Muminda yekuvaka uye indasitiri, granite inoshandiswa zvakanyanya nekuda kwekuoma kwayo, density, acid uye alkali kuramba, uye kusagadzikana kwemamiriro ekunze. Iyi inotevera ongororo yakadzama kwauri pamusoro pekuti ruvara rwegranite runokanganisa kusimba kwayo uye kuti ungasarudza sei yakagadzikana giraniti mumunda wezvigadzirwa zvemaindasitiri.
Ukama huri pakati peruvara uye density yegranite
Granite inonyanya kuumbwa nemaminerari akadai sequartz, feldspar uye mica, uye ruvara rwayo rwunoenderana nemhando uye huwandu hwezvikamu zvauri. Kubva pakuona kwehuwandu, pane imwe hukama pakati pevara uye density, asi haisi hukama hwakananga hunokonzera.
Mineral composition musiyano: Chiedza-ruvara granite, yakadai segreyish-white uye nyama-tsvuku, inowanzopfuma mu quartz uye feldspar. Aya maminerari maviri ane huwandu hwakanyanya uye hwakagadzikana. Kuwanda kwequartz kunotangira pa2.6 kusvika 2.7g/cm³, nepo feldspar inosiyana kubva pa2.5 kusvika 2.8g/cm³ zvichienderana nerudzi. Kuwanda kwemaminerari akadaro kunotungamirira kune kukwira kumusoro muhuwandu hwehuwandu hwegranite ine ruvara rwakajeka. Giraniti yakasviba, yakadai seyakasviba uye yakasvibirira, inowanzo ine yakawanda yakawanda yesimbi uye magnesium zvicherwa pamwe chete nemaminerari erima seamphibole uye biotite. Kuwanda kweamphibole inenge 3.0-3.4g /cm³, uye iyo yebiotite inenge 2.7-3.1g /cm³. Zvisinei, kana granite yakasviba iine zvimwe zvinorema simbi zvinhu (zvakadai sesimbi uye manganese), kuwanda kwayo kuchawedzera.
Dhigirii rekristallisation uye chimiro chesimba: Ruvara runogona dzimwe nguva kuratidza mutsauko muchiyero chekristaro uye chimiro chegranite. Granite ine hupamhi hwekristaro uye dense chimiro chine yunifomu uye yakagadzikana ruvara, uye density yayo zvakare yakakwira. Izvi zvinodaro nekuti mamineral particles akanyatsorongeka uye ane huwandu hukuru pavhoriyamu yeyuniti. Granite ine crystallization isina kusimba uye yakasununguka chimiro inogona kunge iine mavara uye asina kuenzana mavara, akawanda emukati ma voids, uye yakaderera density.
Granite kusarudzwa mumunda wezvigadzirwa zvemaindasitiri
Mumunda wezvigadzirwa zvemaindasitiri, izvo zvinodikanwa zvekugadzikana zvegranite zvakakwirira zvakanyanya. Kazhinji, iyo granite yakakodzera inosarudzwa nekunyatso funga zvinhu zvakawanda:
Mineral kuumbwa uye chimiro: Granite ine yakakwirira yehuwandu uye yunifomu kugovera kwequartz uye feldspar inosarudzwa. Rudzi urwu rwegranite rune chimiro chemukati chakagadzikana, chinogona kunyatso kuderedza deformation inokonzerwa nekuchinja kwekushungurudzika kwemukati uye kuvimbisa kushanda kwakasimba kwenguva refu kwemichina. Zvichakadaro, granite ine yakakwira dhigirii recrystallization, yakanaka uye yunifomu zvimedu, uye dense chimiro ndicho chinosarudzwa sarudzo. Munguva yekushandiswa kwenguva refu uye kushandiswa kwekumanikidza, inogona kuchengetedza zvirinani uye kuderedza kukanganiswa kweiyo yega shanduko yezvimiro pakurongeka kwemidziyo.
Zviratidzo zvekushanda kwemuviri: Granite inodiwa kuti ive nehuwandu hwekunyura kwemvura, kazhinji isingasviki 0.5%, kudzivirira matambudziko akadai sekuwedzera kwehuwandu uye kuderedzwa kwesimba kunokonzerwa nekunyura kwemvura, izvo zvinogona kukanganisa kurongeka kwemidziyo. Iyo coefficient yekuwedzera kwekushisa inofanira kuva yakaderera. Zvakanaka, inofanira kunge iri pasi pe8 × 10⁻⁶/℃ kuderedza shanduko ye dimensional inokonzerwa nekusiyana kwekushisa. Pamusoro pezvo, simba rekumanikidza rinofanira kunge rakakwira, kazhinji rakakura kupfuura 150MPa, kuve nechokwadi kuti rinogona kumirisana nemasimba akasiyana panguva yekushanda kwemidziyo.
Mhando dzakajairwa dzinokurudzirwa: Jinan Green Granite, Indian Black, South Africa Nhema uye imwe nhema yegranite, iyo yakanyanya kusviba muruvara, yakaonda muchimiro, ine yakaderera coefficient yekuwedzera kwemafuta uye yakanaka kupfeka kuramba, uye akakodzera kune zvigadziko zve optical yekuongorora michina ine zvakanyanyisa zvinodiwa zvekunyatso uye kugadzikana. Sesame chena granite, ine ruvara rwakareruka, yunifomu yemaminerari zvimedu, uye kuomarara kwakanyanya uye simba, inoshandiswa zvakanyanya mumagetsi chip kugadzira michina uye inogona kuzadzisa zvinodiwa zvepamusoro-chaiyo chinzvimbo uye kwenguva yakareba yakagadzikana kushanda kwemidziyo.
Mukupedzisa, kunyangwe paine kumwe kuwirirana pakati peruvara uye kuwanda kwegranite, pakusarudza granite mumunda wezvigadzirwa zvemaindasitiri, zvinofanirwa kunyatso tarisa zvinhu zvakawanda senge mineral kuumbwa, chimiro, uye zvimiro zvemuviri kuti ive nechokwadi chepamusoro uye kugadzikana kwemidziyo.
