Description

TECHNICAL FIELD

[0001] The utility model relates to raw material container technology field especially relates to a kind of high-temperature heat treatment, storage and transportation, filling integrated box for easy hygroscopic powder. BACKGROUND

[0002] Dianhydride monomer is an easy hygroscopic powder, and it is a small molecular compound containing two anhydride groups at both ends, which can be used in the field of high polymer material synthesis. By polycondensation with diamine monomer in organic solvent, polyamide acid polymer solution is formed, and then through special equipment, polyimide fiber or film products with high heat resistance and high strength are processed. The quality of the final product is closely related to the dianhydride monomer as raw material. Dianhydride monomer is easy to absorb water, and the anhydride group combines with water to form a carboxylic acid group. The carboxylated anhydride monomer does not have the ability to react with amine to form a polymer. For this anhydride monomer contaminated by water vapor, heat treatment at a high temperature of about 250 degrees for several hours is generally used to restore the carboxylic acid structure generated by combined water to anhydride group. In this way, it can be reused for the synthesis of high-performance resins such as polyimide.

[0003] Currently, the heat treatment process of dianhydride monomer usually involves placing the raw material in an open wide-mouth tray, then heat treating it in a high-temperature oven, and then transferring the raw material in the tray to a sealed raw material bag or sealed container after the oven cools to room temperature. Then, when using, a specific weight is weighed by a weighing scale through a weighing bag, and then the raw material in the bag is added to the reaction kettle. During the entire heat treatment and use process, the raw material is in contact with the open environment for more than three times. In this process, there is a high probability that the raw material will be contaminated by water vapor in the atmosphere again, which will affect the use effect of synthesis. At the same time, the frequent container transfer of the raw material causes a certain loss of raw material each time during the transfer process, resulting in loss and affecting the accurate measurement of the reaction. Not only does it need frequent numerical correction, but the raw material remaining in the container during each transfer process is also easy to contaminate the subsequent raw material. Therefore, if there is a way to reduce the frequent container change of the raw material during the storage, filling and high-temperature heat treatment processes, and to reduce the opportunity of contact with air except for the unloading and opening of the bag and the final use link, it will greatly help the accuracy of the synthesis experiment, the time of frequent processing of the raw material and the reduction of material loss. It has important practical significance for the loss control and cost control in the production process of polyimide products. UTILITY MODEL CONTENTS
