Your position: Home > News > Industry trends >
  magnesium and its alloys are light weight,high strength,heat resistance,corrosion resistance and many other excellent features,known as"the future of metal",is a promising new structural materials.magnesium and its alloys not only in the aviation,aerospace industry has a very important application,and has begun in the chemical industry,petroleum,light industry,metallurgy,power generation and many other industrial sectors widely used.
 
  Another significant feature of magnesium is corrosion resistance,which is due to its magnesium and its alloys with light weight,strength,heat resistance,corrosion resistance and many other excellent features,known as the"future metal",is a The development of the future of new structural materials.magnesium and its alloys not only in the aviation,aerospace industry has a very important application,and has begun in the chemical industry,petroleum,light industry,metallurgy,power generation and many other industrial sectors widely used.
 
  Another significant feature of magnesium is corrosion resistance,which is due to its strong affinity for oxygen,can produce a layer of dense oxide film on its surface,can protect the magnesium from the media corrosion.Metal magnesium In most aqueous solutions,passivation oxide films can be formed on the surface.Therefore,magnesium in acidic,alkaline,neutral saline solution and oxidizing medium has good stability,than the existing stainless steel and other non-ferrous metals,corrosion resistance is good,even with platinum than the United States.However,if in a certain medium,can continue to dissolve the magnesium surface oxide film,the magnesium in this medium will be subject to corrosion.For example,magnesium is corrosive in hydrofluoric acid,concentrated or hot hydrochloric acid,sulfuric acid and phosphoric acid,since these solutions dissolve the magnesium surface oxide film.If oxidants or certain metal ions are added to these solutions,the magnesium oxide film will be protected,and the stability of the magnesium will increase.
 
  1.chemical industry
 
  magnesium in a variety of acid,alkali,salt medium,in addition to the above four kinds of inorganic acids and highly corrosive aluminum chloride,have a very good stability.Therefore,magnesium is the chemical industry in the excellent anti-corrosion materials,has been more and more widely used.For example,in the chlor-alkali industry,the use of magnesium anode and magnesium wet chlorine gas cooler,received a very good economic results,known as the chlor-alkali industry in a major revolution.
 
  2.Oil industry
 
  magnesium in the organic compounds,in addition to the higher temperature of the five organic acids(formic acid,acetic acid,oxalic acid,trichloroacetic acid and trifluoroacetic acid),have a very good stability.Therefore,magnesium is the oil refining and petrochemical industry in the excellent structural materials,can be used to produce a variety of heat exchangers,reactors,high pressure vessels and distillation tower.
 
  3.Metallurgical Industry
 
  magnesium is active metal,has a good breathing performance,is the steel industry in the excellent degassing agent,it can be combined in the cooling steel precipitation of oxygen and nitrogen.Adding a small amount of magnesium(<0.1%)to the steel makes the steel tough and elastic.magnesium is also an important alloy additive for steelmaking,aluminum blending and other industries.magnesium has a superconductivity and is a common superconducting material.In addition,magnesium in metal ions containing acidic solution has a good stability,so magnesium in the hydrometallurgical industry,such as copper,nickel,cobalt,manganese and other non-ferrous metal electrolytic production,has a very wide range of applications.
 
  4.Fertilizer industry
 
  Urea is an important chemical fertilizer,in the production process of urea,ammonia,ammonium carbamate and their mixture,under high temperature and high pressure conditions,strong corrosion,the use of magnesium instead of stainless steel equipment life greatly increased maintenance time is greatly reduced.So the current production of urea in the main equipment are used magnesium.
 
  5.Desalination and shipbuilding industry
 
  magnesium is resistant to seawater corrosion better than all other metals,both in the static or high-speed flow of magnesium in the sea have a special stability.Therefore,magnesium is the ideal material for desalination plants.magnesium in this area will be more and more applications.magnesium is resistant to seawater and marine air corrosion is strong,and strong,light weight,is the ideal shipbuilding industry structural materials,has been widely used in various ships,deep water submarines in many components.
 
  6.Power industry
 
  magnesium has good stability in many corrosive hot water containing chlorides,sulfides and so on.Therefore,magnesium has been used as a cooling pipe for heat exchangers in a large number of thermal power plants.With thin-walled magnesium tube to replace the copper-nickel alloy tube,not only greatly improve the service life,but also greatly reduces the maintenance time,the economic effect is very significant.
 
  7.Paper and textile industry
 
  magnesium on chlorine dioxide,chlorous acid,chlorite and other bleach has a special anti-corrosion properties.Therefore,magnesium in the textile printing and dyeing industry,paper industry bleaching equipment has an important application.For example,the use of magnesium sub-machine used to make good results.At the same time,there are synthetic fibers and other industries used as spinneret.
 
  8.Other aspects
 
  magnesium can resist the body's corrosion,and harmless to the human body.So it can be widely used in the medical and pharmaceutical industry sectors.magnesium has a good suction performance,but also in electronic vacuum technology and high vacuum technology has a wide range of applications.
