Self-adjusting suitable-temperature type chemical product packaging bag

Abstract

The invention discloses a self-adjusting suitable-temperature type chemical product packaging bag, and belongs to the technical field of chemical products. Through the arrangement of a suitable-temperature adjusting rod, when the environment temperature is high, a memory spring can deform into a high-temperature phase shape due to heating and become long, so that a phase change heat storage body is in heat conduction connection with the outside and absorbs heat in the environment, and consequently, the influence of high environment temperature on the chemical products in a heat insulation bag cover is reduced to certain extent, meanwhile, induction refrigeration powder can provide a refrigeration effect on the basis of a magnetic refrigeration principle, so the influence of the high environment temperature on the chemical products is further remarkably reduced, and the chemical products are effectively prevented from being damaged due to the high environment temperature, and when the environment temperature is low, an elastic air bag can be shrunk when cooled, so that heat conduction connection is established between the chemical products and the phase change heat storage body, heat stored in the phase change heat storage body is guided to the chemical products, the chemical products are prevented from being influenced by low environment temperature, and the chemical products are prevented from being damaged due to the low temperature.

Description

technical field [0001] The invention relates to the technical field of chemical products, and more specifically relates to a self-adjusting temperature type chemical product packaging bag. Background technique [0002] There are various types and shapes of chemical products. Some powdery chemical products need to be packed in packaging bags after production for easy transportation, sale and use. The storage temperature requirements of some powdered chemical products are relatively strict, and the quality of chemical products will be affected if the temperature is too high or too low. The temperature difference between them is also large, and it is necessary to pay attention to the influence of temperature changes on chemical products. [0003] In the prior art packaging bags for chemical products, in order to cope with the impact of environmental temperature changes on the products during transportation, the main method is to change the packaging bag materials in a targeted...

Problems solved by technology

[0004] However, relying solely on the performance of the material itself for heat insulation has very limited effect. When the packaging bag passes through areas with high or low temperature, the chemical products in the bag are still inevitably affected by the ambient temperature, resulting in damage to the chemical products. even spoiled
