Due to its excellent properties, aluminum foil has been widely used in many fields such as transportation, packaging containers, architectural decoration, machinery and electrical appliances. In recent years, facing the increasingly fierce competition in the industry, aluminum foil companies have actively developed new products and further expanded the application fields of aluminum foil through innovative designs and improved product performance. For example, the aluminum foil composite tiles produced by Luoyang Qianqing Tile Industry Co., Ltd. on display in the aluminum packaging public welfare exhibition area are made of aluminum foil composite on both sides. They have the characteristics of reflection, heat insulation, fire prevention, corrosion resistance, etc., and can effectively reduce solar radiation. According to the "National Chemical Building Materials Testing Center" test, the reflective ratio reaches 84.5% and has excellent heat insulation function. Every hot summer, the indoor temperature of color steel tiles and asbestos tiles is usually above 40 degrees due to heat absorption, while the indoor temperature of aluminum foil composite tiles can be controlled below 30 degrees, which has the effect of saving electricity and energy. It is an ideal choice for the breeding factory industry. The ideal tile material for factory buildings is expected to replace color steel tiles and asbestos tiles, and has been widely used in the field of building energy conservation.
Although China has overcapacity in aluminum foil, it still relies on imports for some high-end products. This has also become the focus of aluminum foil companies in recent years and has achieved some results. At this exhibition, some aluminum foil companies also brought new products that are expected to replace imports through technological innovation. For example, the rare earth-modified ultra-thin aluminum foil for cathode current collectors produced by Jiangsu Changlu Aluminum Group Co., Ltd. has a tensile strength greater than 250MPa, a conductivity greater than 57.5%ICAS, and a limit thickness of only 10 μm. Its overall performance exceeds that of similar products. Imported products are expected to achieve import substitution. In addition, LX02-low-voltage anode foil for solid-state capacitors independently developed and produced by Ruyuan County Lidong Electronic Technology Co., Ltd. is a key material for solid-state aluminum electrolytic capacitors. Previously, this field was almost monopolized by Japanese JCC Company and KDK Company; The performance indicators of this product meet the needs of high-end products, break the foreign monopoly, and are conducive to the rapid development of my country's capacitor industry.
