The noodles are the key introduction of several aluminum foil mylar belts Shared by jiangyin witten. Do you know more about them? Do not understand the welcome to consult oh.
(a) air conditioning foil
Air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners. In order to improve the surface properties of plain foil, antiseptic inorganic coating and hydrophilic organic coating were applied to form hydrophilic foil before forming. At present, hydrophilic foil accounts for 50% of the total amount of air conditioning foil, and its use ratio will be further improved. In addition, there is a hate water foil, so that the fin surface with hate water function, to prevent condensation water adhesion. Due to the hydrophobic foil to improve the surface defrosting technology to be further studied, the actual production is very few.
The thickness of air conditioner foil is 0.1mm ~ 0.15mm. With the development of technology, the air conditioning foil has a trend of further thinning, and the leading product thickness in Japan is now 0.09mm. In the extremely thin state, aluminum foil pull belt must have good formability, its structure and performance must be uniform, metallurgical defects, anisotropy is small, but also requires high strength, good ductility, uniform thickness, good straightness. Specification and alloy of air conditioning foil are relatively single, suitable for mass production, but its market is seasonal, professional manufacturers of air conditioning foil, it is difficult to solve the peak season demand and low season almost no demand contradiction.
Driven by the strong market demand, in recent years, China's air conditioning foil production capacity and technical level has been improving, has formed a large, medium and small, high and low production of air conditioning foil enterprise groups, some large enterprises such as north China aluminum, bohai aluminum product quality has basically reached the international advanced level. Because domestic production capacity is superfluous, market competition is extremely intense.
(2) cigarette packaging foil
China is the world's larger cigarette production and consumption power, at present our country has 146 large cigarette factories, an annual output of 34 million large amount of cigarette box, basically using cigarette foil packaging, 30% by spraying foil, rolling aluminum foil is used 70% wheat belt, barley rolling aluminum foil tape pull consumption of 35000 tons, with improvements in people's health consciousness and imported cigarettes, smoke foil significantly slow the growth of demand, it is expected to a slight increase in recent years. China's cigarette packaging foil accounted for 70% of the total amount of double zero foil, currently there are two or three domestic enterprises can produce high-quality tobacco foil, the technical level and the international level, but the overall quality of domestic tobacco foil and the international level has a certain gap.
(3) decorative foil
Decorative foil is a kind of decorative material applied in the form of aluminium-plastic composite. Mainly used for building, furniture decoration and part of the gift box packaging. The application that decorates foil to be in our country building begins from 20 centuries 90 time, wait for central city to spread quickly to countrywide each district by Shanghai, Beijing, guangzhou, in recent years demand increases sharply, serve as the adornment material of building interior wall and interior furniture commonly, also have application in the facade of commercial organization and interior decoration.
Decorative foil has the advantages of heat insulation, moisture proof, sound insulation, fire prevention and easy to clean, and the appearance of luxury, convenient processing, construction and installation speed. At present, China's construction and home decoration industry has formed a boom in the application of decorative foil. With the rapid development of China's construction industry and decorative foil application of the continuous popularity of decorative foil demand will also have a substantial increase. In addition, the use of decorative foil packaging gifts are very popular in foreign countries, in recent years in China's rapid development.
