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 […]

Pigment powders adjust the color of cosmetics.White powders provide coverage, whitening, and UV blocking. Filler powders regulate product spreadability, adsorption, skin adhesion, texture, and active ingredient loading. Pearl powders enhance product gloss and texture. Physical Powder – Common Inorganic Powder Skin Care – Scrub, Soap, Shower Gel, Talcum Powder Mica Powder:Mica powder is a group of composite hydrated aluminum silicate salts, a light gray, flaky crystalline powder. It has strong adhesion, moderate gloss, and a smooth feel. Special processing creates synthetic mica, enhancing brightness, whiteness, and durability in cosmetics. It is mainly […]
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. It is an indispensable basic raw material for industrial development. It […]
粉体用ボールミル
Ball mill is a key equipment for crushing materials after they are broken. Ball mill for powders is one of the high-fine grinding machines widely used in industrial production. It is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials, and chemical industries. Why is it Called a “Ball” Mill? What Does “Ball” Mean? The ball mill crushes materials through grinding media. The transmission mechanism transfers mechanical energy to the grinding media. Various mechanical forces generated between the media crush the materials. The grinding media loaded in the mill are mainly steel balls (steel sections), hence the name “ball mill.” Ball Mill […]
重質カルシウム超微粉末処理装置
There are many types of heavy calcium ultrafine processing equipment. They work with ultrafine classifiers to form ultrafine processing systems. These systems can generally achieve ultrafine production results. Currently, the mainstream demand in the calcium market is 600-1500 mesh heavy calcium products. The added value of heavy calcium products is low (compared to talc, barytes, kaolin, etc.). Scale is one of the main factors affecting efficiency. Today, we will discuss the ultrafine processing equipment used in the dry process of heavy calcium. Heavy Calcium Ultrafine Processing Equipment Comparison of Various Ultrafine Processing Equipment Device Type Product fineness (mesh) Optimal fineness (mesh) Advantages Disadvantages Raymond mill 100-1250 <400 Great advantages in […]
What is the Preparation Technology of Barite Powder?
Barite powder is derived from the mineral barite, composed of barium sulfate (BaSO₄). It forms in low-temperature hydrothermal veins and sedimentary rocks. The chemical composition includes 65.7% BaO and 34.3% SO₃. Substitutions of Sr, Pb, and Ca can also occur in its structure. Barite powder typically appears as plate-like, granular, fibrous aggregates, and crystal clusters. Some forms are dense, massive, cryptocrystalline, or soil-like. Stalactites and nodules with concentric band structures can also be found. Barite Mineral Characteristics and Classification Barite is divided into high-purity barite, ultra-fine barite, and ultra-fine active barite. Preparation Technology of Barite Powder Preparation Technology of High Purity Barite Powder Physical purification：Hand selection: Select blocky barite based […]
