Powder coating machine is how to use the process carried out spraying processing spraying machine coating operation market There are many ways, whether it is air spray, airless spray formula is still mixed gas sprayed in the market have been widely used, but Another method that is spraying powder coating, spray coating method that has also been to promote them! To understand the principle of electrostatic spraying, we first of all it is about the principle of corona discharge between the electrodes when the needle with a flat plate applying a DC voltage bridge polyurea spray process, the attack uneven field. Charge density in the top part of the largest, top electronics was announced accelerated and emitted high speed polyurea spray process, so that nearby air ionization, while electronic attack, and then attack other ionization of neutral molecules and attack. Such a chain reaction, can rapidly add a current, and therefore the onset of sparks. Corona discharge process that is using the principles of physics discharge electrodes, that is, using the principle of electrostatic spraying DC corona discharge. When the gun cup to the negative, the workpiece is grounded in high voltage electric field strength of the effect, spray cup marginal workpiece attack corona discharge. When the coating from the spray gun to spray or flow cup thrown when the force was strong electric field ionization effect Qishi polyurea spray processing, paint particles are negatively charged, because of mutual exclusion and ionized into very small particles, until the repulsive force equal to its its surface tension stop. Painting means for metal, plastic, wood and other materials processed into products, which are covered in a protective layer or decorative layer coating the surface. Development of coating technology and equipment experienced by the manual to automatic production line machinery and equipment and then to the development process. Painting equipment industry in the introduction of the true origin of the fifties, when the Soviet technology. Starting from the 1960s, due to the development of light industry, first appeared in the bicycle manufacturing industry automated production lines, the main task of painting industry during this period was mainly to corrosion. But with the rapid economic development of the interior, as well as efficient progress abroad Dasan polyurea coating technology coating process, through the exchange of technology and the introduction of foreign technology, painting technology began rapid development of our country, in terms of painting automated production spraying development and promotion of equipment and technology to promote the application of electrophoretic coating and powder coating technology, the coating equipment has obviously made great progress and development. Polyurea spray sand processing _ _ Dasan Hong Hardware Electric spray polyurea spray process provided by the Dongguan City, Sha Hong Hardware Electric Co.
