Description

Technical Field

[0001] This utility model relates to the field of composite inflatable membrane technology, and more specifically, to a polymer composite inflatable membrane structure for cleanrooms. Background Technology

[0002] Artificial light-utilizing (closed-system) plant factories are highly efficient agricultural systems that achieve year-round continuous crop production through high-precision environmental control within facilities. Utilizing intelligent technology, they automatically control conditions such as temperature, humidity, light, CO2 concentration, and nutrient solution for plant growth, enabling a factory-like production model where plant growth is not constrained by natural conditions. Air-supported membrane structures, when applied to artificial light-utilizing (closed-system) plant factories, can better provide cleanrooms and easily achieve an ideal environment for internal cultivation. The air-supported membrane structure is fully enclosed, effectively isolating external noise, dust, and pollutants, providing a highly isolated, dust-free environment and ensuring the purity of the cleanroom environment. Equipped with an advanced fresh air system, it monitors air quality and gas content in real time. External air enters the room through a fresh air filtration system, completely preventing insects, dust, and harmful gases from entering, meeting cleanliness standards.

[0003] Most existing air-supported membrane structures used in cleanrooms are single-layer structures. During use, cleanrooms require artificial lighting and temperature and humidity control, and are greatly affected by the external environment. LED supplementary lighting has low energy utilization, and there are high requirements for user and environmental control. At the same time, traditional plant factories have poor airtightness, and insects and dust can easily enter, affecting product quality.

[0004] In summary, in order to address the issues of air-supported membrane structures being susceptible to external environmental influences and internal contamination during factory production, it is necessary to improve the insulation capacity of the air-supported membrane structure, enhance its thermal insulation effect, ensure the active removal of pests and dust, and improve product quality.
