Double-zero Aluminum foil Jumbo roll for Lamination or Flexibale Packaging
Production General Information
High-quality double-zero aluminum foil has become the mainstream of today's market demand, and it is also the goal and direction pursued by all aluminum foil manufacturers to seize the market and improve efficiency.
In order to obtain an aluminum foil product with a small number of pinholes and a high yield, the quality of the aluminum foil blank must be strictly controlled.
Aluminum melt combined purification treatment is the primary task of aluminum foil blank production, and it is the premise and guarantee for obtaining high quality double zero aluminum foil.
At present, the production of double-zero aluminum foil mainly adopts the casting and rolling method, and the micro-structure control of the billet in the process of melt purification, alloy composition control and processing is the three key technologies of continuous casting and rolling.
The number of pinholes is one of the main criteria for measuring the quality of double-zero aluminum foil.
The tendency of aluminum foil pinholes is mainly determined by the melt hydrogen content.
For the production of ultra-thin aluminum foil, the lower the hydrogen content of the melt, the better the hydrogen content is generally less than 0.14 ml / 100 g of Al.
