The ISO-Thermal Process
The Iso-Thermal Process is a collaboration of Cargill and Kohler Coating, bringing together the best of Cargill’s rheology control and adhesive technology and Kohler’s patent pending thin film metering technology.
The Iso-Thermal Process is a patent pending corrugating process that optimizes paper moisture and temperature in order to maximize board performance and quality.
Plants who are currently operating The Iso-Thermal Process are experiencing these results:
• Ability to accurately control temperature and moisture
• 35% reduction in energy usage
• 50% reduction in total adhesive consumption
• 1-2% reduction in overall waste
• 8-10% increase in average speed and production
How It Works
The Iso-Thermal Process can be applied by following 3 simple steps.
1. Apply water to the bonding side of the liners and medium with Kohler’s WaterDeck, upstream from the heat source.
2. Apply heat to the same side as the water, using the steam flashed off to transfer heat and moisture that is now conditioning the paper.
3. Use Cargill’s FastBreak Rheology modified adhesive to optimize low energy bonding characteristics.
The WaterDeck coats the paper with a very precise thin layer of water in a process called Thin Film Metering that controls paper temperatures to prevent damage to paper fibers, reduces the water required from the starch mix and takes advantage of the high heat capacity of water to include ideal conditions for bonding. As water evaporates from paper in a moisture range from 14% down to 6%, the paper stays in the evaporation range of 185-195°F regardless of how much heat is applied.
FastBreak is Cargill’s liquid Rheology modifier. It facilitates smoother, more uniform adhesive film development, reduction of solids, and extreme reduction of glue gaps. FastBreak also gives you a shorter but thicker glue line that will not migrate away from the flute tip.
