Webb23 apr. 2015 · Compared with mercury, the existence of [Zn2]2+ species is rare. We succeeded in preparing a stable [Zn2]2+ species by utilizing an MFI-type zeolite as a nano-reaction pot, which was confirmed using XAFS spectroscopy: the bands at R = 2.35 Å due to the Zn+–Zn+ scattering and at 9660.7 eV due to the 1s–σ* (th The Melt Flow Index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative … Visa mer ISO standard 1133-1 governs the procedure for measurement of the melt flow rate.
