Electric corundum A14一级棕刚玉微粉金刚砂320#360#
Electric corundum A14一级棕刚玉微粉金刚砂320#360#的主要成分是氧化铝,它是以铝矾土为原料,无烟煤,铁霄,在电弧中经2000度以上高温熔炼制成。然后经过磨机粉碎整形,磁选去铁,筛分成多种粒度,其质地致密、硬度高,韧性好。棕刚玉微粉的粒度分级是水洗溢流、自然沉淀烘干,纯净度更高,粒度范围窄无大颗粒,适合研磨抛光。
The main component of brown corundum is aluminum oxide, which is made from bauxite as raw material, anthracite, and iron oxide. It is melted at high temperatures above 2000 degrees in an electric arc. Then, it is crushed and shaped by a mill, magnetically selected to remove iron, and screened into various particle sizes. Its texture is dense, hardness is high, and toughness is good. The particle size classification of brown corundum micropowder is water washing overflow, natural precipitation drying, higher purity, narrow particle size range, and no large particles, suitable for grinding and polishing.
Electric corundum A14一级棕刚玉微粉金刚砂320#360#特点:
1. 棕刚玉韧性比白刚玉高,适合研磨金属件。
2. 棕刚玉微粉经过磁选和水洗,杂质少,无金属残留,研磨后不会产生锈斑。
3. 经过水力分级,粒度均匀,粒径范围窄。
4. 成本比其他研磨微粉低。
Features:
1. Brown corundum has higher toughness than white corundum and is suitable for grinding metal parts.
2. Brown corundum powder undergoes magnetic separation and water washing, with minimal impurities and no metal residue. After grinding, it will not produce rust spots.
3. After hydraulic grading, the particle size is uniform and the particle size range is narrow.
4. The cost is lower than other grinding powders.
