Granite, sechishandiso chinoshandiswa zvakanyanya mukuvaka, kushongedza, mabhesi emidziyo chaiyo nedzimwe nzvimbo, huwandu hwayo chiratidzo chakakosha chekuyera mhando uye mashandiro. Pakusarudza zvinhu zvegranite, zvakakosha kunzwisisa zvinhu zvikuru zvinokanganisa huwandu hwazvo. Zvinotevera zvichatsanangura zvakadzama nezvazvo.
I. Kuumbwa kweZvicherwa
Granite inonyanya kuumbwa nezvicherwa zvakaita se quartz, feldspar ne mica. Maumbirwo ekristaro, zvirimo uye rudzi rwezvicherwa izvi zvine simba guru pakuwanda kwezvicherwa. Maumbirwo ekristaro e quartz ne feldspar akaomesesa, uye kuwanda kwazvo kwakakwira. Kana zvirimo zvezvicherwa izvi zviviri mu granite zvakakwirira, kuwanda kwese kuchawedzerawo zvinoenderana. Semuenzaniso, mamwe marudzi egranite akapfuma mu quartz ne feldspar anowanzova nekuwanda kwakanyanya. Kusiyana neizvi, maumbirwo ekristaro e mica haana kusimba zvakanyanya. Kana zvirimo zve mica mu granite zvakakwirira, zvichaita kuti kuwanda kwayo kudzikire. Pamusoro pezvo, granite ine zvicherwa zvakawanda zvine huremu hwakawanda hwemamorekuru senge iron ne magnesium inowanzova nekuwanda kwakanyanya. Granite, ine zvicherwa zvakawanda, ine huwandu hwakaderera.
Ii. Kukura kwezvikamu uye Maumbirwo
Saizi yezvimedu
Kana zvidimbu zvegranite zvakatetepa, zvinova zvakamanikana, uye kana zvidimbu zvemukati zvikashoma, zvinoita kuti huwandu hwemaumbirwo huwedzere uye huwandu hwemaumbirwo huwedzere. Kusiyana neizvi, kune granite ine zvidimbu zvakakora, zvidimbu zvakaoma kuunganidzwa pamwe chete uye kune zvidimbu zvakawanda, zvichikonzera kuti zvidimbu zvive zvishoma.
Dhigirii rekusimba kwechimiro
Granite ine chimiro chakamanikana ine zvicherwa zvakabatana zvakanyanya pasina maburi ari pachena. Chimiro ichi chinobatsira kuwedzera huwandu hwezvinhu. Zvisinei, granite yakaumbwa zvisina kusimba, nekuda kwekubatana kwakasununguka pakati pezvikamu, ine nzvimbo yakakura uye ine huwandu hwakaderera. Semuenzaniso, granite ine chimiro chakamanikana chakaumbwa kuburikidza nemaitiro chaiwo e geology ine huwandu hwakasiyana zvakanyanya kana ichienzaniswa neyayo yakaumbwa zvisina kusimba.
III. Dhigirii reKuita Crystallization
Munguva yekuumbwa kwegranite, sezvo tembiricha nekuchinja kwekumanikidzwa zvichichinja, makristaro emaminerari anozonyatsoita makristaro zvishoma nezvishoma. Granite ine kristaro yakawanda ine kurongeka kwakarongeka uye kwakabatana, uye mipata iri pakati pemakristaro midiki. Nokudaro, ine huremu hwakakura pahuwandu hweyuniti uye density yakakwira. Granite ine kristaro yakaderera ine kurongeka kwakashata kwekristaro uye mipata mikuru iri pakati pemakristaro, zvichikonzera density yakaderera.
Maburi neMatsemuka
Panguva yekuumbwa nekucherwa kwegranite, maburi nemaburi zvinogona kuitika. Kuvapo kwemaburi aya kunoreva kuti hapana kuzadza kwakasimba muchikamu ichi, izvo zvinoderedza huremu hwegranite uye nokudaro zvichideredza density yayo. Maburi nemaburi akawanda, kukura kwawo kukuru uye kupararira kwawo kwakafara, ndiko kunonyanya kuoneka kuti density yacho ichaderera. Saka, pakusarudza zvinhu zvegranite, kutarisa kana paine maburi nemaburi ari pachena pamusoro payo kunogona kushandiswa senzira yekutarisa density yayo.
V. Kugadzira Zvakatipoteredza
Mamiriro akasiyana enzvimbo anogona kukonzera kusiyana kwekupararira uye huwandu hwezvicherwa mugranite, zvichikonzera kusimba kwayo. Semuenzaniso, granite inoumbwa pasi pemamiriro ekupisa kwakanyanya uye kusimba kwayo ine mineral crystallization yakakwana, chimiro chakabatana, uye huwandu hunogona kunge hwakakwira. Kusimba kwegranite inoumbwa munzvimbo ine nyoro kunogona kusiyana. Pamusoro pezvo, zvinhu zvakaita sekupisa, kumanikidzwa uye hunyoro zvinogonawo kukanganisa chimiro uye kuumbwa kwemineral yegranite, zvichikanganisa kusimba kwayo zvisina kunanga.
Vi. Nzira dzekugadzirisa
Nzira dzinoshandiswa mukuchera, dzakadai sekuchera gomba, dzinogona kukonzera matombo madiki mukati megranite, zvichikanganisa chimiro chayo uye zvichizokanganisa huwandu hwayo. Kupwanya, kukuya nedzimwe nzira panguva yekugadzirisa zvinogonawo kuchinja mamiriro ezvikamu uye chimiro chegranite, nokudaro zvichikanganisa huwandu hwayo. Munguva yekufambisa nekuchengetedza, nzira dzisina kunaka dzekurongedza kana nzvimbo dzakaoma dzekuchengetedza zvinogona kukonzera kuti granite idzvanyirwe, irove kana kupwanyika, izvo zvinogonawo kukanganisa huwandu hwayo.
Mukupedzisa, pakusarudza zvinhu zvegranite, zvakakosha kufunga zvakadzama nezvezvinhu zvakasiyana-siyana zvinokanganisa kuwanda zvakataurwa pamusoro apa kuti unyatsoongorora mashandiro azvo uye kusarudza zvinhu zvegranite zvakakodzera mamiriro ezvinhu chaiwo ekushandiswa.
