Embodiment 2

[0072] Weigh the quantitative reagent according to the following formula ratio, phosphoric acid (27.5%), zinc oxide (2.0%), sodium molybdate (0.3%), zinc dihydrogen phosphate (5.5%), potassium chlorate (0.7%), OP-10 (0.2 %), TX-10 (0.2%), SDBS (0.4%), triethanolamine (1.3%), citric acid (1.2%), thiourea (0.15%), deionized water (60.55%). The treatment agent is prepared according to the preparation method of the multifunctional shell surface treatment agent. The shell cleaning operation is carried out by spraying method. The operating conditions are as follows: spraying pressure 0.12MPa, solution temperature 35°C, spraying time 2.5min, ambient temperature 20°C. The test results show that under the above operating conditions, the formula has a rust removal rate of 99.4%, an oil removal rate of 99.0%, and the quality of the phosphating film formed is 1.42g / m2. The phosphating film is uniform and dense, and has good corrosion resistance. The test time is 1.6min. The soaking oper...

Embodiment 3

[0074] Weigh the quantitative reagent according to the following formula ratio, phosphoric acid (30.0%), zinc oxide (2.0%), sodium molybdate (0.5%), zinc dihydrogen phosphate (4.0%), potassium chlorate (0.7%), OP-10 (0.3 %), TX-10 (0.2%), SDBS (0.4%), triethanolamine (1.3%), citric acid (1.2%), thiourea (0.15%), deionized water (59.25%). The treatment agent is prepared according to the preparation method of the multifunctional shell surface treatment agent. Use the spray method to clean the shells. The operating conditions are as follows: spray pressure 0.15MPa, solution temperature 40°C, spray time 3min, ambient temperature 20°C. Under the above operating conditions, the formula has a rust removal rate of 99.6% and an oil removal rate of 98.5%. The quality of the phosphating film formed is 1.37g / m2. The phosphating film is relatively uniform, has slight pores, and has good corrosion resistance. , CuSO4 drop test time is 1.4min. The soaking operation conditions are as follow...

Abstract

The present invention relates to a comprehensive treatment agent, which comprises, by mass, 25.0-30.0% of phosphoric acid, 1.0-3.0% of zinc oxide, 0.1-0.5% of sodium molybdate, 4.0-7.0% of zinc dihydrogen phosphate, 0.3-1.2% of potassium chlorate, 0.3-1.2% of a surfactant, 0.0-2.3% of triethanolamine, 0.8-2.3% of citric acid, 0.1-0.3% of thiourea, and 58.0-62.6% of water. According to the present invention, the treatment agent can be recycled, a treatment cost is low, and pollution on the environment can not be generated.

Description

technical field [0001] The invention relates to the field of treatment agents, in particular to a comprehensive treatment agent and its application method. Background technique [0002] In the surface treatment of shells, the surface treatment of ammunition, mainly degreasing and phosphating, includes degreasing, rust removal, phosphating, and passivation. The oil on the surface of shells is mainly To protect macromolecular substances such as grease, the rust on the surface of the shell is mainly various oxides of iron. The phosphating of the surface of the shell is to cover the surface of the shell with a layer of phosphate to achieve the purpose of anti-corrosion. After phosphating, the surface of the shell needs to be treated Passivation treatment greatly reduces the chemical activity of the active metal or alloy, and becomes a noble metal state, and then undergoes subsequent treatment. The existing technology uses different treatment agents for each different step, resu...
