Rockdefoam 8050 is a very efficient defoamer which can be safely used in production process of phosphate based fertilizers.
|pH (1:10 solution)||7 ± 0.5|
|Cloud Point||≤ 10°C|
|Solubility||Dilution with 50% water does not exhibit any gel formation.|
|Pump ability||Pump ability: Due to Non-Gelling/NonThickening behavior even at 0°C, does not pose any problem in pumping or choking of pipe lines|
When nitric acid is added to the phosphate rock, the digester has a temperature of about 60°C and the acid strength is 60%. At the evaporation stage the temperature is 180°C.
Rockdefoam 8050 has proved to be very powerful defoamer in the manufacture of complex fertilizers produced from the following important rock phosphates:
Kola Phosphate, USSR, Morocco
Phosphate, Florida Phosphate, Granges
Phosphate, Sweden, Jordanian Phosphate
Usually, foam is caused by carbonates in the
appetites out of five different rock
phosphates mentioned above. Florida
phosphate and Morocco phosphate cause
great foam problems. Quantities of
Rockdefoam 8050 used in these two varieties vary between 0.05 to 0.1% on the weight of rock, i.e. 500 grams to 1 kg of Rockdefoam 8050 for 1 ton of rock is sufficient to suppress foam. However, this quantity may change depending upon conditions during operation.
Foaming caused due to various reasons mentioned above can easily be suppressed by dosing 0.005 to 0.05% of Rockdefoam 8050 on Pump ability: Due to
Rockdefoam 8050 defoamer exhibits the following outstanding characteristics in actual plant usage:
1. Lowers the surface and interfacial tension.
2. Significantly lowers defoamer cost per ton of acid produced.
3. Promote more complete reaction.
4. Does not affect rubber tank and hose lining.
5. Does not discolor or clog filter cloth.
6. Improves filtration and crystallization.
