Low speed large capacity centrifuge corrosion performance analysis

On low speed large capacity centrifuge the other information please visit http://www.shlxj.com.cn/ for more details.
Low speed large capacity centrifuge using brushless frequency motor Ding moment, maintenance free, lifting speed, the import of fluorine free compressor unit, precise temperature control. Also has the automatic door locks, speeding, over temperature automatic maintenance, not balanced maintenance, the fuselage uses the high quality steel structure, safe and reliable. Can be generated for various gel bubble at different temperatures, compressed purge. The rotor and can be based on user needs consumption adaptation of different shapes and specifications. Low speed large capacity centrifuge is widely applied in the blood, pharmaceutical factory, biochemistry, biological products and other consumer research unit, is a blood separation, protein precipitation, the ideal equipment to collect the cell separation.
In the low speed large capacity centrifuge use, corrosion problem of centrifuge rotor is always influence turned life, influence of centrifuge using an important element of peace. Head of manufacturing common use of high strength, light weight aluminum alloy. Low speed large capacity centrifuge aluminum alloy in its price is low, easy, easy processing characteristics of source. Widespread use of centrifuge especially in speed is relatively low in. But the alloy aluminium is a metal elements in a chemical vivid is very strong, copper, magnesium, zinc and other alloy elements can make aluminum reinforced aluminum alloy, so the data often contain copper, zinc, magnesium, which strengthen effect of copper, the largest, deterioration of corrosion resistance influence is most important. Low speed large capacity centrifuge electrochemical aluminum characteristics, the equilibrium potential is very low, in the range of PH wide may attack hydrogen corrosion. The oxygen in the air and other harmful gases, corrosive chemical agent vapor environment, copper, zinc and other elements of the alloy materials will produce a series of redox, charge variation, atomic precipitation produce lattice corrosion alloy destruction. Low alloy metal material crystal lattice changes of large capacity centrifuge will cause stress intensity landing. This is a kind of alloy metal corrosion in air under natural conditions to produce this kind of corrosion, impact will gradually accumulate and increase over time, thus affecting the service life of rotor.
