Kwicandelo lokuvelisa izinto zoshishino, umatshini wokulinganisa onamakhonkco amathathu (i-CMM) sisixhobo esibalulekileyo sokufezekisa uvavanyo oluchanekileyo kunye novavanyo lokunyamezela imo kunye nendawo, kwaye ukuchaneka kwawo kokulinganisa kuchaphazela ngqo umgangatho wemveliso. Amaqonga okuchaneka kwegranite, ngokusebenza kwawo okugqwesileyo, abe lukhetho olufanelekileyo lwesiseko soomatshini bokulinganisa onamakhonkco amathathu, ebonelela ngeziqinisekiso ezithembekileyo zokufumanisa ngokuchanekileyo okuphezulu.
1. Ukuchaneka okuphezulu kakhulu kunye nozinzo
Amaqonga okuchaneka kwegranite anozinzo oluhle kakhulu kunye ne-coefficient ephantsi kakhulu yokwandiswa kobushushu, eyi-(4-8) ×10⁻⁶/℃ kuphela. Kwindawo yezoshishino enzima neguquguqukayo, nokuba ubushushu buyatshintshatshintsha, utshintsho lobukhulu beqonga alunamsebenzi, nto leyo ethintela ngokufanelekileyo iimpazamo zokulinganisa ezibangelwa kukuguquguquka kobushushu. Okwangoku, ulwakhiwo lwangaphakathi lwekristale yegranite luxinene. Emva kweebhiliyoni zeminyaka yesenzo sejoloji, uxinzelelo lwangaphakathi luye lwasuswa ngokwendalo, kwaye akuyi kubakho ukuguquguquka kokuguga. Oku kuqinisekisa uzinzo lwexesha elide lwesalathiso sokulinganisa kwaye kugcina ukuchaneka kokubeka kunye nokuchaneka kokubeka kwakhona komatshini wokulinganisa odibanisa ezintathu kwinqanaba eliphezulu ngalo lonke ixesha.
Okwesibini, ukusebenza okugqwesileyo kokulwa nokungcangcazela kunye nokunciphisa ubushushu
Ukungcangcazela okubangelwa kukusebenza kwezixhobo zomatshini kunye nokuqala nokuma kwezixhobo kwindawo yokusebenzela yemveliso kunokuphazamisa ukuchaneka kokuchonga komatshini wokulinganisa onama-three-coordinate. I-Granite ineempawu ezibalaseleyo zokudambisa, kunye nomlinganiselo wokudambisa ofikelela kwi-0.05-0.1, onokunciphisa ngokukhawuleza amandla okungcangcazela kwangaphandle. Xa ukungcangcazela kwangaphandle kudluliselwa eqongeni, i-granite inokucinezela ukungcangcazela ngexesha elifutshane, inciphise ukuphazamiseka kokungcangcazela ngexesha lenkqubo yokulinganisa, iqinisekise ukuchaneka koqhagamshelwano phakathi kweprobe yokulinganisa kunye nomphezulu wezinto zokusebenza, kwaye yenze idatha yokulinganisa ichaneke ngakumbi kwaye ithembeke.
Isithathu. Ubulukhuni obuphezulu kunye nokumelana nokuguguleka
I-Granite inobunzima obuyi-6 ukuya kwi-7 kwisikali se-Mohs, ubuninzi obuqala kwi-2.7 ukuya kwi-3.1g/cm³, kunye nokumelana nokuguguleka komphezulu okugqwesileyo. Ngexesha lokusetyenziswa ixesha elide komatshini wokulinganisa onama-three-coordinate, ukulayisha rhoqo kunye nokukhulula izinto zokusebenza kunye nokuhamba kwee-probes zokulinganisa akunakwenzeka ukuba kubangele ukuguguleka kumphezulu weqonga le-granite. Nokuba emva kweminyaka yokusetyenziswa, umphezulu weqonga usenokugcina uthambile kwaye ugudile kakuhle, ukwandisa ngokufanelekileyo ubomi benkonzo echanekileyo yomatshini wokulinganisa onama-three-coordinate kunye nokunciphisa iindleko zokugcinwa kwezixhobo.
Okwesine, uzinzo oluqinileyo lweekhemikhali
Kwiindawo zemveliso yemizi-mveliso, kudla ngokubakho izinto zeekhemikhali ezifana nolwelo lokusika kunye neeoyile zokuthambisa, kwaye ezinye zinokuhamba neegesi ezirhabaxa. I-Granite ineempawu zeekhemikhali ezizinzileyo, uluhlu olubanzi lokunyamezela i-pH (1-14), inokumelana nokukhukuliseka kwezinto eziqhelekileyo zeekhemikhali, kwaye ayichaphazeleki kukugqwala okanye ukugqwala. Olu phawu alukhuseli nje kuphela iqonga ngokwalo kodwa luqinisekisa indawo yokusebenza ecocekileyo yomatshini wokulinganisa odibeneyo kathathu, ukuthintela ukuchaneka kokulinganisa kunye nobomi benkonzo yezixhobo ekuchatshazelweni kungcoliseko lweekhemikhali.
Amaqonga okuchaneka kwegranite, aneenzuzo zokuchaneka okuphezulu, ukuzinza okuphezulu, ukumelana nokungcangcazela, ukumelana nokuguguleka kunye nokuzinza kweekhemikhali, abonelela ngesiseko esiqinileyo sokuchongwa ngokuchanekileyo koomatshini bokulinganisa abathathu kwaye adlala indima engenakutshintshwa kwikhonkco lokulawula umgangatho wemveliso yanamhlanje yokuchaneka.
