Bentonite Clay Powder Supplier & Manufacturer in China

The final quality and performance of bentonite Clay Powder are directly related to its production process, the degree of its technological, and the strength of the composition and structure of the raw bentonite ore.

In our production process of over 20 years, we have found that we must choose an appropriate purification method based on the characteristics of the bentonite raw ore.

Because there are many new influencing factors proposed by the technical team, such as the speed and time of centrifuges, the type and dosage of dispersants added, and the temperature of bentonite, all of which will affect the final product quality.

So the surface modification of  Bentonite Clay Powder refers to the physical, chemical, mechanical and other methods used to treat the surface of organic bentonite.

We will treat the surface of different organobentonite models based on their final application direction, whether it is for their physical or chemical properties,

In order to ultimately achieve the dual advantages of the performance and use value of bentonite clay .

So, in order to fully realize the performance of organic bentonite, we have also carried out dry process and wet activation of bentonite, And pre gel activation.

The method is to directly mix the ground-based bentonite with the covering agent, which has a water content of about 20%.

and then add the mixture evenly before squeezing to make an organoclays bentonite with a certain amount of water, and then dry, crush and grind it to make a powder product.

Sometimes we also add organophilic clay bentonite with a certain amount of water, and directly put it into an organic solvent to make a domain gel or emusision product.

The biggest difference is that when we wet process treatment, we disperse sodium based Bentonite Clay Powder, then make a slurry, purify it, and then carry out activation modification treatment.

After a series of treatments, we transformed it into a hydrophobic organic complex, which was then dehydrated, dried, crushed, ground, and ultimately transformed into a powdery structure of organic bentonite.

And the preparation method of operating Bentonite Powder we just mentioned is actually very similar to wet process treatment, because we need to disperse bentonite, then make a slurry.

and then add organic solvents, such as some base oil mineral oils, to the organic bentonite process after purification and modification.

These can be done, and then extract the hydrophobic organic bentonite complex into the organic solvent, and evaporate it, The residual water is directly made into organobentonite pre gel.

To put it more generally, the quality of raw ore bentonite and montmorillonite of different quality is very different from that of the final organic bentonite.

Montmorillonite can exchange metal cations, and the ion exchange capacity directly affects the quality of organic bentonite.

Therefore, the bentonite needs to be activated before the organic activation. This is the preparation process of organic bentonite that we briefly introduce.

It also allows you to have a better understanding of our process of producing organic bentonite about how do we control our quality?

Finally, we have to mention that most of the organic bentonite produced in China is chemically modified from calcium-based bentonite and then subjected to organic activation, which will result in better quality.

Organophilic clay 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.
