| Abstract;Flotation is the most important process for increasing brightness, removing hydrophobic contaminants in Deinking system. Particularly, smaller ink particles have a big influence on brightness than bigger ones. Since 1985, many new Technologies were applied for NDIP (News to News) to detach ink particles from fibers and therefore improve appearance of the paper. As an example there is the High consistency pulping, Serial Kneading/Dispersing, high consistency soaking and new type of Soap with strong penetration. The result was that ink particles were made smaller and smaller during the detachment of the deinking process. Because of that deinking system requires the removal of smaller particles by innovative flotators. In 1990, the MT-Flotator has been developed by Ishikawajima Heavy Industries (IHI), Ishikawajima Industrial Machinery (IIM) and was awarded the Sasaki's prize by Japan Tappi on 2005. Since 2001, Voith-IHI Paper Technology Co., Ltd. is the developing centre of MT-Flotator technology. This presentation picks up some of the advanced technologies of the MT-Flotator. Additional to that the new generation of MT II-Flotator is also introduced. (author abst.) |
