Glass-lined and stainless steel reactor with the capacity 50-30000l. Corrosion resistance stability: very high corrosion resistance against inorganic acid, organic acid, organic solvent with different concentration and weak base, but not applicable to alkali, hydrofluoric acid, fluoride-bearing medium and phosphoric acid with concentration above 30% at temperature over 180. Resistance to impact: 220-10-3j. Thermal shock resistance: resistance to sudden cooling 110, resistance to sudden heating 120. Insulation performance: the enamel surface should be strictly tested at 20kv.
