Ntoo grain pob zeb yog ib hom limestone
Ntoo pob zeb yog dab tsi?
Cov khoom tseem ceeb yog calcium carbonate
Ntoo pob zeb
Yog ib lub pob zeb muaj nuj nqis
Nws yog ib hom pob zeb tsim los ntawm rov los nag los ntawm calcium carbonate
Vim muaj kev hloov pauv ntawm ntau yam xwm txheej thaum lub caij los nag
Tsim cov ntoo zoo li kev ntxhib los mos.
Muaj ntau hom marble nrog ntoo grain thiab xim sib txawv. Vim hais tias ntawm cov txheej txheem sib txawv thiab kev txiav, qhov ntev txiav yog ntoo grain, thiab kab rov tav txiav tuaj yeem pom moiré, dej nplej lossis kev ntxhib los mos zoo ib yam li cov nplhaib txhua xyoo.
Nws tuaj yeem siv tau ua hauv pem teb, pob zeb kab, veneer vaj huam sib luag, kab tiab, stair kauj ruam thiab pob zeb tshwj xeeb. Nws yog hom A pob zeb tsis tshua muaj.
PART01: Ntoo grain pob zeb faib
Raws li ntau hom pob zeb, nws tuaj yeem muab faib ua marble ntoo pob zeb thiab sandstone ntoo pob zeb (ib feem me me yog granite ntoo pob zeb);
Raws li cov xim sib txawv, nws tuaj yeem muab faib ua xim ntoo pob zeb, pob zeb liab thiab pob zeb daj;
Raws li cov ntoo sib txawv, nws tau muab faib ua cov ntoo zoo, cov ntoo loj, cov ntoo ncaj, cov ntoo ntoo, thiab lwm yam .;
Raws li lub npe ntawm lub hauv paus chiv keeb, cov pob zeb ntoo-grain tuaj yeem muab faib ua Guizhou ntoo-grain pob zeb, Fabkis ntoo-grain pob zeb, Italian ntoo-grain pob zeb thiab lwm yam.
Ntoo grain pob zeb feem ntau belongs rau ib hom ntawm marble, thaum sandstone ntoo grain pob zeb belongs rau sandstone. Ntoo grain yog tsim nyob rau hauv Cambrian strata thiab belongs rau marine deposits thiab yog hlau-nplua nuj argillaceous dolomite.
Nov yog qee yam ntoo-grain pob zeb:
PART02: Ntoo pob zeb tu
Cov lus nug nquag nug txog Wood Stone
Nyob rau hauv ib tug loj tus naj npawb ntawm daim ntawv thov txhua hnub, nws pom tau hais tias ntoo grain pob zeb yog feem ntau ua rau cov nram qab no teeb meem loj dua lwm hom ntawm ntuj pob zeb:
* Tsis yooj yim rau polish.
* Yooj yim hloov xim. Tom qab siv cov pob zeb ntoo, cov xim yuav hloov ntawm lub teeb mus rau qhov tsaus ntuj, los ntawm tsaus rau daj thiab lwm yam tshwm sim zoo sib xws.
* Cov pob qij txha ntawm cov pob zeb ntoo yog qhov ua rau muaj kuab lom thiab tsis muaj xim.
* Yooj yim rov qab mus rau alkali.
* Yooj yim polluted.
Cov yam ntxwv ntawm ntoo pob zeb
①Limestone Ntoo grain pob zeb yog ib hom limestone uas nws lub ntsiab yog calcium carbonate (CaCO3).
②Powder qauv Txawm hais tias nws muaj cov ntaub ntawv zoo sib xws thiab cov qauv nrog marble, muaj qhov sib txawv ntawm cov ntoo-grain pob zeb thiab marble. Ib qho ntawm cov yam ntxwv tseem ceeb yog tias cov txheej txheem tsim ntawm limestone tsis tau dhau los ua qhov tsis zoo thiab crystallization ntawm marble.
Qhov no ua rau limestone nthuav tawm cov hmoov zoo hauv cov qauv. Nws zoo li ntom, tab sis qhov tseeb nws yog qhov sib txawv ntawm cov qauv siv lead ua hauv marble thiab granite.
③ Lub cev muaj zog Limestone yog qhov tsis yooj yim, thiab nws cov flexural bulk ceev, curvature thiab compressive zog tsis siab.
④ Kev nqus dej siab Cov calcium carbonate muaj pes tsawg leeg thiab cov qauv hmoov ua rau cov dej nqus ntawm limestone feem ntau siab. Peb txhua tus tau muaj kev paub zoo sib xws ntawm cov pob zeb uas tsis muaj kev tiv thaiv ntoo-grain:
Ib txhia dej, nchuav rau ntawm ntoo-grain pob zeb, zoo li tau nqus los ntawm daim txhuam cev, thiab sai sai nkag mus rau hauv pob zeb. Qhov no feature yog pom tseeb txawv los ntawm cov tshuaj tiv thaiv ntawm sprinkling ntawm marble, granite thiab lwm yam pob zeb.
