Glass lined reactor has good corrosion resistance, so it is often used in chemical industry and other industries. However, not all media can be used. We should also pay attention to its scope of use, so as to better ensure the use effect.
(1) Hydrofluoric acid and fluoride ion medium.
(2) Phosphoric acid, concentration above 30%, temperature above 180 ° C.
(3) Sulfuric acid, concentration 10% ~ 30%, temperature higher than 200 ° C.
(4) Alkali liquor, pH ≥ 12, temperature higher than 100 ° C.
When using the glass lined reactor, the medium should be known in advance to ensure that it can be used within its normal range.
