Ezweni lamatshe emvelo, i-granite iwuphawu lokuqina nokuguquguquka. Kusukela ezikhumbuzweni zasendulo kuya ezakhiweni eziphakeme zesimanje, leli dwala eliyi-igneous liye lafakazela ukubaluleka kwalo ezinhlotsheni eziningi. Kodwa yini ngempela eyenza i-granite ibe ekhethekile kangaka? Impendulo itholakala ekwakhekeni kwayo kwamakhemikhali okuhlukile kanye nezakhiwo zayo ezibonakalayo eziphawulekayo eziyenza ihluke kwamanye amatshe.
Ukwakheka Kwamakhemikhali Kwe-Granite
Izici ezivelele ze-granite ziqala ezingeni lama-molecule. Leli dwala elinohlamvu oluqinile lakhiwe ngokuyinhloko ngamaminerali amathathu: i-quartz, i-feldspar, ne-mica. I-Quartz, equkethe u-60-70% wokwakheka kwe-granite, yiyo enika itshe ubulukhuni balo obudumile kanye nokumelana nokuklwebheka. I-Feldspar, eyakha u-12-15% wokwakheka, isebenza njengesihlanganisi, ibamba idwala ndawonye futhi inegalelo emandleni alo jikelele. I-Mica, nakuba ikhona ngobuningi obuncane, yenezela ekubukekeni okuhlukile kwe-granite ngezakhiwo zayo ezikhanyayo.
Ukwakheka kwamakhemikhali athile e-granite kuhlanganisa i-silicon dioxide (SiO₂) ku-60-70%, i-aluminium oxide (Al₂O₃) ku-12-15%, kanye namanani amancane e-potassium oxide (K₂O), i-sodium oxide (Na₂O), i-calcium oxide (CaO), i-iron oxide (Fe₂O₃), kanye ne-magnesium oxide (MgO). Le nhlanganisela eyingqayizivele yamaminerali nama-oxide yikona okunikeza i-granite ukuqina kwayo okumangalisayo kanye nokumelana nesimo sezulu.
Izici Zomzimba Ezibalulekile
Ngaphandle kokwakheka kwayo ngamakhemikhali, i-granite inezakhiwo ezimangalisayo zomzimba ezenza ifaneleke kakhulu ezinhlotsheni eziningi zokusetshenziswa. Njengoba inobukhulu obungu-2.6-2.7g/cm³, i-granite inzima futhi inamandla, ikwazi ukusekela isisindo esikhulu ngaphandle kokuqhekeka noma ukuguquka. Izinga layo lokumunca amanzi lingaphansi kuka-0.5%, okwenza imelane kakhulu nomonakalo womswakama kanye nokudaya uma ivalwe kahle.
Esinye sezimpawu zomzimba zegranite eziphawuleka kakhulu ubulukhuni bayo, obuvame ukuba ngu-6-7 esikalini sikaMohs. Lokhu kuyibeka ngaphansi nje kwamadayimane, i-corundum, ne-topaz, okwenza imelane kakhulu nokuklwebheka nokuguguleka. Lobu bulukhuni obungavamile buhlobene ngqo nokuqukethwe kwayo kwe-quartz, okudlala indima ebalulekile ekunqumeni ukusebenza kwetshe ezisetshenziswa ezimbonini.
Umthelela Wokuqukethwe Kwe-Quartz Ekusebenzeni Kahle Kokugaya
Ezindaweni zezimboni, okuqukethwe yi-quartz kwe-granite kunomthelela oqondile ekusebenzeni kahle kokucubungula. Izifundo zibonise ukuthi kukho konke ukwanda okungu-10% kokuqukethwe kwe-quartz, kukhona ukwanda okungu-8.5% kwesilinganiso sokususwa kwezinto ngesikhathi sokugaya. Lobu budlelwano bubaluleke kakhulu ekukhiqizweni kwezingxenye ezinembile namathuluzi lapho i-granite isetshenziswa khona njengezinto eziyisisekelo.
