Cellulose-based filter media are affected by the degree of paper saturation because it affects their absorbency and physical properties. The degree of paper saturation also affects cellulose-based filter media in terms of stiffness, durability and opacity. Higher levels of saturation make these materials stiffer, which can be beneficial for certain industrial applications that require high levels of pressure resistance.
Additionally, highly saturated papers are more durable and less prone to tearing or puncturing, making them ideal for long-term filtration purposes.
GESSNER impregnates its special technical papers using a process based on methanol or water. Impregnating with phenolic, epoxy, acrylic resins or latex gives high strength, dimensional stability and improves resistance to solvents, chemicals and high temperatures.
Special additives, depending on need, can be added to give further functionality. For example, hydrophobic, hydrophilic or oleophobic properties, flame retardancy, various colors, UV stability, bactericides, fungicides, etc, can all be built-in. Using further coating devices, we can add still further functionalities.
GESSNER's ability of an asymmetric saturation process provides many different functionalities of cellulose-based media. Utilising an asymmetric saturation process is essential for ensuring that impregnation filter media can provide optimal filtration capabilities when used in a range of industrial settings, especially when it comes to customized and very special requirements. GESSNER mentions below only a few examples of what is possible by using this special process.
