Litekanyetso tsa tekheniki le litekanyetso tsa motheo oa mochini oa granite.

 

Ke khale granite e tsejoa e le thepa ea pele bakeng sa metheo ea mochini ka lebaka la thepa ea eona e ikhethang, ho kenyelletsa le letsoalo le phahameng, ho tiea le ho hanyetsa ho atolosoa ha mocheso. Ho utloisisa litekanyo tsa tekheniki le litekanyetso tse amanang le metheo ea mochini oa granite ho bohlokoa bakeng sa baenjiniere le bahlahisi ba itšetlehileng ka ho nepahala le ho tšoarella lits'ebetsong tsa bona.

E 'ngoe ea likarolo tsa mantlha tsa tekheniki ea metheo ea mochini oa granite ke matla a eona a hatellang, ao hangata a tlohang ho 100 ho isa ho 300 MPa. Matla ana a phahameng a hatellang a tiisa hore granite e khona ho mamella meroalo e meholo ntle le ho senyeha, e etsa hore e be e loketseng ho tšehetsa mechini le lisebelisoa tse boima. Ho feta moo, granite e bonts'a li-coefficients tse tlase tsa katoloso ea mocheso, hangata ho pota 5 ho isa ho 7 x 10 ^ -6 / ° C, e fokotsang liphetoho tsa boholo ka lebaka la ho fetoha ha mocheso, ho netefatsa ts'ebetso e tsitsitseng libakeng tse fapaneng.

Bophahamo ba bokaholimo ke tekanyetso e 'ngoe ea bohlokoa bakeng sa metheo ea mochini oa granite. Mamello ea flatness hangata e hlalosoa ka li-micrometer, tse nang le lisebelisoa tse phahameng tse nepahetseng tse hlokang ho mamellana ka thata joaloka 0.005 mm ka mithara. Boemo bona ba ho nepahala ke ba bohlokoa bakeng sa likopo tse kang ho hokahanya mechine ea ho lekanya (CMMs) le lisebelisoa tsa optical, moo esita le ho kheloha hanyenyane ho ka lebisang liphoso tse kholo tsa tekanyo.

Ho feta moo, boholo ba granite hangata bo fapana ho tloha ho 2.63 ho isa ho 2.75 g/cm³, e leng se tlatsetsang botsitsong ba eona le linthong tse fokotsang ho sisinyeha. Litšobotsi tsena li bohlokoa ho fokotsa tšusumetso ea ho thothomela ha kantle, ka hona, ho ntlafatsa ho nepahala ha lisebelisoa tse hlokolosi tse behiloeng holim'a metheo ea granite.

Qetellong, litekanyo tsa tekheniki le maemo a metheo ea mochini oa granite li bapala karolo ea bohlokoa ts'ebelisong ea tsona liindastering tse fapaneng. Ka ho latela litlhaloso tsena, bahlahisi ba ka netefatsa ho ts'epahala le ts'ebetso ea lisebelisoa tsa bona, qetellong ba lebisa ntlafatsong ea ts'ebetso le ho nepahala lits'ebetsong tsa tlhahiso. Ha theknoloji e ntse e hatela pele, tlhoko ea metheo ea mochini oa granite ea boleng bo holimo e tla tsoela pele ho hola, e totobatsa bohlokoa ba ho utloisisa litekanyetso tsena tsa tekheniki.
