Ntau yam kev faib tawm thiab cov yam ntxwv ntawm Granite

Qhov kuv nyeem Ua ntej Xim

Thaum tus neeg siv khoom xa kuv qhov kev xav tau granite, xim yog qhov kawg uas kuv paub meej. Xim yog qhov yooj yim tshaj plaws rau kev txiav txim siab los ntawm lub xov tooj duab thiab qhov yooj yim tshaj plaws rau kev qhia tsis tseeb nrog cov qauv me me, yog li nws tsis tau txais thawj qhov chaw ntawm kuv daim ntawv teev npe. Qhov kuv nyeem ua ntej yog cov ntxhia sib xyaw thiab cov qauv nplej. Ob yam no qhia kuv tias lub pob zeb yuav txiav li cas, nws yuav siv li cas, seb nws puas yuav haus cov sealer, thiab yuav ua li cas nws thiaj li muaj sia nyob ntawm chav dej da dej uas muaj dej thiab xab npum txhua hnub.

Granite tsis yog ib qho khoom siv nrog ib txheej ntawm tus lej. Nws yog ib tsev neeg ntawm cov pob zeb uas tsis muaj zog uas txias maj mam hauv qab lub ntiaj teb lub pob zeb, thiab cov chemical ntawm magma ntxiv rau qhov ceev ntawm qhov txias txias txiav txim siab yuav luag txhua yam khoom uas tus neeg yuav khoom them rau. Ob lub slabs tuaj yeem nqa lub npe granite ntawm daim ntawv teev nqi thiab tseem coj txawv txawv thaum lawv ncav cuag tus neeg tsim khoom. Tias yog vim li cas kuv kho qhov kev faib tawm raws li cov cuab yeej ua haujlwm es tsis txhob siv cov lus hauv geology. Tib tus cwj pwm ua haujlwm rau tus tswv tsev uas hnyav cov kev xaiv countertop thiab rau ib qhov project buyer tso ib qho kev txiav txim export: nyeem lub pob zeb ua ntej koj nyeem tus nqi.

Kev faib tawm los ntawm Mineral: Quartz, Feldspar, thiab Mica

Kev faib cov pob zeb hauv av yog ib tus neeg muag khoom feem ntau luam tawm ntawm daim ntawv spec. Granite yog tsim los ntawm peb cov khoom xyaw tseem ceeb, quartz, feldspar, thiab mica, nrog me me ntawm cov ntxhia tsaus nti xws li hornblende hauv qee hom. Qhov kev faib ua feem thiab hom ntawm txhua yam khoom hloov pauv tus yam ntxwv ntawm lub pob zeb. Thaum ib daim ntawv teev npe hu ib yam dab tsi dub granite, muscovite granite, hornblende granite, los yog mica granite, nws yog piav qhia txog cov minerals uas muaj los yog sawv tawm, thiab txhua tus ntawm cov npe no muaj cov txheej txheem kev coj ua.

Quartz Teeb Lub Hardness Pem Teb

Quartz yog cov iav, translucent grey ntxhia tawg los ntawm lub pob zeb, thiab nws yog vim li cas granite nyuaj. Ntawm Mohs nplai, granite zaum ib ncig ntawm 6 txog 7, zoo tshaj cov hlau zoo tib yam. Quartz yog cov ntxhia ua haujlwm feem ntau, vim tias quartz nws tus kheej yog 7 thiab tsis khawb hauv chav ua noj riam. Thaum kuv pom ib lub slab uas muaj ntau qhov zoo- faib quartz, kuv paub ob yam nyob rau pem hauv ntej: nws yuav siv lub ci ci, thiab nws yuav khaws cov polish vim tsis muaj dab tsi hauv tsev ib txwm yuav khawb nws. Los ntawm cov ntsiab lus ntawm kev saib, cov ntsiab lus quartz yog thawj lub thawv kuv kos rau ntawm daim ntawv qib. Ib qho granite uas luv luv ntawm quartz tseem yuav zoo li granite, tab sis nws yuav npub sai dua thiab pom hnav ntawm lub txee tsis khoom.

