In a project on the subject of fiber dusts, a study is being carried out on how toxic such fiber fragments are, and which shredding technology is most suitable for preventing – or at least reducing – the release of inhalable fibers. Note de contenu : - Measuring and analyzing airborne fibers dusts - Influence of the process parameters - Estimating dust formation recommended measures - Fig. 1 : Mass-based nanoparticle concentration resulting from the shredding of the GFPP and GF-PA6 organic sheets using different shredding parameters - Fig. 2 : Mass-based particle concentration in the microscale size range, which resulted from the shredding of the organic sheets under different shredding parameters - Fig. 3 : Inhalable dust mass resulting from the shredding of the organic sheets. The dust mass has been standardized by dividing it through the mass of the input material and the quantity of the filtered air - Fig. 4 : Scanning electron micrographs of the glass fiber dusts formed during the shredding of the GF-PA6 organic sheets - Fig. 5 : AlamarBlue Test for glass fiber sheets that were shredded at different speeds but with the same screen mesh width. No cytotoxicity is visible up to the largest quantity in the study En ligne : https://en.kunststoffe.de/a/specialistarticle/fiber-dust-formation-during-the-re [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37956 [article]
