Selection of foam liquid for ship foam tank

The selection of foam solution for ship foam tank is a very important process, which directly affects the effect of foam extinguishing. When selecting foam concentrate, the following aspects should be considered:

1. Fire type: different types of foam liquid are required for different types of fires. For example, for oil fires, foam liquid that can quickly cover the oil surface and prevent the spread of oil fires should be selected. For solid material fire, foam liquid that can penetrate into the solid and reduce the combustion temperature shall be selected.

2. Environmental conditions: environmental conditions will also affect the selection of foam concentrate. For example, high temperature environment may require the use of foam solution that can withstand high temperature, while low temperature environment may require the use of foam solution that can work stably at low temperature.

3. Equipment performance: the model and performance of the ship's foam tank will also affect the selection of foam concentrate. For example, some foam tanks may need to use high viscosity foam concentrate, while others may need to use low viscosity foam concentrate.

4. Environmental requirements: With the improvement of environmental awareness, more and more ships begin to use environmentally friendly foam liquid. These foam liquid can not only extinguish the fire, but also reduce the pollution to the environment.
