Benefits of technology

This patented technology allows for an efficient way to make materials that are resistive against fire damage without releasing dangerous or potentially damaging chemical compounds like formalin (formaldehydes). It also includes various methods used during manufacturing processes to simplify its making steps, reduce costs, increase productivity, enhance durability, and prevent contamination from other components within the structure being protected by this protecting layer. Additionally, it suggests adding nanoparticles with specific properties into coatings to further strengthen their effectiveness at providing protection over longer periods of time. Overall, these technical results help create safer buildings more efficiently.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the quality of fibre materials used in various industries like construction or transportation that can cause damage from exposure during their usage. To solve it, researches aimed at developing better fire retardant composites made up mostly of organic polymer matrices instead of pure natural wood pulp (WPC) were conducted over several decades ago. These improved properties make them safer than regular WPM-based products while still maintaining its strength and durability.
