Water Solutions

In porous materials filled with water or water solutions of inorganic salts, water freezes at lower temperatures than under normal conditions; the reason is the decrease of water vapor tension above the convex meniscus of liquid in pores. The freezing point depression is not very significant in pores with radii from 0.05 μm to 10 μm (about 0.01-2.5 K). Only in smaller pores, especially when filled with inorganic salt solutions, this depression is important.

Abstract Salt hydrates (MgSO4 and ZnSO4) impregnated in zeolites, offer a variety of improvements, mostly providing a large surface area for salt hydrates and water molecules. A composite of 5 and 10% of salt contents were prepared as heat storage materials. The study’s finding showed that dehydration enthalpy of MgSO4 (1817 J g−1) and ZnSO4 (1586 J g−1) were 10 and 15% improved than pure salt hydrates by making composites. During the hydration process of composites, the water sorption is 30–37% improved and further the increasing of salt contents in composites enhances more 10% increase in the water resorption. The cyclicability of MgSO4/zeolite and ZnSO4/zeolite were 45 and 51% improved than their corresponding pure salt hydrates. The effect of humidity on the water sorption result reveals that composites of MgSO4/zeolite and ZnSO4/zeolite at 75% relative humidity (RH), the mass of water are 51 and 40% increase than 55% RH.

Scale Inhibition

Scale inhibitor is a medicament which has the properties of dispersing insoluble inorganic salt in water, and preventing or obstructing sediment and scaling of insoluble inorganic salt on metal surface. Research on the mechanism of scale inhibition can promote using and developing scale inhibitors. In this paper, the traditional macroscopic mechanism of scale inhibition was firstly analyzed, and it was also emphasized to introduce the research progress of quantization simulation technique on the mechanism of scale inhibition, and it was also suggested to combine the microstructure of scale crystal with quantization simulation technique to have a further study on the mechanism of scale inhibition.
