Abstract

The invention discloses a preparation device of self-repairing cellulose hydrogel and an intelligent control system of the preparation device. The intelligent control system comprises an MCU (Microprogrammed Control Unit), a stirring module, an induction module, an alarm module, a suction filtration module, a drying module, a weighing module, a water level detection module, a heating module and a valve control module, wherein the water level detection module is used for inducing the water level H in a solvent device, and the induction module is used for inducing whether materials pass through a feed opening of a drying device; the MCU is used for controlling the stirring module, the alarm module, the suction filtration module, the drying module, the weighing module, the heating module and the valve control module to perform related operations according to an induction value, a detection value and a received digital signal. According to the preparation device and the intelligent control system, all parameters such as the temperature, the water level and the time can be accurately controlled in a preparation process, and the degree of automation is high; manual control and automatic control are combined, the operation is facilitated, and the time is saved; the preparation cost is low, the effects of stability and reliability are achieved, and the quality of prepared finished products is high.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a self-repairing cellulose hydrogel preparation device and an intelligent control system thereof. Background technique [0002] During the manufacture and use of polymer materials, when subjected to external mechanical damage, due to internal micro-cracks and local damage, the performance will decrease and the service life will be affected. Because the cracks of polymer materials often appear deep inside, it is more difficult to detect than ordinary metal materials. Self-healing polymer materials can find cracks by themselves and heal themselves through a certain mechanism. It is a polymer smart material that has a wide range of application requirements. Therefore, using the ease of processing of polymer materials to study bionic self-healing has become a hot topic in the field of polymer science since it was proposed by Dry et al. in 1996. [0003] As a high water absorption a...
