Abstract

The invention discloses a boiler descaling agent and a preparation process thereof. The boiler descaling agent is prepared from, by weight, 30-40 parts of organic acid, 15-20 parts of ethanol, 5-10 parts of an organic solvent, 8-12 parts of 8-hydroxyquinoline, 2-6 parts of a corrosion inhibitor and 12-40 parts of deionized water. The preparation process comprises the steps that S1, 8-hydroxyquinoline is dissolved in an ethanol solution to obtain the ethanol solution of 8-hydroxyquinoline; S2, the organic acid, the organic solvent, the deionized water and the ethanol solution of 8-hydroxyquinoline are mixed, the corrosion inhibitor is added, and then a finished product solution is obtained; S3, the finished product solution is bottled and packaged to obtain the boiler descaling agent. The boiler descaling agent is high in descaling speed, good in descaling effect, convenient to use, wide in application range and capable of effectively removing scale, oil dirt and rust scale, protecting equipment after descaling and prolonging the service life of the equipment, the preparation process is simple, raw materials are easy to obtain, and cost is low.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a boiler descaling agent and a preparation process thereof. Background technique [0002] The boiler will inevitably produce scale after long-term use, and the formation of these scales will seriously affect the heat transfer of the boiler and reduce the working efficiency of the boiler. Scale is divided into hard scale and soft scale according to the cause and form of formation. The main components of hard scale are carbonates, sulfates, silicates and phosphates, etc.; the main components of soft scale are iron scale, copper scale, etc. [0003] The existing descaling methods mainly include magnetization descaling, electrostatic descaling, frequency conversion resonance descaling, acoustic descaling and chemical descaling. The equipment required for the first four descaling methods is expensive and difficult to implement, which increases the cost of use. Therefore,...