Okuqukethwe okuphezulu kwe-quartz akugcini nje ngokuthuthukisa ukusebenza kahle kokugaya kodwa futhi kunegalelo ekuzinzeni kobukhulu betshe. Lokhu kwenza i-granite ibe ukukhetha okuhle kakhulu kwamathuluzi okulinganisa ngokunemba, njengamapuleti obuso namabhentshi okukhanya, lapho ukugcina ubukhulu obuqondile kubalulekile khona.
Izintandokazi zeNordic ze-High-Feldspar Granite
ENyakatho Yurophu, ikakhulukazi emazweni afana neNorway neSweden, kunokukhetha okuhlukile kwezinhlobo zegranite ezine-feldspar ephezulu. Isibonelo esiphawulekayo yi-Lundhs Blue granite, equkethe i-feldspar engu-35-40%. Lokhu okuqukethwe okuphezulu kwe-feldspar kunikeza itshe ukubukeka okuhlukile okuluhlaza okwesibhakabhaka okumpunga okuye kwafunwa kakhulu kokubili kwezicelo zokwakha kanye nokuklama.
Ukuthanda kwe-Nordic i-granite ye-high-feldspar akuveli nje kuphela ekukhangeni kwayo kobuhle kodwa futhi nasezinzuzweni zayo ezisebenzayo. I-Feldspar inegalelo ekusebenzeni kahle kwetshe, okwenza kube lula ukulisika nokulibumba ngenkathi kugcinwa ubuqotho besakhiwo salo. Lokhu kulinganisela kobuhle nokusebenza kwenze i-Lundhs Blue kanye ne-granite efanayo yaba ukukhetha okuthandwayo kukho konke kusukela kuma-countertop kuya ekumbozweni kwemiklamo yokwakha ephezulu.
Izindinganiso ze-ASTM C615: Ukuqinisekisa Ikhwalithi Nokuhambisana
Ukuqinisekisa ikhwalithi kanye nokuvumelana kwe-granite esetshenziswa ekwakheni nasezimbonini, i-American Society for Testing and Materials (ASTM) isungule amazinga e-ASTM C615. Lezi zindinganiso zichaza izidingo zamatshe osayizi we-granite, okuhlanganisa nokuqukethwe okungenani kwe-SiO₂ okungu-65%, okubalulekile ekuqinisekiseni ukuqina nokusebenza kwetshe.
I-ASTM C615 ihlanganisa izici ezahlukahlukene ze-granite, okuhlanganisa izici zezinto ezibonakalayo, ukusampula, ukuhlolwa, kanye nesitifiketi. Ngokunamathela kulezi zindinganiso, abakhiqizi nabahlinzeki bangaqinisekisa ukuthi imikhiqizo yabo ye-granite ihlangabezana nezidingo zekhwalithi ephezulu kakhulu zamandla, ukuqina, kanye nokuqina kobukhulu. Ngale Kokwakhiwa: I-Granite kubuchwepheshe besimanje
Nakuba i-granite yaziwa kabanzi ngokusetshenziswa kwayo ekwakheni nasekwakheni izakhiwo, ukusetshenziswa kwayo kudlulela ngale kwalokhu kusetshenziswa kwendabuko. Emkhakheni wobuchwepheshe besimanje, i-granite idlala indima ebalulekile ekubunjweni nasekukhiqizweni okunembile.
Uhlelo lokusebenza olulodwa olungalindelekile lusemkhakheni wokuklama isikhombimsebenzisi, lapho izingxenye ze-AEM Granite UI sezibe yizindinganiso zemboni. Lezi zingxenye, eziqanjwe ngokuqina kwazo nokuthembeka kwazo, zisetshenziswa ekuthuthukiseni izinhlelo zokuphatha okuqukethwe kanye nokuhlangenwe nakho kwedijithali. Ukufana ne-granite kubonisa ukuzinza nokuqina okufunwa ngabathuthukisi kulezi zinhlaka ze-UI.
