Muri laboratwari zikomeye ku isi, haba mu kumenya ibikoresho bya nanoscale, mu gupima ibice by’urumuri bifatika, cyangwa mu gupima mikorosikopi za semiconductor chips, hari ibisabwa cyane kugira ngo habeho ubushishozi n’ubudahangarwa bw’ibipimo. Granite straightedge, hamwe n’imikorere yayo ihebuje, yabaye amahitamo ya mbere kuri laboratwari nyinshi. Ugereranyije n’ubuso busanzwe bw’icyuma gikozwe mu cyuma, ubuziranenge bwayo bushobora kunozwa kugeza kuri 300%, bishingiye ku bimenyetso bya siyansi byimbitse no kugenzura ibintu mu buryo bufatika.
1. Imiterere y'ibikoresho ni yo igena ishingiro ry'ubuziranenge
Ibyuma bicuzwe, nk'ikintu gisanzwe gikoreshwa mu gupima ubuso, nubwo gifite ubukana runaka, gifite inenge. Igipimo cyacyo cyo kwaguka k'ubushyuhe ni hafi 12 × 10⁻⁶ / ℃. Mu gihe ubushyuhe busanzwe buhindagurika muri laboratwari (nk'itandukaniro ry'ubushyuhe bwa 5℃ riterwa no gutangira no guhagarara kwa firigo), ubuso bw'icyuma bucuzwe bufite uburebure bwa metero 1 bushobora guhindukaho 60μm. Byongeye kandi, hari imiterere ya grafiti iri mu cyuma gicuzwe. Gukoreshwa igihe kirekire bishobora gutera stress, bigatuma urwego rw'ubushyuhe rugabanuka buhoro buhoro. Ubu bwoko bw'ihindagurika ry'ubushyuhe n'impinduka mu miterere bizatera ihindagurika ry'amakuru mu gupima, bigira ingaruka zikomeye ku kuri kw'ibyavuye mu bushakashatsi.
Mu buryo bunyuranye, igipimo cyo kwaguka k'ubushyuhe bwa granite straightedge ni (4-8) × 10⁻⁶/℃ gusa, bingana na kimwe cya gatatu cy'icyuma gishongeshejwe. Mu gihe cy'ubushyuhe bumwe bwa 5℃, impinduka y'ingano y'icyuma gishongeshejwe cya metero 1 ni 20-40 μm gusa. Granite ikorwa no gushushanya amabuye y'agaciro nka quartz na feldspar. Ifite imiterere ikomeye kandi ingana kandi nta kibazo cyo kwibasira imbere. Nyuma y'imyaka ibarirwa muri za miriyari y'ibikorwa bya geologi, granite yarashaje mu buryo busanzwe kandi ntizahinduka nk'icyuma gishongeshejwe uko igihe kigenda gihita, bituma urwego rw'ibanze rugumana umutekano mu gihe kirekire.
Icya kabiri, ikoranabuhanga ryo gutunganya rigera ku buhanga bwo hejuru cyane
Mu gihe cyo gutunganya ubuso bw'icyuma gikozwe mu cyuma gikozwe mu cyuma, bitewe n'imiterere y'ibikoresho, ubuziranenge bw'ubugari bushobora kugera kuri ± 5-10 μm gusa. Byongeye kandi, ubuso bw'icyuma gikozwe mu cyuma bukunze kwangirika no gushwanyagurika, bigasaba kubungabungwa no gusya buri gihe. Buri gusya bigira ingaruka ku buziranenge bw'umwimerere bw'ubuso bw'icyuma gikozwe mu cyuma gikozwe mu cyuma.
Ibuye ry’umukara rikoresha ikoranabuhanga ryo gusya neza cyane kandi rihuzwa n’ikoranabuhanga rigezweho ryo kugenzura imibare. Uburemere bwaryo bushobora kugenzurwa muri ± 1-3 μm, kandi bimwe mu bikoresho byo mu rwego rwo hejuru bishobora no kugera kuri ± 0.5μm. Uburemere bwaryo bugera kuri 6 kugeza kuri 7 ku gipimo cya Mohs, kandi ubukana bwaryo bungana n’inshuro 3 kugeza kuri 5 z’icyuma gishongeshejwe. Ntibyoroshye gushwanyagurika cyangwa kwangirika. Nubwo imaze igihe kirekire ikoreshwa, ubuziranenge bw’ubuso bwaryo bushobora kuguma buhamye, bigatuma hadakenerwa gupimwa no kubungabungwa kenshi, bigagabanya cyane ikiguzi cyo gukoresha muri laboratwari n’igihe.
