Glass powder 400 mesh refers to glass powder whose particle size meets the 400 mesh standard after screening, usually with a particle diameter of 30-40 microns. Compared with glass powders of other particle sizes, 400 mesh glass powder has finer particles and higher specific surface area, so it has better fluidity, dispersibility and reactivity. This makes it show strong performance advantages in some industries with high fine requirements, such as building materials, coatings, rubber and other fields.
Compared with coarser glass powders (such as 100 mesh and 200 mesh), 400 mesh glass powder has smaller particles and smoother surface, which enables it to be more evenly distributed in the mixture and improve the quality of the final product. Although coarse-grained glass powder has lower production costs, it is difficult to disperse evenly due to its large particles, and is often used in some occasions where particle size requirements are not high.
In addition, 400 mesh glass powder is often used to improve the density, compressive strength, wear resistance and other properties of materials such as concrete and coatings, while coarse-grained glass powder is mainly used for products with lower particle requirements, such as building road repair and brick production.
Difference from other particle size glass powders
Particle size difference:
Compared with coarser glass powders (such as 100 mesh or 200 mesh), 400 mesh glass powder has finer particles, smoother surface and larger specific surface area. Therefore, it has more advantages in many delicate industrial applications, especially in occasions requiring uniform distribution and higher reactivity. In contrast, coarser glass powder has large particles and small surface area, and is usually used in some occasions where particle size requirements are not strict.
Applicability:
The particle size of glass powder directly affects its application in different fields. 400 mesh glass powder is widely used in building materials, coatings, rubber, plastics, fertilizers and other industries. In building materials, 400 mesh glass powder can effectively improve the density and compressive strength of concrete; in the coating industry, its fine particles help improve the adhesion and gloss of the coating. Coarser glass powder (such as 100 mesh or 200 mesh) is more used in rougher products, such as road repair or brick production.
Performance Difference
Fine-grained glass powder (such as 400 mesh) generally has better fluidity, dispersibility and reactivity. Because of its smaller particles, it has a higher surface area and can be more evenly distributed in the mixture, improving the uniformity and performance of the material. For example, adding 400 mesh glass powder to concrete can improve its compressive strength, wear resistance and chemical resistance. Coarser glass powder may be difficult to mix evenly with other ingredients due to its large particles, affecting the performance of the final product.
Cost Difference:
The process of producing finer glass powder (such as 400 mesh) is more complicated, so the production cost is also higher. In contrast, coarser glass powder has a lower production cost and is suitable for cost-sensitive applications. When choosing the particle size of glass powder, enterprises often need to make a trade-off based on budget and application requirements.
In general, glass powder 400 mesh has irreplaceable advantages in many fields due to its fine particles and excellent performance. Choosing glass powder with the right particle size is crucial to improving product quality and performance.
