铝银浆也称为铝粉浆,银浆等,主要成分是雪花状的铝颗粒和石油溶剂,通常为糊状。 好的铝银浆的区别特征主要在于:铝板表面光滑平整,粒径分布集中,形状规则,光反射能力强,金属光泽。 当区分铝银浆的使用寿命时,可以通过铝银浆的“跟随效应”原理来识别。 当铝银浆与透明彩色颜料混合时,会引起漆膜反应。

铝颜料

  铝银浆的各种特性可以通过其生产工艺来确定,并且出于安全性考虑,几乎所有现代铝银浆都通过湿法在溶剂中研磨。

  首先将原材料熔融喷涂,以获得纯度不低于99.7%(根据EN576标准)的不规则喷涂粉末。 然后将其在球磨机添加的润滑剂下,在溶剂中研磨成片状颗粒。 研磨参数和润滑剂类型取决于颜料的用途。

  研磨后,将颜料悬浮液过筛,过滤并混合,以获得固体含量为65%且溶剂为35%的产物。 通过向滤饼中添加特定的溶剂或添加特殊的添加剂,可以根据不同的应用生产合适的颜料产品。

  Summary

  Aluminium paste are used in the paints and coatings industry both for their appearance and to fulfil certain functions. Special-effect pigments are always in the form of flakes and particle diameter is larger than that of colour pigments. While the particle size of colour pigments is in the wavelength range of visible light, The flake diameter of special effect pigments is generally around 5-100um.

  The properties of Aluminium paste can be deduced directly from the production process,

  But for reasons of safety modern Aluminium paste are produced almost exclusively using the a wet milling process.

  The raw material is atomized, Irregular powder with a minimal purity of 99.7% according to EN 576 which is milled or shaped into flake-like particles in ball mills in white spirit in the presence of a lubricant.

  The milling parameters and the lubricant are determined by the application for which the pigment is intended. The pigment suspension produced after milling is screened, pressed on filter presses and mixed in mixers to the standard combination of 65% solids and 35% solvent.The final product can be adapted for its later application by the addition of a special solvent or by adding special additives to the filter cake.