III. Guhuza ibidukikije bituma ibipimo bihoraho bipimwa
Imiterere y’aho ubushakashatsi bukorera ni ingorabahizi kandi irahinduka. Ibintu nk'ubushuhe, guhindagura no kubangamira ingufu za elegitoroniki byose bishobora kugira ingaruka ku buryo buboneye bwo gupima. Ubuso bw'icyuma gishongeshejwe bukunze kwangirika mu kirere gishyushye, bigatuma ubuso burushaho kuba bubi kandi bukagira ingaruka ku buryo buboneye bwo gupima. Hagati aho, ingufu za rukuruzi z'icyuma gishongeshejwe zishobora kubangamira imikorere y'ibikoresho bipima neza by'ikoranabuhanga.
Ibuye ryoroshye rya granite ni ibikoresho bidakoresha icyuma, ntabwo rikoresha rukuruzi kandi ntirikoresha amashanyarazi, kandi ntirishobora kubangamira ibikoresho by'ikoranabuhanga. Igipimo cyaryo cyo kwinjiza amazi kiri munsi ya 0.1%, kandi riracyashobora gukomeza gukora neza mu kirere gifite ubushuhe bwinshi. Byongeye kandi, imiterere yihariye y'amazi ya granite ishobora kwakira neza imitingito y'ibidukikije no kugabanya imivurungano yo hanze. Urugero, muri laboratwari yegereye ibikoresho binini n'ibikoresho, ibuye ryoroshye rya granite rishobora kugabanya hejuru ya 90% by'ingufu zo guhindagura mu isegonda rimwe, mu gihe ubuso bw'icyuma gishongeshejwe busaba amasegonda 3 kugeza kuri 5. Ibi bituma ibuye ryoroshye rya granite ritanga ishusho ihamye yo gupima ndetse no mu bidukikije bigoye.
Icya kane. Amakuru nyayo ahamya ibyiza by'imikorere
Laboratwari mpuzamahanga izwi cyane ya semiconductor yigeze gukora ikizamini cyo kugereranya igihe kirekire ku buso bw’icyuma gishongeshejwe n’ubuso bw’amabuye: Mu gihe cy’igerageza ryo gupima ryamaze iminsi 30 rimara amasaha 8 buri munsi, ikosa ryo gupima ibikoresho bikoresha ubuso bw’icyuma gishongeshejwe ryageze kuri ±45μm. Ibikoresho bikoresha granite straightedge bifite ikosa ryo gukusanya rya ±15μm gusa, kandi iterambere mu kudahindagurika kw’ubuziranenge rigera kuri 300%. Ibisubizo nk’ibyo byagiye byemezwa kenshi muri laboratwari zikomeye mu nzego nyinshi nko mu bumenyi bw’ibikoresho n’ubuhanga bw’amatara, birushaho kwerekana ko granite straightedge idasimburwa mu gupima neza cyane.
Mu gusoza, imiterere y’icyuma cya granite yarenze cyane ubuso bw’icyuma gishongeshejwe bitewe n’inyungu zayo eshatu z’imiterere y’ibikoresho, ikoranabuhanga ryo gutunganya no kwihutisha ibidukikije. Iterambere ryayo rya 300% mu kudahinduka kw’ubuziranenge ntiritanga gusa igipimo cyizewe cyo gupima muri laboratwari ahubwo rinashyiraho urufatiro rukomeye rw’iterambere ry’ubushakashatsi bwa siyansi bugezweho n’ikoranabuhanga ryo gukora ibintu neza. Iyi ni yo mpamvu nyamukuru ituma laboratwari zikomeye ku isi zifite imiterere y’icyuma cya granite yatoranyijwe.
