Embodiment 1
[0015] The amount of each component of the stabilizer used to prepare phosphorus-free sodium percarbonate is: 2.0kg silicate, 2.0kg copolymer of carboxylic acid and sulfonate, 2.0kg inorganic magnesium salt, 3.0kg sodium polyacrylate, organic alcohol amine 1.0kg, disodium edetate 0.35kg.
[0016] Add silicate, carboxylic acid and sulfonate copolymer, inorganic magnesium salt into 280kg sodium carbonate, stir until all dissolve.
[0017] Add sodium polyacrylate, organic alcohol amine, and disodium edetate into 350 kg of hydrogen peroxide, and stir until they are completely dissolved.
[0018] Sodium carbonate and hydrogen peroxide that will be added with stabilizing agent are mixed, input in the reaction kettle of belt stirrer and cooling jacket, carry out crystallization production sodium percarbonate product according to the common process in the prior art.
[0019] Contrast test: use raw material sodium carbonate, hydrogen peroxide of same weight, traditional stabilizer con...
