Titanium Plate High Degree Of Stability
Titanium is a precious metal, its relative density is small, Titanium Plate high strength, high strength. Titanium and titanium plate material corrosion resistance properties, to know the titanium pump, titanium plate pump can use the occasion and the role. In a particular environment has a good corrosion resistance. Titanium pump, titanium plate pump is a strong corrosion-resistant pump, suitable for strong alkali strong acid, Titanium Plate so also called strong alkali strong acid pump. Its strong corrosion resistance, the key lies in the titanium metal materials.
Titanium and Titanium Plate Corrosion Resistance Titanium is highly stable in neutral or weakly acidic oxide solutions, for example, titanium and titanium plates at 100 ° C FeCl 100 ° C CuC12, 100 ° C HgC1: (all concentrations ), 60% AlCl2 and 100 ° C are stable in all concentrations of NaCl, Titanium Plate and many other metals in titanium are stable in 100% oxygen and 100% dioxoac, so that titanium and Titanium plates are widely used in the above solutions.
Titanium and titanium plates have high corrosion resistance in gasoline, toluene, phenol, formaldehyde, trichloroethane, acetic acid, citric acid, monochloro-ethylbenzene, etc., Titanium Plate but in the case of boiling and no inflation, Cr is not only severely corroded in the acetic anhydride-containing solution, Production of propylene oxide, phenol, acetone, chloroacetic acid and other chemical media, Titanium Plate titanium and titanium plate corrosion resistance is better than other structural materials of stainless steel Yang.
Titanium and titanium plates are also highly stable for ionic oxidizer solutions, such as 100qC sodium hypochlorite solution, oxygen water, gas (up to 75 ° C), sodium hydroxide solution containing hydrogen peroxide, Titanium Plate and the like. Titanium and titanium plate in the wet chlorine corrosion resistance than other commonly used metal, which is because the chlorine has a strong oxidation, titanium and titanium plate in wet chlorine can be in a stable passive state, in order to maintain the titanium in the chlorine Nature, need a certain amount of water. The critical moisture content is related to oxygen pressure, flow rate, Titanium Plate temperature and other factors, Titanium Plate but also with the titanium equipment or parts of the shape and size of the titanium surface and the degree of mechanical damage, therefore, the literature on the titanium in the oxygen passivation of the critical water content is inconsistent , Titanium Plate It is generally believed that the mass fraction of 0.01% to 0.05% can be used as the critical moisture content of titanium in oxygen, but practical experience has pointed out that in order to ensure the safe use of titanium equipment in oxygen, Titanium Plate sometimes the water mass fraction is 0.6% Not enough, Titanium Plate up to 1.5%. The critical water content also increases with the increase of chlorine temperature and the decrease of air velocity.
The actual operating experience also shows that titanium and titanium plate surface oxide film is destroyed, the need for a higher water content in order to make titanium and titanium plate passivation. Titanium and titanium plate in dry chlorine, even below 0 ℃ will also be a violent reaction to produce titanium tetrachloride, Titanium Plate and the risk of fire. Titanium and titanium plate in the dry chlorine in the destruction of a start, the reaction is collapse, and then add water can not prevent the progress of the reaction.
Titanium plate surface is easy to form a layer of passivation of the oxide film, the conductivity is poor, and the titanium plate in the process of easy to contaminate the oil, titanium plate will lead to decreased conductivity, resistance increases, while the coating can not Titanium plate surface close together. Therefore, Titanium Plate in order to improve the conductivity of the electrode, so that the coating and the substrate more closely, and in order to remove the titanium plate during the processing of stains, etc., Titanium Plate to ensure the electrochemical performance of the electrode and coating activity, titanium matrix need to make the necessary deal with.
Titanium plate application:
Titanium alloy is a new kind of structural material, it has excellent comprehensive performance, such as the density is small (~ 4.5 GCM - 3), high specific strength and fracture toughness than, good fatigue strength and crack propagation resistance, good low temperature toughness, excellent corrosion resistance, resistance of some of the titanium alloy of the highest working temperature is 550 oc, expect up to 700 oc.Therefore, it has been widely used in aviation, aerospace, chemical industry, shipbuilding and other industrial sectors and has developed rapidly.Light alloy, steel and other 0.2 / density (sigma) and the relationship between temperature, than strong than other metals, titanium alloy steel and nickel alloy, and this advantage can keep to about 500 oc, so some of the titanium alloy is suitable for manufacturing gas turbine components.About 80% of titanium production is used in aerospace and aerospace industries.For example, in the body structure of the American b-1 bomber, about 21 percent of the titanium alloy is used to make fuselage, wings, skin and bearing components.The body structure of the f-15 fighter plane is 7000kg of titanium alloy, accounting for 34% of the structure weight.
