Powder coating is the most widely used decorative material, and it appears in every aspect of our lives. So, do you know what kind of powder coating is of good quality?


Appearance recognition method


Hand feel: The powder coating feels silky smooth, fluffy, and floating, rather than rough and heavy. Hold a handful of powder, the smoother the powder will be, the better the quality. On the contrary, the powder will feel rough, heavy, poor quality, and difficult to spray.


Volume: The larger the volume, the less the filler in the powder coating, the higher the cost, and the better the powder quality; the smaller the volume, the higher the filler content in the powder coating, the lower the cost, and the worse the powder quality. The same carton has a large amount of powder and is a high-quality powder. Inferior powders are expensive to use.


Storage time: Good powder can be stored for a long time, and the effect of powder level dyeing remains unchanged. Inferior powder cannot be stored for a long time. Poor powder will have effects such as poor leveling after 3 months. Ordinary powder has a shelf life of 12 months at room temperature, and the quality of products using low-end raw materials is unstable and easily deteriorated. Using low-quality raw materials to produce powder, the spraying surface will accelerate the pulverization and aging after half a year. In addition, the powder is not easy to store, causing a large amount of waste and high cost to customers.


Recognition method of spraying area


The resin content of ordinary powder should be about 55-65%, the resin is about 3.1 US dollars/KG, and the filler is about 0.31 US dollars. Some low-quality powder factories use less than 45% resin content to collect counterfeit products, increase fillers to reduce costs and reduce spraying area.


Comparison method: Two identical powders are sprayed with the same product. If there are fewer powder sprayed products, the use cost is high. For manufacturers, the spraying area is small and the use cost is high. According to the calculation of spraying 6 squares per kilogram, each less sprayed square is equivalent to an extra 0.47-0.94 US dollars per kilogram of powder. Therefore, try to use good quality powder coatings, not only to save costs, but also to increase credibility.


Work efficiency of spraying personnel


Good powder is easy to spray, and the substrate can be covered by spraying 1-3 guns. There is less powder recovery and high work efficiency. Poor powder is not easy to powder, spray 3-5 guns to cover the substrate, too much powder is recycled again, and work efficiency is low. Workers can judge the quality of the powder by the powder spray rate.


Baking identification method


A good powder will not produce a lot of smoke during the baking process. Inferior powder will produce a lot of smoke during the baking process.


Finished product appearance and gloss recognition method


A good powder product has a delicate, plump, transparent and three-dimensional appearance. Inferior powder products have a dim appearance, impervious to water, and poor three-dimensionality. A good powder can maintain relative gloss for a long time. The gloss of the powder is poor, it was okay when it was just out of the oven, and it started to shine after a few shots.


Adhesion aging identification method


Good powder has strong adhesion and toughness, and can be kept for several years without powdering or aging. Inferior powders have poor adhesion and are very brittle. Aging and powdering will begin 3 months to half a year after spraying. Compare and test the adhesion and bending, and observe whether the product is aging or chalking after a few months. Poor adhesion, aging, products are prone to aging, chalking, and rust, which shortens the service life of products and affects customer reputation.


High temperature identification method


Adjust the temperature to 220-230 degrees and keep it for 10-15 minutes. The powder quality is good, the temperature and weather resistance is better, the color change after high temperature baking is less, and the gloss change is small. Inferior powder has poor temperature resistance and weather resistance. Discoloration is serious after high-temperature baking and becomes matte.


Environmental Appraisal Law


Good powder materials ensure environmental protection. However, even if recycled powder is added to inferior materials, there is no guarantee that it will not exceed the standard for a long time.
