    Agricultural Equipment

    Securing long-term function is a key role for the fasteners and construction elements in agricultural machinery and equipment. In addition, retaining the optical appearance of the expensive capital goods is also important. The components need to be protected in particular from the constant assault of fertilizer granulate, pesticides and liquid fertilizer (AHL).

    Fastening ElementsSprings

    Fastening elements are used in various sizes and geometries in agricultural machinery and equipment. Not only do they have to be protected against corrosion and chemicals, functional characteristics such as good threadability also need to be retained.

    The coatings of springs used in agricultural machinery and equipment need to satisfy high corrosion protection requirements. At the same time, sudden failures due to hydrogen-induced stress corrosion cracking need to be avoided.

     

    Requirements

    • Corrosion protection (720 h as per DIN EN ISO 9227)
    • Coloring (silver or black)
    • Sliding properties
    • Abrasion resistance
    • Coefficients of friction
    • Chemical and fertilizer resistance
    • Stone impact resistance

    Solutions

    Thanks to its excellent cathodic corrosion protection, the zinc flake technology from DÖRKEN helps prevent the premature failure of components, extend the lifetime of machinery and retain value. At the same time, the zinc flake coating has a very high level of chemical resistance and can therefore be used to coat components. A further advantage: no hydrogen is generated in the coating process, with the result that no application-related, hydrogen-induced stress corrosion cracking occurs.

    Livestock Buildings

    Livestock buildings are exposed to high weather stress, such as wind and rain. To secure the functionality and appearance and achieve as long a lifetime as possible, the components utilized require long-term protection against these effects. At the same time, the parts and components used in the livestock buildings are subject to a range of chemical influences - for example from the recurring cleaning cycles, or ammonia. In livestock rearing in particular, maintaining a food-safe surface is also important.
