The invention relates to the technical field of high polymer crystallization speed measurement, and in particular relates to a crystallization melting furnace and a high polymer optical depolarizer. The crystallization melting furnace comprises a shell; a through hole is formed in the shell; the shell is internally provided with a sliding device; the sliding device is internally provided with a ceramic heating device and a liquid nitrogen cooling pipeline; the surface of the sliding device is provided with a sample groove; a glass slide loaded with a high polymer sample is detachably and fixedly arranged in the sample groove; and the sample groove of the sliding device is provided with a light hole; the adjusting device is used for enabling the sliding device to move in the X direction andthe Y direction. The high polymer optical depolarizer comprises the crystallization melting furnace. By controlling the heating time and temperature of the ceramic heating device and controlling a control valve to be opened and closed, the temperature of the crystallization melting furnace can be controlled within an extremely short time, and therefore automatic control over the melting process and the crystallization process is achieved.
Description
technical field [0001] The invention relates to the technical field of polymer crystallization speed measurement, in particular to a crystal melting furnace and a polymer optical depolarizer. Background technique [0002] The melting furnace and the crystallization furnace of the existing optical depolarizer are two separate furnace bodies, and the melting furnace and the crystallization furnace are controlled to have different working temperatures by a control element. For example, the applicant's application number is 201711098593X patent. When this polymer optical depolarizer is working, it needs to melt the polymer sample placed on the glass slide in a remelting furnace, and then The slides were taken out and placed on the crystallization furnace for optical detection. Since the polymer optical depolarizer is operated in two separate steps, melting and crystallization, it is very inconvenient and the user experience is not good.
