Anti leakage Bentonite Assists Water Conservancy Engineering Construction
In recent years, water conservancy engineering construction has become increasingly important, but in actual construction, water leakage problems in hydraulic structures are also common. In order to solve this problem, leak proof bentonite has emerged. Anti leakage bentonite is a special type of soil with strong plasticity, formed by adding chemical substances for treatment, and has excellent anti-seepage effect.

Product Introduction of Bentonite for Drilling Fluid
Drilling fluid is an indispensable chemical in petroleum exploration and drilling. Its main function is to cool and lubricate the drill bit, while preventing wellbore collapse and maintaining the stability of the drilling process. The composition of drilling fluid varies depending on specific needs, but usually includes water, mud, and other chemical additives. Among them, bentonite is one of the most commonly used components in drilling fluids.

The Functions, Countries of Use, and Characteristics of Bentonite.
Bentonite is a type of soil that has many important uses and plays a vital role in many industries. Bentonite typically refers to a highly absorbent, swelling clay mineral that can expand and form a highly adhesive gel-like substance when exposed to water. Here are some specific functions, countries of use, and characteristics of bentonite.

Overview of Bentonite for Foundry
Foundry basics.
Currently, the total proven reserves of bentonite in the world are about 2.5 billion tons, with the largest reserves in the United States, China, and Russia, accounting for about 3/4, followed by Spain, Greece, and Germany.
Calcium based bentonite accounts for about 70 to 80% of the world’s bentonite deposits, while sodium based bentonite has a small reserve, mainly in the western state of Wyoming in the United States. Therefore, it is commonly referred to as western bentonite in the United States.
Currently, the annual production of bentonite in the world is about 10 million tons, including about 5-6 million tons in the United States, 2.5-3 million tons in China, 600000 tons in Japan, and about 500000 tons in Spain, Greece, and Germany.
In Japan, the annual consumption of bentonite is about 800000 tons, with the foundry industry accounting for about 35% of the consumption. Japan imports about 200000 to 220000 tons of bentonite from the United States and China each year. -
Overview of Bentonite Mineral Resources
Bentonite is the most developed and utilized mineral among non-metallic minerals, and is now widely used in fields such as oil mining, directional crossing, steel casting, metallurgical pellets, chemical coatings, composite fertilizers, sizing, rubber, plastics, papermaking, water purification, moisture absorbents, pesticides, and other fields

The lifeblood of the petroleum industry, see what role bentonite plays in drilling
Bentonite is known as the “blood” of the drilling industry, and its quality can directly affect the “success or failure” of drilling engineering. High quality bentonite can produce high-quality mud, effectively prevent hole collapse, protect the borehole wall, cool the drilling tool, lubricate the drill pipe, balance surface pressure, and improve drilling efficiency. Therefore, bentonite is an ideal drilling slurry wall protection material, which plays a very important role in various oil and gas drilling wells. Below, we will mainly discuss the “main role of bentonite in drilling”.

Use and processing equipment of bentonite
Bentonite is a non-metallic mineral whose main mineral component is montmorillonite. Bentonite is also known as bentonite, bentonite, or bentonite. It is an aqueous clay mineral mainly composed of montmorillonite, with a hardness of 1-2 and a density of 2-3 g/cm.

High sodium-based content, high viscosity, strong adsorption, sodium-based soap clay
Non-metallic minerals with montmorillonite as the main mineral composition.
Bentonite is a non-metallic mineral with montmorillonite as the main mineral component, montmorillonite structure is composed of two silicon-oxygen tetrahedron sandwiched with a layer of aluminum oxygen octahedron composed of 2:1 crystal structure, due to the layered structure formed by montmorillonite unit cells There are certain cations, such as Cu, Mg, Na, K, etc., and these cations and montmorillonite unit cells are very unstable, easy to be exchanged by other cations, so it has better ion exchangeability. Foreign countries have been applied in more than 100 departments in 24 fields of industrial and agricultural production, with more than 300 products, so people call it “universal soil”.

Manufacturers wholesale salt resistant trenchless pipe drilling bentonite
Trenchless is actually a construction method in daily engineering, such as horizontal drilling construction, pipe jacking construction, oil drilling, geological exploration and tunnel shield machine construction. Projects that do not carry out underground construction by excavating the ground are called trenchless projects. In trenchless projects, trenchless bentonite plays a key role.
