Heavy Duty Metal Pretreatment Chemicals Degreasing Powder For Stainless Steel

Heavy Duty Metal Pretreatment Chemicals Degreasing Powder For Stainless Steel

Metal Pretreatment Chemicals Degreasing Powder Purpose and Characteristic:

1. Applied to degrease the zinc alloy and the copper before plating and phosphating and spraying.
2. Very small alkali, not damage the zinc alloy, restores original color after cleaning.
3. The zinc alloy won’t change the color after soaking a long time.

Metal Pretreatment Chemicals Degreasing Powder features

1) efficient to move collars ,cuffs and socks stains

2) water saving ,time save

3) washing: in cool, normal ,warm temperature are effective

4) good package design can save containers space

5) specifications extend from 15g to 550Kg by bags or cartons. Or as customer requirement.

Metal Pretreatment Chemicals Degreasing Powder Detecting method:

Free alkalinity: pipet 10ml sample into 250ml conical beaker, add 2-3 dripping phenolphthalein indicator, after drop 0.1N hydrochloric acid till pink disappear. The consumption of the hydrochloric acid is same as free alkalinity.

Tatol alkali: pipet 10ml sample into 250ml conical beaker, add 2-3 dripping Bromine phenol indicator, after drop 0.1N sulphuric acid till green disappear. The total consumption of the sulphuric acid is same as total alkali.

We could calculate the ratio between total alkali and free alkalinity(TFR).

We could add 2kg JH1104 per 1000L BATH SOLUTION when free alkalinity increase 1point. The TFR will increase together with the Total alkali, and we could detect the pollution according to TFR.

Bath solution control: Max TFR will be different according to the different workpiecessolid impurity and temperature. We could drain the bath solution regularly in continuous flow or automatic flow to maintain the TFR lower than MAX TFR.
