Iitafile zeGranite zisetyenziswe ngokubanzi kwizixhobo zendibano ezichanekileyo kwaye zithandwa ngenxa yokuzinza kwazo okugqwesileyo kunye nokuchaneka okuphezulu.Itheyibhile yegranite yenziwe nge-granite yendalo, enezinga eliphezulu lobunzima, ukuxhatshazwa okugqwesileyo kokugqoka, kunye nokuzinza okuphezulu, okwenza kube yinto efanelekileyo yezixhobo zokuhlanganisa ngokuchanekileyo.Nangona kunjalo, njengayo nayiphi na imathiriyeli yobunjineli, iitafile zegranite nazo zineziphene ezithile ezichaphazela ukusebenza kwazo.
Esinye seziphene ezinkulu zetafile yegranite kukuvakalelwa kwayo kutshintsho lobushushu.Itheyibhile yegranite ine-coefficient ephezulu yokwandiswa kwe-thermal, oku kuthetha ukuba iyanda okanye inkontileka xa ibonakaliswe kwiinguqu zeqondo lokushisa.Ukutshintsha kobushushu kunokubangela ukuthambeka kwe-thermal kuyo yonke itafile yegranite, enokukhokelela kwi-deformation, ebangela ukungazinzi kwinkqubo yokudibanisa echanekileyo.Esi siphene yinkxalabo enkulu kubavelisi, ngakumbi abo babandakanyekayo kumatshini ochanekileyo.
Esinye isiphene setafile yegranite kukukwazi ukufunxa amanzi.I-Granite yimpahla ye-porous, kwaye amanzi angakwazi ukungena kwitafile ye-granite, ebangela ukuba idumbe kwaye inkontileka, ekhokelela ekuguqulweni kunye nokungazinzi.Abavelisi kufuneka bathathe amanyathelo okuthintela ukufuma ekungeneni kwitafile yegranite, njengokutywina umphezulu wetafile okanye ukusebenzisa indawo elawulwa ngumswakama.
Umphezulu othe tyaba wetafile yegranite nayo iyabaxhalabisa abavelisi.Nangona iitafile zegranite zinezinga eliphezulu lokucaba, azifezekanga, kwaye ukucaba kwazo kunokwahluka ngokuhamba kwexesha.I-flatness yendawo yetafile yegranite inokuchaphazeleka ngokusingqongileyo, umthwalo, kunye nezinye izinto.Ukugcina i-flatness yomhlaba wetafile yegranite, abavelisi kufuneka bahlale begcina kwaye balinganise itafile ukuqinisekisa ukusebenza okuphezulu.
Iitafile zeGranite nazo zisengozini yokulimala ngenxa yeqondo eliphezulu lobunzima.Imiphetho yetafile yegranite inokuthi ikhutshwe ngokulula okanye iqhekezwe ngenxa yoxinzelelo olugqithisileyo ngexesha lofakelo okanye ukusetyenziswa.Nokuba ii-chips ezincinci okanye ii-cracks zinokubangela ukungazinzi kwinkqubo yokudibanisa echanekileyo kwaye ichaphazele ukusebenza kwemveliso.Ukuthintela umonakalo kwitafile yegranite, abavelisi kufuneka bawuphathe ngokucophelela kwaye bagweme uxinzelelo olugqithiseleyo ngexesha lofakelo okanye ukusetyenziswa.
Ukuqukumbela, itafile yegranite yimathiriyeli egqwesileyo yezixhobo zokuhlanganisa ezichanekileyo, kodwa ineziphene zayo.Nangona ezi ziphene, abavelisi banokuthatha amanyathelo okuqinisekisa ukuba itafile yegranite isebenza ngokusemandleni.Ngokugcina kunye nokulinganisa itafile, ukulawula indawo, kunye nokusingatha ngokunyamekela, abavelisi banokunciphisa impembelelo yeziphene kwaye baqinisekise ukuba izixhobo zabo zokuhlanganisa ezichanekileyo ziphezulu kakhulu.
