ベントナイトの導入
Bentonite is an important non-metallic mineral, with characteristics of adsorption, expansion and pulping. Its main component is montmorillonite.Driven by the continuous progress of science and technology, the application fields of bentonite are expanding. Meanwhile, the market’s requirements for its performance and quality are constantly increasing, leading to deeper technical research and the emergence of new technologies. Modified bentonite can improve the performance of traditional bentonite and enhance certain characteristics of traditional bentonite. It is an important direction for the diversified and high-end development of the bentonite industry.
改質ベントナイトの分布と国内埋蔵量
改質ベントナイトは、ベントナイトを原料としてベントナイトの性能を向上させるものです。世界的に、ベントナイトの資源は主に中国、米国、カナダ、メキシコ、ブラジル、インド、日本に分布しています。中国はベントナイトの埋蔵量が豊富で、証明済み埋蔵量は世界一です。中国のほとんどの地域に鉱床があり、主に新疆、広西、内モンゴルに集中しています。近年、ベントナイトの年間生産量は約560万トンを維持しており、中国は世界最大のベントナイト生産国となり、国内の改質ベントナイト産業の発展に十分な原材料を提供しています。
ベントナイトの改質方法
The common production methods of modified bentonite mainly include activation modification method and modifier modification method. The activation modification methods include thermal activation, acid activation, hydrogen activation, and salt activation. Among these methods, researchers and industry users more widely apply thermal activation and acid activation. The modifier modification method can use inorganic modifier, organic modifier and composite modifier for modification. Modified bentonite can improve some properties of bentonite, for example, improve its adsorption property, which can accordingly improve its efficiency, enhance its application value, and then expand its application range and demand scale.
