Abstract

The invention relates to the technical field of stainless steel flagpoles, particularly to a method for carrying out chemical nickel plating on the surface of a stainless steel flagpole. The method comprises: 1, grinding and polishing the surface of a stainless steel flagpole, and rinsing for 10-15 min with running water after the grinding; 2, removing the oxide formed on the surface of the stainless steel flagpole by using an activation solution, and carrying out water washing for 5-10 min after the activation; 3, soaking the stainless steel flagpole in a chemical nickel plating solution, carrying out chemical nickel plating treatment, and carrying out water washing for 5-10 min after the chemical nickel plating treatment; 4, carrying out passivation, wherein the obtained stainless steelflagpole is placed in a passivation solution and is subjected to passivation treatment, and water washing is performed for 10-20 min after the passivation; and 5, carrying out blow drying on the passivated stainless steel flagpole to obtain the finished product. According to the present invention, the method has characteristics of simple steps, improved work efficiency and good adhesion of the nickel plating layer, can prolong the service life of the stainless steel flagpole, and can further improve the surface beauty of the stainless steel flagpole.

Description

technical field [0001] The invention relates to the technical field of stainless steel flagpoles, in particular to a method for electroless nickel plating on the surface of stainless steel flagpoles. Background technique [0002] Stainless steel flagpoles are divided into professional electric stainless steel flagpoles, hand-operated stainless steel flagpoles, pneumatic stainless steel flagpoles, and computer numerical control stainless steel flagpoles. It is used in various factories and mines, enterprises and institutions, living quarters, stations, customs wharves, schools, stadiums, high-end hotels, city squares, etc. as a logo and is not easy to rust after processing. Iron hollow rod. It is used in conjunction with the flag to convey the visual effect of people to achieve the purpose of identification and publicity. However, the surface of ordinary stainless steel flagpoles is often prone to pitting corrosion, which seriously affects its surface aesthetics and service...
