Provide the best powder coating system solution
What is the main difference between shot blasting machine and sand blasting machine Shot blasting is the use of high-speed rotation of the impeller to small steel or iron shot thrown out of the high-speed impact on the surface of the parts, so you can remove the oxidation layer on the surface of the parts.…
DetailsThe coating line uses high-pressure electrostatic automatic spraying system, in the actual process of production, we have to constantly figure out the construction characteristics of various colors; for different coatings, you need to choose the right automatic sprayer parameters (paint volume, forming air pressure, voltage value), the impact of the adjustment range on the appearance…
DetailsSpecific effects of particle size distribution on the performance of electrostatic spraying powder coatings. 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 the square of the…
Detailsetails 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…
DetailsWhat standards are needed for electrostatic powder coating The fineness of electrostatic powder particles: The significant difference between powder coatings and solvent-based coatings is that the dispersion medium is different. In solvent-based coatings, the use of organic solvents as a dispersion medium; and in powder coatings, the use of purified compressed air as a dispersion…
DetailsMetal pretreatment cleanliness testing method In simple terms, the role played by metal degreasing is to remove the dirt accumulated on the metal surface during previous operations and to prepare it for subsequent operations. Cleaning metals involves not only the selection of the type of degreasing agent, but also the appropriate degreasing process and process…
DetailsSeveral ways to identify the authenticity of powder coatings There are several ways to identify the authenticity of powder coatings. I. Appearance identification method Hand feeling Hand feeling is silky smooth, loose, floating. Feel rough, sinking hands, feel heavy. Grab a handful of powder in the hand, the more smooth powder pent loose, good quality,…
DetailsReasons and treatment of powder coating powder drop phenomenon after coating The lower the dielectric constant of powder, the easier it is to charge the particles, but the easier it is to lose the charge, which is reflected in the powder adsorption force on the workpiece, and the powder will fall off when it is…
DetailsPowder coating and its construction precautions Powder coating refers to a new type of solvent-free 100% solid powder coating. It is solvent-free, non-polluting, recyclable, environmentally friendly, saves energy and resources, reduces labor intensity and has high mechanical strength of the coating film. Classification Powder coating is a completely different form from the general coating, it…
DetailsThe storage of powder has a great influence on its quality. The storage of powder will generally be in a ventilated and dry place, and the temperature of the storage space should not exceed 30 degrees. Different varieties of powder can not be placed together to avoid mutual pollution. Different manufacturers of powder, in the…
