Q:Is Peng Runtu and talc an ore?

The bentonite is non metallic mineral montmorillonite as the main mineral composition, structure of montmorillonite is 2:1 type crystal structure of [1] consists of two silicon oxygen tetrahedron sandwiching a layer of aluminum eight surface body composition, due to the layered structure of montmorillonite crystal cell formation in the presence of some cations, such as Cu, Mg, Na, K, and the cation with montmorillonite crystal cell function is not stable, easy to by other cation exchange, so it has good ion exchange property. Foreign countries have already applied 24 fields and more than 100 departments in industry and agriculture. There are more than 300 products, so people call it "omnipotent soil"".

Q:What is better, such as needling method, sodium base swelling method, needle coating method and adhesive waterproof blanket in Na bentonite?

Fordated documents, subsequent amendments (excluding corrections) or revisions do not apply to this standard, however, encourage the latest version of the parties to agreements based on this standard using these files. Any undated reference document whose latest edition is applicable to this standard.

Q:Is sodium bentonite organic or inorganic?

Na based bentonite, calcium based lithium based magnesium based bentonite are inorganic compounds. Organic soil is an organic coupling coating on the molecular surface of sodium bentonite

Q:What is the density of bentonite, that is, how heavy is one?

The density of the bentonite is 2~3g/cm3, or 2000kg~3000kg/m3.Bentonite is also called K-bentonites, universal soil, bentonite and bentonite rock, non-metallic mineral montmorillonite as the main mineral components (montmorillonite in 85-90%). The structure of montmorillonite is 2:1 type crystal structure consists of two silicon oxygen tetrahedron sandwiching a layer of alumina eight body composition, due to the layered structure of montmorillonite crystal cell formation in the presence of some cations, such as Cu, Mg, Na, K, and the cation with montmorillonite crystal cell function is not stable, easy to by other cation exchange, it has good ion exchange.

Q:In general, in the shield tunnel, bentonite is used to improve the soil?

On the other hand, due to the timely filling, only to play a good supporting and supporting role, several ring segments to strengthen, reducing the possibility of moving links, thereby reducing the part of the thrust under the crack and possible dislocation.To improve the method of mining sand and gravel silt soil is injected into the chamber of bentonite mud bentonite (mud) system, waste plastic liquidity good, correct consistency, low permeability, Morocco resistance, smooth slag, earth pressure balance control. Typical construction of Beijing shield is sand and gravel layer, each bored ring (1.2 meters), bentonite mud injected 4 square meters. Not only to the mud party requirements and the effect of mud higher requirements. After engineering practice, the proportion of mixing mud 1.07, kinematic viscosity, so that muck improve more than 35 seconds, in order to achieve the best results.

Q:Difference between expansion factor and expansion capacity

The expansion factor is the ratio of the volume of material to the volume before expansion. Expansion said expansion properties of ore, the vitreous transparency, it is constructed with pearl ore development degree, water level, water and impurities in the raw material and process control factors, evaluation of expanded perlite and vermiculite is the main technical indexes of ore expansion. It is also an auxiliary index to evaluate the properties of Bentonite for casting.

Q:Mud bentonite for Bored Pile

The mud is used to clear the cuttings, expel the gas, and then from the mud tank to the borehole, limiting the water in the formation into the borehole. An impermeable layer is formed on the hole wall to prevent water from entering the formation by drilling fluid. This thin impermeable layer has a certain strength and toughness. Only in this way can the corrosion of the borehole be prevented and the corrosion of the drill rod caused by grinding is prevented. During drilling, the change of electrolyte concentration requires little change in viscosity and thixotropy of the mud. This is not available in general mud, so the bored piles should be made of mud bentonite

Q:How to improve the viscosity of bentonite? Is there any tackifier added to bentonite which can be quickly lifted?

The choice of additives is very important. The adulteration of cellulose (anhydrous and amide) instant critical amide. Plant glue positive glue cost is high!

Q:The distinction between bentonite and attapulgite and their respective uses

Is a non-metallic mineral montmorillonite as the main mineral composition, structure of montmorillonite is 2:1 type crystal structure consists of two silicon oxygen tetrahedron sandwiching a layer of alumina eight body composition, due to the layered structure of montmorillonite crystal cell formation in the presence of some cations, such as Cu, Mg, Na, K, and the cation with montmorillonite crystal cell. Is not stable, easy to by other cation exchange, so it has good ion exchange property. Foreign countries have already applied 24 fields and more than 100 departments in industry and agriculture. There are more than 300 products, so people call it "omnipotent soil""

Q:How to distinguish the quality of montmorillonite?

Montmorillonite is natural layered silicate nanocomposites, the thickness of each layer is only 1 nm, smaller particle size, large surface area, covering 1 per gram of powder can be the size of a basketball court surface can strengthen the digestive tract, mucosal barrier function; uneven charge characteristics and montmorillonite, can adsorb many kinds of virus, bacteria and its suppression the toxins produced by the balance of normal flora, improve the immune function of the digestive tract. Therefore, montmorillonite more attention are used in medicine, veterinary medicine and feed market, the so-called "montmorillonite" products and raw materials are more and more, using bentonite as dragons and fishes jumbled together, montmorillonite is There are plenty of people who will have a customer dahushangdang, from time to time.
