Quelles propriétés doivent être testées pour l'émulsion de phénylpropanoïde? Comment détecter?
L'émulsion phénylpropanoïde est une émulsion polymère, le composant principal est le phénylpropanoïde, it is obtained by free radical polymerization of phenylpropanoid monomer emulsion. Phenylacrylic emulsion can be used to prepare various polymer materials, such as coatings, adhésifs, paper coatings, asphalt modifiers, etc., with high durability, chemical resistance, anti-ultraviolet performance and other advantages, so it has been widely used in construction, voiture, textile, électronique et autres domaines.
Performances de détection
The following are the common performance parameters that need to be tested for phenylpropane-acrylic emulsion and their brief descriptions, as detailed in the following table:
| Performance parameters | Une brève description |
|---|---|
| Du contenu solide | Nonvolatile components in the paint as a percentage of the total weight |
| viscosity | The viscosity of the coating has an important impact on the coating effect and construction performance |
| Distribution granulométrique | Particle size distribution in phenylpropanoid emulsion |

Méthode de détection
The following is a detailed description of the test method for the common performance parameters to be tested for phenylpropanoid emulsions:
Du contenu solide: The coating sample was dried to a constant weight at about 105 °C, et le rapport entre la masse de substances non volatiles et la masse totale de l'échantillon a été calculé.
Viscosité: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
Distribution granulométrique: Particle size analyzer was used to measure the size distribution of particles in the phenylpropanoid emulsion.
PH: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
Adhésion: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.

Durabilité: evaluate the weather resistance, wear resistance and chemical resistance of the coating by simulating the exposure and wear tests in the actual use environment.
Emulsion stability: The emulsion stability of the coating is evaluated by analyzing the stability and dispersion of the phenylpropane-acrylic emulsion during storage, transport et utilisation.
North and South Tide remind you: différents paramètres de performance peuvent nécessiter différentes méthodes et équipements de test, et il peut y avoir certaines normes et spécifications de l'industrie, for the performance test of phenylpropane emulsion, you should also choose the corresponding test methods and standards according to the actual needs. En même temps, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
