Moetso oa ente ea phofo ea Micro metalmokhoa: MIM tšepeho bopa ente ea phofomokhoa ke thekenoloji e sebelisang motsoako oa phofo e ntle ea tšepe le resin kapa boka (binder) e le lisebelisoa tse tala bakeng sa ho bopa ka ente ea tšepe ebe e senya (ho senya sekontiri) le sintering ho hlahisa lihlahisoa tsa tšepe. , Ke mokhoa oa ho etsa lintho tse ngata o kopanyang phofo ea metallurgy le ho bopa ente ea polasetiki. E ka sebelisa phofo e ntle ea tšepe ho fetaphofo ea metallurgy, kahoo e ka khothalletsa sintering ho hlahisa lisebelisoa tse phahameng, 'me ts'ebetso ea sehlahisoa e ntlafatsoa haholo. E ka boela ea etsa likaroloana tse nyenyane tsa tšepe tse nang le libopeho tse rarahaneng le ho nepahala ho holimo. Haufinyane tjena, mokhoa oa ho bopa ente ea phofo ea micro metal o ntlafalitsoe ka katleho.
TheMoetsi oa MIMe na le melemo e mehlano e latelang:
- Phofo e ntle ea tšepe le binder e khethoa ho theha likarolo, 'me thepa e tala e na le metsi a mangata.
- The homogenization ea likheo tse tala e lemohuoa ka ho kopanya le granulating.
- Tšebeliso ea theknoloji ea ho etsa hlobo ea tšepe ea microporous e ntlafalitse ho tlatsoa ha thepa, botsitso ba ho bopa, ho lokolloa ha hlobo le thepa ea ho tsamaisa.
- Lebelo la ho futhumatsa le eketseha nakong ea ts'ebetso ea debinding le sintering, e ka laolang kholo ea lijo-thollo tsa kristale le ho thibela deformation le tšenyo nakong ea shrinkage.
- Theknoloji e nepahetseng ea tlhahlobo e thehiloe ts'ebetsong ea tlhahlobo.
Ts'ebetso ea ho bopa ente ea tšepe
Theknoloji ea ho bopa e sa tsoa etsoa ea "resin" e entsoeng ka "resin" e entsoeng ka tšepe ea phofo e sebelisa hlobo ea resin e kentsoeng ka har'a hlobo ea tšepe ho theha 'mele oa ho qetela o entsoeng ke mochini oa ente ea phofo ea tšepe,' me qetellong o hlakoloe le ho siling. Le ho felisa. Theknoloji ena e ka thibela hantle tšenyo ea 'mele o bōpiloeng' me ho bonolo ho e tšoara.
Ha ho bapisoa le lisebelisoa tsa porous tse thehiloeng ho polymer, moetsi oa tšepe oa tšepe o entsoeng ka tšepe o na le ho hanyetsa mocheso o motle le thepa ea mochine. Ha li bapisoa le lisebelisoa tsa ceramic, ha li na ductility e ntle feela, empa hape li na le motlakase o phahameng le mocheso oa mocheso. E lebelletsoe ho sebelisoa haholo litsing tse fapaneng tsa li-filters, Li-catalysts tsa Chemical reaction, li-exchanger tsa mocheso, li-absorber tsa matla, jj.
MIM (Metal Injection Molding) e sebetsa mefuteng e mengata ea lisebelisoa tsa tšepe tse kenyelletsang tšepe e tlase ea alloy, tšepe e sa hloekang, tšepe ea lisebelisoa, li-alloys tse thehiloeng ho nickel, alloy ea tungsten, carbide, titanium, lisebelisoa tsa makenete, alloy ea Kovar le lirafshoa tse ntle, joalo-joalo.Amohela potso!
