Manufacturing Quality Control of POLY(STYRENE-CO-DIVINYLBENZENE)
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection / Optical Microscopy | Inspect the color, shape, transparency, and presence of impurities or cracks in resin particles using naked eye or microscope observation. |
| Particle Size and Particle Size Distribution | Laser Particle Size Analyzer / Sieving Method | The laser particle size analyzer determines particle size distribution by measuring scattered light; the sieving method classifies particles by size using standard sieves, with weight percentages calculated to determine distribution. |
| Moisture Content | Karl Fischer Titration / Gravimetric Drying Loss Method | Karl Fischer titration is specifically used for quantitative water determination; the gravimetric drying loss method calculates moisture content based on mass loss after drying samples at a specified temperature. |
| Divinylbenzene (DVB) Content | Proton Nuclear Magnetic Resonance (¹H NMR) / Elemental Analysis | ¹H NMR calculates the ratio of styrene to DVB monomers via integration of characteristic peaks; elemental analysis estimates crosslinking degree indirectly from carbon and hydrogen content. |
| Specific Surface Area | BET Nitrogen Adsorption Method | Measures nitrogen adsorption isotherms on the resin surface at liquid nitrogen temperature, and calculates specific surface area (m²/g) using the BET equation. |
| Pore Structure (Pore Diameter, Pore Volume) | Mercury Intrusion Porosimetry / Nitrogen Adsorption-Desorption Isotherm | Mercury intrusion porosimetry is suitable for large pore analysis; nitrogen adsorption is ideal for micropores and mesopores, with pore size distribution and volume determined using BJH or DFT models. |
| Mechanical Strength (Abrasion Resistance) | Oscillatory Wear Test / Crushing Strength Test | Resin particles are placed in an oscillating apparatus to simulate operational conditions, and changes in particle size before and after wear are measured; alternatively, crushing strength is evaluated by applying pressure until particle fracture occurs. |
| Functional Group Content (if modified) | Acid-Base Titration / Elemental Analysis / Infrared Spectroscopy | For modified PS-DVB resins such as sulfonated or aminated types, acid/base capacity is determined by titration; infrared spectroscopy identifies functional groups qualitatively; elemental analysis supports quantitative assessment. |
| Residual Monomer Content | Gas Chromatography (GC) / High-Performance Liquid Chromatography (HPLC) | Unreacted styrene, DVB, and other monomers are extracted from the sample and quantified using GC or HPLC. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Monitors mass change of the sample under programmed temperature control to evaluate decomposition temperature and thermal stability. |
| Swellability | Solvent Immersion Method | Dry resin is immersed in a specific solvent (e.g., toluene, water), and equilibrium swelling ratio (percentage increase in volume or mass) is measured. |
