Iindaba

Kwintsimi yemveliso yemizi-mveliso yanamhlanje,izixhobo zokulungisa i-powderIdlala indima ebalulekileyo kwaye isetyenziswa kakhulu kumashishini amaninzi afana nokulungiselela umgubo wesinyithi, amayeza, kunye nokulungiswa kokutya. Kumashishini, kubalulekile ukukhetha izixhobo ze-atomization zomgubo ezihlangabezana neemfuno zawo zemveliso. Oku akuchaphazeli nje kuphela umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso, kodwa kukwanxulumene kakhulu nolawulo lweendleko. Oku kulandelayo kuza kuchaza amanqaku aphambili kunye namanyathelo okukhetha ezo zixhobo.

1.Cacisa iimfuno zemveliso

(1) Iimpawu zomgubo

Okokuqala, kuyimfuneko ukumisela ngokuchanekileyo iimpawu zepowder efunekayo. Kubandakanya ukusasazwa kobukhulu be-powder particles, ingaba ifuna ii-micron ezincinci nezilinganayo okanye ii-nanometer powders, okanye ii-particles ezirhabaxa; Imilo yepowder, efana ne-spherical okanye i-irregular, inomahluko omkhulu ekubunjweni nasekusebenzeni kwemveliso elandelayo; Kukwakho neemfuno zococeko lweekhemikhali kwi-powders, eziphantse zibe ngqongqo kwiindawo eziphezulu ezifana neyeza kunye ne-elektroniki, ngelixa ezinye izicelo zoshishino ngokubanzi zibanzi ngokwemigaqo yococeko. Umzekelo, xa kuprintwa iindawo zesinyithi ze-3D, kudla ngokufuneka ukuba kusetyenziswe ii-metal powders ezine-sphericity ephezulu kunye nokusasazwa kobukhulu be-particles obuncinci ukuqinisekisa uxinano kunye neempawu zoomatshini zeendawo eziprintiweyo; Ekuveliseni ii-coatings eziqhelekileyo, iimfuno ze-powder shape ziguquguquka, kwaye ukusasazwa kobukhulu be-particles okubanzi kunokwanelisa iimfuno.
