Mu rwego rw'ubuhanga mu by'ubuhanga n'ibipimo, ibice by'ubuhanga mu by'ibumba rya granite—nk'amasafuriya yo hejuru, imashini zishingiyeho, n'ameza y'urumuri—byubahirizwa kubera ko bihamye, bikomeye kandi birwanya ingese. Igice cy'ibumba rya granite cyiza cyane, iyo cyitabwaho neza, gishobora kugumana ubuziranenge bwacyo no kuba gito mu myaka ibarirwa muri za mirongo, kikaba ishingiro rihamye ry'ibipimo byawe by'ingenzi cyane. Ariko, ndetse n'ibumba rya granite riramba cyane ntirigira ingaruka mbi ku bidukikije n'imikoreshereze yaryo. Kugumana ubuziranenge bw'igihe kirekire si ikintu gihoraho; ni inyigisho ihoraho isaba gusobanukirwa byimbitse uburyo bwo kugenzura ibidukikije, kubicunga neza, no kubibungabunga vuba.
Gusobanukirwa neza Ikigo cy’Ibidukikije
Umwanzi ukomeye w’igenzura ry’igihe kirekire si ukwangirika kwa buri munsi, ahubwo ni ibidukikije bidacunzwe neza. Kugira ngo ibice byawe bya granite bigumane ubuziranenge bwabyo ku rwego rwa micron, ugomba kubanza gushyiraho urufatiro ruhamye.
Ubushyuhe ni bwo buhinduka bw'ingenzi cyane. Granite ifite igipimo gito cyane cyo kwaguka k'ubushyuhe, ariko si zeru. Kugira ngo habeho ubuziranenge bwo hejuru, ibice bigomba kuba biri muri laboratwari igenzura ubushyuhe, byaba byiza bibitswe kuri 20°C (±2°C). Ubushyuhe butunguranye cyangwa kwibasirwa n'izuba, imiyoboro y'umwuka ushyushya, n'imiyoboro y'ubushyuhe bishobora gutera ubushyuhe bukabije. Ubu bushyuhe butera umuvuduko w'imbere mu ibuye, bigatera ubusembwa bw'igihe gito ariko buhambaye bwangiza uburyo bwo gupima. Byongeye kandi, ibikoresho binini cyangwa uduce tw'igipimo bigomba kwemererwa kumera neza ku buso bwa granite amasaha menshi mbere yo gupima kugira ngo hirindwe ko ubushyuhe bushobora guhinduka.
Icy'ingenzi ni uko ishingiro ry'aho ishyirwa. Igice cya granite kiba gihamye kimwe n'icyo gihagazeho. Kigomba gushyirwa ku musingi ukomeye kandi udafite stress. Mu buryo bunoze cyane, ibi akenshi bivuze gukoresha udupapuro two kwitandukanya tw’amashanyarazi kugira ngo dutandukanye granite n’ingufu zo hasi ziterwa n’imashini ziri hafi aho, ibyuma bitwara amashanyarazi, cyangwa ndetse n’amaguru. Mu gushyiraho plate nini yo hejuru, inkunga ikwiye ntishobora kuganirwaho. Igomba gushingira kuri sisitemu yo gushyigikira ifite amanota atatu cyangwa atanu (ubusanzwe ingingo eshatu z’ingenzi zigize mpandeshatu ya isosceles n’ingingo ebyiri z’inyongera). Iyi miterere irinda stress imbere no "gutigita," bigatuma plate igera mu mimerere yayo isanzwe, idafite stress. Nyuma yo kugena urwego rwa mbere, ni byiza cyane kureka igice kikagumaho mu buryo budasubirwaho amasaha 12 kugeza kuri 24 kugira ngo habeho stress zisigaye zishira mbere yo gufata ingero za nyuma zo gupima.
Uburyo bwiza bwo gucunga no gukoresha buri munsi
Iyo ibidukikije bimaze kugenzurwa, igihe cyo kugenzura granite yawe kirambye giterwa cyane n'uburyo ifatwa mu bikorwa bya buri munsi. Ubuso bw'isahani ya granite ni ingenzi cyane, kandi kuyirinda kwangirika kw'umubiri ni ingenzi cyane.
