Isu tinoshandisa makuki kuwedzera ruzivo rwako.Nekuramba uchitsvaga webhusaiti ino, unobvuma kushandisa kwedu makuki.Mamwe mashoko.
Chinyorwa chinobva kuPolymer Testing magazini inoongorora uye inoenzanisa mhando yezvakati wandei zvepolymer composite zvinhu zvinogadzirwa uchishandisa 3D yekutsikisa tekinoroji, senge morphology uye pamusoro pemasikirwo, michina zvivakwa, uye zvinopisa zvinhu.
Tsvagiridzo: Nano-particle-yakapinza zvigadzirwa zvepurasitiki zvakagadzirwa ne3D maprinta anotungamirwa nekudzidza muchina.Mufananidzo kunobva: Pixel B/Shutterstock.com
Izvo zvinogadzirwa zvepolymer zvikamu zvinoda hunhu hwakasiyana zvichienderana nechinangwa chazvo, zvimwe zvacho zvinogona kupihwa nekushandisa polymer filaments inoumbwa nehuwandu hwakasiyana hwezvinhu zvakawanda.
Bazi rekuwedzera kugadzira (AM), inonzi 3D kudhinda, tekinoroji yekucheka-kumucheto inosanganisa zvinhu kugadzira zvigadzirwa zvichibva pane 3D modhi data.
Nokudaro, tsvina inogadzirwa nenzira iyi iduku.3D tekinoroji yekudhinda ikozvino inoshandiswa mumhando dzakasiyana-siyana, kusanganisira hukuru hwekugadzira zvinhu zvakasiyana-siyana, uye huwandu hwekushandisa huchawedzera chete.
Iyi tekinoroji ikozvino inogona kushandiswa kugadzira zvinhu zvine zvimiro zvakaomarara, zviremu zvezvinhu, uye zvigadziriso zvinogoneka.Pamusoro pezvo, kudhinda kwe3D kune zvakanakira kushanda zvakanaka, kusimba, kuita zvakasiyana-siyana uye kuderedza njodzi.
Chimwe chezvakanyanya kukosha zveiyi tekinoroji zvinosanganisira kusarudza maparamita akakodzera nekuti ane simba guru pachigadzirwa, senge chimiro, saizi, kutonhora, uye gradient yekupisa.Aya hunhu anobva akanganisa kushanduka kweiyo microstructure, maitiro ayo uye hurema.
Kudzidza kwemuchina kunogona kushandiswa kumisikidza hukama pakati pemamiriro ekuita, microstructure, chimiro chechikamu, kuumbwa, kukanganisa, uye mhando yemakina echimwe chigadzirwa chakadhindwa.Izvi zvinongedzo zvinogona kubatsira kudzikisira huwandu hwemiyedzo inodiwa kuburitsa yemhando yepamusoro.
High-density polyethylene (HDPE) uye polylactic acid (PLA) ndiwo maviri anonyanya kushandiswa mapolymers muAM.PLA inoshandiswa sechinhu chikuru chezvishandiso zvakawanda nekuti inogadzikana, ine mari, inoodza uye ine zvivakwa zvakanaka.
Plastic recycling inyaya huru yakatarisana nenyika;saka, zvingave zvinobatsira zvikuru kubatanidza purasitiki inogona kushandiswa zvakare mu 3D kudhinda maitiro.
Sezvo zvinyorwa zvinodhinda zvichiramba zvichiiswa mu liquefier, tembiricha inochengetwa padanho rinoenderana panguva ye fused filament kugadzira (FFF) deposition (rudzi rwe 3D kudhinda).
Naizvozvo, iyo polima yakanyungudutswa inoburitswa kuburikidza nemhuno nekudzikiswa kwekumanikidza.Surface morphology, goho, kurongeka kwejometri, zvivakwa zvemuchina, uye mutengo zvese zvinokanganiswa neFFF.
Tensile, compressive impact kana kukombama simba uye dhinda kutungamira zvinoonekwa seakanyanya kukosha maitiro akasiyana anobata FFF samples.Muchidzidzo ichi, nzira yeFFF yakashandiswa kugadzira zvienzaniso;nhanhatu dzakasiyana filaments dzakashandiswa kugadzira sampuli layer.
a: ML yekufungidzira parameter optimization modhi yemaprinta e3D mumasample 1 ne2, b: ML prediction parameter optimization modhi yemaprinta e3D mumuenzaniso 3, c: ML prediction parameter optimization modhi yemaprinta e3D mumasample 4 ne5. Kunobva mufananidzo: Hossain , MI, nezvimwewo.
3D kudhinda tekinoroji inogona kusanganisa yakanakisa mhando yemapurojekiti ekudhinda ayo asingagone kuwanikwa nenzira dzechinyakare dzekugadzira.Nekuda kweiyo yakasarudzika nzira yekugadzira ye3D kudhinda, mhando yezvikamu zvakagadzirwa zvinokanganiswa zvakanyanya nedhizaini uye maitiro akasiyana.
Kudzidza kwemuchina (ML) kwakashandiswa munzira dzakawanda mukuwedzera kugadzira kusimudzira budiriro yese uye maitiro ekugadzira.Iyo data-yakavakirwa yepamusoro dhizaini nzira yeFFF uye hurongwa hwekugadzirisa FFF chikamu dhizaini yakagadziridzwa.
Vatsvagiri vakafungidzira tembiricha yenozzle nerubatsiro rwemazano ekudzidza muchina.ML tekinoroji inoshandiswawo kuverenga tembiricha yemubhedha wekudhinda uye kumhanya kwekudhinda;saizi yakafanana inotarwa kune ese masampuli.
Mhedzisiro yacho inoratidza kuti kuyerera kwechinyorwa kunokanganisa zvakananga kunaka kweiyo 3D inodhinda kubuda.Chete tembiricha yakakodzera yenozzle inogona kuve nechokwadi chekuyerera kunodiwa kwezvinhu.
Mubasa iri, PLA, HDPE uye zvakadzokororwa filament zvinhu zvakasanganiswa neTiO2 nanoparticles uye inoshandiswa kugadzira yakaderera-mutengo 3D yakadhindwa zvinhu nekutengeserana yakanyungudutswa filament kugadzira 3D maprinta uye filament extruders.
Iwo mafilamendi ehunhu inyowani uye anoshandisa graphene kugadzira isingapindi mvura, iyo inogona kuderedza chero shanduko mune yakakosha mekiniki zvimiro zvechigadzirwa chakapedzwa.Kunze kweiyo 3D yakadhindwa chikamu chinogona zvakare kugadziriswa.
Chinangwa chikuru chebasa iri kutsvaga nzira yekuwana yakavimbika uye yakapfuma mekiniki uye yemuviri mhando mu 3D yakadhindwa zvinhu zvichienzaniswa neyechinyakare 3D yakadhindwa zvinhu zvinowanzogadzirwa.Mhedzisiro uye mashandisirwo eiyi tsvakiridzo anogona kuvhura nzira yekuvandudzwa kwezvirongwa zvakawanda zvine chekuita neindasitiri.
Ramba uchiverenga: Ndeapi nanoparticles akanakira ekuwedzera kugadzira uye 3D kudhinda maapplication?
