Le rôle clé du broyeur à classification pneumatique dans le traitement des poudres protéiques
The global food supply chain is undergoing significant changes, driven by rising population and increasing demand for sustainable protein sources. Traditional livestock farming, which requires vast amounts of land and water, can no longer meet this demand alone. As a result, alternative protein sources—such as plant-based, mushroom, insect, algae, and bacterial fermentation biomass—are becoming crucial […]
Diversified Applications of Dolomite Powder: Exploring Its Unique Value in Various Industries
Dolomite is a carbonate mineral, which includes iron dolomite and manganese dolomite. Its crystal structure resembles that of calcite and is commonly found in rhombohedral form. When it comes into contact with cold dilute hydrochloric acid, it slowly produces bubbles. Some dolomites emit an orange-red glow when exposed to cathode rays. Dolomite is the main […]
Quelles sont les poudres absorbantes couramment utilisées pour les matériaux polymères ?
With the increasing number of electronic devices, invisible electromagnetic waves have become a source of electromagnetic pollution, threatening information security. This is where electromagnetic wave absorbing powders in polymer materials come into play. They absorb and shield electromagnetic waves, enhancing the electromagnetic compatibility of materials and ensuring the stable operation of electronic devices. They can […]
[Vulgarisation scientifique] Caractéristiques et applications de la gomme arabique
Gum arabic (Gum arabi, Acacia senegal, Acacia seyal), also known as Sudan gum, acacia gum, Senegal gum, and Indian gum, is an exudate from the trunks of trees in the genus Acacia of the legume family.

Le charme caché de l'amidon de riz : petites particules, grand potentiel
Among all known grains, rice starch has the smallest particle size, with an average diameter of only 2-8 μm. In comparison, corn starch ranges from 5-25 μm, wheat starch from 2-45 μm, sorghum starch from 5-25 μm, and potato starch from 15-100 μm. The small particle size and high specific surface area of rice starch […]
Let’s Talk About Powder Dispersion
The dispersibility of powder directly affects its stability, flowability, wettability, and uniformity in solvents. Ultimately, it determines the product quality. In other words, the powder dispersion directly impacts the application value of powder materials. Powder Dispersion and Dispersants Due to the large specific surface area and surface energy of ultrafine powders, particles are prone to […]
