HHF Foil Micron Thickness Specification
The specifications of aluminum foil are closely related to its use. In many cases, specifications can also determine the price of aluminum foil, so it is very important to provide the correct specifications when purchasing products.
Different specifications divide aluminum foil into different categories, and their uses are also different. But no matter what kind of aluminum foil, the same problem will be encountered many times in the production process.
Bright spots, bright spots, and bright spots may appear first. The double-sided bright spots, bright marks, and bright spots caused by improper use of double oil are mainly due to insufficient double oil film strength, or uneven roller surface deformation due to uneven roller surface, and the appearance is pitted or foreign. Material invasion. .Selecting a reasonable double oil, keeping the incoming material clean and the roller surface uniform are effective measures to solve such defects.
Difference in thickness. Difficulty in controlling the thickness difference is a characteristic of rolling. The thickness difference of 3% may not be difficult in the production of plates, but it is very difficult in the production of aluminum foil. The reason is that the thickness is thin, and other trace conditions such as temperature, oil film, and oil and gas concentration will also affect it.
A roll of aluminum foil can be rolled up to hundreds of thousands of meters, and the rolling time is up to 10 hours. Over time, it is easy to form thickness differences, and the only way to adjust the thickness is the tension speed. These factors make it difficult to control the rolling thickness of aluminum foil. Therefore, it is quite difficult to truly control the thickness difference within 3%, which requires many conditions to guarantee.
Then there may be water spots. Water spots refer to the white spots formed by water droplets on the surface of the foil before rolling. When it is slight, it will affect the surface condition of the foil surface, and when it is severe, it will cause the strip to break. Water spots are formed by water droplets in the oil or falling on the surface of the foil in the rolling mill. Controlling the moisture and water source in the oil is the only way to avoid water spots.
