Introdução da bentonita
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.
Distribuição de bentonita modificada e reservas domésticas
A bentonita modificada é para melhorar o desempenho da bentonita com bentonita como matéria-prima. Globalmente, os recursos de bentonita são distribuídos principalmente na China, Estados Unidos, Canadá, México, Brasil, Índia e Japão. A China tem reservas abundantes de bentonita. As reservas comprovadas estão em primeiro lugar no mundo. Existem depósitos minerais na maioria das áreas do nosso país, principalmente concentrados em Xinjiang, Guangxi e Mongólia Interior. Nos últimos anos, com a produção anual de bentonita mantendo-se em cerca de 5,6 milhões de toneladas, a China se tornou o maior produtor mundial de bentonita, o que fornece matérias-primas suficientes para o desenvolvimento doméstico da indústria de bentonita modificada.
Métodos de modificação da bentonita
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.
Aplicação de bentonita
A bentonita modificada pode ser amplamente utilizada em campos de papel- fabricação, impressão e tingimento têxtil, plásticos e proteção ambiental.
Aplicação de bentonita modificada na área de fabricação de papel
In the paper-making field, bentonite is used as a multifunctional white mineral filler. It has a large specific surface area, excellent dispersibility, high whiteness, and high purity. It can reduce the water permeability of paper and improve its barrier properties.
Aplicação da bentonita na área de impressão e tingimento têxtil
In the textile printing and dyeing industry, manufacturers use modified bentonite to produce sizing agents and dyes. It plays the role of dispersion, stabilization, and adhesion during sizing and coloring, which can improve the quality and production efficiency of sizing and dyeing.
Aplicação de bentonita modificada na área de plásticos
No campo dos plásticos, a bentonita modificada pode ser usada como carga para modificar resinas.
Aplicação da bentonita no campo da proteção ambiental
In environmental protection applications, engineers use coated bentonite to treat wastewater and exhaust gas, and it adsorbs pollutants such as heavy metal ions, oil stains, and tar.
At present, the demand for high-performance bentonite in many industries is continuously increasing, and modified bentonite has a good development prospect. So how to improve the utilization efficiency of bentonite? For efficient preparation and production, appropriate grinding and classification equipment is essential. Furthermore, specialized modification equipment—used for surface treatment and coating—is particularly crucial to improving and expanding the performance of bentonite. The powder machinery from Qingdao Epic Powder Machinery Co., Ltd. perfectly meets these needs. We provide comprehensive solutions for bentonite, ranging from crushing and classification to surface coating and modification, making us your ideal choice.