Feldspar Teeb Xim thiab Cleavage

Feldspar yog cov ntxhia tshaj plaws hauv granite, thiab nws yog dab tsi muab pob zeb nws cov xim. Alkali feldspar sau paj yeeb, dawb, thiab qab zib, thaum plagioclase feldspar khiav dawb mus rau grey. Lub npe ntawm lub slab, txawm tias liab liab lossis xiav hlaws, feem ntau yog ib zaj dab neeg hais txog qhov twg feldspar dominates thiab dab tsi cov ntxhia pob zeb tint nws. Feldspar tseem ceeb rau qib rau qhov laj thawj tsis tshua pom tseeb: nws muaj cov dav hlau tawg, cov lus qhia tiaj tus raws li cov ntxhia sib cais. Ib lub pob zeb uas muaj cov pob zeb loj feldspar tuaj yeem saib zoo nkauj, tab sis cov dav hlau cleavage no tsis muaj zog. Kuv xyuas seb cov feldspar puas zoo thiab cuam tshuam nrog quartz lossis seb nws zaum hauv cov pob zeb loj, cais. Fine interlocked feldspar txhais tau hais tias lub suab slab. Cov pob zeb loj sib cais txhais tau tias yog ib qho slab uas yuav nti los ntawm ib lub khob ntawm txoj kab tsis ncaj ncees lawm.

Mica thiab Dark Minerals teeb qhov kev pheej hmoo

Mica zoo li nyias, ci, flakes tsaus, feem ntau biotite, thiab nyob rau hauv ib co pob zeb ib tug sib zog muscovite. Nws yog qhov softest ntawm peb cov khoom xyaw tseem ceeb thiab qhov kuv saib zoo tshaj plaws. Mica flakes yog platy, yog li lawv faib tau yooj yim thiab zaum zoo li cov ntawv me me hauv pob zeb. Ib kab ntawm mica yog qhov qub thiab tsis muaj mob. Ib qho granite tau piav qhia tias yog mica granite, qhov twg mica yog cov pob zeb zoo nkauj, nyiam flake yooj yim dua thiab nqus dej raws cov dav hlau mica. Rau qhov kev txiav txim xa tawm mus rau chav dej ntub, kuv xav kom cov ntsiab lus mica qis thiab sib npaug sib npaug es tsis yog nyob hauv pawg. Hornblende, lwm cov ntxhia tsaus nti, yog ib qho nyuaj tshaj li mica thiab tsis tshua muaj kev txhawj xeeb, yog li hornblende granite feem ntau coj zoo dua hauv dej dua li mica- hnyav.

Kev faib tawm los ntawm Grain Structure: Fine, Medium, Coarse, thiab Porphyritic

Qhov thib ob kev faib tawm yog hais txog cov qauv, thiab nws piav txog qhov loj thiab kev npaj ntawm cov pob zeb hauv av ntau dua li cov nplej ua los ntawm. Cov qoob loo loj yog teem los ntawm qhov txias txias: qhov qeeb qeeb ntawm magma txias, qhov loj dua cov muaju muaj sij hawm loj hlob. Cov qauv tseem ceeb vim tias qhov loj ntawm cov nplej tswj qhov ntom ntom, lub zog, nqus dej, thiab txawm tias lub polish zoo li cas. Cov neeg muab khoom faib cov granite rau hauv nplua -grained, nruab nrab-grained, coarse-grained, thiab porphyritic hom, thiab txhua tus coj txawv me ntsis thaum nws txiav thiab ntsia.

Zoo-Grained Granite

Fine-grained granite muaj cov nplej hauv qab li 1 millimeter, nruj txaus uas cov muaju kaw ua ke nrog yuav luag tsis pom qhov khoob. Qhov no yog daim ntawv ntom ntom thiab muaj zog tshaj plaws ntawm cov khoom siv. Cov duab kuv tau qhia tseem tuav: granite compresses ntawm kwv yees li 100 txog 300 MPa, thiab zoo -grained granite tuaj yeem thawb dhau 300 MPa, thaum khoov lub zog khiav txog 10 mus rau 30 MPa. Cov nplej zoo kuj txhais tau tias tsis muaj porosity, nyob rau hauv thaj tsam ntawm 0.3 mus rau 0.7 feem pua, thiab cov dej tsis haum, nyob ib ncig ntawm 0.15 mus rau 0.46 feem pua. Rau lub txee los yog qhov chaw ntub dej, cov nplej zoo yog qib kuv ncav cuag. Nws polishes kom du, txawm tias ci thiab tiv taus stains vim tias tsis muaj qhov qhib me me rau cov kua nkag. Kev lag luam yog qhov zoo -grained granite feem ntau zaum hauv qib kim dua, vim nws tsis tshua muaj thiab nyuaj rau cov chaw txua txiag zeb hauv cov blocks loj.

