Ipulatifomu yegranite iyipulatifomu eyenziwe ngegranite. Yakhiwe ngedwala eliyi-igneous, igranite iyitshe eliqinile, eliyikristalu. Ekuqaleni yayakhiwe nge-feldspar, i-quartz, negranite, ihlanganiswe neminerali eyodwa noma ngaphezulu emnyama, yonke ihlelwe ngendlela efanayo.
I-granite yakhiwe ngokuyinhloko yi-quartz, i-feldspar, kanye ne-mica. I-Feldspar ingama-40%-60%, kanti i-quartz ingama-20%-40%. Umbala wayo uncike ohlotsheni kanye nenani lalezi zingxenye. I-granite iyidwala elicwebezelayo ngokuphelele. I-granite esezingeni eliphezulu inezinhlamvu ezincane nezifanayo, isakhiwo esiminyene, okuqukethwe yi-quartz ephezulu, kanye nokukhanya okukhanyayo kwe-feldspar.
I-Granite inokuqukethwe okuphezulu kwe-silica, okwenza ibe yidwala elinobuthi. Amanye ama-granite aqukethe inani elincane lezinto ezinemisebe, ngakho-ke lezi zinhlobo ze-granite kufanele zigwenywe ukusetshenziswa endlini. I-Granite inesakhiwo esiqinile, ukuthungwa okuqinile, futhi imelana nama-acid, ama-alkali, kanye nokuguquguquka kwesimo sezulu, okwenza ifaneleke ukusetshenziswa ngaphandle isikhathi eside. I-Granite inezici ezilandelayo:
1. I-Granite inesakhiwo esiminyene, amandla aphezulu okucindezela, ukumuncwa kwamanzi aphansi, ubulukhuni obuphezulu bendawo, ukuzinza okuhle kwamakhemikhali, kanye nokuqina okuqinile, kodwa ukumelana nomlilo okubi.
2. I-Granite inesakhiwo esinama-granular esinohlamvu oluncane, oluphakathi, noma oluqinile, noma isakhiwo se-porphyritic. Izinhlamvu zayo ziyafana futhi zincane, zinezikhala ezincane (ama-porosity ngokuvamile angu-0.3% kuya ku-0.7%), ukumuncwa kwamanzi okuphansi (ngokuvamile ngu-0.15% kuya ku-0.46%), kanye nokumelana okuhle nesithwathwa.
3. I-granite iqinile, inobunzima be-Mohs obungaba ngu-6 kanye nobuningi obusukela ku-2.63 g/cm³ kuya ku-2.75 Ububanzi be-g/(cm³) bunamandla okucindezela angu-100-300 MPa, kanti i-granite ecolekile ifinyelela ngaphezu kwe-300 MPa. Amandla ayo okugobeka ngokuvamile aphakathi kwe-10 ne-30 MPa.
Okwesine, i-granite inezinga eliphezulu lokuvunwa, iyakwazi ukusebenzisa izindlela ezahlukene zokucubungula, futhi inezakhiwo ezinhle kakhulu zokuhlanganisa ama-slab. Ngaphezu kwalokho, i-granite ayilula ukuyilungisa, okwenza ifanelekele izinjongo zokuhlobisa zangaphandle.
Ukugcina ipulatifomu yemabula (i-marble slab) kudinga ukunquma ukubekezelelana nezidingo zokugcinwa kwepulatifomu yemabula yamanje, kanye nokunquma ukuthi indawo yokusebenza inemigodi yini. Uma ipulatifomu yemabula inemigodi emincane ebusweni bayo, kufanele ibuyiselwe efektri ukuze icutshungulwe. Uma ukunemba kushintshile kuphela, ukulungiswa kufanele kwenziwe endaweni esetshenziswayo. Ngemva kokusetshenziswa isikhathi eside, njalo, ipulatifomu yemabula izosebenza Uma ipulatifomu yemabula ithambe kakhulu, iphutha lokunemba lizokhula kancane kancane, okuholela ekunembileni okungalungile. Kulokhu, kudinga ukulungiswa.
Izinyathelo zokulungisa amapulatifomu e-marble:
1. Hlola ukunemba kwepulatifomu yemabula bese uthola iphutha layo lamanje.
2. Gaya ipulatifomu yemabula ngendlela ehlelekile usebenzisa izinto zokukhuhla namathuluzi okugaya ukuze ufinyelele izinga elidingekayo.
3. Ukugaya kwesibili okuyingxenye encane kwepulatifomu yemabula ngemva kokugaya okuqinile ukususa imihuzuko ejulile nokufinyelela izinga elidingekayo.
4. Gaya indawo yokusebenza yesikhulumi semabula ukuze kufezwe ukunemba okudingekayo.
5. Hlola ukunemba kwepulatifomu yemabula ngemva kokupholisha, futhi futhi ngemva kwesikhathi esithile.
