What is spherical silica powder ？
Spherical silica powder is a spherical silicon dioxide material. It has excellent properties and important applications. The particles are regular spheres. Compared to irregular silica, spherical silica powder perform better. It usually has high purity and narrow particle size distribution. It also shows good whiteness. Its flowability is excellent, and dispersion is good. These properties help it disperse evenly in various materials. This promotes its functional performance effectively. The preparation methods of spherical silica can be roughly divided into two categories: physical method and chemical method. This depends on whether chemical changes occur during preparation. Physical method Ball milling Uses grinding and classifying equipment to produce ultrafine powder.Based on material […]
How can powders improve the problem of cosmetics not being skin-friendly?
With the popularity of makeup, powder usage in cosmetics is growing. Cosmetics powders fall into four main categories. These are pigment powders, white powders, filler powders, and pearlescent powders. Pigment powders are used to adjust cosmetic color tones. White powders provide coverage, whitening, and UV protection. Filler powders vary and serve multiple functional roles. They enhance spreadability, absorption, adhesion, and texture. They also reduce visual focus and carry active ingredients. Pearlescent powders add shine and improve product texture. Skin-feel enhancing powders are gaining attention across skincare, makeup, and sunscreen. They include inorganic, organic, and natural powders. Inorganic skin feel improving powder Silicon dioxide Silica powders, chemically known as silicon dioxide, […]

Diamond Micro Powder: Applications in Precision Machining
Diamond, commonly known as “diamond drill,” is a mineral composed of carbon atoms. It is an allotrope of graphite, with the chemical formula C, and is the natural form of what we typically recognize as a diamond. Diamond is the hardest naturally occurring substance on Earth. Diamond micro powder is mainly divided into three types: single-crystal diamond micro powder, polycrystalline diamond micro powder, and nanodiamond micro powder. Additionally, there are other types, such as pseudo-polycrystalline diamond micro powder and agglomerated diamond micropowder. It has has high hardness and wear resistance.This makes it ideal for cutting, grinding, drilling, and polishing. It is especially suited for hard materials like cemented carbide, ceramics, […]
How to Choose an Ultrafine Powder Milling Process and Equipment
Ultrafine powder milling technology is called a cross-century high-tech by scientists worldwide. After refinement, material properties change significantly. Optical, electrical, magnetic, and mechanical properties are affected. Thermal, surface, and interface characteristics also change. Extraordinary effects are often achieved in use. Ultrafine powder milling is usually divided into micron-grade, submicron-grade and nano-grade powders. The international scientific community usually calls ultrafine powders with a particle size greater than 1μm micron-grade powders. Powders with a particle size of 0.1-1μm (i.e. 100nm-1000nm) are called submicron-grade powders. Powders with a particle size of 0.001-0.1μm (i.e. 1nm-100nm) are called nano-grade powders (also known as nanomaterials). In a broad sense, nanomaterials refer to materials with at least […]
ホワイトカーボンブラック：用途とD97処理
White carbon black is modified silicon dioxide, which is a general term for white powdered X-ray amorphous silicic acid and silicate products. It mainly refers to precipitated silica, fumed silica and ultrafine silica gel. It also includes powdered synthetic aluminum silicate and calcium silicate. White carbon black is a porous substance, composed of SiO2·nH2O. Here, nH2O exists in the form of surface hydroxyl groups. It dissolves in caustic alkali and hydrofluoric acid, but insoluble in water, solvents, or acids (except hydrofluoric acid). It is heat-resistant, non-combustible, odorless, and has excellent electrical insulation properties. Element White carbon black is mainly divided into precipitated and fumed silica based on production methods. Fumed […]

シリコーン接着剤のコスト削減のため、ナノカルシウムの一部を改質重カルシウムで置き換える。
Silicone sealants contain various fillers. These include silicon dioxide, nano calcium carbonate, wollastonite powder, and heavy calcium carbonate. Nano calcium carbonate is the most common one used. In the domestic sealant market, over 60% of silicone sealants contain nano calcium carbonate. This usage is quite significant. Nano calcium carbonate is a key filler in silicone sealants. It boosts adhesion, weather resistance, and mechanical performance. This includes improvements in elastic modulus and elongation at break. Its small particle size, high surface area, and surface energy are the reasons for these benefits. Modified heavy calcium carbonate undergoes a special process. This improves the shape, dispersibility, and surface activity of the particles. It […]
ジェットミル法によるPEワックス微粉末製造の利点
Jet milling is the best way to micronize polyethylene (PE) wax into a fine powder. It offers unique technical advantages and process benefits. The technology is great at making uniform, fine particles that range from 2 to 10 microns. It also keeps the material’s thermal integrity intact. Research shows that jet milling offers great control over particle size. It generates little heat and lowers the risk of contamination.
