Q:How to increase the swelling effect of sodium based bentonite
1, the montmorillonite content and cation exchange capacity of bentonite ore can be confirmed, and the amount of sodium carbonate can be reasonably added.2, the sodium conditions, moisture, temperature, shear force, extrusion pressure four should be reasonably applied.3, production process: raw ore, testing, coarse crushing, batching, sodium, drying, crushing, testing.4, as far as possible in the ingredients without organic additives, not high temperature.
Q:How to determine the amount of blue absorbed by Bentonite
So we can use the adsorption capacity for methylene blue (hereinafter referred to as the methylene blue absorption, the unit is g / lOOg clay) to the identification of bentonite quality. China's Shenyang Research Institute of Foundry without spectrophotometer or colorimeter, but with a 2O standard solution of different concentration, many kinds of bentonite produced per 100g ceiling how many grams of blue [5]. Germany has used similar methods for the determination of a sand bentonite bentonite containing different amount of light transmission rate as the control curve with visual method, which can detect the effective bentonite content. To measure the sand in Shenyang tractor factory using visual colorimetric method to detect the adsorption capacity of the United States had used methylene determination of montmorillonite and blue medicinal ceramic raw materials in green sand effective bentonite content of [7].2O in the early 5O century. Until 6O in the mid-1990s, the United States engaged in oil drilling industry National Lead Co.BaroidDiv. published an article that The difference between method [8~11]. and absorption blue colorimetric method for the determination of Bentonite on the successful application of titration method to sample liquid dispersed gradually in the instillation of methylene blue solution. If you add all of methylene blue adsorbed bentonite is free of methylene blue does not exist in a sample liquid such as adsorption swelling fruit. Bentonite has been saturated, free of methylene blue to sample liquid, then that has reached the end point. So that the adsorption capacity of methylene blue solution. End point judgment is on the sample liquid drops on the paper, halo mud observation filter leakage around the blue and green colors.
Q:4800/m2 bentonite cushion what quota
Bentonite waterproof mat (GCL) is a new type of Geosynthetics
Q:Can bentonite be used as expansion agent?
Calcium sulphoaluminate - calcium hydroxide expansive agent for concrete and cement, refers to water mixing after hydration ettringite and hydrated concrete expansive agent.
Q:Why does the drilling fluid increase with the increase of the apparent viscosity of bentonite?
More bentonite, adsorption of water more, free water less, high viscosity; more bentonite, solid phase friction, and high viscosity;
Q:The waterproof blanket with bentonite is waterproof to the man-made lake, but the seepage is very serious
After the construction of bentonite waterproof blanket, the construction personnel must pay attention to prevent the damage of bentonite cushion. 5, in order to prevent the early hydration due to rain, cushion construction should be laid 3-5cm thick cement mortar, in order to prevent waterproof layer contact with water and early hydration. General muddy concrete compaction total amount not less than 10cm.
Q:Most people have to buy cat bentonite cat litter, but it is easy to be the cat lapped. What about licking?
It shouldn't be a problem because the cat itself will vomit, just like licking its own hair. I got a kitten and ate all the threads. There is nothing wrong with the back, all out of their own, there is no exception.If you are worried, you should pay attention to the mental condition and eating situation every day.
Q:Sodium bentonite and sodium bentonite clay has the difference? What is the processing method of sodium bentonite?
First of all, determine your mineral source taste --- cation exchange capacity. Define the process against your customer requirements, standards, and prices. Sodium based bentonite is usually replaced with soda ash on a calcium based bentonite. There are dry and wet methods.
Q:What do you mean by "200 eye bentonite" in the data?
Particle size of powder is called particle size. As the particle shape is very complex, usually there are several screening methods, such as particle size, sedimentation particle size, equivalent volume size, equivalent surface area, particle size and so on. The granularity is particles can be obtained by screen mesh size, with 1 inches (25.4mm) the number of mesh width of the screen mesh representation, so called "mesh". At present, there is no uniform powder particle size standard at home and abroad, and each enterprise has its own definition and representation of particle size index. In different countries and different industries, the screen specifications have different standards, so the meaning of "target" is difficult to unify.
Q:What's the influence of Bentonite on the grouting when the shield construction is stopped?
A note about the impact of this technique is that the bentonite slurry must be mixed evenly, also stop too long, always move the pump, is to avoid the bentonite slurry itself or precipitation, dry caking
We have our own mines of bentonite, Kutch bentonite is famous in the world for it's extra ordinary quality. We have all grades in bentonite like cat litter, foundry, OCMA, API 13 A, DFCP-4, paint etc, We have our production plant in Kutch-Gujarat with in house r & d house and have well trained technical team, we can also provide bentonite lumps and granules also.We also trade in kaolin powder and lumps.
