Aluminum Boiling After Al Had Mysteriously Disappeared, What's Going On Here?
Nov 25, 2016

Aluminum boiling layer after the mysterious disappearance of reasons:

PET film manufacturers

Containing additives primarily composed of silicon dioxide, does not react with the aluminum

Aluminum boiling layer after the mysterious disappearance of reasons:

Second, the ink manufacturer

PH of inks for neutral and there are no other components that may react with aluminum [DIC said, some color ink is slightly acidic (blue ink)].

Aluminum boiling layer after the mysterious disappearance of reasons:

Three, adhesives manufacturers

Basic neutral pH of adhesives or other components that may react with aluminum.

Four, aluminum manufacturer

Vacuum evaporation adsorption on the surface of PET is pure aluminum, naked will be oxidized in air, moisture will be oxidized.

Five, expert advice

Aluminum as monomer exists Shi surface will has a layer alumina cover, aluminum although is more lively metal, but aluminum and water reaction compared difficult, reasons is aluminum and water reaction generated real one of is difficult dissolved real Al (OH), (in heating conditions Xia, aluminum hydroxide also will into for alumina), difficult dissolved real aluminum hydroxide (alumina) became a film cover in aluminum of surface on will block aluminum further and water of reaction. Heat or (and) other media (such as CL-ion) reaction in the presence will intensify. Between aluminium and water to form micro-magnetic field may also be contributing to its response.

More exposure to substances, may also form complexes of aluminium.

Aluminum boiling layer after the mysterious disappearance of reasons:

Six, speculation

Due to the thin aluminum layer (300 ~500), react with any substance can affect the apparent effect. Whether product is a natural place or boiled, the aluminum layer of damp and film itself is almost the same oxidation state. Inference is aluminum and solvents in the water or boiled is a reaction on the penetration of moisture, and other media just played a role in fueling the reaction products of qualitative analysis to be further.
