Introduces the basics of titanium plate
From discovery to obtain pure titanium products, which lasted a hundred years . The use of titanium really get familiar with its original true , it is the 1940s after the thing .
Geography ten kilometers thick surface strata, containing up to six thousandths of titanium , copper and more than 61 times . Just a handful of dirt from the ground , which contains a few thousandths of titanium , the world's reserves of more than ten million tons of titanium is not rare .
Result of tons of sand and gravel , both titanium and zirconium minerals heavier than the sand on the beach , they mixed in sand , the sea millions of years after panning around the clock , the heavier ilmenite and zircon sands washed together in the long coast , forming a layer of titanium and zirconium in a seam . This seam is a black sand , there are usually a few centimeters to tens of centimeters thick.
Titanium is not magnetic , nuclear submarines built with titanium magnetic mines do not have to worry about attacks .
In 1947, people began smelting of titanium in the factory . That year, the yield is only 2 tons . 1955 annual production surged to 20,000 tons . In 1972 , the annual output reached 20 million tons. Titanium and steel hardness similar and almost half of its volume with the steel weight of titanium , although slightly heavier than aluminum, its hardness than Al 2 times . Now, rockets and missiles in the universe , on a range of titanium instead of steel . According to statistics, currently the world's titanium year for astronautics , and has reached more than one thousand tons of titanium powder fine , good or rocket fuel , so titanium metal known universe , space metal .
Good heat resistance of titanium , high melting point 1725 ℃. At room temperature, titanium can be safe to lay a variety of acid and alkali solution . Even the most ferocious acid - aqua regia , nor corrode it . Titanium is not afraid of the sea , was once a titanium sink to the bottom , the next five years to take up a look at the many small animals and stick undersea plants, but he is not rusty , still shiny .
Now, people began to use titanium to make submarines - titanium submarines. Because titanium is very strong, can withstand high pressure, this submarine can sail at a depth of 4,500 meters in the deep sea .
Corrosion resistance of titanium , so the chemical industry often use to it . In the past, chemical reactor components are installed with hot nitric acid with the stainless steel . Stainless steel is also afraid that a strong corrosive - hot nitric acid , every six months , all such components should be replaced . Now, the components manufactured with titanium , although the cost of more expensive than stainless steel member , it can be used continuously years , but it is advantageous much calculation .
The biggest drawback of titanium is difficult to extract . Mainly because of the titanium compound at a high temperature capability, with oxygen , carbon, nitrogen compounds , and many other elements . Therefore , regardless of the smelting or foundry , people are careful to prevent these elements " invasion " of titanium . In the smelting of titanium , when air and water, of course, is strictly prohibited close , and even common metallurgical alumina crucible also banned, because titanium oxide would wrest from the alumina inside . Now , people use magnesium and titanium tetrachloride in an inert gas - phase separation of helium or argon , to extract titanium.
People use titanium compounds at high temperatures characteristic strong ability in steelmaking , when nitrogen is easily dissolved in the steel water, when the ingot cooling when the ingot is formed bubbles affect the quality of steel. So Riga into the molten steel workers to the metal titanium, making it the nitrification into a slag - titanium nitride , floating on the molten steel surface , so that the ingot is more pure.
When the supersonic aircraft , its wing temperature can reach 500 ℃. As with a relatively heat-resistant aluminum alloy wing , one to twenty-three Baidu will be too much , and there must be a light , and tough , and high temperature materials instead of aluminum acetate titanium just to meet these requirements. Titanium can withstand the test of minus 140 degrees , in this cold , still has good toughness of titanium rather than brittle.
The use of titanium and zirconium strong absorption of air , the air can be removed , resulting in a vacuum . For example , the use of a vacuum pump made of titanium , can only air pumped hundreds of thousands of square millionth .
Titanium oxide - titanium dioxide, a white powder , is the best white pigment , commonly known as titanium dioxide . Previously, people mining titanium , the main purpose is to obtain titanium dioxide. Strong adhesion of titanium dioxide , a chemical change is not easy , is always white . Titanium extraordinary valuable is non-toxic . Its high melting point, is used to make fire-resistant glass , glaze , enamel , clay, utensils and other high-temperature experiments .
Titanium dioxide is the most white stuff , 1 g of titanium dioxide can put more than 450 cm2 in area painted white . It is commonly used white pigment than one - lithopone whiter five times , thus modulating the best white paint pigment . Titanium dioxide pigment used in the world , more than a year to tens of tons. Titanium dioxide can be added in a paper ,Xinnuo titanium standard part the paper white and opaque , the effect is 10 times larger than any other substance , therefore , we should banknote paper and art paper plus titanium dioxide. In addition , in order to lighten the color of the plastic to make rayon soft gloss, and sometimes also added titanium dioxide. In the rubber industry, titanium dioxide is also used as a filler of white rubber.
Titanium tetrachloride is an interesting liquid , which has a pungent smell shares , will be great in the wet air white smoke - it is hydrolyzed into white titanium dioxide hydrogel . In the military , people took advantage of titanium tetrachloride, which shares a strange temper, as artificial aerosols. Extraordinary in the ocean, water vapor and more, a release of titanium tetrachloride, a white smoke as the Great Wall , blocking the enemy's line of sight. In agriculture, the use of titanium tetrafluoride people to frost .
