Humidity Inogona Kukanganisa Granite Precision Surface Plates?

Granite chaiyo mahwendefa epamusoro ave achionekwa seimwe yenheyo dzakavimbika mune dimensional metrology. Ivo vanopa yakagadzikana referensi nzvimbo yekuongorora, calibration, uye yakakwirira-chaiyo zviyero mumaindasitiri akadai semiconductor kugadzira, aerospace, CNC machining, uye optical metrology. Kunyange kukosha kwavo kusingabvunzwe, pane kunetseka kunowanzo kuoneka mumaforamu ehunyanzvi uye kubvunza kwevatengi:humidity inokanganisa sei mahwendefa epamusoro egranite?Hunyoro hunogona kukonzera gireniti kukanganiswa kana kurasikirwa nemazvo here?

Mhinduro, maererano nekutsvagisa uye makumi emakore eruzivo rweindasitiri, inosimbisa. Granite, kunyanya yakakwira-density dema girenati, chinhu chakanyanya kugadzikana chakasikwa chine hygroscopic zvimiro zvisina basa. Kusiyana nematombo ane porous akadai semarble kana limestone, granite inoumbwa kuburikidza neinononoka crystallization ye magma yakadzika mukati meNyika. Iyi nzira inoguma mune dense chimiro chine yakaderera porosity. Mukutaura, izvi zvinoreva kuti granite haitore mvura kubva mumhepo, uye haina kuzvimba kana kukanganisa munzvimbo dzine hunyoro.

Muchokwadi, uku kuramba hunyoro ndicho chimwe chezvikonzero zvakakosha nei granite yakatsiva simbi yakakandwa mune akawanda metrology application. Apo simbi yakakandwa inogona kuita ngura kana kuita ngura kana yaiswa muhunyoro hwepamusoro, giraniti rinoramba rakagadzikana mumakemikari. Kunyangwe mumashopu ane mwero wehunyoro hunopfuura 90%, mahwendefa egranite chaiwo anochengetedza kugadzikana kwawo uye kupfava. Miedzo inoitwa munzvimbo dzakadzorwa inosimbisa kuti flatness yegranite pamusoro peplate inoramba iri mukati me micrometer tolerances zvisinei nekushanduka kwehunyoro hwemhepo.

Izvo zvakati, nepo granite pachayo isingakanganiswe nehunyoro, iyo yese yekuyera nharaunda ichiri kukosha. Condensation inogona kuitika mumashopu asina kurongeka zvakanaka apo tembiricha inodonha kamwe kamwe, uye kunyangwe giraniti isingaite ngura, mvura yakanyungudutswa inogona kusiya guruva kana zvinosvibisa zvinokanganisa kuyerwa. Zviridzwa zvakaiswa pagranite, senge dial gauges, mazinga emagetsi, kana kurongeka michina yekuyeresa, kazhinji anotarisisa mamiriro ezvakatipoteredza kupfuura chigadziko chegranite pachacho. Nechikonzero ichi, marabhoritari uye maworkshops anokurudzirwa kuchengetedza tembiricha yakagadzikana uye humidity control kwete yegranite chete asiwo yezviridzwa zvinoenderana nazvo.

Iyo yepamusoro yehunyoro inopikisa yegranite inonyanya kukosha mumaindasitiri umo mamiriro ekunze akaoma kudzora. Semiconductor machira, zvivakwa zvemuchadenga, uye marabhoritari ekutsvagisa anowanzo shanda zvine mwero wezvakatipoteredza, asi kugadzikana kwegranite kunovimbisa imwezve chengetedzo. Munzvimbo dzine mamiriro ekunze akanyorova, kubva kuSoutheast Asia kusvika kumahombekombe eEurope, mahwendefa egranite agara achiratidza kuva akavimbika pane dzimwe nzira.

