Ductile iron pipes -
Electrochemical protection potential of iron is 0.
440 mv, and potential of zinc is 0.
The low voltage of 763 mv, than iron, oxygen potential to 1.
The zinc oxide the potential difference between the larger, more likely to form a galvanic cell, which will cast
iron pipe wall are protected.
Form a stable layer of protection in the process of contact with the soil environment, materials such as metal zinc carbonate in soil combined into insoluble zinc carbonate, this layer of protective film tightly bonding on the wall, form a layer of dense continuous, insoluble and leakage of the coating.
Coating on the zinc layer asphalt sealing pore also has an important role, can promote the dissolution of zinc layer into a stable and zinc salts.
Damage of self healing in pipeline transportation and installation process, the local damage may occur.
Under the action of zinc in the galvanic cell quickly into zinc ions.
Zinc ions migration of the role of sealing the pores through the asphalt layer and cover damage, forming stable and insoluble zinc layer protection.
One increasingly popular managerial tactic to improve problem-solving performance of cast iron suppliers
is to increase the connectedness, or what academics call clustering, of the organization
Guangzhou Xinerxun Metal Trading Co., Ltd. endeavors to be valued as an industry leader in client satisfaction, sales growth, product performance, financial strength and profitability.
