Zinc anode

The self-erosion rate of zinc anode is relatively low, which is about 0.02g.m-2.h-1 in cold fresh water, corresponding to the erosion rate of 25 ohms. A-1.

Zinc anodes are characterized by low surface polarization, high current efficiency, wide material sources and low price.

Zinc is suitable for seawater, steel pile wharf and ship hull using zinc anode.

Executive standard:

GB/T4950-2009 ASTM-B-418-73

Marine zinc anodes are divided into single foot, double foot welded, and bolted joint type.

The disadvantage of zinc anode is that its protective potential (-0.85V) excitation voltage is

small compared with iron, only 0.25V, which is commensurate with 1/3 of magnesium anode.

Therefore, its application scope is relatively narrow.In cold water, the rate of self-erosion was

approximately 50% higher {10}.Auxiliary products include: reference electrode,

aluminothermic welding die, insulated joint, insulated bracket, point gun, explosion-proof

junction box and other cathodic protection products.These figures were measured in inactive

water.

RCEP is the abbreviation of English RegionalCom - prehensiveEconomicPartnership.It is the first regional economic integration cooperation proposed by ASEAN countries in recent years and led by ASEAN. It is a form of organization in which member countries open their markets to each other and implement regional economic integration.The RCEP's main members plan to include countries that have signed free trade agreements with ASEAN, namely China, Japan, South Korea, Australia, New Zealand and India.The 10 ASEAN countries have signed five free trade agreements with each of the six, including a free trade agreement with Australia and New Zealand.These 16 countries are currently planned to form the RCEP. The other two EAS members (the US and Russia) do not have free trade relations with ASEAN, so they are not included in the RCEP member countries' plan.Asean plans to negotiate the accession of the United States and Russia after the 16 countries have built the RCEP to a certain extent.
