Pulp Deposit Formation/Corrosion Prevention TRIZ Cases
- Enzymatic VFA Control in Papermaking Starch Water Loops
A non-biocidal enzyme treatment suppresses VFA formation in papermaking water loops, reducing odor, starch loss, and corrosion.
- Amphoteric Polymer Pitch Control Agent for High-pH Papermaking
Copolymer with specific cationic and anionic monomers prevents micro-pitch agglomeration in high-pH pulping environments.
- Hydrophobically Modified Polyethylene Glycol for Pitch and Stickies Control
Hydrophobically modified polyethylene glycol resists hydrolysis and maintains low viscosity to control pitch and stickies in recycled fiber processing.
- Amphoteric Polyacrylamide for Paper Deposit Control
Amphoteric polyacrylamide binds hydrophobic contaminants to fibres, preventing microstickies and pitch accumulation that causes web breakages.
- Black Liquor Viscosity Control via Polymer Salt Additives
Polymer-salt additives reduce black liquor viscosity to 15-50 cP, preventing scale deposition during high solids concentration evaporation.
- Lignin Scale Removal in Lignocellulosic Reactors
Alkali solution treatment at 140 to 250 C dissolves lignin scale, reducing cleaning downtime and maintaining slurry flow.
- Biofilm Control Compounds in Cellulosic Fibre Processes
Formula I compounds constrain microbial growth in high-temperature cellulosic fibre processes, preventing biofilm accumulation on process surfaces.
