In the hydrometallurgical process, due to the equipment's contact with alkali, acid and various corrosive gases, smoke and dust, traditional aluminium alloys, acid-resistant stainless steel and other materials cannot meet the needs of the production process, which limits the development of hydrometallurgy. The use of titanium equipment is of great significance in improving production efficiency, solving common phenomena such as running, popping, dripping and leaking in hydrometallurgy, and reducing environmental pollution.
(1) Aplikasi of titanium equipment in electrolytic nikel production
In the production of electrolytic nickel, the equipment comes into contact with solutions containing high acid content and active ions. Titanium has excellent corrosion resistance, making it an ideal material for manufacturing electrolytic nickel equipment.
Berbanding dengan tahan karat keluli ibu plat, cathode mother plates in electrolytic nickel production have better economic effects and superior performance. For example, the deposited nickel skin is not easy to stick to the plate, is easy to peel off, the peeling rate is increased, and the initial electrode piece of the titanium mother plate is smooth. , good rigidity, uniform current density during electrolysis, etc. In addition% 2c heaters, pumps, valves, etc. in electrolytic nickel production equipment also use a large amount of titanium materials.
(2) Aplikasi of titanium equipment in electrolytic copper production
The cathode rollers of electrolytic copper production equipment originally used steel cathode rollers. Due to the corrosion of the electrolyte, pitting corrosion occurred on the surface of the rollers, which affected the quality of the copper foil. Regular grinding of the rollers also wasted human and financial resources. These problems are solved by using titanium rollers. In addition, most of the heaters and cathode motherboards used in electrolytic copper production are made of titanium.
(3) Hydrometallurgy of other metals
Titanium equipment is also used in the smelting of cobalt, zinc, aluminium, mercury, etc., and the purification of tungstic acid. The main equipment in the metallurgical industry includes electrolyzers, reactors, washing towers, heat exchangers, stirrers, evaporation devices, dust collection devices, etc. , have achieved significant benefits. Titanium pumps are also used abroad to transport chloride, sodium chloride, kalium klorida dan dilute hydrochloric acid. The life of the pump is 5-20 times longer than that of cast iron pumps or stainless steel pumps, and the liquid loss is reduced by three-fifths. The titanium storage tank in the chlorination workshop The tank can be used for {{}} years, while the steel storage tank can only be used for 2 months.
