Manufacturing Quality Control of Polyethylene Terephthalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Intrinsic Viscosity (IV) | Capillary Viscometry | Measures flow time of dilute polymer solution through a capillary tube to calculate IV based on relative viscosity and concentration. |
| Acid Number | Acid-Base Titration | Determines free carboxylic end groups by titration with standardized KOH solution using phenolphthalein indicator. |
| Diethylene Glycol (DEG) Content | Gas Chromatography (GC) | Quantifies DEG impurity by separation on a polar capillary column and flame ionization detection. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after complete combustion at 550-600 C in a muffle furnace. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine generated electrochemically or chemically. |
| Color (b* value) | Tristimulus Colorimetry | Measures yellowness index using CIE Lab* color space with D65 illuminant and 10-degree observer. |
| Carboxyl End Group Concentration (CEG) | Potentiometric Titration | Quantifies COOH end groups by titration with standardized KOH using pH electrode for endpoint detection. |
| Metal Impurities (e.g., Co, Mn, Sb) | ICP-OES | Determines trace metal catalyst residues by plasma excitation and emission intensity measurement at element-specific wavelengths. |
| Number Average Molecular Weight (Mn) | Gel Permeation Chromatography (GPC) | Estimates molecular weight distribution by size-based separation in porous columns with refractive index detection. |
| Melting Point | Differential Scanning Calorimetry (DSC) | Detects endothermic melting transition temperature and enthalpy by controlled heating and heat flow comparison. |
| Bulk Density | Volumetric Weighing | Measures mass per unit volume of freely poured resin particles using standardized cylinder and balance. |
| Particle Size Distribution | Sieve Analysis | Determines granulometric profile by mechanical separation through a series of standardized mesh sieves. |
