2) Daim ntaub ntawv tseem ceeb:

• Ntxhib thiab hnyav {{- Worityle sib tsoo: xws li Tu Hlau Hlau Inpots thiab Deburring Castings.
• Kev Siv Khoom Siv Hluav Taws Xob: Sib tsoo dav dav - hom phiaj cuab yeej xws li tig cov cuab yeej, tho, thiab milling cutters.
• Precision sib tsoo cov hlau thiab alloy steel: cylindric sib tsoo, nto sib tsoo, kev sib tsoo nto, thiab lwm yam.
• Sib tsoo ntawm high -} lub zog nrum hlau.

 

3) hom khoom:

• Xim av Corundum: Feem ntau siv thiab ntau yam khoom siv, siv rau ntxhib thiab semi- tiav kev sib tsoo.
• Dawb corundum: me ntsis nyuab thiab ntau nkig, siv rau kev sib tsoo zoo thiab tshuab sib tsoo, ua tiav tau zoo dua saum npoo.
• Chrome Corundum: Ntau tawv dua li dawb corundum, siv rau kev sib tsoo thiab ua kev sib tsoo, ua tiav tau zoo dua saum npoo.

 

2. Silicon Carbide Sib Tsoo Log

Silicon Carbide yog tus txiv neej - Ua cov ntxhia ua rau muaj kev txo qis ntawm silicon dioxide thiab carbon nyob rau hauv lub siab- kub hluav taws xob rauv taws. Nws yog qhov nyuaj thiab Sharper tshaj Corundum, tab sis kuj ntau nkig.

 

1) Cov Qauv Tseem Ceeb:

• Huab hardness thiab ntse: cov abrasive nplej yog ntse heev, nrog kev txiav tawm qis thiab siab sib tsoo efficiency.
• Zoo thermal conductivity: Pab sai sai sib tsoo tshav kub, txo txoj kev pheej hmoo ntawm thermal kev puas tsuaj rau lub workpiece.
• Tshuaj lom neeg ruaj khov: tiv qhov kev tawm tsam nrog cov hlau ferrous ntawm qhov kub.

 

2) Daim ntaub ntawv tseem ceeb:

• Kev sib tsoo thiab hliav Carbide: Qhov no yog qhov tseem ceeb tshaj plaws rau silicon carbide sib tsoo log (tshwj xeeb tshaj yog ntsuab silicon carbide).
• Sib tsoo tsis - ferrous hlau: xws li txhuas, tooj liab, thiab Babbitt. Corundum sib tsoo cov log nrawm nrawm nrawm vim tias cov khoom muag thiab ductile cov khoom ntawm cov ntaub ntawv no, thaum carbide sib tsoo lub log zoo txiav thiab tswj kom huv si.
• Sib tsoo tsis- cov khoom siv hlau: txiav thiab sib tsoo iav, ceramics, thiab pob zeb.
• Kev sib tsoo kom zoo ntawm cam khwb cia hlau: tshwj xeeb tshaj yog thaum muaj kev ua tiav zoo heev.
• Ua cov khoom siv xws li roj hmab, tawv, thiab plastics.

 

3) hom khoom:

• Silicon Carbide: ntau yam ntau, siv rau kev sib tsoo cam khwb cia hlau, tsis {} ferrous hlau, thiab tsis- nws cov ntaub ntawv metallic.
• Ntsuab silicon carbide: curity curity, siab dua hardness, thiab tsawg dua nkig. Tshwj xeeb yog tsim rau kev sib tsoo zoo ntawm cov ntaub ntawv nyuaj thiab cov kab mob brittle xws li carbide, iav kho qhov muag, thiab ceramics.

 

 

3 Lwm qhov kev txiav txim siab tseem ceeb

Ntxiv rau cov hom kev sib tsoo, cov cwj pwm sib tsoo hauv qab no yog qhov tseem ceeb thiab, ua ke nrog cov hom abrasive, txiav txim siab cov kev ua tau zoo ntawm cov log sib tsoo:

1) grit loj:

• Kev ntxhib ntxig (piv txwv li, 36 #) yog siv rau kev sib tsoo ntxhib thiab tsim cov kev tshem tawm siab; Zoo grit (piv txwv li, 120 #) yog siv rau kev sib tsoo zoo thiab ua rau cov npoo du.

 

2) Hardness:

• Qhov no yog hais txog lub zog ntawm txoj kev sib khi uas muaj cov qoob loo abrasive. Kev sib tsoo nyuaj yog qhov haum rau kev sib tsoo cov ntaub ntawv mos kom tiv thaiv thaum ua kom rov qab los; Mos sib tsoo cov log yog qhov haum rau kev sib tsoo cov ntaub ntawv nyuaj los txhawb tus kheej- hliav.

 

3) Bond:

• Vitrified Daim Ntawv Cog Lus: Qhov feem ntau siv, nrog lub zog siab, ua cua sov thiab corrosion tsis kam, haum rau ntau yam ntawm kev sib tsoo cov haujlwm.
• Resin Bond: elasticity zoo thiab cov nyhuv polishing. Siv rau kev txiav, ntxhib sib tsoo, thiab kom tiv thaiv kev kub nyhiab.
• Roj Hmab Nyiaj Txiag: Muaj lub zog thiab elasticity. Siv rau kev qhia cov log hauv kev sib tsoo hauv nruab nrab thiab cov log rau txiav cov ntawv nyias nyias.

 

4) Microstructure:

Qhov no yog hais txog qhov ntim piv ntawm cov nplej zom, daim ntawv cog lus, thiab pores.

• Tight cov ntaub so ntswg muaj cov kev sib tsoo siab, tab sis yog ib txwm ua rau cov cua sov;
• Cov ntaub so xoob tsis yooj yim rau txhaws thiab muaj cov cua sov dissipation, thiab yog qhov tsim nyog rau cov muag muag, tawv, thiab yooj yim txhaws cov ntaub ntawv.
