【报告】指甲油(氧化铁)配方研磨测试

Cosmetic 化妆品

Nail polish (iron oxide) 

指甲油(氧化铁)

medium viscosity 

中等粘度

good flowability 

流动性好

(pre-dispersed by customer) 

 该实验前，客户先对产品进行预分散

The customer would like to have a homogeneous product with a particle size < 10 μm. Initial particle size is 100 μm.

客户要求制成粒径大小< 10μm的匀质产品。产品的初始粒子大小是100μm。

By reducing the particle size it is possible to make a thinner layer of nail polish with a much better quality and opacity at the same time. The durability of the product increase as well with a thinner layer. Particles can be saved which leads to a cost reduction.

通过降低颗粒的粒径，使较薄的指甲油也能拥有更好的质量、不透明度及更好的耐久度。可以节省颜料用量，从而降低成本。

方法一：卧式砂磨机 

SL5-C: The product (300 ml) was filled into the 1l supply container of the SL5-C. The DISPERMAT® SL5-C runs 60 min in circulation mode with a speed of 3040 rpm (= 8 m/s). The bead size was 0.4 – 0.6 mm (ZrO2 beads) with a filling ratio of 80% (=40 ml).

将300mL产品装进SL5-C配备的1L容器里。DISPERMAT®SL5-C 在循环模式下运行60分钟且转速为3040 rpm(相当于线速度为 8 m / s)。研磨珠的粒径为0.4 - 0.6 mm (氧化锆珠)且填充率为80% (= 40ml)。

方法二：篮式砂磨机

 CV3 Plus + TML0.5: Here, the product (428 ml) was filled into a 0.5 l double walled container and was grinded 60 min with the TML system at 3250 rpm (= 8 m/s). There were 0.4 – 0.6 mm ZrO2-beads used with a filling ratio of 70% (= 28 ml). A 40 mm dissolver disc supports the product flow.

将428mL产品倒进0.5L的水浴双壁杯内，并在3250 rpm (相当于线速度为8 m/s)转速下用TML研磨系统研磨60分钟。其中研磨系统装有0.4 - 0.6mm 氧化锆研磨珠且填充率为70% (= 28 ml)。根据此产品的流动情况配合使用40mm研磨盘。

在此案例中，可得出：

1.用篮式砂磨机研磨60分钟后，物料细度可由100μm下降到小于4μm，而用

卧式砂磨机只能下降到小于10μm，可见，在研磨相同时间和物料的情况下，篮式砂磨机比卧式砂磨机研磨效率更高。

2.篮式砂磨机比卧式砂磨机更能有效地控制研磨所产生的热量，保持低温。
