Latest Patents

Rigal holds a patent for a method of production of lignocellulosic composite materials. This method involves several key steps: first, providing a straw plant material with fibers surrounded by a waxy and silica layer. Next, the straw is extruded in a twin screw extruder while undergoing thermal treatment with an aqueous solution containing a lignin modifying agent or steam. This process occurs at temperatures between about 40°C and 120°C, allowing for substantial defibration of the straw material. Finally, the treated material is subjected to heat and pressure in the presence of a formaldehyde-based resin to create a resin-bonded fiberboard or particleboard. Rigal's innovative method is a significant advancement in the field of composite materials.
