1. Kev xaiv pob zeb diamond particle loj
Thaum lub pob zeb diamond loj yog ntxhib thiab ib leeg, lub taub hau taub hau yog ntse thiab kev ua haujlwm siab, tab sis lub zog khoov ntawm pob zeb diamond agglomeration txo.Thaum lub pob zeb diamond granularity zoo los yog sib xyaw, cov saw hniav lub taub hau muaj kev ua haujlwm siab tab sis tsis tshua muaj txiaj ntsig.Xav txog cov ntsiab lus saum toj no, 50/60 mesh pob zeb diamond loj yog tsim.
2. Kev xaiv ntawm pob zeb diamond faib concentration
Nyob rau hauv ib tug tej yam ntau yam, thaum lub pob zeb diamond concentration hloov ntawm qis mus rau siab, lub sharpness thiab txiav efficiency ntawm lub sawb maj mam txo, tab sis cov kev pab cuam lub neej yog maj mam ncua.Tab sis yog tias qhov concentration siab dhau lawm, cov hniav yuav ua npub.Siv cov concentration tsawg, coarse grain loj, efficiency yuav zoo dua.Kev siv cov khoom sib txawv ntawm cov cuab yeej lub taub hau hauv sawing, siv ntau qhov sib txawv (uas yog, hauv peb txheej lossis ntau txheej txheej ntawm cov qauv ntawm cov txheej txheem nruab nrab tuaj yeem siv los txo qis concentration), cov txheej txheem ntawm cov saw taub hau ua haujlwm ntawm kev tsim. ntawm qhov nruab nrab groove, conducive los tiv thaiv cov saw hniav pendulum, thiaj li los txhim kho qhov zoo ntawm pob zeb ua.
3. Xaiv lub zog pob zeb diamond
Lub zog ntawm pob zeb diamond yog qhov ntsuas tseem ceeb los xyuas kom meej qhov kev ua tau zoo.Lub zog siab dhau lawm yuav ua rau cov siv lead ua tsis yooj yim tawg, abrasive hais yog polished hauv kev siv, sharpness txo, ua rau cov cuab yeej deterioration;Thaum lub zog ntawm pob zeb diamond tsis txaus, nws yog ib qho yooj yim kom tawg tom qab muaj kev cuam tshuam thiab nyuaj rau dais lub luag haujlwm hnyav ntawm kev txiav.Yog li ntawd, kev siv zog yuav tsum raug xaiv hauv 130 ~ 140N.4. Kev xaiv ntawm kev sib khi theem
Qhov kev ua tau zoo ntawm cov saw hniav nyob ntawm qhov tsis tsuas yog nyob ntawm pob zeb diamond, tab sis kuj nyob ntawm qhov kev ua tau zoo tag nrho ntawm cov khoom sib xyaw uas yog tsim los ntawm kev sib xyaw kom zoo ntawm pob zeb diamond thiab binder.Rau marble thiab lwm yam pob zeb mos, cov cuab yeej cuab tam ntawm lub taub hau lub cuab yeej yog qhov tsawg, tuaj yeem xaiv tooj liab puag binder.Tab sis lub sintering kub ntawm tooj liab puag binder yog tsawg, lub zog thiab hardness yog tsawg, lub toughness yog siab, thiab lub zog sib txuas nrog pob zeb diamond yog tsawg.Thaum WC ntxiv, WC lossis W2C yog siv los ua cov pob txha hlau, nrog rau qhov tsim nyog ntawm cobalt los txhim kho lub zog, hardness thiab kev sib txuas cov yam ntxwv, thiab ib qho me me ntawm Cu, Sn, Zn thiab lwm yam hlau uas tsis tshua muaj melting point thiab hardness. ntxiv raws li lub sij hawm sib txuas.Qhov loj me me ntawm cov khoom siv tseem ceeb yuav tsum zoo dua 200 mesh, thiab qhov loj me ntawm cov khoom siv ntxiv yuav tsum zoo dua 300 mesh.
5. Kev xaiv cov txheej txheem sintering
Nrog rau qhov nce ntawm qhov kub thiab txias, qhov degree ntawm densification ntawm carcass nce, yog li lub zog dabtsi yog khoov.Txawm li cas los xij, nrog kev ncua sij hawm tuav, lub zog khoov ntawm cov pob zeb dawb paug thiab pob zeb diamond agglomeration thawj zaug nce thiab tom qab ntawd txo qis.Cov txheej txheem sintering ntawm 120s ntawm 800 ℃ tuaj yeem xaiv kom tau raws li qhov yuav tsum tau ua.
