The inorganic desiccant calcium chloride is a high-efficiency adsorption material, and the main components of the inorganic desiccant calcium chloride and the colloidal starch are calcium chloride and colloidal starch. The water molecules and the calcium chloride are chemically reacted in a chemical mode, the calcium chloride absorbs moisture from the surrounding environment and is converted into gel, the calcium chloride can absorb 300% of the weight of the calcium chloride, the moisture absorption rate is 8-15 times that of a common drying agent, a good adsorption effect is achieved, and the possibility of leakage is reduced.
The inorganic desiccant silica gel is a high-activity adsorption material, mainly contains silicon dioxide, and has the following characteristics: high adsorption performance, good thermal stability, stable chemical property, higher mechanical strength and the like. The silica gel has a superfine pore network structure inside, and the capillary pores can absorb water and retain the water by the attraction of the surface adsorption in the capillary pores for drying and moisture prevention.
The preparation process of the acid activated modified montmorillonite clay comprises the following steps: weighing 21-40 parts of montmorillonite clay and 12-20 parts of mixed solution of sulfuric acid and hydrochloric acid, uniformly mixing in a dispersion kettle, placing the dispersion kettle in an oil bath at 65-68 ℃ to remove molecular water and organic matters on the montmorillonite clay, stirring and dispersing for 1-1.5 h in the dispersion kettle at the dispersion speed of 1200-1250 rpm, and then adding 15-20 parts of oxalic acid into the montmorillonite clay in the dispersion kettle after suction filtration and drying; and raising the reaction temperature to 250-260 ℃, preserving the temperature for 2-3 hours to remove the structural water of the montmorillonite clay, carrying out reduced pressure distillation for 4-6 hours, carrying out suction filtration, and drying to obtain the acid activated modified montmorillonite clay. The mixed solution of sulfuric acid and hydrochloric acid is a mixed solution prepared from a 65-68% sulfuric acid solution and a 18-20% hydrochloric acid solution according to a weight ratio of 3-4: 1-2.

The inorganic desiccant montmorillonite clay has gray small sphere shape, and is suitable for absorbing moisture in an environment below 50 ℃. When the temperature is higher than 50 ℃, the water discharging degree of the clay is larger than the water absorbing degree. But clay has the advantage of being inexpensive. The mechanism of acidifying modified bentonite is to utilize different types and concentrations of acid to treat raw bentonite, and to eliminate impurity distributed in the montmorillonite clay passage as the main mineral component of bentonite, such as organic matter mixed in the bentonite, so as to dredge the passage and facilitate the diffusion of adsorbed matter molecules.
