Manufacturing Quality Control of ANTIFOAM PE-L
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, clarity, and presence of suspended particles or precipitates under natural or standard lighting. The sample should be a colorless to pale yellow clear liquid. |
| Color Number (Hazen) | Platinum-Cobalt Colorimetric Method (GB/T 3143) | Compare the sample with standard platinum-cobalt solutions to determine its color value, used to assess product purity and detect oxidation or impurity contamination. |
| Hydroxyl Value | Acetylation Method (GB/T 7383 or ASTM D4274) | Determine hydroxyl group content via acetic anhydride acetylation reaction, calculate hydroxyl value (mg KOH/g), reflecting molecular weight and functionality. |
| Acid Value | Acid-Base Titration (GB/T 2895 or ASTM D974) | Titrate free acids in the sample using a standardized potassium hydroxide ethanol solution, expressed as mg KOH/g, to evaluate product stability and potential acid spoilage during storage. |
| Water Content | Karl Fischer Titration (GB/T 6283 or ASTM E203) | Determine water content using volumetric or coulometric Karl Fischer reagent titration, controlling moisture impact on downstream application performance. |
| Density | Densimeter or Pycnometer Method (GB/T 4472) | Measure the sample’s density at a specified temperature (e.g., 20°C or 25°C), used as an auxiliary parameter to assess purity and batch consistency. |
| Refractive Index | Abbe Refractometer Method (GB/T 6488) | Measure the refractive index at a specific temperature (e.g., 20°C) as an auxiliary indicator for composition consistency and impurity detection. |
| Boiling Range/Distillation Range | Distillation Method (GB/T 7534 or ASTM D1078) | Determine initial boiling point, final boiling point, and distillation temperature range under atmospheric or reduced pressure, evaluating volatility and component distribution. |
| Average Molecular Weight | Gel Permeation Chromatography (GPC) or End-group Analysis | GPC measures molecular weight distribution; alternatively, number-average molecular weight can be calculated from hydroxyl value (Mn = 56.1×1000×f / OH#, where f is functionality). |
| Purity/Main Component Content | Gas Chromatography (GC, ASTM D2710) | Use capillary column GC to separate and quantify main components and impurity peaks, calculating purity percentage to assess completeness of synthesis reaction. |
| pH (aqueous solution) | pH Meter Method (GB/T 9724) | Prepare a solution of defined concentration in water and measure its acidity/basicity using a calibrated pH meter to evaluate residual catalysts or by-products. |
