How to Choose Fine Attapulgite Powder?

Particle size is a critical factor in the performance and functionality of rheology modifiers used in various industries. In the realm of paints, coatings, and construction materials, sepiolite and attapulgite clays have emerged as effective rheology modifiers, thanks to their unique thixotropic characteristics. Understanding the significance of particle sizes in sepiolite and attapulgite clays and their impact on material properties is key to optimizing formulation outcomes.

One common misconception in the industry is the confusion between fiber length and particle size. All sepiolite and attapulgite clays based on short fibers, should be below 5 μm, this classification would place them in Group 3, meaning the agent is not classifiable as carcinogenic to humans, as defined by the International Agency for Research on Cancer (IARC) and the World Health Organization (WHO).

When we refer to fibers, we specifically mean independent and interlocking fibers. On the other hand, particles are formed by bundles of these fibers, which can be separated or broken again. It's essential to differentiate between these terms when discussing particle sizes and/or fiber lenght sizes.

Paints and coatings industries generally require particle sizes below 15-20 microns for optimal performance. On the other hand, construction materials industry may tolerate higher particle sizes and for example, joint compounds industries are not typically concerned with particle sizes of 40-45 microns.

While there is no fixed law dictating particle sizes and their applications, it is crucial for the materials to always offer good dispersion properties.

In formulation development, understanding the relationship between particle size and desired material properties is essential. Smaller particle sizes generally contribute to improved dispersion, stability, and effectiveness as rheology modifiers (as we see commonly in Paints & Coatings Industry). The fine particle sizes of sepiolite and attapulgite clays allow for better interaction with the surrounding medium, resulting in enhanced thickening, suspension, and stability characteristics.

Additionally, the particle size distribution should be carefully considered to achieve optimal performance. A well-controlled particle size distribution ensures consistent and reproducible results across different batches and formulations.

Formulators and researchers must also be mindful of the specific application requirements when selecting particle sizes for sepiolite and attapulgite clay rheology modifiers. Each industry and product have unique demands, and finding the right balance between particle size, functionality, and cost-effectiveness is crucial.

In conclusion, particle size is a vital parameter in the design and development of rheology modifiers, particularly sepiolite and attapulgite clays used in paints, coatings, and construction materials. Understanding the distinctions between fiber length and particle size, along with the targeted application requirements, allows formulators to optimize material properties and achieve desired performance outcomes. By leveraging the precise and fine particle sizes of sepiolite and attapulgite clays, formulators can unlock the full potential of these unique rheology modifiers in their formulations.

Magnesium (Mg) Metal

Magnesium (Mg) is a light, moderately hard, silvery-white metal that ignites easily in the air and burns with a bright light. It is strong, has good heat dissipation and dampening, and is easy to weld, forge, cast or machine. It can improve the mechanical, fabrication, and welding characteristics when used as an alloying agent since it has a low density and is the lightest structural metal (a third lighter than aluminum). It also has good electrical properties. Magnesium turnings and chips are produced by milling commercial and high-purity magnesium, keeping size under control to obtain the desired specific surface and reactivity. They are silver-white. initially, but can turn to a dark gray if stored improperly. Purity: Standard purity (99.8% Mg) Ultra-high purity (99.98% Mg)