Barium titanate crystals have such characteristics : when it changes shape under pressure , generates electricity, a power will change the shape . Thus , the barium titanate in an ultrasonic people , and it will produce a current pressure , the size of the current generated by it can detect the strength of the ultrasonic wave . Conversely , a high frequency current through it , it can generate an ultrasonic wave. Now , almost all of the ultrasonic instrument, to be used in barium titanate .Xinnuo titanium stockists In addition, there are many uses of barium titanate . For example: railway workers put it on the tracks below , to measure the pressure when the train passed ; doctors use it made of pulse logger. Barium titanate to do with underwater detectors, underwater eye is sharp , it is not only able to see the fish , but also you can see the reef , icebergs and enemy submarines under the water and so on .

Recognizing titanium , germanium , titanium bar and negative ion energy
Recognizing titanium (Ti)
Titanium is a single metal element , ranking in the first 22 chemical elements , titanium is a light texture , not rusty metal , due to the titanium ( Ti a ) soft texture, relative to its conductivity better ; " titanium " is generally used in metal jewelry reasons , because it has a light texture , non-allergic, anti-oxidation , processing and beautiful metal color, but generally claimed that the titanium industry will produce negative ions , which is the wrong idea ! Titanium metal element itself is positively charged , and will not produce negative ions, if according to the general industry said, titanium element can produce negative ions , then no titanium eyeglass frames can produce negative ions it? Hang titanium -framed glasses , you can not cure pain ? If the titanium can produce negative ions , why should an increase in germanium and titanium magnetic elements above it medical titanium bars? Therefore, the metal titanium jewelry, just simply beautiful, no allergies, no oxidation, good conductivity, excellent processing and nothing , not as general industry said exaggerate its effectiveness , just as gold has more than good ductility and conductivity of titanium resistance, this inference, gold jewelry do not hang more than titanium anion produced it?
2 . Understanding of germanium (Ge)
A. germanium metal element, belongs to non-ferrous metals , their characteristics as light texture, low ductility and brittle metal , the message in the study abroad, germanium to touch temperature of 32 degrees C or more, until the release of trace electronics , room temperature is a general metal elements, and can not play sparsely
Conduction electrons function , generally used in health jewelry , is guided by the temperature and balance the body electronics, relative, in the lack of contact surface temperature titanium pipe, or cold winter , its effect is difficult to play , so the jewelry germanium for health effect, has been in a gray area , the number of ions in the end release , currently there is no clear industry data .

The specific impact of the in-plane anisotropy titanium plate
1, the inner surface of the impact of sex on the sheet formability
Relative to the plate rolling direction is different in different properties , deformation of the cylindrical -shaped member is formed has become not axisymmetrical , there has been formed on the lug member . In addition to the emergence of the lug forming parts of the shape does not meet the requirements of ( sexual category is conformal ), the extent of allowable deformation is also a disadvantage .
Obviously, cylinder -shaped pieces of lug formed on the emergence of the cylinder is bound to shrink in the direction of the deformation of the cylinder uneven distribution of the large valleys , small lugs place, at the valley are more likely to wrinkle or scissors cut rupture. If the deformation is uniformly distributed , then this could have been avoided wrinkled or broken , or at least playing in some large deformation will occur.
Benli influence on the deformation of the lugs , except the performance outside the valley , it can also reflected in the lug direction ; performance is shaped pieces located on the lug direction , the material at the four corners of the die crack appears . This is due to the sudden wool lug width portion of the force exerted further deformation inevitably also need bigger, when it is large to a certain extent, the largest parts of the force - will die fillet crack .
Of course, non-axisymmetric parts , according to the specific circumstances of the part, select the appropriate cutting position, the nature of the use of the inner surface of the opposite sex ,medical titanium bar it becomes favorable factors , and sometimes can increase the allowable level of distortion.
The inner surface of the opposite sex conformal impact , but also the performance of the bending part . As the inner surface of the anisotropic material , ie the principal strain direction is not always the principal stress directions staff together in nature, so that the line is not bending to the plate and rolled or lateral bending pieces of the same , there has been intuitively seem should not happen wry .
The titanium surface of the opposite sex more significant adverse effects , in terms of setting is particularly prominent . Due to the different properties in different directions , even if the same molding stress , produce different rebound unloading cut , distortion of the shape of the forming member occurs , the original plane is also warped .
2, the influence of the surface of the opposite sex formability of sheet
As mentioned above ,titanium sheet the surface of the opposite sex typical performance is affected by the emergence of curvature force no longer remain flat plane . Obviously , the proper placement of wool during molding , it coincides with the curvature of the curvature formed by the surface of the opposite sex , molded parts will be beneficial to improve the degree of allowable deformation ; contrary, it will reduce the degree of allowable deformation. TCIM 1.5mm thick material such as a clear surface of the opposite sex , when the hole flanging, if the index is slightly thicker side to the opposite sex is part of the inner surface of the flange , then the limit factor than it is in the outer flange surface large 2.8%.
