With the development of powder coatings, the market demand has increased, and the quality of powder coatings has begun to be uneven. So how do we tell the difference between powder coatings?

First, the appearance identification method:

1, feel

The good powder hand feels silky smooth, loose and floating. The bad powder feels rough, heavy, and heavy. Grab a handful of powder in the hand, the smoother and looser the powder, the better the quality. Conversely, the rough powder feels heavy and the quality is poor. Poor quality powder is not easy to spray, and there are many secondary powders and a large waste.

2, volume

The larger the volume, the less filler in the powder spray coating, the higher the cost, and the better the powder quality. The smaller the volume, the higher the filler in the powder spray coating, the lower the cost and the worse the powder quality. The same weight, large volume is good powder, small volume is the difference powder. The powder is not easy to spray, the second powder is more, the waste is large, the coating area is small, and the use cost is high.

3, storage time

A good powder can be stored for a long time, the powder leveling and other effects remain unchanged. Poor powders can not be stored for a long time, and poor powders deteriorate after 3 months and other effects deteriorate. The normal powder has a shelf life of 12 months at room temperature, and the low-end raw material product is unstable in quality and easy to deteriorate. The powder is produced using poor raw materials, and the sprayed surface accelerates powdering and aging after half a year. In addition, the poor powder is not easy to store, resulting in a large waste of powder and a large fee.

Second, the spray personnel operation identification method: the powder rate

The powder with good powder rate is very easy to spray. It can cover the substrate with 1-3 shots, and the secondary powder is less and the efficiency is high. Poor powder is not good for powder. It can cover the substrate with 3-5 shots. The secondary powder is more recycled and the efficiency is low. The operator can spray the powder rate, and the amount of powder dropped is not much. At the same time, the output of the product is small, and the secondary recycling powder is large, which increases the burden on the operator and is inefficient.

Third, baking recognition method: there is no smoke

Good powder does not produce a lot of smoke during the baking process. Poor powders produce a large amount of smoke during the baking process.

Fourth, the finished product appearance and gloss recognition after baking: the appearance after baking

After the good powder is baked, the appearance of the product is fine, full, transparent and strong, and it can maintain relative luster for a long time. After the poor powder baking, the appearance of the product is dim, dull, the surface is foggy, impervious, and the stereoscopic effect is poor. The gloss is good when it is baked, but it can not maintain the long-term luster stability. , powdering, stripping and other phenomena.

5. Adhesion and aging identification method: adhesion and aging

Good powder has strong adhesion, strong toughness, and can be kept from powdering and aging for several years. Poor powder adhesion is poor, very brittle, aging and powdering after three months to six months after spraying. The adhesion and bending were tested in comparison, and the product was aged or pulverized after several months of observation. Adhesion and aging are poor, the product is easy to age, powder, rust, and shorten the service life of the product.

Seven, high temperature identification method: high temperature

Adjust the temperature to 220-230 degrees, keep warm for 10-15 minutes, good powder, temperature and weather resistance is better, after high temperature baking, the color change is small, the gloss changes little. Poor powder, temperature and weather resistance is relatively poor, after high temperature baking, the color is severe, and the gloss becomes dumb. This method is particularly effective for detecting outdoor light-colored powders. Poor powders use poor resin, titanium dioxide, poor pigments and fillers, temperature and weather resistance. Low cost, shoddy.

Eight, environmental identification method: SGS environmental testing

Good powder materials are produced by large factories, and environmental protection is guaranteed. Poor materials and recycled powders cannot guarantee long-term environmental protection. Environmental protection SGS testing environmental protection exceeds the standard will give some export enterprises a big trouble to build a car.

Analysis of the current status of powder coatings:

Powder coatings are processing consumables products, the investment threshold is relatively low, and the market competition is fierce. It also causes the powder coating coating market to be in chaos, and the phenomenon of cutting corners is serious, which has caused a relatively large impact on some genuine enterprises, plus powder coating For powdery substances, it is not easy to identify, giving some large economic losses caused by powder enterprises. The actual amount of the original product is 3 tons. The material is adulterated and cheaper. The powder dosage is increased to 4-5 tons, which increases the cost of the powder enterprise. Most of the powder enterprises only care about the powder and do not care about the actual use cost. , causing greater losses to the enterprise.
