What is Bentonite Clay Dischem?

Bentonite Clay Dischem, likewise referred to as bentonite, bentonite as well as bentonite, is a clay or clay rock with montmorillonite as the main mineral part. The name provided by the American scholar W.C. Knight in 1898 when he researched the Cretaceous argillaceous rocks near Wyoming, United States. Bentonite Clay Dischem consists generally of hydrous aluminosilicate minerals. Along with the main mineral montmorillonite, it additionally frequently includes clay minerals such as illite, kaolinite, chlorite, halloysite, beidellite, as well as the connected parts include zeolite minerals and also calcite, quartz, feldspar, Glass debris, rock debris, etc.
The main chemical parts of Bentonite Clay Dischem are silica, alumina as well as water, magnesium oxide and also iron oxide are additionally high in material, in addition to calcium, salt, potassium, and so on. Montmorillonite is a hydrous aluminosilicate containing percentages of antacids and alkaline planet steel ions. The unit cell of montmorillonite is 2 silicon-oxygen tetrahedron layers sandwiched by a hydrogen-oxygen octahedron layer. The cation heterovalent isomorphic substitute makes it charge the layer and also has various attributes such as adsorption as well as cation exchange.
Bentonite Clay Dischem can be separated into various properties according to the kinds of exchangeable cations and layer charges of its montmorillonite, such as sodium-based, calcium-based, magnesium-based, aluminum-based, etc, and the properties can likewise be transitioned to each various other, that is, all-natural alteration. Individuals use this particular to synthetically modify bentonite as required in production.

6 Modification Methods of Bentonite Clay Dischem

Because the adsorption capacity of montmorillonite and Ca2+ is stronger than that of Na+, the bentonite existing in nature is generally calcium-based soil. However, in practical applications, it is found that the exchange capacity of Ca2+ in calcium-based soil is much lower than that of Na+. Therefore, calcium-based soil is often put into the market after sodiumization.

The sodium modification is to use the bonding strength of Na+ to Al and Mg to be greater than the bond strength of Ca2+ to Al and Mg, and to achieve the purpose of sodium modification by replacing the Ca2+ between the bentonite layers by Na+.

Commonly used sodiumizing agents are NaF, Na2CO3, NaCl, NaNO3, NaSO4, etc.

The acid modification method mainly uses different types and concentrations of acid to soak the bentonite. At this time, the metal ions such as Al3+, Mg2+, Ca2+ in the bentonite layer are dissolved in the form of soluble salts, so that the pores are dredged, which is beneficial to the adsorbate. At the same time, since the radius of the hydrogen atom is smaller than that of Al3+, Mg2+, and Ca2+, the ionized H+ can replace the metal cations between the layers, thereby weakening the interlayer force and making the permanent negative charge on the Bentonite Clay Dischem band change. It is more conducive to the exchange between cations, so the adsorption capacity is improved.

The acidified Bentonite Clay Dischem is generally called activated clay or bleaching earth, and its pore volume and specific surface area are greatly changed, and the adsorption site is also increased.

Commonly used acid modifiers are H2SO4, HCl, CH3COOH, etc.

The calcination modification method is to calcine Bentonite Clay Dischem at different temperatures. Bentonite will lose surface water, bound water in the skeleton structure, and organic pollutants in the pores in turn when calcined at high temperature, resulting in an increase in porosity and an increase in structure. It is more loose and the specific surface area becomes larger, which improves the adsorption performance to a certain extent.

The basic principle of the organic modification method is to organicize bentonite, and use organic functional groups or organic substances to replace the exchangeable cations or structural water between the layers of Bentonite Clay Dischem, and then form a covalent bond, ionic bond, coupling bond or Van der Waals force. Organic Compound Bentonite.

The organic modifier undergoes ion exchange with cations such as calcium or sodium in the bentonite through ion exchange, thereby introducing organic components into the bentonite, and the modified bentonite changes from hydrophilic and oleophobic to lipophilic and hydrophobic. Organic modification can not only increase the distance between layers of bentonite, but also enhance the ability to remove organic matter.

Commonly used organic modifiers are anionic and cationic surfactants, including octadecyl trimethyl bromide (chloride) ammonium, cetyl trimethyl bromide (chloride) ammonium, cetyl dimethyl bromide Ammonium benzyl bromide (chloride), cetylpyridine chloride, sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, etc.

The mechanism of the inorganic modification method is to use the characteristics of the swelling property of bentonite and the exchangeability of cations between layers, and the inorganic modified bentonite is prepared by making the metal hydroxyl cations generated by the hydrolysis of inorganic metal cations enter the interlayer of the bentonite to replace the exchangeable cations. Methods.

After inorganic modification of natural Bentonite Clay Dischem, the interlayer spacing is significantly increased, the specific surface area is also increased, and the adsorption effect is significantly improved.

Commonly used inorganic modifiers are AlCl3, FeCl3, TiCl4, etc.

The inorganic/organic composite modification method uses the characteristics of the relatively large interlayer gap and cation exchangeability of bentonite. It mainly uses inorganic polymers to open up the interlayer domains, and then uses activators to change the surface properties of bentonite. method.

The commonly used preparation method is to first treat Bentonite Clay Dischem with polyhydroxy cations to increase the interlayer domain of bentonite, resulting in charge reversal, and then adding organic surfactants to change its surface properties.
