Yuav ua li cas xaiv ntu (cov lus qhia yooj yim rau xaiv ntu)

a) Yog li hu ua ntu, nws hais txog ntu pob zeb diamond . Nyob rau hauv masonry, sawing, txiav, sib tsoo, thiab polishing ua hauj lwm yog tag nrho cov ua siv cov xwm ntawm pob zeb diamond, xws li, nws siab hardness, siab siv, thiab siab wearability. Qhov khoob yog siv los ua tus tuav.

Cov pob zeb diamond ntu feem ntau raug nqi 12.5 feem pua ​​​​ntawm cov nqi txiav - pob zeb, thiab rau lub hom phiaj ntawm lawv cov nqi siab, tsim nyog siv thiab xaiv lawv yog

tseem ceeb dua.

b) Qhov dav ntawm ntu tuaj yeem muab faib ua pawg los ntawm qhov yuam kev band .Qhov kev ua yuam kev band yuav tsum tswj tsis pub dhau 0.05mm hauv tib lub ntsej muag .

c) Thaum txiav pob zeb, qhov ua haujlwm tiag tiag ntawm lub pob zeb yog pob zeb diamond siv lead ua, thaum cov hlau sib txuas yog siv los tuav lawv ua ke. Pob zeb diamond muaju yuav raug nthuav tawm ntawm qhov siab, feem ntau ntawm 20 feem pua ​​-60 feem pua ​​​​qhov siab ntawm cov siv lead ua, nws nyob ntawm pob zeb. Pob zeb sib txawv muaj

qhov sib txawv yuav tsum tau rau qhov qis tshaj qhov siab nthuav tawm.

d) Lub kerf txiav los ntawm cov hniav yog qhov tshwm sim los ntawm tag nrho cov pob zeb diamond siv lead ua 'txiav.

e) Cov hniav durability yog dab tsi, uas yog cov hniav lifespan? Nws yog qhov kawg

acreage (square meter) ntawm lub pob zeb txiav los ntawm cov hniav los ntawm nws thawj txiav mus rau nws kawg txiav (thaum nws pob zeb diamond txheej hnav tawm .)

f) Qhov zoo tshaj plaws ntawm cov saw hniav yog ntsuas los ntawm qhov chaw 's feature ntawm lub pob zeb txiav. nrog rau nws cov theem mob, smoothness, thiab avoi seev cev ntawm desquamation . Cov theem tsis zoo, coarseness, thiab desquamation tag nrho piav qhia tsis zoo ntawm cov saw hniav.

g) Qhov kev ua tau zoo yog qhov chaw ntawm cov pob zeb txiav hauv ib chav tsev ntawm lub sijhawm. Nws yog lub ntsiab Performance index rau hniav lub peev xwm, nws yog cuam tshuam los ntawm txiav qhov tob, txiav ceev thiab txiav lub sij hawm.

h) Plaub yam tseem ceeb ntawm kev txiav kev ua haujlwm, raws li hauv qab no

I . Pob zeb diamond concentration , nws txiav txim siab txiav lifespan . Siab dhau los yog qis dhau yuav tawm tsam qhov kev txiav txim siab. Nws tus nqi yuav tsum yog qhov sib npaug ntawm cov neeg siv khoom xav tau thiab kev lag luam.

li .Bond , nws yog txiav txim los ntawm pob zeb hom, pob zeb concentration, parameter ntawm saw machinery thiab txias txias, tej zaum tus neeg teb xov tooj qhov kev ua tau zoo yuav tsum tau txiav txim siab.

lii . Pob zeb diamond grit , nws tus nqi nyob ntawm qhov hardness ntawm cov pob zeb txiav thiab lwm yam. Qhov nyuaj ntawm lub pob zeb txiav, qhov me me ntawm cov grit yog thiab lub zog ntau dua qhov txiav yog .

Iv. Linear ceev, lub softer lub pob zeb yog, qhov siab dua L - ceev yog . Lub pob zeb nyuaj dua, qhov qis dua L-ceev yog .
