Kugadzirira Tekinoroji yeAlumina Ceramics (1)

Kugadzirira kwehupfu

Alumina powderinogadzirirwa kuita poda zvinhu zvinoenderana neyakasiyana chigadzirwa zvinodiwa uye akasiyana ekuumba maitiro.Hukuru hwehupfu huri pasi pe1μm.Kana zvichidikanwa kugadzira yakakwira kuchena alumina ceramic zvigadzirwa, mukuwedzera kune kuchena kwealumina kunofanirwa kudzorwa mu99.99%, inodawo kuita ultrafine kugaya maitiro kuita yayo particle size yekugovera yunifomu.

Paunenge uchishandisa extrusion molding kana jekiseni kuumba, binder uye epurasitiki mumiriri anofanira kuunzwa muupfu, kazhinji muhuremu reshiyo ye10-30% thermoplastic purasitiki kana resin, organic binder inofanira kusanganiswa nealuminium poda pa150-200 ℃ tembiricha zvakaenzana. kuitira kufambisa basa rekuumba.

Zvigadzirwa zvehupfu zvakaumbwa nekupisa kudzvanya maitiro hazvidi kuwedzera binder.Kana kushandisa semi-otomatiki kana otomatiki yakaoma kuomesa kuumba, pane yakakosha tekinoroji zvinodiwa zvehupfu, isu tinofanirwa kushandisa pfapfaidzo granulation nzira yekurapa upfu, ita kuti iite seyakatenderera, kuitira kuvandudza fluidity yehupfu, nyore. kuzadza mold wall otomatiki mukuumba.Kupfapfaidza granulation yehupfu inodiwa panguva yakaoma yekutsikirira, uye polyvinyl doro rinounzwa sebinder.Mumakore achangopfuura, sangano rekutsvagisa muShanghai rakagadzira parafini inonyungudika nemvura sechinhu chinosungirira kupfapfaidza granulation yeAl2O3, ine mvura yakanaka pasi pekudziya.Iyo poda mushure mekupfapfaidza granulation inofanirwa kuve nekuyerera kwakanaka, yakasununguka density, kuyerera Angle friction tembiricha isingasviki 30 ℃, yakanakira particle size reshiyo uye mamwe mamiriro, kuitira kuti uwane yakakwira density yeyakajeka girinhi.

Molding nzira

Nzira dzekuumba dzealumina ceramic zvigadzirwainosanganisira yakaoma kudzvanya, grouting, extrusion, inotonhora isostatic kudzvanya, jekiseni, kuyerera kukanda, kupisa kudzvanya uye kupisa isostatic kudzvanya.Mumakore achangopfuura kumba nekune dzimwe nyika kwakagadzirawo dhizaini yekuumba, yakananga kusimba jekiseni kuumba, gel jekiseni kuumba, centrifugal jekiseni kuumba uye yakasimba yemahara yekuumba yekuumba tekinoroji nzira.Maumbirwo akasiyana, saizi, maumbirwo akaomarara uye nemazvo ezvigadzirwa zvinoda nzira dzakasiyana dzekuumba.
