Main Working Principles of TAMOL NN9104 Dispersant NNO CAS NO. 9084-06-4
The core function of TAMOL NN9104 Dispersant NNO CAS NO. 9084-06-4 is to prevent solid particles from aggregating and settling, ensuring their uniform dispersion in the liquid medium and forming a stable suspension. Its working principle mainly relies on the following points:
Adsorption:
One end of its molecular structure is a lipophilic naphthalene ring, which can firmly adsorb onto the surface of dyes or other hydrophobic particles.
Electrostatic repulsion:
The other end of the molecule is a hydrophilic sulfonic acid group (-SO₃⁻), which ionizes when dissolved in water and forms a negatively charged strong electric field on the particle surface. Since all particles carry the same charge, they repel each other, thus preventing them from approaching and aggregating.
Steric hindrance:
Its high-molecular long-chain structure forms a protective layer around the particles, creating a physical space.

Usage Method and Precautions of TAMOL NN9104 Dispersant NNO CAS NO. 9084-06-4
· Dosage:
Generally, TAMOL NN9104 Dispersant NNO CAS NO. 9084-06-4 is 0.5% to 3% of the mass of the substance to be dispersed. The specific dosage should be determined by the experiment. If the dosage is too low, the dispersion effect will be poor; if it is too high, it may affect subsequent processes (such as dyeing uptake rate).
· Dissolution:
TAMOL NN9104 Dispersant NNO CAS NO. 9084-06-4 is recommended to first stir and dissolve it in warm water (40-50°C) to form a uniform solution, and then add it to the system.
· Compatibility:
As an anionic additive, it should not be mixed with cationic additives (such as cationic softeners, fixation agents), otherwise precipitation will occur, leading to failure.
· Storage: It should be sealed and stored in a cool and dry place to prevent moisture and caking.
