How to store and transport titanium powder?
Titanium powder is flammable and explosive dangerous goods, usually packed in iron drums. In order to prevent moisture absorption and oxidation, the grade titanium powder should be evacuated and packaged in a composite plastic bag (or aluminum foil plastic composite bag) immediately after processing, and then put into an iron barrel. When transporting, it must be handled with care to avoid shock. Storage should be selected as a separate dedicated warehouse.
The purity of titanium powder is related to its particle size. The smaller the particle size, the lower the purity of the same specification. Usually, the (coarse) titanium powder with titanium content of not less than 99% or close to 99% is called grade product (in the case of titanium alloy powder, the alloy component should be included); Those with lower purity than it are called equivalents. In grades of titanium powder, in addition to special application requirements, the oxygen content is generally required to be graded. That is, the lower the oxygen content, the higher the quality. Among them, those with an oxygen content of less than 0.15% are often referred to as high-quality titanium powders.
Titanium powder particle size can be divided into 4 grades, the particle size in l000-50um is coarse powder; 50-10um is fine powder; 10-O. 5 small is micro powder; less than 0.5um is ultra-fine powder. The particle shape of titanium powder is spherical, polygonal, spongy and flaky, and its particle shape is related to the preparation method.
With the development of science and technology and the expansion of titanium powder application fields, the requirements for the quality of titanium powder are constantly improving. The oxygen content of many high-quality titanium powders has reached about 0.1%. The demand for high-quality titanium powder in the international market is increasing.
