Dab tsi ntawm pob zeb yog basalt?
Basalt yog ib lub pob zeb uas tsis muaj zog
Basalt yog ib lub pob zeb uas tsis tshua muaj tshwm sim uas yog hom pob zeb tsis zoo. Igneous pob zeb yog pob zeb tsim los ntawm qhov txias thiab solidification ntawm molten magma ntawm qhov kub thiab txias. Basalt yog dav siv nyob rau hauv kev tsim kho, kev, thiab vaj vim nws cov khoom tshwj xeeb, xws li siab hardness, nplua nplej, thiab compact qauv.
Properties thiab muaj pes tsawg leeg ntawm basalt
Basalt muaj lub cev zoo heev nrog cov ntxhia pob zeb zoo thiab zoo crystallization, uas ua rau cov tawv nqaij tawv thiab zoo ib yam. Lub pob zeb no yog ib qho nyuaj, hnav-tiv taus, acid thiab alkali-resistant, thiab muaj kev hloov tau zoo rau txhua yam kev hnyav. Nyob rau tib lub sijhawm, lub Tshuaj Kev sib xyaw ntawm basalt yog dominated los ntawm silicates thiab muaj ntau yam ntxhia cov ntsiab lus, muab nws lub siab ceev thiab zoo heev compressive zog.
Kev siv thaj chaw ntawm basalt
Hauv thaj teb ntawm Kev tsim kho, basalt feem ntau yog siv rau sab hauv tsev thiab sab nraum zoov kho kom zoo nkauj, xws li flooring thiab phab ntsa. Nws ruaj khov xim thiab zoo heev durability uabasalt pob zeb qhia tshwj xeeb kev zoo nkauj hauv kev tsim kho. Hauv kev tsim kho txoj kev, basalt kuj tau siv dav hauv curbs, pavement paving, thiab lwm yam, nws cov yam ntxwv nyuaj thiab ruaj khov tuaj yeem tiv taus cov tsheb sib tsoo. Tsis tas li ntawd, hauv kev tsim toj roob hauv pes, basalt kuj tseem siv los ua pob zeb, duab puab, thiab lwm yam chaw ua haujlwm toj roob hauv pes.
Basalt mining thiab ua
Basalt feem ntau yog mined nyob rau hauv qhov qhib qhov twg geological tej yam kev mob yog haum. Thaum lub sij hawm ua, basalt yog ua rau ntau qhov ntau thiab tsawg ntawm lub tsev pob zeb los ntawm sawing, sib tsoo, polishing, thiab lwm yam txheej txheem. Vim nws cov hardness nruab nrab thiab kev ua haujlwm yooj yim, nws ua rau basalt mining thiab kev ua haujlwm kuj yooj yim thiab tus nqi qis.
Basalt yog ib lub pob zeb uas tsis muaj zog nrog lub siab hardness, abrasion tsis kam, acid, thiab alkali tsis kam, thiab lwm yam. Nws yog dav siv hauv kev tsim kho, txoj kev, lub vaj, thiab lwm yam. Nws cov khoom tshwj xeeb thiab ntau yam kev siv ua basalt yog ib lub pob zeb tseem ceeb.
