Iqonga le granite liqonga elenziwe ngegranite. Yenziwe kwilitye elivuthayo, igranite lilitye eliqinileyo, elikristale. Ekuqaleni iqulunqwe nge-feldspar, i-quartz, kunye ne-granite, ifakwe kwi-mineral emnyama enye okanye ngaphezulu, zonke zicwangciswe ngendlela efanayo.
Igranite ikakhulu yenziwe ngequartz, feldspar, kunye ne mica. I-akhawunti ye-Feldspar i-40% -60%, kunye ne-quartz ye-20% -40%. Umbala wayo uxhomekeke kuhlobo kunye nobungakanani bala macandelo. IGranite lilitye elicwebe ngokupheleleyo. I-granite yekhwalithi ephezulu ineenkozo ezintle kunye ezifanayo, isakhiwo esixineneyo, umxholo ophezulu we-quartz, kunye ne-feldspar sheen eqaqambileyo.
I-Granite inomxholo ophezulu we-silica, okwenza ilitye elineasidi. Ezinye iigraniti ziqulethe umkhondo wezinto ezisasazwa ngemitha, ngoko ke ezi ntlobo zegranite kufuneka ziphetshwe ukuze zisetyenziswe ngaphakathi. I-Granite inesakhiwo esixineneyo, i-texture enzima, kwaye iyamelana ne-acids, i-alkalis, kunye nemozulu, okwenza ukuba ilungele ukusetyenziswa kwangaphandle ixesha elide. Igranite inezi mpawu zilandelayo:
1. I-Granite inesakhiwo esixineneyo, amandla aphezulu okucinezela, ukufunxa kwamanzi aphantsi, ubunzima obuphezulu bomhlaba, ukuzinza okuhle kweekhemikhali, kunye nokuqina okuqinileyo, kodwa ukunganyangeki komlilo.
2. Igranite inesakhiwo segranular esineenkozo ezintle, eziphakathi, okanye ezinqabileyo, okanye isakhiwo se-porphyritic. Iinkozo zayo zifana kwaye zilungile, zinezikhewu ezincinci (i-porosity ngokuqhelekileyo yi-0.3% ukuya kwi-0.7%), ukufunxa kwamanzi aphantsi (ngokuqhelekileyo i-0.15% ukuya kwi-0.46%), kunye nokuchasana kakuhle kweqabaka.
3. Igranite iqinile, inobulukhuni be-Mohs obujikeleze i-6 kunye noxinzelelo olusuka kwi-2.63 g/cm³ ukuya kwi-2.75 Uluhlu lwe-g/(cm³) lunamandla oxinzelelo lwe-100-300 MPa, kunye negranite ecolekileyo efikelela kwi-300 MPa. Amandla ayo e-flexural ngokubanzi phakathi kwe-10 kunye ne-30 MPa.
Okwesine, igranite inezinga eliphezulu lesivuno, iyamkeleka kwiindlela ezahlukeneyo zokusetyenzwa, kwaye ineempawu ezigqwesileyo zeslab splicing. Ngapha koko, i-granite ayiphepheki lula, iyenza ilungele iinjongo zokuhombisa ngaphandle.
Ukugcina iqonga lemarble (i-marble slab) lifuna ukumisela ukunyamezela kunye neemfuno zokugcinwa kweqonga le-marble langoku, kunye nokugqiba ukuba indawo yokusebenza iqulethe imingxuma. Ukuba iqonga lebhastile linemingxuma emincinane kumphezulu walo, kufuneka libuyiselwe kumzi-mveliso ukuze lilungiswe. Ukuba ukuchaneka kutshintshile kuphela, ukulungiswa kufuneka kwenziwe kwindawo yokusetyenziswa. Emva kwexesha elide, ukusetyenziswa rhoqo, iqonga lebhastile liya kuthi Ukuba iqonga lebhastile lisicaba kakhulu, impazamo yokuchaneka iya kwanda ngokuthe ngcembe, ibangele ukuchaneka okungachanekanga. Kule meko, ifuna ukulungiswa.
Amanyathelo okulungisa amaqonga ebhastile:
1. Jonga ukuchaneka kweqonga lebhastile kwaye uqinisekise impazamo yalo yangoku.
2. Ukugaya iqonga lemarble ngokurhabaxa usebenzisa abrasives kunye nezixhobo zokusila ukufikelela kwinqanaba elifunekayo.
3. Isiqingatha sesibini sokusila seqonga lebhastile emva kokusila ngokurhabaxa kukususa imikrwelo enzulu kunye nokufikelela kwinqanaba elifunekayo.
4. Gcoba indawo yokusebenza yeqonga lemabhile ukufezekisa ukuchaneka okufunekayo.
5. Vavanya ukuchaneka kweqonga lebhastile emva kokupholisha, kwaye kwakhona emva kwethuba lexesha.
