How Manufacturers Judge Electrostatic Powder Quality
Currently, most enamel manufacturers of household appliances such as water heaters, microwave ovens, washing machines, enamel cookware, and architecture panels adopt dry electrostatic powder coating. The selection of electrostatic powder directly affects the quality and production efficiency of products. Therefore, The enamel manufacturers must comprehensively consider various performance indicators when purchasing electrostatic powder. It requires manufacturers not only to focus on the basic performance of the powder but also to deeply understand how these performances play a role in actual production.
Firstly, the migration quantity (amount of powder applied, amount of powder applied per unit time) is an important indicator for evaluating the powder's adhesion effect. It refers to the weight of powder on a 10mm*10mm standard plate after a fixed electrostatic spraying time (e.g., 20s). Through standard plate testing, the powder's adhesion ability within a unit time can be directly understood. The larger the value, the better the powder's adhesion effect, which can significantly improve production efficiency.
Secondly, the fluidity is an essential performance indicator before electrostatic powder spraying. Good fluidity ensures that the powder is fully dispersed during the fluidization process, guaranteeing continuous and uniform powder supply to the spray gun during spraying. This not only helps improve spraying effects but also reduces waste during the spraying process.
Thirdly, the powder adhesion is a key factor in evaluating powder quality. Through impact test of specialized equipment, the powder's adhesion stability on the plate can be understood. High-adhesion powder ensures that products do not easily fall off during long-term use, thereby enhancing product durability and aesthetics.
In addition to the above key parameters, indicators such as density, acid resistance, particle size, and moisture content are also factors to be considered when purchasing electrostatic powder. These indicators jointly determine the powder's comprehensive performance and usage effects.
