Quali proprietà dovrebbero essere testate per l'emulsione acrilica pura?
L'emulsione acrilica pura è un rivestimento polimerico a base d'acqua, che è composto da metil metacrilato (MMA) e butil acrilato (BA) and other monomers, and is an environmentally friendly coating without volatile organic solvents. Pure acrylic emulsion has excellent water resistance, resistenza agli agenti atmosferici, scratch resistance and good adhesion, and has a good gloss and flatness. Pure acrylic emulsion is widely used in indoor and external wall coating, floor coating, metal surface anti-corrosion coating, plastic surface coating and other fields, is a stable performance, convenient construction, environmental protection and health of high quality coating.
Prestazioni di rilevamento
| Prestazione | test item |
|---|---|
| Contenuto solido | The content of solids in the paint |
| Tempo di asciugatura | Coating drying time |
| Resistenza all'acqua | Resistenza all'acqua |
| Weather fastness | Resistenza ai raggi UV, resistenza alla corrosione, eccetera |
| Forza adesiva | The degree of bonding between coating and substrate |
| lucentezza | Gloss of the coated surface |
| flatness | The flatness and smoothness of the coating surface |
| Resistenza ai graffi | Scratch resistance of the coated surface |
| Colour fastness | Color fastness of the coating |
| other | Such as density, viscosità, valore del ph, eccetera |
The results of these test programs can help evaluate the quality and suitability of pure acrylic emulsions and how well they perform in practical applications. Test methods and equipment vary according to the specific pure acrylic emulsion type and test items.

Metodo di rilevamento
The following are common test methods for pure acrylic emulsion:
Contenuto solido: Use oven drying method, centrifugal method and other methods to test the content of solids in the paint.
Tempo di asciugatura: Use equipment such as a drying time tester to measure the drying time of the coating.
Resistenza all'acqua: The water resistance of the coating is tested by means of water immersion, water mist, water drop, eccetera.
Resistenza agli agenti atmosferici: The UV resistance and corrosion resistance of the coating are tested by artificial accelerated aging test or natural weather exposure.
Adesione: The combination degree between the coating and the substrate is tested by means of grid method, stripping method, stretching method, eccetera.
Gloss: Use equipment such as a gloss meter to test the gloss of the coated surface.
Planarità: Test the flatness and smoothness of the coating surface using parallel plate method, optical microscope and other equipment.

Resistenza ai graffi: The scratch resistance of the coating surface is tested by scratch test.
Color fastness: Use equipment such as a color meter to test the color difference and color fastness of the coating.
Altro: According to the specific type of pure acrylic emulsion and test items, choose the appropriate test method and equipment for testing, such as measuring the density, viscosità, pH value of the coating.
North and South tide reminds you: the performance test of pure acrylic emulsion needs to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results.
