Abstract

The invention discloses a neutral environment-friendly cleaning agent as well as a preparation method and application thereof. The cleaning agent comprises the following components in percentage by mass: 10-30% of a descaling agent, 0.5-3% of a penetrant, 5-10% of a cosolvent, 0.5-5% of a stripping agent and 1-5% of a pH regulator, with the balance being demineralized water. According to the neutral environment-friendly cleaning agent provided by the invention, calcium sulfate and composite scales thereof can completely react at one time in a short time at normal temperature, a removal rate is 98% or above, and time and labor are saved; the pH value is neutral, so metal equipment is not corroded, and the phenomenon of hydrogen embrittlement is avoided; the agent is free of toxicity and harm to human bodies; the agent does not contain phosphorus, can be completely biodegraded, and does not influence the environment when being directly discharged; and parking or non-stopping cleaning can be carried out according to actual requirements.

Description

technical field [0001] The invention relates to the technical field of industrial cleaning, and discloses a preparation method of a neutral environment-friendly cleaning agent, the neutral environment-friendly cleaning agent prepared by the preparation method and its application to industrial calcium sulfate complex scales. Background technique [0002] Calcium sulfate and its composite scale produced in industrial systems and pipelines are hard and dense, and difficult to remove. When the concentration of hydrochloric acid is 2mol / L, the dissolution rate of calcium sulfate is 14%, but it is more corrosive to metal equipment. [0003] At present, the industry mainly adopts the method of phase transformation or organic complexation to deal with calcium sulfate scale. The phase conversion method is to use carbonate or bicarbonate to convert calcium sulfate into calcium carbonate with lower solubility at high temperature, and then add hydrochloric acid to dissolve calcium carbo...
