Vad är titanpulver? Vad är användningen av titanpulver och dess renhetsindikatorer

Titanium powder is a silver gray powder that can burn in nitrogen and has a high melting point. Titanium can be hydrogenated by adding hydrogen gas under high temperature in vacuum. After inhaling a large amount of hydrogen gas, it becomes titanium hydride, which is easily brittle and can be easily made into powder. It is currently a commonly used method for mass production of titanium pulver .
The hydrogen content of titanium hydride powder is generally 4%, silver is dark gray, and hydrogen will be released under high temperature. At present, the application of this technology to make "foam aluminum" titanium hydride powder, because of the hydrogen content, needs to be made into pure titanium powder under high temperature and vacuum, and a lot of time is spent vacuuming to reduce it to titanium powder. Titanpulver är stabilt vid rumstemperatur och har stark kemisk förmåga vid höga temperaturer . Det kan kombineras med syre, kol, kväve, väte och många andra element . Pure Titanium har en sugfunktion vid höga temperaturer, så det används som ett "Suement Agent" i elektronikindustrin {{.})
Titanpulver
Titanium powder includes both titanium content and impurity content. The purity of titanium powder is related to its particle size. For products of the same specification, the smaller the particle size, the lower the purity. Generally, (coarse) titanium powder containing titanium greater than (or equal to) 99%, or close to 99%, is called a grade product (including alloy composition if it is titanium alloy powder), and those with lower purity than it are called substandard products. In grade titanium powder, except for special application requirements, it is generally required to use oxygen content to grade (the same as using titanium content), that is, the lower the oxygen content, the higher the quality. Among them, those with oxygen content less than 0 . 15% kallas ofta högkvalitativt titanpulver.
Användning av titanpulver
Titanium powder is widely used. Grade titanium powder has different uses depending on its purity and particle size. It is mainly used as a raw material for powder metallurgy to produce titanium or titanium containing alloys. Other applications include being used as an electric vacuum suction agent, a raw material for solid gong sources in electric vacuum, and a surface coating Material . Råvaror för tillsats av titanfyllmedel till plast och olika titanföreningar såsom Tib2, tenn, tic, etc .
Dihydrogenerat titanpulver kan användas som ett keramiskt och metallsvetsmedel, rent vätskällmaterial och pulvermetallurgi sintringskatalysator .
Titanpulver används också i "metalltillsatser" som ett titanmedel . Som ett tillsatsmedel kan titanpulver delas upp i titaninnehållet: ti större än eller lika med 88% ti större än eller lika med 90% större än eller lika med 92% ti större än eller lika med 95% ti större än eller lika med 97% än lika större än 78 år) Partikelstorlek är uppdelad i 40 mesh, 60 mesh, 80 mesh och 100 mesh, som kan användas som ett "titanagent" .
Extra titanium powder is mainly used as a grain refining agent for cast aluminum and as a deflagrating agent for fireworks and fireworks. Titanium powder will produce white sparks during combustion. Titanium powder is flammable when exposed to open flames and strong friction. The commonly used titanium powder for fireworks is 100 mesh for Utomhusanvändning och 200 mesh för inomhus kallt ljus fyrverkerier . ju högre renhet, desto vitare gnistan .
