а) Фольга для кондиціонування

{0}}Фольга для кондиціонування повітря – це спеціальний матеріал для виготовлення ребер теплообмінника для кондиціонерів. Фольга{1}}кондиціонування повітря, яку використовували на початку, була звичайною фольгою. Для покращення поверхневих властивостей звичайної фольги перед формуванням для утворення гідрофільної фольги наносять антикорозійне неорганічне покриття та гідрофільне органічне покриття. Гідрофільна плівка становить 50% від загальної кількості фольги-кондиціонування повітря, і її співвідношення буде збільшено. Крім того, є водовідштовхувальна-фольга, завдяки якій поверхня ребер має водовідштовхувальну-функцію, щоб запобігти прилипання конденсованої води. Оскільки технологія гідрофобної фольги для покращення поверхневого розморожування потребує подальшого вивчення, фактичного виробництва мало.

The thickness of the air conditioner foil is {{0}}.1mm to 0.15mm. With the development of technology, there is a trend of further thinning of air-conditioning foil, and the thickness of Japan's leading product is 0.09mm. In an extremely thin state, alumaluminium foil jumbo rollinum foil must have good formability, its structure and properties must be uniform, less metallurgical defects, small anisotropy, high strength, good ductility, uniform thickness, and good flatness. The specifications and alloys of air-conditioning foil are relatively simple, which is suitable for mass production, but its market is seasonal, and it is difficult for professional manufacturers of air-conditioning foil to solve the contradiction between the shortage of supply in peak season and almost no demand in off-season.

Due to the strong market demand, the production capacity and technical level of my country's air-conditioning foils have been continuously improved in recent years, and now a group of large, medium and low-level enterprises producing air-conditioning foils has been formed. Some large enterprises such as North China Aluminum and Bohai Aluminum have basic product quality Has reached the international advanced level. Due to the excess domestic production capacity, the market competition is extremely fierce.

my country is the world's largest producer and consumer of cigarettes. At present, there are 146 large cigarette factories in my country, with an annual output of 34 million large boxes of cigarettes, which are basically packed in cigarette foil, of which 30 percent are sprayed foil and 70 percent are rolled. The consumption of aluminium foil jumbo roll and rolled aluminium foil jumbo roll is 35,000 tons. With the enhancement of people's health awareness and the impact of imported cigarettes, the growth of demand for cigarette foil has slowed down significantly, and it is expected to increase slightly in recent years. my country's cigarette packaging foil accounts for 70 percent of the total double-zero foil. At present, there are two or three domestic companies that can produce high-quality cigarette foil, and the technical level is comparable to the international level.
