操作指南

水性铝浆的使用方式与传统铝浆大致相同。为了达到理想的分散效果并充分展现包括白度、金属感、遮盖力、着色力、鲜映度(DOI)及随角异色性的的各种金属颜料的特性,我们建议以1:1或1:2的比例把铝浆预先分散在适当的溶剂,即水、乙二醇丁醚、丙二醇甲醚或异丙醇当中。

When using our aluminium pigment pastes for aqueous systems the same general recommendations apply as for conventional aluminium pastes. To achieve the optimum pigment dispersion and develop the full potential charateristics of the metallic pigment,brightness, brilliance, coverage and tinting strength distinctiveness of image (DOl, flop (two tone)we recommend predispersing the aluminium pigment paste in suitable solvents,i.e.- water, butyl glycol, methoxypropanol, isopropanol in a proportion 1.1 or 1: 2

同时,建议把溶剂逐渐加到铝颜料浆中,并不断搅拌。添加溶剂之后,可以继续搅拌该混合浆,以确保完全分散。此外,如果在使用前先把颜料/溶剂混合浆放置一段时间,可能可以获得更理想的效果。需要注意的是,搅拌叶应尽量靠近调浆桶的底部,以保证颜料浆完全分散。搅拌叶的直径应为调浆桶直径的1/2到3/4。

At the same time it is recommended to gradually add the solvent to the aluminium pigment paste whilst stirring constantly. Upon completion of the solvent addition, the slurry may be stirred more thoroughly to ensure complete dispersion. In addition, some benefits may be observed upon holding the pigment/solvent slurry for a period of time before any further processing is done. Please note the mixing blade should be close to the bottom of the mixing vessel in order to ensure complete dispersion of the pigment paste.The diameter of the mixing blade should be 1/2 to 3/4 the diameter of the mixing vessel.


推荐工序如下:

Following is a recommended procedure

A.先把铝颜料添加至调浆桶中,然后添加溶剂,要时添润湿剂

B.完全搅拌后,检查是否有未分散的颜料存在

C.彻底搅拌后,可添加配方中的其它成分

-First add the aluminium pigment to the mixing vessel,then add solvent and if necessary-a wetting agent.

-After thorough mixing, check for any undispersed pigment

-After thorough mixing has been achieved, other formulation components may be added.


添加适当的润湿剂或分散剂可获得更理想的分散效果。

Addition of suitable wetting or dispersing agent can be beneficial.

铝浆可与多种阴离子、阳离子与非离子乳化剂相容。

Aluminium pigment pastes are compatible with a variety of anionic, cationic and nonionic emulsifiers.


无论是在溶剂型还是水性涂料体系中,都应该避免使用过高的剪切力而导致过高的机械应力。高剪切力可能导致片状颜料的变形和碎裂。颜料的损坏会直接影响外观特性、发气稳定性和最终产品的储存稳定性。

In both solvent and waterborne coating systems, extensive mechanical stress due to high shear forces should be avoided. High shear may result in deforming and/or fracturing of the pigment particles. This damage will reduce the optical properties, gassing stability and overall shelf life of the product.


因此我们建议使用低剪切力的搅拌叶,并根据调浆桶的尺寸来调节搅拌叶的直径(见前述)。建议的搅拌速度为500-800rpm。此外,影响铝颜料涂料表现的因素还有pH值以及用于调整pH值的添加剂。它们都会影响产品的储存期限和发气稳定性。

Low shear mixing blades are recommended, their diameters have to be adjusted to the size of the mixing vessel(see above) Suggested mixing speed for dissolver blades is 500-800 rpm. Other parameters determining the performance of the aluminium pigmented coating material are the pH-value and the additives for adjustment of the pH-value in the coating material that influence shelf life and gassing stability. 


根据我们的经验,当涂料的pH值介于6-9时,下列颜料都有令人满意的稳定性。

According to our own experience, coatings with a pH-range between 6-9 can be produced with sufficient stability .


然而,以上的限制仍取决于所使用的树脂体系。因此无论是在生产还是开发过程中,测试和控制发气都非常重要。

However these limits are dependent on the binder system used and therefore testing and control of gassing is very important in both development and manufacture .


任何情况下,在与颜料预分散浆混合之前,树脂体系都应调节至正确的pH值。当选择适合的添加剂,如氢氧化铵(氨水)、TEA、DMEA、AMP90、TMEA等调节pH值时,应注意在发气稳定性上,氢氧化铵(氨水)或TEA会比DMEA或AMP90带来大的不良影响。

In all cases the binder system has to be adjusted to the correct pH-value before blending with the aluminium paste slurry. When choosing suitable additives for the adjustment of the pH-value such as Ammonium Hydroxide, TEA, DMEA, AMP 90, TMEA and others, it should be considered that products like Ammonia or TEA have a more disadvantageous influence on the gassing stability than e. g DMEA or AMP 9O.
