collector resistance
1.This is portable pump with strong suction and medium head doss,equiped with extraordinary hair collector;the body is made of themal plastic of strength ening fiberglass with good corrosive and impact resistance;and with the advan tages of high flow ,quiet.
2.Three types of chemical polishing processes for the current collector of alkaline Zn/MnO2 battery were racommened including the H2SO4 - NaNO3 - HCI solution, the H2O2 - HNO3 solution and two - step polishing with bright carbon black. The performance of current collector polished was investigated by means of many methods, such as the volume of evolved hydrogen, contact resistance, EDX, the short circuit current, the capacity of the corresponding batteries and the compatibility with the environment.
