The Latest Development of Aluminum Foil Production Technology
2017/2/15 17:20:40
Aluminum foil production technology in recent years has undergone great changes in the past that is very mysterious 5.5 microns, 5 microns, 4.5 micron products, with the smelting technology to improve, almost become a common product. The surface of the high degree of concern, making the printing means of detection, color aluminum foil as a routine detection means. The number of pinholes measured in square meters becomes more accurate in square centimeters, and pinhole on-line testing is increasingly applied to finishing equipment, and the widespread use of the pen is replacing the original brushing test. The use of micro-alloying means to accurately adjust the performance of aluminum foil has become a trend. And from the tobacco packaging, food packaging more stringent control of harmful elements, aluminum foil production technology is more stringent requirements. Tetra Pak packaging is also becoming a product in addition to the threshold of certification without any technical difficulty of the product, the general application of the rewinder to make aluminum foil product quality verification work as a necessary means.
Aluminum foil, especially double-foil is becoming a common commodity, a more stringent requirements, more and more mature technology standardization products.
Aluminum foil production equipment has been digested and absorbed by the domestic, which benefited from more than 30 years of aluminum foil production core technology understanding and accumulation.
From all angles, China has become the world's foil power. Not only has the world's largest production capacity, but also brings together the world's most advanced equipment, has accumulated the most advanced technology, with the world's largest manufacturing enterprises.
According to the use of aluminum foil can be divided into: soft foil, cardboard foil, tobacco foil, wine standard foil, cable foil, medicine foil, home foil and so on. These are basically traditional aluminum foil for packaging. With the continuous development of science and technology, aluminum foil in the use of electronic products also cut a striking figure, but also in the amount of electronic products also increased several times the year. Such as: aluminum foil for batteries, electronic capacitor foil, electronic label foil and so on.
In general, the electronic capacitor foil foil thickness requirements of the thinnest, commonly used specifications in the 0.005 ~ 0.006mm or so, requiring an annealing state.
Battery aluminum foil commonly used in the thickness of 0.01 ~ 0.03mm or so, requiring the general H18 hard state. The aluminum foil on the product requirements are higher, especially for the plate type requirements.
Electronic label foil is made of electronic sealing circuit of aluminum foil, the thickness is generally above 0.015mm and annealed, such products on the aluminum foil pinhole, pitting, pits require a higher.
With the continuous enrichment and development of electronic products, I believe that aluminum foil in the electronic product market will be more and more widely, will become the aluminum foil industry a new important development trends and opportunities.
