The color aluminum plate has rich colors, good gloss and smoothness, and the coating can protect against corrosive gases and microorganisms. It is widely used in the construction industry and food packaging industry. Today, the editor of Huaguan Board Industry introduces the common quality problems of color aluminum panels:
1. Color difference There is a color difference phenomenon in the same batch of color coating.
2. Loopholes After the color-coated roll is opened, some sesame grain-sized galvanized surfaces appear on the front or back. Such problems often occur.
3. Paint stripping After the color aluminum plate is opened, the paint will come off after a little rubbing. Shows that the paint is more tender after baking. Or the paint quality is not good and the adhesion is poor.
4. Wrong edge Wrong edge means uneven curling. This type of problem mainly occurs on the color coating of Indian substrates. It is mainly determined by the Indian galvanized sheet production process. This kind of color aluminum plate is used to produce corrugated board without problems. When used in the production of sandwich board, if the rolling speed is high or the technology is not good, it will run off.
5. Scorching Paint baking time is too long, the color turns yellow; or the ambient temperature changes and the machine speed is not adjusted.
The above are several common production defects of color aluminum plates. When buying such products, you can focus on checking whether the products you choose have such defects. Huaguan Board strictly controls quality standards, and products with the above-mentioned problems will not be put into storage
