检测方法
The following is a detailed description of the test method for the common performance parameters to be tested for phenylpropanoid 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: Particle size analyzer was used to measure the size distribution of particles in the phenylpropanoid emulsion.
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.
