Kufunika kokhala ndi kukhazikika kwa miyeso yolondola kwambiri n'kokwanira. Ngakhale kuti granite imatamandidwa padziko lonse lapansi chifukwa cha kukhazikika kwake kwa kutentha komanso kugwedezeka kwake, funso lofala limabuka kuchokera kwa mainjiniya m'madera ozizira: Kodi chinyezi chimakhudza bwanji nsanja yolondola ya granite?
Ndi nkhani yomveka bwino, chifukwa chinthu chilichonse chomwe chimagwiritsidwa ntchito ngati malo owonetsera ma micrometer kapena ma CMM chiyenera kukana kukhudzidwa ndi chilengedwe. Yankho lalifupi ndilakuti: chifukwa cha zinthu zomwe zasankhidwa mosamala komanso momwe zakonzedwera, granite yolondola kwambiri imapirira kwambiri ku chinyezi.
Udindo wa Kumwa Madzi Ochepa mu Metrology
Granite, monga mwala wachilengedwe, ili ndi ma porosity enaake. Komabe, mitundu yeniyeni ya granite wakuda yomwe imagwiritsidwa ntchito ndi ZHHIMG pakugwiritsa ntchito metrology imasankhidwa bwino chifukwa cha kapangidwe kake kolimba komanso kosalala, zomwe zimapangitsa kuti madzi asayamwe kwambiri.
Granite yodziwika bwino ya kalasi ya metrology nthawi zambiri imakhala ndi chiŵerengero choyamwa madzi chochepera 0.13% (mitundu yambiri yapamwamba imakhala yotsika kwambiri, nthawi zambiri pafupifupi 0.07% kapena kuchepera). Khalidwe ili ndi lofunika kwambiri kuti likhale lolondola kwa nthawi yayitali:
- Kuchepetsa Kukula kwa Hygroscopic: Ngakhale kuti zipangizo zina zimatha kutupa kapena kufupika kwambiri zikamayamwa kapena kutulutsa chinyezi (hygroscopic expansion), kuchepa kwa porosity ya granite yolondola kumachepetsa kwambiri izi. Kuchuluka kwa madzi omwe amayamwa ndi mwalawo n'kochepa, zomwe zimaletsa kusintha kulikonse komwe kungakhudze kusalala kwa malo owonetsera.
- Chitetezo ku Dzimbiri: Mwina ubwino wothandiza kwambiri ndi chitetezo chomwe chimapereka ku zida zanu zamtengo wapatali. Ngati mbale ya pamwamba inali ndi ma porosity ambiri, ingasunge chinyezi pafupi ndi pamwamba. Chinyezichi chingayambitse dzimbiri ndi dzimbiri pa zitsulo, zowonjezera, ndi zigawo zomwe zimayikidwa pa granite, zomwe zimapangitsa kuti ziwonongeke msanga komanso kuti ziipitsidwe. Ma porosity ochepa a Black Granite Components athu amachepetsa chiopsezochi, kuthandizira malo opanda dzimbiri.
Chinyezi ndi Kulondola: Kumvetsetsa Chiwopsezo Chenicheni
Ngakhale granite yokha imakana kusintha kwa mawonekedwe kuchokera ku chinyezi cha mlengalenga, tiyenera kufotokoza kusiyana pakati pa kukhazikika kwa zinthuzo ndi kulamulira chilengedwe mu labu yolondola:
| Factor | Zotsatira Zachindunji pa Pulatifomu ya Granite | Zotsatira Zosalunjika pa Dongosolo Loyezera |
| Chiŵerengero cha Kuyamwa kwa Madzi | Kusintha kwa miyeso kosayenera (kuchepa kwa porosity) | Kuchepetsa chiopsezo cha dzimbiri pa zowonjezera ndi ma gauge. |
| Chinyezi Chozungulira (Chokwera) | Kusintha kosafunikira kwa granite slab yokha. | Chofunika Kwambiri: Kuwonjezeka kwa chiopsezo cha kuzizira kwa zipangizo zoyezera zitsulo, zomwe zingakhudze kuwerengera kwa CMM ndi kuwerenga kwa kuwala. |
| Chinyezi Chozungulira (Chochepa) | Kusintha pang'ono kwa granite slab. | Kuwonjezeka kwa magetsi osasinthasintha, komwe kumakopa tinthu tating'onoting'ono tomwe timayambitsa mavuto owonongeka ndi kuphwanyika. |
Monga akatswiri mu Ultra-Precision Platforms, tikukulangizani kuti makasitomala azisunga malo olamulidwa ndi chinyezi, makamaka pakati pa 50% ndi 60% Relative Humidity (RH). Kuwongolera kumeneku sikukhudza kuteteza granite slab koma kuteteza dongosolo lonse la metrology (CMMs, gauges, optics) ndikuwonetsetsa kuti mpweya wokha uli ndi kutentha.
Chitsimikizo cha ZHHIMG cha Kukhazikika Kosatha
Granite yomwe timasankha—yodziwika bwino chifukwa cha kuchuluka kwake kwakukulu komanso tirigu wabwino—imapereka maziko olimba motsutsana ndi kusintha kwa kutentha ndi chinyezi. Kudzipereka kwathu pakugwiritsa ntchito granite yokhala ndi mphamvu yokoka kwambiri kumatsimikizira kuti mumalandira tebulo lolimba, losagwedezeka ndi dzimbiri lomwe lidzasunga kusalala kwake koyambirira komanso kwabwino kwa zaka zambiri, zomwe zimafuna kukonzanso kwa akatswiri kokha chifukwa cha kuwonongeka, osati kusintha kwa chilengedwe.
Mukayika ndalama mu ZHHIMG Precision Granite base, mukuyika ndalama mu maziko opangidwa kuti agwirizane ndi malo aliwonse oyezera kupirira kwambiri.
