Mu isi igezweho ikora neza cyane, plaque y'ubuso bwa granite ni yo ntwari idashimwa ya laboratwari igenzura ubuziranenge. Itanga urwego rw'icyitegererezo rukenewe kuri buri cyiciro cy'igenzura, kuva ku mirimo yoroshye yo gushushanya kugeza ku gupima ibintu bigoye. Ariko, ndetse na granite y'umukara yo mu rwego rwo hejuru si igikoresho cyo "gushyiraho hanyuma ukibagirwa". Kubera ko ukuri kw'umurongo wose w'umusaruro wawe bishingiye ku buryo iri buye ritambitse, kubungabunga no gupima plaque z'ubuso bwa granite yawe ni ngombwa cyane mu mikorere. Hatabayeho gahunda ikomeye yo kubungabunga, ndetse na plaque ya laboratwari yo mu rwego rwa 00 ishobora kwangirika vuba ikaba isoko y'ikosa ryo gupima, bigatuma habaho kwangwa guhenze no kwangirika k'ubuziranenge bw'ibicuruzwa.
Gusobanukirwa Ubuzima bw'Ubuhanga mu Kumenya neza
Isahani y'ubuso bwa granite itoranywa bitewe n'uko ihamye, ihindagurika mu mihindagurikire, kandi irwanya ubushyuhe. Iyo igeze bwa mbere iturutse ku mukozi uyikora, iherekezwa n'icyemezo cyo gupima kigaragaza ko igororotse. Ariko, kuva igihe ishyiriweho, itangira gukorana n'ibidukikije. Gutandukana kw'ibikoresho by'akazi, ivumbi rinini ritera, ndetse n'impinduka nke mu rufatiro rw'inyubako byose bigira uruhare mu iterambere ry'isahani.
Kubungabunga si ukubungabunga gusa isahani isuku; ni ukubungabunga imiterere y'ubutaka akenshi iba iri hagati ya mm 0.001$. Iyo tuvuze "kubungabunga" isahani isanzwe, tuba turimo kuganira ku kwirinda kwangirika. Iyo tuvuze "gupima", tuba turimo kuganira ku gupima no gukosora kwangirika. Muri rusange, ubu buryo butuma urwego rwawe rw'ibanze rugumaho mu buryo buhoraho mu nganda zihora zihinduka.
Inyigisho ya buri munsi ku isuku yo hejuru
Umwanzi ukomeye w'isahani y'ubuso bwa granite ni "umwanda wo mu iduka." Mu nganda zikora, umwuka wuzuyemo uduce duto cyane - ivumbi ry'icyuma, igihu gikonjesha, na silica. Iyo icyuma gikomeye gishyizwe ku isahani y'ubuso itarasukurwa, utwo duce dukora nk'impapuro z'umucanga zo mu nganda. Uko igice cyimurwa hejuru y'ubuso, kirema "uduce duto" cyangwa "ibibaya" muri granite. Uko igihe kigenda gihita, utwo duce duto tuba dufite agaciro gahagije kugira ngo dusenye uburebure cyangwa tubuze igice kwicara ku rugero.
Gusukura buri munsi ni wo murongo wa mbere w’ubwirinzi. Ni ikosa risanzwe gukoresha imashini zisukura ibirahure byo mu rugo cyangwa imashini zisukura ibirahure mu nganda kuri granite. Inyinshi muri zo zirimo imiti ishobora gusiga agahu ka mikorosikopi cyangwa, ikibi kurushaho, kwinjira mu mwenge karemano w’ibuye bigatuma rikurura umukungugu mwinshi. Imashini zisukura ibirahure bya granite zigenewe gukuraho umwanda n’amavuta mu gihe zihinduka burundu, nta bisigazwa bisigaye. Igikorwa cyo gusukura kigomba guhora gikubiyemo igitambaro kidafite ibara kandi kigomba gukorwa mbere na nyuma ya buri gikorwa.
Byongeye kandi, "uburyo" bwo kugera ku isahani ni ingenzi. Abakoresha bagomba gutozwa kutazigera "bajugunya" icyuma kuri granite. Nubwo granite ikomeye cyane, gukubita cyane kw'icyuma gikomeye bishobora gutera "imyanya y'inyenyeri" cyangwa "ibihumyo." Nubwo granite idakunda "ibihumyo" iyo ikubiswe, agace kari hejuru gashobora gutuma ahantu hanini hagomba guterwa amabuye ya silikoni.
Ubumenyi bwo Gupima: Uretse Ishusho
Gupima ni inzira yo kugenzura ko ubugari bw'isahani bugeze ku rwego rwayo rwagenwe (nk'urwego rwa 0, 1, cyangwa 2). Amaduka menshi akora ikosa ryo gutekereza ko isahani ihagaze neza kuko isa neza. Mu by'ukuri, ubusaza ku isahani hafi ya bwose ntibugaragarira amaso. Akenshi biba hagati mu isahani, aho imirimo myinshi yo kugenzura ikorerwa, bigatuma habaho ingaruka z' "igikombe".
Gupima umwuga bikubiyemo ibipimo bibiri bitandukanye: ubugari rusange no gusubiramo neza gusoma. Ubugari rusange busanzwe bupimwa hakoreshejwe ikoranabuhanga cyangwa interferometer ya laser. Umutekinisiye yimura sensor hejuru y'ikibaho mu buryo bwa "Mood's Bridge" cyangwa "Union Jack", akerekana imiterere y'ubuso bwose. Aya makuru akurikiranwa kugira ngo hatagira agace karenga ubugari bwemewe bw'umurongo uhuza imiterere y'ikibaho.
