Hauv cov txheej txheem tsim khoom ntawm cov pob zeb siv hauv cov mines, cementcov nroj tsuag,thiab cov chaw tsim khoom sib sau ua ke, cov pob hlau ua haujlwm ua cov khoom siv sib tsoo tseem ceeb, uas tswj hwm kev sib tsoo zoo, cov nqi siv taukev tswj hwm,thiab lub neej ua haujlwm ntawm cov khoom siv. Cov neeg yuav khoom feem ntau siv qhov nyuaj ua qhov tseem ceeb thaum xaiv cov pob hlau, xav tias qhov nyuaj dua coj kev tiv thaiv kev hnav zoo dua thiab lub neej ua haujlwm ntev dua. Txawm li cas los xij, kev xyaum ua haujlwm ntev ua pov thawj tias kev nrhiav kev nyuaj ntau dhau yogtsis ua haujlwm zoo. Qhov nyuaj tsuas yog ib qho cim qhia kev ua tau zoo ntawm cov pob hlau. Kev tsis quav ntsej txog qhov tawv, cov yam ntxwv ntawm cov khoom siv thiab cov xwm txheej ua haujlwm ntawm lub zeb thaum tsuas yog ua kom qhov tawv ntxiv yuav ua rau cov pob tawg ntau dhau, ua rau lub liner hnav sai dua thiab txo qhov muaj peev xwm tsim khoom. Lub hauv paus ntsiab lus tseeb ntawm kev xaiv pob hlau yog nyob rau hauv kev sib npaug ntawm qhov tawv thiab qhov tawv raws li cov xwm txheej ua haujlwm tiag tiag kom ua tiav cov txiaj ntsig kev lag luam tag nrho.
IICov Kev Tsis Zoo Uas Ua Los Ntawm Kev Nyuaj Siab Dhau Dhau
(1)Kev Txo Qhov Toughness Ua Rau Muaj Kev Tawg Thiab Chipping
Qhov tawv thiab tawv ntawm cov pob hlau ua raws li kev sib pauv tawm. Thaum Brinell hardness tus nqi nce siab, qhov tawv sab hauv ntawm cov hlau poob qis tas li. Thaum lub sijhawm ua haujlwm ntawm lub pob, kev sib tsoo thiab kev nias ntawm cov pob hlau thiab ntawm cov pob hlau thiab cov ntaub. Cov pob hlau tawv tab sis tsis tawv tsis tuaj yeem tiv taus kev cuam tshuam ntau zaus, ua rau qhov chaw tev tawm, tawg thiab tawg. Cov pob tawg sib xyaw nrog cov khoom siv raw thiab poob cov haujlwm sib tsoo. Nws ua rau kev siv pob hlau ntau ntxiv thiab nce cov nqi zog ua haujlwm los ntawm kev rov ua dua pob ntau zaus.
(2)Kev Siv Cov Kab Hlau Sai Dua Thiab Cov Nqi Kho Khoom Siv Siab Dua
Cov pob hlau tawv tawv muaj qhov ruaj khov heev. Lawv qhov cuam tshuam ntse ua rau cov ntaub thaiv kab sib tsoo thiab ua rau lub voj voog hloov pauv luv dua. Cov lag luam yuav tsum nres kev tsim khoom rau kev hloov pauv khoom tsis tu ncua. Sib nrug ntawm cov nuj nqis yuav khoom ntxiv, lub sijhawm tsim khoom poob qis ua rau cov khoom poob thiab nce cov nqi ua haujlwm dav dav tsis ncaj qha..
(3)Teeb Meem Rov Qab Los Thiab Kev Sib Tsoo Ua Rau Kev Sib Tsoo Tsis Zoo
Cov pob hlau tawv tuaj nrog kev ywj pheej ntau dua. Lawv feem ntau rov qab los thiab plam thaum poob rau ntawm cov khoom siv. Lub zog cuam tshuam zoo raug pov tseg, ua rau kev ua haujlwm tsis muaj zog. Kev sib tsoo tsis txaus ua tsis tau raws li qhov xav tau ntawm cov khoom seem thiab rub cov khoom tsim tawm ntawm tag nrho cov kab ntau lawm.
IIIKev Sib Tw Kom Muaj Peev Xwm ntawm Qhov Hardness thiab Toughness ntawm Pob Hlau Raws Li Cov Xwm Txheej Ua Haujlwm
(1)Kev Xaiv Raws Li Cov Khoom Raw
Qhov nyuaj ntawm cov khoom siv yog qhov tseem ceeb tshaj plaws. Cov pob hlau uas muaj zog heev raug siv rau cov khoom siv raw xws li hlau ore thiab granite kom lav qhov hnav tsis kam. Rau cov khoom mos xws li limestone thiab av nplaum, yuav tsum muab qhov tseem ceeb rau qhov muaj zog dua nrog qhov nyuaj qis dua kom tiv thaiv kev tawg ntawm lub pob thaum muaj kev cuam tshuam. Qhov loj ntawm cov khoom noj pub mis kuj yuav tsum tau xav txog. Cov khoom siv raw loj tsim cov khoom hnyav, uas xav tau kev txhim kho lub pob hlau tawv.
(2)Kev Kho Kom Zoo Dua Raws Li Cov Txheej Txheem Sib Tsoo
Cov theem sib tsoo ntxhib siv lub zog cuam tshuam los tsoo cov pob loj nrog lub nra hnyav, yog li cov pob hlau tawv yuav tsum tau muab tso ua ntej kom tsis txhob tawg. Cov theem sib tsoo zoo nyob ntawm kev sib txhuam, qhov twg cov pob hlau tawv dua yog qhov nyiam rau kev tiv thaiv kev hnav zoo dua. Ntxiv mus, kev sib tsoo qhuav thiab kev sib tsoo ntub ua qhov sib txawv. Kev xeb los ntawm dej noo hauv kev sib tsoo ntub kuj xav tau kev ua haujlwm tiv thaiv kev xeb ntawm cov hlau.
(3)Kev Sib Tw Nrog Cov Kev Ua Haujlwm ntawm Pob Zeb
Qhov ceev ntawm lub tshuab tig, qhov loj ntawm lub tog raj kheej thiab lub peev xwm thauj khoom ntawm lub pob kuj cuam tshuam rau kev xaiv lub pob hlau. Qhov ceev ntawm kev tig siab dua ua rau muaj kev sib tsoo ntau zaus thiab xav tau kev tawv zoo dua. Cov tshuab sib tsoo pob loj tsim cov kev cuam tshuam muaj zog dua los ntawm qhov siab poob siab, qhov twg cov pob hlau uas muaj zog thiab tsis tawv yog txwv tsis pub.
IVXaus Lus
Hauv kev xaus lus, qhov nyuaj yuav tsis yog qhov ntsuas nkaus xwb rau kev yuav cov pob hlau. Cov khoom siv sib tsoo zoo xav tau qhov sib npaug ntawm qhov nyuaj thiab qhov tawv. Cov neeg yuav khoom yuav tsum tshem tawm qhov kev xav txog qhov nyuaj xwb. Cov khoom siv pob hlau thiab kev teeb tsa qhov nyuaj yuav tsum tau kho raws li qhov nyuaj ntawm cov khoom siv raw, cov txheej txheem sib tsoo thiab cov txheej txheem zeb. Los ntawm kev txo cov pob tawg, tiv thaiv cov khoom siv zeb thiab tsa cov zis sib tsoo, cov lag luam tuaj yeem txiav cov nqi mus sij hawm ntev thiab txhim kho kev ua haujlwm ntau lawm.
