Similar hardness white fused alumina, white fused alumina than in the high toughness, abrasive cutting edge sharp edges cners to keep good, high durability. 硬度与白刚玉相近,韧性则比白刚玉高,磨粒切削刃锋利,棱角保持性好,耐用度较高。
The white alumina abrasives made with vitrified bond may show red in white, red-yellow or celadon-gray. This will influence on the appearance quality of the products seriously. 陶瓷结合剂白刚玉磨具会出现白里显红、红黄、青灰色调,严重影响产品的外观质量。
The single particle strength of nano alumina abrasive and conventional white alumina, imported SG abrasives was contrasted. 并将制备的纳米刚玉磨料的单颗粒强度与白刚玉和国外SG磨料进行了对比。
From inner to outside, the composite pipe consisted of alumina ceramic layer, metal transition layer, white cast layer, carbon atom diffusion layer and nodular cast iron layer. 复合管从里到外由氧化铝陶瓷层、金属过渡层、白口铸铁层、碳原子扩散层、球墨铸铁层组成。
From the results it could be found that the kaolinite as a mineral substance was mainly contained in the Fengfeng high alumina clay and white clay, but the CaO and K_2O contents of white clay result from retention of small amount of calcite and muscovite. 从所得结果发现峰峰坩石和白坩土中所含主要矿物组成为高岭石类矿物,而白坩土中所含CaO和K2O是若干量的碳酸钙和白云母等矿物的残留所形成。
It was found that the sintering temperature of porous alumina ceramic membrane support was reduced from 1600 ℃ to 1300 ℃ assisted with commercial titanium white powder ( rutile). 研究发现,在商业钛白粉(主要成分为金红石型氧化钛)的反应助烧作用下,多孔氧化铝陶瓷膜支撑体的烧结温度由通常的超过1600℃降到1300℃。
The project extracts alumina by sulfuric acid from coal fly ash, the surplus silicon dioxide were made into white carbon black. So that the project can realize the use which is uncontaminated and have additional value. 本项目以粉煤灰为原料,采用酸法提取氧化铝,提取氧化铝后的二氧化硅制备白炭黑,实现粉煤灰的无污染高附加值利用。
