Low Foam Metal Pretreatment Chemicals Powder With Strong Permeability
Metal Pretreatment Chemicals Powder introduction
Metal Pretreatment Chemicals Powder Is a compound of surfactant with super penetration and emulsification, complexing agent, help lotion, has strong permeability, wettability, emulsification, natural biodegradable, in line with general international environmental protection standard. Commonly used as oil removal chemical in automobile, motorcycle, bicycle, household appliances, lighting, daily hardware and sanitary ware, such as all kinds of steel pieces before electroplating.
Metal Pretreatment Chemicals Powder Application
Be suitable in dipping and degreasing for steel/stainless steal/aluminum/aluminum alloy and zinc alloy work pieces.

Aluminium Ion Content:
Metal Pretreatment Chemicals 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 JH1102 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.
