Introdu\u00e7\u00e3o da bentonita<\/strong><\/h2>

Bentonite is an important non-metallic mineral<\/a>, with characteristics of \u00a0adsorption, expansion and pulping.\u00a0 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\u00a0of traditional bentonite. It is an important direction for the diversified and high-end development of the bentonite industry.<\/p>

A bentonita modificada \u00e9 para melhorar o desempenho da bentonita com bentonita como mat\u00e9ria-prima. Globalmente, os recursos de bentonita s\u00e3o distribu\u00eddos principalmente na China, Estados Unidos, Canad\u00e1, M\u00e9xico, Brasil, \u00cdndia e Jap\u00e3o. A China tem reservas abundantes de bentonita. As reservas comprovadas est\u00e3o em primeiro lugar no mundo. Existem dep\u00f3sitos minerais na maioria das \u00e1reas do nosso pa\u00eds, principalmente concentrados em Xinjiang, Guangxi e Mong\u00f3lia Interior. Nos \u00faltimos anos, com a produ\u00e7\u00e3o anual de bentonita mantendo-se em cerca de 5,6 milh\u00f5es de toneladas, a China se tornou o maior produtor mundial de bentonita, o que fornece mat\u00e9rias-primas suficientes para o desenvolvimento dom\u00e9stico da ind\u00fastria de bentonita modificada.<\/p>

M\u00e9todos de modifica\u00e7\u00e3o da bentonita<\/strong><\/h2>

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.<\/p>
