Strong suppression of gray Degreaser

Features Acid Degreaser is a colorless liquid, the degreasing agents, strong oxidizing agents, corrosion inhibitors, brighteners, suppression of gray agents, surface active agent compound made as smooth front profile or powder processing aluminum degreasing. Decontamination capability, post-processing profile surface bright and clean. Moderate foam, easy to clean. Too easy to produce corrosion, aluminum consumption is small. Bath process parameters width, easy to control, no etching sand surface, such as bath pollution. Second, with bath method and process parameters: 2.1 with bath method: add 先向 tank under running water to the required level line about 500-1000mm, the state added under stirring an acidic degreaser. Amount is calculated as follows. Finally water to the required level. Stir Acidic Degreaser: 30 ~ 50g / l (oxidation 30g / l, spray 50g g / l) 2.2 Process parameters: free acid: 5.0 to 10.0 operating point of aluminum ions: ≤30g / L Temperature: room temperature Time: 2 ~ 8min (depending on the thickness of the reservoir be extended or shortened) Third, add and process management 1. According to the production of the production process additional acidic degreasing agent, generally deal with spray paint consumption 3-5KG / ton; oxide material consumption 1.5-2.5KG / ton. 2. During the operation to avoid the debris into too dirty, contaminated bath, advisable once a month to clean the bottom. Fourth, bath detection method pipette imbibe 10mL bath in 250mL Erlenmeyer flask, add 50mL distilled water, plus 2 to 3 drops of 1% phenolphthalein indicator, titrated with 1N NaOH to the solution from colorless to Pink is the end, not a note within 30S fade V1, pipette imbibe 10mL bath in 250mL conical flask, add 50mL distilled water, 5g of potassium fluoride, dissolved shake, plus 2 to 3 drops 1% phenolphthalein instructed agents titrated with 1N NaOH to the solution from colorless to pink is the end, do not fade in the 30S note of V2. Total acid (work points) = V1 * N free acid (work points) = V2 * N aluminum ion (g / l) = 1.8 * N * (V1-V2)
