The allophane (Allophane), are made of low amorphous or crystallinity hydrated aluminum silicate, the amorphous clay quasi minerals that of, was discovered in Germany in 1816.
Volcanic glass and feldspar in the volcanic ash soil layer is the material that was altered by long-term weathering or hydrothermal.
Allophane of Japan, of the surface layer of the part even in the volcanic ash soil andosol contains many (1 million years ago-formation age of over the current).
Our products of raw materials Allophane is 100% domestically produced is, Gunma Prefecture Akagi in the volcanic ash soil layer of, Tochigi Prefecture Mooka production will be of.
The structure sheet aluminum (alumina) and silicon (silica) made up of a layer of size 3.5 ~ 5.0 nm hollow sphere is approximately 10 fine for adsorption for one sphere it is a porous material that hole is present.
Even when compared with other adsorbents vast surface area has a (400 to 900 square meters / 1g).
Silica gel substantially equal hygroscopicity ( adsorption and drying agents with reference) typical activated carbon or more deodorant and adsorption performance ( deodorant and desiccant combines reference), is a very excellent material as an adsorbent.
The high ion exchange capacity and organic acid adsorption capacity for having a variety of organic acids (phosphoric acid, etc.), bases, moisture, and has the capability to adsorb radioactive cesium, holds.
pH is weakly acidic to neutral (5-7), there are buffering action against pH changes strong acidification is also characterized.
Odorless, harmless and, heat (useful temperature is recommended 400 ℃ or less, high also does not is firing at a temperature) strongly, deodorants and industrial adsorbent for ozone decomposing agent-cleaning solvent management and research laboratory and cosmetics and pharmaceuticals, and it is your patronage in the industry in a variety of fields.
- Dehumidification and odor components of the adsorption (deodorizing) effect, organic matter adsorption, there is a decomposition capability etc ... of ozone.
- Binder was molded without using a (binder), the product having excellent water resistance and strength.
- By blending activated carbon by purpose or use, further moldings with improved performance.
- Though chemically stable, it does not cause decomposition or degradation in many months.
- Gas phase, can be used in both of the liquid phase.
