Aluminum foil in daily life has a very wide range and mature applications, mainly in food packaging, pharmaceutical aluminum foil, battery soft package and other fields have a better performance, the thickness of aluminum foil is generally less than 0.2mm, according to the thickness of the subdivided, can be padded for thick foil, single-zero foil, double-zero foil three kinds. Thick foil thickness of 0.1 ~ 0.2mm, single zero foil thickness: 0.01mm and less than 0.1mm foil, double zero foil thickness is measured in mm as a unit of measurement after the decimal point there are two zeros of the foil. Aluminum foil is used so much, and the breakdown is so clear, its processing technology is also more mature, but the processing process should still pay attention.
Precautions in the production of aluminum foil
It is necessary to pay attention to the following four basic matters:
1, first of all, we should control the quality from the source, and strictly inspect the billet;.
2, and then in the rolling process, through the roll cleaning and roughness control, rolling oil selection, reduce the viscosity of the rolling oil and control of the machine's operating speed and other aspects of the control of surface quality;.
3, in the slitting process, to ensure that the slitting of aluminum coil edge part of the flush, can not appear ruffled edges and other quality problems.
4, finally in the annealing process, according to the performance requirements of the aluminum foil to control the annealing time and annealing temperature, to ensure that clean oil removal.
With the development of aluminum foil production process, pharmaceutical aluminum foil with its excellent moisture resistance, barrier properties, drug resistance, chemical stability, hygiene, the proportion of applications continue to rise, the appearance and quality requirements are also higher and higher, the market outlook is very broad. Many aluminum foil manufacturers strictly control the quality of aluminum foil production, according to the study of different uses of aluminum foil and make corresponding processing requirements, to ensure that to bring customers a high quality experience and meet customer needs.
