Titanium alloy packing barrel manufacturing technology

Abstract

The invention provides a titanium alloy packing barrel manufacturing technology. The surface of a titanium barrel body is subjected to nylon wheel rough polishing, felt wheel finishing polishing and yellow cloth wheel super-finishing polishing in sequence, there are no defects, such as scratches, blisters, piebald and bastard cut, on the surface of the titanium barrel body, a full-mirror effect isachieved, the uniformity of the polishing quality is improved, the technical steps are simple, the technology is easy to implement, and the polishing efficiency is high. For the treatment of the internal surface of the titanium barrel body, the internal surface is subjected to cleaning by using a cleaning solution, washing with RO ultrapure water, drying, electrolysis by using an electrolytic polishing solution and washing with RO ultrapure water in sequence, it is ensured that the impurities and oil contaminations on the internal surface of the titanium alloy barrel body are removed thoroughly, and the aim that the surface is super clean is achieved; afterwards, through oxidation treatment, a dense oxidation layer is naturally formed on the internal surface of the titanium alloy barrel body, the corrosion resistance of the titanium barrel is improved, and the service life of the titanium barrel is prolonged.

Description

technical field [0001] The invention belongs to the technical field of titanium barrel manufacturing, and in particular relates to a manufacturing process of a titanium alloy packaging barrel. Background technique [0002] Due to its good specific strength, corrosion resistance and high temperature resistance, titanium alloys have been more and more widely used in aerospace, biomedicine, ships, electronics and other fields. Most liquid chemical products have a pungent smell or are easy to volatilize, and generally need to be stored or transported in packaging barrels. Most of the current packaging barrels are stainless steel packaging barrels. For more expensive liquid crystal products, titanium alloys are generally used. Packaging barrels are used for storage and transportation. Due to the relatively high price of liquid crystal products, the matching titanium alloy packaging barrels also need to be manufactured in strict accordance with the specifications, especially for t...

Problems solved by technology

Most liquid chemical products have a pungent smell or are easy to volatilize, and generally need to be stored or transported in packaging barrels. Most of the current packaging barrels are stainless steel packaging barrels. For more expensive liquid crystal products, titanium alloys are generally used. Packaging barrels are used for storage and transportation. Due to the relatively high price of liquid crystal products, the matching titanium alloy packaging barrels also need to be manufactured in strict accordance with the specifications, especially for the outer and inner surfaces of titanium alloy packaging barrels. Well, it will not only pollute the quality of the liquid material stored inside, but also greatly reduce the corrosion resistance of the titanium alloy packaging barrel and reduce the service life of the titanium alloy packaging barrel

The invention patent with application number 201810069034.4 discloses a mirror polishing method for the surface insulation of a titanium alloy rotating body. Rough grinding, rough polishing and fine polishing are carried out on the surface of the rotating body to achieve a mirror effect on the surface of titanium and titanium alloys. However, this method uses a variety of processing equipment, polishing wheels and wax for multiple polishing. Processing costs, reducing polishing efficiency
