Solutions
A groundbreaking research project has emerged in Canada, addressing a significant challenge by introducing alkylated phosphorylated fibers as a solution for release paper production. This breakthrough offers both environmental sustainability and cost-effectiveness.
The process involves several crucial stages:
- Enhancing Cellulosic Fibers: Researchers utilized phosphate esters within molten urea to phosphorylate old corrugated cardboard (OCC) fibers.
- Fiber Modification: The phosphorylated fibers underwent alkylation, involving acid chlorides and a mild base.
- Coating Solution Formulation: A specialized coating solution was developed, incorporating the alkylated phosphorylated fibers according to a specific composition outlined in the provided table.
- Application of Coating: The formulated coating solution was applied to OCC sheets using a variable speed drawdown coater. This was done at room temperature and atmospheric pressure, with the coater’s speed set to 10 m/min.
