Comment choisir le sable de quartz adapté aux différentes industries ?
Quartz sand is an important basic non-metallic mineral resource, widely used in fields such as glass manufacturing, mechanical casting, electronics, metallurgy, refractory materials, chemicals, and ceramics. Customers often ask which products their quartz ore is suitable for and which industries it can be applied to. Based on the silica (SiO2) content, a preliminary judgment can […]
Préparation de matériaux d'électrode négative silicium-carbone par la méthode CVD
Common methods for preparing silicon-carbon negative electrode materials include mechanical ball mill, spray drying, chemical vapor deposition (CVD), etc. Mechanical ball mill crushes bulk materials into fine particles by colliding with rotating balls. The process is simple and the cost is low, but the particle agglomeration phenomenon is serious. In addition, excessive grinding will destroy […]
Caractérisation des poudres ultrafines : quelles sont les méthodes les plus couramment utilisées ?
Ultrafine powder (also known as ultrafine powder) usually refers to powder with a particle size below 1250 mesh (10μm). It is subdivided into micron powder, submicron powder and nano powder. When solid matter is crushed to micron or even nanometer scale, its physical and chemical properties will change significantly. This makes ultrafine powder a hot […]
Poudre de talc dans la modification des plastiques
In today’s plastics industry, modified plastics have attracted much attention for their excellent performance and wide application fields. Talcum powder, as an important and widely used inorganic mineral filler, plays a vital role in plastic modification. Talcum Powder can not only effectively improve the physical properties of plastic products, but also reduce their production costs […]
La technologie de traitement des poudres repousse les limites de la performance robotique
In modern manufacturing, the importance of powder materials is becoming increasingly prominent. Especially in the field of robot manufacturing, powder materials account for more than 65% of the weight of the robot, such as metal powder, ceramic powder and composite powder. With the continuous advancement of technology, the precision of powder processing has also achieved […]
Quels indicateurs sont nécessaires pour produire du carbonate de calcium de haute qualité à partir de calcite ?
Calcite is a natural calcium carbonate mineral and the primary raw material for ground calcium carbonate (GCC). The grade and impurity content of calcite ore directly impact the quality of the final product. High-end calcium carbonate from calcite requires high-purity ore with low levels of heavy metals and other impurities. These factors determine whether the […]
Utilisation de la poudre d'algues dans l'alimentation animale
There are more than 10,000 species of marine algae, classified into 10 phyla. They can be divided into green, brown, blue, yellow, and golden algae based on pigment content. Based on morphology, they are classified into macroalgae and microalgae. Macroalgae include kelp, kombu, and giant kelp from brown algae. They also include Cladophora and Codium […]
Comment minimiser la consommation d'énergie dans le fonctionnement des broyeurs à réaction ?
Jet mills are known for their ability to grind materials without producing contamination. After grinding, the high-speed compressed airflow slows down and increases in volume. This process absorbs heat and has a cooling effect on the material, making it ideal for ultrafine grinding. In jet mill operations, high-speed airflow accelerates particles to collide with each […]
Comment choisir le bon dispersant pour éviter l'agglomération des poudres ultrafines ?
Choosing the appropriate dispersant to prevent the ultrafine powder agglomeration requires a comprehensive consideration of powder properties, dispersing medium, and processing conditions. The following are key principles and strategies: Select the Dispersant Type According to The Powder Characteristics Surface Charge and Polarity Matching Polar powders (such as ceramics, oxides): Prefer anionic dispersants (e.g., sodium polyacrylate, […]
