Embodiment 1

[0020] The powder composition for metal surface cleaning is prepared from the following compounds in parts by weight: 10-20 parts of sodium carbonate, 10-20 parts of potassium bicarbonate, 15-30 parts of oxalic acid, 5-10 parts of citric acid, 10~15 parts of polymaleic acid, 50~60 parts of carboxymethyl cellulose, 30~40 parts of silicon dioxide. Add carboxymethyl cellulose and silicon dioxide into the mixing tank, then add sodium dodecylbenzenesulfonate twice the weight of the mixture and ethanol five times the volume of the mixture, heat and stir for 1 hour, then add sodium carbonate, carbonic acid Potassium hydrogen, oxalic acid, citric acid and polymaleic acid were stirred evenly, and the product was obtained by rotary evaporation at 45°C until the weight was constant.

[0021]

Embodiment 2

[0023] The powder composition for metal surface cleaning consists of the following compounds in parts by weight: 15 parts of sodium carbonate, 15 parts of potassium bicarbonate, 20 parts of oxalic acid, 5 parts of citric acid, 15 parts of polymaleic acid, carboxymethyl 60 parts of cellulose, 30 parts of silicon dioxide. Add carboxymethyl cellulose and silicon dioxide into the mixing tank, then add sodium dodecylbenzenesulfonate 3 times the weight of the mixture and ethanol 8 times the volume of the mixture, heat and stir for 1.5 hours, then add sodium carbonate, carbonic acid Potassium hydrogen, oxalic acid, citric acid and polymaleic acid were stirred evenly; the product was obtained by rotary evaporation at 42°C until the weight was constant.

[0024]

Embodiment 3

[0026] A powdery composition for metal surface cleaning, prepared from the following compounds in parts by weight: 15 parts of sodium carbonate, 15 parts of potassium bicarbonate, 20 parts of oxalic acid, 20 parts of polymaleic citrate, carboxymethyl 55 parts of cellulose, 35 parts of silicon dioxide. Add carboxymethyl cellulose and silicon dioxide into the mixing tank, then add sodium dodecylbenzenesulfonate twice the weight of the mixture and ethanol five times the volume of the mixture, heat and stir for 1 hour, then add sodium carbonate, carbonic acid Potassium hydrogen, oxalic acid, and polymaleic acid citrate were stirred evenly, and the product was obtained by rotary evaporation at 45°C until the weight was constant.

Abstract

The invention relates to a powdery composition for cleaning a metal surface and a preparation method thereof. The powdery composition is prepared from the following chemical compounds in parts by weight: 10-20 parts of sodium carbonate, 10-20 parts of potassium bicarbonate, 15-30 parts of oxalic acids, 5-10 parts of citric acids, 10-15 parts of polymaleic acids, 50-60 parts of carboxymethyl cellulose, and 30-40 parts of silicon dioxide. The powdery composition provided by the invention has low residual quantity on the metal surface, the cleaning effect is good, the original nature of the powdery composition can be recovered through simple treatment, and the cleaning cost is reduced. The polymaleic acids and the citric acid ester are originally used for the wrinkle resistant treatment of clothing, and the polymaleic acids, the citric acid ester, the sodium carbonate, the potassium bicarbonate and the oxalic acids are mixed for use, so that the stain removal effect on the metal surface can be improved; moreover, the polymaleic acids and the citric acid ester can be used as addition agents for increasing the recovery rate of powder in the process of recovering the original nature.

Description

[0001] technical field [0002] The invention belongs to the technical field of cleaning metal materials, and in particular relates to a powder composition for cleaning metal surfaces and a preparation method thereof. [0003] Background technique [0004] Affected by factors such as traditional thinking concepts and lack of cleaning technology resources, most enterprises and individuals still remain in the traditional "destructive" processes such as machinery, high-pressure water, and chemical pickling for the impact and removal process of metal equipment scaling. And concepts; and simply think that metal cleaning will only be considered in the case of seriously affecting production. It does not know that the generation of scale is constantly affecting the energy consumption of enterprises and devouring profits of enterprises. Moreover, in order to reduce the cost of cleaning alone, a cleaning method that damages and corrodes the equipment is chosen, resulting in the leaka...
