KuZHHIMG®, isu tine hunyanzvi mukugadzira zvikamu zvegranite zvine nanometer chaiyo. Asi kunyatsojeka kwechokwadi kunopfuura kushivirira kwekutanga kwekugadzira; kunosanganisira kusimba kwenguva refu kwechimiro uye kugara kwenguva refu kwechinhu chacho. Granite, ingave ichishandiswa mumabhesi emuchina chaiwo kana kuvaka kwakakura, inogona kukanganiswa nezvikanganiso zvemukati zvakaita semaburi madiki uye maburi. Kusakwana uku, pamwe chete nekumanikidzwa kwekupisa kwezvakatipoteredza, kunotungamira zvakananga kurarama kwenguva refu uye kuchengetedzeka kwechikamu.
Izvi zvinoda kuongororwa kwepamusoro, kusingakuvadzi. Kuyedza kweThermal Infrared (IR) kwave nzira yakakosha yekuedza granite (NDT), ichipa nzira inokurumidza, isingabatanidzi yekuongorora hutano hwemukati mayo. Pamwe chete neThermo-Stress Distribution Analysis, tinogona kupfuura kungowana zvikanganiso tobva tanzwisisa kukanganisa kwayo pakugadzikana kwechimiro.
Sainzi yekuona kupisa: Nheyo dzeIR Imaging
Kufungidzira kweThermal IR kunoshanda nekutora simba reinfrared rinobuda pamusoro pegranite uye kurishandura kuita mepu yekupisa. Kugoverwa kwekupisa uku kunoratidza zvisina kunanga hunhu hwethermophysical.
Pfungwa yacho iri nyore: zvikanganiso zvemukati zvinoshanda sekusagadzikana kwekupisa. Semuenzaniso, kuputika kana kuti gomba, zvinokanganisa kufamba kwekupisa, zvichikonzera mutsauko unoonekwa mukupisa kubva kune ruzha rwakapoteredza. Kuputika kunogona kuoneka semutsara unotonhorera (uchivhara kufamba kwekupisa), nepo nzvimbo ine maburi akawanda, nekuda kwekusiyana kwesimba rekupisa, inogona kuratidza nzvimbo inopisa iri panzvimbo imwe chete.
Zvichienzaniswa nemaitiro echinyakare eNDT akadai sekuongorora kwe ultrasound kana X-ray, IR imaging ine zvakanakira zvakasiyana:
- Kukurumidza Kuskena Nzvimbo Yakakura: Mufananidzo mumwe chete unogona kufukidza masikweya mita akati wandei, zvichiita kuti uve wakakodzera kuskena nekukurumidza zvinhu zvikuru zvegranite, zvakaita sematanda emabhiriji kana mibhedha yemuchina.
- Hazvibatanidzi uye Hazviparadzi: Nzira iyi haidi kubatana kwemuviri kana nzira yekubata, zvichiita kuti pasave nekukuvadzwa kwechipiri pamusoro pechinhu chacho.
- Kutarisa Kunochinja: Kunobvumira kubatwa kwemamiriro ekuchinja kwetembiricha panguva chaiyo, zvakakosha pakuona zvikanganiso zvinogona kukonzerwa nekupisa sezvazvinokura.
Kuvhura Muchina: Dzidziso yeThermo-Stress
Zvikamu zvegranite zvinopedzisira zvaita kuti kupisa kwemukati kuwedzere nekuda kwekuchinja-chinja kwekushisa kwekunze kana kuti mutoro wekunze. Izvi zvinodzorwa nenheyo dzethermoelasticity:
- Kusawirirana kweKuwedzera kweThermal: Granite idombo rakagadzirwa nesimbi. Madanho emukati mezvicherwa (akadai sefeldspar nequartz) ane ma coefficients akasiyana ekuwedzera kwethermal. Kana tembiricha ikachinja, kusawirirana uku kunotungamira mukuwedzera kusina kufanana, zvichigadzira nzvimbo dzakasimba dzekumanikidzwa kana kumanikidzwa.
- Mhedzisiro Yekudzvanya Kwemavanga: Mavanga akadai semavanga kana maburi anodzivirira kuburitswa kwedambudziko renzvimbo, zvichikonzera kushushikana kwakanyanya muzvinhu zviri pedyo. Izvi zvinoshanda senzira yekukurumidzisa kupararira kwevanga.
Kuenzanisa nhamba, kwakadai seFinite Element Analysis (FEA), kwakakosha pakuenzanisa njodzi iyi. Semuenzaniso, kana tembiricha ye20°C ichichinja-chinja (sekutenderera kwemazuva/husiku), granite slab ine muromo wakamira inogona kusangana nekumanikidzwa kwepamusoro kusvika 15 MPa. Zvichienderana nekuti simba rekumanikidzwa kwegranite rinowanzova pasi pe10 MPa, kumanikidzwa uku kunogona kukonzera kuti muromo ukure nekufamba kwenguva, zvichikonzera kuora kwechimiro.
Uinjiniya Huri Kushanda: Chidzidzo Chekuchengetedza
Muchirongwa chekugadzirisa chakaitwa munguva pfupi yapfuura nezve granite column yekare, thermal IR imaging yakabudirira kuona bhandi rinotonhora risingatarisirwi riri pakati pechikamu. Kuchera kwakatevera kwakaratidza kuti kusagadzikana uku kwaive mutswe wemukati wakatambanuka.
Kumwe kutevedzera thermo-stress kwakatangwa. Kutevedzera kwakaratidza kuti tension stress yakanyanya mu crack panguva yekupisa kwezhizha yakasvika 12 MPa, zvichipfuura zvine njodzi muganhu wechinhu chacho. Kugadziriswa kwaidiwa kwaive kupinza epoxy resin chaiyo kuti chigadzike. Kuongorora kweIR mushure mekugadzirisa kwakaratidza kuti tembiricha yakaenzana zvakanyanya, uye kutevedzera stress kwakaratidza kuti tension stress yakaderedzwa kusvika padanho rakachengeteka (pasi pe5 MPa).
Kutarisirwa Kwehutano Hwakanyanya
Kufungidzira kweThermal IR, pamwe chete nekuongorora kwakasimba kwekumanikidzwa, zvinopa nzira inoshanda uye yakavimbika yehunyanzvi yeStructural Health Monitoring (SHM) yezvivakwa zvakakosha zvegranite.
Remangwana renzira iyi rinoratidza kuvimbika uye otomatiki zviri nani:
- Kusanganiswa kweMulti-Modal: Kusanganisa data reIR nekuyedzwa kwe ultrasound kuti zvivandudze kurongeka kwehuwandu hwekudzika kwezvikanganiso uye kuongororwa kwehukuru.
- Kuongorora Kwakangwara: Kugadzira maalgorithms ekudzidza zvakadzama kuti aenzanise minda yekupisa neminda yekushushikana yakaedzwa, zvichigonesa kupatsanurwa otomatiki kwezvikanganiso uye kuongororwa kwengozi yekufanotaura.
- Masisitimu eIoT Anoshanduka: Kubatanidza masensa eIR netekinoroji yeIoT yekutarisa mamiriro ekupisa uye emakanika panguva chaiyo muzvivakwa zvakakura zvegranite.
Nekuziva zvikanganiso zvemukati zvisingapindiki uye kuyera njodzi dzinobatanidzwa nekupisa, nzira iyi yepamusoro inowedzera hupenyu hwechikamu, ichipa vimbiso yesainzi yekuchengetedza nhaka uye kuchengetedzeka kukuru kwezvivakwa.
