Abstract

The invention discloses a corrosion prevention inhibitor for white copper B30, belonging to the technical field of corrosion and protection of metal materials. The solute of the inhibitor is prepared by combining polyepoxy succinic acid (PESA), Na2SiO3 and ZnSO4 based on the mass ratio of 0-10 to 0-20 to 0-20; the solvent is deionized water; the final inhibitor concentration is 10-50mg / L. When the concentration of the inhibitor prepared by combination is 2mg / L PESA+10mg / L Na2SiO3+20mg / L ZnSO4, the corrosion current density is the lowest, namely 0.3042mu A / cm2, and the corresponding inhibition efficiency is the highest, namely 93.05%. The corrosion prevention inhibitor for white copper B30 of the invention does no harm to the environment and has good inhibition effect on corrosion prevention of the white copper B30 in the system after being used by combination.

Description

technical field

[0001] The invention relates to a cupronickel B30 anti-corrosion and corrosion inhibitor, which belongs to the technical field of metal material corrosion and protection. Background technique

[0002] At present, due to the intensification of metal corrosion, more and more corrosion inhibitors are used. Especially for the research on the corrosion inhibition of cupronickel B30, some corrosion inhibitors currently used will more or less cause harm to the environment, which is not conducive to sustainable development. With the development of the national economy and society, water treatment technology for the purpose of resource conservation and environmental protection has developed rapidly, and the application of corrosion inhibitors is very common. The corrosion inhibitors currently studied are mainly organic substances containing N, S, O or other functional groups, such as BTA, which has been used in industry for several years. However, a serious disadvan...
