Technical features

FIPROPLUS 935 is a neutralizing product to be used after acid treatment and has a significant antioxidant action in the passivation phase. The use of this formulation is recommended for closing cycles of phosphating, acid pickling or degreasing of particularly delicate ferrous material. It is also indicated and recommended as an antioxidant additive in hydro-pneumatic test baths, an excellent passivating agent for iron and cast iron products.

Applicazione
Concentrazione

Bath preparation

The product is diluted in water (preferably demineralized) to the most suitable concentration required for its use.

Passivating neutralizer 10-60 g / lt
Antioxidant for hydraulic tests 3-10 g / lt
Antioxidant for final washing 5-15 g / lt
Passivations for interoperational storage 30-50 g / l

Control of bathing

The bath control is performed by chemical titration according to the following method:

Using a calibrated pipette, exactly 10 ml of bath are taken, diluted with 20-30 ml of demineralized water and added to 4-5 drops of green indicator solution of bromcresol. The liquid, which will take on a blue color, will be titrated with a 0.1 N hydrochloric acid solution until it changes from blue to yellow.

The n ° of ml of Acid used for the color change will correspond to the score of the bath whose concentration can be traced by consulting the following:


CONCENTRATION [g/l]             POINT [ml hydrocloric acid 0.1 N]


                  5                                                         2,9

                 10                                                        5,7

                 20                                                      11,4

                 30                                                      17,1

                 40                                                     22,8

                 50                                                     28,5

Alimentation

For each missing point and for every 1000 liters of bath, add 1.8 kg of product.

Stoccaggio

Store the product away from direct sunlight and heat sources. The product cannot stand freezing: store at temperatures above 5° C.