PaZHHIMG®, iyo granite nhema yakasarudzwa kune chaiyo zvigadzirwa inopa yakatokura mwero wekuita. Nehuremu hunosvika 3100 kg pa cubic mita uye mwero wekutora mvura wepasi pe0.1%, inopa kugadzikana kusingaenzaniswi. Izvi zvinovimbisa kuti flatness uye kurongeka kunochengetwa kwenguva yakareba yekushandiswa. Vatengi mukugadzira semiconductor, optics, CNC machining, uye nyika metrology masisitimu vanotsamira pane izvi zvivakwa kana kunyatsojeka kuchidikanwa.

Chimwe chinhu chokufunga nezvacho ndechekuchengetedza. Kunyange zvazvo granite isingakanganisi nehunyoro, maitiro akanaka anobatsira kuwedzera hupenyu hwayo hwebasa. Kugara uchichenesa nemucheka usina lint kunodzivirira kuunganidzwa kweguruva. Zvivharo zvinodzivirira zvinogona kuchengetedza nzvimbo dzisina zvidimbu zvemhepo kana ndiro isiri kushandiswa. Periodic calibration ine zviridzwa zvakasimbiswa inosimbisa huchokwadi hwenguva refu, uye izvi zvinonyanya kukosha munzvimbo dzakakwirira-chaizvo uko kushivirira kunogona kusvika padanho re-sub-micron. Muzviitiko zvese izvi, kupikisa kwegranite kune humidity kunoita kuti basa rive nyore uye rive nekufungidzira kupfuura nesimbi kana zvimwe zvinhu.

Mubvunzo wekunyorova uye mahwendefa egraniti chaiwo anowanzobva mukunetseka kwechisikigo: muuinjiniya hwechokwadi, kunyangwe diki pesvedzero yezvakatipoteredza inogona kuve nemhedzisiro inoyerwa. Tembiricha, semuenzaniso, chinhu chakakosha mukugadzikana kwedimensional. Granite's low coefficient of thermal expansion inotoita kuti ive imwe yezvakanakisa zvinhu zvekudzora shanduko iyi. Kana zvasvika pakunyorova, zvakadaro, mainjiniya anogona kuzorora aine chokwadi chekuti granite ndeimwe yesarudzo dzakavimbika dziripo.

Kune makambani nemarabhoritari anodyara mari yakawanda muzvivakwa zvemetrology, sarudzo yezvinhu haisi yekungoita chete nhasi asiwo nezve kugadzikana kwemakumi emakore ari kuuya. Granite yakaratidza kuti ishamwari yenguva refu muushumiri uhu. Kupokana kwayo nekunyorova kunoreva kuti inogona kuiswa uye kushandiswa munzvimbo dzakasiyana siyana, kubva kudzimba dzakachena kuenda kune inorema-basa indasitiri nzvimbo, pasina kunetsekana kuti unyoro huchakanganisa kurongeka kwayo.

Mukupedzisa, humidity haina kutyisidzira kugadzikana kana kurongeka kwegranite pamusoro peplateti. Kutenda kune dense, isiri-hygroscopic hunhu, granite inoramba isina kubatwa nehunyoro uye inoenderera ichipa yakagadzikana referensi inodiwa mune yemazuva ano metrology. Nepo kudzora kwezvakatipoteredza kunoramba kwakakosha kune zviridzwa uye kurongeka kwese, iyo granite pachayo inogona kuvimbwa nayo kuramba shanduko dzine chekuita nehunyoro. Ichi ndicho chikonzero, mumaindasitiri uye kutenderera pasirese, granite inoramba iri chinhu chesarudzo kune chaiyo yekuyera nheyo.

KuZHONGHUI Group (ZHHIMG®), ruzivo urwu haruna kungofungidzira asi rwunoratidzwa zuva nezuva mukubatana nemakambani eFortune 500, mayunivhesiti anotungamira, uye masangano enyika metrology. Kune mainjiniya ari kutsvaga kuvimbika kwenguva refu, mahwendefa epamusoro egranite anomiririra kwete tsika chete asiwo remangwana rekuyera kwekupedzisira-chaizvo.
