Abstract

PURPOSE:To obtain a drying agent which is high in absorption capacity, easy in handling and reutilizable by mixing powdery anhydrous calcium chloride with powdery anhydrous magnesium sulfate in the specified proportion as the drying agent. CONSTITUTION:As a drying agent, powdery anhydrous calcium chloride is mixed with powdery anhydrous magnesium in the proportion of 5-30wt%. By this method, the hydroscopic capacity of both components is increased and the drying agent is not liquefied and solidified by deliquescing even if it absorbs moisture, therefore its handling is easy and furthermore it is immediately made to the reutilizable state when it is heated and dehydrated.

The purpose is to provide a desiccant that has a drying effect and is easy to use. In the drying agent characterized by the fact that it is mixed, if the anhydrous lucium chloride content is lower than 51% by weight, the drying ability is weakened and no particular difference from the conventional one was observed.

It deliquesces into a liquid state and does not become sticky or solidify. Therefore, it is clean and convenient to handle.
If you heat and dehydrate it with an IE microwave oven, electric iron, etc., it will be ready for use immediately.

On the 33rd day, the temperature was increased from room temperature to approximately 30°C. The increase in blood filtration in the bag due to the absorption of moisture by the chest desiccant agent was determined over time. A comparative test was conducted under the same conditions.

試験結果 試験結果は図面に示す通りの吸湿曲線となりた。Test results The test results showed a moisture absorption curve as shown in the drawing.

Anhydrous calcium chloride alone deliquesced at a Wi humidity of 45%. On the other hand, the desiccant of this example had a moisture absorption rate comparable to that of the desiccant containing anhydrous calcium chloride alone, was not deliquescent, and reached a moisture absorption rate of nearly 100%. This is about 1.5 times the drying agent of anhydrous magnesium sulfate alone.
