筛分 依据DIN EN ISO9000 ff对颗粒粒径进行分析

颗粒粒径分布影响固体材料的物理和化学性质。因此,对颗粒粒径分布的认识和监控是在对粉体和颗粒制品的质量控质中不可或缺的重要环节。如同以下几个例子所显示,稳定的产品质量只有在恒定的颗粒粒径分布的前提下才能得到保障:

  • 混凝土的硬度决定于水泥的颗粒粒径分布;
  • 巧克力的口感受所用可可粉的细度的影响;
  • 洗衣粉的松散(可抖落)度和溶解性决定于其基本材料的细度和颗粒形状。

The Basic Principles of Sieve Analysis

Many natural and manufactured materials occur in a disperse form, which means that they consist of differently shaped and sized particles. The particle size distribution, i.e. the number of particles of different sizes, is responsible for important physical and chemical properties.

Such as:
• mechanical bulk behavior
• surface reaction
• taste
• miscibility
• filtration properties
• conductivity
This list could be continued at great length. The examples clearly show how important it is to have a knowledge of the particle distribution, particularly within the context of quality assurance in the production of bulk goods. If the particle distribution changes during the manufacturing process then the quality of the finished product will also change. Only a continuous monitoring of the particle size distribution can guarantee a constant product quality.
