What is the pH of lithium bromide water solution?
Lithium bromide has a strong corrosion effect on steel in the air, but adds a corrosion agent in a vacuum state, which basically does not corrode the metal. \u0026 nbsp; \u0026 nbsp; lithium bromide (libr) solution is a strong corrosive medium, weak alkaline, and has strong corrosiveness for ordinary metal materials, such as carbon steel and copper. Test studies have shown that the main factors affecting corrosion are as follows. \u0026 nbsp; \u0026 nbsp; oxygen. In contact with oxygen, the corrosion is particularly serious. Such as the upper part of the absorber and the evaporator's water disk, etc., splashing lithium bromide solution during the runtime of the machine, forming a very rare liquid film, which is susceptible to oxygen invasion, and the corrosion is serious. Due to the filling solution in the generator, there is less chance of contacting oxygen, and corrosion is light. Therefore, oxygen is an important factor in accelerating corrosion. \u0026 nbsp; \u0026 nbsp; The concentration and temperature of the solution. Under normal pressure, with the decrease in the concentration of lithium bromide solution, corrosion has intensified, because the solubility of oxygen in the dilute solution is larger than the thick solution; the content of oxygen in the low pressure under low pressure is very low. Therefore Small. The test also shows the relationship between temperature and corrosion; in the solution that does not contain a corrosion agent, the corrosion rate of A3 steel and copper increases with the increase in temperature; the solution with lithium chromate composite doses, A3 A3, A3 A3 The corrosion rate of steel has decreased slightly as the temperature rises. \u0026 nbsp; \u0026 nbsp; The pH value of the solution. The test shows that when the pH value of lithium bromide solution is 8.0 ~ 10.2, as the pH value rises, the corrosion rate of steel is slightly reduced, and the bronze has increased slightly. Practice shows that the pH value is more appropriate at 9.5 ~ 10.3. \u0026 nbsp; \u0026 nbsp; 4. The corrosion agent. A large number of experimental research and operation practice shows that adding SB2O3, CRO4, PBO, AS2O3 and other compounds to lithium bromide solution can effectively inhibit the corrosion of ordinary metal materials for lithium bromide solution. Tests also show that lithium chromate is a good corrosion agent. Because it can form a protective film on the metal surface, it effectively suppresses the occurrence of corrosion. \u0026 nbsp; \u0026 nbsp; test proves that the corrosion rates of A3 steel and copper are reduced with lithium chromate concentration, because the greater the lithium chromate concentration, the better. After testing, the concentration of lithium chromate in the solution is good when the concentration of chromium is 0.1%to 0.3%.

The lithium bromide solution is weak and acidic, because this is a strong acid and weak alkali salt; but the acidity is not very strong, but it can absorb alkaline ammonia.
The reason for the lithium bromide corrosion is due to the existence of bromine ions. The corrosion mechanism of bromine ion has the same corrosion mechanism as chloride, but the corrosion should be a little weaker than chlorine.Oxygen and weak acidity, the corrosion effect is very obvious.
