| Industry | Application | Process |
|---|---|---|
| Water Treatment | Used as a scale inhibitor and dispersant to suppress formation of inorganic salt scales such as calcium carbonate and calcium sulfate | Dosed as an aqueous solution into recirculating cooling water systems, typically formulated with other water treatment chemicals (e.g., phosphonates, zinc salts) |
| Papermaking | Acts as a pulp dispersant and dispersing/stabilizing agent for fillers and pigments, improving dispersion of fillers (e.g., calcium carbonate, kaolin) in pulp suspensions | Added to pulp suspensions; pH is controlled within the range of 6–9 and used in conjunction with cationic additives |
| Textile Dyeing & Printing | Used as a dyeing auxiliary to enhance dye dispersion stability and leveling performance | Incorporated into dye baths as a dispersion-stabilizing component, commonly used synergistically with nonionic surfactants |
| Coatings | Functions as a pigment dispersant and anti-settling stabilizer to improve storage stability of coatings | Added during the grinding stage of coating manufacture; provides steric stabilization through carboxyl group interaction with pigment surfaces |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator. |
| Sodium Content | ICP-OES | Quantification of sodium ions by measuring atomic emission intensity at characteristic wavelengths after plasma atomization. |
| Residual Monomer (Acrylic Acid) | GC-FID | Separation and quantification of unreacted acrylic acid via gas chromatography with flame ionization detection. |
| Residual Monomer (Furan Dione Sodium Salt) | HPLC-UV | Separation and quantification using reversed-phase HPLC with UV detection at 210 nm. |
| Molecular Weight Distribution | GPC/SEC | Determination of weight-average (Mw) and number-average (Mn) molecular weights relative to polystyrene standards using size exclusion chromatography. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent. |
| pH (1% Aqueous Solution) | pH Meter Measurement | Direct potentiometric measurement of hydrogen ion activity in a standardized aqueous dispersion. |
| Ash Content | Gravimetric Analysis | Calcination at 550 C followed by weighing of inorganic residue after complete organic matrix removal. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled lighting conditions. |
| Viscosity (Solution) | Rotational Viscometry | Measurement of resistance to flow of a defined polymer concentration in aqueous solution at specified temperature and shear rate. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-MS | Multi-element quantification of trace metals using inductively coupled plasma mass spectrometry with isotope detection. |
| Sulfated Ash | Gravimetric Analysis | Combustion in presence of sulfuric acid followed by high-temperature ashing and residue weighing. |
