Bentonite rock has specific physical and chemical properties. Its business has flourished due to its special properties. Bentonite is a kaolin clay mineral composed primarily of montmorillonite mixed with the related minerals nontronite and beidellite. These are three layers of aluminosilicate with water molecules between the layers. Bentonite is a clay composed primarily of smectite minerals, usually formed from the decomposition of volcanic ash or tuff, or sometimes other igneous or sedimentary rocks.
Bentonite is a highly plastic clay that shrinks (or swells) significantly in response to the removal (or addition of) water For natural sodium bentonite, exchangeable sodium cations predominate over other cations such as calcium and magnesium. Similarly, calcium cations predominate in calcium bentonite. Of all the bentonites available in the world, the sodium variety has the characteristics of high swelling and crystallization properties, good viscosity, and good fluid limit. A variety of bentonite found in different regions in the world. It was probably formed millions of years ago from volcanic ash that fell into stagnant saline water in semi-arid conditions. Due to the natural properties of this volcanic ash, the chemical composition of this particular variety is different from the rest of the world. Most of these deposits are natural sodium bentonite with a higher iron content. Darker in color and with a very fine particle size, this clay mineral exhibits extraordinary bulking capacity and bond strengths. These properties make bentonite applicable in various industries around the world. Moderate swelling of bentonite (average sodium and calcium). Sodium bentonite is the most beneficial because of its high ability to swell. They are mainly used as binding mud in foundries, drilling mud, animal feed pellets, and for civil engineering applications. There are three main types of bentonite: high bloating (sodium) low bloating (calcium)
betonamit vs dexpan
For miners betonmit powder vs Dexpan is about the non-explosive agents present in both minerals . Splitting rock, crushing concrete, mining and extracting stone can be done by betonmit and Dexpan. It has never been easier with Dexpan non-explosive expansive demolition grout, which has been used successfully on hundreds of projects (see galleries below). Dexpan is a powder with an amazing 18,000 psi strength when mixed with water. After pouring into pre-drilled holes, Dexpan can safely and quietly crack concrete and rock while providing silent cracking. It is safe, easy and profitable. Non-explosive destructive agents are chemical substances that replace explosives and gas pressure detonation products in demolition, mining and quarrying. [1] To use non-explosive destructive agents in demolition or quarrying, holes are drilled into bedrock as if using conventional explosives. A thick mixture of non-explosive destruction agent and water is poured into the drill holes. Over the next several hours, the suspension expands, cracking the rock in a pattern somewhat similar to the cracking that would occur with conventional explosives. Betonamate is a non-explosive demolition agent that allows for relatively accurate demolition without the need for special conditions or equipment. It has a very good shelf life of at least 3 years. After a reaction time of only a few hours, the betonamite develops an enormous expansion pressure, which soon becomes so strong that all hard rock and even reinforced concrete crack. Compared to other traditional demolition methods, Betonamit operates almost silently, is vibration-free and is environmentally friendly. Non-explosive destroyers like betonamate and Dexpan offer many advantages, including that they are quiet and do not produce vibrations like conventional explosives do. In some applications, conventional explosives are cheaper than non-explosive destruction agents. These are available in many countries without restrictions, unlike explosives which are highly regulated. These agents are safer than explosives, but must be used as directed to avoid vapor explosions during the first few hours after placement.

physical properties of bentonite
Among the most important physical properties of bentonite, which is used in many different industries, are the following: Water absorption and swelling. The basic property of bentonite is water absorption and expansion. However, not all bentonite has the same absorbent capacity. Its level of hydration and plumpness depends on the type of interchangeable ions it contains, with different capacity for water and solution. The swelling is mainly due to two factors: 1) water uptake at the platelet surface level and 2) extrusive osmotic forces, which force the platelets to separate and open up like a "stack of cards". Sodium bentonite, with a predominance of sodium cations (Na +), allows water to penetrate the platelets, forcing them to separate, causing swelling. On the contrary, calcium bentonite mineral, with a predominance of calcium cation (Ca2 +), although it moisturizes in the same way, due to its strong positive charge, it has lower absorption properties, which prevents water from penetrating the platelets. In the latter case, platelets slough off rather than swell. Viscosity and thixotropy of aqueous suspensions When bentonite disperses in water, colloidal suspensions of high stability, high viscosity and liquefaction are formed. At sufficiently high concentrations, these suspensions begin to acquire gel properties. Suspensions are formed when water molecules penetrate the middle layers of platelets. Here, hydrogen bonds are made up of hydrogen atoms present in water molecules. Platelets separate from each other, while they join through the intervening water. When left still, a network is formed, with the merging of water, gels. Instead, under mechanical stress, these bonds partially break, allowing platelets to move more freely. The viscosity under these conditions is lower than at rest. This reversible sol-gel-sol process is known as thixotropic. These properties shown by aqueous bentonite suspensions are mainly used in drilling muds. Colloidal and waterproofing properties. When bentonite absorbs water, it forms a semi-solid gel with strong resistance to hydrostatic pressure. A sheet of montmorillonite can be decoded as a thin bundle of negatively charged layers. Because of their negative charge, they repel each other, allowing water to pass through. In this way, when the bundle swells, a stable crust forms around the platelets. When saturated, this crust will repel water, even under pressure. Because of all these properties, bentonite is used in ponds and ponds, to seal soil seeps and lining the base of landfills. 
