The protection of heat pipe has been commonly used, and almost all of water heater is mounted with magnesium bar.
But an extension of the magnesium bar as sacrificial anode, it is the service life for possessing oneself certainly.Normal product has
A specified service life, magnesium bar is same, and generally 2 years, this service life was not measured with the volume size of magnesium bar.Magnesium bar is made
For a corrosion substitute, its service life is decided by that the corrosivity of corrosive medium is strong and weak.Half can only be used in the place of water quality inferiority
Year in addition it is 2~3 months shorter.Magnesium bar is as the deep component ensconced in liner, and what time it runs out of at present, be it is unclear,
It can not often open and look at magnesium bar Expenditure Levels.But if being regularly replaced according to the ideal service life of magnesium bar, just certainly
It can not accomplish timely and effective.Because the water quality in each place is different, the frequency of use of water heater is different, and when more magnesium bar
Change is that just benefit is also difficult to hold really.If replacement results in wasting in advance, but delay, it will liner for some time
