Які властивості слід перевірити для чистої акрилової емульсії?
Чиста акрилова емульсія - це полімерне покриття на водній основі, який складається з метилметакрилату (ММА) і бутилакрилат (BA) and other monomers, and is an environmentally friendly coating without volatile organic solvents. Pure acrylic emulsion has excellent water resistance, weather resistance, 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.

Спосіб виявлення
The following are common test methods for pure acrylic emulsion:
Солідний вміст: Use oven drying method, centrifugal method and other methods to test the content of solids in the paint.
Час висихання: Use equipment such as a drying time tester to measure the drying time of the coating.
Водотривкість: The water resistance of the coating is tested by means of water immersion, water mist, water drop, тощо.
Погодостійкість: The UV resistance and corrosion resistance of the coating are tested by artificial accelerated aging test or natural weather exposure.
Адгезія: The combination degree between the coating and the substrate is tested by means of grid method, stripping method, stretching method, тощо.
Gloss: Use equipment such as a gloss meter to test the gloss of the coated surface.
площинність: Test the flatness and smoothness of the coating surface using parallel plate method, optical microscope and other equipment.
