How to prevent the powder coating used in cabinets from agglomeration and uneven particle size during cooling and grinding? Are effective cooling and grinding equipment used?

During the manufacturing process, powder coatings need to be quickly cooled after melting, extrusion, and solidification to prevent adhesion and agglomeration caused by high temperature. In our production process, we pay special attention to the design and optimization of the cooling link, which is specifically reflected in the following aspects:
Fast cooling system: We use advanced fast cooling technology, using efficient cooling fans and precise temperature control systems to ensure that the extruded coating is quickly cooled to a safe range. This system can accurately adjust the wind speed and temperature, which not only ensures the rapid cooling of the coating, but also avoids stress cracking caused by rapid temperature changes.
Segmented cooling strategy: In order to further optimize the cooling effect, we implemented a segmented cooling strategy. That is, according to the characteristics of the coating and the actual situation of the production line, the cooling area is divided into multiple stages, and different cooling rates and temperatures are set for each stage to achieve more uniform and efficient cooling.
Intelligent monitoring system: In combination with the Internet of Things technology, we installed an intelligent monitoring system to monitor the temperature, humidity and coating status during the cooling process in real time. Once an abnormality is found, an alarm will be issued immediately and the cooling parameters will be automatically adjusted, effectively preventing the problem of coating agglomeration caused by human operation errors or environmental factors.
Grinding is another key link in the production of cupboard powder coatings, which is directly related to the particle size distribution and uniformity of the coating. Our advantages in this regard are mainly reflected in:
Advanced grinding equipment: The company has introduced the German ZEPPELIN bonding machine and supporting precision grinding equipment. These equipment use advanced grinding principles and automatic control systems to accurately control the grinding time and force to ensure that the coating particles are uniform in size and avoid the problem of poor spraying effect caused by uneven particle size. With its efficient and stable performance, the ZEPPELIN bonding machine effectively reduces the heat accumulation of the coating during the grinding process and further reduces the risk of agglomeration.
Grading screening system: The ground coating needs to be strictly screened to ensure that the particle size meets the product standards. We use a multi-stage screening system to subdivide the coating through screens with different apertures, which not only removes oversized or undersized particles, but also achieves further optimization of particle size distribution. This system is equipped with an automatic screen cleaning device to effectively prevent the screen from clogging and ensure the screening efficiency and accuracy.
Airflow dispersion technology: In the paint processing after grinding and screening, we innovatively introduced airflow dispersion technology. By precisely controlling the speed and direction of the airflow, the paint particles are evenly dispersed in the airflow, effectively avoiding the agglomeration between particles, and further improving the dispersion and fluidity of the paint, which is essential for the uniform spraying of complex surfaces such as cabinets.
Combining the above technologies and equipment, our company has shown significant advantages in the cooling and grinding process of powder coatings:
Perfect R&D system: Having our own raw material production center and powder coating R&D center enables us to control the quality of raw materials from the source, continuously optimize the formula and production process, and ensure the excellent performance of the coating.
Advanced testing equipment: SHIMADZU XRF is used for elemental analysis, Mastersizer 3000E is used for particle size distribution testing, and Datacolor 400 is responsible for color matching and quality control. These high-precision testing equipment provides us with strong technical support to ensure that each batch of products meets international standards.
Strict quality management: Establish a complete quality assurance system and implement ISO quality management system standards. From raw material procurement, production and processing to finished product inspection, each link strictly follows the established process to ensure stable and reliable product quality.
Global market recognition: Our products are not only well-known in the domestic market, but also exported to Europe, the United States, Southeast Asia, South America and other places, winning the trust and praise of global customers.
