Abstract

The black corrosion inhibiting and scale retarding agent is prepared by mixing sodium humate and water soluble sulfide in certain proportion, and into the mixture, sodium methylene bis-naphthalene sulfonate, sodium salt and ash preventer. The scale retarding and water dyeing capacity of the sodium humate and water soluble sulfide are utilized. The product has high water solubility, fast diffusion, no toxicity, no smell, no toxicity, low cost and simple use, and has also effect of preventing heating pipeline from scaling.

Description

Technical field: [0001] The invention relates to a scale inhibitor for civil heating systems, specifically discloses a black corrosion and scale inhibitor, and belongs to the technical field of chemical preparations for preventing scaling in boiler pipeline systems. Background technique: [0002] At present, in the heating system, hot water is often leaked to prevent theft, resulting in loss of heat energy, and the heating efficiency of the system is not as expected. In order to prevent hot water from being stolen, dyes, diesel oil, sewage Mud and other colored or odorous substances make hot water unable to be used normally, and the embezzlement problem is solved. However, due to the corrosion and scaling of the additives on the heating system of the boiler pipeline, it seriously affects the normal and safe operation of the heating system. Invention content: [0003] The problem to be solved by the present invention is to provide a black corrosion and scale inhibitor with ...
