Glass-lined reactor

The glass-lined reactor is made of glass containing high silica, which is firmly bonded to the inner surface of the metal equipment after high temperature firing. It has the advantages of glass stability and high strength of the metal itself, corrosion resistance, smoothness, wear resistance and certain stability. It has been widely used in chemical, pesticide, pharmaceutical, dye, food and metallurgical industries. The performance of the glass-lined reactor is as follows.

①Corrosion resistance It is resistant to various concentrations of inorganic acids, organic acids, organic solvents and weak alkalis, but it is not resistant to hydrofluoric acid and fluoride ion-containing media, concentrated phosphoric acid and strong alkalis with a temperature greater than 180°C.

②The heat resistance is allowed to be used within the range of 30 to 240°C, the heat-resistant temperature difference is less than 120°C, and the cold-resistant temperature difference is less than 110°C.

③Impact resistance The impact resistance is poor, so avoid the impact of hard objects when using it. Glass-lined equipment should not be used for storage and reaction of the following media, otherwise it will be quickly damaged due to corrosion:

①Hydrofluoric acid of any concentration and temperature;

② Alkaline medium with pH value> 12 and temperature greater than 100°C;

③ Phosphoric acid with a temperature greater than 180°C and a concentration greater than 30%;

④The reaction process of alternating acid and alkali;

⑤Other media containing fluoride ions.

The glass-lined reactor should be protected from collision during transportation and installation. Strictly prevent heavy objects from falling into the container when feeding, and slowly pressurize and heat up during use to prevent drastic changes.
