Example Embodiment
[0043] Example 1: The preparation of the sealing agent is as follows: an emulsion is formed by dispersing calcium acetate, barium acetate, lithium silicate, ammonium acetate, titanium acetate, sodium fluorotitanate and sodium dodecylbenzene sulfonate in deionized water. The content of each component in the emulsion is calculated by weight percentage, including: 30% calcium acetate, 8% barium acetate, 5% lithium silicate, 6% ammonium acetate, 9% titanium acetate, 4% sodium fluorotitanate, 1.2% twelve Sodium alkylbenzene sulfonate, the balance is water. The sealing storage time of the above-mentioned sealing agent can reach more than one year.
[0044] Dilute the above plugging agent into a plugging liquid with a concentration of 12g / L for use; adjust the PH value of the plugging liquid to 6.0; heat the plugging liquid to 94°C; immerse the pre-treated aluminum alloy product for 15 minutes . It can make aluminum alloy products get a smooth surface, no powder frost sealing film, in...
Example Embodiment
[0045] Example 2: The composition of the above-mentioned sealing agent is calculated by weight percentage, including: 20% calcium acetate, 15% barium acetate, 8% lithium silicate, 5% ammonium acetate, 12% titanium acetate, 7% sodium fluorotitanate , 1.4% sodium dodecylbenzene sulfonate, other operations are the same as in Example 1. The sealed storage time of the above-mentioned sealing agent can be up to 2 years. In the sealing process, the concentration of the sealing material liquid is 10g / L, the PH value is 5.5; the sealing temperature is 90℃, and the sealing time is 18min, which can make the aluminum alloy product get a smooth surface and no powder frost sealing film.
Example Embodiment
[0046] Example 3: The composition of the above-mentioned sealing agent is calculated by weight percentage, including: 20% calcium acetate, 25% barium acetate, 10% lithium silicate, 8% ammonium acetate, 12% titanium acetate, 9% sodium fluorotitanate , 4% sodium dodecylbenzene sulfonate, other operations are the same as in Example 1. The sealing storage time of the above-mentioned sealing agent can reach more than one year. In the sealing process, the concentration of the sealing material liquid is 14g / L, the PH value is 6.0; the sealing temperature is 97℃, and the sealing time is 10min, which can make the aluminum alloy product obtain a smooth surface and no powder frost sealing film.
[0047] The embodiment of the present invention also provides an aluminum alloy product, and the above-mentioned aluminum alloy product is subjected to the above-mentioned sealing process with the above-mentioned sealing agent. The above-mentioned aluminum alloy products have a smooth surface, no p...
