Kwihlabathi lamatye endalo, i-granite imele njengophawu lokuqina nokuguquguquka. Ukususela kwizikhumbuzo zamandulo ukuya kwizakhiwo ezinde zanamhlanje, eli litye liyi-igneous liye labonakalisa ukubaluleka kwalo kwiindlela ezininzi. Kodwa yintoni kanye kanye eyenza i-granite ibe yekhetheke kangaka? Impendulo ikwindlela yayo ekhethekileyo yeekhemikhali kunye neempawu zomzimba eziphawulekayo eziyahlula kwamanye amatye.
Ukwakheka kweekhemikhali zeGranite
Iimpawu ezibalaseleyo zeGranite ziqala kwinqanaba leemolekyuli. Eli litye lirhabaxa lenziwe ikakhulu ziiminerali ezintathu: iquartz, ifeldspar, kunye ne-mica. I-Quartz, equlathe i-60-70% yokwakheka kwegranite, yiyo enika ilitye ubulukhuni bayo obudumileyo kunye nokumelana nokukrweleka. I-Feldspar, eyenza i-12-15% yokwakheka, isebenza njengesihlanganisi, ibamba ilitye kunye kwaye inegalelo kumandla alo ngokubanzi. I-Mica, nangona ikhona ngobuninzi obuncinci, yongeza kwimbonakalo eyahlukileyo yegranite ngeempawu zayo ezikhanyayo.
Ulwakhiwo oluthile lweekhemikhali zegranite luquka i-silicon dioxide (SiO₂) kwi-60-70%, i-aluminium oxide (Al₂O₃) kwi-12-15%, kunye nezixa ezincinci ze-potassium oxide (K₂O), i-sodium oxide (Na₂O), i-calcium oxide (CaO), i-iron oxide (Fe₂O₃), kunye ne-magnesium oxide (MgO). Olu xube lwahlukileyo lweeminerali kunye nee-oxides yilo lunika i-granite ukuqina kwayo okumangalisayo kunye nokumelana nemozulu.
Iimpawu Zomzimba Ezibalulekileyo
Ngaphandle kokwakheka kwayo ngamakhemikhali, igranite ineempawu ezibonakalayo ezimangalisayo ezenza ukuba ilungele ukusetyenziswa ngeendlela ezahlukeneyo. Ngobunzima obuyi-2.6-2.7g/cm³, igranite inzima kwaye yomelele, iyakwazi ukuxhasa ubunzima obukhulu ngaphandle kokuqhekeka okanye ukuguquka. Izinga layo lokufunxa amanzi lingaphantsi kwe-0.5%, nto leyo eyenza ukuba imelane kakhulu nomonakalo womswakama kunye nokudaya xa ivalwe ngokufanelekileyo.
Enye yezona mpawu zibalulekileyo zegranite bubulukhuni bayo, obuhlala bulingana ne-6-7 kwisikali seMohs. Oku kuyibeka ngaphantsi nje kwedayimani, i-corundum, kunye ne-topaz, nto leyo eyenza ukuba imelane kakhulu nemikrwelo kunye nokuguguleka. Obu bulukhuni bungaqhelekanga bunxulumene ngqo nomxholo wayo we-quartz, odlala indima ebalulekileyo ekumiseleni ukusebenza kwelitye kwizicelo zoshishino.
Impembelelo yoMxholo weQuartz ekusebenzeni kakuhle kokugaya
Kwiindawo zoshishino, umxholo we-quartz kwi-granite unefuthe elithe ngqo ekusebenzeni kakuhle. Izifundo zibonise ukuba kuyo yonke i-10% yokwanda komxholo we-quartz, kukho ukunyuka kwe-8.5% kwinqanaba lokususwa kwezinto ngexesha lemisebenzi yokusila. Olu lwalamano lubaluleke kakhulu ekuvelisweni kwezinto ezichanekileyo kunye nezixhobo apho i-granite isetyenziswa njengezinto ezisisiseko.
