Using vaporized solid formaldehyde
Thread Content
During the production of polyformaldehyde, the formalin solution in an evaporator polymerizes into solid formalin. The evaporator is heated using a jacket; yesterday, the melting point of this solid formalin was measured to be 123 degrees. We are considering using 3S steam to melt it – is this approach feasible? Please discuss it.
Dude, what kind of steam is “3S steam”? Haven’t heard of it? However, based on the information provided by the poster, if the melting point of this solid formaldehyde is 123 degrees, it should be feasible to use low-pressure steam heating at 0.25~0.3 MPa (A), with a steam temperature of 130~140°C.
