| T-72 | 0.0278 | 0.0499 | 0.0768 | 0.0885 | 0.1089 |
It can be seen from table 5, copper covered steel nickel plating is tin plating in 5 kinds of electrodes wraps up in carbon nanotube electrode, even if long-term use, its for
The adsorption effect of protein and the cleaning performance of contact lenses, remain in that higher level, and are left 4 kinds of electrode useful life longevities
There is different degrees of reduction, reason includes following several：1) verdigris is generated after copper long-term use so that electrode conductivuty is deteriorated；
Although 2) silver-colored electric conductivity highest, is oxidized easily as anode, using effect is influenceed；3) metal electrode after nickel plating is resistance to
Corrosion has obtained very big lifting, but corrosion resistance is not high under nickel coating electrode has acid solution；4) it is tin plating after nickel plating
Electrode, further protects nickel dam, improves the corrosion resistance of metal electrode, while tin layers surface flatness is less than nickel dam, can be with
Improve the adsorption effect of protein.
The above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, on the premise of the technology of the present invention principle is not departed from, can also make it is some improvement and
Modification, these are improved and modification also should be regarded as protection scope of the present invention.
