PaZHHIMG®, isu tinonyanya kugadzira zvikamu zvegranite zvine nanometer chaiyo. Asi kunyatsojeka kwechokwadi kunowedzera kupfuura kwekutanga kushivirira kwekugadzira; inopindirana nekugara kwenguva refu kwemaitiro uye kusimba kwechigadzirwa chacho. Granite, ingave yakashandiswa mumabhesi emuchina chaiwo kana kuvaka-hombe, inotapukirwa nekukanganisika kwemukati senge micro-cracks uye voids. Izvi zvisina kukwana, zvakasanganiswa nemamiriro ekunze ekupisa kushushikana, zvinoraira zvakananga hupenyu hurefu hwechikamu uye chengetedzo.
Izvi zvinoda kuongororwa kwepamusoro, kusingapindiki. Thermal Infrared (IR) Imaging yakabuda seyakakosha Nondestructive Testing (NDT) nzira yegranite, ichipa kukurumidza, isiri-yekubata nzira yekuongorora hutano hwemukati. Yakabatana neThermo-Stress Distribution Analysis, tinogona kupfuura kungotsvaga chikanganiso kuti tinyatsonzwisisa mhedzisiro yacho pakugadzikana kwechimiro.
Sayenzi yeKuona Kupisa: IR Imaging Principles
Thermal IR imaging inoshanda nekubata infrared simba rinovhenekerwa kubva pamusoro pegranite uye kurishandura kuita mepu yetembiricha. Uku kugovera tembiricha zvisina kunanga kunoratidza zviri pasi pe thermophysical properties.
Nheyo yacho yakananga: kuremara kwemukati kunoshanda seanomalies yekupisa. Kutsemuka kana kusavapo, semuenzaniso, kunotadzisa kuyerera kwekupisa, zvichiita kuti pave nemusiyano unooneka wetembiricha kubva paruzha rwakatenderedza. Mutswe unogona kutaridzika semutsetse unotonhorera (kuvharira kupisa kuyerera), nepo nzvimbo ine nyuchi zvakanyanya, nekuda kwekusiyana kwekupisa, inogona kuratidza nzvimbo inopisa.
Kuenzaniswa neyakajairwa NDT matekiniki senge ultrasonic kana X-ray yekuongorora, IR imaging inopa akasiyana mabhenefiti:
- Kurumidza, Yakakura-Nzvimbo Kuongorora: Mufananidzo mumwechete unogona kuvhara akati wandei mativi metres, uchiita kuti ive yakanakira kukurumidza kutariswa kwezvinhu zvakakura zvegranite, senge matanda ebhiriji kana mibhedha yemuchina.
- Isiri-Contact uye Nondestructive: Iyo nzira haidi kubatanidza kwemuviri kana yepakati, kuve nechokwadi che zero kukuvara kwechipiri kune pristine pamusoro pechikamu.
- Dynamic Monitoring: Inobvumira kutora-chaiyo-nguva yekutora tembiricha maitiro ekuchinja, kwakakosha pakuona zvingangove zvinokonzereswa ne thermally hurema pavanenge vachikura.
Kuvhura iyo Mechanism: Iyo dzidziso yeThermo-Stress
Zvikamu zvegranite zvinosimudzira kusagadzikana kwekupisa kwemukati nekuda kwekushanduka kwekushisa kwemukati kana mitoro yekunze. Izvi zvinodzorwa nemisimboti ye thermoelasticity:
- Thermal Kuwedzera Mismatch: Granite idombo rakaumbwa. Yemukati mineral phases (senge feldspar uye quartz) ine akasiyana ekuwedzera kupisa kwemafuta coefficients. Kana tembiricha ikachinja, kusawirirana uku kunotungamira kune kusiri-uniform kuwedzera, kugadzira nzvimbo dzakasimba dzekutemesa kana kudzvinyirira.
- Defect Constraint Effect: Kukanganisika senge makatsemuka kana ma pores anogara achimanikidza kuburitswa kwenzvimbo kushushikana, zvichikonzera kushushikana kwakanyanya muzvinhu zviri padyo. Izvi zvinoshanda seanomhanyisa kuparadzira crack.
Numerical simulations, senge Finite Element Analysis (FEA), yakakosha pakuenzanisa njodzi iyi. Semuyenzaniso, pasi pe cyclic tembiricha inotenderera ye20°C (semazuva ese/husiku kutenderera), granite slab ine vertical crack inogona kusangana nepamusoro pesimba rinosvika 15 MPa. Tichifunga kuti kusimba kwegranite kunowanzo kuve kushoma pane gumi MPa, uku kushushikana kwepfungwa kunogona kukonzera kuti mutswe ukure nekufamba kwenguva, zvichitungamira mukuparara kwechimiro.
Injiniya Mukuita: Nyaya Yekudzidza Mukuchengetedza
Mune ichangoburwa purojekiti yekudzoreredza ine chekuita nekoramu yekare yegranite, inodziya IR imaging yakabudirira kuona isingatarisirwe annular inotonhora bhendi muchikamu chepakati. Kuchera kwakatevera kwakaratidza kusanzwisisika uku kwaive kutsemuka kwemukati kwakachinjika.
Imwezve thermo-stress modelling yakatangwa. Iyo simulation yakaratidza kuti peak tensile stress mukati mekuputika panguva yekupisa kwezhizha yakasvika 12 MPa, zvine njodzi kupfuura muganhu wezvinhu. Kugadziriswa kwaidiwa kwaive kwakanyatsojeka epoxy resin jekiseni kudzikamisa chimiro. Yekumashure-kugadzirisa IR cheki yakasimbisa yakanyanya kufanana tembiricha yemunda, uye kudzvinyirira simulation kwakasimbisa kuti kushushikana kwekupisa kwakaderedzwa kusvika padanho rakachengeteka (pazasi pe5 MPa).
Iyo Horizon yeAdvanced Health Monitoring
Thermal IR imaging, yakasanganiswa nekuomarara kushushikana kwekuongorora, inopa inoshanda uye yakavimbika tekinoroji nzira yeStructural Health Monitoring (SHM) yeakakosha granite zvivakwa.
Remangwana reiyi nzira inonongedza kune yakawedzera kuvimbika uye otomatiki:
- Multi-Modal Fusion: Kubatanidza IR data ne ultrasonic bvunzo kuti uvandudze huwandu hwechokwadi hwekuremara kudzika uye saizi yekuongorora.
- Intelligent Diagnostics: Kugadzira yakadzika-yekudzidza algorithms yekubatanidza tembiricha minda ine yakateedzerwa kushushikana minda, ichigonesa iyo otomatiki kupatsanurwa kwehurema uye yekufungidzira njodzi yekuongorora.
- Dynamic IoT Systems: Kubatanidza IR sensors neIoT tekinoroji yekutarisa-chaiyo-nguva yekutarisa kwezvinopisa uye zvemakanika nyika mune yakakura-yakakura granite zvimiro.
Nekutadza kuona hurema hwemukati uye nekuenzanisa njodzi dzinosanganisirwa dzekushushikana kwemhepo, iyi nzira yepamusoro inowedzera zvakanyanya chikamu chehupenyu, ichipa vimbiso yesainzi yekuchengetedza nhaka uye kuchengetedzwa kukuru kwezvivakwa.
