activated bleaching earth

Physical & Chemical Characteristics A kind of hypo-white powder, which is odorless, tasteless and non-poisonous, the product ha

Applications & Rang of Use

1.      In refinement of animal & vegetable oils, used for decolorization and purification to eliminate harmful pigments, flavacol, phospholipid, saponin, gelatine, and cotton acid etc. in the oil, rendering it into top-grade cooking oil.

2.      For decolorization & refinement of industry-used animal & vegetable oils.

3.      In petroleum industry, used for decolorization, refinement and purification of petroleum, grease paraffin, white oil, lubricating oil, Vaseline, and kerosene etc.

4.      For recycling and regeneration of industrial waste oils (including mineral oil, such as machinery oil and lubricating oil etc.)

5.      For decolorization & depuration of resin.

6.      For decolorization & depuration of polyether.

7.      In food industry, used as clarificant for monosodium glutamate vitamin, grape wine, candy juicy, used for stabilizing treatment of beer, and used for purification of sugar juices.

8.      For alkene separation in arene and alkane, cracking of petroleum and alkene polymerization catalyzed.

 

Packing, Storage, Transport and Precautions

1.      The internal bag is polythene film bag while the external bag is polypropylene plastic woven bag; or the internal bag is polythene film bag white the external bag is composite paper bag. Each bag has a net weight of 25kg. The packing can be customized to the customers needs.

2.      Store in a ventilated and dry place. Employ a clean carrying vehicle for transportation; every effort should be made to avoid drastic shock; leisurely handling is recommended in loading & unloading to prevent any damage on the container bag. Guard against moisture and never expose the product to rains.

3.      Due to its strong water absorption, the product can have its performance lowered by influence from dampness.

Two important conditions of guaranteeing the quality:

1.      Raw Material :

Choosing the good quality bentonite excavated from the area of about 100 meters deep from the earths surface, its purity is higher than that from the earths surface; Activated reacting with high quality concentrated sulphuric acid with the bentonite. It is the base of good quality of Activated Clay.

2.    Drying Technology

At first, Coal hot air furnace produces the high temperature flue gas. The heat energy is exchanged through the calandria of heat exchanger and getting the hot air. Then the hot air is guided into the desiccator to dry the bleaching earth. The High temperature flue gas is exhausted from smoke funnel after exchanging the heat with the . The purity of bleaching earth is higher by the above way of drying, comparing with drying with the high temperature flue gas entering the desiccator directly.
