How do Surfactants Affect Powder Agglomeration?
Surfactants significantly affect the agglomeration behavior of powder. They change the interfacial properties, force balance, and medium environment of powder particles. The specific mechanism can be divided into five aspects: Adsorption Modification and Surface Energy Reduction Surfactants adsorb onto powder surfaces. This lowers surface energy and suppresses powder agglomeration. The mechanisms include: Hydrophobic Group Anchoring: […]
High Whiteness Negative Ion Powder Preparation Technology
Tourmaline is a silicate mineral with a complex ring structure made of sodium, magnesium, iron, aluminum, and lithium, and is characterized by boron. It has good thermoelectric and piezoelectric effects. It also releases negative ions, radiates far infrared rays, and possesses antibacterial and deodorizing functions. These properties are beneficial to both humans and the environment. […]
How to Choose the Right Quartz Sand for Different 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 […]
Preparation of Silicon-carbon Negative Electrode Materials by CVD Method
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 […]
Ultrafine Powder Characterization, Which Methods are Most Commonly Used?
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 […]

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 […]
Application of Seaweed Powder in Feed
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 […]
How to Minimize Energy Use in Jet Mill Operations ？
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 […]
