Surface modification and coating uniformity of calcium carbonate
Due to the strong hydrophilicity of the surface, untreated calcium carbonate easily aggregates into clumps in the coating, causing particles or spots to appear on the surface of the coating, affecting the appearance and functionality. Calcium Carbonate Modification Machine solves this problem through the following technical means:
Application of surface modification technology
The equipment changes the calcium carbonate surface from hydrophilic to lipophilic or hydrophobic through chemical modification, making it easier to integrate with the paint matrix. The surface of the modified calcium carbonate is evenly covered with a layer of organic molecules, which not only enhances the compatibility with the organic components in the coating, but also reduces the mutual attraction between particles, thereby significantly improving the dispersion performance.
Supported by efficient drying technology
The high-efficiency drying system equipped with the equipment completely removes moisture from calcium carbonate through precise temperature and humidity control, further improving the fluidity and dispersion of the powder.
The dried calcium carbonate can be more evenly distributed in the paint, ensuring that the paint is evenly applied during the construction process and reducing the occurrence of surface defects.
Specific effects of improved smoothness and uniformity
Reduce coating defects
The uniform dispersion of modified calcium carbonate can effectively reduce defects such as brush marks, bubbles and surface particles caused by particle aggregation in the paint.
The coating surface is smoother, feels delicate, and the optical effect is significantly improved, helping to enhance the visual appeal of the product.
Improve covering power
Highly dispersible calcium carbonate can enhance the hiding ability of coatings, allowing the coating to effectively cover underlying defects.
This effect is particularly suitable for architectural and decorative coatings that require smooth surfaces.
Enhanced durability
A smooth and even coating surface makes it harder for dust and dirt to accumulate, making it easier to clean. It also effectively reduces the risk of the coating peeling or cracking, extending the service life of the coating.
