titleOfInvention | Activation technology for aluminum alloy electroplating pretreatment |
abstract | The invention discloses an activation technology for aluminum alloy electroplating pretreatment. An activation liquid used by the technology comprises 45-55g/L of phosphoric acid, 23-27g/L of potassium pyrophosphate, 12-14g/L of potassium tetraborate, 34-38g/L parts of acetic acid, 13-15g/L of potassium fluoride, 6-8g/L of potassium carbonate, 7-9g/L of ammonium sulfate, 32-36g/L of sodium phosphate, 6-8g/L of ammonium hydrogen fluoride, 0.5-1.5g/L of thiourea, and the balance of water. The activation technology comprises the following steps: preparing the activation liquid, adding the activation liquid into an activation tank, diluting in accordance with a ratio of 1:2-4, heating to 60-70DEG C, putting oil and dirt removed aluminum alloy in the activation tank, and activating for 6-10min. |