non explosive rock breaking chemicals
Today they use non-explosive rock breaking chemicals in mining industries. Conventional blasting has several drawbacks. Drilling, blasting and reaming operations are complex; Personnel and equipment must be evacuated prior to detonation; safety hazard; The environment was negatively affected. In addition, the use of blasting methods near residential and populated areas requires strict procedures and precautions, which mainly affects the continuity of the rock drilling process. To overcome the disadvantages of conventional blasting and ensure the continuity of the rock exploration process, many modern methods have been developed as practical solutions for rock breaking in accordance with safe and environmentally friendly operating standards. The use of conventional methods of destruction, such as explosives, may not be possible or require special precautions. Non-explosive chemicals operates in a variety of situations where conventional explosives are prohibited or unwanted. Non-explosive chemicals is a safe, non-explosive and cost-effective demolition solution. It can also reduce labor costs and increase productivity while drastically reducing environmental impacts. Newly developed technologies were introduced as unconventional methods for drilling hard rock and concrete and as alternatives to the explosive blasting method. The application of these modern methods in the field of mining also contributes to the continuity of the drilling process, reduces mineral dilution and mineral losses, reduces the amount of labor required and ensures safe conditions for mining operations. Some modern methods such as pumped water and high-pressure gas systems have been reviewed and compared. Hydraulic fluid has been patented for use in hard rock fracturing and has been shown to be effective. Furthermore, extended chemical agents have been identified for the same purposes. Here, the hydraulic splitting method and extended chemical agents are reviewed, highlighting the process of action, applications, and potential efficacy. 
betonamit price
Betonamit price for sale / 5 kg bag is $57.83. Betonamit has been used safely and with excellent results by thousands of contractors and homeowners around the world. Safe use relies on following the instructions and wearing safety glasses at all times. Although bituminous is non-toxic, it is caustic and can cause serious eye injury if splashed in the eye during mixing or pouring. The chemical reaction of betonamate and water generates heat. If this reaction proceeds too quickly, the temperature can rise above the boiling point of water before all of the water chemically combines with the bitonamite. This can result in a steam-driven explosion that expels bitonamite from the crater with sudden force. To avoid bursting, follow directions for mixing water temperatures and hole sizes. Always wear protective eyewear and do not use piercings larger than 1 1/2 inches in diameter. Blow dust out of holes after drilling and keep bitumen emulsion cool before use. 
The features of the holes to put bitonamite are as follows:
- Maximum hole depth is 10 feet.
- The minimum depth of the hole is 4 times the diameter of the hole. For example, 5 with a 1-1/4" hole, 6 with a 1-1/2" hole.
Holes less than 4 times the diameter are more likely to burst.
- In reinforced concrete, 85-90% of its depth is drilled. At the edge, dig as deep as you like to remove it. In rocks, drill 2/3 to 3/4 of the thickness of the rock.
betonamit instructions
There are a few instructions on how to use betonamite. The first step is to drill 1¼”-1” diameter holes. The optimal distance between each well is about 10 times its diameter, and therefore about 30-40 cm. Wells must be clean and dry. Now put BETONAMIT® powder into the mixing bowl. Add 1.0 max. 1.2 liters (per 5 kg) of clean cold water. Blend it with a mixer until it becomes a smooth and homogeneous mixture. Fill the well with the mixture directly. The processing time should not exceed 5 minutes. No additional mechanical seal is required. The following is the list of the holes patterns you need to follow in your instructions. 
- Holes should be drilled to allow a free face of bit bentonite clay to rush into it. For example, drilling at a 45-degree angle into a flat surface from the edge will push it up, but drilling straight down may not allow any places to compress.
- To demolish a slab without pushing on the surrounding walls, drill a cone-shaped pattern in the center and fill these holes first. The cone will pop up and create a free face.
- The hole pattern depends on the tensile strength of what you're breaking, the number of rebars, if any, and the size of the pieces you want when you're done. This can often be determined by experience; A good starting point is to place holes one foot on center in rows one and a half feet apart on center. In unreinforced concrete, holes can be spaced up to 24 degrees apart.
- Hole pattern also depends on how quickly you need results. More holes together will have faster break times and smaller pieces, but this costs more to work with and betonamate.
- Rock is much easier to break than reinforced concrete or edges, and drill holes can be more widely spaced, especially if breaking speed is not critical.
- When removing part of the slab, you must prevent cracks from spreading to the rest of the slab. Drill 6 holes in the center on a line between the "demolition" section and the "retention" section, then fill every third hole. The empty holes form weaknesses and prevent cracks from propagating in the "retainer" section.
- Empty holes can also be used to guide slits; its cost is less than filled holes. For example, if you want to divide a rock into thirds, you can use this pattern.
