The melting point of yellow phosphorus is 44.1℃, the ignition point is 35℃, and the density of liquid yellow phosphorus is 1.72g / cm³ at 70℃. Yellow phosphorus has active chemical properties and burns when it comes into contact with air. It is a self-igniting item among hazardous chemicals. Yellow phosphorus can cause serious burns when it comes into contact with the skin. There are high safety risks during production, storage, transportation and use. Yellow phosphorus settles at the bottom of the container when stored, and there is generally a mud phosphorus layer and a sealed water layer on the upper part. When transporting, a submersible pump is inserted into the bottom of the container to extract yellow phosphorus. If the container is relatively large, the cantilever of the submersible pump is relatively long, the erection time is long, and the maintenance efficiency is low.
