Які властивості необхідно перевірити для гнучких емульсій? Які є методи виявлення?
Гнучка емульсія - це різновид емульсії з гнучким полімером як основним компонентом. It is different from the traditional emulsion, it has excellent flexibility, стійкість до подряпин, водотривкість, довговічність, elasticity and other characteristics. Common flexible polymers include acrylate copolymers, neoprene, silicone rubber, polyurethane, тощо. Flexible emulsion is widely used in plastics, building materials, текстиль, електроніка, автомобільний, medical and other fields, can be used to prepare a variety of high-performance materials, покриття, клеї, sealing materials, elastomers, тощо.

Спосіб виявлення
The following is a brief description of the test methods for common performance parameters of flexible emulsions:
Солідний вміст: The coating sample was dried to a constant weight at about 105 ° C, and the ratio of the mass of non-volatile substances to the total sample mass was calculated.
В'язкість: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
Particle size distribution: Devices such as particle size analyzers are used to measure the size distribution of particles in flexible emulsions.
pH value: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
Адгезія: 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.
Elasticity: Use material testing machine and other equipment to measure the elasticity and deformation ability of the coating.

Міцність на розрив: Use equipment such as tensile testing machine to measure the maximum capacity of the coating under tensile force.
Scratch resistance: 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.
Водотривкість: Use water immersion tester and other equipment to evaluate the waterproof, moisture-proof and permeability resistance of the coating.
Нагадуємо: different performance parameters may require different test methods and equipment, and there may be some industry standards and specifications, for flexible emulsion performance testing, but also should be selected according to the actual needs of the corresponding test methods and standards. В той самий час, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
