Definitions
- the present invention relates to the use of zinc alloys as construction zinc for strips and sheets.
- strips and sheets made of alloyed zinc for construction purposes contain, apart from zinc, a content of 99.99% 0.005 to 0.05% by weight aluminum and additions of 0.05 to 0.2% by weight titanium and copper.
- This alloy is described, for example, in DE 17 58 498 and corresponds to DIN 17 770, part 1.
- This material is generally produced using the casting-rolling process, in which strips are produced in predetermined thicknesses in an uninterrupted ner-process step (melting - casting - rolling - winding), which are then cut into narrow strips or sheets on scissor lines.
- This material is very stable in the atmosphere.
- the surface initially reacts with the oxygen in the air to form zinc oxide.
- the action of water then forms zinc hydroxide, which is converted into a dense, firmly adhering and water-insoluble cover layer of basic zinc carbonate by reaction with the carbon dioxide in the air.
- This protective layer is also responsible for the high corrosion resistance of such strips and sheets.
- the underside of the zinc strips and tablets In contrast to the behavior of the surface of the zinc facing the free atmosphere, the following applies to the underside of the zinc strips and tablets, ie to that of the Weather-facing side, other criteria. If, in addition, the underside of the zinc strips and sheets is exposed to moisture or condensed water for a long period due to inadequate ventilation, increased corrosion due to these structural and installation errors must be expected. Such water inclusions, water ingress and condensation eventually lead to point-by-point deep corrosion (pitting), which can spread out in areas.
- DD-4822 discloses the use of zinc aluminum alloys which contain 1 to 63% aluminum and 99 to 37% zinc, which are made suitable by a special heat treatment for objects with high resilience, ie the so-called superplastic behavior. This is important for the drawing of wires as well as rolling, extrusion, forging, deep drawing of metal sheets and when bending. There are none Indications of the corrosion behavior of these alloys and thus their usability as construction zinc for strips and sheets.
- DE-30 07 850 C describes the use of a zinc alloy as a powder for mechanical plating. In addition to improved corrosion resistance, above all a perfect adhesion of the coating to the base should be achieved. It is therefore another use than that of these alloys as construction zinc for beams and sheets.
- the task of providing strips and sheets of alloyed zinc as building zinc that meet even higher requirements is now achieved by adjusting the aluminum content in particular to 5 to 35% by weight, preferably 5 to 20% by weight. , in particular 8 to 15% by weight. Further improvements are achieved by alloying 0.002 to 0.04% by weight indium and / or 0.002 to 0.04% by weight calcium and / or 0.002 to 0.4% by weight titanium and / or 0.05 to 0.8% by weight of manganese. Copper, iron and lead should only be included in the amounts that are inevitable as contamination of the zinc and aluminum. Further improvements in the properties are possible with 3 to 100 ppm boron, 3 to 100 ppm carbon, 3 to 50 ppm magnesium, 2 to 500 ppm vanadium, 2 to 500 ppm silicon and / or 2 to 500 ppm nickel.
- the improved properties of the alloys used according to the invention result from comparative corrosion tests with the salt spray test according to DIN 500 21-ss (aging 7 and 14 days) and the denswasser / S0 2 test according to DIN 50 018 KFW 0.2s (aging 22 cycles). After aging, the changes in mass and the visual appearance of the corrosion of the sheets are determined.
- the preferably alloyed elements indium, calcium, titanium and manganese mainly affect the mechanical properties, but also improve the corrosion behavior. Particularly good results are achieved with alloys with an aluminum content of 5 to 20% by weight aluminum, the range from 8 to 15% by weight aluminum being particularly preferred.
- Impurities of more than 0.1% by weight of copper and more than 0.1% by weight of iron lead to deteriorated mechanical properties and, in particular, increase intergranular corrosion. These metals and other impurities should therefore only be present in the usual unavoidable amounts.
- indium, calcium, titanium and manganese can be increased in principle, but this only leads to an unnecessary increase in the cost of the material without significantly improving the properties.
- the strips and sheets that can be used as construction zinc can be produced by the usual casting-rolling process.
- all zinc qualities according to EN 1179 can be used as zinc qualities, with the zinc grade ZI being preferred because it contains relatively little lead, iron and copper.
- Aluminum as an alloy component is preferably used in the qualities according to EN 576.
