Performance and practical application of titanium sheet

Since different products in different fields require different titanium sheet and titanium alloy products, they are processed into plates, rods, tubes, strips and wires, which can be provided to the majority of users in the shape of deep processing to meet the needs of different fields. Among them, titanium plates, titanium rods and titanium tubes are most widely used. The following is a general introduction to the performance of titanium plate used in the chemical industry:

IV.Surface quality

The surface of titanium plate should be bright and clean, showing the natural color of metal. The panels are allowed to be delivered on a sandblasted surface. The surface of titanium plate is allowed to be slightly dark and local water trace; Local defects are allowed, no more than half of the thickness tolerance of the scratch, indentation, pits and other defects, but the minimum thickness shall be guaranteed. The surface of titanium plate is not allowed to have cracks, peeling, oxidation, folding, metal and nonmetal inclusion and other macro defects and traces of alkaline washing. The titanium plate is allowed to clear local defects along the rolling direction, but the thickness of the plate after the removal is not less than the minimum allowable thickness. In addition, the titanium plate should not be layered.


V. Application of titanium plate

Titanium and titanium alloy has low density and high tensile strength. In the range of -253-600 ℃, its specific strength is almost the highest in the metal materials. It can form a thin and hard oxide film in the appropriate oxidizing environment and has excellent corrosion resistance. In addition, it also has the characteristics of non-magnetic, small linear expansion coefficient. As a result, titanium and its alloys were first described as important aerospace structural materials, and then extended to ship manufacturing, chemical industry and other fields, and have been rapidly developed. In particular, in the chemical industry, more and more products are used in titanium and titanium alloy products, such as petrochemical, fiber, pulp, fertilizer, electrochemistry and seawater desalination industries, as exchangers, reaction towers, synthesizers, autoclasts and so on. Titanium plate is used as electrolytic plate and electrolytic cell in electrolysis and wastewater desalination, and as tower and body in reaction tower and reaction kettle.


With the development of science and technology, the application field of titanium is becoming more and more wide, such as medical, automotive, sports, etc., out by the reaction of these themes titanium as a kind of light metals, it has the good characteristics of more and more cognitive and can be set by people, and with the fastest speed into our production applications instead of other metals, even in our body.


In some domestic household industry in order to improve the performance of existing door and class, changed in the past, only the pursuit of province industry and the low level of structure of material, low price, by is given priority to with push-pull window to performance better casement Windows of a transition, single, double, three layers, small open big fixed diversity system design, etc. At the same time in the titanium alloy door frame material, glass, spacer, sealant, etc., also want to pay attention to the selection of materials.


Titanium alloy door can be made with TC4 and titanium plate door rim, handle, spokes and reinforcing ring. Nowadays a few high-grade villa already began to use titanium alloy door, pass a long time to prove, use effect is very good, achieved the design goal that anticipates completely, added a beautiful scenery for people's life, the environment.
