NFPA 704 tag yog xav tau thaum lwm Tsoom Fwv Teb Chaws, lub xeev los yog lub zos txoj cai los yog cai xav tau lawv siv. NFPA 704 tsis qhia meej tias thaum twg lub thawv, lub tank lossis qhov chaw yuav tsum tau sau nrog 704 pob zeb diamond.
Ntawm no, puas yog NFPA pob zeb diamond tseem siv?
Lub Tebchaws Hluav taws Koom haum tiv thaiv ( NFPA ) tsim a phom sij ID nkag mus rau cov neeg muaj xwm txheej ceev uas yog tseem siv tau hnub no. Yav dhau los qee cov tuam txhab tshuaj siv NFPA pob zeb diamond ntawm lawv cov khoom, tab sis tam sim no cov ntawv yuav tsum tau siv GHS labeling. Dawb teb yog siv los nthuav qhia cov xwm txheej tshwj xeeb.
Ib yam li ntawd, cov lej txhais li cas ntawm NFPA pob zeb diamond? Lub Tebchaws Hluav taws Koom haum ( NFPA ) tau tsim muaj xim-coded tus lej lub npe hu ua TIAB SA 704 . Lub kaw lus siv cov xim-coded pob zeb diamond nrog plaub quadrants nyob rau hauv uas tus lej yog siv nyob rau hauv lub sab sauv peb quadrants los qhia qhov degree ntawm kev noj qab haus huv phom sij (xiav), flammability phom sij (liab), thiab reactivity phom sij (daj).
Kuj paub yog, koj nyeem NFPA pob zeb diamond li cas?
Yuav Ua Li Cas Nyeem NFPA Pob Zeb Diamond
- Red Section: Flammability. Cov xim liab-xim ntawm NFPA Pob Zeb Diamond nyob rau sab saum toj lossis kaum ob teev ntawm txoj haujlwm ntawm lub cim thiab qhia txog cov khoom siv hluav taws xob thiab ua rau muaj hluav taws kub thaum raug tshav kub.
- Yellow Section: Instability.
- Blue Section: Health Hazards.
- Dawb Ntug: Kev ceev faj tshwj xeeb.
Dab tsi yog NFPA ntsuam xyuas rau cov nplaim taws?
Cov tshuaj chemical yog ntsuas rau degree ntawm HNUB NYOOG RISK (xiav pob zeb diamond ), FLAMMABILITY (liab pob zeb diamond ), REACTIVITY (daj pob zeb diamond ), ntawm qhov ntsuas ntawm 0 txog 4. Cov dawb pob zeb diamond yog siv los qhia txog qhov muaj ntau ntawm cov tshuaj uas muaj cov dej tsis zoo reactivity (W) lossis muaj peev xwm oxidative (oxy).

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Puas yog pob zeb av nplaum yog pob zeb sedimentary?
Boulder Clay. Boulder av nplaum los ntawm Yorkshire, UK los ntawm lub sij hawm Pleistocene, qhia random loj ntau yam clasts nyob rau hauv ib tug glacial av nplaum matrix. Tsim los ntawm ntau yam txheej txheem glacial lossis dej khov, cov pob zeb sedimentary no muaj ntau qhov ntau thiab tsawg
Puas yog hlau yog pob zeb lossis pob zeb?
Los yog, cov ntxhia los yog ib qho sib xyaw ntawm cov ntxhia los ntawm cov khoom tseem ceeb, tshwj xeeb tshaj yog cov hlau, tuaj yeem tau txais txiaj ntsig zoo los yog rho tawm yog cov ore. Hlau - Ib qho hlau ntawm ob lossis ntau dua hlau. Yog li ntawd, pob zeb muaj cov zaub mov, uas nyob rau hauv loj concentration yog hu ua ores thiab cov no yog mined rau hlau