Ubungakanani be-quartz ephezulu abuphuculi nje kuphela ukusebenza kakuhle kokusila kodwa bukwanegalelo ekuzinzeni kwelitye. Oku kwenza i-granite ibe lukhetho oluhle kakhulu kwizixhobo zokulinganisa ngokuchanekileyo, ezifana neepleyiti zomphezulu kunye neebhentshi ze-optical, apho ukugcina ubungakanani obuchanekileyo kubalulekile.
Izinto Ezikhethwayo zeNordic zeHigh-Feldspar Granite
Kumantla Yurophu, ingakumbi kumazwe afana neNorway neSweden, kukho ukhetho olukhethekileyo kwiindidi zegranite ezinefeldspar ephezulu. Umzekelo ophawulekayo yiLundhs Blue granite, equlethe i-feldspar engama-35-40%. Lo mxholo we-feldspar uphezulu unika eli litye inkangeleko eyahlukileyo eluhlaza okwesibhakabhaka-ngwevu eye yafunwa kakhulu kwizicelo zokwakha kunye noyilo.
Ukukhethwa kwe-granite ye-high-feldspar yaseNordic akubangelwanga bubuhle bayo kuphela kodwa kukwabangelwa ziingenelo zayo ezisebenzayo. I-Feldspar inegalelo ekusebenzeni kakuhle kwelitye, okwenza kube lula ukulisika nokulibumba ngelixa ligcina ulungelelwaniso lwesakhiwo salo. Olu lungelelwaniso lobuhle kunye nokusebenza kwalo lwenze ukuba i-Lundhs Blue kunye ne-granites ezifanayo zibe lukhetho oludumileyo kuyo yonke into ukusuka kwiikhawuntara ukuya kwiiplanga kwiiprojekthi zokwakha eziphezulu.
Imigangatho ye-ASTM C615: Ukuqinisekisa Umgangatho kunye nokuNgaguquguquki
Ukuqinisekisa umgangatho kunye nokuhambelana kwegranite esetyenziswa ekwakheni nakwimisebenzi yemizi-mveliso, i-American Society for Testing and Materials (ASTM) imisele imigangatho ye-ASTM C615. Le migangatho ichaza iimfuno zelitye legranite, kuquka ubuncinci bomxholo we-SiO₂ we-65%, nto leyo ibalulekileyo ekuqinisekiseni ukuqina nokusebenza kwelitye.
I-ASTM C615 igubungela iinkalo ezahlukeneyo zegranite, kubandakanya iimpawu zezinto ezibonakalayo, iisampulu, uvavanyo, kunye nesatifikethi. Ngokulandela le migangatho, abavelisi kunye nababoneleli banokuqinisekisa ukuba iimveliso zabo zegranite ziyahlangabezana neemfuno zomgangatho ophezulu wokuqina, ukuqina, kunye nozinzo olulinganayo. Ngaphaya koKwakha: Igranite kwiTekhnoloji yanamhlanje
Nangona i-granite yaziwa kakhulu ngokusetyenziswa kwayo ekwakheni nasekuyileni izakhiwo, ukusetyenziswa kwayo kudlulela ngaphaya kwezi ndlela zemveli zokusetyenziswa. Kwicandelo lobuchwepheshe banamhlanje, i-granite idlala indima ebalulekileyo kubunjineli bokuchaneka kunye nokuvelisa.
Esinye isicelo esingalindelekanga sikwicandelo loyilo lojongano lomsebenzisi, apho izixhobo ze-AEM Granite UI ziye zaba yimigangatho yeshishini. Ezi zixhobo, ezibizwa ngokuba ziqinile kwaye zithembekile, zisetyenziswa ekuphuhliseni iinkqubo zolawulo lomxholo kunye namava edijithali. Ukufana ne-granite kubonisa uzinzo kunye nokuqina okufunwa ngabaphuhlisi kwezi zakhiwo ze-UI.
