Einführung von Bentonit
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.
Verteilung von modifiziertem Bentonit und inländischen Reserven
Modifizierter Bentonit soll die Leistung von Bentonit mit Bentonit als Rohstoff verbessern. Weltweit sind die Bentonitressourcen hauptsächlich in China, den Vereinigten Staaten, Kanada, Mexiko, Brasilien, Indien und Japan verteilt. China verfügt über reichliche Bentonitreserven. Die nachgewiesenen Reserven stehen weltweit an erster Stelle. In den meisten Gebieten unseres Landes gibt es Mineralvorkommen, hauptsächlich in Xinjiang, Guangxi und der Inneren Mongolei. In den letzten Jahren ist China mit einer jährlichen Bentonitproduktion von etwa 5,6 Millionen Tonnen zum weltweit größten Bentonitproduzenten geworden, was ausreichend Rohstoffe für die inländische Entwicklung der modifizierten Bentonitindustrie liefert.
Modifizierungsmethoden von Bentonit
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.
Anwendung von Bentonit
Modifizierter Bentonit kann in den Bereichen Papier-Herstellung, Textildruck und -färbung, Kunststoffe und Umweltschutz.
Anwendung von modifiziertem Bentonit im Bereich der Papierherstellung
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.
Anwendung von Bentonit im Bereich Textildruck und -färbung
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.
Anwendung von modifiziertem Bentonit im Kunststoffbereich
Im Kunststoffbereich kann modifizierter Bentonit als Füllstoff zur Modifizierung von Harzen eingesetzt werden.
Anwendung von Bentonit im Bereich Umweltschutz
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.
