Product Name: bleaching powder/fullers earth/bentonite clay for oil refining
It is used high purity montmorillonite as main raw material, through activation treatment by inorganic acid, we get efficient adsorbent after rinsing, drying and grinding.
This product was gray, pink or blue gray powder, no mechanical impurities, it's available for grease (refining decolorization of animal or vegetable oil ), pharmaceutical and winemaker related food industries. The quality of our products are better than national standards, stable performance, strong bleaching power(less add at ton unit ), high filtration speed.
main performance index:
surface area (m²/g) | Activity degree (m.mol/kg) | decolorization ratio (%) | water (%) | particle (-200M%) | free acid (H2SO4) % | Bulk density (g/ml) |
≥170 | ≥180 | ≥90 | ≤10 | ≥90 | ≤0.2 | ≤0.8 |
Note:It is used in decolouration of cooking oil. Packing 25K/gplastic bag, customized |
