1100-H14 state aluminium alloy band production method.
Background technique
Aluminum alloy bottle cap material is widely used in bottle, can, medicine bottle, cosmetics as novel bottle cap joint filling material
In the outer sealing packaging of lid, punch forming is mostly processed in the higher production line of the degree of automation, performance, ruler to material
The requirements such as very little deviation, earing rate size are all very stringent, otherwise can generate rupture, folding line etc. and seriously affect and rush Gai Xiaoguo and become a useful person
Rate.
With the increasingly raising of people's living standard, the production of cosmetics capping is more and more high-grade, in the market high-grade makeup
Product bottle cap material is made from the japanning of traditional handicraft to be developed in terms of anodic oxidation, electrolytic coloring/dyeing.Because of bottle cap material
Fine and close oxidation film layer is formed in aluminium surface after anodic oxidation, its corrosion resistance, wearability and decorative performance can be significantly changed；Electricity
Appearance luster is abundant after solution coloring, and metal sense is strong, therefore current cosmetics of super quality bottle cap, high-grade IT product shell are all made of anode
Oxidation after stain or dyeing are decorative to improve its.
The requirement of cosmetics of super quality bottle cap material Surface Quality has nearly reached the quality standard of " zero-fault ", i.e. material
Surface is not allow for bright line, striped, black-white point etc defect.Aluminium and aluminium alloy anode oxide Shi Yaojing alkali cleaning and pickling, oxidation
Substrate surface and superficial layer tiny defect can be exposed or be amplified in the process, and influence the mass effect of oxidized surface, such as surface
Slight strip defect, viscous hurt point, mark etc. and will be appeared undoubtedly after anodic oxidation at secret note.Currently, doing the normal of bottle cap in the market
See that aluminium alloy and state have: 8011-H14/H16 or 3003-H16 etc., but the cosmetics of super quality bottle made by both aluminium alloys
