Embodiment 1
[0052] The present embodiment provides a kind of processing method of regulating and controlling the color treatment liquid of the rust layer on the surface of weathering steel, such as figure 1 As shown, the processing method includes the following steps:
[0053] 1) Surface cleaning of weathering steel: remove the scale on the surface of weathering steel by shot blasting or pickling, cut into 40mm×40mm weathering steel sheets, degrease with acetone, grind the experimental weathering steel to 600# with sandpaper, and finally use Clean with absolute ethanol and blow dry;
[0054] 2) Preparation of weather-resistant steel surface rust layer color treatment solution: the treatment solution includes a precursor solution and a corresponding stabilizing solution, and 500 g is prepared respectively according to their respective mass fractions to obtain a precursor solution and a corresponding stabilizing solution with uniform solute;
[0055] 3) Corrosion and coloring of weathering...
Embodiment 2
[0064] The processing method of this embodiment is basically the same as that of Embodiment 1, except that:
[0065] The precursor liquid is liquid B, and the corresponding stable liquid is liquid b.
[0066] The mass fraction of each component in the precursor liquid B is: 0.5% to 3.5% NaCl, 0.1% to 2% FeSO 4 , 0.1%~1%CuSO 4 , 0.1%~2%NaHSO 3 , and the balance is water.
[0067] The mass fraction of each component in the stable solution b is: 0.8% to 2% NaCl, 0.3% to 1.5% FeSO 4 , 0.2%~0.8%CuSO 4 ,0.1%~0.3%NaNO 3 , and the balance is water.
[0068] Adding mass fraction range of 40% absolute ethanol to the precursor liquid B liquid to replace the same mass fraction of water in the precursor liquid B liquid, and then spraying the surface of the weathering steel to promote rusting of the weathering steel surface. Layers dry quickly.
[0069] Adding anhydrous ethanol with a mass fraction range of 1% to the stabilizing liquid b to replace water of the same mass fraction in...
Embodiment 3
[0072] The processing method of this embodiment is basically the same as that of Embodiment 1, except that:
[0073] The precursor liquid is liquid C, and the corresponding stable liquid is liquid c.
[0074] The mass fractions of the components of the C liquid include: 0.1% to 2% NaCl, 0.5% to 0.9% NaCl 2 SO 4 , 0.6%~1%CuSO 4 ,0.2%~2%FeSO 4 , 40% absolute ethanol, and the balance is water.
[0075] The components and mass fractions of the corresponding stable liquid c include: 0.5% to 2% NaCl, 0.2% to 0.8% Na 2 SO 4 , 0.4% ~ 0.8% CuSO 4 ,0.5%~1.5%FeSO 4 , 0.1%~0.2%NaH 2 PO 3 , and the balance is water.
[0076] Adding mass fraction range of 40% absolute ethanol to the precursor liquid C liquid to replace the same mass fraction of water in the precursor liquid B liquid, and then spraying the surface of the weathering steel to promote rusting of the weathering steel surface. Layers dry quickly.
[0077] The color of the rust layer on the surface of the weathering st...
