Wax is immiscible in the water making it difficult to form an emulsion. This can be handled by use of surfactants and by various emulsifying processes. The methods can be categorized as chemical, electrochemical, physical, physiochemical, or biological.
The two immiscible liquids wax, and water are mixed in mixers and then homogenised in a colloid mill.
Particle size distribution of the emulsion becomes the key factor when the process of mixing two immiscible liquids is spoken about. First, there is a need to increase the amount of energy used in the mixing process that may help reduce particle sizes and thereby create a more stable and uniform emulsion. Obtaining a consistent and homogenized mixture with nearly identical particle size becomes critical.
The turbulent forces generated in the UADA reactor shears droplet sizes and particles of the various medium inclusive of additives, forcing them to become a homogenized mixture and stay in suspension for longer periods of time with tight and uniform micrometre sized particle distribution.
Using the UADA module, homogenized stable and ultra-fine dispersions with identical particle size are obtained with less to no surfactants being required making it an energy and cost-effective method.
