E-ZHHIMG®, sisebenza ngokukhethekileyo ekwenzeni amacandelo e-granite ngokuchaneka kwe-nanometer. Kodwa ukuchaneka kokwenyani kudlulela ngaphaya kokunyamezelana kwemveliso yokuqala; ibandakanya ukuthembeka kwesakhiwo sexesha elide kunye nokuqina kwempahla ngokwayo. Igranite, nokuba isetyenziswe kwiziseko zoomatshini ezichanekileyo okanye ulwakhiwo olukhulu, ichaphazeleka kwiziphene zangaphakathi ezinje nge-micro-cracks kunye ne-voids. Oku kungafezeki, kudityaniswe noxinzelelo lwe-thermal yokusingqongileyo, kuyalela ngokuthe ngqo ixesha elide kunye nokhuseleko lwecandelo.
Oku kufuna uvavanyo oluphambili, olungangeneleliyo. I-Thermal Infrared (IR) Imaging iye yavela njengendlela ebalulekileyo yoVavanyo lwe-Nondestructive Testing (NDT) yegranite, ebonelela ngeendlela ezikhawulezayo, ezingadibanisiyo zokuvavanya impilo yayo yangaphakathi. Idityaniswe noHlahlelo lwe-Thermo-Stress Distribution, sinokuhamba ngaphaya kokufumana isiphene ukuze siqonde ngokwenyani ifuthe laso kuzinzo lwesakhiwo.
ISayensi yokubona ubushushu: Imigaqo yokuCinga i-IR
I-Thermal IR imaging isebenza ngokubamba amandla e-infrared aphuma kumphezulu wegranite kwaye uwaguqulele kwimephu yobushushu. Oku kusasazwa kweqondo lokushisa ngokungangqalanga kubonisa iimpawu eziphantsi ze-thermophysical.
Umgaqo uqondile: iziphene zangaphakathi zisebenza njenge-anomalies ye-thermal. Ngokomzekelo, i-crack okanye isithuba sithintela ukuhamba kobushushu, nto leyo ebangela ukuba kubekho umahluko obonakalayo kwiqondo lobushushu kwisixhobo sesandi esijikelezileyo. Ukuqhekeka kunokubonakala njengokupholileyo (ukuthintela ukuhamba kobushushu), ngelixa indawo enemingxuma ephezulu, ngenxa yomahluko kumthamo wobushushu, inokubonisa indawo eshushu yendawo.
Xa kuthelekiswa neendlela eziqhelekileyo ze-NDT ezifana nokuhlolwa kwe-ultrasonic okanye i-X-ray, i-imaging ye-IR ibonelela ngeenzuzo ezahlukileyo:
- Ukuskena okuKhawulezayo, okukuMmandla oMkhulu: Umfanekiso omnye unokugubungela iimitha ezininzi zesikwere, uwenze ulungele ukujongwa okukhawulezileyo kwezinto ezinkulu zegranite, ezinje ngemiqadi yebhulorho okanye iibhedi zoomatshini.
- I-Non-Contact kunye ne-Nondestructive: Indlela ayifuni ukudityaniswa komzimba okanye ukudibanisa okuphakathi, ukuqinisekisa umonakalo wesibini we-zero kwindawo ecocekileyo yecandelo.
- I-Dynamic Monitoring: Ivumela ukuthatyathwa kwexesha lokwenyani leenkqubo zokutshintsha ubushushu, kubalulekile ekuchongeni iziphene ezinokuthi zibe kho ngenxa ye-thermal njengoko zikhula.
Ukuvula iMechanism: Ithiyori yeThermo-Stress
Amacandelo e-Granite aphuhlisa ngokungenakuthintelwa uxinzelelo lwangaphakathi lwe-thermal ngenxa yokuguquguquka kweqondo lokushisa okanye imithwalo yangaphandle. Oku kulawulwa yimigaqo ye-thermoelasticity:
- IMismatch yoKwandiswa kweThermal: IGranite lilitye elihlanganisiweyo. Izigaba zangaphakathi zamaminerali (ezifana ne-feldspar kunye ne-quartz) zinee-coefficients zokwandiswa kwe-thermal ezahlukeneyo. Xa amaqondo obushushu etshintsha, oku kungafaniyo kukhokelela kulwandiso olungafaniyo, ludala iindawo ezixineneyo zoxinzelelo okanye olucinezelayo.
- Impembelelo yokuNqanda isiphene: Iziphene ezifana neentanda okanye iipores ngokwendalo zinyanzelela ukukhululwa koxinzelelo lwasekhaya, okubangela uxinzelelo oluphezulu kwizinto ezikufutshane. Oku kusebenza njenge-accelerator yokusasazwa kokuqhekeka.
Ukulinganisa kwamanani, njengeFinite Element Analysis (FEA), kubalulekile ukulinganisa lo mngcipheko. Umzekelo, phantsi kobushushu obujikelezayo obungama-20°C (njengomjikelo wemini/ubusuku obuqhelekileyo), isilabhu segranite esinesiqhekeza esithe nkqo sinokuba namava oxinzelelo oluphezulu olufikelela kwi-15 MPa. Ngenxa yokuba amandla okuqina egranite ahlala engaphantsi kwe-10 MPa, olu xinzelelo lunokubangela ukuba ukuqhekeka kukhule ngokuhamba kwexesha, okukhokelela ekuwohlokeni kwesakhiwo.
Ubunjineli obuSebenzayo: Uphononongo lokuGcinwa
Kwiprojekthi yokubuyisela yamva nje malunga nekholamu yamandulo yegranite, umfanekiso oshushu we-IR ichonge ngempumelelo ibhanti ebandayo yonyaka ebingalindelekanga kwicandelo eliphakathi. Ukugrunjwa okulandelayo kwaqinisekisa ukuba oku kuphambana kukuqhekeka okuthe tye kwangaphakathi.
Imodeli eyongezelelweyo ye-thermo-stress yaqaliswa. Ukulinganisa kubonise ukuba uxinzelelo oluphezulu lwe-tensile ngaphakathi kokuqhekeka ngexesha lobushushu behlobo lufikelele kwi-12 MPa, ngokuyingozi ngaphezu komda wezinto eziphathekayo. Ukulungiswa okufunekayo kwakuyi-injection epoxy resin echanekileyo ukuzinzisa isakhiwo. Ukuhlolwa kwe-IR emva kokulungiswa kuqinisekisile indawo yokushisa efanayo ngokuphawulekayo, kunye nokulinganisa uxinzelelo kuqinisekisile ukuba uxinzelelo lwe-thermal luncitshiswe kwi-threshold ekhuselekileyo (ngaphantsi kwe-5 MPa).
