2. The replacement of silicone pad
The silicone pad used for a long time will make the pinholes no shrinkage, and
cause the entry of the moisture in the atmosphere, then affect the
measurement. So it should be replaced in time (see Figure 4-4).
3. The replacement of silica gel
The silica gel in the drying tube from blue to light blue, should be replaced new
silicone, do not encase silicone powder, otherwise will cause electrolytic cell
cannot exhaust, then terminate electrolysis.
4. The maintenance of electrolytic cell ground
Every 7~8 days rotate about the electrolytic cell ground, when cannot rotate
easily, should be re-coated with a thin layer of vacuum grease and reload, or
used for a long time is not easy to remove.
If the electrode cannot be removed, do not force to pull out, at this
moment the correct approach is the whole electrolytic cell all soaked in
warm water immediately for 24 to 48 hours.
5. Cleaning of the electrolytic cell
Open all the glass mouth of the electrolytic cell bottle, the electrolytic cell bottle,
drying tube, sealing plug can be cleaned with water. After washing put them in
about 80
℃
drying oven and then cooled naturally. Electrolytic electrode
cannot be washed with water; clean it with anhydrous alcohol, then use a hair
dryer to blow dry.
Cleaning should be careful not to wash the electrode line as shown in Figure
8-1.
