摘要： A composition for polishing synthetic resin comprises a calcined alumina polishing agent and water. The polishing agent is prepared by burning boehmite, crushing it into particles and separating particles having a predetermined particle distribution. Also disclosed is a synthetic resin polishing composition further containing as a polishing accelerator an aluminum compound selected from among aluminum nitrate, polyaluminum chloride, aluminum bromide, aluminum sulfate, aluminum iodide, aluminum chloride and aluminum phosphate and mixtures thereof.
摘要翻译： 用于研磨合成树脂的组合物包括煅烧氧化铝抛光剂和水。 抛光剂是通过将勃姆石烧制而成，将其粉碎成颗粒并分离具有预定颗粒分布的颗粒。 还公开了一种合成树脂抛光组合物，其进一步含有选自硝酸铝，聚氯化铝，溴化铝，硫酸铝，碘化铝，氯化铝和磷酸铝的铝化合物作为抛光促进剂及其混合物。
