Какие свойства следует проверить фенилпропаноидной эмульсии? Как обнаружить?
Фенилпропаноидная эмульсия представляет собой полимерную эмульсию., основной компонент – фенилпропаноид, it is obtained by free radical polymerization of phenylpropanoid monomer emulsion. Phenylacrylic emulsion can be used to prepare various polymer materials, такие как покрытия, клеи, paper coatings, asphalt modifiers, и т. д., with high durability, химическая устойчивость, anti-ultraviolet performance and other advantages, so it has been widely used in construction, автомобиль, текстиль, электроника и другие области.

Метод обнаружения
The following is a detailed description of the test method for the common performance parameters to be tested for phenylpropanoid emulsions:
Солидный контент: The coating sample was dried to a constant weight at about 105 °С, и рассчитывали отношение массы нелетучих веществ к общей массе пробы.
Вязкость: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
Распределение частиц по размерам: Particle size analyzer was used to measure the size distribution of particles in the phenylpropanoid emulsion.
значение pH: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
Адгезия: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.

Долговечность: 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, транспортировка и использование.
Северный и Южный прилив напоминают вам: разные параметры производительности могут потребовать разных методов испытаний и оборудования., и могут существовать некоторые отраслевые стандарты и спецификации, for the performance test of phenylpropane emulsion, you should also choose the corresponding test methods and standards according to the actual needs. В то же время, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
