Industrial Applications of Poly(propylene glycol) bis(2-aminopropyl ether)
| Industry | Application | Process |
|---|---|---|
| Wind Power | Curing agent for structural adhesives used in wind turbine blade manufacturing | Blended with epoxy resin and thermally cured to form high-strength, high-toughness composites |
| Coatings | Curing agent for high-performance anticorrosive coatings and floor coatings | Reacts with epoxy resin to form a crosslinked network, enhancing chemical resistance and abrasion resistance |
| Composites | Curing agent for epoxy-based resin matrices in carbon fiber-reinforced polymer (CFRP) composites | Formulated with epoxy resin into prepregs and cured under heat and pressure in an autoclave |
| Adhesives | Curing component for structural adhesives and electronic encapsulants | Mixed with epoxy resin at specified ratios and cured at ambient or intermediate temperatures to deliver superior bond strength and thermal resistance |
| Oil & Gas Production | Additive for cement retarders and scale inhibitors in oilfield cementing operations | Incorporated as a modified component into cement slurries to control hydration rate and suppress calcium carbonate/calcium sulfate scale formation |
| Textiles | Intermediate for fabric softeners and antistatic finishing agents | Modified via alkylation and quaternization for use in textile finishing processes to improve hand feel and electrical conductivity |
Manufacturing Quality Control of Poly(propylene glycol) bis(2-aminopropyl ether)
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color, transparency, and presence of mechanical impurities under natural light or a standard light source. |
| Amine Value (AV) | Acid-Base Titration | Titrate the polyetheramine sample with a known concentration of hydrochloric acid standard solution, using an indicator such as bromocresol green to determine the endpoint. Calculate the milligrams of KOH consumed per gram of sample (mg KOH/g). |
| Hydroxyl Value (OHV) | Acetylation Method + Titration | The sample reacts with acetic anhydride to acetylate hydroxyl groups. After completion, residual anhydride is hydrolyzed, and the generated acetic acid is titrated with a standard alkaline solution to calculate the hydroxyl value (mg KOH/g). |
| Molecular Weight Distribution | Gel Permeation Chromatography (GPC/SEC) | Utilize differences in retention time of components with different molecular weights on a gel column. Compare with standards to determine number-average molecular weight (Mn), weight-average molecular weight (Mw), and polydispersity index (PDI). |
| Viscosity | Rotational Viscometer Method | Measure the flow resistance of the sample at a specific rotational speed using a rotational viscometer under constant temperature, obtaining dynamic viscosity (mPa·s). |
| Moisture Content | Karl Fischer Titration | Based on the quantitative reaction of iodine and sulfur dioxide with water in an anhydrous environment, precisely determine trace moisture content (%) or ppm) in the sample using coulometric or volumetric methods. |
| Unsaturation (Double Bond Content) | Gas Chromatography-Mass Spectrometry (GC-MS) or Fourier Transform Infrared Spectroscopy (FTIR) | GC-MS is used to analyze terminal alkene structures; FTIR assesses the degree of unsaturation semi-quantitatively by detecting the C=C stretching vibration peak (around 1640 cm⁻¹). |
| pH Value | pH Meter Measurement | Dissolve the polyetheramine into an aqueous solution of specified concentration and measure its acidity or alkalinity using a calibrated pH meter. |
| Color | Platinum-Cobalt Color Scale (APHA Color) | Compare the sample visually or instrumentally against a standard platinum-cobalt color series to evaluate its yellowness, commonly used for appearance quality control of liquid products. |
| Purity / Impurity Analysis | High-Performance Liquid Chromatography (HPLC) or Gas Chromatography (GC) | Separate and quantify the main component and potential low-molecular-weight impurities (e.g., unreacted monomers, by-products), using calibration curves for quantitative analysis. |
