The quality control of salt is the key to the operation and management of sodium hy-pochlorite generators.Production test of the generator using different qualities of salt,the results show that,when the total amount of calcium and magnesium ions in the salt is less than 30 mg/kg,and the sulfate ion content of the salt is less than 2 000 mg/kg,it can significantly alleviate the e-lectrode scaling,reduce the effective chloride consumption,power consumption and equipment loss of the generator,and avoid the precious metal coating in the electrode being damaged by frequent pickling,while other impurities have no obvious adverse impact on the operation of the generator e-quipment and product quality.Therefore,the uniodized salt that meets the requirements of calci-um,magnesium and sulfate as the raw material of the generator has the highest comprehensive benefit.
