Ma plates a granite precision surface akhala akudziwika kuti ndi amodzi mwa maziko odalirika mu dimensional metrology. Amapereka malo okhazikika omwe amawunikira kuti awonere, kusanja, ndi kuyeza kolondola kwambiri m'mafakitale onse monga kupanga semiconductor, aerospace, CNC Machining, ndi Optical metrology. Ngakhale kufunikira kwawo sikukayikiridwa, pali nkhawa imodzi yomwe nthawi zambiri imawonekera m'mabwalo aukadaulo ndi kufunsa kwamakasitomala:Kodi chinyezi chimakhudza bwanji mbale za granite pamwamba?Kodi chinyezi chingapangitse kuti miyala ya granite iwonongeke kapena kutaya kulondola kwake?
Yankho, malinga ndi kafukufuku ndi zaka zambiri za mafakitale, ndi zolimbikitsa. Granite, makamaka granite yakuda yakuda kwambiri, ndi chinthu chachilengedwe chokhazikika kwambiri chokhala ndi zinthu zosafunikira za hygroscopic. Mosiyana ndi miyala ya porous monga marble kapena laimu, granite imapangidwa kupyolera pang'onopang'ono crystallization ya magma mkati mwa kutumphuka kwa Dziko lapansi. Njirayi imapangitsa kuti ikhale yowuma kwambiri yokhala ndi porosity yochepa kwambiri. Mwachidziwitso, izi zikutanthauza kuti granite sichimamwa madzi kuchokera mumlengalenga, komanso sichimatupa kapena kupunduka m'malo achinyezi.
M'malo mwake, kukana chinyezi ndi chimodzi mwazifukwa zazikulu zomwe granite yalowa m'malo mwa chitsulo choponyedwa muzinthu zambiri zama metrology. Kumene chitsulo chachitsulo chikhoza kuchita dzimbiri kapena kuchita dzimbiri chikakhala ndi chinyezi chambiri, granite imakhala yokhazikika pamankhwala. Ngakhale m'misonkhano yokhala ndi chinyezi chochulukirapo kuposa 90%, mbale za granite zolondola zimasunga kukhazikika kwake komanso kusalala. Mayesero omwe amachitidwa m'madera olamulidwa amatsimikizira kuti flatness ya granite pamwamba mbale imakhalabe mkati mwa micrometer kulolerana mosasamala kanthu za kusintha kwa chinyezi cha mumlengalenga.
Izi zati, ngakhale granite palokha simakhudzidwa ndi chinyezi, chilengedwe chonse choyezera chimakhalabe chofunikira. Condensation imatha kuchitika m'malo osayendetsedwa bwino kutentha kutsika mwadzidzidzi, ndipo ngakhale granite sichita dzimbiri, madzi opindika amatha kusiya fumbi kapena zowononga zomwe zimasokoneza kuyeza. Zida zoyikidwa pa granite, monga ma dial gauges, ma elekitironi, kapena makina oyezera, nthawi zambiri zimakhala zovuta kwambiri ku chilengedwe kusiyana ndi maziko a granite omwe. Pachifukwa ichi, ma laboratories ndi ma workshops akulimbikitsidwa kuti azikhala okhazikika kutentha ndi kutentha kwa chinyezi osati pa granite komanso zida zomwe zimadalira.
Kukaniza kwapamwamba kwa chinyezi cha granite kumakhala kofunikira makamaka m'mafakitale omwe chilengedwe chimakhala chovuta kuwongolera. Nsalu za semiconductor, malo oyendetsa ndege, ndi malo opangira kafukufuku nthawi zambiri amagwira ntchito motsatira miyezo yokhazikika ya chilengedwe, koma kukhazikika kwa granite kumatsimikizira chitetezo china. M'madera omwe ali ndi nyengo yachinyezi, kuyambira kumwera chakum'mawa kwa Asia kupita ku gombe la ku Ulaya, miyala ya granite yatsimikizira kuti ndi yodalirika kuposa njira zina.
