Abstract

The utility model relates to a measure laboratory device of material iodine adsorption performance mainly comprises inside and outside two parts, and the outside is a glass bottle, and inside is a support that holds porous material, comprises lead screw, screw cap, packing ring, glass recess and glass ware. The upper part of the screw rod penetrates through the center of the bottle cap and is fixed and adjusted through the upper screw cap and the lower screw cap. During the experiment, the sample material is placed in a glass vessel, the glass vessel is placed in a glass groove, then a proper amount of solid iodine is placed at the bottom of a glass bottle, and the glass vessel is taken out after the experiment is finished.

Description

Laboratory device for measuring iodine adsorption performance of material

Technical Field

The utility model belongs to measure adsorption equipment, in particular to a laboratory device for measuring porous material iodine adsorption capacity.

Background

At present, most of devices for measuring the iodine adsorption performance of porous materials in laboratories are large bottles and small bottles, namely, a sample to be measured is placed in an open small bottle, then the small glass bottle is placed in the large glass bottle containing a proper amount of iodine, the bottle mouth is sealed, and finally the small glass bottle is placed in a heating device. In the experimental heating process, the iodine solid is sublimated into gas to fill the large bottle, but when the sample adsorbs iodine vapor, partial iodine substances are attached to the inner wall and the outer wall of the small bottle for containing the sample, especially to the bottom of the small bottle. And when the small bottle is taken out and cooled after the experiment is finished, the iodine vapor in the small bottle is desublimated into solid and falls into the bottom of the small bottle, which affects the accuracy of the measurement result.

Disclosure of Invention

The utility model aims at providing a reduce its measuring error's laboratory auxiliary device in test material iodine adsorption experiment. Therefore, in view of the problems in the iodine adsorption experiment, the device is improved, the large bottle for manufacturing the closed system is not changed, the small bottle inside is changed into a bracket, the direct contact of an appliance with iodine substances is avoided, the measurement error is reduced, and the sample is convenient to take in. The experimental device is simple in composition, convenient to operate and high in practicability, and can be used for testing the iodine adsorption performance of a small amount of materials.

The technical scheme is as follows: the utility model provides a measure laboratory device of material iodine adsorption performance, includes lead screw, screw cap, packing ring, frame, glass recess, glass ware and glass bottle, its characterized in that: the screw rod penetrates through the center of the bottle cap, the support is adjusted and fixed through the upper screw cap and the lower screw cap, and the bottom of the support is preferably away from the bottom of the bottle by a certain distance. The lower end of the screw rod is connected with a frame with a glass groove, and the glass groove is fixed on the frame and keeps stable. The glass vessel used for containing the samples is stored in the groove, so that the area of the glass vessel exposed outside is reduced, and the samples can be conveniently contained and taken out. One side of the glass vessel is provided with a handle, so that the glass vessel can be conveniently taken out of the groove. And finally, placing the bracket fixed on the bottle cap into the bottle, and screwing the bottle cap tightly.

The gasket is arranged between the screw caps, so that the bottle cap is prevented from being excessively worn by force, and a better sealing effect is achieved.

The iodine vapor measuring device has the advantages that the direct contact between the container for containing the sample and the solid iodine is avoided, the area of the container for containing the sample exposed in the iodine vapor environment is greatly reduced, and the error in the aspect of measurement is greatly reduced. In addition, the utility model discloses can use the glass bottle instrument of most specifications as the closed system, constitute simply, convenient operation, the practicality is strong.
