Abstract

The invention discloses a high-hardness boiler scale corrosion inhibiting cleaning agent and a preparation method thereof. The cleaning agent comprises cetyltrimethylammonium chloride glycine betaine, carboxymethylcellulose, fatty alcohol polyoxyethylene (9) ether, disodium of 1-hydroxy ethylidene-1,1-diphosphonic acid, glycollic acid, oxalic acid, essence and water. The preparation method comprises the following steps: weighing the components according to a formula; stirring and mixing evenly; and adding the carboxymethylcellulose. The prepared high-hardness boiler scale corrosion cleaning agent is good in stability, weak in corrosivity, high in dispersion force, high in decontaminating and descaling capabilities, easy to clean, and simple and convenient to operate, has good dissolving capacity on watermarks, does not endanger the health of an operator.

Description

technical field [0001] The invention relates to a preparation method of a high-hardness pot scale corrosion inhibiting cleaning agent, which belongs to the field of cleaning agents for water treatment. Background technique [0002] The presence of calcium and magnesium ions in tap water leads to scale during use, especially the scale formed after high temperature has caused a series of adverse effects. For example, high-hardness water leads to rapid aging of towels at home, rapid fouling of water heaters and pots, etc., causing extreme inconvenience to life; various human stone diseases induce cardiovascular diseases, seriously affecting people's health, and also affecting the appearance of kitchen and bathroom porcelain Wait. Scale is also seriously affecting industrial production, especially boilers and heat exchangers, but the descaling agent used in industry, such as Chinese patent 201310359516.0 (CN103409763A) The invention belongs to the technical field of fine chemic...
