Kev tsis

Alumina sib tsoo cov pob. Nws yog hais txog kev siv Bauxite, cov menyuam hmoov, alumina calci Nws yog tsuas yog siv rau sib tsoo xov thiab tuaj yeem siv dav siv, thiab tseem tuaj yeem muab faib ua nruab nrab cov khoom thiab cov khoom muaj zog txhuas raws li cov ntsiab lus ntawm Alumina.

Sib tsoo meding yog cov khoom lossis cov thooj voos kheej kheej uas yob hauv lub pob zeb. Cov xov xwm sib tsoo ntawm cov pob zeb zoo tib yam yog tsuas yog cov khoom hlau thiab thooj voos kheej kheej, thaum nyob hauv kev lag luam ntau lawm ceramic. Lub ntsiab siv yog ceramic sib tsoo me - ua raws li los ntawm ntuj flint thiab pebbles. Nyob rau tam sim no, cov xov xwm sib tsoo ceramic tau teev nyob hauv peb lub teb chaws tsuas muaj xws li Alumina, zirconium oxide thiab lwm koob. Alumina tej hub npas yog cov khoom tseem ceeb engineering ceramics thiab yog cov khoom lag luam siab.

Nta

Alumina tej yam cov yam ntxwv muaj cov yam ntxwv ntawm cov hardness, ceev, hnav tsis kam, corrosion tsis kam thiab tus nqi tsawg. Cov pob hlau muaj cov teeb meem ntawm cov hlau immurities, yog li alumina tej khoom pob ceramic yog qhov zoo sib tsoo hauv nruab nrab. Nyob rau hauv lub tsev ceramics kev lag luam, kev coj ua tau zoo ntawm alumina cov khoom pob yog 2O ~ {{s siab dua li ntawm ntuj flint thiab pebbles.
