Blackened Rolling Block is a casting part of filter assembly machine, placed next to the rolling drum, functioning together to roll the tipping paper and connect the filter and the cigarette.
Advantages Of Blackening
Blackening can be done in large batches (ideal for small parts).
There is no significant dimensional impact (the blacking process creates a layer about a micrometre thick).
It is far cheaper than similar corrosion protection systems, such as paint and electroplating.
Hot Blackening
Hot blackening involves dipping the part into various tanks. The work piece is usually "dipped" by automated part carriers for transportation between tanks. These tanks contain, in order, alkaline cleaner, water, caustic soda at 140.5 °C (284.9 °F) (the blackening compound), and finally the sealant, which is usually oil. The caustic soda bonds chemically to the surface of the metal, creating a porous base layer on the part. Oil is then applied to the heated part, which seals it by "sinking" into the applied porous layer. It is the oil that prevents the corrosion of the workpiece.
Hot Black Oxide
Hot baths of sodium hydroxide, nitrates, and nitrites at 141 °C (286 °F) are used to convert the surface of the material into magnetite (Fe3O4). Water must be periodically added to the bath, with proper controls to prevent a steam explosion.
