1. Performance and Application
- TPD‑116 special scale inhibitor for papermaking black‑liquor evaporator is compounded with surfactants, dispersants and viscosity‑reducers. After being dosed into papermaking black liquor, its viscosity‑reducer components react with silicon, oxalates and various saccharides inside black liquor to eliminate stickiness and keep substances suspended in black liquor.
- This inhibitor maximizes dispersion of calcium, magnesium, silicon and other scale‑forming ions within black liquor, improving anti‑sedimentation performance and fluidity. It prevents deposits and adhesion on evaporator surfaces and keeps evaporator scale‑free.
- It chemically reacts with existing scale deposits on evaporator surfaces to dissolve and strip aged scale, meanwhile inhibiting new‑scale formation. It improves heat‑transfer efficiency, accelerates water evaporation rate of black liquor and shortens evaporation cycle, bringing remarkable energy‑saving benefits for alkali‑recovery process.
