Acid - base standard for glass - lined reactor
Acid and alkali resistance standard: the acid and alkali degree standard of glass lining reaction kettle is often used in chemical industry, petroleum, printing and dyeing and other industrial fields. Most enamel reactions are carried out under the condition of acid and alkali, so the glass lining equipment must have a good ability to withstand acid and alkali.
Glass lined reactor equipment for a variety of concentrations of inorganic acids, organic acids, organic solvents and weak base and other media have a strong corrosion resistance.
But for the strong alkali, hydrofluoric acid and fluoride ion medium, and a temperature greater than 180 ℃, the concentration is greater than 30% of phosphoric acid and so on do not apply.
Standard heat resistance change: the use of enamel reactor temperature is usually in the range of 0 ~ 200 ℃, if the temperature change is bigger, also must be done slowly.
