ABRASIVES: Qee qhov kev paub yooj yim tuaj yeem ua qhov sib txawv loj

Abrasives yog ib lo lus dav dav rau abrasives thiab abrasives, nrog rau cov khoom abrasive thiab cov khoom abrasive.

 

Abrasive khoom feem ntau muab faib ua ob pawg: corundum abrasives thiab silicon carbide abrasives. Tshwj xeeb, muaj cov hauv qab no hom:

 

1.Brown corundum abrasive

Lub ntsiab tivthaiv yog Al2O3, uas muaj nruab nrab hardness, siab toughness, ntse hais, kuj tsis tshua muaj nqi, thiab yog haum rau ua hlau nrog siab tensile zog. Microcrystalline corundum abrasives thiab dub corundum abrasives yog ob qho tib si derivatives.

 

2.White corundum abrasive

Nws hardness yog me ntsis siab dua xim av corundum, tab sis nws toughness yog tsis zoo. Nws yog ib qho yooj yim los txiav rau hauv lub workpiece thaum sib tsoo. Nws muaj qhov zoo ntawm tus kheej-sharpening, tsawg tshav kub tiam, muaj zog sib tsoo muaj peev xwm thiab kev ua haujlwm siab. Chrome corundum abrasive yog nws cov derivative.

 

3. Ib leeg siv lead ua corundum abrasive

Nws cov khoom yog tsim los ntawm ib qho siv lead ua ib leeg thiab muaj qhov zoo ntawm ntau cov ntug txiav, siab hardness thiab toughness, muaj zog sib tsoo muaj peev xwm, thiab sib tsoo kub tsawg. Qhov tsis zoo yog tias tus nqi tsim khoom yog siab thiab cov zis tawm tsawg, yog li tus nqi kuj tseem siab. . Zirconium corundum abrasive kuj yog siv lead ua sib xyaw nrog me ntsis qis hardness, finer siv lead ua loj thiab zoo hnav tsis kam.

 

4.Silicon carbide abrasives

Dub silicon carbide abrasives, ntsuab silicon carbide abrasives, cubic silicon carbide abrasives, cerium silicon carbide abrasives, thiab lwm yam. belongs rau silicon carbide abrasives. Cov khoom tseem ceeb yog silicon carbide SiC, uas muaj siab hardness, siab brittleness, ntse abrasive nplej, zoo thermal conductivity, thiab hnav tsis kam. Muaj zog dua, tsim nyog rau kev ua cov tawv tawv thiab nkig hlau thiab cov khoom tsis yog hlau.

 

Abrasive cov cuab yeej feem ntau suav nrog ob pawg: cov cuab yeej abrasive zoo tib yam thiab cov khoom siv tawv tawv tawv tawv.

1.Ordinary abrasives xa mus rau abrasives ua los ntawm cov saum toj no-hais zoo abrasives

Raws li daim ntawv cog lus abrasive, nws tuaj yeem muab faib ua cov khoom sib txuas thiab cov coated abrasives, thiab raws li cov ntaub ntawv sib txawv, nws tuaj yeem muab faib ua ceramic abrasives, resin abrasives, roj hmab abrasives, abrasives thiab lwm yam series.

2.Superhard khoom sib tsoo cov cuab yeej

Feem ntau siv cov ntaub ntawv zoo xws li cov hmoov hlau, hlau oxide lossis CBN ua cov khoom ntim, cov khoom siv zoo tib yam (xws li Al2O3, SiC, thiab lwm yam) tuaj yeem muab ntxiv kom tsim nyog, thiab cov cuab yeej abrasive ua los ntawm resin daim ntawv cog lus, daim ntawv cog lus ceramic lossis hlau daim ntawv cog lus.
