Какие свойства следует проверять эластичных эмульсий? Какие существуют методы обнаружения?
Гибкая эмульсия – это разновидность эмульсии, основным компонентом которой является гибкий полимер.. It is different from the traditional emulsion, it has excellent flexibility, устойчивость к царапинам, Водонепроницаемый, долговечность, elasticity and other characteristics. Common flexible polymers include acrylate copolymers, neoprene, silicone rubber, полиуретан, и т. д.. Flexible emulsion is widely used in plastics, строительные материалы, текстиль, электроника, автомобильный, медицина и другие области, can be used to prepare a variety of high-performance materials, покрытия, клеи, sealing materials, эластомеры, и т. д..

Метод обнаружения
The following is a brief description of the test methods for common performance parameters of flexible 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: Devices such as particle size analyzers are used to measure the size distribution of particles in flexible emulsions.
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.
Эластичность: Use material testing machine and other equipment to measure the elasticity and deformation ability of the coating.

Предел прочности: Use equipment such as tensile testing machine to measure the maximum capacity of the coating under tensile force.
Устойчивость к царапинам: Use equipment such as a scratch resistance meter to simulate the scratch and wear in actual use, and evaluate the scratch resistance of the coating surface.
Водонепроницаемый: Use water immersion tester and other equipment to evaluate the waterproof, moisture-proof and permeability resistance of the coating.
Мы напоминаем вам: разные параметры производительности могут потребовать разных методов испытаний и оборудования., и могут существовать некоторые отраслевые стандарты и спецификации, for flexible emulsion performance testing, but also should be selected according to the actual needs of the corresponding test methods and standards. 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.
