Uma kukhulunywa ngezingxenye ze-granite ezinembile, umuntu angase azibuze ukuthi lezi zingxenye zivame ukugqwala yini. Kuyindaba efanelekile, njengoba ukugqwala kungonakalisa ubuqotho nokunemba kwezingxenye ezinembile, futhi ekugcineni kungaholela ekwehlulekeni kwazo.
Kodwa-ke, izindaba ezinhle ukuthi izingxenye ze-granite ezinembile azikwazi ukugqwala nhlobo. Lokhu kungenxa yokuthi i-granite iyinto eqinile kakhulu futhi ehlala isikhathi eside emelana nokugqwala kakhulu, okuhlanganisa nokugqwala.
I-Granite uhlobo lwedwala eliyi-igneous elakhiwe kakhulu yi-quartz, i-feldspar, ne-mica. Lakhiwa ukupholisa nokuqina kwe-magma noma i-lava, futhi laziwa ngobulukhuni bayo obumangalisayo nokuqina kwayo. I-Granite iphinde imelane kakhulu nokuguguleka, okwenza ibe yinto efanelekile yezingxenye ezinembile ezidinga izinga eliphezulu lokunemba nokuvumelana.
Isizathu sokuthi i-granite ingagqwali ukuthi ayinayo i-iron noma i-iron oxide, okuyizona zinto eziyinhloko ezibangela ukwakheka kokugqwala. Ukugqwala uhlobo lokugqwala okwenzeka lapho insimbi noma insimbi ivezwa umoya-mpilo kanye nomswakama, okuholela ekwakhekeni kwe-iron oxide. Ngokuhamba kwesikhathi, le iron oxide ingabangela ukugqwala ukusabalala, okuholela ekulimaleni kwesakhiwo engxenyeni ethintekile.
Ngenxa yokuthi izingxenye ze-granite ezinembile azinawo insimbi noma insimbi, azikwazi ukugqwala. Lokhu kuzenza zibe ukukhetha okuhle kokusetshenziswa ezinhlobonhlobo zezicelo, okuhlanganisa imishini yokulinganisa, amathuluzi omshini, kanye nama-jig kanye nezinto zokuhlanganisa.
Ngaphezu kokumelana nokugqwala, izingxenye ze-granite enembile nazo zinikeza ezinye izinzuzo eziningi. Okokuqala, zizinzile kakhulu futhi azikhuli noma zinciphe ngenxa yezinguquko zokushisa noma umswakama. Lokhu kusho ukuthi zingagcina ukunemba kwazo nokunemba kwazo ngokuhamba kwesikhathi, ngisho nangaphansi kwezimo zemvelo ezahlukahlukene.
Izingxenye ze-granite eziqondile nazo ziyamelana kakhulu nokuguguleka nokuklebhuka, okwenza zibe inketho engabizi kakhulu yokusetshenziswa isikhathi eside. Zidinga ukulungiswa okuncane noma okungenakho ukulungiswa, futhi zingamelana nokusetshenziswa okukhulu ngaphandle kokubonisa izimpawu zokuguguleka noma ukuwohloka.
Sekukonke, uma ufuna izingxenye eziqondile ezihlala isikhathi eside futhi ezinokwethenjelwa, izingxenye ze-precision granite ziyisinqumo esihle kakhulu. Akugcini nje ngokuba ziqinile kakhulu futhi zimelana nokugqwala, kodwa futhi zinikeza ukuzinza nokunemba okumangalisayo okungagcinwa ngokuhamba kwesikhathi. Kungakhathaliseki ukuthi usebenza embonini, ezimotweni, ezindizayo, noma kunoma yimuphi omunye umkhakha odinga izingxenye eziqondile kakhulu, izingxenye ze-precision granite ziqinisekile ukuthi zizoletha imiphumela oyidingayo.
