Hom Pob Zeb

Ntuj pob zeb hais txog cov ntsiab lus dav dav ntawm cov ntaub ntawv muab rho tawm los ntawm cov pob zeb ntuj thiab ua tiav rau hauv cov khoom thaiv los yog phaj. Ob hom pob zeb feem ntau siv hauv kev lag luam kho kom zoo nkauj hauv tsev yog pob zeb ntuj thiab pob zeb dag. Cov pob zeb ntuj xws li marble, granite, limestone, thiab lwm yam. Lub pob zeb ntuj siv rau kev kho kom zoo nkauj hauv tsev feem ntau suav nrog granite thiab marble. Ntuj pob zeb yog ib qho ntawm cov khoom siv engineering qub tshaj plaws. Ntuj pob zeb muaj zog compressive siab, zoo hnav tsis kam thiab durability, zoo nkauj thiab zoo nkauj nto tom qab ua tiav, kev faib khoom thoob plaws, nplua nuj reserves, yooj yim hauv zos cov ntaub ntawv, cov nqi qis thiab lwm yam zoo. Nws yog cov khoom siv tseem ceeb rau kev tsim cov phab ntsa hauv nroog, txuas hniav, tsev, txoj kev thiab kev txuag dej hauv kev tsim vaj tsev qub qub thiab niaj hnub nim no. Nws yog ib qho ntawm cov khoom siv kho kom zoo nkauj ntawm niaj hnub engineering engineering.
Ntuj pob zeb tuaj yeem muab faib ua peb pawg. Igneous pob zeb yog tsim los ntawm melting los yog ib nrab melting ntawm pob zeb nyob rau hauv lub mantle los yog crust, xws li cua txias thiab consolidation ntawm magma. Granite yog ib hom igneous pob zeb; Sedimentary pob zeb yog pob zeb thiab sandstones tsim los ntawm huab cua cov khoom ntawm lwm cov pob zeb thiab ib co volcanic eruptions nyob rau hauv qhov chaw tsis tob heev nyob rau hauv lub ntiaj teb no nto los ntawm kev thauj mus los, deposition thiab diagenesis ntawm dej ntws los yog glaciers; Metamorphic pob zeb yog lwm hom pob zeb ib txwm metamorphosed los ntawm ib lub pob zeb nyob rau hauv kev sib xyaw ua haujlwm ntawm qhov kub thiab txias thiab cov ntxhia. Marble, slate, quartzite thiab jade yog tag nrho cov pob zeb metamorphic.
Granite yog ib qho nyuaj heev pob zeb nrog siab ntom ntom, kos tiv taus thiab corrosion tsis kam. Nws yog qhov tsim nyog rau cov plag tsev thiab chav ua noj countertops. Muaj ntau pua hom ntawm granite.
Marble hais txog sedimentary lossis metamorphic carbonate pob zeb, suav nrog marble, dolomite, limestone, sandstone, shale thiab slate, uas yog cov khoom ntawm limestone. Marble yog lub pob zeb metamorphic uas tuaj yeem polished. Marble yog mos thiab yooj yim rau khawb los yog corroded los ntawm acids. Muaj ntau ntau yam ntawm marble thoob plaws lub ntiaj teb no, thiab cov tshiab ntoo-grained jade blanks raug pom zoo.
Limestone yog ib hom pob zeb sedimentary, uas yog tsim los ntawm calcite thiab sediment thiab tsim ntau yam xim.
Sandstone kuj yog ib hom pob zeb sedimentary, uas yog tsim los ntawm xoob quartz xuab zeb hais nrog ntxhib kev ntxhib los mos. Muaj ntau hom sandstone xaiv los ntawm.
Slate yog ib hom metamorphic pob zeb. Cov pob zeb qub yog argillaceous, silty lossis nruab nrab tuff, uas tuaj yeem tev rau hauv nyias nyias raws cov kev taw qhia ntawm foliation. Cov xim ntawm slate sib txawv nrog cov impurities nws muaj, thiab cov hlau-cov kabmob slate yog xim liab lossis daj; Carbonaceous sawv daws yuav dub los yog grey; Cov pob zeb uas muaj calcium yuav blister nyob rau hauv lub xub ntiag ntawm hydrochloric acid, yog li lawv feem ntau muab faib raws li lawv cov xim, xws li ntsuab slate, dub slate, calcareous slate, thiab lwm yam. Artificial pob zeb yog ua los ntawm cov uas tsis yog-natural sib tov, xws li cob, cement, iav hlaws, aluminite hmoov, thiab lwm yam, nrog crushed pob zeb nplaum. Artificial pob zeb (tseem hu ua "artificial marble"). Pob zeb Artificial tuaj tawm hauv Tebchaws Meskas 30 xyoo dhau los. Qhov ntxov tshaj plaws ntawm kev siv cov khoom siv pob zeb ua cov khoom siv kho kom zoo nkauj hauv Suav teb yog nyob rau hauv qee lub nroog tsim kho ntug hiav txwv nyob rau nruab nrab -1990s, thiab nws tau nrov nrov ob peb xyoos tom qab.
Lub pob zeb kab lis kev cai yog ib hom pob zeb ntuj ntxhia, uas slate, sandstone thiab quartz pob zeb tau ua tiav rau hauv cov khoom siv hauv tsev. Cultural pob zeb cov ntaub ntawv yog ib qho nyuaj, ci xim, nplua nuj nyob rau hauv kev ntxhib los mos thiab txawv nyob rau hauv style, thiab muaj cov yam ntxwv ntawm compression tsis kam, hnav tsis kam, hluav taws kub tsis kam, txias tsis kam, corrosion kuj thiab tsawg nqus dej.
Cov pob zeb hu ua marble hais txog sedimentary lossis metamorphic carbonate pob zeb, suav nrog marble, dolomite, limestone, sandstone, shale thiab slate. Piv txwv li, Tuam Tshoj tus nto moo dawb marble yog dolomite tsim nyob rau hauv Fangshan, Beijing, Yunnan marble yog lub marble tsim nyob rau hauv Dali County, thiab nto moo Dandong ntsuab yog serpentinized skarn. Ib yam li ntawd, txhua yam pob zeb magmatic, xws li andesite, diabase, chlorite thiab gneiss, uas yog mined li pob zeb, hu ua granite. Piv txwv li, dawb granite nyob rau hauv Beijing Baihujian yog granite, Jinan Qingqing yog gabbro, thiab dub granite nyob rau hauv Qingdao yog diabase.
Artificial pob zeb yog ib hom khoom siv kho kom zoo nkauj. Raws li qhov sib txawv binders siv, nws tuaj yeem muab faib ua cov pob zeb pob zeb thiab cov pob zeb inorganic. Raws li cov txheej txheem tsim khoom sib txawv, nws tuaj yeem muab faib ua plaub hom: polyester dag marble, cov khoom sib xyaw marble, silicate dag marble thiab sintered dag marble.
