Spring phosphatization process

Abstract

The invention discloses a spring phosphatization process, which is characterized by comprising the steps of: 1) soaking a spring in a 20%NaCaco3 solution at 60-80DEG C for 15min; 2) taking the spring out, and rinsing the spring clean in 60-80DEG C hot water; 3) at room temperature, soaking the spring in a 20% hydrochloric acid solution for 15min; 4) taking the spring out, and immediately rinsing the spring clean in 80DEG C hot water; 5) putting the rinsed spring into a phosphatized container, pouring a well prepared phosphatization solution into the container to submerge the spring completely, turning on heating equipment, heating the phosphatization solution to 88-95DEG C for 8-15min, and rinsing the phosphatized spring with clean water to obtain a grey brown spring; and 6) after phosphorization, conducting filling and sealing treatment on the phosphate film, putting the spring into the filling solution, and performing heating to 90-98DEG C for 5-10min, taking the filled spring out of the filling solution and conducting rinsing, drying or airing the spring, and soaking the aired spring into TECH1300 antirust oil for 1min, then taking the spring out and performing airing. The phosphatization process is simple, and the spring phosphatization effect is better.

Description

technical field [0001] The invention relates to a spring phosphating process. Background technique [0002] At present, the spring phosphating process is complex and there is no uniform standard, resulting in uneven quality of phosphating springs. Many repeated processes also lead to low production efficiency, increase the labor burden of workers, and make the market competitiveness of products low. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a spring phosphating process, which is simple and has a better spring phosphating effect. [0004] To achieve the above object, the invention provides a kind of spring phosphating process, it is characterized in that, comprises the following steps, 1) spring is soaked in the 20%NaCaco3 solution of 60-80 degree Celsius 15 minutes; 2) spring is taken out, in Rinse in hot water at 60-80 degrees Celsius; 3) Soak the s...
