Antiseptic antibiotic oil paint additive

Abstract

The invention discloses an anti-corrosion and anti-bacterial paint additive, which is mainly used for anti-corrosion in certain metal parts requiring anti-corrosion treatment in sewer facilities of apartments, river banks, mines, municipal engineering, etc., or in anoxic acidic environments. It is mainly composed of zeolite powder, nickel metal powder and tungsten metal powder. The present invention does not affect the normal use of some particularly important metal parts in sewer facilities or anoxic and acidic environments, and can conveniently protect some particularly important metal parts in sewer facilities or anoxic and acidic environments under current conditions. Reduce construction cost. By coating paints containing this additive, the normal service life of some particularly important metal parts in sewer facilities or anaerobic acidic environments can be extended and maintenance costs can be reduced.

Description

technical field

[0001] The invention is an anti-corrosion and anti-bacterial paint additive, especially an anti-corrosion and anti-bacterial paint additive mainly used in sewer facilities such as apartments, river banks, mines, municipal engineering, etc., or some metal parts that need anti-corrosion treatment in anoxic acidic environment . Background technique

[0002] The corrosion of metal parts in sewers or other anoxic acidic environments is often caused by the action of chemicals and microorganisms in water. The mechanism and chemical reaction are as follows:

[0003] (1) In sewer or anoxic acidic environment, sulfate in sewage is reduced to hydrogen sulfide by anaerobic sulfate-reducing bacteria.

[0004] SO 4 2- +2C+2H 2 O=H 2 S+2HCO - 3

[0005] (2) Hydrogen sulfide diffuses into the gas phase and dissolves in the condensation water of metal parts, and then oxidizes it into sulfuric acid by aerobic sulfur-oxidizing bacteria.
