Hot Black Oxide Cigarette Wrapping Paper Connecting Block Of Filter Assembler Machine Molins Max

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.

Customization

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.

Room-Temperature Blackening

Room-temperature blackening for stainless steel occurs by auto-catalytic reaction of copper-selenide depositing on the stainless-steel surface. It offers less abrasion resistance and the same corrosion protection as the hot blackening process. One application for room-temperature blackening is in architectural finishes (patina for stainless steel).

Ferrous Materials

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.
