Q:Putty powder with bentonite what are the benefits?

The main function of bentonite in coating and putty powder is to increase thixotropy and water holding and drying. At the same time, it is also a cheap filler.

Q:How can the solution be solved if the bentonite is not stirred?

The mud bentonite producers added too many polymers (such as amides), which were not easily dispersed.

Q:What is the influence of sodium temperature on the swelling force of bentonite?

The orebody of the geographical environment is different, exchangeable cation types contained between layers are very different, the physicochemical properties of bentonite are very different. The use of artificial methods to change the interlayer cation to change the physical and chemical properties known as artificial modification, or modified bentonite. The general is ca bentonite, its performance is not ideal, through artificial modification into acid clay, sodium bentonite, lithium bentonite, organic bentonite and high pure bentonite gel. The deep processing of bentonite products has good adsorption, swelling, thixotropy, thickening and a series of physical and chemical properties, widely used in the fields of oil industry, paint industry, textile industry, daily chemical industry, environmental protection and so on.

Q:What are the functions and uses of bentonite waterproof blanket?

Sodium bentonite can absorb 5 times its weight in water, can be expanded to about its volume of about 13-16 times, but also has high water density and self repair, recovery function, expansion after packing to 2 mm -5 mm wide cracks. In theory is the most close to the perfect waterproof material.

Q:What's the use of the bentonite in the fish stuff?

Anti caking effect especially in processing of trace element premix raw materials, there are a lot of water containing highly crystalline salts, and is easy to absorb water, adding bentonite, anti caking effect is very obvious, even in a high humidity in southern coastal areas, the effect is quite good. For general feed anti caking agent, the amount of 1% ~ 3% can be; as a premix anti caking agent, add 3% ~ 5%, the effect is good, and use 10% or more may as well. Three is adsorption. Bentonite can adsorb water and harmful gas, harmful bacteria, play a role in inhibiting gastrointestinal diseases, indirectly play a role in nutrition and health care, while absorbing ammonia and other odor gases, play a role in improving the environment. Recent studies have confirmed that bentonite has unique adsorption, buffering and ion exchange characteristics, which can promote and improve the digestion and metabolism process of animal organism. According to the research we draw the following conclusions: years of bentonite is not only the animal must source of minerals, and is one of the main additives, has high nutritive value and certain stability, a certain role in the prevention and medical treatment.

Q:The action of adding sodium bentonite into cement

The lubrication of bentonite, sealing adhesion, thickening and gelling made of mud, used for lining various operations such as soil seepage, wall construction, grouting, pile, caisson, anti-seepage cement and concrete construction land, additive, solid water transport, sewage treatment and shield lubrication etc..

Q:Can bentonite be used as a bearing layer?

In civil engineering structural design, in the foundation design, the soil layer which directly bears the foundation load is called the bearing stratum. Concrete made of bentonite and cement and sand can be used as bearing layer.

Q:How to determine the amount of blue absorbed by Bentonite

The test method is mainly clay drying after adding sodium pyrophosphate to the clay crystal layer dispersed. Then add excess clay to the methylene blue dye adsorption. The supernatant was then fully separated using film and particle filter or centrifuge, to exclude the interference of sand particles on the test results. The supernatant was diluted with distilled water the suitable concentration was determined by spectrophotometer, we can calculate the amount of clay adsorption of methylene blue. The results showed that the adsorption capacity of bentonite methylene blue clay mineral montmorillonite as the main components, and in accordance with the adsorption capacity for methylene blue illite and kaolinite clay mineral is very small, the adsorption amount of quartz sand very little.

Q:Earth pressure balance shield machine in the excavation, under what circumstances with bentonite, under what circumstances use foam?

Suitable for the use of modified foam formation (1) foam is more suitable for the soil in grading is relatively good for soil particles with good gradation, the particle size distribution of a wide range, and the size of the bubble itself is not uniform, it is easier to fall between soil particles in the pores, closer contact with soil particles. The rate of dissipation of foam in a simple two-phase (water + gas) is much higher than the rate at which it dissipates in a three-phase (soil + water, ten gas). This is because in the soil, the full contact of foam and soil particles can prevent the flow of liquid film from being blocked and reduce the possibility of liquid film dewatering and foam bursting. In the soil gradation is relatively good, because the bubble and soil particles combine more complete and dense, pore water can more fully in the soil replacement and filling the original pore, so easy to form more closed bubbles. It is because of the existence of a large number of enclosed foam that the permeability coefficient of soil is reduced and water retention is enhanced. (2) foam is more suitable for the soil with larger average particle size; the finer the particle of soil is, the closer it is to viscosity; the stronger the hydrophilicity of minerals is, the greater their suction force is. Obviously, the small particles of silty clay will adsorb the free water contained in the liquid film on the surface of the foam, which will lead to the collapse of the foam after the dehydration of the liquid membrane, and reduce the sealing performance of the mixed soil

Q:How to distinguish the authenticity of montmorillonite?

There are many harmful non mineral constituents, but the most harmful ones found in the bentonite are at presentFang Yingshi is a cancer causing substanceThe other is harmful to human understanding of the late stone, Germany in 2005 before it is I. The category of carcinogensFang Yingshi is the poor crystalline morphology of minerals, a reduction in acid or alkaline conditions, can enter the human body; others say lead gilts endometritis cristobalite mycotoxin containing products, increase the cost of cleaning house.
