Iiparamitha zobugcisa kunye neenkcukacha zegranite slabs.

 

I-Granite slabs lukhetho oludumileyo kulwakhiwo kunye noyilo lwangaphakathi ngenxa yokuqina, ukubukeka kobuhle, kunye nokuguquguquka. Ukuqonda iiparitha zobugcisa kunye neenkcukacha ze-granite slabs ziyimfuneko kubakhi bezakhiwo, abakhi, kunye nabaninikhaya ngokufanayo ukwenza izigqibo ezinolwazi.

1. Ukubunjwa kunye noKwakha:
I-Granite lilitye elivuthayo elihlanganiswe ne-quartz, i-feldspar, kunye ne-mica. Ukwakhiwa kweeminerali kuchaphazela umbala we-slab, ukuthungwa, kunye nokubonakala ngokubanzi. Umndilili woxinaniso lwamatye egranite asuka kwi-2.63 ukuya kwi-2.75 g/cm³, nto leyo ebenza bomelele kwaye balungele usetyenziso olwahlukeneyo.

2. Ukutyeba kunye nobukhulu:
Amacwecwe egranite akholisa ukuza ngobukhulu obuyi-2 cm (3/4 intshi) kunye ne-3 cm (1 1/4 intshi). Ubukhulu obuqhelekileyo buyahluka, kodwa imilinganiselo eqhelekileyo iquka i-120 x 240 cm (4 x 8 iinyawo) kunye ne-150 x 300 cm (5 x 10 iinyawo). Ubukhulu obuqhelekileyo bukwakhona, buvumela ukuguquguquka kuyilo.

3. Ukugqitywa komphezulu:
Ukugqitywa kwee-slabs zegranite kunokuchaphazela kakhulu inkangeleko kunye nokusebenza kwazo. Iziqendu eziqhelekileyo ziquka ukugudiswa, ukuhonjiswa, ukuvutha, kunye nebrashi. Ukugqiba okukhazimlisiweyo kunika inkangeleko ekhazimlayo, ngelixa i-honed ibonelela ngomphezulu we-matte. Ukugqitywa okuvuthayo kukulungele usetyenziso lwangaphandle ngenxa yeempawu zabo zokungatyibiliki.

4. Ukufunxwa kwamanzi kunye nePorosity:
Izitye zegranite zinezinga eliphantsi lokufunxa amanzi, ngokuqhelekileyo malunga ne-0.1% ukuya kwi-0.5%. Olu phawu lubenza baxhathise ukungcolisa kwaye bafaneleke kwii-countertops zasekhitshini kunye nezindlu zangasese. I-porosity ye-granite inokuhluka, ichaphazela iimfuno zayo zokugcinwa.

5. Ukomelela kunye noKuhlala ixesha elide:
IGranite iyaziwa ngamandla ayo akhethekileyo, inamandla oxinzelelo ukusuka kwi-100 ukuya kwi-300 MPa. Oku kuqina kwenza kube lukhetho olufanelekileyo kwiindawo eziphezulu zezithuthi kunye nezicelo zangaphandle, ukuqinisekisa ixesha elide kunye nokuchasana nokunxiba.

Ukuqukumbela, ukuqonda iiparamitha zobugcisa kunye neenkcukacha zamatye egranite kubalulekile ekukhetheni imathiriyeli efanelekileyo kuyo nayiphi na iprojekthi. Ngeepropati zabo ezizodwa, ii-slabs ze-granite ziqhubeka zikhethwa ngokukhethekileyo kwiindawo zokuhlala kunye nezorhwebo.
