Antirust Counter Board To Roll Cigarette Connecting Paper In Filter Matching Machine Max s
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.
Regular Blackened Rolling Blocks are for 7.8*84mm cigarettes, MK8D model. Please provide detailed info. to us if your desired specs is different.
Depending on cigarette sizes, filter sizes, filter machine model and other factors, time needed for manufacturing can vary. Thus details of product and relative lead time must be negotiated beforehand to avoid any discordance.
A standard black oxide is magnetite (Fe3O4), which is more mechanically stable on the surface and provides better corrosion protection than red oxide (rust) Fe2O3. Modern industrial approaches to forming black oxide include the hot and mid-temperature processes described below. The oxide can also be formed by an electrolytic process in anodizing. Traditional methods are described in the article on bluing.
Low temperature oxide, also described below, is not a conversion coating—the low-temperature process does not oxidize the iron, but deposits a copper selenium compound.
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.
