Aluminum foil tape, using high-quality pressure-sensitive adhesive, good adhesion, strong adhesion, anti-aging and other effects, insulation performance greatly improved. Aluminum foil tape with all aluminum foil composite material seam paste, insulation nail puncture at the sealing and repair of the broken place. It is the main raw and auxiliary materials for refrigerator and freezer production plants, and is also a necessary raw material for insulation material distribution department. It is widely used in refrigerator, air wither, automobile, petrochemical, bridge, hotel, electronics and other industries. It can be used in PDA, PDP, LCD monitor, laptop, copier and other electronic products where electromagnetic shielding is needed. It is used for wrapping outside the steam conduit to prevent the temperature from being dissipated to the outside. Non-conductive copper foil tape uses and description: Substitute enameled wire, all kinds of transformer shielding with.
The purity is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic wave to human body, and avoid the unwanted voltage and current to affect the function. In addition, it has good effect on the discharge of static electricity after grounding. The material is polyester fiber, which is not easy to crack and damage after repeated use or repeated bending. It has strong adhesion and good electrical conductivity, and can be easily wrapped and attached to the wire.
(I) Air conditioning foil
Air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners, and the early air conditioning foil used was a plain foil. In order to improve the surface performance of plain foil, a hydrophilic foil is formed by applying an inorganic coating for corrosion protection and a hydrophilic organic coating before forming. Hydrophilic foil accounts for 50% of the total air conditioning foil, and its use will increase further. There is also a hydrophobic foil that makes the surface of the fins hydrophobic to prevent condensate staining. Since the technology of water-repellent foil to improve the surface defrostability needs further research, actual production is rare. With the development of technology, air conditioning foil has a tendency to be further thinned, and the thickness of the leading product in Japan is 0.09 mm. In a very thin state, the foil must have good formability, uniform organization and properties, few metallurgical defects, and little anisotropy, while requiring high strength, good ductility, uniform thickness, and good straightness. The specifications and alloys of air conditioning foil are relatively single and suitable for mass production, but its market is highly seasonal and it is difficult for professional manufacturers of air conditioning foil to solve the contradiction between oversupply in high season and almost no demand in low season.
(II) Cigarette packaging foil
As the world’s largest producer and consumer of cigarettes, there are 146 large cigarette factories, with a total annual output of 34 million cases of cigarettes, basically using cigarette foil packaging, of which 30% use sprayed foil, 70% use calendered aluminum foil, calendered aluminum foil consumption of 35,000 tons, with the people’s health awareness and the impact of foreign imports of cigarettes, the growth of demand for cigarette foil slowed down significantly, is expected to slightly increase . Cigarette packaging foil accounts for 70% of the total double-zero foil, and there are two or three enterprises that can produce high-quality cigarette foil, with a technical level comparable to the international level.
(III) Decorative foil
Decorative foil is a decorative material applied in the form of aluminum-plastic lamination, taking advantage of the good colorability and high light and heat reflectivity of aluminum foil. It is mainly used for the decoration of buildings, furniture and part of the gift box packaging. The application of decorative foil in China’s construction industry began in the 1990s, spreading rapidly from central cities such as Shanghai, Beijing and Guangzhou to all parts of the country, with a sharp increase in demand. It is generally used as a decorative material for the interior walls of buildings and interior furniture, and is also widely used in facades and interior decoration of commercial establishments.
This is because decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fireproofing and easy cleaning, and has a luxurious appearance, easy processing and fast construction and installation. A boom in the use of decorative foil has been formed in the construction and home decoration industries. With the rapid development of the construction industry and the increasing popularity of decorative foil applications, the demand for decorative foil will increase substantially. In addition, the use of decorative foil to package gifts is also very prevalent and developing rapidly, and is expected to have a better future.
