纯丙烯酸乳液需要测试哪些性能?
纯丙烯酸乳液是一种水性聚合物涂料, 由甲基丙烯酸甲酯组成 (综合格斗) 和丙烯酸丁酯 (学士) and other monomers, and is an environmentally friendly coating without volatile organic solvents. Pure acrylic emulsion has excellent water resistance, 耐候性, scratch resistance and good adhesion, and has a good gloss and flatness. Pure acrylic emulsion is widely used in indoor and external wall coating, 地坪涂料, 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.

检测方法
The following are common test methods for pure acrylic emulsion:
固含量: Use oven drying method, centrifugal method and other methods to test the content of solids in the paint.
干燥时间: Use equipment such as a drying time tester to measure the drying time of the coating.
耐水性: The water resistance of the coating is tested by means of water immersion, water mist, water drop, ETC.
耐候性: The UV resistance and corrosion resistance of the coating are tested by artificial accelerated aging test or natural weather exposure.
附着力: The combination degree between the coating and the substrate is tested by means of grid method, stripping method, stretching method, ETC.
光泽度: Use equipment such as a gloss meter to test the gloss of the coated surface.
平整度: Test the flatness and smoothness of the coating surface using parallel plate method, optical microscope and other equipment.
