Silver electrode storage places: a warehouse storing silver electrode should have a dry and ventilated environment, avoid moisture; refused to water, acid, alkali and other corrosive liquids in the presence of highly volatile substances, but not with these substances coexist in the same warehouse. Electrodes should be placed on wooden pallets, it can not be placed directly on the floor or against the wall. II. Be careful when handling the access and do not break the rod packing, especially in the packaging "shrink film." Open silver electrode packaging should soon be fully utilized (requires a week or less), once the wire is directly exposed to the air, it will greatly shorten the time-rust (especially in the wet, there are environmental corrosion medium). Three. According to the principle of "first in first out" the release rod, minimizing inventory time. Press rod categories, specifications classified storage, to prevent misuse
