Résumé : |
With a powder wetting machine light filler materials such as expanded and expandable microspheres can be easily inducted and dispersed dust and loss free.
This saves cost and can produce products with improved properties.
Light filler materials are always applied when it is required to reduce the weight of coatings.
In addition, certain light fillers can facilitate the application, shorten drying times, vary the haptics of coated surfaces and cause some matting effect. On the other side, these light fillers are very dusty and difficult to wet and disperse. Its extremely low specific weight and the high specific surface - which in extreme cases may exceed 100 000 m2/kg - use of conventional dispersing methods such as dissolvers or stirrers very often result in an ordeal or becomes a game of pure chance.
A special powder wetting and dispersing machine may eliminate this problem by dust and loss free handling of these light filler materials. the combination of a powder wetting machine and light filler materials provides a very high potential of rationalising as well as the possibility to produce systems with improved properties. |
