[Chinese aluminum industry network] 5052 aluminum alloy is a key product of the 5 series aluminum alloy, belonging to the 5 series magnesium aluminum alloy, wherein the content of magnesium is between 2.2% and 2.8%, belonging to the 5 series low magnesium alloy, and the heat treatment can not be strengthened. Medium strength, good corrosion resistance and weldability, ease of forming and other advantages. 5052 aluminum alloy annealed state of good plasticity, high work hardening rate, low hardness in the hard state, magnesium is a strengthening element of 5052 aluminum alloy, there is a certain solid solution strengthening effect, when the hardening rate of the alloy is increased, the alloy strength changes significantly.
The 5052 aluminum alloy plates were: silicon 0.25, copper 0.10, magnesium 2.2-2.6, zinc 0.10, manganese 0.10, chromium 0.15-0.35, iron 0.40, and aluminum as the balance. The 5052 aluminum sheet has a tensile strength of 170-350 MPa and an annealing temperature of 345 degrees Celsius. The mechanical properties of the 5052 aluminum sheet will be different under different work hardening and heat treatment conditions. Compared with the 1 series pure aluminum plate, the 5052 has a tensile strength of 210-230, and the hardness is 100% higher than that of the 1 series representative alloy 1060. At the same time, the elongation rate is also increased by 12-20%. Due to the effect of the alloy elements, the 5052 aluminum plate The corrosion resistance is more pronounced.
In general, in the production, 5052 aluminum alloy surface can not appear cracks, corrosion spots and traces of nitrate salt, the surface does not allow local mechanical damage such as skin, bubbles, the depth of the defect can not exceed 0.5mm, defect area It does not exceed 5% of the total area of ​​the sheet. Other requirements are negotiated between the purchasing company and the manufacturer.
From the perspective of applications, 5052 aluminum alloy is widely used in some industries such as machinery, automobiles, and accessories. With the development of various industries, the demand for 5052 aluminum alloy sheet is also increasing. It is a large number of aluminum processing manufacturers 5 series aluminum "Star Products.
1. Product introduction
Coal-based Column Denitrification Column Activated Carbon is cylindrical black particles. It has many characters, such as high porosity, high sulfur capacity, high desulfurization efficiency, large surface area, light weight, strong adsorption capacity, wear resistance, good water resistance, low air resistance, easy regeneration, not easy to break under high pressure etc. It is a commonly used in adsorbent.
2. Adsorption purification principle and process
Coal-based denitrification Activated Carbon is divided into large pores (pore size greater than 50nrrt), the middle hole (pore size between 2 ~ 50nm) and micro-pore (pore size less than 2nm) three categories.
The denitrification activated carbon is by active carbon`s adsorption and catalytic activity of activated carbon. The strong catalytic effect of the active carbon for sulfur dioxide in gas, and a small amount of Oxygen in the oxidation reaction, the reaction of elemental S adsorbed the surface of activated carbon. When activated carbon desulfurization agent the adsorption reaches saturation, the desulfurization efficiency decreased obviously, it must carry on the regeneration. The regeneration of active carbon adsorption depends on the material, sulphur began to melt under atmospheric pressure is 190 degrees, 440 degrees Celsius will sublimate into gas, therefore, the general use of superheated steam temperature of about 450-500 degrees Celsius for the regeneration of activated carbon desulfurization agent. When the desulfurization agent reach high temperature, the elemental sulfur separate out activated carbon, the precipitation of sulfur into sulfur recovery pool, water cooled to form solid sulfur.
