Embodiment 1
[0014] Step 1: Put 350 conductive rods into the bucket of the light rod machine, first add 1kg of 10% dilute sulfuric acid and mix the conductive rods. Then add 7kg of fresh rice husks, and turn the light rod machine to scrub the conductive rods and rice husks;
[0015] Step 2: After rotating for 15 minutes, sieve the chaff. Then add 1kg of 10% dilute sulfuric acid for the second pickling, and finally wash it with water, and quickly wipe it dry. The bend should be straightened or replaced;
[0016] Step 3: When casting the anode sheet, apply a uniform and thin anti-oxidation protective film on the surface of the conductive rod.
[0017] After observing an electrolysis cycle, the measurement results of the voltage drop at the contact points of the normal production cell and the antioxidant-coated electrolytic cell are compared as follows:
[0018] Comparison of measurement results of contact voltage drop mV
[0019] Power-on time / h
Embodiment 2
[0021] Step 1: Put 350 conductive rods into the bucket of the light rod machine, first add 1kg of 15% dilute sulfuric acid and mix with the conductive rods. Then add 8kg / time of fresh rice husks, and turn the light rod machine to scrub the conductive rods and rice husks;
[0022] Step 2: After rotating for 15 minutes, sieve the chaff. Then add 1kg of 15% dilute sulfuric acid for the second pickling, and finally wash it with water, and quickly wipe it dry. The bend should be straightened or replaced;
[0023] Step 3: When casting the anode sheet, apply a uniform and thin anti-oxidation protective film on the surface of the conductive rod.
[0024] After observing an electrolysis cycle, the measurement results of the voltage drop at the contact points of the normal production cell and the antioxidant-coated electrolytic cell are compared as follows:
[0025] Comparison of measurement results of contact voltage drop mV
[0026] Power-on time / h
Embodiment 3
[0028] Step 1: Put 350 conductive rods into the bucket of the light rod machine, first add 1.5kg / time of 20% dilute sulfuric acid and mix with the conductive rods. Then add 10kg of fresh rice husks, turn the light rod machine, so that the conductive rod and rice husk scrub each other;
[0029] Step 2: After rotating for 20 minutes, sieve the chaff. Then add 1.5kg of 20% dilute sulfuric acid for the second pickling, and finally wash it with water and dry it quickly. The bend should be straightened or replaced;
[0030] Step 3: When casting the anode sheet, apply a uniform and thin anti-oxidation protective film on the surface of the conductive rod.
[0031] After observing an electrolysis cycle, the measurement results of the voltage drop at the contact points of the normal production cell and the antioxidant-coated electrolytic cell are compared as follows:
[0032] Comparison of measurement results of contact voltage drop mV
[0033] Power-on time / h
