Yini isisekelo se-granite se-appatus yesithombe?

I-Granite Base iyingxenye ebalulekile yezinto zokusebenza zokucubungula isithombe. Kuyindawo eyisicaba eyenziwe kusuka ku-granite esezingeni eliphakeme esebenza njengengxenyekazi ezinzile neqinile yemishini. Izisekelo zeGranite zithandwa kakhulu kwizicelo zokucubungula ezingelona ezimbonini lapho ukuqina, ukunemba, nokunemba kubaluleke kakhulu.

I-Granite iyisitatimende esifanelekile sokusetshenziswa ekucutshungweni kwezithombe ngoba ihlala isikhathi eside kakhulu futhi imelana nokuhluka kwezinga lokushisa kanye nezinye izinto zemvelo. Itshe libuye libe mnene kakhulu, okusho ukuthi linenhlanzeko ephansi yokunwetshwa kwe-thermal (CTE). Lesi sici siqinisekisa ukuthi isisekelo se-granite asikhuli noma sinenkontileka ngezinguquko zokushisa, ukunciphisa ubungozi bokuhlanekezela kwesithombe.

Ngaphezu kwalokho, indawo eyisicaba yesisekelo se-granite isusa noma yikuphi ukudlidliza okungenzeka, kuqinisekise ukucubungula kwesithombe okunembile futhi okuqondile. Ubuningi obuphezulu be-granite bubuye bube yinto efanelekile yezinhlelo zokusebenza ezixhashazwayo zomsindo, efaka isandla ekucutshungweni okunembile futhi okuqondile kwedatha yesithombe.

Ngokucutshungulwa kwezithombe, ukunemba kwemishini kuyisici esibalulekile. Noma yikuphi ukungafani noma amaphutha ekusebenzeni kungaholela emiphumeleni engalungile nokuhlaziywa okungenaphutha. Ukuqina okuhlinzekwa yisisekelo se-granite kuqinisekisa ukuthi imishini ihlala isendaweni ngaphandle kokunyakaza, okuvumela imiphumela eqondile kakhulu.

Kuyaqapheleka ukuthi izisekelo ze-granite azisetshenziswa kuphela kumathuluzi okucubungula izimboni, kodwa futhi nasemishini ye-lab ephezulu enjengemicroscopes, lapho ukuqina nokunemba kubalulekile nje.

Ngamafuphi, isisekelo se-granite sisebenza njengesisekelo esibalulekile sezinhlelo zokusebenza zokucubungula, ukuletha ukuqina, ukunemba, kanye nokunemba kwemiphumela eqondile futhi enembile. Idizayini yayo nokwakha yakhelwe ukunikela ngokudlidliza okuncane nokuvukela kwezinga lokushisa okunwetshiwe noma okwenziwe ngesivumelwano, ukudala indawo ezinzile nephephile yokucutshungulwa kwezithombe. Kwezimboni ezinezindinganiso ezilukhuni zokugqama nokunemba, kuyinto ethembekile futhi edingekayo ukuqinisekisa impumelelo ekusebenzeni kwezithombe.
