Fundamental approach

Background

•Experience indicates that soap-based emulsions shows improving cooling properties as the emulsion ages.

• NOA shows better cooling properties compared with soap-based emulsions. This is most likely related to the relatively higher Leidenfrost temperatures.

•The smaller the particle size the better the cooling – conclusion from studies in China. Albert has seen the opposite in practice with Quaker formulation?

•The focus should be on breaking the vapour phase.

•The importance of cooling properties relates to the work roll cooling impact to control work roll temperature and thermal camber.
