preparation example Construction

[0017] The preparation method of the cleaning agent of the present invention is as follows: after dissolving the cleaning agent in deionized water, the cleaning agent is continuously stirred for 1-2 hours under 50-1200 rpm magnetic or mechanical stirring. In order to avoid defects such as white spots or white spots that may be caused by uneven mixing of the cleaning agent, it is preferable to dissolve the components of the cleaning agent in deionized water and then mix them with each other.

[0018] The present invention also provides a stainless steel cleaning method, the method is ultrasonically cleaning the stainless steel workpiece in a cleaning agent, and the cleaning agent is the cleaning agent described in the present invention.

[0019] According to the stainless steel cleaning method provided by the present invention, preferably, the temperature of the ultrasonic cleaning is 70-90° C., and the ultrasonic time is 5-10 minutes. Ultrasonic vibration is used to remove oil...

Abstract

The invention belongs to the field of surface treatment, and relates to a stainless steel cleaner. The cleaner comprises a nonionic surfactant, an anionic surfactant, a complexing agent, a degreasing agent and deionized water, wherein the degreasing agent is one of amide, and a mixture of amide and hydramine. An environmentally-friendly cleaner comprising the amide or the hydramine, a composite surfactant and the like removes grease under the alkalescent condition, and has good cleaning effect due to the permeation effect of the composite surfactant on the grease and an oxide layer. The invention also relates to a stainless steel cleaning method. The stainless steel cleaner and the stainless steel cleaning method are widely applied to the treatment of various stainless steel surfaces.

Description

technical field [0001] The invention relates to a cleaning agent group and a method for cleaning stainless steel using the cleaning agent. Background technique [0002] Stainless steel has excellent corrosion resistance and wear resistance. With the improvement of people's living standards, the demand for stainless steel products for civil products is also expanding, and it is constantly developing towards decoration. [0003] Physical vapor deposition (PVD) coating can give metal a special ceramic texture and color, and it is also an environmentally friendly surface treatment method for metal parts. Now more and more stainless steel products have to be PVD coated to obtain stainless steel products with ceramic texture. [0004] At present, there are many cleaning agents for oil removal, wax removal, and rust removal on the market, but most of them are strong oxidants such as potassium permanganate, potassium dichromate, or strong acids such as high-concentration sulfuric ...
