Method of continuously spraying liquids onto lengthy bodies moving at high speed

摘要

An electrostatic preventive film or silicone film is applied to the surface of elongated substrates by spraying the substance while in a liquid state, substrate while it is moving at a high speed. The surface tension of the liquid is adjusted and then the surface tension adjusted liquid substance is jet sprayed into a fine particle production chamber and at the same time applied against a vertical impingement plate installed inside the chamber for the sake of producing fine particles smaller than 10 mu . The fine particles thus produced are stored inside an accumulator tank for raising its concentration to a higher level, then the highly concentrated fine particles are given kinetic energy, thus providing the method of spraying onto the surface of the moving substrate.
