Common methods are:
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.
The die casting process involves the use of a furnace, metal, die casting machine, and die.
The metal, typically a non-ferrous alloy such as aluminum, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
Metal housings for a variety of appliances and equipment are often die cast.
Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
