一种化学品氢氧化铝的制备方法
摘要：
一种化学品氢氧化铝的制备方法，涉及一种用于实体面材填料的化学品氢氧化铝制备方法。其特征在于将种分氢氧化铝和磨制后的干白氢氧化铝收尘料，进行混合配制而获得。本发明的制备方法简单合理，容易实施，特别是有效利用了干白氢氧化铝生产过程中产生的附加值低的收尘料，利用其结构不完善、可磨磨性好的特点，与种分氢氧化铝混合配制，制备出了用作实体面材填料的化学品氢氧化铝，其粒度D50在17-21um，并且具有亮度高，粘度低的特点，经客户使用，加入此种氢氧化铝填料后，加工流动性提高，固化时间缩短，实体面材的机械性能提高，同时树脂耗用量也得到减少。
摘要（英）：

The invention relates to a preparation method of a chemical aluminum hydroxide, particularly a preparation method of a chemical aluminum hydroxide for solid face material fillers. The method is characterized by comprising the following step: mixing graded aluminum hydroxide and a ground dry white aluminum hydroxide dust collection material to obtain the chemical aluminum hydroxide. The preparation method is simple and reasonable, is easy to implement, and especially effectively utilizes the low-added-value dust collection material generated in the dry white aluminum hydroxide production process; and the dust collection material is mixed with the graded aluminum hydroxide by using the characteristics of incomplete structure and favorable grindability to prepare the chemical aluminum hydroxide used as a solid face material filler. The particle size D50 is 17-21 mu m. The chemical aluminum hydroxide has the characteristics of high brightness and low viscosity. When in use of customers, after the aluminum hydroxide filler is added, the processing flowability is enhanced, the curing time is shortened, the mechanical properties of the solid face material are enhanced, and the resin consumption is reduced.
