Embodiment Construction

[0018] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0019] Such as Figure 1 to Figure 6 The moisture absorption rate tester shown includes an air pump 1, an air humidifier 2 and a drying device 3.

[0020] The air humidification device 2 described in the present application includes a housing 201, a first reagent bottle 202 and a second reagent bottle 203. The first reagent bottle 202 and the second reagent bottle 203 are arranged on the housing 201 and have an upward opening. The first reagent bottle 202 contains water, and the second reagent bottle 203 contains saturated ammonium chloride solution; the mouth of the first reagent bottle 202 is provided with a first stopper 220, and the first bottle The plug 220 is provided with two first through holes (not shown in the figure) penetrating the top and bottom of the plug 220. A first inlet pipe 204 and a first outlet pipe 205 are respectively provided in the ...

Abstract

The invention discloses a moisture absorption rate tester which comprises an air pump, an air humidification device and a drying device. The air humidification device comprises a shell, a first reagent bottle and a second reagent bottle; water is held in the first reagent bottle; an ammonium chloride saturated solution is held in the second reagent bottle; a first air inlet pipe and a first air outlet pipe are arranged in the first reagent bottle; the top end of the first air inlet pipe stretches out of the first reagent bottle and is connected with the air pump through a first hose pipe; a second air inlet pipe and a second air outlet pipe are arranged in the second reagent bottle; the drying device comprises a dryer and a glass dish; a third air inlet pipe and a third air outlet pipe with two ends being located on the inner part and the outer part of the dryer are arranged in the dryer. The moisture absorption rate tester provided by the invention has the beneficial effects that airis firstly humidified, then the ammonium chloride solution is fed into the humidified air, the humidity of air passing through the ammonium chloride saturated solution is maintained at a basic stablestate around 78 percent, and under the same humidity, the test of the moisture absorption rate of a drying agent is more accurate.

Description

Technical field [0001] The invention relates to a moisture absorption rate tester. Background technique [0002] The moisture absorption rate of the desiccant is one of the parameters to measure the quality of the desiccant, especially the powdered desiccant. For the powdered desiccant, the moisture absorption rate test is to place the desiccant in the desiccator and add it to the desiccant. Pass in air, measure the mass difference before and after the desiccant absorbs moisture in the air within a specified time, and use the percentage of the mass difference to the mass before the desiccant absorbs moisture in the air as the moisture absorption rate of the desiccant. [0003] The current test of the moisture absorption rate of the desiccant has the disadvantage that it is difficult to maintain the uniform humidity of the air passing through the desiccant within the specified time. It may be that the humidity of the air in a certain period of time is high, and the humidity of the a...
