I. Introduction Kai Union brand stainless steel pickling KM0203, is the latest development of a new type of fast pickling products, stainless steel parts for any rust forming in the production, assembly, welding, etc. produced during welding spots, black and Play yellow solid oxide can be quickly cleared and transformed into silver, mainly for SUS300 austenitic stainless steel in a variety of series. Clear all types of stainless steel surface with oil, scale, welding spots and rust phenomenon, a uniform silver-white passivation film, to improve corrosion resistance of the workpiece. Second, characteristics and advantages: 1, integrated pickling and passivation; making the process more simple, more cost savings; 2, process is simple, requires no special operating environment, non-toxic low corrosion, general plastic containers can be used, equipment Easy configuration 3, this product does not contain the traditional formula of nitric acid and hydrochloric acid, in order to eradicate the pollution due to the pickling process produces nitrogen oxides caused, improve the environment of the workpiece; 4, long life, can be recycled reused Range of application: ? This product is suitable for 201,202,304,316 and silver 304L and other surface passivation of austenitic stainless steel, used in various types of precision metal, semiconductor components, pressure vessels, and more successful experience of the application of this product will become the List of well-known electrical facilities passivation of stainless steel parts suppliers. Japan rigorous testing by accredited testing organizations, mature applied passivation of stainless steel components in food. The use of methods: * Keep the product with water by 1: 4 dilution after use, room temperature, soak for 5 to 15 minutes, will completely remove surface dirt, was silver in white uniform, then rinse with clear water , such as lime or alkaline rinse After a certain need to use tap water to wash away the surface of lye, a yellow surface to avoid water spots.
