Mode of action
For systems that are closed to the atmosphere, offering themselves to the oxygen-free driving. Because the dose of oxygen scavengers is this the corrosion completely excluded.
For systems that are open to the atmosphere, the passivation of the system parts made by appropriate inhibitors.
The GEWA - corrosion inhibitors are known Absorbtionsinhibitoren. The effect of these protective substances is based essentially on the fact that - is formed in equilibrium with the aqueous phase - a Absorbtionsschicht on the material surface. The protective layers are formed by X-ray detectable. The resulting reduction in heat transfer is practically not measurable, that is not relevant. The stability of this inhibitor layer is dependent on the concentration in the aqueous phase. Therefore, the continued adherence to an effective product concentration for the protection of plant parts is essential. An automatic dosing system ensures maximum security.
With the use of corrosion inhibitors GEWAT it is important not only to a virtual standstill of the corrosion processes, but in technical systems greatly disturbing and undesirable material transport, eg of corrosion products, can - if necessary blocked - in conjunction with cleaning and filtration measures.
It should be noted that the corrosion inhibitors include dispersants, so that it can come on the one hand, in existing plants without first cleaning the transport of corrosion products in the systems.
On the other hand, the dispersive properties of these products can be used if necessary in combination with filtration steps for easy and safe cleaning of the systems
