Chinhu chega chega chinokura nekupisa. Mubvunzo unokosha kunehwaro hwekuyeraHazvisi zvekuti zvinhu zvinokura here — zvese zvinoita — asi kuti zvinofanotaurwa sei, zvishoma sei, uye zvakaenzana sei. Izwi rekupedzisira iroro, zvakafanana, ndiro iro vatengi vanowanzo kanganwa, uye kazhinji ndiro rinokonzera matambudziko makuru muchitoro.
Granite inotsanangurwa kuti ishandiswezvigadziko zvekuyera zvakaruramazvikuru nekuti coefficient yayo yekuwedzera kwekupisa (CTE) yakaderera kana tichienzanisa nesimbi kana simbi yakakandwa — kazhinji iri pakati pe5 kusvika 8 x 10⁻⁶ pa °C yegranite yemhando yepamusoro, zvichienzaniswa ne11 kusvika 13 x 10⁻⁶ pa °C yesimbi. Papepa, izvozvo zvinoita sekukunda kuri nyore. Muchokwadi, nhamba iri papepa redata inongotaura chikamu chenyaya, uye mainjiniya akatsvaga chiyero chakavanzika anodzokera kwaakabva vanowanzo dzidza zvimwe zvese nenzira yakaoma.
Nei Nhamba yeCTE Isiri Mufananidzo Wese
Hwaro hwegranite hune CTE yakaderera, yakafanana hunoita zvinhu nenzira inofungidzirwa: hunokura kana kudzikira huwandu hunozivikanwa, hushoma sezvo tembiricha ichichinja, uye kuchinja ikoko kunogona kudzoserwa musoftware kana tembiricha ikateverwa. Matambudziko anotanga kana kuwedzera kusina kufanana muchikamu chose.
Granite imhando yechisikigo yequartz, feldspar, uye mica, uye chiyero chaicho chezvicherwa chinosiyana zvichienderana ne quarry uye kunyange ne block. Slab ine chimiro chezviyo chisingawirirane inogona kukura zvishoma zvakasiyana kubva kune imwe nzvimbo kuenda kune imwe pasi pekuchinja kwekushisa kwakafanana, zvichiunza kukanganisa kudiki asi chaiko uko avhareji yeCTE isingafanotaura. Ichi ndicho chimwe chikonzero nei kuenderana kwezvinhu kuchikosha - mugadziri anodhonza dombo kubva mu quarry imwe chete uye block lot batch mushure me batch inowanzo gadzira zvikamu zvinofungidzirwa zvakanyanya kupisa kupfuura mumwe anotsvaga mukana kubva kune chero mutengesi akachipa kota iyoyo.
Kupisa kusina kuenzana kunowedzera izvi. Hwaro hwegranite hwakagara pedyo nehwindo, pasi pechiedza chakananga kune rumwe rutivi, kana pedyo nechishandiso chemuchina chinoburitsa kupisa kwenzvimbo, hahukure sebhuroko rakafanana - hunokotama, zvisinei, kudivi rinotonhorera. Kune akawanda mashandisirwo emaindasitiri, kukanganisa uku hakuna kukosha. Kune sub-micron metrology work - CMMs, laser measurement systems, semiconductor inspection platforms - zvinogona kukwana kuchinja kuverenga kunze kwekutsungirira, uye zvinonyanya kuoma kuongorora nekuti hwaro huchiri "kutaridzika" hwakati sandara uye kunyangwe kuongororwa nekukurumidza.
Izvi Zvinorevei Mumamiriro Echokwadi ELab
Mipimo yakawanda yekuenzanisa, kusanganisira ISO neASME references yekuongorora surface plate, inotaura tembiricha ye20°C nekuda kwechikonzero ichi - kwete nekuti 20°C yakakosha, asi nekuti inopa munhu wese chiyero chakafanana chekuenzanisa nacho. Plate ine certification pa20°C uye inoshandiswa muchitoro chinoshanda pa28°C, pasina kugadziriswa, haisi iyo chaiyo isina kutsanangurwa, asi mushandi ari kuyera tembiricha isina kujeka kana tembiricha isina kuverengerwa pane imwe nzvimbo iri kuitwa.
Mimwe miitiro inoderedza kukanganisa kwekupisa mumunda nguva dzose:
- Rega zvikamu zvegranite zvijairane nemamiriro ekuyera kwemaawa akati wandei - dzimwe nguva husiku hwese kuti zvive nehwaro hukuru - usati wayera zvakakosha, sezvo pakati peslab gobvu pakaenzana zvishoma nezvishoma kupfuura zvinoratidzwa pamusoro payo.
- Ramba uchiyera mabhesi kure nezuva rakananga, maburi eHVAC, uye michina inogadzira kupisa, kunyangwe tembiricha yemukamuri iri pamadziro ichiverengwa nemazvo.
- Nyora tembiricha yemhepo pamwe chete nedata rekuyera kuti uwane basa rakanyatsojeka, pane kufunga kuti "imba inodzorwa nemamiriro ekunze" yakafanana pakupisa kwese.
- Kuwana granite kubva kuvagadziri vanogona kutaura zvakananga nezvehuwandu hwezviyo uye kuwanikwa kwematombo, kwete kungoona CTE chete kubva mubhuku rekushandisa.
Chinyorwa Chinoshanda kubva Pakukuya Pasi
Tinochengeta makamuri edu anodzora tembiricha nehunyoro nekuda kweizvi - kwete kunyanya kunyaradzwa, asi nekuti kukuya nekuongorora kwekupedzisira kunoitwa patembiricha yakagadzikana, inozivikanwa zvinogadzira zvinhu zvine humbowo hwekusatsetseka hunochengetedza kana vabuda muchivako. Vatengi vanovaka mapuratifomu ekuongorora e semiconductor kana zvivakwa zveCMM, kanopfuura kamwe, vakatikumbira kuti tinyore tembiricha yemhepo panguva yekuyera kwekupedzisira uye tiiise pamwe chete nesitifiketi chekusatsetseka, kuitira kuti timu yavo yemetrology ive nenzvimbo yakanyorwa yekutarisa kubva gare gare.
Kuwedzera kwekupisa mugranite hakusi dambudziko rinofanira kugadziriswa zvachose - ichinhu chaicho chinofanira kutarisirwa, nenzira imwecheteyo iyo kudedera kana hunyoro zvinofanira kutarisirwa nayo. Vagadziri nemarabhoritari vanoiona sechinhu chinozivikanwa, pane kufunga nezvekupedzisira kana chiyero chaonekwa chisina kunaka, vanowanzo pedza nguva shoma vachitevera zvikanganiso zvepfungwa izvo zvisiri zvechokwadi nezvechishandiso chacho.