Nruab nrab thiab ntxhib Granite

Nruab nrab-grained granite, nrog cov nplej ntawm li 1 thiab 5 millimeters, yog cov neeg ua haujlwm niaj hnub. Nws sib npaug ib qho pom, txaus nyiam lis tiv thaiv lub suab qauv, thiab nws yog dab tsi feem ntau cov qauv lag luam granite poob rau hauv. Coarse-grained granite, nrog cov nplej ntawm li 5 millimeters mus txog 3 centimeters, yog cov khoom siv da dej. Tus neeg siv lead ua yog loj txaus los nyeem ntawm caj npab ntev, uas muab lub siab tawv, speckled saib qee tus neeg yuav khoom xav tau rau lub phab ntsa tshwj xeeb lossis cov lus cog tseg. Lub downside yog tswv yim. Coarser crystals txhais tau hais tias qhib ciam teb me ntsis ntawm cov nplej, kov ntau qhov nqus dej, thiab polished uas nyeem raws li textured es tsis yog daim iav - du. Coarse granite tsis qaug zog, tab sis kuv yuav tsis muab tso rau hauv lub siab - coj chav ua noj los yog ib qho chaw ntub dej yam tsis tau kuaj xyuas seb cov kab lis kev cai nruj npaum li cas nyob rau ntawm cov nplais tag nrho.

Porphyritic Granite

Porphyritic granite yog ib qho uas ua rau thawj zaug - cov neeg yuav khoom, vim nws sib tov ob qhov loj me hauv ib lub pob zeb. Cov muaju loj, hu ua phenocrysts thiab feem ntau feldspar, zaum hauv ib puag ncig zoo li matrix. Cov ntaub ntawv kev ntxhib los mos thaum magma txias maj mam txaus kom loj hlob muaju loj, tom qab ntawd ua tiav kom txias sai dua li qhov seem ntawm cov yaj crystallizes me dua. Visually nws yuav ua tau zoo nkauj. Structurally nws yog ib lub hnab sib xyaw, vim hais tias cov phenocrysts loj zaum ntawm feldspar cleavage dav hlau kuv tau hais ua ntej thaum lub finer matrix nyob ib ncig ntawm lawv nyob twj ywm suab. Thaum kuv muab lub pob zeb porphyritic, kuv tshuaj xyuas seb cov pob zeb loj puas tau zaum zoo thiab tsis muaj cov kab plaub hau tawg nyob ib ncig ntawm lawv cov npoo. Ib tug huv porphyritic slab tuav tau zoo. Ib qho nrog cov phenocryst tawg yuav tawg raws cov kab nrib pleb thaum nws raug txiav thiab polished.

Tig Classification rau hauv Kev Txiav Txim Qib

Tsis muaj qhov no yog kev kawm. Qhov kev faib tawm yog li cas kuv cais thawj - qib slab los ntawm qib thib ob - qib ib thaum tib lub npe lag luam tshwm ntawm ob qhov sib txawv. Tus neeg yuav khoom tuaj yeem pom ob daim ntawv sau nrog tib lub npe, thiab qhov sib txawv ntawm lawv feem ntau yog muab zais rau hauv cov ntxhia sib xyaw thiab cov nplej, tsis yog xim. Ntawm no yog ib ntus kuv ua raws. Ua ntej kuv nyeem cov ntxhia proportions. Tom qab ntawd kuv nyeem cov grain loj thiab uniformity. Tom qab ntawd kuv saib tag nrho cov slab rau qhov tsis ua hauj lwm taw qhia ob qhov kev nyeem ntawv twv ua ntej: mica bands, loj cleavage -feldspar, ntxhib qhib nplej, los yog tawg phenocrysts. Tsis txhob nug kuv tias kuv paub li cas, tab sis ib lub slab uas ua tsis tau ib qho ntawm cov tshev yuav luag ib txwm ua rau muaj teeb meem hauv qab, hauv khw txiav lossis hauv chav dej.

