Mu rwego rwo kugenzura neza imashini, ubwiza n'ubunyangamugayo bw'ibikoresho byo kugenzura vis bigira ingaruka ku buryo butaziguye ku igenzura ry'ubuziranenge bw'ibice byohereza vis ibyuma. Guhitamo ibikoresho by'ingenzi by'icyuma gipima vis ibyuma ni ingenzi mu kugena igihe cyo gukora n'imikorere y'ibikoresho. Igice cyihariye cya granite cy'ibikoresho byo kugenzura vis ibyuma, hamwe n'inyungu zacyo zidasanzwe mu bumenyi bw'ibikoresho, cyageze ku ntambwe yo kongera igihe cyo gukora ku myaka 12 ugereranije n'ibikoresho by'icyuma, bizana impinduka zikomeye mu nganda zigenzura neza imashini.
Inzitizi z'ibice by'icyuma gishongeshejwe
Icuma gishongeshejwe cyakoreshejwe cyane mu gukora ibikoresho byo gupima vis by'icyuma gishongeshejwe kubera ko bihendutse kandi bikagira ubukana runaka. Ariko, ibyuma bishongeshejwe bifite inenge nyinshi mu mikoreshereze yabyo. Ubwa mbere, ibyuma bishongeshejwe bifite ubushyuhe buke. Mu gihe cy'ikoreshwa ry'icyuma gipima vis by'icyuma gishongeshejwe, ubushyuhe buturuka ku bikoresho ubwabyo ndetse n'impinduka mu bushyuhe bw'ibidukikije bishobora gutuma ibice by'icyuma gishongeshejwe bihinduka, bigahindura uburyo bwo kumenya vis by'icyuma gishongeshejwe. Uko igihe cyo kubikoresha kigenda cyiyongera, ingaruka zo guhindagurika kw'ubushyuhe zituma amakosa yo gupima akomeza kwiyongera. Icya kabiri, ubudahangarwa bw'icyuma gishongeshejwe bugabanuka. Mu gihe cyo kugenda kenshi kw'vis y'icyuma gishongeshejwe no kugenzura, ubuso bw'igice cy'icyuma gishongeshejwe bushobora kwangirika bitewe no gukururana, bigatuma aho gishyirwa hakwirakwira harushaho kwiyongera bityo bikagabanya ubuziranenge n'ubudahemuka bw'ibikoresho byo kugenzura. Byongeye kandi, ibyuma bishongeshejwe bifite ubudahangarwa buke bwo kwangirika. Mu bidukikije birimo gazi itose cyangwa iy'ingufu, ibice by'icyuma gishongeshejwe bishobora kwangirika no kwangirika, bigatuma igihe cyo gukoresha ibikoresho kigabanuka cyane.
Ibyiza by'ibice bya granite mu bumenyi bw'ibikoresho
Granite, nk'igikoresho cyiza cyo gukoresha mu bikoresho byihariye byo kugenzura vis, ifite ibyiza karemano. Imiterere yayo y'imbere ni minini kandi ingana, ifite igipimo gito cyane cy'ubushyuhe, akenshi iri hagati ya 5 na 7 × 10⁻⁶/℃, kandi ntabwo ihinduka bitewe n'impinduka z'ubushyuhe. Ibi bituma vis ipima vis igumana ingano n'imiterere y'ibice bya granite ihamye ndetse no mu gihe kirekire ikoreshwa cyangwa ihindagurika rikomeye mu bushyuhe bw'ibidukikije, itanga icyerekezo cyizewe cyo kumenya vis ipima vis no kwemeza ko amakuru yo gupima ari ukuri.
Ku bijyanye no kudashira, ubukana bwa Mohs bwa granite bushobora kugera kuri 6-7, buruta ubw'icyuma gishongeshejwe. Mu gihe cyo kugenda kenshi kwa screw y'icyuma gishongeshejwe, ubuso bw'igice cya granite ntibupfa kwambarwa kandi bushobora guhora bufite aho buhuriye neza, bigatuma screw y'icyuma ishaje iguma neza igihe kirekire. Dukurikije imibare y'amakuru akoreshwa mu buryo bufatika, igipimo cyo kugabanuka neza kw'icyuma gipima screw y'icyuma gikoresha ibice bya granite kiri munsi y'ikigero cya 80% ugereranyije n'icy'icyuma gishongeshejwe mu gihe kimwe cy'akazi.
Mu bijyanye no kurwanya ingese, granite ni ibuye karemano rifite imiterere ihamye ya shimi kandi ntirigira ingaruka ku bintu bisanzwe bya aside cyangwa alkaline. Ndetse no mu nganda zigoye, ibice bya granite ntibizangirika kubera ingese, bikongera igihe cyo gukora cy’icyuma gipima ibyuma.
Ingaruka zitangaje ku ikoreshwa n'agaciro k'inganda
Ingaruka zifatika z'ikoreshwa ry'ibice byihariye bya granite ku bikoresho bipima ibyuma bipima icyuma ni nziza cyane. Binyuze mu iperereza ryakozwe n'ibigo byinshi bikora imashini, byagaragaye ko igihe cy'imikorere y'ibikoresho bipima ibyuma bipima icyuma bikoresha icyuma gishongeshejwe ari imyaka 8, mu gihe nyuma yo gukoresha ibikoresho bipima icyuma gipima icyuma, igihe cy'imikorere y'ibikoresho bipima icyuma gipima icyuma gishobora kongerwa kugeza ku myaka 20, ni ukuvuga imyaka 12 yose. Ibi ntibigabanya gusa ikiguzi cy'ibigo cyo gusimbuza ibikoresho bipima, ahubwo binagabanya igihe cyo kudakora giterwa n'imikorere mibi y'ibikoresho kandi bikongera umusaruro.
Mu rwego rwo guteza imbere inganda, ikoreshwa ry'ibice bya granite ryateje imbere ikoranabuhanga ryo kumenya neza. Igihe cyayo kirekire cyane kandi ikora neza bitanga icyizere cyizewe cyo kugenzura neza vis, bifasha inganda zikora imashini gukora ibicuruzwa byiza kandi bikongera ubushobozi bwo guhangana n'inganda zose.
Ibice byihariye bya granite byo gupima vis byatsinze neza inenge z'ibice by'icyuma gishongeshejwe bitewe n'inyungu z'ubumenyi bw'ibikoresho, bigeraho birushaho kwiyongera mu gihe cyo gukora. Mu gihe kizaza, bitewe n'ubwiyongere bukomeje bw'ubusabe bwo kugenzura neza, ibice bya granite bizagira uruhare runini mu nzego nyinshi kandi bitange inkunga ikomeye mu iterambere ry'inganda zikora neza.