Buri gihe menya neza ko ubuso bwa granite busukuye neza mbere na nyuma yo kubukoresha. Ivumbi, uduce tw'icyuma, n'uduce duto cyane ni byo bintu bitera gushwanyagurika ku buso. Koresha igitambaro cyoroshye, kidafite ibara ry'umuhondo gitose gato hamwe n'umuti woza pH cyangwa alcohol ifite isuku nyinshi kugira ngo uhanagure ubuso. Irinde imiti ihumanya cyangwa alkaline, kuko ishobora gutonyanga buhoro buhoro ubuso bw'ibuye uko igihe kigenda gihita. Mu gihe ushyira ibikoresho ku isahani, ntuzigere ubikurura cyangwa ngo ubishyire hasi witonze. Ku bice biremereye, koresha imigozi cyangwa imitako ihinduka kugira ngo ukwirakwize uburemere buringaniye kandi wirinde ko ibintu byinshi bishobora gutera stress cyangwa gucikagurika.
Ni ngombwa kandi kwibuka icyo plaque y'ubuso bwa granite atari cyo. Si intebe yo gukoreraho, icyuma cyo gucukura, cyangwa ikindi gikoresho. Ntukigere ukoresha ubuso mu gushushanya, gucura, cyangwa nk'ishingiro ry'ibikorwa bikomeye by'imashini zishobora kwangiza ingaruka. Byongeye kandi, ibikoresho by'ubukorikori bigomba gukurwaho magneti mbere yo gushyirwa kuri plaque. Ubukorikori busigaye bushobora gukurura uduce duto tw'icyuma mu kirere, dushobora gukora nk'ikintu gikurura munsi y'igice kigenda, kigakurura ubuso buto.
Kubungabunga byihuse no Gusubiramo Ibipimo by'Ingengabihe
Nubwo haba hari uburyo bwiza bwo kugenzura ibidukikije no kubikoresha mu buryo bworoshye, kubigenzura igihe kirekire bisaba gahunda yo kubibungabunga. Granite ni ibikoresho bisanzwe, kandi mu myaka myinshi, bishobora guhinduka buhoro buhoro bitewe n'uko ibikoresho bigenda cyangwa bigahagarara. Kubwibyo, kwishingikiriza gusa ku igenzura rya mbere ry'uruganda ni ingaruka zitagombye gufatwa na laboratwari ikora neza.
Shyira mu bikorwa gahunda yo kugenzura mu byiciro. Buri munsi cyangwa buri cyumweru, abakora bagomba gukora igenzura ryihuse ry’amaso kugira ngo barebe niba ubuso bwangiritse kandi bagenzure neza ubugari bw’aho ibintu biri bakoresheje uburyo bwo kugenzura neza imiterere y’ibintu cyangwa imiterere y’inkombe igororotse. Ibi bifasha mu guhangana n’ibibazo byihutirwa cyangwa impinduka zikomeye.
Kugira ngo ugenzure neza igihe kirekire, teganya gahunda yo kuvugurura imiterere y’ibintu mu gihe gisanzwe, akenshi buri mezi 6 kugeza kuri 12, bitewe n’inshuro bikoreshwa n’urwego rw’ubuhanga bukenewe bwo kwihanganira ibintu. Iki gikorwa kigomba gukorwa n’inzobere mu gupima ibintu zibishoboye zikoresheje ibikoresho bishobora gukurikizwa, nk’ibikoresho by’ikoranabuhanga bifite ubushobozi bwo hejuru cyangwa interferometer za laser. Muri iki gikorwa, ubuso bwose burasuzumwa (akenshi mu buryo bw’urusobe rw’amazi cyangwa "inyenyeri") kugira ngo hakorwe ikarita yuzuye y’imiterere y’aho hantu. Iyo habonetse itandukaniro rito, abatekinisiye b’abahanga bakunze gukora isuzuma cyangwa gukata kugira ngo bagarure ubuso ku rugero rwabwo rwa mbere rwa DIN cyangwa ISO tolerance.
Mu kugenzura ibidukikije cyane, gushyira mu bikorwa amabwiriza agenga uburyo bwo kubikoresha neza, no kwiyemeza gukurikiza gahunda yo kuvugurura imiterere y’ibikoresho by’umwuga, uba wizeye ko ibice byawe by’ubuziranenge bwa granite bikomeza kuba igipimo cyizewe. Ubu bwitange ntiburinda gusa ishoramari ryawe, ahubwo, ikiruta byose, bushimangira ubunyangamugayo n’ubwizerwe bwa buri gipimo ikipe yawe ikora.
