Configuration method (calculated by 1 ton)

1. Add water to the 1/2 volume of the tank in the phosphating tank.

2. Add 50kg of ZQ-601 phosphating concentrate directly to the phosphating bath.

3, make up the remaining amount of water to the working level, while stirring the tank liquid.

4, then add 0.6KG neutralizer, stirring uniform bath; Usage: First add 0.6KG neutralizer to 5KG of water, and then slowly poured into the bath.

5, add 8KG accelerator, stir evenly to use;

6, confirm the free acidity and total acidity in the specified range.

Testing method

1, Determination of total acidity (titration).

10ml pipetting solution to be measured with 10ml phosphating working solution in a 250ml Erlenmeyer flask, add 50ml of distilled water, add 2-3 drops of phenolphthalein indicator, using 0.1N standard sodium hydroxide solution titration to red end, the consumption The milliliter of 0.1N sodium hydroxide solution used is the point of total acidity, ie, 1 ml is the "1" point.

2, the determination of free acid:

Pipette 10ml of the phosphating solution to be measured in a 250ml Erlenmeyer flask with a 10ml pipette, add 50ml of distilled water, add 1-2 drops of bromophenolphthalein blue indicator, and titrate with a 0.1N standard sodium hydroxide solution to make the solution blue end. The number of milliliters of 0.1N standard sodium hydroxide solution consumed is the number of free acidity points, ie 1 ml is the "1" point.

3, accelerator concentration:

Take appropriate phosphating working solution into the fermentation tube, then add sulfamic acid 2-5 grams, and after vibrating up and down, the scale shows the amount of gas production readings (number of ticks) points of the accelerator concentration, 1 scale is " 1 point, its concentration is 2-5 points.

In the phosphating process, it is necessary to make up for each shift or daily before the start of work in accordance with the amount of work to be performed, so that the indication of the replenishment liquid and promoter is controlled within the range of the process, and the service life of the phosphating solution is prolonged.

Adjustments and Additions (calculated by 1 ton)

When the processing capacity of the phosphating bath is reduced, it can be added in proportion to restore the technical indicators and achieve the ideal phosphating effect. The supplement should be based on the principle of “difficult to increase, increase less”. When there is more sediment, it is required. Clean slag in time, add phosphating concentrate to phosphating working liquid surface by 5%, add water to the required working liquid level, and then detect and adjust according to the preparation method until it can reach the working index. .

The end of the solution is blue, and the number of milliliters of 0.1N standard sodium hydroxide solution consumed is the number of free acidity points (normally undetectable).

Adjustments and Additions (calculated by 1 ton)

When the processing capacity of the phosphating bath is reduced, the ratio can be added in proportion to restore the technical indicators, to achieve the desired phosphating effect. The supplement should be based on the principle of “difficult to increase, less increase,” when there is more sediment, then The slag must be removed in time, and the phosphating solution must be added to the phosphating solution at 5% in accordance with 5% of the phosphating solution. The water should be added to the required working fluid level, and then tested and adjusted according to the preparation method until it reaches the working index. use.

Precautions

1. Before the ZQ-603C phosphating treatment, the oil, rust, and phosphatized skin on the metal surface must be completely removed. After sufficient washing, the phosphating process can be performed and the acid, alkali, dirt, impurities, etc. can be prevented. Brought into the phosphating bath, affect the use of phosphating solution and life.

2. When the phosphating effect is not satisfactory, the total acidity is detected and the phosphating solution is added.

3, after phosphating can be washed, or not washed, naturally air-dried or baked dry, best baked.
