柔性乳液应测试哪些性能? 检测方法有哪些?
柔性乳液是以柔性聚合物为主要成分的乳液. It is different from the traditional emulsion, it has excellent flexibility, 耐刮擦性, 耐水性, 耐用性, elasticity and other characteristics. Common flexible polymers include acrylate copolymers, neoprene, silicone rubber, polyurethane, ETC. Flexible emulsion is widely used in plastics, 建筑材料, 纺织品, 电子产品, 汽车, 医疗等领域, can be used to prepare a variety of high-performance materials, 涂料, 粘合剂, sealing materials, 弹性体, ETC.

检测方法
The following is a brief description of the test methods for common performance parameters of flexible emulsions:
固含量: The coating sample was dried to a constant weight at about 105 °C, 计算非挥发性物质的质量与样品总质量的比值.
粘度: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
粒度分布: Devices such as particle size analyzers are used to measure the size distribution of particles in flexible emulsions.
PH值: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
附着力: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.
耐用性: evaluate the weather resistance, wear resistance and chemical resistance of the coating by simulating the exposure and wear tests in the actual use environment.
弹性: Use material testing machine and other equipment to measure the elasticity and deformation ability of the coating.
