Homogeneity Test thiab Stability

Qhov kev ntsuam xyuas homogeneity tau ua tiav ntawm lub raj mis los ntawm kev txiav txim siab ntawm tshauv thiab sulfur.Qhov tsawg kawg nkaus qhov hnyav ntawm cov qauv coj los soj ntsuam yog 1.0g (ash) lossis 0.05g (sulfur).Kev txheeb xyuas qhov sib txawv tau pom tias qhov sib txawv ntawm cov fwj sib txawv tsis txawv qhov txawv ntawm qhov sib txawv ntawm kev txiav txim siab rov ua dua.

Lub validation ntawm cov ntawv pov thawj muaj nuj nqis yog ib xyoos.Daim ntawv pov thawj yuav ua rau txhua xyoo ib zaug kho cov ntawv pov thawj muaj txiaj ntsig tuaj yeem muab rau ntawm daim ntawv thov los ntawm Shandong Institute of Metallurgical Science Co., Ltd.

Yam ntxwv Ntawm Txoj Kev

Kev ua yam ntxwv ntawm txoj kev siv ob lossis ntau txoj hauv kev ntawm kev ua kom pom tseeb hauv 9 lub chaw soj ntsuam muaj peev xwm.

Yam khoom	Txoj kev tsom xam
Tag nrho cov sulfur	GB/T 214-2007 Kev txiav txim siab ntawm tag nrho cov sulfur hauv thee, Eschka txoj kev
Tshauv thiab Volatile teeb meem	GB/T 212-2008 Proximate tsom xam ntawm thee
Tus nqi calorific tag nrho	GB/T 213-2008 Kev txiav txim siab ntawm calorific nqi ntawm cov thee
Carbon thiab Hydrogen	GB/T 476-2008 Kev txiav txim siab ntawm carbon thiab hydrogen hauv thee
Nitrogen	GB/T 19927-2008 Kev txiav txim siab ntawm nitrogen hauv thee
Muaj tseeb txheeb ze ntom ntom	GB/T 217-2008 Kev txiav txim siab qhov tseeb txheeb ze ntawm cov thee

Kev Ua Haujlwm Ntawm Cov Khoom Muaj Nqis Thiab Tsis Txaus Siab

Cov ntawv pov thawj kev soj ntsuam tau ua los ntawm Suav National Standard (GB) txoj hauv kev los ntawm ntau lub chaw soj nstuam tsim nyog.

Tus nqi ntawv pov thawj tau hais tias X_T±U, qhov twg X_Tyog tus nqi nruab nrab thiab U yog qhov nthuav dav tsis paub tseeb (95% qib kev ntseeg siab).Qhov tsis paub tseeb uas tau muab rau hauv cov lus 1 suav nrog kev tso cai rau tus qauv degradation hauv ib xyoos.

Kev txheeb xyuas kev txheeb xyuas thiab tag nrho cov kev taw qhia thiab kev sib koom tes ntawm cov kev ntsuas kev ua rau muaj ntawv pov thawj tau ua los ntawm Shandong Institute of Metallurgical Science Co., Ltd.

Metrological Traceability

Ua ntej tus yam ntxwv ntawm 9 lub chaw soj nstuam tsim nyog, cov cuab yeej thiab cov cuab yeej siv yuav tsum raug txheeb xyuas lossis ntsuas, thiab cov ntaub ntawv pov thawj yuav tsum tau siv rau kev saib xyuas thaum lub sijhawm ua tus cwj pwm kom paub meej cov ntaub ntawv siv tau.

Ntim, Cia thiab siv

1) Cov ntaub ntawv pov thawj no tau ntim rau hauv lub raj mis xim av.Txhua qhov hnyav 50 g.

2) Lub raj mis uas muaj cov ntaub ntawv yuav tsum tau ceev nrooj nres thiab khaws cia rau hauv qhov chaw txias thiab qhuav, thiab qhib tsuas yog thaum tsim nyog.

3) Tag nrho cov ntaub ntawv tau nthuav tawm ntawm cov hauv paus qhuav.Cov dej noo (nqus dej hauv cov qauv ntsuas kev ntsuas dav dav) siv rau kev suav cov ntaub ntawv ntawm cov hauv paus qhuav yog txiav txim siab raws li kev ntsuas dej noo hauv GB / T 212-2008 "Proximate Analysis of Coal".

4) Cov txiaj ntsig tau muab rau hauv cov lus 1 ntawm daim ntawv pov thawj no yog cov txiav txim siab thaum Lub Xya Hli-01-2021 rau CRM.
