珪藻土：自然界の「多孔質の妖精」
In the vast universe of chemical raw materials, there exists a gift from ancient marine life — diatomaceous earth (DE). Though it appears unremarkable, its unique properties make it an indispensable “behind-the-scenes hero” in countless industrial processes. Today, let’s uncover the secrets of this “natural filtration master” and explore how it shines in modern industry. Decoding Its Performance: The “Hardcore Strength” of Diatomaceous Earth 1. Naturally Porous “Skeleton” — Exceptional Adsorption Power Structural secret: Composed of the fossilized silica cell walls of diatoms (single-celled algae) that lived millions of years ago. These micro shells feature extremely fine, uniform, and interconnected pores.Key advantage: This structure gives DE an enormous specific surface […]
シリカの表面改質について、あなたはどれくらい知っていますか？
Silica, also known as silicon dioxide, is an important inorganic chemical raw material. Due to its unique surface structure and particle morphology, silica exhibits excellent stability, reinforcing capability, thickening behavior, and thixotropy. These properties make it a crucial inorganic filler in many fields such as rubber, coatings, and plastics. However, to fully unlock its potential and enhance compatibility with various organic matrices, the surface modification of silica is often employed. This process is key to tailoring its properties for specific applications. Surface Modification of Silica The internal polysiloxane structure and surface-active silanol groups make precipitated silica highly hydrophilic, resulting in poor wettability and dispersibility in organic phases. The hydroxyl groups […]
高純度アルミニウム粉末とは何ですか？
In high-precision manufacturing industries such as semiconductors, electronic packaging, new energy, 3D printing, and vacuum coating, high-purity aluminum powder is playing an increasingly critical role.As industries demand higher conductivity, film-forming ability, and material purity, traditional “industrial aluminum fines” can no longer meet these stringent requirements — giving rise to high-purity aluminum powder. Definition of High-Purity Aluminum Powder High-Purity Aluminum Powder (HPA) refers to a fine metallic powder with aluminum content of ≥99.9% (3N and above), featuring extremely low impurity and gas content. It usually appears as spherical or near-spherical particles ranging from 10–150 μm, with some products reaching the nanometer scale. Unlike ordinary industrial aluminum powder, high-purity aluminum powder emphasizes […]

In the field of new materials, there exists a key additive known as the “MSG of industry” — PTFE wax powder. This white, powdery resin is produced by coagulating, washing, and drying a dispersion obtained through the controlled polymerization of tetrafluoroethylene. It possesses exceptional properties such as heat resistance, weatherability, cold resistance, low friction, non-stick characteristics, chemical stability, and electrical insulation. In addition, due to its small average particle size, PTFE wax powder has excellent dispersibility and can easily blend uniformly with other materials. Production Processes of Wax Powder Physical Method Wax powder can be obtained through mechanical or jet mill, evaporation and precipitation, or melting processes. For example, paraffin […]
