Weifang JS cacl2, an alkaline-earth crystal salt, is calcium chloride. It has many commercial uses. It has an aqueous solubility of 30–45 weight percent, is highly hygroscopic, and liberates large amounts of heat during water absorption and dissolution.
CaCl2 is a useful ice-melting material due to its hygroscopic and deliquescent properties. It lowers the freezing point to allow more ice and snow to melt on contact. CaCl2 also attracts moisture from the atmosphere, making it a dust suppressant for gravel roads, construction, and maintenance.
Weifang JS Green CaCl2 (cacl2 2h2o) is one of the most widely applied chemical sorbents for air desiccation, sorption refrigeration, and gas purification. This sorbent has a high water adsorption capability, excellent chemical stability, and excellent cycle performance. It is also low in cost and does not cause any environmental pollution. However, the water content in the adsorbent limits its sorption ability. Methods have been developed to increase the sorption rate.
Several techniques have been used to increase the sorption rate of CaCl2-based composites. They can include the adjustment of the critical relative humidity (g), an increase in the specific surface area, and the addition of NaCl powder. In this study, a CaCl2/CNTs composite with a large specific surface area was prepared by coating CaCl2 powder on the surface of carbon nanotubes. It reached sorption equilibrium in 4 hours and had a 75% higher sorption rate than pure CaCl2 powder. In addition, adding NaCl powder to a saturated CaCl2 solution could significantly decrease the g of the solution and improve its sorption rate.
The pore size of the composites as well as the hydration cycle of cacl2 cl2 were determined by XRD and EDAX/SEM measurements. The pore size was measured as the average diameter of pores in a square cross section, while the hydration rate was measured as the ratio of Weifang JS hydrated CaCl2 particles to total CaCl2 atoms. The hydration rate of the composites was measured at different temperatures for desorption and adsorption and at a fixed water pressure of 12.3mbar. The composites' adsorption rates are affected by the desorption and adsorption temperatures.
Furthermore, the adsorption and desorption rates of PHTS were measured with a polarization method and dynamic tests. A PHTS with 4-CaCl2 was compared to a non-functionalized one with an SBA-15 matrix. Both PHTS had uniform mesopores and larger pore volumes, which resulted in higher sorption uptake. The adsorption/desorption rate was determined for five successive hydration cycles at 30% RH.
In addition, the water adsorption rate of the PHTS with 10-CaCl2 and 20-CaCl2 was also determined by a polarization method and dynamic tests. The adsorption/desorption cycle of the PHTS with Weifang JS 10 cacl2 in water was significantly faster than that of the non-functionalized PHTS with SBA-15, and the energy storage capacity was significantly higher for the non-functionalized PHTS.

A novel PHTS-CaCl2 composite with different adsorption temperatures and a dew point temperature of 10 u00b0C was also prepared. The adsorption and dessorption temperatures were set at 40, 120, and 12 mbar, respectively. The difference in adsorbed water amounts at 40 and 120 deg C at 12.5 m bar was the water lift of the composite. This value was compared to the integral heat of the adsorption. It showed that the composite had a high water-adsorption capacity at low temperatures, which is encouraging its use in low-temperature thermal energy storage applications.
The water adsorption capacity of the composite with 4-CaCl2 was significantly higher than that of the non-functionalized phosphate-ion exchanger (PIE) PHTS, indicating that the presence of calcium chloride in the PHTS increased its hydrophilic properties. The adsorption and desorption times of the PHTS with 4-CaCl2 were significantly shorter than those of the non-functionalized PIE, which suggests that the PHTS with 4-CaCl2 has a more stable microstructure than the PIE. Another type of product on the market is the cacl2 salt.
