Ukukhethwa kwezibophelelo zesinyithi somgubo,iteknoloji yokubumba inaliti yomgubo wesinyithiyimveliso yokudityaniswa kunye nokudibana kobuchwepheshe bokubumba iplastiki, ikhemistri yepolymer, ubuchwepheshe besinyithi somgubo kunye nesayensi yezixhobo zetsimbi. Umngundo unokusetyenziselwa ukutofa ukubumba into engenanto kwaye uyidlulise kwi-Sintering inokuvelisa ngokukhawuleza ubuninzi obuphezulu, obuchanekileyo, obuchanekileyo, obunxantathu obunobume obunobume obuntsonkothileyo. Iyakwazi ukukhawuleza kwaye ngokuchanekileyo ifake iingcamango zoyilo kwiimveliso ezineempawu ezithile zesakhiwo kunye nokusebenza, kwaye inokuvelisa ngokuthe ngqo iindawo ezininzi. Lutshintsho olutsha kushishino lweteknoloji yokuvelisa.
Iimpawu zenkqubo:
Le teknoloji yenkqubo ayinayo kuphela inzuzo yeenkqubo zesinyithi zentsimbi eziqhelekileyo ezifana namanyathelo ambalwa, akukho okanye ngaphantsi kokusika, kunye neenzuzo eziphezulu zoqoqosho, kodwa ziphinde zoyise iintsilelo zemveli.iimveliso zomgubo wesinyithinjengezinto ezingalinganiyo, iimpawu eziphantsi zomatshini, kunye nobunzima bokwenza iindonga ezincinci kunye nezakhiwo ezinzima. Kufanelekile ngokukodwa ukuveliswa kobuninzi bezinto ezincinci, eziyinkimbinkimbi kunye nezikhethekileyo zetsimbi. Uqukuqelo lwenkqubo: isibophelelo → ukuxuba → ukubumba isitofu → ukukhupha igrisi → ukucola → ukusetyenzwa kwasemva.
Umgubo wentsimbi:
Ubungakanani besuntswana lomgubo wesinyithi osetyenziswa kwiInkqubo yeMIMngokubanzi yi-0.5 ~ 20μm; ithiyori, i-fineral particles, inkulu indawo ethile yomhlaba, okwenza kube lula ukumila kunye ne-sinter. Inkqubo yemveli yomgubo wesinyithi isebenzisa umgubo orhabaxa omkhulu kuno 40μm.
Kwi-Mim ye-Mim ye-metal, i-binder idlala indima ebaluleke kakhulu, ichaphazela ngokuthe ngqo ukuxuba, ukubumba, ukubumba, ukuchithwa kunye nezinye iinkqubo, kwaye kunempembelelo enkulu kumgangatho, ukuhlambalaza kunye nokuchaneka kwe-dimensional ye-metal powder injection yokubumba ingenanto, ukwakheka kwe-alloy, njl. umatshini, oko kukuthi, uba ngumthwali wokuqhuba ukuhamba komgubo. Ngoko ke, ukhetho lwe-binder luyisitshixo ekubunjweni kwenaliti yonke ye powder. Iimfuno zesibophelelo:
- imali encinci, oko kukuthi, ukuqinisekisa ukuba umxube une-rheology engcono ngelixa usebenzisa i-binder encinci kangangoko kunokwenzeka;
- Akukho mpendulo, okt akukho reaction yamachiza kunye nomgubo wesinyithi;
- Kulula ukususa, akukho ntsalela kwimveliso.
Umphefumlo we-binder powder metallurgy inkqubo ye-MIM, ukongezwa kunye nokususwa kwayo iteknoloji ephambili ye-MIM, kunye nenkqubo yokunciphisa isetyenziswe kwinkqubo yokubopha iyinhloko yophando lwesihloko ekhaya nakwamanye amazwe. Izibophelelo ezisetyenziswa kwi-MIM ziquka iinkqubo ze-thermoplastic, iinkqubo ze-thermoset, iinkqubo ze-soluble zamanzi, iinkqubo ze-gel kunye neenkqubo ezikhethekileyo, nganye ineenzuzo zayo kunye nokungalunganga. Inkqubo yokubopha i-Thermoplastic yeyona nto iphambili kunye ne-precursor ye-MIM binder, kwaye abantu bagxile ekuphuculeni iimpawu zerheological zokutya okuziinkozo, Uphando oluninzi luye lwenziwa ukunciphisa ukuguqulwa kwe-degreasing kunye nokunciphisa ixesha lokunciphisa, kwaye ezinye ii-arhente ezikhethekileyo ezibandakanya izibophelelo ze-polyacetal ziye zaphuhliswa. Kodwa uphando kunye nophuhliso lwezibophelelo alukho nge powders
Ubudlelwane, ukuxuba umgubo kunye nezibophelelo, iipropati zerheological kunye ne-thermodynamic zezibophelelo kunye nokutya phantsi kweemeko ezahlukeneyo,Impembelelo yezibophelelo kwi-degreasing kunye neempawu zemveliso zibonelela ngemigaqo yendalo yonke kunye nesiseko sethiyori yokukhethwa kwezibophelelo, ngokungathandabuzekiyo eyodwa Inentsingiselo entle kakhulu. Uphuhliso lwenkqubo entsha nesebenzayo yokudibanisa isixokelelwano ikwayingqwalaselaItekhnoloji yeMIM.
