Description

technical field [0001] The invention relates to a liquid drop impact experimental device, in particular to a liquid drop impact experimental device for quantitatively controlling the deformation and tension of a flexible substrate by ventilation, and belongs to the field of liquid drop impact behavior control. Background technique [0002] After the droplets hit the solid surface, they will stick, spread, rebound or even break. In industrial and agricultural production, on the one hand, it is necessary for the droplets to quickly detach or roll off the substrate surface, such as: the surface of anti-fouling products, car windshields, anti-corrosion Ice coating, etc.; on the other hand, it is required that the droplets can adhere to or even spread on the substrate surface. For example, the quality of thermal spraying depends on the adhesion of metal droplets; pesticides sprayed on plants not only require droplets to adhere to the plants, but also Spread to a certain extent to...
