Laboratory Cement Blaine Specific Surface Area Tester
Ib, Specification
Raws li GB / T8074-2008 lub xeev tus qauv peb tsim tus qauv tshiab SZB-9 Auto Ratio nto tester.Lub tshuab yog tswj los ntawm lub khoos phis tawj, thiab ua haujlwm los ntawm cov mos txwv kov, nws pib tswj tag nrho cov txheej txheem xeem.Nws pib nco txog cov coefficient, tso saib qhov piv ntawm thaj chaw tus nqi ncaj qha tom qab kev sim ua tiav, nws kuj tuaj yeem pib nco lub sijhawm sim.
2.
BET (Brunauer, Emmett thiab Teller) txoj kev xav feem ntau yog siv los ntsuas cov ntaub ntawv roj adsorption thiab tsim kom muaj qhov tshwj xeeb ntawm thaj chaw tshwm sim qhia nyob rau hauv cov cheeb tsam ntawm ib pawg ntawm cov qauv (m2 / g).Cov txheej txheem yog siv los ntawm ntau lub koom haum xws li ISO, USP thiab ASTM.
Txoj kev no yog siv dav rau cov ntaub ntawv feem ntau, tab sis feem ntau txhim khu kev qha rau cov ntaub ntawv nrog hom II lossis Hom IV isotherm nrog rau theem txaus ntawm kev sib cuam tshuam ntawm cov pa adsorbate thiab qhov chaw.Rau cov ntaub ntawv nrog lwm hom isotherms, BET txoj kev xav yuav tsis siv rau ntau yam laj thawj thiab yog li yuav tsum tau ceev faj.
Ua ntej kev soj ntsuam, cov qauv yuav tsum tau ua ntej kom tshem tawm lub cev sib txuas cov impurities los ntawm qhov chaw ntawm cov hmoov hauv cov txheej txheem hu ua degassing lossis outgassing.Qhov no feem ntau ua tiav los ntawm kev siv qhov ntsuas kub rau cov qauv ua ke nrog lub tshuab nqus tsev lossis tsis tu ncua ntws inert roj.Cov txheej txheem no yuav tsum tau ua tib zoo tswj thiab saib xyuas kom thiaj li tsim tau qhov tseeb tshaj plaws thiab rov ua tau

三:Operate board description
uDisplay cheeb tsam
Yog LCD npo, tso saib cheeb tsam.
v Chaw ua haujlwm
Tsim los nrog 8 tus yuam sij, suav nrog 【Sab laug】 【Right】 【Up】 【Down】 【Reset】 【S nqi】 【K nqi】 【Enter】
四: Instrument element
u Qhov sib piv cheeb tsam qhia tag nrho cheeb tsam ntawm pob zeb ua hmoov.
v Cov txheej txheem yog nyob ntawm cov huab cua uas tsis muaj zog los ntawm kev ua haujlwm tsis tu ncua thiab cov tuab tuab tuab, qhov sib txawv kuj tuaj yeem ua rau sib txawv khiav ceev, thiab siv cov ntsiab lus no los ntsuas qhov sib piv ntawm thaj chaw.
w Raws li tus qauv GB / T807-2008 commendatory xam cov mis
S - Qhov ratio ntawm cov qauv xeem, SS - Qhov ratio ntawm cov qauv hmoov, cm2 / g
T-Cov kua txwv lub sij hawm ntawm cov qauv kuaj, TS — tus qauv hmoov kua downtime, vib nas this.
η-Cov huab cua mucosity thaum kuaj cov qauv hauv qhov kub thiab txias, μPa∙s
ηs-Cov huab cua mucosity thaum tus qauv hmoov nyob rau hauv instant kub, μPa∙s
ρ—Density of test sample, ρs—Density of standard test sample, g/cm3
ε-Interspace tus nqi ntawm cov qauv xeem, εs-Interface tus nqi ntawm tus qauv xeem qauv
Nyob rau hauv saum toj no xam cov mis, vim hais tias tus qauv hmoovεs yog tsau, thiab yog 0.5, yog li siv tus nqi kom raug.
五 , : Test and demarcation
1) .Siv cov roj hmab gag foob lub thoob ntug ces kuaj, teem qhov tsim nyog parameter ces pib ntsuas.Thaum ntsuas pib nres, xyuas lub ntsej muag ua kua yog poob qis, thiab cov xwm txheej zoo li qub tsis poob.
2) Qauv txheej ntim kuaj
六 、 Test process
1) Qauv npaj
2) Paub meej cov qauv kom muaj nuj nqis
3) Qauv txheej ua
