325Mesh Sericite Mica For Plastic Cosmetics

325メッシュセリサイトマイカプラスチック化粧品用

セリサイトは白雲母の亜種で、粒子が小さいため、超微粉末に加工しやすいです。セリサイトは絹のような光沢があり、化学的性質が安定しており、摩耗、酸、アルカリ、紫外線に対する耐性が良好です。また、耐候性と断熱性に優れています。華源セリサイトは高品質の原鉱石を使用して生産されており、均一な粒子分布、高純度、安定した品質を実現しています。セリサイトは、塗料、コーティング、ゴム、プラスチック、セラミック、化粧品、顔料、冶金、溶接などの業界で広く使用されています。プラスチック、コーティング、塗料、ゴムへの機能性充填剤として、機械的強度、粘り強さ、接着力、耐候性、耐腐食性を向上させることができます。乾式粉砕粉末と湿式粉砕粉末の両方が利用可能です。

Processing Technology

There are two manufacturing processes of mica powder: dry grinding and wet grinding. We have our own factories to produce these two products.

Dry ground mica powder is produced by physical grinding without changing any natural property of mica. We adopt total enclosed filling system to guarantee quality during the whole production process. In the screening process,we also employs proprietary equipment and technology to ensure uniform particle distribution and stable quality. As to its superior performance, dry ground Muscovite has been extensively used in production of various products, including fiber cement construction panels / wallboards, plastics, rubber, paint, coating, welding electrodes, oil drilling and brake pads.

● Dry ground process

Wet ground mica powder is produced from natural mica flakes through a series of processes, including cleaning, washing, purification, wet grinding, drying, screening and grading. The unique production process retains the sheet structure of mica , therefore wet ground mica is featured by large radius-thickness ratio, low sand and iron content, high purity, whiteness and glossiness. The unique property of wet ground mica makes it widely used in industries such as paint, coating production, rubber, plastics and ceramics. It is especially effective to improve product's electrical strength, rigidity, heat resistance and to reduce molding shrinkage and cost.
