Nws yog dav siv nyob rau hauv cov xuab zeb thiab gravel aggregate ntau lawm, tsim cov ntaub ntawv ua, mining, thiab lwm yam teb. Raws li ib feem tseem ceeb ntawm cov xuab zeb ntau lawm kab, nws transforms crushed raw khoom rau hauv cov xuab zeb tiav. Nws kev khiav hauj lwm efficiency thiab cov zis ncaj qha txiav txim siab tag nrho cov peev xwm thiab cov khoom zoo ntawm tag nrho cov kab ntau lawm.
Tawm tsam qhov kev xav tau nce ntxiv rau cov xuab zeb thiab pob zeb sib sau ua ke, cov xuab zeb ua tshuab - ua cov khoom siv tseem ceeb hauv kev sib tsoo thiab cov xuab zeb ntau lawm kab - muaj cov khoom lag luam uas cuam tshuam ncaj qha rau ob txoj haujlwm muaj peev xwm thiab kev lag luam rov qab los. Hauv kev ua haujlwm, ntau lub tuam txhab feem ntau ntsib teeb meem ntawm cov xuab zeb ua tshuab ua tsis tau raws li qhov xav tau ntau lawm. Qhov no tsis tsuas yog cuam tshuam cov sijhawm tsim khoom tab sis kuj tseem ua rau cov nqi ua haujlwm nce ntxiv, ua qhov mob tseem ceeb uas txwv kev lag luam txoj kev loj hlob zoo.
Cov zis qis hauv cov xuab zeb ua tshuab tsis yog tshwm sim los ntawm ib qho tseem ceeb, tab sis muaj feem xyuam nrog ntau yam xws li cov cuab yeej siv tau zoo, cov yam ntxwv ntawm cov khoom siv raw, cov qauv kev ua haujlwm, thiab kev saib xyuas. Kev nthuav qhia cov ntsiab lus cuam tshuam tseem ceeb no yog qhov tseem ceeb tshaj plaws rau cov tuam txhab lag luam txhawm rau txhim kho kev tsim khoom raws li lub hom phiaj thiab ua kom muaj peev xwm tag nrho.
Khoom hardness, viscosity, noo noo cov ntsiab lus, thiab lwm yam khoom ncaj qha cuam tshuam rau cov xuab zeb ua efficiency. Xaiv cov qauv khoom tsim nyog thiab kev ua haujlwm tsis tu ncua yog qhov tseem ceeb rau kev ua haujlwm ntawm cov xuab zeb ua tshuab. Lub tshuab kev tshaj lij, hnav-tiv taus ua ke nrog kev ua haujlwm ntawm kev tshawb fawb ua rau nws yooj yim kom ua tiav cov khoom tsim tau zoo thiab txuag hluav taws xob.
1. Khoom siv Hardness
Cov ntaub ntawv hardness yog ib qho tseem ceeb ntawm cov khoom tsim tawm ntawm cov xuab zeb ua tshuab. Xaiv cov qauv khoom tsim nyog thiab ua haujlwm tsis tu ncua yog qhov tseem ceeb rau kev ua kom lub tshuab muaj peev xwm ntau lawm ob npaug. Lub tshuab kev tshaj lij, hnav-tiv taus ua ke nrog kev ua haujlwm ntawm kev tshawb fawb ua kom muaj txiaj ntsig zoo thiab txuag hluav taws xob.
2. Khoom siv viscosity
Cov ntaub ntawv uas muaj viscosity siab yuav ua raws li cov phab ntsa sab hauv ntawm cov xuab zeb ua tshuab thaum ua. Yog tias tsis tau ntxuav kom raws sijhawm, qhov kev tsim kho no tuaj yeem txo cov zis thiab ua haujlwm tau zoo. Rau cov khoom siv viscosity siab, kev tu lub tshuab sab hauv yog ib txwm tsim nyog los tswj kev ua haujlwm zoo.
3. Cov ntaub ntawv noo noo
Cov dej noo ntau dhau nyob rau hauv cov khoom noj tuaj yeem ua rau cov zis qis. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau xyuas cov qib noo noo ua ntej ua haujlwm thiab khaws cia rau hauv qhov tsim nyog kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov xuab zeb ua tshuab.
4. Zoo thiab qauv ntawm cov xuab zeb ua tshuab
Ntau hom xuab zeb ua tshuab sib txawv hauv kev tsim muaj peev xwm, kev siv hluav taws xob, kev ua haujlwm zoo, plua plav tsim, thiab lwm yam ntxwv. Xaiv tus qauv zoo yog qhov tseem ceeb. Cov tshuab ua haujlwm siab tsis yog tsuas yog siv zog ntau dua thiab zoo ib puag ncig, tab sis kuj yooj yim ua tiav cov txiaj ntsig xav tau. Tsis tas li ntawd, cov khoom tsim los ntawm cov kws tshaj lij kev lag luam feem ntau txhim khu kev qha, hnav-tiv taus, thiab kav ntev.
5. Kev khiav hauj lwm thiab kev saib xyuas ntawm cov xuab zeb ua tshuab
Kev ua haujlwm thiab kev saib xyuas ntawm lub tshuab ua xuab zeb kuj cuam tshuam rau nws cov zis. Kev saib xyuas tsis tu ncua-xws li lubrication, tu, thiab tshuaj xyuas cov khoom siv- tuaj yeem ua kom cov khoom tsim tau zoo thiab ua kom lub tshuab ua haujlwm ntev.
Qhov teeb meem ntawm cov khoom siv qis hauv cov xuab zeb ua tshuab yog qhov tseem ceeb ntawm kev xav txog qhov tsis sib xws ntawm ntau qhov sib cuam tshuam, nrog rau kev ua haujlwm ntawm cov khoom siv, cov yam ntxwv ntawm cov khoom siv raw, kev ua haujlwm, thiab cov txheej txheem tu. Rau cov lag luam, txheeb xyuas qhov tseem ceeb ntawm cov khoom lag luam poob qis -txawm tias nws yog los ntawm cov khoom siv tsis sib haum thiab cov khoom siv raw, cov txheej txheem kev ua haujlwm tsis zoo, lossis kev saib xyuas tsis txaus- yog qhov tseem ceeb rau kev kov yeej cov khoom ntim khoom.
Los ntawm kev siv cov cuab yeej siv tshawb fawb, kev ua kom zoo ntawm cov khoom siv raw khoom ua ntej, kev ua haujlwm ntawm kev ua haujlwm, thiab tsim kom muaj kev saib xyuas tsis tu ncua, cov tuam txhab tuaj yeem tsis tsuas yog ua kom cov khoom tsim tawm ntawm lawv cov xuab zeb ua tshuab, tab sis kuj txuas ntxiv cov cuab yeej siv lub neej thiab txo cov nqi ua haujlwm tag nrho.
