Granite VS icyuma gishongeshejwe: Itandukaniro mu guhindura ubushyuhe hagati y’ibikoresho byombi nyuma y’amasaha 8 byapimwe hakoreshejwe ishusho y’ubushyuhe.

Ese?
Mu rwego rwo gukora no kugenzura neza, imikorere y’ibikoresho mu bijyanye no guhindura ubushyuhe ni ikintu cy’ingenzi kigena uburyo ibikoresho bikoresha neza kandi byizewe. Granite n’icyuma gishongeshejwe, nk’ibikoresho bibiri bisanzwe bikoreshwa mu nganda, byakuruye abantu benshi kubera itandukaniro ry’imikorere yabyo mu bidukikije birimo ubushyuhe bwinshi. Kugira ngo tugaragaze imiterere y’ubushyuhe bw’ibicuruzwa byombi, twakoresheje umuhanga mu gushushanya ubushyuhe kugira ngo akore ibizamini by’akazi by’amasaha 8 ku mbuga za granite n’icyuma gishongeshejwe bifite imiterere imwe, bigaragaza itandukaniro nyaryo binyuze mu makuru n’amashusho.

Igishushanyo mbonera cy'igerageza: Kwigana imiterere igoye y'akazi no kubona neza itandukaniro
Muri ubu bushakashatsi, hatoranijwe urubuga rwa granite n'icyuma gikozwe mu cyuma gifite ingano ya 1000mm × 600mm × 100mm. Mu nyubako y’inganda yiganye (ubushyuhe 25±1℃, ubushuhe 50%±5%), binyuze mu gukwirakwiza amasoko y’ubushyuhe ku buso bw’urukuta (kwigana uburyo ubushyuhe bukorwa mu gihe cy’ikoreshwa ry’ibikoresho), uru rubuga rwakoraga ku ngufu za 100W mu gihe cy’amasaha 8. Ishusho y’ubushyuhe ya FLIR T1040 (ifite ubushobozi bwo gupima ubushyuhe bwa 0.02℃) hamwe na sensor yo kwimura ya laser ifite ubuhanga bwo hejuru (ifite ubushobozi bwo gupima ±0.1μm) byakoreshejwe mu gukurikirana ikwirakwizwa ry’ubushyuhe n’ihinduka ry’ubuso bw’urukuta mu gihe nyacyo, kandi amakuru yafatwaga rimwe mu minota 30.
Ibisubizo byapimwe: Tekereza itandukaniro ry'ubushyuhe hanyuma upime icyuho cy'ihinduka ry'ikirere
Amakuru aturuka ku ishusho y'ubushyuhe agaragaza ko nyuma y'uko urwego rw'icyuma rumaze isaha imwe rukora, ubushyuhe ntarengwa bwo hejuru bw'ubuso bwageze kuri 42℃, ari na 17℃ hejuru y'ubushyuhe bwa mbere. Nyuma y'amasaha umunani, ubushyuhe bwazamutse bugera kuri 58℃, maze habaho ikwirakwira ry'ubushyuhe butandukanye, aho ubushyuhe bwa 8℃ hagati y'inkombe n'imbere. Uburyo bwo gushyushya urwego rw'icyuma cya granite buba bworoshye. Ubushyuhe buzamuka gusa bugera kuri 28℃ nyuma y'isaha 1 kandi bugahagarara kuri 32℃ nyuma y'amasaha 8. Itandukaniro ry'ubushyuhe bwo hejuru rigenzurwa muri 2℃.
Dukurikije amakuru yavuye mu bushakashatsi, mu masaha 8, imiterere y’ubugari mu gice cyo hagati cy’icyuma cyashongeshejwe yageze kuri 0.18mm, naho imiterere y’ubugari ku nkengero yari 0.07mm. Ibinyuranye n’ibyo, imiterere ntarengwa y’urwego rwa granite ni 0.02mm gusa, munsi ya 1/9 cy’urwego rw’icyuma cyashongeshejwe. Imiterere y’igihe nyacyo ya sensor ya laser nayo iremeza iki gisubizo: Imiterere y’ubugari bw’urwego rwa icyuma cyashongeshejwe irahindagurika cyane, mu gihe imiterere y’urwego rwa granite ihagaze neza, igaragaza ubushyuhe bukomeye cyane.
Isesengura ry'amahame: Imiterere y'ibikoresho igena itandukaniro mu guhindura ubushyuhe
Impamvu nyamukuru y’ihindagurika rikomeye ry’ubushyuhe bw’icyuma gishongeshejwe ishingiye ku gipimo cyacyo cyo hejuru cy’ubushyuhe (hafi 10-12 × 10⁻⁶/℃), hamwe n’ikwirakwizwa rya grafiti imbere ritaringaniye, bigatuma umuvuduko uhindagurika w’ubushyuhe no kurema igipimo cy’ubushyuhe mu gace runaka. Hagati aho, icyuma gishongeshejwe gifite ubushobozi buke bw’ubushyuhe, kandi ubushyuhe bwacyo bwiyongera vuba iyo cyinjije ubushyuhe bungana. Mu buryo bunyuranye, igipimo cy’ubushyuhe bwa granite ni (4-8) × 10⁻⁶/℃ gusa. Imiterere yacyo ya kristu ni minini kandi ingana, ifite ubushobozi buke bwo gutwara ubushyuhe kandi bungana. Hamwe n’ubushobozi bwacyo bwo gutwara ubushyuhe bwinshi, gishobora gukomeza kurangwa n’ubudahangarwa mu bidukikije bishyuha cyane.
Ubumenyi bw'ishyirwa mu bikorwa: Amahitamo agena ubuziranenge, ituze ritanga agaciro
Mu bikoresho nk'ibikoresho by'imashini zipima neza n'imashini zipima ibintu bitatu, guhinduka k'ubushyuhe kw'ibishingiriro by'icyuma gishongeshejwe bishobora gutera amakosa yo gutunganya cyangwa kugenzura, bigagira ingaruka ku musaruro w'ibicuruzwa byujuje ibisabwa. Igishingiriro cya granite, gifite ubushyuhe buhamye, gishobora kwemeza ko ibikoresho bigumana ubuziranenge bwo hejuru mu gihe cy'imikorere y'igihe kirekire. Nyuma y'uko ikigo runaka gikora ibice by'imodoka cyasimbuje urubuga rw'icyuma gishongeshejweho urubuga rwa granite, igipimo cy'amakosa y'ibice by'ubuziranenge cyagabanutse kuva kuri 3.2% kigera kuri 0.8%, kandi umusaruro wiyongereyeho 15%.
Binyuze mu kwerekana neza no gupima neza ishusho y'ubushyuhe, itandukaniro mu guhindura ubushyuhe hagati ya granite n'icyuma gishongeshejwe rihita rigaragara. Mu nganda za none ziharanira ubuziranenge buhanitse, guhitamo ibikoresho bya granite bifite ubushyuhe buhamye nta gushidikanya ko ari igikorwa cyiza cyo kunoza imikorere y'ibikoresho no kwemeza ko ireme ry'ibicuruzwa ari ryo rikwiye.
