Abstract

The invention discloses a stainless steel cleaner which comprises the following components in percentage by weight: 10-20 percent of phosphoric acid, 1-5 percent of citric acid, 0.2-1.5 percent of ananion surface active agent, 0.1-1 percent of a non-ionic surface active agent, 1-5 percent of a benzotriazole corrosion inhibitor, 0.1-0.2 percent of a de-foaming agent and 50-80 percent of deionizedwater. The stainless steel cleaner disclosed by the invention is mainly used for cleaning stainless steel equipment, is non-toxic and non-flammable and can form a passivation membrane on the stainlesssteel surface while cleaning, thereby better protecting the equipment.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for stainless steel and a preparation method thereof. Background technique [0002] Industrial equipment and components such as modern chemical and energy use a variety of structural materials. In addition to the common use of carbon steel, a large number of stainless steel and some materials such as titanium, copper, and aluminum are used. During the operation of various condensers, heat exchangers, filters, reverse osmosis and other equipment, due to the change of water quality and temperature difference, it is easy to cause fouling of the inner tube, which greatly reduces the heat exchange and filtration efficiency of the equipment, resulting in Downtime. Traditional methods are generally manual cleaning, high-pressure water washing and chemical cleaning, which not only have poor cleaning effect, but also easily cause corrosion and damage to metal pip...
