Coefficente yo kwagura umurongo wa granite mubisanzwe ni 5.5-7.5x10 - ⁶ / ℃. Nyamara, ubwoko butandukanye bwa granite, coefficente yo kwaguka irashobora kuba itandukanye gato.
Granite ifite ubushyuhe bwiza butajegajega, bugaragarira mubice bikurikira:
Ihinduka rito ry'ubushyuhe: bitewe na coefficient yo kwaguka kwayo, guhindura ubushyuhe bwa granite ni bito iyo ubushyuhe buhindutse. Ibi bituma ibice bya granite bigumana ubunini nubunini butajegajega mubushuhe butandukanye, ibyo bikaba bifasha kumenya neza ibikoresho byuzuye. Kurugero, mubikoresho byo gupima neza-neza, gukoresha granite nkibanze cyangwa akazi, nubwo ubushyuhe bwibidukikije bufite ihindagurika runaka, ihindagurika ryumuriro rishobora kugenzurwa murwego ruto, kugirango hamenyekane neza ibisubizo byapimwe.
Kurwanya ubushyuhe bwiza bwumuriro: Granite irashobora kwihanganira urwego runaka rwubushyuhe bwihuse nta gucika cyangwa kwangirika kugaragara. Ni ukubera ko ifite ubushyuhe bwiza nubushyuhe, bushobora kohereza ubushyuhe vuba kandi buringaniye mugihe ubushyuhe bwahindutse, bikagabanya ubukana bwimbere bwimbere. Kurugero, mubidukikije bimwe na bimwe bitanga umusaruro, mugihe ibikoresho bitangiye cyangwa bihagaritse gukora, ubushyuhe buzahinduka vuba, kandi ibice bya granite birashobora guhuza neza niyi mpanuka yumuriro kandi bikagumya guhagarara neza mubikorwa byabo.
Ihinduka ryiza rirambye: Nyuma yigihe kinini cyo gusaza karemano nibikorwa bya geologiya, imihangayiko yimbere ya granite yararekuwe ahanini, kandi imiterere irahagaze. Muburyo bwigihe kirekire bwo gukoresha, nubwo nyuma yubushyuhe bwinshi bwikurikiranya, imiterere yimbere ntabwo yoroshye guhinduka, irashobora gukomeza kubungabunga ubushyuhe bwiza, itanga inkunga yizewe kubikoresho bihanitse.
Ugereranije nibindi bikoresho bisanzwe, ituze ryumuriro wa granite riri murwego rwo hejuru, ibikurikira nigereranya hagati ya granite nicyuma, ibikoresho bya ceramic, ibikoresho bikomatanya mubijyanye nubushyuhe bwumuriro:
Ugereranije n'ibikoresho by'icyuma:
Coefficient yo kwagura ubushyuhe bwibikoresho rusange byicyuma ni binini. Kurugero, coefficente yo kwagura umurongo wibyuma bisanzwe bya karubone ni nka 10-12x10 - ⁶ / ℃, naho coefficente yo kwagura umurongo wa aluminiyumu ni nka 20-25x10 - ⁶ / ℃, ikaba isumba cyane granite. Ibi bivuze ko iyo ubushyuhe buhindutse, ubunini bwibikoresho byicyuma burahinduka cyane, kandi biroroshye kubyara imihangayiko yimbere imbere kubera kwaguka kwubushyuhe no kugabanuka gukonje, bityo bikagira ingaruka kumyizerere no guhagarara neza. Ingano ya granite ihinduka gake mugihe ubushyuhe buhindagurika, bushobora gukomeza neza imiterere yumwimerere nukuri. Ubushyuhe bwumuriro bwibikoresho byicyuma mubusanzwe buri hejuru, kandi mugihe cyo gushyushya byihuse cyangwa gukonjesha, ubushyuhe buzakorwa vuba, bikavamo itandukaniro rinini ryubushyuhe hagati yimbere nubuso bwibintu, bikaviramo guhangayika. Ibinyuranye, ubushyuhe bwumuriro wa granite ni buke, kandi ubushyuhe bugenda buhoro, bushobora kugabanya kubyara ingufu zumuriro kurwego runaka kandi bikerekana neza ubushyuhe bwumuriro.
Ugereranije nibikoresho bya ceramic:
Coefficente yo kwagura amashyanyarazi yibikoresho bimwe na bimwe bikora cyane bya ceramic birashobora kuba bike cyane, nka ceramika ya silicon nitride, iyo coefficente yo kwagura umurongo igera kuri 2.5-3.5x10 - ⁶ / ℃, iri munsi ya granite, kandi ifite inyungu zimwe na zimwe mukutuza ubushyuhe. Nyamara, ibikoresho bya ceramic mubisanzwe biroroshye, guhangana nubushyuhe bwumuriro birakennye cyane, kandi ibice cyangwa nibice byoroshye kugaragara mugihe ubushyuhe bwahindutse cyane. Nubwo coefficente yo kwagura amashyanyarazi ya granite iri hejuru gato ugereranije nubutaka bwihariye bwihariye, ifite ubukana bwiza hamwe no guhangana nubushyuhe bwumuriro, irashobora kwihanganira urwego runaka rwimihindagurikire yubushyuhe, mubikorwa bifatika, kubintu byinshi bihindura ubushyuhe budasanzwe bukabije, ubushyuhe bwumuriro wa granite burashobora kuzuza ibisabwa, kandi imikorere yabyo iringaniza, igiciro ni gito.
Ugereranije n'ibikoresho byinshi:
Bimwe mubikoresho byateye imbere bishobora kugera kuri coefficient nkeya yo kwagura ubushyuhe hamwe nubushyuhe bwiza bwumuriro hifashishijwe igishushanyo mbonera cya fibre na matrix. Kurugero, coefficente yo kwagura ubushyuhe bwa karubone fibre ikomezwa irashobora guhindurwa ukurikije icyerekezo nibiri muri fibre, kandi irashobora kugera kubiciro biri hasi cyane mubyerekezo bimwe. Ariko, gahunda yo gutegura ibikoresho byinshi iragoye kandi igiciro ni kinini. Nkibintu bisanzwe, granite ntabwo ikenera inzira igoye yo gutegura, kandi igiciro ni gito. Nubwo bidashobora kuba byiza nkibikoresho bimwe na bimwe byo mu rwego rwo hejuru bikomatanyije mu bipimo bimwe na bimwe byerekana ubushyuhe bw’umuriro, bifite ibyiza mu bijyanye n’imikorere y’ibiciro, bityo bikoreshwa cyane mubikorwa byinshi bisanzwe bifite ibyo bisabwa kugirango ubushyuhe bwumuriro. Ni izihe nganda zikoreshwa muri granite, ihindagurika ry'ubushyuhe ni ikintu cyingenzi? Tanga amakuru yihariye yikizamini cyangwa ibibazo bya granite yumuriro. Ni irihe tandukaniro riri hagati yubwoko butandukanye bwa granite yumuriro uhagaze?
