Vietnam Customer Visits Daswell Powder Tech. for GCC Powder Coating Test with Excellent Results
On March 19, 2026, a customer from Vietnam visited Daswell Powder Tech. to carry out a coating test using their own ground calcium carbonate material at our factory.
The visit aimed to evaluate the coating performance of our powder surface treatment equipment before making a purchasing decision.
Customer Material and Application Requirements
The customer brought GCC powder with the following specifications:
These applications require coated powder with:
Coating Test with Turbo Coating Machine
The test was carried out using our turbo coating machine. This machine is designed for efficient surface treatment of mineral powders.
With high-speed vortex mixing, the turbo coating machine ensures:
Uniform distribution of coating agent
The turbo coating machine utilizes high-speed vortex airflow and intensive mixing to ensure that the coating agent (such as stearic acid) is evenly distributed on the surface of each particle.
This uniform coating significantly improves powder consistency and ensures stable performance in downstream applications such as plastics and non-woven materials.
Efficient particle surface treatment
Through strong mechanical and thermal interaction inside the chamber, the coating agent is effectively bonded to the particle surface.
This results in a high coating efficiency and activation rate, enhancing powder properties such as dispersion, hydrophobicity, and compatibility with polymer matrices.
Efficient particle surface modification
Designed for industrial production, the turbo coating machine operates in a continuous mode with stable material flow and consistent output.
Its robust structure and optimized internal design reduce fluctuations in product quality and ensure reliable long-term operation.
Flexible Process Control
The system allows precise adjustment of key operating parameters to match different materials and application requirements, including:
coating agent dosage, feeding rate, temperature control, cotor speed, and airflow conditions.
Coating Result
After several rounds of adjustment and optimization, the final coated GCC powder showed:
For plastic and non-woven production, these improvements are critical for maintaining stable product quality, efficient processing, and reliable performance.
Customer Feedback
The customer expressed strong satisfaction with the test results and recognized the performance advantages of Daswell Powder’s turbo coating machine. The successful trial has increased the customer’s confidence in our equipment and laid a solid foundation for further cooperation.
