  铝银浆的分散

  使用时,先分散铝银浆和溶剂,铝银浆和溶剂的一般比例为1:2,在预分散时,涂料中添加的溶剂和铝银浆的量(见下图) ),缓慢混合后,缓慢搅拌后加入所选树脂,形成糊状。

  在分散过程中,为避免快速分散,应使用低速搅拌。 由于搅拌速度太快,它将产生高剪切力,破坏铝银浆的表面形状,从而导致闪光度下降。 好的分散速度应通过实验确定,因为它取决于许多因素和搅拌设备的几何形状(搅拌板,容器直径与容器直径之比,搅拌板的形状等)。 )油漆的温度和粘度。

  The Dispersion of Aluminum paste

  The ratio of aluminium paste to solvent should be about 1:1 to 1:2 (picture below shows concrete ratio), the solvent should be stirred slowly and gradually in to the paste and then add selective colophony.

  High mechanical sheer stress should be avoided when metallic pigments are dispersed. Stirrers (dissolvers) should be operated at a low speed as high shear forces can occur if stirring is too rapid. The ideal speed and duration of dispersion must be ascertained in tests, as the depend on a variety of factors, such as the geometry of the stirring equipment (ratio of stirrer diameter to container diameter, the shape of the stirrer), temperature, viscosity of the paint etc.

  安全事項

  铝银浆的稳定性能比铝粉安全,不易起火或爆炸,使用后立刻密封铝银浆容器,不及时盖好,溶剂很容易挥发,会导致氧化或增加起火的危险性。不要在有火源存在的环境中搬运、使用、存放本产品。一旦起火,请使用化学粉末或者耐火沙灭火。

  使用时,一旦皮肤接触铝银浆,立即用清水和肥皂徹底清洗干净。如果铝银浆进入眼睛,至少用清水洗15分钟,并请医生咨询。

  存放于室内铝银浆容器保持密封,存放温度在15-25°C, 避免直接暴露于阳光、雨水或者太大的湿度之中。

  在运输途中过分顛簸震动时,有可能导致铝银浆和溶剂的部分分离。使用时,应充分搅动均匀。

  处理废弃铝银浆只能在安全的地方并在授权人的监督之下少量销毁进行。

  Notice

  Aluminum paste has better stability than aluminum powder, not easy to be on fire or cause explosion. Container should be airproofed right after usage. If not, the solvent would volatilize, which will cause oxidation and increase fatalness of being on fire. Do not convey, use or storage products near fire. Once on fire, please use chemical powder or fire-resistant sand to put out the fire.

  Wash immediately with soap if touching Aluminum pastes. Once pastes go into the eyes, please wash with clean water for at least 1 5 minutes, and refer to the doctors.

  Store in indoor airproof container, temperature between 15 to 25,avoid direct exposal in sunlight, rainwater or high humidity.

  Partial separation of the Aluminum pastes and solvent might happen when jouncing. Please stire before use.

  Burning abandoned Aluminum pastes should only be allowed in secure places and under supervision of the corresponding authority.
