Mu rwego rwo gutunganya neza ibikoresho, guhagarara neza no gukora neza ibikoresho ni byo bintu by'ingenzi bigena ubuziranenge bw'ibicuruzwa. Kuva mu gukora ibice ku rwego rwa mikorometero kugeza mu gutunganya neza ibikoresho ku rwego rwa nanometero, ikosa rito rishobora gutuma umusaruro ugabanuka cyangwa se ugasenyuka. Ibicuruzwa bya granite, bifite imiterere igaragara n'ibyiza byabyo bya tekiniki, byabaye urufunguzo rwo kongera guhagarara neza no gukora neza ibikoresho kandi byabaye ikintu cy'ingenzi kandi cy'ingenzi mu nganda zitunganya neza ibikoresho.
Ibyiza byihariye by'imikorere y'ibicuruzwa bya granite
Granite ni ibuye karemano ryakozwe binyuze mu mikorere y’ubutaka mu gihe kirekire. Amabuye y’imbere mu buye ni magufi kandi imiterere yaryo ni minini kandi ingana, bigatuma rigira imiterere ijyanye no gutunganywa neza. Ubwa mbere, granite ifite igipimo gito cyane cy’ubushyuhe, ubusanzwe kiri hagati ya 5 na 7 × 10⁻⁶/℃. Mu gihe cyo gutunganya neza imashini, ubushyuhe buturuka ku mikorere y’ibikoresho no guhinduka k’ubushyuhe bw’ibidukikije ntibibura. Ibikoresho bikozwe mu bikoresho bisanzwe bishobora guhinduka bitewe no kwaguka no guhindagurika k’ubushyuhe, bityo bigira ingaruka ku buryo bwo gutunganya neza. Granite, ku rundi ruhande, ntabwo ihinduka cyane n’impinduka z’ubushyuhe kandi ishobora guhora igumana ingano n’imiterere ihamye, igatanga ishingiro rihamye ry’ibikoresho byo gutunganya neza.
Icya kabiri, ubukana bwinshi n'ubudahangarwa bwiza bwo kwangirika kwa granite bituma ikora neza mu gihe kirekire. Ubukana bwayo bwa Mohs bushobora kugera ku rwego rwa 6 kugeza kuri 7. Iyo ikoreshejwe imbaraga zitandukanye mu gihe cyo gutunganya imashini, ntabwo ikunda kwangirika no guhinduka. Ibi bivuze ko ibikoresho bitunganya neza hakoreshejwe granite bishobora gukomeza gukora neza mu gihe kirekire mu gihe cy'akazi gakomeye, bigagabanya kugabanuka k'ubuziranenge bw'ibikoresho n'inshuro nyinshi z'ikosa riterwa no kwangirika kw'ibice byayo.
Byongeye kandi, granite ifite ubushobozi bwiza bwo kudakoresha imitingito. Mu icupa ry’ibikoresho bitunganya neza, imikorere y’ibikoresho bitandukanye bitunganya izatera imitingito y’ibipimo bitandukanye. Ibyo bitingito bizabangamira inzira yo gutunganya kandi bigira ingaruka ku buryo bwo gutunganya neza. Granite ishobora gufata no kugabanya imitingito yo hanze neza, ikagabanya ingaruka z’imitingito ku bikoresho, igatanga ibidukikije bihamye byo gutunganya neza, kandi ikagenzura ko ibice bitunganyijwe bifite ingano nyayo n’ubwiza bwiza bw’ubuso.
Ikoreshwa ryagutse ry'ibicuruzwa bya granite mu gutunganya neza imashini
Mu bikoresho byo gutunganya neza imashini, ibikoresho bya granite bikoreshwa cyane mu bice byinshi by'ingenzi. Urugero, ibikoresho by'imashini ya granite, nk'igice cy'ibanze gishyigikira ibikoresho, bitanga urubuga ruhamye rwo gukora ku gikoresho cyose cya mashini. Imikorere yacyo ihamye ishobora kwemeza ko igikoresho cya mashini gikomeza kuba neza aho buri gice kigenda mu gihe cyo gukata vuba, gusya neza no gutunganya ibindi bikorwa, bityo bigatuma habaho gutunganya neza cyane.
Inzira zo kuyobora za granite nazo ni ingenzi mu gutunganya neza imashini. Ugereranyije n'inzira zo kuyobora ibyuma gakondo, inzira zo kuyobora za granite zifite imiterere yo kudahuza neza no kugenda neza. Zishobora gutuma ibice by'igikoresho cy'imashini bigenda neza mu gihe cyo kugenda, zikagabanya amakosa mu kugenda no kunoza uburyo bwo gutunganya. Hagati aho, inzira zo kuyobora za granite zifite ubushobozi bwo kudashira neza kandi zimara igihe kirekire, ibyo bikaba bigabanya ikiguzi cyo kubungabunga no kudakora neza kw'ibikoresho.
Mu rwego rw'ibikoresho byo gupima, ibikoresho nk'amasahani ya granite n'ibipimo nabyo bigira uruhare runini. Imbuga zo gupima granite, zifite ubugari buhanitse kandi buhamye, zitanga ibimenyetso byizewe byo gupima neza. Mu gihe cyo gupima ingano no kugenzura imiterere n'aho ibintu bihagaze ku bice bya mekanike neza, imbuga zo gupima granite zishobora kwemeza neza kandi zizewe ibisubizo byo gupima, bigafasha abakozi batunganya vuba kumenya no gukosora amakosa yo gutunganya no kwemeza ubuziranenge bw'ibicuruzwa.
Guteza imbere iterambere ry'inganda zitunganya imashini neza
Bitewe n’uko ibintu bikenerwa mu buhanga n’ubuziranenge bikomeza kunozwa mu bijyanye n’ibicuruzwa mu nganda zitunganya imashini zikoresha ikoranabuhanga rigezweho, akamaro k’ibicuruzwa bya granite karagenda karushaho kugaragara. Ntabwo byongera gusa ubuziranenge n’ubuziranenge bw’ibikoresho, ahubwo binatanga inkunga ikomeye mu guhanga udushya no guteza imbere ikoranabuhanga ryo gutunganya imashini zikoresha ikoranabuhanga rigezweho. Binyuze mu gukoresha ibicuruzwa bya granite, ibigo bitunganya imashini zikoresha ikoranabuhanga rigezweho bishobora gukora ibicuruzwa bifite ubuziranenge bwo hejuru kugira ngo bihuze n’ibyo inganda zikora mu nganda zikora ibintu bigezweho nk’indege, amakuru y’ikoranabuhanga, n’ibikoresho by’ubuvuzi zikenera, kandi binazamure ubushobozi bwazo bwo guhangana ku isoko.
Mu gihe kizaza, hamwe n’iterambere rihoraho ry’ikoranabuhanga ryo gutunganya no kwiyongera k’ubusabe bw’ibicuruzwa bikozwe mu buryo bunoze, ibikoresho bya granite bizagira uruhare runini mu bijyanye no gutunganya neza imashini. Guhuza kwayo cyane n’ikoranabuhanga rigezweho mu nganda bizarushaho guteza imbere iterambere ry’inganda zitunganya neza imashini zikozwe mu buryo bunoze ku buryo bworoshye kandi bunoze, kandi bifashe inganda zikora mu rugendo rushya rugana ku iterambere rigezweho kandi ry’ubwenge.
