Rau kuaj lub hardness ntawm ib qho piv txwv coj nws thiab sim kos nws nrog thawj pob zeb hauv koj tawv kev, Talc. Yog hais tias nws yog scratched ces lub pob zeb koj yog kuaj yog tawv 1. Yog tias tsis yog, sim kos cov Talc nrog koj pob zeb . Yog tias pob zeb khawb cov Talc ces nws nyuaj tshaj cov Talc.
Tsis tas li ntawd, koj ua li cas kuaj qhov hardness ntawm cov ntxhia?
Hardness yog ntsuas los ntawm kev tiv thaiv uas ib tug du nto muab rau abrasion. Qhov degree ntawm tawv yog txiav txim los ntawm kev soj ntsuam qhov sib piv yooj yim los yog nyuaj uas ib tug twg ntxhia yog khawb los ntawm lwm tus. Lub rooj qhia Mohs tus txheeb ze tawv nplai. Mohs' original tawv qhov tseem ceeb yog highlighted nyob rau hauv daj.
Tom qab ntawd, lo lus nug yog, koj ua li cas kuaj lub pob zeb rau cov zaub mov? Ua raws li qhov yooj yim no, ib kauj ruam ntawm kev ua:
- Hardness test - Kos lub pob zeb nrog ib tug ntiv tes, ib tug tooj liab penny, iav phaj los yog ntsia thawv, thiab ib tug ceramic phaj.
- Xim streak test - Kev sim rau "xim streak" ntawm cov pob zeb los ntawm rub lub pob zeb hla cov phaj ceramic hauv cov khoom siv Mineral Test, los yog hla tus.
Raws li, koj yuav ua li cas kuaj lub hardness ntawm pob zeb diamond?
Rau ntsuas tus tawv ntawm a pob zeb diamond , lossis ib qho ntxhia, peb siv lub nplai hu ua Mohs Scale, npe tom qab nws tus neeg tsim khoom. Txoj kev no suav nrog kuaj kev khawb ntawm ib qho ntxhia los ntawm kev pom yog tias lwm cov ntxhia muaj peev xwm tsim tau khawb.
Dab tsi mineral muaj ib tug hardness ntawm 7?
quartz

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
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
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Dab tsi yog hardness Yuav ua li cas txiav txim siab hardness ntawm dej?
Hardness ntawm dej yog txiav txim los ntawm titrating nrog ib tug txheej txheem tov ntawm ethylene diamine tetra acetic acid (EDTA) uas yog ib tug complexing neeg sawv cev. Txij li EDTA yog insoluble nyob rau hauv dej, disodium ntsev ntawm EDTA yog siv rau qhov kev sim no. EDTA tuaj yeem tsim plaub lossis rau rau kev sib koom tes nrog cov hlau ion
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
