It is also useful to fulfil the requirements of new regulations such as the Chinese energy reduction plan for light industry of 20% by 2015. W2O environment has implemented new technologies at Simona Tanning, which have been selected according to Best Available Technology (BAT) by reducing energy consumption and increasing the treatment efficiency and effluent quality. Simona Tanning is a pioneer implementing BAT for highly efficient tannery effluent treatment, generating lowest possible carbon emissions, and can be considered to operate the best performing tannery effluent treatment plant in China.

Morphological characterization of PE blown films by atomic force microscopy / Musa R. Kamal in INTERNATIONAL POLYMER PROCESSING, Vol. XVI, N° 4 (12/2001)  

[article]  inINTERNATIONAL POLYMER PROCESSING > Vol. XVI, N° 4 (12/2001) . - p. 376-387 Titre : Morphological characterization of PE blown films by atomic force microscopy Type de document : texte imprimé Auteurs : Musa R. Kamal, Auteur ; Z. Tang, Auteur ; T. Huang, Auteur Année de publication : 2001 Article en page(s) : p. 376-387 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : The properties of blown polyethylene (PE) films depend on various factors, including crystallinity, morphology, and orientation, in addition to chemical composition. It has been shown that the optical properties are strongly influenced by surface morphology. In this work, non-contact atomic force microscopy (AFM) and polarized light microscopy (PLM) were used to visualize surface and bulk morphology. Various techniques, such as surface and line roughness, surface and line fractal dimension, pair-correlation function and nearest neighbor distance distribution function, are employed to quantify the description of morphology and to compare the morphological characteristics of a number of polyethylene (PE) films of commercial interest. A comprehensive quantitative analysis of surface topography has been performed. The co-monomer of the PE resins was found to play a significant role in the formation and the orientation of spherulite-like domains. The film cross-section microstructure has been evaluated quantitatively by using both AFM and PLM. However, quantitative analysis of bulk morphology cannot be obtained due to knife effects.
