What’s the Difference between Plastic Spray and Baking Paint Processing?
Generally speaking, the gloss of baking paint processing is better than that of spray coating processing and the advantages in various aspects are also obvious. For example, because the thickness of spray coating processing is thicker than that of baking coating processing, the adhesion and corrosion resistance of spray coating processing are both better than baking paint. Another advantage is that the spray coating process does not require a primer, so its surface treatment is very simple. The process is less complicated. Let's take a look at the differences between them.
1. Difference in processing principles
Plastic spraying is a surface treatment method that sprays plastic powder on the product. It is a simple and very popular metal surface treatment technology; while baking paint processing is to polish industrial paint to the metal surface layer by layer. The steps of this processing technology are very complicated, but also need high-temperature baking and shaping. The process requirements are very high, so modern plastic spray processing is more common.
2. Differences in appearance
In terms of appearance, their advantages are different. The advantage of spray processing is that the coating film has high hardness, so the adhesion is better. However, the appearance of baking paint is brighter, so it will be more beautiful. If you do not know which processing method to use, here is a suggestion. The appearance is generally required to be processed with baking paint. If you are afraid of the coating is not durable, you can use spray processing.
3. Differences in advantages
The spraying process does not require diluting materials. The construction does not pollute the environment and is harmless to the human body. The coating has excellent appearance quality, strong adhesion and mechanical strength, short curing time during spray processing, high corrosion resistance and wear resistance and does not require a primer. In some construction sites, it has been clearly stated that the electrostatic spraying process must be used to handle the electrostatic spraying powder.
The baking varnish is non-stick, the coating film is not easy to adhere to other substances. The thin coating film also shows good non-stick performance. In addition, the baking varnish has heat resistance and moisture resistance. It has excellent wear resistance under high loads. Under certain load, it has the dual advantages of wear resistance and non-adhesion. Baking paint processing is not easily corroded by drugs and can protect parts from any chemical corrosion.
4. Difference in pre-processing
The pre-treatment of plastic spray processing only needs to remove rust, which is very simple and fast. Because the corrosion resistance and adhesion of baking paint processing are not as good as those of plastic spray processing, its pre-treatment needs to be added with pickling phosphating treatment.
5. Surface gloss test
Regardless of whether it is plastic spray processing or baking paint processing, the surface gloss of the measured material during and after processing. Generally, the Linshang gloss metre LS191 is used. The Linshang gloss metre LS191 uses a universal 60 °, which is not only compact, but also highly accurate. It is a very stable instrument. And it is produced in accordance with the national inspection regulations (JJG 696).
6. How to use the gloss metre LS191
First press the button to turn on the instrument and enter the test interface after the calibration is completed. The display interface can display the real-time value, maximum value, minimum value, average value, mean square error value, current recorded value, measurement times and statistical times. After the test is completed, close the instrument to the base of the standard board and it will automatically shut down in 15 seconds.
There is no need to press the button when using Linshang gloss metre LS191. As long as the instrument is placed on the material, the test data is displayed immediately. Press the power button to record the current test data and automatically calculate the maximum, minimum, average and mean square error. The smaller the mean square error value, the more uniform the gloss of the surface of the material.
The gloss metre LS191 can be used not only in the baking paint industry, but also widely used to measure the surface gloss of materials in many industries such as inks, plastics, paper, ceramic tiles, stone, car maintenance, molding molds, metal coatings and other industries.
