Quais propriedades devem ser testadas para emulsão acrílica pura?

A emulsão acrílica pura é um revestimento de polímero à base de água, que é composto de metacrilato de metila (MMA) e acrilato de butila (BA) and other monomers, and is an environmentally friendly coating without volatile organic solvents. Pure acrylic emulsion has excellent water resistance, resistência às intempéries, 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.

Método de detecção
The following are common test methods for pure acrylic emulsion:

Conteúdo sólido: Use oven drying method, centrifugal method and other methods to test the content of solids in the paint.

Tempo de secagem: Use equipment such as a drying time tester to measure the drying time of the coating.

Resistência à água: The water resistance of the coating is tested by means of water immersion, water mist, water drop, etc..

Resistência às intempéries: The UV resistance and corrosion resistance of the coating are tested by artificial accelerated aging test or natural weather exposure.

Adesão: The combination degree between the coating and the substrate is tested by means of grid method, stripping method, stretching method, etc..

Lustro: Use equipment such as a gloss meter to test the gloss of the coated surface.

Flatness: Test the flatness and smoothness of the coating surface using parallel plate method, optical microscope and other equipment.

Scratch resistance: The scratch resistance of the coating surface is tested by scratch test.

Solidez da cor: Use equipment such as a color meter to test the color difference and color fastness of the coating.

Other: 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, viscosidade, pH value of the coating.

Maré Norte e Sul lembra você: 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.
