Tsanangudzo Pfupi

NdFeB mhete magineti zvakare inoshandiswa zvakanyanya mumusika ine akawanda akasiyana maapplication.

Matanho edu ekugadzira: batching - kunyungudika - kugadzirwa kwehupfu - kudzvanya - sintering - kukuya pamusoro - kugadzira (gomba kugadzirisa, kucheka ...) - chamfering - electroplating - magnetizing - kurongedza.

Yedu yekuendesa nguva: sampuli yekugadzira kutenderera 10-15 mazuva, misa yekugadzira kutenderera 20-25 mazuva.

Zvakanakira: Iyo inonyanya kudhura-inoshanda, kukurumidza kuburitsa, nyore kuunganidza.

Chishandiso: Mhete yeNdFeB inoshandiswa zvakanyanya mune hollow cup mota, vacuum cleaner mota, hair dryer mota, gudzanzwi nemamwe minda.Mumashandisirwo emota, ine yakakwira zvakanyanya kudiwa pane magineti geometric dimension uye magineti midziyo, iyo shoma yekushivirira inogona kunge iri mukati me 0-0.03mm. Mukushandisa gudzanzwi, magineti anowanzo kuve neZn coating, kuendesa pasi pe-un-magnetized mamiriro, giredhi remagineti senge. N, M uye H akatevedzana giredhi, kazhinji gudzanzwi magineti haadi giredhi repamusoro.Imwe application ndeyemusika wekushongedza, tiri kupa mamirioni zvimedu mhete magineti kune vatengi vedu pasi rese, magineti anoshandiswa kurongedza bhokisi, axial magnetized. kana multipole axial magnetized akafanana 2 kana 4 matanda, uye kwete chete yakachena magineti, tiri zvakare avaialbe mamwe magineti musangano.

Zvigadzirwa zvakagadziridzwa: Yedu mhete magineti inogona kugadzirwa kubva 3mm-200mm yekunze dhayamita, 1mm-150mm yemukati dhayamita, ukobvu kubva 1mm-70mm. Inodawo kupfekedzwa nguva zhinji, seNiCuNi, Zn, Epoxy zvichingodaro...