Ku ZHHIMG®, granite yakuda yosankhidwa kuti ikhale yolondola kwambiri imapereka magwiridwe antchito apamwamba kwambiri. Ndi kachulukidwe pafupifupi 3100 kg pa kiyubiki mita ndi kuchuluka kwa mayamwidwe amadzi osakwana 0.1%, kumapereka kukhazikika kosayerekezeka. Izi zimatsimikizira kuti flatness ndi zolondola zimasungidwa pakagwiritsidwa ntchito nthawi yayitali. Makasitomala opanga ma semiconductor, optics, CNC Machining, ndi mabungwe amtundu wa metrology amadalira zinthuzi pakafunika kulondola kwambiri.
Mfundo ina yofunika kuiganizira ndiyo kusamalira bwino. Ngakhale kuti granite simakhudzidwa ndi chinyezi, machitidwe abwino amathandiza kukulitsa moyo wake wautumiki. Kuyeretsa nthawi zonse ndi nsalu yopanda lint kumalepheretsa fumbi kudziunjikira. Zovala zodzitchinjiriza zimatha kusunga malo opanda tinthu tating'onoting'ono ta mpweya pomwe mbaleyo siyikugwiritsidwa ntchito. Kuwongolera kwanthawi ndi zida zovomerezeka kumatsimikizira kulondola kwanthawi yayitali, ndipo izi ndizofunikira makamaka m'malo olondola kwambiri pomwe kulolerana kumatha kufikira gawo laling'ono la micron. Muzochitika zonsezi, kukana kwachinyontho kwa granite kumapangitsa kuti ntchitoyi ikhale yosavuta komanso yodziwika bwino kusiyana ndi zitsulo kapena zipangizo zina.
Funso la chinyezi ndi miyala ya granite yolondola nthawi zambiri imabwera kuchokera kuzinthu zachilengedwe: muukadaulo wolondola, ngakhale mphamvu yaying'ono kwambiri ya chilengedwe imatha kukhala ndi zotsatira zoyezeka. Kutentha, mwachitsanzo, ndi chinthu chofunikira kwambiri pakukhazikika kwa dimensional. Kutsika kwamphamvu kwa granite kumapangitsa kuti ikhale imodzi mwazinthu zabwino kwambiri zowongolera kusinthaku. Pankhani ya chinyezi, komabe mainjiniya amatha kukhala otsimikiza kuti granite ndi imodzi mwazosankha zodalirika zomwe zilipo.
Kwa makampani ndi ma laboratories omwe amaika ndalama zambiri pazomangamanga za metrology, kusankha kwazinthu sikungokhudza magwiridwe antchito masiku ano komanso kukhazikika kwazaka zambiri zikubwerazi. Granite yadziwonetsera yokha kukhala bwenzi lanthawi yayitali mu ntchitoyi. Kukaniza kwake ku chinyezi kumatanthauza kuti ikhoza kukhazikitsidwa ndikugwiritsidwa ntchito m'madera osiyanasiyana, kuchokera ku zipinda zoyera kupita ku mafakitale olemera kwambiri, popanda kudandaula kuti chinyezi chidzasokoneza kulondola kwake.
Pomaliza, chinyezi sichimayika chiwopsezo ku kukhazikika kapena kulondola kwa mbale zam'mwamba za granite. Chifukwa cha chikhalidwe chake chowundana, chosakhala cha hygroscopic, granite imakhalabe yosakhudzidwa ndi chinyezi ndipo ikupitiriza kupereka ndondomeko yokhazikika yofunikira mu metrology yamakono. Ngakhale kuwongolera zachilengedwe kumakhalabe kofunikira pazida komanso kulondola kwathunthu, granite yokha imatha kudaliridwa kuti ikana kusintha kokhudzana ndi chinyezi. Ichi ndichifukwa chake, m'mafakitale komanso padziko lonse lapansi, miyala ya granite imakhalabe chida chosankhidwa pamaziko oyezera molondola.
Ku ZHONGHUI Group (ZHHIMG®), kudziwa kumeneku sikungopeka chabe koma kumatsimikiziridwa tsiku ndi tsiku mogwirizana ndi makampani a Fortune 500, mayunivesite otsogola, ndi mabungwe amtundu wa metrology. Kwa mainjiniya omwe akufuna kudalirika kwanthawi yayitali, mbale za granite zimangoyimira miyambo komanso tsogolo la kuyeza kolondola kwambiri.
