Coating technology: powder electrostatic spraying technology

Core tip: the so-called powder electrostatic spraying is to use the principle of high-voltage electrostatic corona field A high voltage negative electrode is connected to the metal guide sign at the head of the spray gun, and the sprayed workpiece is grounded to form a positive electrode, so as to form a strong electrostatic field between the spray gun and the workpiece When the powder coating is sent from the powder supply barrel to the guide rod of the spray gun by the compressed air as the carrier gas, because the guide rod is connected with the corona discharge generated by the high-voltage negative pole, a dense negative charge is generated near the guide rod, which causes the powder to carry the negative charge and enter the electrostatic field with high electric field strength Under the double action of electrostatic power and carrier gas, the powder Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: the so-called powder electrostatic spraying is to use the principle of high-voltage electrostatic corona electric field A high voltage negative electrode is connected to the metal guide sign at the head of the spray gun, and the sprayed workpiece is grounded to form a positive electrode, so as to form a strong electrostatic field between the spray gun and the workpiece When the powder coating is sent from the powder supply barrel to the guide rod of the spray gun by the compressed air as the carrier gas, because the guide rod is connected with the corona discharge generated by the high-voltage negative pole, a dense negative charge is generated near the guide rod, which causes the powder to carry the negative charge and enter the electrostatic field with high electric field strength Under the double action of electrostatic power and carrier gas, the powder flies to the ground evenly A thick and even powder layer is formed on the surface of the workpiece, and then heated and solidified to form a durable coating The following is the construction process and requirements of electrostatic powder spraying 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,
