Titanium chip alkaline etching and smoothing process

Abstract

The invention discloses a titanium chip alkaline etching and smoothing process. The titanium chip alkaline etching and smoothing process includes the steps that 1, titanium chips are put into a cleaning tank; 2, the cleaning tank is lifted into an alkaline water tank with the temperature of 55-65 DEG C and washed through alkaline cleanout fluid for 5-6 minutes under the high temperature; 3, the cleaning tank is lifted into a first clean water tank and soaked for 10-15 minutes and is lifted out for being dried in the shade for 5-8 minutes; 4, the cleaning tank is lifted into an acidity tank with the temperature of 40-50 DEG C and washed through acid fluid for 3-5 minutes under the high pressure; and 5, the cleaning tank is lifted into a second clean water tank and soaked for 10-15 minutes. The titanium chip alkaline etching and smoothing process is scientific, selected raw materials are configured scientifically, pressing stirring is conducted in the alkaline cleanout fluid preparation process, existing structures of the raw materials can be changed, molecules are dispersed, recombined and fused, alkaline etching can be fully conducted on titanium chips through the cleanout liquid, alkaline etching treatment of the titanium chips can be effectively achieved, the surfaces of the titanium chips are smooth and flat, and the separated-out precipitating amount is reduced; and the situation that an etching reaction is insufficient or severe is avoided, the titanium loss and alkaline consumption are lowered, and the produced cleanout liquid is good in stability and long in service life.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy surface treatment, and in particular relates to a titanium chip alkaline light process. Background technique [0002] In the production enterprises of titanium processing, due to the unique processing technology characteristics of titanium and titanium alloys, the yield of processed materials is relatively low, generally around 50%, and a large amount of titanium scraps will be generated during the production process, so it is necessary to remove titanium scraps Recycling and utilization, cleaning, crushing, and pressing of titanium scraps after recovery. The process of cleaning the materials is to remove oil and other impurities mixed in the materials, so as to avoid these impurities from affecting the raw material composition. The existing cleaning process exists Several defects: 1. There is excessive corrosion, resulting in the loss of titanium chips and excessive consumption of alkali; ...

[0002] In the production enterprises of titanium processing, due to the unique processing technology characteristics of titanium and titanium alloys, the yield of processed materials is relatively low, generally around 50%, and a large amount of titanium scraps will be generated during the production process, so it is necessary to remove titanium scraps Recycling and utilization, cleaning, crushing, and pressing of titanium scraps after recovery. The process of cleaning the materials is to remove oil and other impurities mixed in the materials, so as to avoid these impurities from affecting the raw material composition. The existing cleaning process exists Several defects: 1. There is excessive corrosion, resulting in the loss of titanium chips and excessive consumption of alkali; 2. The stability of the cleaning solution is poor, the alkali corrosion reaction is insufficient, and oil stains and oxide films still remain on the surface of titanium chips. The surface of the alloy is not smooth enough, which will have a great impact on the follow-up work
