spherical alumina poda
Product Description
Spherical alumina chinhu chepamusoro-chinoshanda chine kuchena kwepamusoro, spherical particles, kuomarara kwepamusoro, kushomeka kwepamusoro, kushomeka kwepamusoro, kugadzikana kwemafuta uye kunaka kwemagetsi.Spherical alumina ine kuoma kwakanyanya uye simba, izvo zvinoita kuti ive yakakodzera kupfeka-inodzivirira zvinhu.Muminda yekeramics, zvemagetsi, indasitiri yemakemikari uye kuvaka, spherical alumina inoshandiswa zvakanyanya mukugadzirwa kwemhando yepamusoro ceramic zvinhu, advanced kupfeka-resistant bearings, advanced automotive engine parts, etc. Spherical alumina ine high corrosion resistance, iyo inoita kuti ikwanise chengetedza kushanda kwakagadzikana munzvimbo dzakaoma.Semuenzaniso, munharaunda yeMarine, indasitiri yemakemikari, indasitiri yemagetsi uye mamwe minda, spherical alumina inoshandiswa mukugadzira ngarava, makemikari emidziyo, midziyo yemagetsi uye zvichingodaro.Spherical alumina ine yakanaka kugadzikana kwemafuta uye kuvharirwa kwemagetsi, kuitira kuti igone kuchengetedza kuita kwakanakisa mukupisa kwepamusoro uye kudzvanywa kwenzvimbo.Mumunda wemagetsi, spherical alumina inoshandiswa mukugadzira-yepamusoro-tembiricha zvigadzirwa zvemagetsi, yakakwira-voltage magetsi emagetsi, nezvimwe.

Product Features
Kuzadza Kwakakwirira: Yakakwira dhigirii ye spheroidization chiyero, inodzoreka particle saizi kugovera, kuwana yakakwira density kuzadza kwesilicone uye epoxy resin, kuwana musanganiswa ine yakaderera viscosity uye yakakwirira kufamba;
Yakakwira Thermal Conductivity: Nekuda kweiyo inenge yakakwana bhora dhizaini, iyo yekuzadza inoshandiswa mune yakabikwa inogona kuwana akawanda-directional kupisa kutapurirana.Iyo yese yakasanganiswa sisitimu iri mumamiriro ekupararira kwakanaka, saka zvigadzirwa zvekupedzisira zvine yakanakisa yekupisa conductivity uye pfuma yemuviri;
Yakaderera Abrasion: Kuenzaniswa nehupfu husina kurongeka, kushandiswa kwespherical filler kunogona kuderedza abrasion yemusanganisi, michina yekuumba uye zvimwe zvishandiso, wozorebesa hupenyu hwekushanda hwemidziyo yakakodzera.
