Solution Overview
Problem
Existing gas adsorption devices for sealed containers and thermal insulators face issues with gas-adsorptive substance consumption due to air exposure, low nitrogen adsorption capacity, and increased manufacturing complexity, particularly with moisture adsorption leading to reduced adsorption efficiency and durability.
Innovation Solution
A gas adsorption device utilizing copper ion-exchanged ZSM-5 type zeolite, combined with a primary material of lower gas barrier property, is used to suppress air exposure and enhance gas adsorption capacity, maintaining high vacuum and purity within sealed containers and thermal insulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gas-adsorptive substance is exposed to air before application, then the substance can be handled easily, but the gas-adsorptive substance is consumed by adsorbing air components and moisture
Solution Approach 1:
A protective coating layer is applied to the gas-adsorptive substance (copper ion-exchanged ZSM-5 zeolite) to act as an intermediary barrier. This coating prevents direct contact between the zeolite and air/moisture during handling and storage, while still allowing the zeolite to perform its gas adsorption function when needed. The coating serves as a mediator that protects the active substance without completely isolating it from its intended environment.
Solution Approach 2:
The protective coating is applied in advance (before the zeolite is put to use) to prevent the harmful action of air and moisture on the gas-adsorptive substance. This preliminary protective measure ensures that the zeolite does not consume its adsorption capacity during storage or handling, maintaining its effectiveness for the intended application.
2Loss of substance
If barrier containers are used to prevent air exposure, then gas adsorption material consumption is reduced, but manufacturing complexity increases
Solution Approach 1:
Instead of using complex rigid barrier containers, the invention employs a thin film protective coating applied directly to the gas-adsorptive substance. This flexible film approach provides effective barrier protection against air and moisture while being simpler to apply and integrate than rigid container structures. The thin film coating reduces manufacturing complexity compared to designing and assembling separate barrier containers.
