Long Functional Life Gluing Unit For Paper Adherence
Glue Applicator is a component assembled in both cigarette makers and packers, applying glue to different paper materials.
1. Pigmented versions
The adhesives are usually clear or translucent, colorless, straw-colored, tan, or amber. Pigmented versions are also made and even versions with glittery sparkles. Materials containing polar groups, aromatic systems, and double and triple bonds tend to appear darker than non-polar fully saturated substances; when a water-clear appearance is desired, suitable polymers and additives, e.g. hydrogenated tackifying resins, have to be used.
2. Polymer
Increase of bond strength and service temperature can be achieved by formation of cross-links in the polymer after solidification. This can be achieved by using polymers undergoing curing with residual moisture (e.g., reactive polyurethanes, silicones), exposure to ultraviolet radiation, electron irradiation, or by other methods.
3. Martensitic Steels
They all fall into four categories (with some overlap though)
Martensitic stainless steels ranges from a large variety of properties and are used as stainless engineering steels, stainless tool steels, and creep-resistant steels. They are all magnetic, but not as corrosion-resistant as ferritic and austenitic stainless steels because of their low chromium content.
