Ibara rya granite n'amabara y'amabuye yo gukoresha mu bikoresho by'inganda.

Mu bijyanye n'ubwubatsi n'inganda, granite ikoreshwa cyane bitewe n'ubukana bwayo, ubucucike bwayo, ubudahangarwa bwayo na aside na alkali, ndetse no kudahangarwa kwayo n'ikirere. Ibi bikurikira ni isesengura rirambuye kuri wewe ku bijyanye no kumenya niba ibara rya granite rigira ingaruka ku bucucike bwayo n'uburyo bwo guhitamo granite ihamye kurushaho mu bijyanye n'ibikoresho by'inganda bigezweho.
Isano iri hagati y'ibara n'ubucucike bwa granite
Granite igizwe ahanini n'amabuye y'agaciro nka quartz, feldspar na mica, kandi ibara ryayo riterwa n'ubwoko n'ingano y'ibiyigize. Ukurikije ubwinshi bw'ibintu, hari isano iri hagati y'ibara n'ubwinshi bw'ibintu, ariko si isano itaziguye iterwa n'impamvu.

 

Itandukaniro ry'imiterere y'amabuye y'agaciro: Ibara ryorohejeranite, nk'umweru wijimye n'umutuku utukura, akenshi ikungahaye kuri quartz na feldspar. Izi myunyu ngugu zombi zifite ubucucike buri hejuru kandi buhamye. Ubucucike bwa quartz buri hagati ya 2.6 na 2.7g/cm³, mu gihe ubwa feldspar buhinduka hagati ya 2.5 na 2.8g/cm³ bitewe n'ubwoko. Ubwinshi bw'izo myunyu ngugu butuma ubucucike rusange bwa granite y'amabara yoroheje buzamuka. Granite yijimye, nk'umukara n'icyatsi kibisi, akenshi iba irimo ingano nyinshi y'ubutare na manyeziyumu ndetse n'ubucucike bwijimye nka amphibole na biotite. Ubucucike bwa amphibole buri hagati ya 3.0-3.4g /cm³, naho ubwa biotite buri hagati ya 2.7-3.1g /cm³. Ariko, iyo granite yijimye irimo ibintu byinshi by'icyuma (nk'icyuma na manganese), ubucucike bwayo burazamuka.

 

Ingano y’ubucukuzi bw’amabuye n’ingaruka ku miterere: Hari igihe ibara rishobora kugaragaza itandukaniro mu rugero rw’ubucukuzi bw’amabuye n’imiterere ya granite. Granite ifite ubucukuzi bwinshi n’imiterere ikomeye ifite ibara ringana kandi rihamye, kandi ubucucike bwayo nabwo buri hejuru. Ibi biterwa nuko uduce tw’imyunyu ngugu tuba dutondekanye neza kandi dufite uburemere bunini kuri buri gipimo. Granite ifite ubucukuzi bubi n’imiterere idakomeye ishobora kugira amabara adahuye kandi adahuye, imyanda myinshi y’imbere, n’ubucucike buke.
Guhitamo granite mu bijyanye n'ibikoresho by'inganda bigezweho
Mu bijyanye n'ibikoresho by'inganda bigezweho, ibisabwa ku buryo butajegajega bya granite biba biri hejuru cyane. Ubusanzwe, granite ikwiye itoranywa hashingiwe ku bintu byinshi:

Imiterere n'imiterere y'amabuye y'agaciro: Granite ifite imiterere myinshi kandi ikwirakwira kimwe muri quartz na feldspar ni yo ikundwa. Ubu bwoko bwa granite bufite imiterere ihamye y'imbere, ishobora kugabanya neza impinduka mu mihindagurikire y'imbere no kwemeza imikorere ihamye y'ibikoresho igihe kirekire. Hagati aho, granite ifite urwego rwo hejuru rwa crystallization, utuntu duto n'utworoshye, hamwe n'imiterere ikomeye ni yo ikundwa. Mu gihe cyo gukoreshwa igihe kirekire no gukoreshwa imbaraga, ishobora gukomeza neza imiterere yayo no kugabanya ingaruka z'impinduka mu miterere yayo ku mikorere y'ibikoresho.

Ibipimo by'imikorere: Granite isabwa kugira igipimo gito cyo kwinjiza amazi, muri rusange kiri munsi ya 0.5%, kugira ngo hirindwe ibibazo nko kwaguka k'ingano no kugabanuka kw'imbaraga biterwa no kwinjiza amazi, bishobora kugira ingaruka ku buryo ibikoresho bikoresha neza. Igipimo cyo kwaguka k'ubushyuhe kigomba kuba gito. Byiza, igomba kuba iri munsi ya 8 × 10⁻⁶/℃ kugira ngo igabanye impinduka ziterwa n'ihindagurika ry'ubushyuhe. Byongeye kandi, imbaraga zo gukanda zigomba kuba nyinshi, muri rusange zirenze 150MPa, kugira ngo ishobore kwihanganira imbaraga zitandukanye mu gihe cy'imikorere y'ibikoresho.
Ubwoko busanzwe busabwa: Jinan Green Granite, Indian Black, South Africa Black n'izindi granite z'umukara, ahanini zifite ibara ryijimye, imiterere yazo ikungahaye, zifite ubushobozi buke bwo kwaguka kw'ubushyuhe kandi zidashobora kwangirika neza, kandi zikwiriye ibikoresho byo kugenzura ikoranabuhanga bifite ibisabwa byinshi kugira ngo bibe byiza kandi bihamye. Granite yera ya Sesame, ifite ibara ryoroheje, utuntu tw'ubutare bumwe, kandi ifite ubukana n'imbaraga nyinshi, ikoreshwa cyane mu bikoresho byo gukora chips z'ikoranabuhanga kandi ishobora guhaza ibisabwa kugira ngo ibikoresho bishyirwe mu buryo bunoze kandi bikore neza igihe kirekire.

Mu gusoza, nubwo hari isano iri hagati y’ibara n’ubucucike bwa granite, mu gihe uhitamo granite mu bijyanye n’ibikoresho by’inganda bigezweho, ni ngombwa gusuzuma mu buryo burambuye ibintu byinshi nko mu miterere y’amabuye y’agaciro, imiterere, n’imiterere ifatika kugira ngo umenye neza ko ibikoresho bifite ubuziranenge n’ubudahangarwa.
