Coating process: new powder coating process

Core tip: powder coating is the coating process of coating powder coating on the clean coating and baking to film Powder coating is completely different from liquid coating It does not contain solvent and dispersion medium, and does not flow itself It flows only after melting, and does not adhere to the surface of the coating like liquid coating Therefore, the traditional coating method is almost not applicable, so a new powder coating method must be used Electromagnetic brush coating Electromagnetic brush technology is composed of a complete brush table and a drum on which the material to be coated is adhered When the electrostatic field is turned on, with the substrate to be coated passing through the magnetic brush, the powder is coated on it, making the substrate several times Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: powder coating is the coating process of coating powder coating on the clean coated object and baking into film Powder coating is completely different from liquid coating It does not contain solvent and dispersion medium, and does not flow itself It flows only after melting, and does not adhere to the surface of the coating like liquid coating Therefore, the traditional coating method is almost not applicable, so a new powder coating method must be used The electromagnetic brush coating technology is composed of a complete magnetic brush table and a magnetic drum on which the materials to be coated are adhered When the electrostatic field is turned on, with the substrate to be coated passing through the magnetic brush, the powder is coated on it, making the substrate pass through the magnetic brush for many times, and the powder is coated on it, making the substrate pass through the magnetic brush for many times, a thicker coating can be obtained The process is not suitable for direct coating of ferromagnetic substrate, but the substrate can be coated by introducing a transfer step, that is, a transfer drum is used to heat or electrostatic transfer the powder to the magnetic substrate At present, polyester / TGIC white powder coating has been successfully applied to aluminum foil substrate, and UV curable powder coating has been applied to cardboard and gold printing Electric field cloud coating electric field cloud coating technology is to use air to blow the powder coating between two electrodes arranged in vertical direction, which is charged by the powder coating, and the coating process is completed by the coated workpiece between the electrodes adsorbing the powder coating The new technology is different from corona discharge and friction charge, and it is the method of powder belt point in electric field It is characterized by low voltage, high capacitance and uniform voltage application Therefore, compared with the electrostatic spray gun, it has higher spraying efficiency and can cause cancer when coated with powder It can obtain a thin and smooth excellent coating surface Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
