3. Concrete examples
Because the nitrogen produced by a PSA system generally contains low levels of oxygen, some chemical processes are better suited to this type of supply than others. The following examples detail processes for which the use of a PSA system has proved highly beneficial.
3.1 Production of pressure-sensitive adhesives
The manufacture of pressure-sensitive adhesives involves the handling of flammable solvents and powders, which can present safety problems. In this process, finely ground rubber and filler materials are added to flammable organic solvents in agitators. Since vapors from solvents are typically flammable in air, and grindings can generate significant sparks from the build-up of static electricity, these reactions are dangerous in the presence of air...
