飼料への海藻粉末の応用
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 from green algae, and nori and Corallina from red algae. Microalgae are the smallest, single-celled algae, with diameters only a few micrometers, but are abundant. Algae can be processed into seaweed powder. The use of seaweed powder in feed provides essential trace minerals, amino acids, and vitamins that support optimal growth in animals. Currently, the […]
ジェットミル操業におけるエネルギー消費を最小限に抑えるには？
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 other or target surfaces to achieve the grinding effect. These mills are often preferred in applications where maintaining material purity is critical. This includes the production of pharmaceuticals, food additives, and high-performance coatings. Key Methods to Accelerate Particle Grinding with High-Speed Airflow In jet mill operations, there are three primary methods used to accelerate solid […]
超微粒子の凝集を防ぐための適切な分散剤の選び方とは？
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, sodium hexametaphosphate) to prevent the ultrafine powder agglomeration through electrostatic repulsion. For example, ZnO is stably dispersed at pH = 5 via double-layer repulsion.Non-polar powders (such as graphene, carbon black): Use non-ionic dispersants (e.g., PVP, PEG) to prevent contact through steric hindrance. For high surface energy materials (e.g., nano-silicon carbide), combine in-situ functionalization (e.g., silane […]
ステアリン酸表面改質炭酸カルシウムはどのように製造されるのですか？
Stearic Acid Surface Modified Calcium Carbonate is widely used in various industries, especially plastics, rubber, coatings, and adhesives. Its primary role is to enhance the dispersion and compatibility of calcium carbonate in composite materials, thereby improving performance. The stearic acid molecule has both hydrophilic and hydrophobic segments. The hydrophilic group interacts physically and chemically with the calcium carbonate surface. Through adsorption and coating, it effectively reduces particle interactions, leading to more uniform dispersion in polymer matrices. Stearic acid surface modified calcium carbonate can be processed using either dry or wet methods. The wet method typically requires the use of stearic acid salts, such as sodium stearate. Both methods have their […]
多孔質炭酸カルシウムとは何か、そしてその用途は？
Porous calcium carbonate (CaCO3) particles are gaining attention for use in chromatography, biomolecule loading, and pharmaceuticals release. They are also applied in biomimetic minerals and superhydrophobic surface construction. Preparation Technology of Porous Calcium Carbonate The template method has become the main approach for preparing porous calcium carbonate.Surfactants, polymers, and natural plant components are used as templates. With research progress, methods like co-precipitation, emulsion membrane, and solvent/hydrothermal methods have been developed. These methods greatly enrich the preparation techniques. Among various preparation techniques, the template method is commonly used and well-established. The main principle is to coat the chosen template with calcium carbonate, forming a core-shell structure. The template is then removed […]
改質ウォラストナイト：高価値かつ高効率
Wollastonite is a fibrous silicate mineral with a needle-like structure and high whiteness. It has a low coefficient of thermal expansion, excellent chemical stability, and flame-retardant properties. It also has high electrical insulation, making it suitable for various applications. However, natural wollastonite is hydrophilic. To enhance resource utilization and add value, modified wollastonite is necessary. The Significance of Modified Wollastonite Powder Wollastonite, especially ultrafine high aspect ratio wollastonite, is widely used in plastics, rubber, and fibers. It is also used as a filler and pigment in coatings, adhesives, and composite materials. As an inorganic material, wollastonite lowers cost and enhances stability, rigidity, flame resistance, and insulation. However, its poor compatibility […]

石灰石の主な用途は何ですか？
Limestone, also known as “Qing Stone” or “Gray Rock,” is a mineral aggregate primarily composed of calcite. It often contains dolomite, magnesite, and other carbonate minerals. The chemical composition of pure limestone is close to the theoretical composition of CaCO3, with CaO accounting for 56.04% and CO2 for 43.97%. Limestone is a common non-metallic mineral and a valuable resource with wide applications. The applications of limestone covers many fields such as construction, metallurgy, environmental protection, and chemical industry. For example, it is a key material for manufacturing cement, steelmaking flux, flue gas desulfurization, and the production of calcium carbonate.
