Kufunika kokhazikika pamlingo wapamwamba kwambiri ndikokwanira. Ngakhale kuti miyala ya granite imayamikiridwa padziko lonse chifukwa cha kukhazikika kwake kwa kutentha ndi kugwedera kwa kutentha, funso lodziwika bwino limabuka kuchokera kwa akatswiri a nyengo yachinyontho: Kodi chinyezi chimakhudza bwanji nsanja yolondola ya granite?
Ndikofunikira, chifukwa chilichonse chomwe chimagwiritsidwa ntchito ngati ma micrometer kapena ma CMM chiyenera kukana kutengera chilengedwe. Yankho lalifupi ndilakuti: chifukwa cha zinthu zomwe zasankhidwa mosamala komanso kukonza, granite yapamwamba kwambiri imalimbana kwambiri ndi chinyezi.
Udindo wa Kutaya Madzi Otsika mu Metrology
Granite, monga mwala wachilengedwe, ali ndi mulingo wina wa porosity. Komabe, mitundu yeniyeni ya granite yakuda yogwiritsidwa ntchito ndi ZHHIMG pakugwiritsa ntchito metrology imasankhidwa ndendende chifukwa cha mawonekedwe ake owundana, owala bwino, omwe amatsogolera kumadzi pang'ono.
Granite yodziwika bwino ya metrology nthawi zambiri imakhala ndi mayamwidwe amadzi ochepera 0.13% (mitundu yambiri yamtengo wapatali imakhala yotsika kwambiri, nthawi zambiri imayandikira 0.07% kapena kuchepera). Khalidweli ndi lofunika kwambiri pakusunga zolondola pakapita nthawi:
- Kuchepetsa Kukula kwa Hygroscopic: Ngakhale zida zina zimatha kutupa kapena kutsika kwambiri zikamayamwa kapena kutulutsa chinyontho (kufalikira kwa hygroscopic), kutsika kwambiri kwa granite yolondola kumalepheretsa izi. Kuchuluka kwa madzi omwe amamwedwa ndi mwalawu ndi wocheperako, kulepheretsa kusintha kulikonse komwe kungakhudze kusanja kwa ndegeyo.
- Kuteteza Ku dzimbiri: Mwina mwayi wothandiza kwambiri ndi chitetezo chomwe chimapereka zida zanu zamtengo wapatali. Ngati mbaleyo ili ndi porosity kwambiri, imatha kusunga chinyezi pafupi ndi pamwamba. Chinyezichi chikhoza kuyambitsa dzimbiri ndi dzimbiri pazitsulo zazitsulo, zowonjezera, ndi zigawo zina zomwe zimayikidwa pa granite, zomwe zimapangitsa kuti munthu asamachedwe msanga ndi kuyeza koipitsidwa. Kuchepa kwa porosity ya Black Granite Components yathu imachepetsa chiopsezochi, kuthandizira malo opanda dzimbiri.
Chinyezi motsutsana ndi Kulondola: Kumvetsetsa Zowopsa Zenizeni
Ngakhale granite yokha imakana kusinthika kwa dimensional kuchokera ku chinyezi cha mumlengalenga, tiyenera kumveketsa bwino kusiyana pakati pa kukhazikika kwa zinthuzo ndi kuwongolera chilengedwe mu labu yolondola:
| Factor | Direct Zotsatira pa Granite Platform | Zotsatira Zachindunji pa Measurement System |
| Kuchuluka kwa Madzi | Kusintha kocheperako (kutsika pang'ono) | Kuchepetsa chiwopsezo cha dzimbiri pazowonjezera ndi ma geji. |
| Chinyezi Chozungulira (Chapamwamba) | Kusinthika kosasinthika kwa granite slab palokha. | Chofunika: Kuwonjezeka kwa chiopsezo cha condensation pa zida zoyezera zitsulo, zomwe zingakhudze kuwerengetsa kwa CMM ndi kuwerengera kwa kuwala. |
| Chinyezi Chozungulira (Chotsika) | Kusintha kosawerengeka ku slab ya granite. | Kuchulukitsa kwamagetsi osasunthika, kukopa tinthu tating'onoting'ono tomwe timayambitsa zovuta komanso kusanja. |
Monga akatswiri a Ultra-Precision Platforms, timalimbikitsa kuti makasitomala azikhala ndi malo otetezedwa ndi chinyezi, pakati pa 50% ndi 60% Relative Humidity (RH). Kuwongolera uku sikungokhudza kuteteza slab ya granite komanso kuteteza makina onse a metrology (CMMs, geji, optics) ndikuwonetsetsa kukhazikika kwa mpweya womwewo.
Chitsimikizo cha ZHHIMG cha Kukhazikika Kukhazikika
Mwala umene timasankha—wodziŵika chifukwa cha kachulukidwe kake kopambana ndi tirigu wabwino—umakhala ndi maziko okhazikika polimbana ndi kusinthasintha kwa kutentha ndi chinyezi. Kudzipereka kwathu pakugwiritsa ntchito miyala ya granite yokhala ndi mphamvu yokoka kwambiri kumatsimikizira kuti mumalandira tebulo loyang'anira lokhazikika, losachita dzimbiri lomwe likhalabe losalala komanso kukhulupirika kwazaka zambiri, zomwe zimafunikira kukonzanso kwakanthawi kwa akatswiri chifukwa chakuvala, osati kuwonongeka kwa chilengedwe.
Mukayika ndalama mu ZHHIMG Precision Granite base, mukuyika ndalama pamaziko opangira zovuta zamalo aliwonse olekerera kwambiri.
