Physical and chemical characteristics of the activated bleaching clay, application, product features and details

Activated bleaching earth is characterized in that the original soil after dry cleaning or not separation, ensure the attapulgite content of more than 30%, after breaking with dilute acid solution pre heating, activation, at room temperature under mixed boundary without heating, through the method of heat cold acid activation and activation, drying, crushing granulation becomes less than 200 activated bleaching earth product.

Activated Bleaching Clay

 

Product details:

Activated bleaching earth appearance is grey white powder, insoluble in water, oil and organic solvent. With higher efficiency, fast filtering speed, low residual oil rate.

This product can greatly reduce the oil industry, oil production costs, compared with similar products, the amount can be reduced by about 5%, the residual oil and the filtering speed, reduce the rate of filter cake, can completely replace the activated bleaching clay. New decolorization products is a good performance, low price.

Product use:

Lubricating oil, oil refining chemical industry 1, the residual carbon in the lubricating oil in the value, ash, water soluble acid reduced extremely trace, to improve its durability and enhance its ability to resist corrosion.

2, the edible oil industry, for the removal of all kinds of pigment in the oil, and taste, and ion (K +); adsorption, aflatoxin and other harmful substances separation.

3, activated clay industry, mainly for cattle, sheep to make soap and other products of decolorization.

Product features:

The ion exchanged montmorillonite and acid activated the interlayer (calcium, magnesium, potassium, sodium and so on) position by small diameter ion substitution and stripping, the crystal ends pore increases, larger specific surface area. At the same time, because the substitution of hydrogen ion on eight sides or tetrahedral polyvalent ions, resulting in more negative electricity. The acid treated montmorillonite activation becomes activated clay has strong adsorption ability.

Activated Bleaching Clay craftsmanship, bleaching and activation operations

Activated clay is a clay (mainly bentonite) as raw material, the inorganic acid, followed by water rinsing, drying adsorbent made of, look for the milky white powder, odorless, tasteless, non-toxic, strong adsorption, can adsorb colored material, organic matter. Easy to absorb moisture in the air, place too long will reduce the adsorption properties. However, heated to 300 degrees Celsius above began to lose water of crystallization, is the change in structure, effects of fading effect. Senior activated clay products, products for the gray white, pink or white powder or granular, non-toxic and tasteless, insoluble in water, easy to absorb moisture; with larger specific surface area and more active acid center, so the catalytic and adsorptive ability strong, so not only have decolorization ability better, at the same time activity the degree is high, the low rate of oil, filtering speed, is the most ideal bleaching agent.

Use of activated clay widely, in animal and vegetable oil refining industry for the decolorization and purification; in the petroleum industry, used for petroleum resin, wax, paraffin oil, kerosene decolorization and purification; paper industry for paper dyes, dye, fill oil. As a fire extinguisher powder in forestry and water and soil conservation, binder hond elimination of oil in water; used as a catalyst and catalyst carrier in chemical industry, carrier insecticides, pesticides and fungicides, rubber and plastic filler, desiccant and filtering agent, adsorbent radioactive waste; in water purification and sewage treatment as absorbent and flocculant. The use of appropriate heating (80 to 100 degrees) resurrection, if heated to 300 degrees above began to lose water of crystallization, structure change, affecting decolorization.

CA bentonite as raw material, using sulfuric acid as activator, on activated clay production process was studied by orthogonal experiment, and the optimum technological conditions are determined according to the performance of activated product activation. The results show that, the main factors affecting the decolouring ratio as the acidity, liquid to solid ratio, temperature and activation time. Under the optimum conditions, the decolorization of activated clay rate can reach more than 90%.

Key acid clay variable Activated Bleaching Clay is activation of bentonite:

Activation operation 1, bentonite, generally used in sulfuric acid as activator, sulfuric acid consumption in the range 5-25%, liquid to solid ratio in 2-5:1, activation temperature of around 95, the activation time of 4-8 hours.

2, washing acid: bentonite slurry activated containing excess acid, the impact of product use, must be washed to remove, acid reaches the standard. Generally use the rinsing solution acid, each time the amount of water is about 10 times as large as the material, fully stirring settlement) 1-2 hours, the supernatant was removed, rinse 3-5 times, so that the final rinse solution of pH of 4-5.

3, solid-liquid separation and drying

Contain a lot of water slurry after washing, filtration or centrifugal way by dehydration, electric heating drying oven drying, the general temperature at around 105, 2-3 hours.

4, crushing and classification

The dried material agglomeration is more, has a certain hardness, need grinding sieve, obtained for activated clay products, sealing packing.

Activated bleaching clay product performance, features, overview

activated bleaching clay  appearance is grey white powder, insoluble in water, oil and organic solvent. With higher efficiency, fast filtering speed, low residual oil rate.

This product can greatly reduce the oil industry, oil production costs, compared with similar products, the amount can be reduced by about 5%, the residual oil and the filtering speed, reduce the rate of filter cake, can completely replace the activated carbon. New decolorization products is a good performance, low price.

Activated Bleaching Clay

Activated bleaching earth function:

1, selective adsorption ability, the decolorization rate high, with a low rate of oil, filtration speed, add less;

2, effectively remove grease total phospholipid, soap and trace metal ions, is a natural antioxidant;

3, after bleaching not rise, do not back color, clear and transparent, stable quality,Acid number long shelf life.

4, especially suitable for mineral oil, vegetable oil, animal oil.Refining production

Activated bleaching earth scope:

Animal and vegetable oil refining, for the decolorization and purification, remove harmful pigment, oil phospholipid, saponin, cotton acid, making high-grade edible oil.

In the petroleum industry for refining decolorization and purification as well as petroleum cracking of paraffin wax, oil, grease, kerosene and other minerals.

In the food industry, as Wine and sugar juice clarifying agent, stabilizing, beer saccharification processing, the syrup purification etc..

In the chemical industry, as a catalyst, filler, desiccant, adsorbent, wastewater treatment.

Product features:

The ion exchanged montmorillonite and acid activated the interlayer (calcium, magnesium, potassium, sodium and so on) position by small diameter ion substitution and stripping, the crystal ends pore increases, larger specific surface area. At the same time, because the substitution of hydrogen ion on eight sides or tetrahedral polyvalent ions, resulting in more negative electricity.
