Corrosion Test of Utensil Coating with FRP based Salt Spray Tester

Plastic has been predominantly taking active participation in the utensil industry. As they are lighter in weight and are colourful in appearance they are taking major places in the kitchen. However, many still prefer metal utensils like steel, copper or other mixed alloys. These metals may be heavy in weight but are very beneficial when it comes to longevity and health. Hence, being still in demand the manufacturers must ensure that they stay ahead of the competition by bringing high quality in their production. Fo which they need to ensure that their product stays in the market for long. That can only happen when a highly efficient coating is applied to the utensil. In this blog, we will read more about how an FRP based Salt Spray Tester can help evaluate and choose the best coating for metal utensils.

Why do metal utensils need a coating for long run performance?

Metal utensils are used for the purpose of cooking and keeping edible items, hence are never made of pure or core metal. They are always present in the form of alloys. Alloys are a mixture of one or more metals, mainly containing iron in a very smaller portion of them. These alloy products or metal utensils will of course be exposed to water that can be soft or hard, and the constituent of salt in the water can also vary from location to location. Long time exposure to the water makes the metal exposed to the oxidation process. The water molecules react with the iron molecules present in your metal utensil and can develop surface corrosion. This can further grow and destroy the product completely. Only an efficient coating or plating can act as a barrier between and protect the utensil from corrosion.

The coating layer if is of good quality can resist the corrosion building environment for long hours and protects the surface layer of utensils. But if the same layer is of bad quality material they can't resist the material surface for long hours and will invite more corrosion to develop and become the reason behind the destruction of the product. Hence, it is important to choose an ideal coating or plating that can function well and protect against or resist corrosion.

Fibre-reinforced plastic or FRP material based salt spray chamber is used for conducting artificial and accelerated corrosion testing. The chamber generates a machine-made slat fog inside where the sample is placed to test. The effect of the corrosion can be tested at the end.
