Dab tsi yog qhov muaj pes tsawg leeg ntawm cov pob zeb quartz pob zeb
Jun 04, 2021
Lub pob zeb quartz pob zeb yog tsim los ntawm kev hloov kho cov pob zeb thiab cov pob zeb tawg, uas yog nruab nrab lossis me ntsis alkaline. Pob zeb dag muaj cov qauv ntom, yog li qhov hws me me, thiab qhov tshwm sim ntawm nws cov tsos mob yog me me. Raws li kev tiv thaiv kev txhawj xeeb, nws feem ntau yog cov tshuaj tua kab mob. Qhov zoo dua yog xim tuaj yeem hloov kho, uas yog qhov zoo rau kev kho kom zoo nkauj ntawm qhov chaw. Qhov tsis zoo yog qhov tawv tsis txaus thiab lub teeb ci tsis sib xws.
Lub hauv paus tseem ceeb ntawm cov pob zeb quartz yog quartz. Quartz yog cov ntxhia uas tuaj yeem yooj yim ua kua thaum ua kom sov lossis nyob hauv siab. Nws kuj tseem yog cov pob zeb tsim ua cov ntxhia ntau heev, uas pom muaj nyob hauv peb hom pob zeb loj. Vim tias nws crystallizes lig hauv cov pob zeb tawg, nws feem ntau tsis muaj lub ntsej muag ua tiav thiab feem ntau tau ntim nrog lwm cov pob zeb tsim cov zaub mov uas ua rau ua ntej. Cov muaj pes tsawg leeg ntawm quartz yog yooj yim silicon dioxide (sio2), iav ci, tsis muaj qhov tawg, tab sis lub plhaub zoo li pob txha tawg. Microcrystalline quartz hu ua chalcedony, agate lossis jasper. Ntshiab quartz tsis muaj xim, tab sis nws qhia xim sib txawv vim nws feem ntau muaj qhov tsis zoo ntawm kev hloov pauv.
Quartz ruaj khov heev, tsis yooj yim rau huab cua lossis hloov mus rau lwm hom pob zeb hauv av. Silicon nyob hauv pab pawg plaub ntawm cov lus teev tseg. Nws tau nthuav dav dav hauv lub ntiaj teb' cov tawv ntoo. Nws nyob hauv qhov chaw thib ob hauv qhov kev txiav txim ntawm kev faib khoom ntau ntawm txhua lub ntsiab lus, thib ob tsuas yog oxygen. Silicon kuj tseem yog cov khoom siv oxygen-philic, uas feem ntau yog ua ke nrog cov pa txhawm rau tsim cov silicon-oxygen tetrahedron. SiO4 sib tov 4 los tsim cov tshuaj silicate sib txawv los ntawm kev sib xyaw silicon oxygen tetrahedrons hauv ntau yam. Silicates suav rau ntau dua 80% ntawm cov pob zeb hauv av, thiab silicon tseem tau muab faib ua cov dawb silicon oxygen-SiO2. Nws tuav txoj haujlwm tseem ceeb thiab muaj kev ruaj ntseg zoo heev. Nws yog ib qho thiab tseem ceeb ntawm cov pob zeb tsim cov ntxhia hauv qhov. Nws kuj yog ib yam ntawm cov pob zeb uas muaj coob thiab ntau yam hauv kev lag luam hniav nyiaj hniav kub. Lub pov haum nrog SiO2 ua lub hauv paus tseem ceeb muaj ntau yam ntxwv. txawv.
