Introductie van bentoniet
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.
Verdeling van gemodificeerde bentoniet en binnenlandse reserves
Gemodificeerd bentoniet is om de prestaties van bentoniet te verbeteren met bentoniet als grondstof. Wereldwijd worden bentonietbronnen voornamelijk gedistribueerd in China, de Verenigde Staten, Canada, Mexico, Brazilië, India en Japan. China heeft overvloedige bentonietreserves. De bewezen reserves staan op de eerste plaats in de wereld. Er zijn minerale afzettingen in de meeste gebieden van ons land, voornamelijk geconcentreerd in Xinjiang, Guangxi en Binnen-Mongolië. In de afgelopen jaren is China, met een jaarlijkse output van bentoniet van ongeveer 5,6 miljoen ton, 's werelds grootste producent van bentoniet geworden, wat voldoende grondstoffen levert voor de binnenlandse ontwikkeling van de gemodificeerde bentonietindustrie.
Modificatiemethoden van bentoniet
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.
Toepassing van bentoniet
Gemodificeerde bentoniet kan op grote schaal worden gebruikt in de volgende sectoren: papier-fabricage, textielbedrukken en verven, kunststoffen en milieubescherming.
Toepassing van gemodificeerd bentoniet in de papierfabricage
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.
Toepassing van bentoniet op het gebied van textielbedrukking en -verven
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.
Toepassing van gemodificeerd bentoniet in de kunststofsector
Op het gebied van kunststoffen kan gemodificeerd bentoniet worden gebruikt als vulstof voor het modificeren van harsen.
Toepassing van bentoniet op het gebied van milieubescherming
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.
