Suggestion on Prolonging the Service Life of the Electric Heating Wire in washing machine element


1.when making a choice of selecting what kind of heating wire, it is important to have a clear mind. The heating wire selection can directly determine the heating wire application life, often there are many customers come to us to consult which kind of wire is good and with long service life. We generally suggest them to give us parameters of the heating wire. 

2. choosing the thickness of the heating element material with thick or thick wire diameter has a direct impact on the life of the element, the diameter of the wire is added, the appearance of each unit has more alloy composition can constitute a new corrosion. Therefore, at a given temperature, the life of the thicker linear element is longer than that of the young, and likewise, the life of the thicker strip element is longer than that of the thin strip element. Generally at the highest application temperature of the components of the task its alloy diameter should not be less than 3.0 mm, flat belt thickness should not be preferred and 2.0 mm.

3. the development of pre-oxidation treatment if the element can be pre-oxidation treatment before using heating wire, so that the surface of the element to produce a relatively pure corrosion film, can prolong the service life of the element. Theory has proved that in order to lose the overall long service life, can also follow the application situation, reoxidation once every once in a while.
