A processing method that can reduce the working procedure after the workpiece is galvanized

Abstract

The invention discloses a treatment technological method with procedures being reduced after galvanization of a workpiece. The treatment technological method comprises the following specific steps that 1) the workpiece after the galvanization is finished is integrally and completely put in a clear water tank in which water flows rapidly and is in a normal temperature state through an acid pickling hanging belt, and the workpiece vertically rises and falls for three to four times, thereby completing an initial water washing procedure; and 2) the workpiece after the initial water washing procedure in the step 1) is raised from the clear water tank in the step 1) and is put in another clear water tank in which water flows slowly and is in a normal temperature state, and the workpiece vertically rises and falls for three to four times, thereby completing a secondary water washing procedure. (1) With the adoption of the treatment technological method, 17 procedures of a traditional technology is simplified into 11 technological processes, and by optimizing the technological processes, the production efficiency is improved substantially, the material consumption is reduced, and the purposes of energy conservation and emission reduction are achieved; and (2) by employing the physics ultrasonic principle and high temperature soaking, the cleaning effect of the workpiece is improved, and the quantity of acid-alkali substances in gaps of the workpiece is reduced to the lowest, so as to meet the electroplating requirements.

Description

technical field [0001] The invention relates to the technical field of post-galvanizing treatment technology, in particular to a treatment method for reducing the number of steps after galvanizing a workpiece. Background technique [0002] The traditional galvanizing subsequent treatment process is: galvanizing→water washing→water washing→hot water washing→ultrasonic→water washing→irradiation→water washing→ultrasonic→water washing→trivalent chromium passivation→water washing→water washing→water washing→ultrasonic hot water washing→water washing→compressed air blow dry; [0003] The traditional galvanizing post-treatment process has many steps, which increases the loss of equipment, the use of coal and the waste of water resources, which makes the production cost higher, cannot meet the production demand, and cannot achieve the purpose of energy saving and emission reduction. Contents of the invention [0004] The purpose of the present invention is to provide a treatment ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a treatment process method that can reduce the working procedure after the workpiece is galvanized, so as to solve the problem that the existing traditional galvanizing follow-up treatment process has many steps in the treatment process, increased equipment loss, coal burning, etc. The use of water resources and the waste of water resources make the production cost higher, which cannot meet the production demand and fail to achieve the purpose of energy saving and emission reduction.
