Problem Statement
- Inadequate dispersion and aggregation of cellulose in solvents hinder its effective utilization as reinforcement in mold production.
- Conventional methods rely on commercial cellulose materials and high-energy processes, lacking efficiency and sustainability.
- There is a need for an improved method to utilize cellulosic waste, such as cotton microdust, for mold development, addressing dispersion issues and reducing energy consumption.
Technology
- The invention presents a novel two-step thermochemical treatment method for cotton microdust (CMD), transforming its morphology into powdery particles for improved dispersion.
- CMD is then solubilized in zinc chloride solution and combined with monosodium glutamate as a cross-linker to form molds, which are reinforced with sand fractions.
- The process ensures homogeneous mixing, controlled gelation, and efficient blending of sand without aggregation, resulting in sturdy mold structures suitable for various applications.