Gusubiramo uburyo bwo gusoma neza, akenshi bikorwa hakoreshejwe "Repeat-O-Meter," bigenzura niba hari aho byangiritse. Bigaragaza uburebure buri kwimurwa hejuru y'agace gato kugira ngo bigerweho neza. Isahani ishobora gutsinda ikizamini rusange cy'ubugari ariko igatsindwa ikizamini cyo gusoma gisubiramo niba hari ahantu hato kandi hashaje cyane mu gace gakoreshwa cyane. Ku nganda zikora ibikorwa byo kohereza ibicuruzwa mu mahanga ku isi, kugira raporo yemewe ya ISO/IEC 17025 akenshi ni itegeko, kuko itanga icyemezo cya NIST cy'ubuziranenge abakiriya mpuzamahanga bakeneye.
Guhinduranya no gucunga imizigo
Kugira ngo bongere igihe hagati y’amasaha ahenze yo kongeramo ibikoresho, ibikoresho by’ikoranabuhanga bitoza gucunga imitwaro. Iyo icyuma cyo hejuru ari kinini, imirimo yo kugenzura igomba kuzungurutswa mu bice bitandukanye by’icyuma. Niba uburebure buhora bushyizwe mu mfuruka y’imbere iburyo, iyo mfuruka izashira mu gihe igice gisigaye cy’icyuma gikomeza kuba cyiza. Mu guhindura ahantu ho gukorera, ubusaza bukwirakwira ku buryo bungana, bigatuma ubugari bugumana ubugari mu gihe kirekire cyane.
Byongeye kandi, uburyo bwo gushyigikira icyuma gipima icyuma—ubusanzwe gipima icyuma gifite amanota atatu cyangwa atanu—bugomba kugenzurwa buri gihe. Granite iraremereye, kandi uko igihe kigenda gihita, icyuma gishobora kwinjira mu butaka bwa sima butaringaniye neza. Nubwo icyuma kidapima icyuma kidapima icyuma kidapima icyuma gipima icyuma (granite) (kubera gukomera kwayo), bishobora kugorana gukoresha urwego rw'ikoranabuhanga mu gihe cyo kugenzura ibikoresho by'ikoranabuhanga. Kugenzura ko icyuma gipima ...
Igihe cyo kongera gusoza ikiganiro: Impamvu yo kudasubira inyuma
Amaherezo, buri gice cy’ubuso kizashira birenze ubushobozi bwacyo. Muri iki cyiciro, gupima ntibiba bihagije; igice kigomba "gusubiramo gufunga." Iyi ni inzira yihariye cyane aho umutekinisiye akoresha diyama cyangwa silicon carbide slurry hamwe n'igice gito "gifunga" kugira ngo ahindure ubuso bube buto.
Gusubiramo umurongo ni ubuhanga kimwe n'ubumenyi. Umutekinisiye agomba gukuramo ibikoresho ahantu hirengeye mu buryo bwihariye, agakomeza kugenzura aho bigeze akoresheje ikoranabuhanga. Ku isahani yirengagijwe cyane, inzira yo kongera gushyiramo umurongo ishobora gufata amasaha menshi cyangwa iminsi. Ariko, iyo ikozwe neza, isubiza isahani uko yari imeze mbere, igasubiza ubuzima bwayo mu buryo busanzwe.
Kugenzura ibidukikije n'ubushyuhe buhamye
Amaherezo, ibidukikije bikikije isahani bigomba gucungwa neza. Granite ifite ubushyuhe bwinshi, bivuze ko bifata igihe kirekire guhindura ubushyuhe. Ariko, iyo isahani yo hejuru ishyizwe munsi y'umwobo wa HVAC cyangwa mu nzira y'izuba riturutse mu idirishya, uruhande rumwe rw'isahani rushobora gushyuha kurusha urundi. Ibi bitera "ubushyuhe" bushobora gutuma isahani ihetama gato.
Nubwo imiterere ya "Zero-Expansion" ya granite yirabura (nk'iy'ibara rya ZHHIMG) igabanya iyi ngaruka, ntabwo iyikuraho burundu ku rwego rwa sub-micron. Byiza ni uko amasahani agomba kubikwa ahantu hagenzurwa ubushyuhe bwa 20°C (68℉) hamwe n'ubushuhe buri hagati ya 40% na 50%. Iyo isahani yimuwe iva aho ipakiye imizigo ikonje ijya muri laboratwari ishyushye, igomba kureka "kwinjira" byibuze amasaha 24 kugeza kuri 48 mbere yuko hageragezwa gupima cyangwa gupima neza.
Umwanzuro: Ishingiro Rikwiye Kurindwa
Kubungabunga no gupima icyuma gipima ubuso bw'amabuye ni ishoramari rihamye. Muri iki gihe aho ubushobozi bwo gukora ibintu burushaho gukomera kurusha mbere hose, ntushobora kugira "ishingiro ryo gushidikanya." Ukurikije gahunda ikomeye yo gusukura buri munsi, gukora neza ibikoresho by'akazi, no kubigenzura buri gihe, uhindura icyuma gipima ubuso bwawe kuva ku ibuye risanzwe ukakigira igikoresho cy'ubuhanga buhanitse.
Ku bashoramari bo mu mahanga ku isi ndetse n'abakora imashini zo mu gace batuyemo, ubutumwa ni bumwe: ubwiza bw'umusaruro wawe ntibushobora kuba bwiza kurusha ubuso bupimirwaho. Fata granite yawe icyubahiro gikwiye, kandi izaguha inkingi y'ukuri ubucuruzi bwawe bukeneye kugira ngo butere imbere ku isoko mpuzamahanga rihanganye.
