Modern hazardous waste liquid trays adopt a multi-layer composite structure design, consisting of a gradient protection system consisting of a foundation bearing layer, a chemical barrier layer, and a surface protective layer. Its anti-seepage principle is based on a dual mechanism of "passive interception active diversion", eliminating structural joints through integral injection molding technology, and achieving rapid collection of leaked liquids with a sloping collection tank. The edge sealing strip is made of elastic deformation material, which can maintain the tightness of the contact surface even when the temperature difference changes.
Implementation path of core functions
Priority should be given to polymer based composite materials with strong intergranular corrosion resistance in material selection, and the medium's resistance spectrum should be improved through molecular structure modification. The structural innovation is reflected in the three-dimensional anti splash cofferdam design, which upgrades the traditional flat tray into a three-dimensional protective container. Intelligent products integrate multi parameter sensing arrays and use the principle of capillary phenomenon to achieve early identification of micro leaks.
Industry application characteristics
The chemical industry focuses on the protection of highly corrosive media, requiring trays to have the ability to withstand special chemicals such as hydrofluoric acid; The pharmaceutical industry focuses on maintaining cleanliness and tends to choose smooth surface treatment solutions that are easy to clean; The electronics industry requires electrostatic dissipation function and often adds conductive carbon fibers to the substrate. Emerging application scenarios such as lithium battery recycling lines need to address the risk of thermal runaway in the event of electrolyte leakage.
Technological Evolution Trends
The current research and development direction focuses on the practical application of self-healing materials, which can trigger micro repair mechanisms when cracks appear on the surface of the tray. Another breakthrough point is the development of traceable digital pallets that achieve full lifecycle management through laser coding. In the field of environmental protection, efforts are being made to explore the industrial application of bio based polymers to reduce the difficulty of handling products after retirement.
