As a kind of chemical equipment, glass-lined reactor is often in contact with some chemical products, so its corrosion resistance is very good. However, in order to better avoid equipment corrosion, still need to take some anti-corrosion measures. The following mini-series will show you how to prevent reactor corrosion.
1. Glass-lined reactor should always be used to clean the surface of equipment with clean water, in order to slow down the occurrence of corrosion. But this is not a good solution. Although the equipment is protected, it can cause water pollution. It is recommended that the user coat the external surface of the equipment with a resin anticorrosive coating after installation to protect the equipment from the beginning. If the external surface of the equipment needs heat insulation treatment, should also be coated with a layer of anti-corrosion coating.
2. The glass lining is a layer of glass pre-sintered in a metal kettle to resist chemical corrosion. Please note that glass lining can not be used for alkaline materials as the glass will be dissolved and corroded by alkali and both acids and bases of the glass lining reactor can be used.
3. Heating the glass lined reactor, there will be some corrosion. When the heating temperature is below 100 ° C, the steam below atmospheric pressure can be used for heating. In the range of 100 ~ 180 ° C, full steam can be used. At higher temperatures, high-pressure superheated steam can be used, which to some extent reduces corrosion.
Therefore, if you want to avoid the glass lined reactor corrosion or improve the anti-corrosion performance of reactor equipment, may wish to follow the method for treatment to better avoid the corrosion of equipment. At the same time, regular maintenance of equipment can also effectively avoid the possibility of equipment corrosion.
