Zavedení bentonitu
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.
Distribuce modifikovaného bentonitu a tuzemské zásoby
Modifikovaný bentonit má zlepšit vlastnosti bentonitu s bentonitem jako surovinou. Celosvětově jsou zdroje bentonitu distribuovány především v Číně, Spojených státech, Kanadě, Mexiku, Brazílii, Indii a Japonsku. Čína má bohaté zásoby bentonitu. Osvědčené rezervy jsou na prvním místě na světě. Na většině území naší země jsou ložiska nerostných surovin, soustředěná především v Sin-ťiangu, Kuang-si a Vnitřním Mongolsku. Čína se v posledních letech s roční těžbou bentonitu udržující na cca 5,6 mil. tun stala největším světovým producentem bentonitu, který poskytuje dostatek surovin pro domácí rozvoj modifikovaného bentonitového průmyslu.
Modifikační metody bentonitu
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.
Aplikace bentonitu
Modifikovaný bentonit může být široce používán v polích papír-výroba, potisk a barvení textilu, plasty a ochrana životního prostředí.
Aplikace modifikovaného bentonitu v oblasti výroby papíru
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.
Aplikace bentonitu v oblasti potisku a barvení textilu
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.
Aplikace modifikovaného bentonitu v oblasti plastů
V oblasti plastů lze modifikovaný bentonit použít jako plnivo pro úpravu pryskyřic.
Aplikace bentonitu v oblasti ochrany životního prostředí
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.
