Bentonite chemical | Organophilic Clay

The processing of Bentonite chemical is to use various methods to improve the quality of natural bentonite clay, change its original structure and chemical composition, obtain its stable and good physical and chemical properties, and constantly expand its role in the application field.

Its entire processing methods, including purification and modification, etc.

The purification methods of Bentonite chemical clay are generally achieved through physical or chemical purification methods, so physical purification is usually achieved through mineral processing purification methods.

The organic bentonite we use in oilfield drilling is achieved by dividing it into two royalty methods.

However, the production cost of wet purified organic bentonite during the production process is higher than that of the dry process method.

The first step is to select high-quality Bentonite chemical from the raw bentonite ore, then crush it, dry it, and then perform wet or dry treatment, followed by film treatment of the powder, and finally package it.

Of course, some soft bentonite do not need to be crushed, and only hard bentonite needs to be molded using a crusher.

Part of our organic Bentonite chemical is extracted by dry, which is a common purification method at present, and it is also suitable for some high content of montmorillonite.

The raw ore is used to produce organic bentonite additive, and its particle size is relatively fine.

The production process of dry processing for organic bentonite additive  is basically based on selecting high-quality organic bentonite raw ore for natural drying, and then crushing it with a crusher.

During airflow drying, this step is also very important. Then ground into powder and subjected to wind sorting classification, and finally packaged.

When packaging, our machine has strict quantity control, which can minimize errors. One particular point to emphasize here is that the drying process is divided into two parts.

Firstly, it is natural drying, which reduces the moisture content of the raw ore from 40% to less than 25%. Then, the raw ore is crushed, and then fluidized dryers are used for further airflow drying.

It has to be said that the commission for dry process is not only simple to operate but also low in cost, and the commission effect is particularly good.

Wet Process: If you want to obtain higher purity organic bentonite, wet purification can meet your requirements .

The process of wet purification is to first crush the raw Bentonite chemical additive to particle size less than 5 mm, add water in proportion to mix, make a slurry, and then stand, so that quartz, feldspar, carbonates and other sandy minerals to settle naturally.

the remaining suspension can continue to use the natural sedimentation method to further settle the sandy minerals,. This method can yield a better quality product.
The disadvantages are long settling time, large floor space and low production efficiency.

In the pulp making process, in order to make the debris minerals block rapid precipitation, can add dispersant to improve the dispersion of clay particles, and then separated.

The concentration of dispersant should not be too concentrated (about 1%), the amount of Bentonite chemical mass of about 0. 5% is appropriate.

After purification for a certain period of time to remove impurities, flocculants are added to the suspension for coagulation and flocculation to achieve solid-liquid separation.

Organophilic clay Bentonite chemical is an organo clay (modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity range organic Inks.

• Exerts gelling efficiency over a wide range of intermediate and low polarity
• Easy dispersing
• The gel is colourless and of high clarity
• Produce reproducible thixotropic consistency over a wide temperature range
• Imparts particle suspension, sag resistance without impairing flow and leveling, preventing hard settling of pigment and fillers
• Exerts strong film reinforcing action in organic binder systems

We recommend that you test the sample to get the final result you need. The most important thing is that we hope to verify whether it matches your formula through the test.
