Purification Method 1. The charge activated chloride: activated carbon adsorption air containing mercury, mercury chloride and mercuric chloride and generated.
Hg+Cl 2 →HgCl 2 ↓
The purification efficiency of this method can reach 99.9%.
2. Manganese dioxide absorption method: Natural pyrolusite can absorb mercury vapor strongly, and can also absorb fine mercury beads in full liquid.
MnO 2 +2Hg = Hg 2 MnO 2
Hg 2 MnO 2 can form mercury sulfate when sulfuric acid is present:
Hg 2 MnO 2 +4H 2 SO 4 +MnO 2 =2HgSO 4 +2MnSO 4 +4H 2 O
The absorption efficiency of pyrolusite can reach 95-99%. In addition, the mercury-containing waste gas can be purified by a water rinsing method.
2. Ceramic heating elements, control the temperature of each
heating element separately, suitable for the product of complex structure.
3. The area of lower mould is closed, blowing after the material
being heated and soft which can avoid material sinking, can insure the uniform
thickness of finished good.
4. Lower mould is driven by big cylinder, rack positioning can
insure running smoothly.
5. Large air cooling motor which can insure finished good rapid
cooling.
6. Equipped with water cooling system, can further rapid cooling.
7. Double-furnace(optional), can heat the material on two
surfaces, especially suitable for thick material(5-10mm).
