Four, process description
When using this product and water according to the (volume C can use, ratio) water dilution for working fluid, stir heating to phosphating time minutes. The new match work fluid to pass try phosphating qualified rear can batch production.
1. Test: take work fluid ml of triangle flask, and distilled water ml, dropdrops of methyl orange indicator, with 0.1 N sodium hydroxide standard solution titration to orange as an end, at this time ?the consumed N sodium hydroxide ml number by for Fa; And then drop four drops phenolphthalein indicator, continue to use N sodium hydroxide standard solution titration to appear red as an end, at this time the consumed N sodium hydroxide total ml number byAdjustment: when the Fa additional sodium carbonate, every? fill water; When the Fa ?When Ta litres of working fluid with grams of sodium carbonate, Fa reduce 1 point.
4. Note added groove in the moisture volatilize, Regular cleaning groove bottom sediment.
