Definitions

the invention relates to a method for producing Protective layers of uniform color tint on rolled Flat products made of titanium zinc in the form of strips, sheets and strips for use in construction.
titanium zinc initially reacts in the atmosphere with the formation of zinc oxide with the oxygen in the Air. It is formed by the action of rain and moisture then zinc hydroxide, which is caused by the reaction with the carbon dioxide the air into a dense, adherent and water-insoluble Protective layer for basic zinc carbonate, the so-called Patina, is transformed. This protective layer is in generally responsible for the high corrosion resistance of the titanium zinc.
DIN EN 988 titanium zinc consists of 0.06 up to 0.2% by weight titanium, max. 0.015% by weight aluminum, 0.08 to 1.0 % Copper, balance zinc 99.995% by weight.
Sulfur dioxide affects at a relative humidity of over 70% the formation of the protective layer of the Titanium zinc.
the protective layer complements the removal or Damage due to consumption corresponding to this removal of zinc.
the aggressiveness of the local atmosphere is different and thus the intensity of the atmospheric Corrosion.
the formation of the protective layer from basic zinc carbonate needs one depending on the season, climate and environmental conditions more or less long period, the training of Zinc carbonate layer is not done regularly and thereby optically negative impression arises.
Claims 2 to 8 preferably contain and / or others Design options of the method according to claim 1.
the speed of the pickling reaction is essentially dependent on the free acid content.
the reduction of nitric acid is the dominant reaction and prevents one Hydrogen evolution.
Another influence on the pickling result exerts the ratio of acidity.
a tape made of titanium zinc 0.8 mm thick and 600 mm Width is achieved by rinsing with an alkaline degreasing solution at a temperature of approx. 60 ° C and a pressure of degreased approx. 2.5 bar and then in a sink with water with a temperature of 65 ° C and a pressure of 2.5 bar hosed.
the belt is brushed in the last rinse stage.
the belt is then used in a pickling line a pickling bath temperature of approx. 50 ° C, containing a mixed acid from approx. 30 to 60 g / l sulfuric acid and approx.
the Belt emerging from the pickling line is described as above rinsed with water. After removal of the residual water is on the tape by rolling a mixture of 95% polymers and 5% Chromate solution applied and this application at approx. 80 ° C dried.
the layer thickness of the film produced is dry condition 1.5 ⁇ m. That is under the light microscope Layer not recognizable.
a condensation test was carried out with two belt sections DIN 50017 (8 hours including warming up at 40 ° C and 100% humidity, then 16 hours cooling with the chamber open) carried out. After repeating this test 10 times no formation of zinc hydroxide was found. A At the same time, the test was carried out on titanium zinc sheet, which was pickled by the process according to DE-C-2 757 592, showed extensive formation of zinc hydroxide.
the deep-drawing behavior of the strip sections treated according to the invention was tested by pulling out the two band sections Blanks were cut using a press Elbow half-shells were deep drawn. There were both deep-drawn and non-oiled boards deep-drawn; Flaking the passivation layer was not visible anywhere.
