Praseodymium reacts with mineralizer, and is transported in vaporstate to the reaction site of zircon.
镨也是与矿化剂反应后,以气态迁移到锆石反应位置的。

Cleaning of the surface is in the form of bubble formation on the part that vaporizes the chemical in order to react the oxidizer in the vaporstate to the exposed surface at the bubble growth area.
Separation of water and gas is reliable (water vapor enters from bottom of valve by the U general type), remain the state of water sealing in the valve, effectively prevent leakage of steam.
