A set of sorbents were selfmade to remove alkali vapor in high temperature. Compared with some natural mineral sorbents, GM6 was proved to be the best sorbent with the highest sodium content.
the corrosion mechanism is that:(1)SiAlON reacts with alkali vapor generating kaliophilite and reacts with slag generating ferric olivine,and promote the forming of silicate glass phase;
To introduce the harm of acid and alkaline steam dispersing to human and environment in steel wire products producing The principle and technology reform methods,such as ventilation,covering,restraining,absorption and adsorption are expounded Several typical examples of harnessing at home are given
Results of XRD and the kinetics indicated that adsorption process of GM6 was physical adsorption in nitrogen atmosphere and it was controlled by diffusion of a sodium resultant layer, adsorption process of GM6 was chemical adsorption in nitrogen and water vapor atmosphere and it was controlled by both chemical reaction and diffusion of a sodium resultant layer.
After the irradiation is complete, the surface contacting with the alkali vapor is again saturated with the alkali atoms with a time constant of about 1 h.
We calculate the requirement of wall coatings designed to minimize the interaction of an alkali vapor with the wall and explain how this affects trapping efficiency.

It is analyzaed that the corrosion process for the regenerator checker of the float glass furnace by dint of the scanning electron microscope in this text. The aluminosilicate system brick and AZS checker are primarily etched by the ruining gas comprising Na, SO 2 and Na 2SO 4 etc. In this case, it is important cause for checker cracking that expanding effect of the nepheline and nosean produced by the phase transformation. The checkers made from the periclase as main crystal phase are cracked owing to h...
A set of sorbents were selfmade to remove alkali vapor in high temperature. Compared with some natural mineral sorbents, GM6 was proved to be the best sorbent with the highest sodium content. Results showed that sodium content was dependent on chemical constituent and microporous structure of sorbent. Results of XRD and the kinetics indicated that adsorption process of GM6 was physical adsorption in nitrogen atmosphere and it was controlled by diffusion of a sodium resultant layer, adsorption process of GM...
