Abstract

The invention discloses a scale removal and prevention agent for a boiler and a preparation method of the scale removal and prevention agent. The scale removal and prevention agent is prepared from the following raw materials in parts by weight: 25-60 parts of citric acid, 15-35 parts of hydrochloric acid, 12-40 parts of sodium chloride, 12-35 parts of sodium hexametaphosphate, 8-25 parts of sodium pyrophosphate, 13-25 parts of acrylic acid, 8-22 parts of ammonium nitrate, 8-19 parts of sulfamic acid and 35-60 parts of de-ionized water. The scale removal and prevention agent can be used for different boilers, the scale prevention rate reaches more than 95%, and the energy consumption of the boiler is remarkably reduced.

Description

technical field [0001] The invention relates to the field of descaling agents, in particular to a boiler descaling and antiscaling agent and a preparation method thereof. Background technique [0002] In the process of industrial production, boilers often generate scale, which will increase energy consumption and increase production costs. The antiscaling agent in the prior art has the following disadvantages: firstly, it is used in a large amount; secondly, the antiscaling effect is low; and furthermore, it has a corrosive effect on the boiler itself. Therefore, it is very important to develop an anti-scaling agent with good anti-scaling effect, non-toxic, non-corrosive, safe and reliable, and easy to operate. Contents of the invention [0003] Technical issues solved: [0004] In order to provide an anti-scaling agent with long drug effect release period, good anti-scaling effect, non-toxic, non-corrosive, safe and reliable, and easy to operate, the invention provides ...
