Manufacturing Quality Control of Pentaerythritol tetraacrylate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color, transparency, and presence of impurities under natural light or standard lighting. |
| Color (APHA) | Platinum-Cobalt Colorimetry (GB/T 3143 or ASTM D1209) | Use a colorimeter or visual color comparison tubes to compare the sample with platinum-cobalt standard solutions to determine its color intensity and assess purity. |
| Purity (Main Component Content) | Gas Chromatography (GC) | Use a capillary column gas chromatograph to identify components by retention time and quantify the main component content using peak area normalization or internal standard method. |
| Acrylic Monomer Residue | Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) | Detect unreacted acrylic monomers or other impurities. The internal standard method is often used to improve quantitative accuracy. |
| Moisture Content | Karl Fischer Titration | Quantitatively react iodine and sulfur dioxide in methanol with water and determine trace moisture content by potentiometric titration. |
| Functional Group Analysis (Double Bond Content) | Iodine Value Method or Fourier Transform Infrared Spectroscopy (FTIR) | The iodine value method determines unsaturation through an addition reaction; FTIR confirms the presence of acrylic ester double bonds via characteristic absorption peaks (e.g., =C-H bending vibration at 810 cm⁻¹). |
| Viscosity | Rotational Viscometer Method (GB/T 2794 or ISO 2555) | Measure the flow resistance of the liquid using a rotational viscometer under constant temperature conditions to reflect product processability. |
| Acid Value | Acid-Base Titration (GB/T 6680 or ASTM D974) | Titrate free acids in the sample with a standard potassium hydroxide ethanol solution and calculate the milligrams of KOH consumed per gram of sample. |
| Density | Densitometer Method or Pycnometer Method (GB/T 4472) | Directly measure using a densitometer or accurately calculate mass per unit volume using a pycnometer. |
| Volatile Content | Thermogravimetric Analysis (TGA) or Oven Weight Loss Method | Heat the sample at a specified temperature and measure the weight loss to evaluate volatile impurities or solvent residues. |