Rau kev txiav txim xa tawm kuv kuj tshawb xyuas qhov sib xws thoob plaws lub batch, tsis yog ntawm ib qho zoo nkauj slab. Tus neeg yuav khoom uas pom zoo ib qho qauv thiab tom qab ntawd tau txais ib lub thawv ntawm cov qib sib xyaw tau them rau qhov zoo uas lawv tsis tau txais. Yog li kuv thov rau cov duab ntawm ob peb slabs los ntawm tib lub thaiv thiab saib seb puas muaj cov ntxhia sib xyaw thiab cov nplej nyob ruaj khov los ntawm ib qho kawg ntawm pawg mus rau lwm qhov. Ib qho thaiv uas quarried huv si tsim cov slabs uas nyeem tib yam, thiab ntau sib xyaw qhia nws qhov sib txawv sai sai thaum koj saib yav dhau los cov xim.

Granite tsuas yog ib tus tswv cuab ntawm tsev neeg pob zeb zoo nkauj, thiab nws tsim nyog paub qhov twg nws zaum txheeb ze rau marble thiab pob zeb engineered ua ntej koj ua pob nyiaj siv. Kuv tau sau daim ntawv qhia dav dua ntawd nyob rau hauv ib qho kev sau cais - rau ntawmkev faib cov pob zeb zoo nkauj, uas yog txoj cai pib thaum koj xaiv ntawm cov tsev neeg cov khoom es tsis yog ntawm cov qib ntawm tib lub pob zeb.

Thaum cov lus nug qib tau txiav txim siab, cov lus nug tom ntej yog seb granite puas yog cov khoom siv rau txoj haujlwm txhua. Rau chav ua noj tshwj xeeb, kuv tau sau cov lus teb ntev dua ntawm seb puas yoggranite countertops yog tiag tiag zoo, uas hnyav lub durability tiv thaiv sealing thiab qhov hnyav. Cov qauv luv luv: cov kev cai qib siab saum toj no txiav txim siab seb qhov muab granite zoo li cas, thiab cov khoom siv txiav txim siab seb granite puas yog tsev neeg nyob hauv thawj qhov chaw.

Cov lej hauv lub rooj ntawd tsis yog kuv li tsim, thiab kuv tsis ua. Cov qoob loo-size bands yog cov qauv geological ntau yam, thiab cov ntaub ntawv lub zog yog los ntawm luam tawm granite specifications: ceev ntawm li 2.63 mus rau 2.75 grams ib cubic centimeter, dej nqus li ntawm 0.15 mus rau 0.46 feem pua, thiab compressive zog ntawm 100 mus rau 300 MPa cov ntaub ntawv zoo tshaj. Kuv khaws cov duab ntawm tes vim tias lawv yog cov neeg yuav khoom tuaj yeem tuav tus neeg muag khoom rau, thiab vim tias lawv tig lo lus tsis meej xws li nyuaj rau hauv tus lej kuv tuaj yeem tshawb xyuas.

Cov lus nug nquag

Dab tsi yog cov pob zeb tseem ceeb hauv granite, thiab qhov twg yog qhov tseem ceeb tshaj plaws rau qib?

Granite yog tsim los ntawm quartz, feldspar, thiab mica, nrog me me ntawm cov minerals tsaus xws li hornblende hauv qee hom. Qhov twg tseem ceeb tshaj plaws nyob ntawm daim ntawv thov. Rau lub countertop, quartz faib yog qhov tseem ceeb, vim quartz nqa lub hardness thiab polish. Rau qhov chaw ntub dej, cov ntsiab lus mica tseem ceeb dua, vim tias mica flakes nqus dej thiab sib cais yooj yim. Feldspar zaum nyob rau hauv nruab nrab: nws muab cov xim, tab sis nws cov dav hlau cleavage yog lub chipping kev pheej hmoo los saib ntawm tej siv lead ua loj.

Dab tsi yog qhov txawv ntawm nplua -grained thiab coarse-grained granite?

Nws yog qhov sib txawv ntawm cov siv lead ua loj, thiab nws hloov li cas lub pob zeb ua haujlwm. Zoo-grained granite muaj nplej nyob rau hauv li 1 millimeters, uas ua rau nws denser, muaj zog, thiab tsawg absorbent, thiab nws polishes mus rau ib tug du, txawm sheen. Coarse-grained granite muaj nplej los ntawm li 5 millimeters mus txog 3 centimeters, uas muab ib tug bold, pom ntau grain tab sis kuj me ntsis qhib ciam teb ntawm cov muaju thiab ib tug ntau textured polish. Rau chav ua noj tsis khoom lossis ib qho chaw ntub dej, kuv lean zoo rau nruab nrab nplej.

porphyritic granite yog dab tsi, thiab nws puas tsis muaj zog?

