Zvigadzirwa
Upfu hwekupolisha hwearuminiyamu oxide hunoshandiswa pakupolisha pendi yemotokari
Upfu hweAlumina chinhu chakachena kwazvo, chakagadzirwa nealuminium oxide (Al2O3) chinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Upfu hwejena hwekristaro hunowanzo gadzirwa kuburikidza nekunatswa kwesimbi yebauxite.
Upfu hweAlumina hune zvinhu zvakawanda zvinodiwa, zvinosanganisira kuomarara kwakanyanya, kusabatwa nemakemikari, uye kudzivirira kupisa kwemagetsi, izvo zvinoita kuti huve chinhu chinokosha mumaindasitiri mazhinji.
Inowanzoshandiswa sezvinhu zvekugadzira zviumbwa zveceramics, refractories, uye abrasives, pamwe nekugadzira zvinhu zvakasiyana-siyana zvemagetsi, zvakaita se insulators, substrates, uye semiconductor components.
Mukurapa, upfu hwealumina hunoshandiswa mukugadzira mazino nezvimwe zvinoiswa mumafupa nekuda kwekushanda kwayo pamwe chete uye kuramba kwayo ngura. Hunoshandiswawo senzira yekupukuta mukugadzira magirazi emaziso nezvimwe zvinhu zvine chekuita nekugadzirwa kwemagirazi emaziso.
Kazhinji, upfu hwealumina chinhu chinoshandiswa zvakasiyana-siyana chinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekusanganiswa kwayo kwakasiyana kwehunhu hwepanyama nemakemikari.

1.Indasitiri yeCeramic:Upfu hweAlumina hunoshandiswa zvakanyanya sezvinhu zvakagadzirwa pakugadzira zviumbwa zvesimbi, zvinosanganisira zviumbwa zvesimbi zvemagetsi, zviumbwa zvesimbi zvinoramba kushanda, uye zviumbwa zvesimbi zvemhando yepamusoro.
2.Indasitiri yeKupukuta uye Kugadzira Zvinhu Zvisina Kunaka:Upfu hweAlumina hunoshandiswa sechinhu chinokwesha uye chinokwesha muzvinhu zvakasiyana-siyana zvakaita sema lenzi ekuona, ma wafer e semiconductor, uye pamusoro pesimbi.
3.Kugadzirisa:Upfu hweAlumina hunoshandiswa sechitsigiro chekusimudzira muindasitiri yemafuta ekugadzira zvinhu kuti huvandudze kushanda zvakanaka kwezvitsigiro zvinoshandiswa mukuchenesa.
4.Kuputira Kwemafuta Anopfapfaidza:Upfu hweAlumina hunoshandiswa sechishongo chekudzivirira ngura uye kusakara panzvimbo dzakasiyana-siyana muindasitiri yendege neyemotokari.
5.Kudzivirira Magetsi:Upfu hweAlumina hunoshandiswa sechishandiso chemagetsi chinodzivirira kupisa mumidziyo yemagetsi nekuda kwesimba rayo guru re dielectric.
6.Indasitiri yeRefractory:Upfu hweAlumina hunoshandiswa sechinhu chinodzivisa kupisa kwakanyanya, senge machira echoto, nekuda kwekunyunguduka kwayo kwakanyanya uye kugadzikana kwayo kwakanyanya pakupisa.
7.Chinowedzera muPolymers:Upfu hweAlumina hunogona kushandiswa sechinowedzera mumapolymers kuti huvandudze hunhu hwavo hwemakanika nekupisa.
