Sefa yeCeramic Foam: Magadzirirwo Epamusoro-soro & Mashandisirwo Ekugadzira Zvigadzirwa zveIndasitiri

Mafirita eCeramic Foam (CFF) zvinhu zvakakosha pakusefa zvinopisa zvakanyanya kumaindasitiri emazuva ano ekugadzira simbi nesimbi. Aine chimiro chakasiyana che3D chakabatana nemasero akavhurika, anobvisa zvinobudirira tsvina kubva musimbi yakanyungudutswa, anodzikamisa kuyerera kwemvura, uye anovandudza zvakanyanya kunaka kwekusefa uye goho rezvigadzirwa. Nekugadzikana kwakanaka kwekupisa, kuramba ngura kwemakemikari uye simba rakasimba remakanika, mafirita eceramic foam ave mhinduro inosarudzwa yekuchenesa simbi yakanyatsogadzirwa pasi rese.

Tinopa mafirita efoam eceramic akajairwa uye akagadzirwa zvinoenderana nemamiriro akasiyana-siyana ekuumbwa kwemaindasitiri. Zvinhu zvitatu zvikuru zviripo: alumina, silicon carbide uye zirconia. Mafirita eAlumina akanakira kuumbwa kwealuminium alloy patembiricha yakaderera. Mafirita eSilicon carbide anodzivirira kupisa kusvika 1560°C, akakodzera kuumbwa kwemhangura uye kugadzirwa kwesimbi patembiricha yepakati. Mafirita eZirconia anopa simba rekudzivirira kukurwa kwevhu, akagadzirirwa simbi yakachena uye simbi isina tsvina. Mafirita edu anofukidza saizi yakakwana yepore kubva pa10 PPI kusvika 60 PPI. Mamodheru e10–20 PPI anopa mwero wepamusoro wekuyerera kwema ingots makuru, 20–30 PPI inoenzanisa kunyatsojeka uye kushanda zvakanaka kwekugadzira billet nguva dzose, uye mafirita e30–60 PPI ultra-fine anobvisa tsvina diki yekugadzirwa kweporeti-wall. Zvigadzirwa zvese zvinochengetedza 75%–85% yakakwira kuti ive nechokwadi chekuti simbi inoyerera zvakanaka uye kushanda kwakasimba kwekusefa.

Zvakagadzirwa munzvimbo dzakaoma dzekushanda, maCFF edu ane simba guru rekudzivirira kupisa uye anodzivirira simbi yakanyungudutswa. Haakonzere kusvibiswa kwechipiri uye anochengetedza chimiro chakasimba pasi pekushanda kwakasimba. Zvinoenderana nekukanda jecha, kukanda mold zvachose uye kukanda mari, mafirita aya anogona kuiswa mumabhazi ekudira, marunners nemasprues kuti simbi icheneswe zvakanaka.

Dzinoshandiswa zvakanyanya mukugadzira simbi yesimbi ine ferrous neisina ferrous, mafirita edu anochenesa aruminiyamu yakanyungudutswa yezvikamu zvemotokari, zvikamu zvemuchadenga uye maprofile ezvivakwa. Anobvisa maoxide kubva mumhangura nemhangura kuti awedzere kufambiswa kwemagetsi, nepo mamodheru esilicon carbide ne zirconia ane simba guru achinatsa simbi yakanyungudutswa kuti ive nezvikamu zvemakanika zvine hungwaru uye zvinogara kwenguva refu.

Mafirita emhando yepamusoro eceramic foam anoderedza zvikanganiso zvekukanda zvinhu zvakaita semaburi uye slag inclusions, anoderedza mitengo yezvimedu uye anoderedza mari yekugadzira.Mitemo yeISO, mafirita edu anopa mashandiro akasimba uye akavimbika ekugadzira zvinhu zvakawanda, zvichibatsira mafekitori kusimudzira maitiro uye kuvandudza mabhenefiti ehupfumi.

Tinopa mhinduro dzehunyanzvi dzakagadzirwa zvichienderana nezvinhu zvenyu zvekukanda, mamiriro ekushanda uye zvinodiwa zvechigadzirwa. Rutsigiro rwekugadzirisa zvinhu zvisiri zvemhando yepamusoro uye maodha akawanda ane zvinhu zvakakwana uye kutumirwa kwakasimba.
