Current Status of my country's Powder Coating Technology Market

The potential powder consumption of powder coatings applied on MDF wood-based panels and non-metallic substrates can be compared with the powder consumption on metals.
This is an extremely large high-end market that is about to be developed.

1 Powder coil coating has always been a topic of concern in the powder industry.
After the country recently promulgated regulations on the levy of consumption tax on solvent-based coatings, the call for "replace paint with powder" in the color steel plate industry has been increasing.
The paint speed of domestic color steel plates has reached 120m/min, and the current electrostatic powder spraying technology is difficult to meet this requirement.

Foreign RollCoater has innovated to put a large amount of powder into the powder coating room.
Static electricity is loaded through the static electricity generating area to achieve a large amount of coated powder to reach the substrate.
This method can realize industrial production.
However, it is difficult to control the film thickness in the production process, and it is difficult to obtain a thin coating of 30-40μm.

A domestic foreign-funded enterprise has developed a powder coating with a particle size of 12μm (D50), which is coated with a 23μm thick film on galvanized steel.
The flatness is good, and the corrosion resistance has passed the 1000h salt spray test, reaching the country for color steel plates.
For standard indicators, the company has established a high-pressure slit powder spray test line similar to that developed by Firstprecision, with a line speed of 25m/min, which is in the test stage.

2 The technology for producing such fine powder coatings in China has matured.
As long as the research breakthrough is applicable to this kind of fine powder electrostatic coating equipment, this new and high-end application market will immediately see explosive growth.
At present, the objective market demand is forcing the scientific and technological workers in the coating industry to work hard to increase the gold content in various aspects such as theoretical application, process technology research and equipment research and development for this application field, and leap to a new platform.

3 Technical bottleneck

In the more than 10 years of promotion and application of MDF powder coating technology, the technical bottleneck of the coating process has not been broken in time, resulting in a situation of "three ups and three downs".
The application of color steel plate powder coating technology will inevitably encounter similar technical barriers.
The 1-meter-wide color steel plate is measured at a production speed of 100m/min and the thickness of the coating film is 30-40μm.
It is required that 4-5kg of fine powder can be evenly sprayed on the surface of the steel plate within 1 minute, while ensuring the powder on the surface of the steel plate.
The charge is uniform, and the powder coating needs to be fully cured within 5-10 seconds.
This is the technical bottleneck encountered in the application of color steel powder technology.
Only by overcoming it, this application market will be launched.

It is recently reported that colleagues in the industry are planning to adopt the mechanism of "polymer electric dipolarization and electrification" to design and produce a new color steel plate powder coating model.
This model is a combination of increasing the amount of powder mist spraying and powder charging to solve these difficulties in painting.
Regardless of the success or failure of this research? This is the only way for my country's powder coating technology to move towards high-end.
In order to realize the Chinese dream of powder coatings, scientific and technological workers in our country must take this step firmly and dare to develop new and high-end technology markets.
It not only gives us pressure, but also gives us the impetus for innovation and development.

3 Other powder coating technology markets

The above are two new and high-end large markets.
Their successful application and promotion will undoubtedly greatly promote the development and promotion of powder coatings in my country.
In addition, the range of powder coating technology applications is extremely wide.
The development and application of many new industries will not only increase the use of powder coatings, but also increase the gold content of powder coating technology in many ways.
For example, metal bonding powder coatings, antistatic powder coatings, conductive powder coatings, high temperature resistant powder coatings, antibacterial powder coatings, anion powder coatings, high-reflectivity powder coatings, reflective and heat-insulating powder coatings, heat-dissipating powder coatings, etc.
Their development and application have not only expanded the application range of powder coatings to serve the society.
At the same time, many high-tech and high-level powder coating varieties will be enriched for my country's powder coating library.
Comprehensively improve the technological level of my country's powder coatings.
