Bentonite powder is a natural clay material proven to be a great absorbency material. The ability of the bentonite powder to absorb liquids, oils and even some dissolved impurities is due to its high surface area, high cation exchange capacity and swelling property. Hebei Hezhen Industrial Co., Ltd. specializes in processing, crushing and selling the non metallic mineral bentonite powder.
The Unique Structure of Bentonite
The special structure is directly related to the absorbing capacity of the bentonite powder. The most prevalent, and most desirable, form of Bentonite is a predominately Aluminum Phyllosilicate, whose layers are very thin – just 1 nanometer thick. When liquid molecules are allowed to enter the interlayer space between the different stacks of layers, the space can be large between the individual layers. These layers have a small volume when dry, but open up into a large volume when in contact with liquids. The possibilities of absorption/adsorption sites are seemingly endless with up to and over 700 square meters of surface area for one gram of high quality bentonite. Hebei Hezhen Industrial Co., Ltd. bentonite powder adopts special process to ensure that the swelling property will not affect the particle's size, which is convenient for use in industry.
High Liquid Absorption Capacity
The best part of the bentonite powder is its excellent absorption of liquids, absorbing several times its own weight. Absorption is possible for water, oils and other polar liquids, the process involves surface adsorption and incorporation into interlayers, and sometimes gelation. Bentonite forms a thixotropic gel when it comes in contact with water, and it is this gel that "traps" the excess water. It reduces oils and other chemical liquids to semi-solid waste, which are easily collected and disposed. The absorption capacity of bentonite powder, however, and the amount of material that is reduced per unit oil absorbed is considerably less than for many other oil absorbent materials. Hebei Hezhen Industrial Co., Ltd. is able to ensure the absorbing ability of each batch of bentonite powder by adopting the general quality control system.
Cation Exchange and Contaminant Removal
The Bentonite also can absorb impurities dissolved in water through cation exchange. The charge over the montmorillonite layer is always negative and thus, cations such as sodium, calcium, magnesium etc. are always present in the interlayer space of the clay. These cations can be exchanged with positively charged impurities such as contaminant cations that are removed from the solution and incorporated into the structure of the clay. This provides a very low cost and readily available treatment for wastewater, such as heavy metals. Acid mine drainage, lead, copper and zinc removal are just a few examples where the ability of bentonite to remove cations is beneficial. Bentonite is not only inexpensive but also very efficient and effective in purification of the waste products and in treating of the polluted environments. Hebei Hezhen Industrial Co., Ltd. offers batches with a well-controlled cation exchange capacity to guarantee to customers the most suitable products.
Application in Oil and Grease Absorption
A frequent occurrence in the industrial environment are oil and grease spills and they can be a nuisance and hazard. Bentonite powder has proven itself to be effective at absorbing petroleum products and oils. In fact, some of the surface modified grades will even absorb hydrocarbon liquids very well. Being able to pour bentonite powder on an oil slick, let it work and then sweep it up to the workshop floor or for an oil slick on a maintenance site is very useful. This clay has the capacity to absorb oil and grease at the molecular level, more so than a lesser permeable absorbent and this oil cannot be easily removed from the clay by a mechanical force. Hebei Hezhen Industrial Co., Ltd is a manufacturer of such bentonite powder which is a particular kind of bentonite powder designed as an industrial absorbent. Since 2003 its main factory is dedicated to this type of processing and has been perfected over the last few years.
Performance in Pet Litter and Animal Bedding
The use of bentonite powder is perhaps most widely known as cat litter. It can trap a lot of liquids within itself which is many times its own weight; it also has the advantage of trapping many odoriferous compounds within its structure. When cat litter comes in contact with liquids, it will clump. This has been developed into a successful absorption system, but only part of the material has been removed - just the clumps. Large-scale animal treatment facilities (e.g. kennels, vet practices, farmyards) will greatly benefit from the use of such material as its highly absorbent properties are cost effective compared to the vast quantities of less efficient absorbents that may be needed. The simple characteristics of bentonite make it ideal for binding ammonia compounds, and can be processed a little to bind a larger spectrum of offensive odor producing molecules. Hebei Hezhen Industrial Co., Ltd. bentonite powder is specially designed for cat litter products and can control the consistency of particle size.
Conclusion
Bentonite powder is extremely effective for absorption applications because of its superior structural makeup, large surface area and high absorption potential, as well as the cation exchange property that means it can also effectively absorb dissolved contaminants. From the time of large oil and chemical spills being absorbed, to using it for treating waste products, to even using it for cat litter, it's a readily available, low cost alternative that can be effective for most uses.
