Aluminium Hydroxide Gel Powder (IP
Grade)
Process
The process consists of the following
steps :-3
Preparation of solution the raw material
:
Solutions of commercial grade soda ash
& Aluminium sulfate desired degree of baume are prepared.
Reaction :
Aluminium sulfate solution is allowed
to react at controlled rate with soda ash at controlled pH
and moderate agitation..
Filtration :
After aging the product, the slurry is
filtered & the wet cake is washed with water till it becomes
free from soluble salt.
Drying & Pulverization :
Product is dried at low temperature to
maintain its structure . Dried lumps are pulverized to get
powder of desired degree of fineness.
Aluminium hydroxide (Gel) I.P. is used
as an antacid and protective in the treatment of peptic ulcers.
It is also used as astringent & antiseptic in cases of
marked hyper acidity. It is used externally as a mild astringent
and desiccant, and internally as an antacid and protective
agent. Aluminium hydroxide is generally used in combination
with other similar chemicals like Magnesium hydroxide &
Magnesium trisilicate in the form of powder or paste, depending
upon the final product i.e. tablet or suspension.
In India, Aluminium hydroxide is
mainly produced in the small sector & there are about
40 players in this market. The aggregate production of all
these units are about 3000 tonnes per year. And the total
estimated demand of the Aluminum hydroxide is about 5000 tonnes.
Export of this chemical is substantial and the project offers
a good opportunities for local producers , as the export market
is flourishing in this segment. Bangladesh, Sri Lanka, Egypt
and Iraq are the largest importers of IP grade Aluminium hydroxide
from India. In the Indian market too, the demand of antacids
raw materials increases by 10 - 15 % every year due to increasing
hyper acidity complaints as well as increase in populations.
Advantages of Indian technologies:
- Low capital investment
- High employment potential
- Maximum use of local raw materials
and manpower resources
- Adaptable levels of sophistication
