Kev xaiv ntawm abrasives mas nyob ntawm cov khoom ntawm workpiece thiab txoj kev kho cua sov.
a. Thaum sib tsoo cov ntaub ntawv nrog lub zog loj tensile lub zog, siv abrasives nrog high toughness.
b. Rau cov ntaub ntawv nrog qis sib tsoo hardness thiab loj elongation, siv ntau brittle abrasives.
c. Thaum sib tsoo cov ntaub ntawv nyuaj, siv cov khoom siv tawv tawv.
d. Siv abrasives uas tsis raug rau cov tshuaj lom neeg hauv cov khoom uas tab tom ua haujlwm.
Cov tshuaj lom neeg uas siv ntau tshaj plaws yog xim av xim av corundum (A) thiab dawb corundum (WA), tom qab ntawd los ntawm cov xim dub silicon carbide (C) thiab ntsuab silicon carbide (GC). Lwm qhov siv feem ntau yog chromium corundum (PA) thiab ib leeg siv lead ua corundum (SA). , Microcrystalline corundum (MA), zirconium corundum (ZA).
Xim av corundum sib tsoo lub log: Brown corundum muaj lub siab tawv thiab tawv, thiab yog qhov haum rau kev sib tsoo hlau nrog lub zog siab, xws li carbon hlau, hlau tsis sib haum, malleable cam khwb cia hlau, tawv tooj liab, thiab lwm yam Qhov no abrasive muaj kev sib tsoo zoo thiab dav adaptability. Cov. Nws yog feem ntau siv rau kev sib tsoo nrog lub npoo loj. Nws yog qhov pheej yig thiab tuaj yeem siv dav.
Dawb corundum sib tsoo lub log: Lub hardness ntawm dawb corundum yog me ntsis siab dua ntawd ntawm xim av corundum, thiab qhov nyuaj yog qis dua li ntawm xim av corundum. Thaum lub sij hawm sib tsoo, cov nplej pob zeb tawg lawm yooj yim tawg. Yog li no, qhov sib tsoo kub yog qhov me me, thiab nws tsim nyog rau kev tsim precision-tawv steel, siab carbon steel, Cov hlau loj thiab sib tsoo lub log rau kev sib tsoo cov phab ntsa nyias nyias siv nyiaj ntau dua li xim av corundum.
Dub Silicon Carbide Log: Dub silicon carbide yog nkig thiab ntse, nrog lub siab tawv dua li dawb corundum, haum rau kev sib tsoo cov ntaub ntawv nrog qis zog lub zog, xws li cam khwb cia hlau, tooj dag, txhuas thiab cov ntaub ntawv refractory.
Ntsuab silicon carbide sib tsoo lub log: Ntsuab silicon carbide muaj qhov nyuaj dua thiab brittleness dua li dub silicon carbide, ntse abrasive hais thiab zoo thermal conductivity. Nws yog qhov tsim nyog rau kev sib tsoo cov ntaub ntawv nyuaj thiab nkig zoo xws li cov cemented carbide, iav kho qhov muag thiab ceramics.
Chrome corundum sib tsoo lub log: haum rau kev sib tsoo cov khoom ua haujlwm nrog cov txheej txheem ua haujlwm siab xws li cov cuab yeej txiav, ntsuas cov cuab yeej, ntsuas thiab xov.
Ib leeg siv lead ua corundum sib tsoo lub log: haum rau kev sib tsoo stainless hlau, high-vanadium high-speed steel thiab lwm yam ntaub ntawv nrog lub siab tawv thiab siab hardness thiab workpieces uas yooj yim rau deform thiab hlawv.
