The influence of color powder particle size on products is mainly based on the following aspects:

1. Coloring effect and color uniformity

Particle size and dispersibility: The smaller the particle size of the color powder, the larger its specific surface area, making it easier to disperse evenly in the medium, thereby improving the coloring effect and color uniformity. A smaller particle size helps reduce the aggregation between particles, making the color more delicate and uniform

Transparency and coverage: The particle size is closely related to the coverage and transparency of the color powder. Generally speaking, smaller particle size pigments can provide higher coverage while maintaining a certain level of transparency. However, when the particle size decreases to a certain extent, diffraction of light may occur, leading to an increase in transparency and a decrease in coverage. Therefore, customers will choose the appropriate particle size range based on their specific needs

2. Processing performance

Liquidity and Mixing: The particle size of color powder has a significant impact on its fluidity and mixing. A smaller particle size helps to improve the flowability and mixing of color powder during processing, ensuring that the color powder can be uniformly and quickly dispersed in the medium. This is crucial for improving production efficiency and product quality

Equipment adaptability: Different particle sizes of color powder also have different adaptability to processing equipment. When customers choose color powder, they should consider the requirements of their processing equipment for the particle size of the color powder to ensure that the equipment can operate normally and achieve the expected processing effect

3. Product performance

Durability: The particle size of color powder is also related to its durability. A smaller particle size means a larger contact area between the colored powder particles, which helps to enhance the bonding force between particles and improve the durability of the product

Weather resistance: For outdoor products such as coatings, plastics, etc., the weather resistance of color powder is an important indicator. A smaller particle size helps to improve the weather resistance of the color powder, enabling it to resist the erosion of natural factors such as ultraviolet radiation and rainwater

4. Cost and Environmental Protection

Production cost: The particle size of the color powder also affects the production cost. Generally speaking, smaller particle size pigments require finer grinding and dispersion processes, which can increase production costs. Customers will weigh cost and performance and choose the most cost-effective color powder particle size

Environmental requirements: With the increasing awareness of environmental protection, customers have also put forward higher requirements for the environmental friendliness of color powders. A smaller particle size helps reduce dust pollution during the processing and use of color powder, meeting environmental requirements

In summary, the customer's requirement for the size of the color powder particles is based on various considerations such as coloring effect, processing performance, product performance, as well as cost and environmental protection. Therefore, when choosing color powder, customers need to determine the appropriate particle size range based on specific application scenarios and requirements
