Kwicandelo lokuvelisa izinto ezikumgangatho ophezulu, iqonga le-XYZ elichanekileyo lineemfuno ezingqongqo kakhulu zokusebenza kwezixhobo. I-granite yendalo, enoluhlu lweempawu ezibalaseleyo, iye yaba lukhetho oluphezulu kune-marble.
I. Uthelekiso lweePropati zoMatshini
Ukuqina kunye nokumelana nokuguguleka
I-granite yenziwe kakhulu ziiminerali ezifana ne-quartz kunye ne-feldspar, enobunzima be-Mohs obuyi-6 ukuya kwi-7. Ingamelana ngempumelelo nokuguguleka kwaye igcine ukuchaneka komphezulu weqonga ngexesha lokusetyenziswa ixesha elide kunye nokuhamba rhoqo koomatshini. Ngokwahlukileyo koko, inxalenye ephambili yemabula, i-calcium carbonate, inobunzima obuphantsi, kunye nobunzima be-Mohs obuyi-3 ukuya kwi-5 kuphela. Phantsi kokungqubana okufanayo kunye noxinzelelo, ithambekele ngakumbi ekukrweleni nasekugugulekeni, okuchaphazela ukuchaneka kunye nobomi benkonzo yeqonga.
Ukuqina kunye nozinzo
I-Granite inesakhiwo esixineneyo, kunye namasuntswana eeminerali angaphakathi adibana ngokusondeleyo, okwenza ukuba ibe nokuqina okugqwesileyo. Xa ithwalwa yimithwalo enzima kunye noxinzelelo loomatshini, inokugcina uzinzo lwesakhiwo kwaye ayiguquguquki. Nangona kunjalo, imabula inenani elikhulu leetextures kunye nee-cracks ezincinci ngaphakathi, kwaye ukuqina kwayo kubuthathaka. Ngexesha lemithwalo ephezulu okanye ukusetyenziswa ixesha elide, inokuba nee-cracks okanye ii-deformations ngenxa yoxinzelelo, okuchaphazela ukuzinza kunye nokuchaneka kweqonga.
Ii. Umahluko ekusebenzeni kobushushu
I-coefficient yokwandiswa kobushushu
I-Granite inomlinganiselo ophantsi kakhulu wokwandiswa kobushushu, malunga ne-4-8×10⁻⁶/℃, kwaye ubungakanani bayo buyatshintsha kancinci xa ubushushu butshintsha. Oku kubalulekile kwiiplatifomu ze-gantry ze-XYZ ezichanekileyo kakhulu, ezinokuthintela ukuguqulwa kobushushu okubangelwa kukuguquguquka kobushushu kwaye ziqinisekise ukuba ukuchaneka kwendawo yeplatifomu akuchaphazeleki. Umlinganiselo wokwandiswa kobushushu bemabula uphezulu. Kwimeko enotshintsho olukhulu lobushushu, ithambekele ekukhuleni nasekuncipheni kobushushu, okunokubangela utshintsho kubukhulu nasekuchanekeni kweplatifomu.
Ukuqhuba kobushushu
Igranite inomoya ophantsi wokushisa. Xa ifudunyezwa kwindawo ethile, ubushushu buyasasazeka kancinci, nto leyo enokunciphisa ukwenzeka kokuguquka kobushushu. Imarble inomoya ophakamileyo wokushisa. Kwiimeko zokusetyenziswa ezifana nokucubungula nge-laser okuvelisa ubushushu obuninzi, ubushushu bunokwenzeka ukuba buqhutywe kwaye busasazeke, nto leyo ebangela ukuguquguquka kobushushu obungalinganiyo kweqonga kwaye ichaphazele ukuchaneka kokucubungula.
Iii. Umahluko kwiimpawu zokudambisa
I-Granite ineempawu ezintle zokudambisa, kwaye isakhiwo sayo sangaphakathi sinokufunxa ngempumelelo kwaye sinciphise amandla okudambisa. Ngexesha lokusebenza kweqonga le-gantry, ukudambisa kunokuncitshiswa ngokukhawuleza, kunciphisa impembelelo yokudambisa ekuchanekeni kokucubungula kunye nobomi bezixhobo. Ukusebenza kokudambisa kwe-marble kubuthathaka, okwenza kube nzima ukunciphisa ngokukhawuleza ukudambisa okufana ne-granite, okungahambelaniyo nemisebenzi yokucubungula ngokuchanekileyo.
Iv. Izinto ekufuneka ziqwalaselwe xa kuziwa ekuzinzeni kweekhemikhali
I-granite inamandla okuqina kweekhemikhali kwaye iyamelana nokugqwala kwe-asidi kunye ne-alkali. Kwezinye iindawo ezikhethekileyo zokucubungula, ezifana nezo zibandakanya ii-reagents zeekhemikhali okanye iigesi ezigqwalisayo, amaqonga e-granite anokugcina uzinzo lweempawu zezinto kwaye athintele ukugqwala. Icandelo eliphambili le-marble, i-calcium carbonate, lithanda ukusabela kweekhemikhali kunye nee-asidi kwaye ligqwala lula kwiindawo ezine-asidi, nto leyo ekhokelela ekonakaleni komphezulu weqonga kunye nokwehla kokuchaneka.
V. Ubomi beNkonzo kunye neendleko zoLondolozo
Ngenxa yeenzuzo zegranite ngokubhekiselele kubulukhuni, ukumelana nokuguguleka kunye nokuzinza kobushushu, ubomi bayo benkonzo buhlala bude kunebemarble. Ngaphezu koko, igranite ayigugi kakhulu, inokuguquguquka okuncinci, umjikelo omde wokugcinwa, kunye neendleko zokugcinwa eziphantsi. Ngenxa yeengxaki ezifana nokuguguleka okulula kunye nokuzinza kobushushu obuphantsi, imable ifuna ukulinganiswa rhoqo, ukulungiswa kunye nokutshintshwa, okubangela iindleko eziphezulu zokugcinwa.
Ukuqukumbela, igranite yendalo idlula imabula kwiinkalo ezininzi ezifana neempawu zoomatshini, iimpawu zobushushu, iimpawu zokudambisa, uzinzo lweekhemikhali, ubomi benkonzo kunye neendleko zokugcinwa. Ke ngoko, iye yaba yeyona nto ifanelekileyo kwiiplatifomu ze-gantry ezichanekileyo ze-XYZ.
