  铝银浆的形状

  将具有不规则形状的雾化颗粒磨碎或撞击后,由于金属的可延展性,它们被加工成薄片,形成系数(厚度与直径的比)为1:50〜1:200。

  粒子形状可以是不规则的(雪花型)或接近圆形的(银元型)。 银元型铝银浆具有优异的光学性能。 它们通过非常精细的加工技术,以特殊且非常精细的喷雾粉制造而成。

  片状颜料的统计厚度取决于产品和研磨技术,即颜料颗粒不是单分散的,而是具有一定粒度和厚度统计分布的异质分散体系。

  金属颜料的粒径分布对光学性能具有决定性的影响,因此要进行质量控制,但片状颜料的各向异性也给这项工作带来了困难。

  shape of Aluminum paste

  The ductile nature of the metals used means that milling or crushing of the irregular atomized powder in the ball mill creates flakes with shape factors (flake thickness: flake diameter) of 1:50 to 1:200.

  Particle shape varies from irregular flakes (cornflakes ) to almost completely round particles(silver dollars). Silver dollars Aluminium paste generation and have excellent optical properties. They are produced in an extremely elaborate process using special, very fine granulates.

  Statistical particle thickness can vary depending on the product and the milling technology used, i.e. the various pigments are not monodisperse particles but heterodisperse systems with a more or less statistical distribution of particle sizes and thicknessess.

  Particle size distribution in metallic pigments has a decisive influence on the optical properties of the applications. It is essential, therefore, to measure particle size distribution for quality control and in order to classify the pigments, the anisotropy of the flakes makes this difficult however.
