I-SMC (i-Sheet Molding Compound) isetshenziswa kabanzi ekukhiqizeni kwezimboni zesimanje ngenxa yezakhiwo zayo ezinhle kakhulu njengesisindo esincane, amandla aphezulu kanye nokumelana nokugqwala. Kodwa-ke, ekukhiqizweni nasekusetshenzisweni kwangempela, amaphutha angaphakathi amancane kakhulu ezinto ezibonakalayo avame ukuthinta ikhwalithi yomkhiqizo. Muva nje, sithole amasampula ezinto ze-SMC anephutha athunyelwe yikhasimende. Uma sihlanganiswe namasampula e-SMC alethiwe, sizohlunga futhi sichaze ngokuningiliziwe izinqubo zokulungiselela isampula ye-metallographic yobungcweti kanye nenqubo yonke yokubuka nge-microscopic, sikunikeze umhlahlandlela owusizo kakhulu wokuhlaziywa nge-microscopic kwezinto ezihlanganisiwe.
Ukusikwa Kwesifanekiso: Ingxenye yokuhlola ye-SMC enezinkinga zokuqhekeka isikwa ngokunembile ngumshini wokusika we-metallographic. Ngesikhathi sokusebenza, ijubane lokusika kanye nesilinganiso sokudla kulawulwa ngokuqinile ukuze kugwenywe umonakalo wesibili endaweni eqhekekile okubangelwa ukucindezeleka komshini. Okwamanje, indawo yokusika iqinisekiswa ukuthi iyisicaba futhi ayinayo i-burr ukuze kuhlangatshezwane nezidingo zokulungiselela isampula okulandelayo.
Ukulungiselela Ukufakwa Okubandayo: Beka isampula esinqunyiwe ngokunembile esikhumbeni sokufaka se-cold mounting press, bese uthela kancane i-cold mounting resin. Qinisekisa ukuthi i-resin imboza ngokuphelele indawo eqhekekile nendawo ezungezile yesampula ngaphandle kwamabhamuza noma izikhala. Yivumele ime endaweni yokushisa yegumbi kuze kube yilapho i-resin ipholile ngokuphelele futhi yakheka, uphendule isampula ibe yibhulokhi evamile efakwe ukuze kube lula ukusebenza okulandelayo kokugaya nokupholisha.
Ukugaya Nokupholisha Izibonelo: Isampula efakwe emakhazeni futhi elashwe ifakwa ekugayweni okulandelanayo kanye nokupholishwa kahle ngomshini wokugaya nokupholishwa kwe-metallographic. Esigabeni sokugaya, amaphepha akhuhlayo anobukhulu obuhlukene be-mesh asetshenziswa ngokulandelana kwegrit ehlayo. Amandla afanayo asetshenziswa ebusweni besampula ngesikhathi sokusebenza ukuze kususwe kancane kancane amamaki okusika. Ngemva kokugaya, indwangu yokupholishwa ehambisanayo kanye ne-ejenti yokupholishwa kusetshenziswa ukuze kupholishwe kahle kuze kube yilapho ubuso bokubuka besampula bufinyelela esibukweni ngaphandle kokuklwebheka, ukugoba noma ezinye iziphambeko.
Ukuqaphelwa Okuncane: Ukuze kuhlaziywe ukuqhekeka kwezinto ze-SMC, i-microscope ye-metallurgical esezingeni eliphezulu ingaletha izithombe ezicacile nezingafani. Beka isampula elungiselelwe kahle esiteji se-microscope ye-metallurgical, bese ulungisa indawo yesiteji ukuze uvumelanise kahle indawo eqhekekile yesampula nelensi ye-microscope. Ngokulungisa ukukhuliswa kwe-microscope, qaphela indawo yokuqhekeka, isiqondiso sokusabalala kwe-crack kanye nesakhiwo se-microstructure esizungezile isinyathelo ngesinyathelo kusukela ekukhulisweni okuphansi kuya ekukhulisweni okuphezulu. Okwamanje, qopha izithombe nedatha ngokuphelele, ukuze unikeze isisekelo esinembile se-microscopic morphology sokuhlaziywa okulandelayo kwezimbangela zokuqhekeka kwezinto.
Uma unesithakazelo kulezi zixhobo zokulungiselela amasampula kanye ne-metallographic microscope, sicela ubheke uhlu lwemikhiqizo futhi uzizwe ukhululekile ukuxhumana nathi ukuze ufunde kabanzi ngazo.
