How to reduce iron powder replacement consumption

 The advantage of reduced iron powder in replacement

Due to its high content of metal iron MFe and low impurity content, its contact surface (more than surface) is large, which is very suitable for copper substitution and precious metal replacement.
Used for replacement of iron powder is the most effective ingredients of elemental iron, the content is determined by the replacement of the same quantity of iron powder product demand, mainly through the following aspects in the production of replacement to how to reduce the consumption of iron powder:

1. Requirements for iron particle size

The use of 60-150 is usually used to reduce the consumption of iron powder in the displacement reaction, while at the same time, the speed of reaction can be fast and the yield is ensured.

2.Requirements for iron content

The iron content of iron powder directly affects the substitution of iron powder consumption, high content of iron MFe iron powder, less dosage, low impurity content and at the same time, the quality of the products for replacement with good results.
The low iron content of the single iron is the opposite.
Due to the economic considerations, the total iron (TFe) content is 95% and the content of MFe is about 93%.

3.The effect of the PH of the solution on the iron powder

The PH value of the control solution can be reduced.
As the solution PH is reduced, switching speed, as to the displacement of metal particles in the solution is reduced, with exchange rate is slow, and finally reach the dissolution and precipitation, the balance has remained to run out of iron powder.
