Yuav Ua Li Cas Paub Qhov Tseeb Thiab Tsis Zoo Quartz Pob Zeb
Jul 30, 2021
Nws yog ib qho tseem ceeb heev los txiav txim qhov zoo ntawm quartz pob zeb yog qhov ua tiav, vim tias qhov ua tiav sawv cev rau qhov tsis kam tiv taus. Txoj hauv kev yooj yim tshaj plaws yog siv tus cim kos rau ntawm lub pob zeb quartz thiab saib seb nws puas tuaj yeem tshem tawm. Yog tias nws tuaj yeem tshem tawm, nws txhais tau tias nws muaj qhov ua kom tsis muaj zog tiv taus. Yog tias nws tsis tuaj yeem tshem tawm nws txhais tau tias nws muaj qhov tsis zoo tiv taus. Nws raug nquahu kom tsis txhob yuav nws. Ib qho ntxiv, cov pob zeb quartz uas tsim los ntawm cov tuam txhab tsim khoom niaj hnub muaj cov lej cim-dav hlau nyob tom qab, thiab xyuam xim rau cov paib.
Txoj kev tshwj xeeb:
1. Hardness yog qhov qhia txog kev hnav tsis kam. Txoj hauv kev yooj yim yog siv rab riam hlau los kos, thiab tus yuam sij tsis tuaj yeem siv rau kev txheeb xyuas. Quartz pob zeb yog ua los ntawm 94% quartz thiab 6% cob, nrog qhov tawv ntawm 7 degrees, thaum granite yog sib xyaw los ntawm cov hmoov zeb thiab cov pob zeb, yog li qhov nyuaj feem ntau yog 4-6 degrees. Yooj yim muab, piv ntawm cov pob zeb quartz Cov granite yog qhov nyuaj, tiv taus ntau dua rau khawb thiab puas.
2. Cov hlau riam hlais hla, ua ib lub cim dawb ntawm lub pob zeb quartz dag. Vim tias lub phaj tsis nyuaj li hlau, cov nplaim txiav los ntawm cov riam hlau, qhia pom dawb hauv. Thaum lub pob zeb quartz dawb huv tau khawb los ntawm rab riam hlau, nws tsuas yog ua cim xim dub, uas yog los ntawm cov riam hlau tsis tuaj yeem khawb lub pob zeb quartz, tab sis tawm ntawm cov hlau, ib qho dub thiab ib qho dawb, qhov tseeb thiab qhov tsis tseeb tshwm sim. 3. Vim yog cov yam ntxwv ntawm nws tus kheej cov khoom, pob zeb quartz txiav txim siab nws qhov kub tsis kam. Qhov kub qis dua 300 degrees Celsius yuav tsis muaj kev cuam tshuam rau nws, uas yog, nws yuav tsis deform thiab tawg; vim tias muaj cov tshuaj loj loj, cov pob zeb quartz muaj cov kua ntau heev. Yog li ntawd, nws tshwj xeeb tshaj yog ua rau deformation thiab hlawv ntawm qhov kub siab.
4. Nias lub taub hau luam yeeb ntawm lub txee, lossis hlawv ncaj qha nrog lub teeb. Yog tias tsis muaj kab, nws yog cov khoom lag luam tiag tiag, thiab ib qho nrog cov xim dub hlawv yog qhov cuav.
