Q:Can we import scrap tanks and other scrap metals from Russia?

Scrap metal can be, scrap tanks do the relevant documents, you can also.

Q:What is the sign of PD? What are the signs of other precious metals?

Platinum (Pt) - acid ferric chloride at room temperature. But it can be slow, aqua corrosion, hydrochloric acid only adding oxidant to the corrosion of platinum, platinum in hydrobromic acid corrosion at room temperature under high temperature corrosion can platinum halogen, molten potassium (sodium) to platinum platinum dissolved in strong corrosion. Boiling aqua regia and sulfuric acid.Platinum (PD) attracts organic vapors. Carbon and carbide affect physical and mechanical properties, so contact with this material should be avoided in the manufacture and use of platinum palladium and its alloys

Q:Why can't aluminum and other metals be heated in an electromagnetic oven?

Induction cooker as a new cooker in the kitchen market. It breaks the traditional way of cooking fire by magnetic field induced current (also known as eddy current) principle of heating, the electromagnetic oven is through the electronic circuit board part produces alternating magnetic field, when the iron pot is placed at the bottom of the furnace surface, the current pan cutting in the bottom of the pot and the alternating magnetic field generated by the alternating metal part (i.e., eddy current) eddy making pot iron molecular speed ofnonlocalized, molecular collision, friction heat (the heat: electromagnetic oven cooking from the bottom of the pot instead of the cooker heating conduction to the pot, so the thermal efficiency than the efficiency of all cooking utensils were nearly 1 times higher) make the equipment itself to high-speed heating, for heating and cooking food, so as to achieve the purpose of cooking. With fast heating, high thermal efficiency, no fire, no smoke, no harmful gas, due to the advantage of heat radiation, small volume, good safety and beautiful appearance of the surrounding environment, can complete most of the tasks of family cooking. Therefore, in the more popular countries of the electromagnetic stove, people call it "the God of cooking" and "the green stove".Main composition of electromagnetic oven

Q:What does "productive scrap metal recycling" mean?

Productive scrap metals include:(I) scrap iron and steel;(two) waste alloy steel(three) scrap non-ferrous metals;(four) waste rare metals

Q:Are iron and steel nonferrous metals?

Iron, manganese and chromium are ferrous metals, and other metals are nonferrous metals.More importantly, both non-ferrous metals and ferrous metals are within the limits of purity. Steel is an alloy of carbon and iron, a mixture, an alloy, and not a metal.What we commonly call iron and steel is steel. It is not a non-ferrous metal.

Q:What is a metal without magnetism?

If you want to be sure of what metal elements it is, if you want to be more reliable, it is recommended to do a chemical element analysis.

Q:What kind of metal is the ordinary key made of?

According to the unearthed cultural relics and the written records, the ancient lock works on the elastic force of two plate like springs. Until now, this spring was still in use.

Q:The characteristics of metal mesh curtains and the manufacturing process of metal mesh curtains

The metal mesh curtain is made of aluminium magnesium alloy wire, copper wire, stainless steel wire and so on. The net curtain surface can be the original color of the metal, and can also be processed into bronze, gold and other metallic colors. The curtain can be used for advanced buildings, luxury living room screen decoration, star hotels, luxury dance halls, high-rise office buildings, interior and exterior decoration, lighting mapping, showing a magnificent effect.

Q:Does the heavy metal solution dilute with the support electrolyte?

Plating (Electroplating) process is to use the principle of electrolysis plating on a thin layer of metal or alloy in some metal surface, is the process of making the surface of metal or other material parts attached to a layer of metal film by electrolysis so as to prevent metal oxide (rust), improve wear resistance, electrical conductivity, reflection, corrosion resistance (copper sulfate) and improves the appearance effect. The outer layers of many coins are also electroplated.

Q:Are there any metals that do not conduct electricity?

From the chemical properties of metal metal bonds, and non metals are connected by ionic or covalent. From physical properties, general metal conductive, with metallic luster, malleable. And most of them are only solid mercury is a liquid at room temperature. Instead of metal is mostly non metal insulator, only a few the conductor (carbon) or semiconductor (silicon). But due to the rapid development of science and technology, the difference between them is becoming more and more obvious. The development of nanotechnology, the metal and nonmetal distinction between more and more small.
