Industrial Applications of Sodium poly[(naphthaleneformaldehyde)sulfonate]
| Industry | Application | Process |
|---|---|---|
| Concrete admixtures | High-efficiency water reducer, improving concrete workability and compressive strength | Added during concrete mixing alongside other components (e.g., cement, aggregates, water); typical dosage is 0.1–0.75% by mass of cement |
| Dyes and dyeing auxiliaries | Dispersant for grinding and stabilization of disperse and vat dyes | Wet-milled with dye powder to form a stable suspension, preventing agglomeration and sedimentation of dye particles |
| Pesticide formulations | Dispersant and wetting agent in suspension concentrates (SC) and water-dispersible granules (WDG) | Mixed with active ingredients, wetting agents, and fillers during pesticide processing, followed by spray drying or wet granulation to produce solid formulations |
| Ceramic industry | Green-body strength enhancer and glaze dispersant | Added to ceramic slips or glazes to reduce viscosity, increase solids loading, and improve slip casting performance and glaze uniformity |
| Water treatment | Scale and dispersion inhibitor (co-component) in industrial recirculating cooling water systems | Used in combination with other scale inhibitors (e.g., polycarboxylates, phosphonates) to suppress deposition of inorganic scales such as calcium carbonate and calcium sulfate |
Manufacturing Quality Control of Sodium poly[(naphthaleneformaldehyde)sulfonate]
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample on a white background and observe its color, physical state (e.g., powder, granules), and whether it is clumped or contains impurities. Typically appears as a free-flowing brownish-yellow to brown powder. |
| Non-Volatile Content | Drying Weight Loss Method (GB/T 8077-2012) | Weigh a specified amount of sample and dry it in an oven at 105±2°C until constant weight is achieved; calculate the percentage of solid residue relative to the original sample mass. |
| pH Value | pH Meter Method | Dissolve the sample to a specified concentration (e.g., 10% aqueous solution) and measure its pH at 25°C using a calibrated pH meter; typically ranges from 7 to 9. |
| Surface Tension | Platinum Ring Method or Drop Volume Method | Measure the surface tension of a specified concentration aqueous solution using a tensiometer to evaluate dispersibility. Lower values indicate better surface activity. |
| Dispersibility (Cement Paste Flowability) | Cement Paste Flow Test (Refer to GB/T 8077) | Mix the sample with standard cement and water to prepare cement paste; measure initial and 30-minute flow values to assess its dispersing capability. |
| Sodium Sulfate Content | Gravimetric Method or Ion Chromatography | Precipitate sulfate ions with barium chloride, filter, dry, and weigh the precipitate (gravimetric method); or quantitatively determine SO₄²⁻ concentration using ion chromatography. |
| Total Alkali Metal Sulfate Content | Residue After Ignition + Calculation | Ignite the sample at high temperature, measure the mass of the residue, and calculate the total content of inorganic salts such as sodium sulfate based on non-volatile content and other parameters. |
| Naphthalene-Based Polymer Structure Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Perform infrared scanning on the sample and analyze characteristic absorption peaks (e.g., sulfonate group —SO₃⁻, aromatic ring C=C bonds) to confirm molecular structure. |
| Average Molecular Weight | Gel Permeation Chromatography (GPC) | Use an aqueous-phase GPC system with sodium polystyrene sulfonate as the calibration standard to determine molecular weight distribution and number-average/weight-average molecular weights. |
| Chloride Ion Content | Ion Chromatography or Silver Nitrate Titration | Dissolve the sample in water and directly measure Cl⁻ concentration using ion chromatography; or titrate with standardized AgNO₃ solution and calculate chloride content. |
| Heavy Metal Content (e.g., Pb, As) | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine concentrations of heavy metals such as lead and arsenic using AAS or Inductively Coupled Plasma Mass Spectrometry (ICP-MS). |
