I-Granite, njengesixhobo esisetyenziswa kakhulu ekwakheni, ekuhombiseni, kwiziseko zezixhobo ezichanekileyo nakwezinye iindawo, uxinano lwayo luphawu olubalulekileyo lokulinganisa umgangatho kunye nokusebenza. Xa ukhetha izinto ze-granite, kubalulekile ukuqonda izinto eziphambili ezichaphazela uxinano lwazo. Oku kulandelayo kuza kukuchazela ngokweenkcukacha.
I. Ukwakheka kwezimbiwa
I-granite yenziwe kakhulu ziiminerali ezifana ne-quartz, i-feldspar kunye ne-mica. Ulwakhiwo lwekristale, umxholo kunye nohlobo lwezi minerali zonke zinempembelelo enkulu kuxinano. Izakhiwo zekristale ze-quartz kunye ne-feldspar zincinci kakhulu, kwaye uxinano lwazo luphezulu kakhulu. Xa umxholo wezi minerali zimbini kwi-granite uphezulu, uxinano lulonke luya kwanda ngokufanelekileyo. Umzekelo, ezinye iintlobo zegranite ezityebileyo kwi-quartz kunye ne-feldspar zihlala zinoxinano oluphezulu. Ngokwahlukileyo koko, ulwakhiwo lwekristale lwe-mica lukhululekile. Ukuba umxholo we-mica kwi-granite uphezulu kakhulu, kuya kukhokelela ekunciphiseni uxinano lwazo. Ukongeza, i-granite equlethe iiminerali ezininzi ezinobunzima beemolekyuli eziphezulu ezifana ne-iron kunye ne-magnesium idla ngokuba noxinano oluphezulu. I-granite, etyebileyo kwiiminerali ze-silicate, inoxinano oluphantsi kakhulu.
Ii. Ubungakanani kunye nolwakhiwo lwamaqhekeza
Ubungakanani besuntswana
Okukhona amasuntswana egranite enciphile, kokukhona eqina, kwaye kokukhona amasuntswana angaphakathi enciphile, nto leyo ekhokelela ekwandeni kobunzima ngeyunithi nganye kunye noxinano oluphezulu. Ngokwahlukileyo koko, kwigranite erhabaxa, amasuntswana kunzima ukuwahlanganisa ngokusondeleyo kwaye kukho amasuntswana amaninzi, nto leyo ebangela ukuba abe noxinano oluphantsi.
Ubungakanani bokuqina kwesakhiwo
Igranite enesakhiwo esincinci inamasuntswana eeminerali adityaniswe ngokusondeleyo nezithuba ezingabonakaliyo. Esi sakhiwo sinceda ekwandiseni uxinano. Nangona kunjalo, igranite eyakhiwe ngokukhululekileyo, ngenxa yokudibana okukhululekileyo phakathi kwamasuntswana, inendawo enkulu kwaye ngokwendalo inoxinano oluphantsi. Umzekelo, igranite enesakhiwo esixineneyo esenziwe ngeenkqubo ezikhethekileyo zejoloji inoxinano olwahluke kakhulu xa kuthelekiswa nomlingani wayo okhululekileyo.
Iii. Umgangatho wekristali
Ngexesha lokwenziwa kwegranite, njengoko ubushushu kunye noxinzelelo lutshintsha, iikristale zeminerali ziya kunyibilika kancinci kancinci. Igranite enezinga eliphezulu lekristale inolungelelwano oluthe tye noluncinci lwekristale, kwaye izithuba phakathi kweekristale zincinci. Ke ngoko, inobunzima obukhulu ngeyunithi nganye kunye noxinano oluphezulu. Igranite enezinga eliphantsi lekristale inolungelelwano oluthe ngcembe lwekristale kunye nezithuba ezinkulu phakathi kweekristale, nto leyo ebangela ukuba uxinano lube phantsi.
Iimbobo kunye neeNkathazo
Ngexesha lokwenziwa nokumbiwa kwegranite, iimbobo kunye neentanda zinokwenzeka. Ukubakho kwezi mbobo kuthetha ukuba akukho kuzaliswa kwezinto eziqinileyo kule ndawo, okuya kunciphisa ubunzima begranite kwaye ngaloo ndlela kunciphise uxinano lwayo. Okukhona iimbobo kunye neentanda zininzi, kokukhona zinkulu ubukhulu bazo kwaye ukusasazwa kwazo kubanzi, kokukhona isiphumo sokunciphisa uxinano siya kuba sicacile. Ke ngoko, xa ukhetha izinto zegranite, ukujonga ukuba kukho iimbobo kunye neentanda ezibonakalayo kumphezulu wayo kunokusetyenziswa njengento yokubhekisa ekuvavanyeni uxinano lwayo.
V. Ukwakha Okusingqongileyo
Iimeko ezahlukeneyo zejoloji zinokubangela umahluko ekusasazweni nasekuqulathweni kweeminerali kwigranite, ngaloo ndlela zichaphazela uxinano lwayo. Umzekelo, igranite eyenziwe phantsi kweemeko zobushushu obuphezulu kunye noxinzelelo oluphezulu inekristali epheleleyo yeeminerali, isakhiwo esincinci ngakumbi, kunye noxinano olunokuba phezulu. Uxinano lwegranite olwenziwe kwindawo ethambileyo lunokwahluka. Ukongeza, izinto ezingqongileyo ezifana nobushushu, uxinzelelo kunye nokufuma zinokuchaphazela isakhiwo kunye nokwakheka kweeminerali kwigranite, zichaphazela ngokungathanga ngqo uxinano lwayo.
Vi. Iindlela zokuCwangcisa
Iindlela ezisetyenziswa kwinkqubo yokwemba, ezinje ngokumba ngokuqhumisa, zinokubangela imingxunya emincinci ngaphakathi kwegranite, nto leyo echaphazela ukuqina kwesakhiwo sayo kwaye emva koko ibe nefuthe elithile kuxinano lwayo. Ukutyumza, ukugawula kunye nezinye iindlela ngexesha lokucubungula nazo zinokutshintsha imeko yamasuntswana kunye nolwakhiwo lwegranite, ngaloo ndlela zichaphazela uxinano lwayo. Ngexesha lokuthuthwa nokugcinwa kwayo, iindlela ezingafanelekanga zokupakisha okanye iindawo zokugcina ezinzima zinokubangela ukuba igranite icinezelwe, ingqubane okanye ibole, nto leyo enokuchaphazela uxinano lwayo.
Ukuqukumbela, xa ukhetha izinto zegranite, kuyimfuneko ukuqwalasela ngokupheleleyo izinto ezahlukeneyo ezichaphazela uxinano olukhankanyiweyo apha ngasentla ukuze kuvavanywe ngokuchanekileyo ukusebenza kwazo kwaye kukhethwe izinto zegranite ezifanelekileyo kwiimeko ezithile zokusetyenziswa.