Umthelela Wezemvelo Wokuqoqwa Nokucutshungulwa Kwe-Granite
Njenganoma yimuphi umthombo wemvelo, ukukhishwa nokucutshungulwa kwe-granite kunemiphumela emvelweni exazululwa kabanzi yimboni. Amasu esimanje okumba amatshe ahlose ukunciphisa ukuthinteka kwemvelo, lapho izinkampani zisebenzisa izinhlelo zokuvuselela izindawo ezimbiwe esimweni sazo semvelo ngemva kokuphela kwemisebenzi.
Ngokuphathelene nokusimama, ukuhlala isikhathi eside kwe-granite kuyinzuzo enkulu. Izakhiwo ezakhiwe nge-granite zingahlala amakhulu eminyaka, kunciphisa isidingo sokushintsha njalo kanye nezindleko zemvelo ezihambisanayo. Ngaphezu kwalokho, ukumelana nokushisa kwe-granite kwenza kube ukukhetha okonga amandla okwakha ama-facade, okusiza ukulawula amazinga okushisa angaphakathi nokunciphisa izindleko zokushisa nokupholisa.
Ikusasa Le-Granite Ezweni Elishintshayo
Njengoba sibheke esikhathini esizayo, i-granite iyaqhubeka nokuzivumelanisa nezidingo zomphakathi ezishintshayo. Ubuchwepheshe bokucubungula benza i-granite ibe nokuguquguquka okukhulu kunanini ngaphambili, okuvumela ukusika okuncane kanye nemiklamo eyinkimbinkimbi kakhulu. Lokhu akugcini nje ngokwandisa amathuba okubukeka kodwa futhi kunciphisa izindleko zokusetshenziswa kwezinto kanye nezokuthutha.
Emkhakheni wokwakha okusimeme, i-granite iyaziwa kakhulu ngezinzuzo zayo zemvelo. Ukwakheka kwayo kwemvelo kuyenza ibe yinto yokwakha engenabo ubuthi, engenamisebe, futhi izakhiwo zayo zokushisa zinegalelo ekusebenzeni kahle kwamandla ezakhiweni. Njengoba imboni yokwakha iqhubekela phambili emikhubeni esimeme kakhudlwana, indima ye-granite cishe izokhula ibe nkulu nakakhulu.
Isiphetho: Ukukhanga Okungapheli Kwe-Granite
Kusukela ekwakhekeni kwayo okuyinkimbinkimbi kwamakhemikhali kuya ekusetshenzisweni kwayo okuhlukahlukene embonini yanamuhla, i-granite isalokhu iyinto ekhethwayo kulabo abafuna ukuqina, ubuhle, kanye nokusebenza kahle. Inhlanganisela yayo eyingqayizivele yezakhiwo zomzimba, kanye nokuguquguquka kwayo kobuhle, iqinisekisa ukuthi i-granite izoqhubeka nokuba yisisekelo ekwakheni, ekuklameni, kanye nasebuchwephesheni iminyaka ezayo.
Njengoba sihlole izici ezahlukahlukene ze-granite, kusukela ekwakhekeni kwayo kwamaminerali kuya emthonjeni wayo ekusebenzeni kahle kokugaya, kusobala ukuthi leli tshe lemvelo lingaphezu nje kwezinto zokwakha. Liwubufakazi bezinqubo ze-geological zoMhlaba kanye nesikhumbuzo sendlela imithombo yemvelo engasetshenziswa ngayo ukuhlangabezana nezidingo zabantu ngezindlela eziqhubekayo nezintsha.
Kungakhathaliseki ukuthi uyawuthanda umbukiso wesikhumbuzo womlando, usebenza ngamathuluzi anembile, noma usebenzisana nezinhlelo ze-UI ezisezingeni eliphezulu, ithonya le-granite lisizungezile. Ukukhanga kwayo okungapheli kanye nezakhiwo zayo ezihlala njalo kuqinisekisa ukuthi i-granite izohlala iyitshe lesisekelo lempumelelo yomuntu ezizukulwaneni ezizayo.
