cov tsho khiab plaub. Kev siv hluav taws xob ntawm silicon carbide xws li lub teeb ci hluav taws xob (LEDs) thiab cov ntsuas hauv hluav taws xob thaum ntxov tau qhia ua ntej puag ncig xyoo 1907. SiC siv rau hauv cov khoom siv hluav taws xob hluav taws xob uas ua haujlwm ntawm qhov kub lossis hluav taws xob siab, lossis ob qho tib si. Loj loj ntim khoom ntawm silicon carbide tuaj yeem loj hlob los ntawm Lely txoj kev; lawv tuaj yeem txiav rau hauv lub pov haum hu ua synthes moissanite. Silicon carbide nrog thaj tsam siab tuaj yeem tsim los ntawm SiO2 uas muaj nyob hauv cov khoom cog.
2.Qhov kev siv tswv yim
(1) Lub tshuab hluav taws xob loj dua, lub sijhawm yaj ntev dua, ua rau cov khoom siv ntau dua qub, muaj cov khoom siv loj dua, ua kom muaj ntau dua thiab ua kom lub cev tsis huv ua rau Silicon carbide.
(2) Cov cwj pwm ntawm Silicon carbide: Cov tawv tawv tawv ntev, lub neej ntev.
(3) Tshuaj txhuam thiab ntxuav cov dej kom huv.
(4) Kev kho tshwj xeeb rau Silicon carbide tau txais kev coj dawb huv dua, zoo dua lub nruj dua, thiab kev sib tsoo zoo dua.
3.Application
Silicon carbide tuaj yeem siv los ua cov khoom siv metallurgical deoxidizer thiab cov khoom kub tiv thaiv hauv kev sib tsoo.
Silicon carbide kuj tseem siv tau los ua cov khoom siv ua kom tsis zoo, uas tuaj yeem siv los ua cov cuab yeej ua kom puas, xws li kev sib tsoo cov log, roj av, sib tsoo lub taub hau thiab lwm yam.
Silicon carbide yog qhov tshiab ntawm kev tiv thaiv cov hlau loj deoxidizing tus neeg sawv cev thiab zoo tshaj plaws thermal insulating agent.it yog siv rau deoxidizing. Kev siv tshuaj yog 14kg / t tuaj yeem ua rau hluav taws xob siv hluav taws xob kom txo tau 15-20kw / teev thiab sijhawm kom txo qis li 15-20min rau ib lub cub tawg kom nce cov khoom tsim khoom tau txog 8-10%.
