Siyini isisekelo se-granite semishini yokucubungula izithombe?

Isisekelo se-granite siyingxenye ebalulekile yemishini yokucubungula izithombe.Indawo eyisicaba eyenziwe ngegwadle yekhwalithi ephezulu esebenza njengenkundla ezinzile futhi ehlala isikhathi eside yezinto zokusebenza.Izisekelo ze-granite zidume kakhulu ezinhlelweni zokusebenza zokucubungula izithombe zezinga lezimboni lapho ukuzinza, ukunemba, nokunemba kubaluleke kakhulu.

I-Granite iyinto efanelekile ukuthi isetshenziswe ekucubunguleni izithombe ngoba ihlala isikhathi eside kakhulu futhi imelana nokuhlukahluka kwezinga lokushisa nezinye izici zemvelo.Itshe libuye liminyene kakhulu, okusho ukuthi line-coefficient ephansi ye-thermal expansion (CTE).Lesi sici siqinisekisa ukuthi isisekelo se-granite asikhuli noma asifinyeleli ngokushintsha kwezinga lokushisa, kunciphisa ubungozi bokuhlanekezelwa kwesithombe.

Ngaphezu kwalokho, indawo eyisicaba yesisekelo se-granite iqeda noma yikuphi ukudlidliza okungenzeka, iqinisekise ukucutshungulwa kwesithombe okunembile nokunembayo.Ukuminyana okuphezulu kwe-granite nakho kuyenza ibe into efanelekile yezinhlelo zokusebenza zokudambisa umsindo, okuqhubeka kube negalelo ekucutshungulweni okunembayo nokunemba kwedatha yesithombe.

Ekucutshungulweni kwezithombe, ukunemba kwezinto zokusebenza kuyisici esibalulekile.Noma yikuphi ukungafani noma amaphutha ekucubunguleni kungaholela emiphumeleni engalungile kanye nokuhlaziywa okungalungile.Ukuzinza okunikezwa isisekelo se-granite kuqinisekisa ukuthi okokusebenza kuhlala kusendaweni ngaphandle kokunyakaza, okuvumela imiphumela enembe kakhulu.

Kuyaphawuleka ukuthi izisekelo ze-granite azisetshenziswa kuphela kumishini yokucubungula isithombe sezinga lezimboni, kodwa futhi nasezinsizeni zelebhu eziphezulu ezifana nama-microscopes, lapho ukuzinza nokunemba kubaluleke kakhulu.

Kafushane, isisekelo se-granite sisebenza njengesisekelo esibalulekile sezisetshenziswa zokucubungula izithombe, ukuletha ukuzinza, ukunemba, nokunemba ukuze uthole imiphumela enembayo nenembile.Idizayini nokwakhiwa kwayo kuklanyelwe ukunikeza ukudlidliza okuncane kanye nokubekezelela izinga lokushisa okwandisiwe noma okunenkontileka, okudala indawo ezinzile nevikelekile yokucubungula isithombe.Ezimbonini ezinamazinga aqinile okusebenza kahle nokunemba, kuyingxenye ethembekile nedingekayo ukuze kuqinisekiswe impumelelo ekucutshungulweni kwezithombe.
