Welche Eigenschaften sollten für flexible Emulsionen getestet werden?? Welche Erkennungsmethoden gibt es??
Eine flexible Emulsion ist eine Art Emulsion mit flexiblem Polymer als Hauptbestandteil. It is different from the traditional emulsion, it has excellent flexibility, scratch resistance, Wasserbeständigkeit, Haltbarkeit, elasticity and other characteristics. Common flexible polymers include acrylate copolymers, neoprene, silicone rubber, polyurethane, usw. Flexible emulsion is widely used in plastics, Baumaterial, Textil-, Elektronik, Automobil, medizinische und andere bereiche, can be used to prepare a variety of high-performance materials, Beschichtungen, Klebstoffe, sealing materials, elastomers, usw.
Erkennungsleistung
The following are the common performance parameters to be tested for flexible emulsions and their brief descriptions:
| Performance parameters | A brief description |
|---|---|
| Fester Inhalt | Nonvolatile components in the paint as a percentage of the total weight |
| Viskosität | The viscosity of the coating has an important impact on the coating effect and construction performance |
| Partikelgrößenverteilung | Size distribution of particles in a flexible emulsion |
| PH Wert | The pH of the flexible emulsion has an important influence on the stability and performance of the coating |
| Adhäsionskraft | Adhesion between coating and substrate surface |
| Haltbarkeit | The weather resistance, wear resistance and chemical resistance of the coating have an important impact on the service life and performance of the coating |
| Elastizität | The elastic and deformable ability of coatings is of great significance for flexible materials and elastomers |
| Zugfestigkeit | The maximum capacity of the coating under tensile force |
| Kratzfestigkeit | The ability of the coated surface to resist scratching and abrasion |
| Wasserbeständigkeit | Waterproof, moisture-proof and penetration-resistant properties of the coating |

Erkennungsmethode
The following is a brief description of the test methods for common performance parameters of flexible emulsions:
Fester Inhalt: 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.
Viskosität: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
Partikelgrößenverteilung: Devices such as particle size analyzers are used to measure the size distribution of particles in flexible emulsions.
PH Wert: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
Adhäsion: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.
Haltbarkeit: evaluate the weather resistance, wear resistance and chemical resistance of the coating by simulating the exposure and wear tests in the actual use environment.
Elastizität: Use material testing machine and other equipment to measure the elasticity and deformation ability of the coating.

Zugfestigkeit: Use equipment such as tensile testing machine to measure the maximum capacity of the coating under tensile force.
Kratzfestigkeit: 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.
Wasserbeständigkeit: Use water immersion tester and other equipment to evaluate the waterproof, moisture-proof and permeability resistance of the coating.
Wir erinnern Sie daran: 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. Gleichzeitig, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
