Embodiment 1
[0020] The mass percent of each component of sodium percarbonate anti-caking agent is:
[0021] 70% Dispersant: 45% maleic acid-acrylic acid copolymer, 25% sodium polyacrylate;
[0022] 25% penetrant: 15% sodium alkylbenzene sulfonate, 10% fatty alcohol polyoxyethylene ether;
[0023] 5% Hydrophobic agent: sodium stearate.
[0024] After preparing each component according to the above ratio, mix them evenly to obtain the anti-caking agent. Add the anti-caking agent according to 0.5% of the total mass of sodium percarbonate. The specific addition method is: dissolve the above-mentioned anti-caking agent in water to make a solution, and apply the anti-caking agent solution evenly on the overcoating surface through a fluidized bed spraying device. The surface of the sodium carbonate particles is used to obtain anti-caking sodium percarbonate. In addition, after pulverizing the anti-caking agent of the above proportion to make a powder, it is uniformly mixed with the sodium per...
Embodiment 2
[0027] The mass percent of each component of sodium percarbonate anti-caking agent is:
[0028] 60% Dispersant: maleic acid-acrylic acid copolymer;
[0029] 35% penetrant: 15% sodium alkylbenzene sulfonate, 10% sodium secondary alkyl sulfonate, 10% fatty alcohol polyoxyethylene ether;
[0030] 5% Hydrophobic agent: sodium stearate.
[0031] After preparing each component according to the above ratio, mix them evenly to obtain the anti-caking agent. Add anti-caking agent by 0.05% of the total mass of sodium percarbonate, and other operations are the same as example 1.
[0032] Gained anti-caking sodium percarbonate is packaged in a ton bag, and the product has no caking after being stored in a compressed bag for 6 months.
Embodiment 3
[0034] The mass percent of each component of sodium percarbonate anti-caking agent is:
[0035] 60% Dispersant: maleic acid-acrylic acid copolymer;
[0036] 35% penetrant: sodium secondary alkyl sulfonate;
[0037] 5% Hydrophobic agent: sodium stearate.
[0038] After preparing each component according to the above ratio, mix them evenly to obtain the anti-caking agent. Add anti-caking agent by 0.2% of the total mass of sodium percarbonate, and other operations are the same as example 1. Gained anti-caking sodium percarbonate is packaged in a ton bag, and the product has no caking after being stored in a compressed bag for 6 months.