Porphyritic granite sib tov ob qhov ntau thiab tsawg: cov muaju loj, hu ua phenocrysts thiab feem ntau yog feldspar, zaum hauv cov matrix zoo dua. Nws tsim los ntawm ob- theem ua kom txias keeb kwm. Nws tsis yog qhov tsis muaj zog, tab sis cov pob zeb loj feldspar zaum ntawm cov dav hlau tawg, yog li kuv tshawb xyuas cov kab plaub hau ntawm cov phenocrysts. Ib tug huv porphyritic slab tuav tau zoo. Ib qho nrog cov phenocrysts tawg yuav tawg raws cov kab nrib pleb thaum nws raug txiav thiab polished, yog li ntawd yog thawj zaug kuv xyuas.

Kuv yuav txiav txim siab qib granite li cas thaum ob tus neeg muag khoom hais tib lub npe lag luam?

Tsis quav ntsej lub npe thiab nyeem cov slab. Tib lub npe lag luam tuaj yeem npog cov khoom sib txawv, yog li kuv piv cov ntxhia sib xyaw thiab cov qauv nplej. Nrhiav kom zoo- faib cov quartz, zoo interlocked feldspar, tsawg tawg mica, thiab ib tug grain loj uas haum rau daim ntawv thov. Ib txwm tshuaj xyuas tag nrho cov slab es tsis yog cov qauv me me, thiab tuav tus neeg xa khoom mus rau cov lej luam tawm rau qhov ntom ntom, nqus dej, thiab lub zog compressive. Ib qib yuav tsum ua raws li lub pob zeb, tsis yog los ntawm daim ntawv lo.

Dab tsi yog qib granite kuv yuav tsum xaiv rau chav dej saib iav heev?

Rau ib qho khoom siv uas ua tau raws li dej thiab xab npum txhua hnub, kuv xaiv zoo rau nruab nrab cov nplej nrog qis, sib npaug sib npaug mica thiab ntau quartz. Qhov chaw ntub dej nyiam qhov nqus dej tsawg, yog li cov pob zeb zoo -cov pob zeb hauv 0.15 mus rau 0.46 feem pua ​​yog lub hom phiaj nyab xeeb. Kuv zam mica- hnyav granite thiab ntxhib qhib- pob zeb pob zeb nyob rau hauv qhov chaw, vim hais tias ob qho tib si muab dej thiab noo noo ib txoj kev yooj yim dua nyob rau hauv lub xyoo. Lub pob zeb tsis tas yuav yog qhov kim tshaj plaws ntawm phab ntsa; nws yuav tsum nruj thiab suab.

Qhov Kawg

Granite kev faib tawm tsis yog kev kuaj geology. Nws yog ib hom lus muab qhab nia, thiab ib zaug koj tuaj yeem nyeem tau, cov ntxhia sib xyaw thiab cov nplej qhia koj feem ntau ntawm tus neeg muag khoom tus nqi yuav tsum tau xav txog. Quartz coj lub hardness, feldspar coj cov xim thiab cleavage txaus ntshai, mica coj cov flaking txaus ntshai, thiab grain loj coj cov ntom thiab polish. Kawm nyeem cov plaub yam no ntawm ib daim ntawv qhia tag nrho, thiab koj tuaj yeem qhib cov ntawv xa tawm lossis taug kev mus rau hauv ib lub pob zeb thiab paub tsis pub dhau ib feeb seb qib twg yog tus lej ntawm kab. Qhov ntawd yog ib feem ntawm kev muab khoom kuv nyiam tshaj plaws. Yog tias koj tab tom ua haujlwm los ntawm kev xaiv granite rau ib qhov project, txawm tias nws yog kev khiav ntawm chav dej da dej lossis chav ua noj ib leeg, pab pawg ntawm KA UNITED tuaj yeem taug kev koj los ntawm tib daim tshev ntawm cov slabs tiag tiag ua ntej koj siv ib xees.
