I-SMC (iSheet Molding Compound) isetyenziswa kakhulu kwimveliso yanamhlanje ngenxa yeempawu zayo ezintle ezifana nobunzima obulula, amandla aphezulu kunye nokumelana nokugqwala. Nangona kunjalo, kwimveliso yokwenyani kunye nokusetyenziswa kwayo, iziphene zangaphakathi zemicroscopic zezinto zihlala zichaphazela umgangatho wemveliso. Kutshanje, sifumene iisampulu zezinto zeSMC ezineziphene ezithunyelwe ngumthengi. Xa zidityaniswe neesampulu zeSMC ezifakiweyo, siza kuhlela kwaye sichaze ngokweenkcukacha iinkqubo zokulungiselela iisampulu ze-metallographic zobungcali kunye nenkqubo yonke yokujonga imicroscopic, sikunike isikhokelo esisebenzayo kakhulu sohlalutyo lwemicroscopic lwezinto ezidityanisiweyo.
Ukusika imizekelo: Isixhobo sovavanyo se-SMC esineziphene zokuqhekeka sisikwa ngokuchanekileyo ngumatshini wokusika we-metallographic. Ngexesha lokusebenza, isantya sokusika kunye nesantya sokutya zilawulwa ngokungqongqo ukuze kuthintelwe umonakalo wesibini kwindawo eqhekekileyo ebangelwa luxinzelelo loomatshini. Okwangoku, umphezulu wokusika uqinisekiswa ukuba uthe tyaba kwaye awunazo iziqwenga ukuze kuhlangatyezwane neemfuno zokulungiselela isampuli elandelayo.
Ukulungiselela Ukufakelwa Okubandayo: Beka isampuli esikiweyo ngokuchanekileyo kwisikhunta sokufaka se-cold mounting press, uze ugalele kancinci i-cold mounting resin. Qinisekisa ukuba i-resin iyigquma ngokupheleleyo indawo eqhekekileyo kunye nommandla ojikelezileyo wesampuli ngaphandle kwamaqamza okanye imingxuma. Yivumele ime kubushushu begumbi ide i-resin inyangeke ngokupheleleyo kwaye yenziwe, uguqula isampuli ibe yibhloko eqhelekileyo efakelweyo ukuze kube lula imisebenzi elandelayo yokugaya nokupolisha.
Ukusila nokuPolisha iisampuli: Isampuli efakwe ebandayo neyomileyo ifakwa ekugayweni ngokulandelelana kunye nokucolwa kakuhle ngomatshini wokugaywa nokucolwa kwe-metallographic. Kwinqanaba lokugaywa, amaphepha arhabaxa anobukhulu obahlukeneyo be-mesh asetyenziswa ngokulandelelana kohlaza oluhlayo. Amandla afanayo asetyenziswa kumphezulu wesampuli ngexesha lokusebenza ukususa kancinci kancinci amanqaku okusika. Emva kokugaywa, ilaphu lokupolisha elihambelanayo kunye nearhente yokupolisha ziyasetyenziswa ukuze zicolwe kakuhle de umphezulu wokujonga wesampuli ufikelele esipilini ngaphandle kokukrweleka, ukuqhekeka okanye ezinye iziphene.
Ukujonga ngeMicroscopic: Uhlalutyo lokuqhekeka kwezinto ze-SMC, imakroskopu yesinyithi ekumgangatho ophezulu inokubonelela ngemifanekiso ecacileyo neyahlukileyo. Beka isampulu elungiselelwe kakuhle kwisigaba semakroskopu yesinyithi, kwaye ulungise indawo yesigaba ukuze ulungelelanise ngokuchanekileyo indawo eqhekekileyo yesampuli kunye nelensi yemicroscope. Ngokulungisa ukwandiswa kwemakroskopu, jonga indawo yokuqhekeka, indlela yokusasazeka kweentanda kunye nesakhiwo esijikelezileyo se-microstructure inyathelo ngenyathelo ukusuka ekukhuleni okuphantsi ukuya ekukhuleni okuphezulu. Okwangoku, bhala imifanekiso kunye nedatha ngokupheleleyo, ukuze unike isiseko esichanekileyo se-microscopic morphology sohlalutyo olulandelayo lwezizathu zokuqhekeka kwezinto.
Ukuba unomdla kwezi zixhobo zokulungiselela iisampulu kunye ne-metallographic microscope, nceda ubone uluhlu lweemveliso kwaye uzive ukhululekile ukunxibelelana nathi ukuze ufunde okungakumbi ngazo.
