What can be used for titanium or titanium alloy materials in the chemical industry?
After years of promotion, titanium and its alloys have been as a kind of excellent corrosion resistant structure materials has been widely used in chemical production. At present, the application of titanium equipment has from the initial "soda ash and caustic soda industry" extended to chlorate, ammonium chloride, urea, organic synthesis, dyes, inorganic salt, pesticide, synthetic fiber, fertilizer, and fine chemical industries, types of equipment has expanded from small, simplification to large and diverse. Chemical sector is expected, the chemical industry with titanium content of more than 1500 tons. At present, the domestic chemical titanium equipment, is the largest number of heat exchanger, followed by titanium anode and container. The results of the survey showed that 56.66% titanium heat exchanger, titanium anode (20.41%), titanium vessel accounted for 16.28%, other 6.65%. Titanium in the dosage of chemicals used in the earliest, the largest is the chlor-alkali industry, at present the national medium chloralkali plant nearly 200, most of them adopt titanium anode tank and ionic membrane electrolyzer caustic soda production, so the titanium equipment with bigger quantity.
The application of titanium in the chemical industry: Because the titanium has excellent corrosion resistance, mechanical properties and process performance, many departments are widely used to national economy. Especially in the chemical production, using titanium instead of stainless steel, nickel base alloy and other precious metals as a corrosion resistant materials. This to increase production, improve product quality, prolong the service life of equipment, reduce consumption, reduce the energy consumption and reduce costs, to prevent pollution, improve working conditions and improve labor productivity and so on has the very vital significance. Titanium has become one of the main anti-corrosion materials in chemical equipment, and in the chemical plant has established his corrosion status. As the ideal material in chemical equipment, titanium will become more and more cause the attention of engineering and technical personnel.
Titanium in the dosage of chemicals used in the earliest, the largest is the chlor-alkali industry, at present the national medium chloralkali plant nearly 200, most of them adopt titanium anode tank and ionic membrane electrolyzer caustic soda production, so the titanium equipment with bigger quantity. Soda ash also called sodium carbonate, is one of basic chemical raw materials. The method of soda ash production mainly include natural soda and salt as raw materials of the ammonia soda and soda. Whether in the process, equipment is strong corrosion media such as sodium chloride and ammonium chloride. Foreign equipment of titanium in the soda ash industry has been widely used, China since 1965, dalian chlor-alkali industry research institute, Shanghai pudong chemical fertilizer plant, alkali factory russsian company, tianjin factory, hon crane chemical plant, hubei chemical plant, alkali factory in Qingdao, and all three factory has used the new titanium, titanium equipment. Chemical industry in the inorganic chemicals, inorganic compounds, organic chemicals and chemical fertilizers, pesticides, dyes, fine chemical, chemical reagent and titanium are also widely used.
