There are two methods available: Thermal Disinfection and Chemical Disinfection.

In these cases, chemical etching is the preferred method.

The cavity mask is used for etching into the intermediate oxide layer (1), causing the formation of a recess (8').

Electrical assistance is unnecessary during the chemical etching of the invention, which may be conducted in the presence or absence of illumination.

Most Effective way is to use a chemical paint remover to remove multiple layers of old paint.

The invention further relates to treatment methods and compositions for surface treatments such as descaling, pickling and removing surface deposits and corrosion products.

Steel pickling is the process by which iron oxides and scale are removed from the surface of steel by converting the oxides to soluble compounds.

There are two methods available: Thermal Disinfection and Chemical Disinfection.

The device may be used specifically in chemical pickling installations for metal sheet.

In these cases, chemical etching is the preferred method.

Either PT, after a chemical etching, when possible.

Formaldehyde – A “pickling” chemical used to preserve cadavers.

Formaldehyde - A "pickling" chemical used to preserve cadavers.

The chemical cycle (the pickling) is based on hydrochloric acid (HCL).