Impembelelo yoKumbiwa kunye nokuQhutywa kweGranite kwiNdalo
Njengakwezinye izixhobo zendalo, ukukhutshelwa nokulungiswa kwegranite kunefuthe kwindalo esingqongileyo elijongwa ngakumbi lishishini. Iindlela zanamhlanje zokumba imigodi zijolise ekunciphiseni umngcipheko wendalo, kunye neenkampani ezisebenzisa izicwangciso zokubuyisela iindawo ezimbiwe kwimeko yazo yendalo emva kokuba imisebenzi iphelile.
Ngokuphathelele ukuzinza, ukuhlala ixesha elide kwegranite lilungelo elikhulu. Izakhiwo ezakhiwe ngegranite zinokuhlala iinkulungwane ezininzi, zinciphisa isidingo sokutshintshwa rhoqo kunye neendleko ezinxulumene nokusingqongileyo. Ukongeza, ukumelana nobushushu kwegranite kwenza ukuba ibe lukhetho olusebenzisa amandla amaninzi ekwakheni iifacade, lunceda ekulawuleni amaqondo obushushu angaphakathi kwaye lunciphise iindleko zokufudumeza nokupholisa.
Ikamva leGranite kwiLizwe elitshintshayo
Njengoko sijonge kwikamva, i-granite iyaqhubeka nokuziqhelanisa neemfuno zoluntu ezitshintshayo. Ubuchule bokulungisa izinto buyenza i-granite ibe nokuguquguquka ngakumbi kunangaphambili, nto leyo evumela ukuba ikwazi ukunqunyulwa kancinci kunye noyilo oluntsonkothileyo. Oku akupheleli nje ekwandiseni amathuba obuhle kodwa kunciphisa neendleko zokusetyenziswa kwezinto kunye nezothutho.
Kwicandelo lokwakha okuzinzileyo, i-granite iyaziwa ngakumbi ngenxa yeenzuzo zayo zokusingqongileyo. Ukwakheka kwayo kwendalo kuyenza ibe yinto yokwakha engenabungozi, engenamitha, kwaye iipropati zayo zobunzima bobushushu zinegalelo ekusebenziseni amandla kakuhle kwizakhiwo. Njengoko ishishini lokwakha lisiya kwiindlela ezizinzileyo, indima ye-granite isenokukhula ibe nkulu nangakumbi.
Isiphelo: Ukubhenela Okungapheliyo kweGranite
Ukususela kwimilo yayo entsonkothileyo yeekhemikhali ukuya kwizicelo zayo ezahlukeneyo kushishino lwanamhlanje, igranite ihlala iyinto ekhethwayo kwabo bafuna ukuqina, ubuhle, kunye nokusebenza kakuhle. Indibaniselwano yayo eyahlukileyo yeempawu zomzimba, kunye nokuguquguquka kwayo kobuhle, iqinisekisa ukuba igranite iya kuqhubeka iyinto ebalulekileyo ekwakheni, kuyilo, nakubuchwepheshe kwiminyaka ezayo.
Njengoko sihlolisise iinkalo ezahlukeneyo zegranite, ukususela kwimilo yayo yeeminerali ukuya kwimpembelelo yayo ekusebenzeni kakuhle kokusila, kuyacaca ukuba eli litye lendalo lingaphezulu kakhulu kunezixhobo zokwakha. Lingqina leenkqubo zejoloji yoMhlaba kunye nesikhumbuzo sendlela izixhobo zendalo ezinokusetyenziswa ngayo ukuhlangabezana neemfuno zabantu ngeendlela ezizinzileyo nezintsha.
Nokuba uyawuthanda umfanekiso wesikhumbuzo sembali, usebenza ngezixhobo ezichanekileyo, okanye usebenzisana neenkqubo ze-UI zanamhlanje, impembelelo yegranite ijikeleze thina. Ubuhle bayo obungapheliyo kunye neempawu zayo ezihlala ixesha elide ziqinisekisa ukuba igranite iya kuhlala ilitye lesiseko lempumelelo yoluntu kwizizukulwana ezizayo.
