Khoom Description

Silicon carbide muaj ob feem ntau siv ntau hom dub silicon carbide thiab ntsuab silicon carbide, ob qho tib si yog -SiC. ① Black silicon carbide muaj txog 95 feem pua SiC, nws qhov toughness siab dua ntsuab silicon carbide, feem ntau yog siv los ua cov ntaub ntawv uas tsis muaj zog tensile, xws li iav, ceramics, pob zeb, cov ntaub ntawv refractory, cam khwb cia hlau thiab non-ferrous hlau. Ntsuab silicon carbide muaj ntau dua 97 feem pua SiC, nws tus kheej-sharpening yog qhov zoo, feem ntau yog siv rau kev ua cov cemented carbide, titanium alloy thiab optical iav, tab sis kuj siv rau honing lub tog raj kheej liner thiab zoo sib tsoo high-speed steel cov cuab yeej. Tsis tas li ntawd, muaj cubic silicon carbide, uas yog cov txheej txheem tshwj xeeb ntawm daj ntsuab siv lead ua, siv los ua abrade rau bearing superfinishing, tuaj yeem ua rau qhov roughness ntawm Ra32 ~ 0.16 microns ua rau Ra{{9 }} 04 ~ 0.02 microns.

Silicon carbide vim muaj cov tshuaj lom neeg ruaj khov, siab thermal conductivity, me me thermal expansion coefficient, zoo hnav tsis kam, ntxiv rau abrasive, muaj ntau lwm yam kev siv, xws li: nrog ib tug tshwj xeeb txheej txheem rau silicon carbide hmoov coated nyob rau hauv lub puab phab ntsa. lub turbine impeller los yog lub tog raj kheej lub cev, tuaj yeem txhim kho nws qhov hnav tsis kam thiab txuas ntxiv lub neej kev pabcuam 1 ~ 2 zaug; Siv los ua cov khoom siv high-grade refractory, tshav kub tsis kam, me me, lub teeb yuag thiab siab zog, zoo zog txuag cov nyhuv. Qib qis silicon carbide (muaj li ntawm 85 feem pua SiC) yog cov deoxidizer zoo heev, uas tuaj yeem ua kom cov hlau ua kom nrawm, pab tswj cov tshuaj muaj pes tsawg leeg, thiab txhim kho cov hlau zoo. Tsis tas li ntawd, silicon carbide kuj tau siv dav hauv kev tsim hluav taws xob cua sov caij silicon carbon pas nrig.
