Kwicandelo lokulinganisa ngokuchanekileyo, umatshini wokulinganisa ubude sisixhobo esibalulekileyo sokuqinisekisa ukuchaneka kobukhulu beemveliso, kwaye ukusebenza kwezixhobo zawo ezisisiseko kuchaphazela ngokuthe ngqo uzinzo kunye nobomi benkonzo yezixhobo. Kwiminyaka yakutshanje, inani elandayo loomatshini bokulinganisa ubude liqalise ukusebenzisa i-granite njengesixhobo esisisiseko. Esinye sezizathu ezibalulekileyo zoku ngamandla okudinwa abalaseleyo e-granite. Idatha yovavanyo ibonisa ukuba amandla okudinwa kwezinto ze-granite aphezulu ngokuphindwe kasixhenxe kune-cast iron. Le nzuzo ibalulekileyo inika isiqinisekiso esinamandla sokwandisa ubomi benkonzo yesiseko somatshini wokulinganisa ubude.
Ukuqinisekisa umahluko kumandla okudinwa phakathi kwegranite kunye nesinyithi esityhidiweyo, iqela lophando lenze uthotho lweemvavanyo eziqatha. Olu vavanyo lukhethe iisampulu zegranite kunye neziseko zesinyithi ezityhidiweyo ezineenkcazo ezifanayo kwaye phantsi kweemeko zokulinganisa zeemeko zokusebenza ezifanayo. Ngomatshini wokuvavanya ukudinwa, kusetyenziswa imithwalo etshintsha rhoqo kwiisampulu zesiseko sezinto ezimbini ukulinganisa amandla angaphandle afana nokungcangcazela kunye noxinzelelo olufunyanwa ngumatshini wokulinganisa ubude ngexesha lokusetyenziswa ixesha elide. Ngexesha lovavanyo, utshintsho lwesakhiwo se-microstructure, iimeko zomonakalo womphezulu kunye nomlinganiselo wokonakala kweempawu zoomatshini ze-macroscopic zezixhobo emva komjikelo ngamnye wokulayisha zirekhodwe ngokuchanekileyo.
Emva kwenani elikhulu lovavanyo lwe-loading loop, iziphumo ziyamangalisa. Ukuqhekeka okucacileyo kokudinwa kwavela kwiisampulu zesiseko sesinyithi emva kwenani elincinci lemijikelo yokulayisha. Njengoko inani lemijikelo lisanda, ezi qhekeko ziyaqhubeka nokukhula kwaye zidibana, nto leyo ebangela ukonakala kobume besakhiwo sezinto kunye nokwehla okukhulu kwiimpawu zazo zoomatshini. Nangona kunjalo, iisampulu zesiseko se-granite zaqala ukubonisa iiqhekeko ezincinci kakhulu emva kokuba zidlule kwimijikelo yokulayisha izihlandlo ezininzi kunezesinyithi esityhidiweyo, kwaye isantya sokusasazeka kweeqhekeko sasicotha kakhulu. Ukusuka kwimbono ye-macroscopic, inqanaba lokuwohloka kwepropathi yoomatshini yeziseko ze-granite liphantsi kakhulu kuneleziseko zesinyithi esityhidiweyo. Ngokuhlalutya idatha yobungcali kunye nokubala, ekugqibeleni kwagqitywa kwelokuba amandla okudinwa kwezinto ze-granite aphezulu ngokuphindwe kasixhenxe kunezesinyithi esityhidiweyo.
Isizathu sokuba izinto zegranite zibe namandla aphezulu okudinwa sinxulumene kakhulu nesakhiwo sazo sangaphakathi kunye neempawu zazo zeminerali. Igranite lilitye eliyi-igneous elenziwe ngokudibeneyo kweekristale ezahlukeneyo zeminerali. Amasuntswana eminerali angaphakathi kuyo ayadibana, enza isakhiwo esixineneyo nesizinzileyo. Esi sakhiwo senza igranite ikwazi ukusasaza uxinzelelo ngokulinganayo xa iphantsi kwamandla angaphandle, inciphisa imeko yoxinzelelo lwendawo, ngaloo ndlela ilibazisa ngempumelelo ukuveliswa kunye nokwanda kweentanda zokudinwa. Ngokwahlukileyo koko, kukho ii-pores ezincinci kunye nokungcola ngaphakathi kwesinyithi esityhidiweyo. Ezi ziphene ziba "yindawo yokuzalela" yokuqalisa iintanda zokudinwa. Xa ziphantsi kwamandla angaphandle, zinokubangela uxinzelelo kwaye zikhawulezise ukusilela kokudinwa kwezinto.
Kumatshini wokulinganisa ubude, amandla aphezulu okudinwa kwesiseko segranite athetha ukuba ngexesha lokusetyenziswa ixesha elide, uzinzo kunye nokuchaneka kwesakhiwo kunokugcinwa ngcono. Impazamo yokulinganisa ebangelwe kukuguquka kokudinwa kwesiseko inciphile, kwaye ukuthembeka kweziphumo zokulinganisa kuphuculwe. Okwangoku, njengoko isiseko segranite singachaphazeleki kakhulu kukonakala kokudinwa, kunciphisa kakhulu amaxesha okugcinwa kunye neendleko zokutshintshwa kwezixhobo, kwaye kwandisa kakhulu ubomi benkonzo iyonke yomatshini wokulinganisa ubude.
Kwimeko-bume yokuvelisa yanamhlanje apho iimfuno zokuchaneka kweemveliso ziqina ngakumbi, ukuzinza kokusebenza komatshini wokulinganisa ubude, njengesixhobo esiphambili sokulawula umgangatho, kubaluleke kakhulu. Izinto zegranite, ezinamandla okudinwa adlula kakhulu lawo enziwe ngentsimbi ephosiweyo, zibonelela ngokhetho olungcono loyilo kunye nokuveliswa kwesiseko somatshini wokulinganisa ubude, zibe yimfihlo ebalulekileyo yokwandisa ubomi benkonzo yesiseko somatshini wokulinganisa ubude kunye nokuqinisekisa ukuchaneka komlinganiselo ochanekileyo. Kuya kufuneka idlale indima enkulu ekukhuthazeni uphuhliso lwetekhnoloji yokulinganisa ngokuchanekileyo.
