The following preparations need to be made before electrostatic powder spraying. 1. Add the specified brand of powder coating (after sieving by the powder sifter) to the powder supply pail according to the specified requirements 1.1 Check and unclog each powder supply line and gun before work, check the gun, be sure to pay attention to whether the gun power and nozzle contact is good, grounding wire is good. 1.2
Why Particle Size Testing is Needed for Electrostatic Spray Powder Coatings Specific effects of particle size distribution on the performance of electrostatic spraying powder coatings. 1. Appearance, leveling Generally speaking, the smaller the particle size of the powder, the better the leveling of the coating curing, the appearance of the coating film will be more flat and smooth, but the powder charged with th
A, the principle of spraying recovery device Electrostatic powder spraying recovery device from the environmental protection equipment in the dust removal device, its basic function is to achieve the two-phase separation of gas and solid mixed fluid, the difference is that the solid phase of the dust removal for waste, while the recovery of the solid phase is the use of materials, with a variety of structures of filter bags, cartridge separator as the main filtering equipment, the princ
1, high-voltage electrostatic generator must be grounded wire. High-voltage electrostatic generator ground wire is the basic safety operation, electrostatic spray gun ground wire is also taken from the high-voltage electrostatic generator, so it should be confirmed that the ground is actually grounded. 2, the object to be coated to maintain a grounded state. The painted object is generally grounded by the conveyor, but the contact part of the spreader, if there is paint attached, will make
Notes on the use of electrostatic spraying equipment In the use of electrostatic spraying equipment often happens some big or small accidents, how to avoid this aspect of the accident? First, most of them are caused by the failure of grounding and forming an insulated state. The conductive objects in the coating room must be clearly distinguished from high voltage potential or grounding potential, except for those who should apply hi
(1) The utilization rate of coating is greatly improved In general, the utilization rate of paint in air spraying is only 30% to 50%, and for porous or mesh structure workpiece, the utilization rate of paint is less than 30%. The use of electrostatic spraying, paint particles by the force of the electric field is adsorbed on the appearance of the workpiece, obviously reduce the splash and rebound, paint loss is greatly reduced, the utilization rate increased by 1 to
In 1962, the French Sames Company successfully researched powder electrostatic spraying equipment, which laid the foundation for the rapid development of powder coating technology. Powder electrostatic spraying method is the most widely used process in electrostatic coating construction. The electrostatic spray gun adsorbs the powder on the surface of the object to be coated by the electrostatic Coulomb force. The most important feature of powder electrostatic spraying technology is that the wor
The significant difference between powder coatings and solvent-based coatings is the different dispersion media. In solvent-based coatings, organic solvents are used as the dispersion medium; in powder coatings, purified compressed air is used as the dispersion medium. Powder coatings are dispersed when sprayed, and the granularity of the coating cannot be adjusted. Therefore, the fineness of the powder particles suitable for electrostatic spraying is important. For powder electrostatic sprayi
Electrostatic powder coating before the need to do the preparation work The following preparations need to be made before electrostatic powder spraying. 1. Add the specified brand of powder coating (after sieving by the powder sifter) to the powder supply pail according to the specified requirements 1.1 Check and unclog each powder supply line and gun before work, check the gun, be sure to pay attention to whether the gun power and nozz
