Која својства треба испитати за фенилпропаноидну емулзију? Како открити?
Фенилпропаноидна емулзија је полимерна емулзија, главна компонента је фенилпропаноид, it is obtained by free radical polymerization of phenylpropanoid monomer emulsion. Phenylacrylic emulsion can be used to prepare various polymer materials, such as coatings, лепкова, paper coatings, asphalt modifiers, итд., with high durability, хемијска отпорност, anti-ultraviolet performance and other advantages, so it has been widely used in construction, automobile, текстилне, electronics and other fields.

Метода детекције
The following is a detailed description of the test method for the common performance parameters to be tested for phenylpropanoid emulsions:
Садржај чврсте материје: The coating sample was dried to a constant weight at about 105 ° Ц, and the ratio of the mass of non-volatile substances to the total sample mass was calculated.
Вискозност: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
Расподела величине честица: Particle size analyzer was used to measure the size distribution of particles in the phenylpropanoid emulsion.
пХ вредност: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
Adhesion: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.

Durability: 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, transportation and use.
North and South Tide remind you: различити параметри перформанси могу захтевати различите методе испитивања и опрему, и можда постоје неки индустријски стандарди и спецификације, for the performance test of phenylpropane emulsion, you should also choose the corresponding test methods and standards according to the actual needs. Истовремено, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
