Qhov sib txawv tseem ceeb ntawm quartz thiab quartzite yog quartz siv nyob rau hauv countertop npaj yog engineered pob zeb uas yog molded thiab ci rau hauv slabs nyob rau hauv ib lub Hoobkas, whereas quartzite yog hais txog 90 - 99% ntuj.
Quartz thiab quartzite yog cov ntxhia tseem ceeb uas peb tuaj yeem siv los npaj cov txee. Cov no yog ob qho khoom siv high-end countertop ua los ntawm quartz thiab feem ntau tsis meej pem nrog ib leeg yog li qee tus neeg nyiam siv lawv sib hloov.
Quartz yog dab tsi?
Quartz yog cov ntxhia sib xyaw ua ke ntawm silicon thiab oxygen atoms. Nws muaj silicon dioxide (SiO2) molecules. Nws yog cov ntxhia tshaj plaws nyob rau hauv lub ntiaj teb crust. Txawm hais tias nws muaj SiO2, qhov rov ua dua ntawm cov pob zeb no yog SiO4. Qhov no yog vim hais tias cov qauv tshuaj ntawm quartz muaj ib tug silicon atom bonded rau plaub oxygen atoms nyob ib ncig ntawm nws. Yog li ntawd, lub geometry nyob ib ncig ntawm ib tug silicon atom yog tetrahedral. Txawm li cas los xij, ib qho oxygen atom sib koom ntawm ob lub tetrahedral. Yog li ntawd, cov txheej txheem siv lead ua ntawm cov ntxhia yog hexagonal.
Tsis tas li ntawd, quartz siv lead ua yog chiral. Qhov ntawd txhais tau tias quartz muaj nyob rau hauv ob hom; qhov qub α-quartz thiab kub-kub β-quartz. Daim ntawv alpha tuaj yeem hloov mus rau hauv daim ntawv beta ntawm ib ncig ntawm 573 ° C. Qee hom quartz tsis muaj xim thiab pob tshab, thaum lwm cov ntaub ntawv muaj xim zoo nkauj thiab translucent. Cov xim ntau tshaj plaws ntawm cov pob zeb no yog dawb, grey, ntshav, thiab daj.
Quartz tseem ceeb heev hauv kev npaj cov txee. Hom quartz siv nyob rau hauv countertops yog engineered pob zeb uas tsis yog ntuj. Cov no yog molded thiab ci rau hauv slabs hauv lub hoobkas. Nws muaj 90 - 94% ntawm av quartz nrog 6 - 10% ntawm cov txiv neej ua polymer resins thiab pigments uas khi rau pawg quartz. Vim tias txoj kev khi no, cov pob zeb ua haujlwm muaj qhov tsis muaj qhov ntxeem tau uas tsis tas yuav tsum tau sib khi. Nws kuj yog ib qho kev tiv thaiv zoo tiv thaiv ya raws thiab microbes.
Quartzite yog dab tsi?
Quartzite yog cov ntxhia uas yog thawj zaug ntshiab quartz sandstone. Nws yog ib qho nyuaj, tsis-foliated metamorphic pob zeb. Sandstone hloov mus rau hauv quartzite los ntawm cua sov thiab siab uas cuam tshuam rau tectonic compression nyob rau hauv orogenic siv. Nyob rau hauv nws daim ntawv ntshiab, quartzite tshwm nyob rau hauv dawb mus rau grey xim tab sis nws feem ntau tshwm sim nyob rau hauv ntau yam ntxoov liab thiab liab vim txawv cov nqi ntawm hematite. Txawm li cas los xij, tuaj yeem muaj lwm yam xim, xws li daj, ntsuab, xiav, thiab txiv kab ntxwv tuaj vim muaj lwm yam minerals.
Quartzite tiv taus cov tshuaj tiv thaiv huab cua thiab feem ntau tsim cov ridges thiab hilltops resistant. Nws muaj ze li ntawm cov ntsiab lus ntshiab silica uas muab cov pob zeb nrog cov khoom me me rau cov av, yog li quartzite ridges feem ntau liab qab los yog npog nrog ib txheej nyias ntawm cov av thiab cov nroj tsuag me me. Tsis tas li ntawd, qee qhov quartzite yog tsim los ntawm huab cua-hloov cov khoom noj muaj txiaj ntsig, suav nrog carbonates thiab chlorite, tsim kom muaj loamy, haum fertile, ntiav, thiab pob zeb av.
Quartzite yog lub pob zeb zoo nkauj thiab tuaj yeem siv los npog cov phab ntsa ua cov pobzeb vov tsev, ua hauv pem teb, thiab ua stairs. Kev siv cov khoom siv no rau countertops hauv chav ua noj kuj nthuav dav sai. Ntxiv mus, quartzite yog ib qho nyuaj thiab tiv taus ntau dua rau cov stains piv rau granite. Qee zaum, daim ntawv crushed ntawm quartzite yog qhov tseem ceeb hauv kev tsim kho. Daim ntawv ntshiab heev yog qhov tseem ceeb hauv kev tsim ferrosilicon, muaj silica xuab zeb, silicon, thiab silicon carbide.
Qhov txawv ntawm Quartz thiab Quartzite yog dab tsi?
Quartz thiab quartzite yog cov ntxhia tseem ceeb uas tuaj yeem siv los npaj cov txee. Qhov sib txawv tseem ceeb ntawm quartz thiab quartzite yog quartz siv nyob rau hauv countertop npaj yog engineered pob zeb uas yog molded thiab ci rau hauv slabs nyob rau hauv ib lub Hoobkas, whereas quartzite yog hais txog 90 - 99% ntuj.
Cov hauv qab no qhia txog qhov sib txawv ntawm quartz thiab quartzite hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Quartz vs Quartzite
Quartz yog cov ntxhia hauv cov khoom sib xyaw ua ke ntawm silicon thiab oxygen atoms, thaum quartzite yog cov ntxhia uas yog pob zeb dawb huv quartz sandstone. Qhov sib txawv tseem ceeb ntawm quartz thiab quartzite yog quartz siv nyob rau hauv countertop npaj yog engineered pob zeb uas yog molded thiab ci rau hauv slabs nyob rau hauv ib lub Hoobkas, whereas quartzite yog hais txog 90 - 99% ntuj.
