SpletIt was found that the swelling and shrinking behaviour of the ionogels is strongly dependent on the nature of the ionic liquid. In particular, the [P6,6,6,14][NTf2] ionogel exhibits the greatest degree of swelling, reaching up to 180% of its initial size, and the fastest shrinkage rate (ksh = 29 ± 4 × 10−2 s−1). shenzhen hifrozen intl logisticsSpletChemical Reactor is known as the heart of any chemical plant since the new chemicals are produced only in this vessel and the economics of the entire plant depends on the design … shenzhen hifrozen intl logistics dvpt co. ltdSplet27. okt. 2016 · Evaluation of shrinking core model in leaching process of Pomalaa nickel laterite using citric acid as leachant at atmospheric conditions - IOPscience This site … shenzhen hidin technology co. ltdSpletShrinking-Core Model As we know, while leaching a solid with a liquid the solid goes to the liquid phase while the earlier one remains.
