International coal prices push up domestic prices before supply and demand

The energy research center of the China Energy Research Association analyzed that the coal supply and demand situation in China this year is tight and loose, and the market price is bullish. The reporter learned from the Energy Policy Research Center of the China Energy Research Associati

Electrochemical antirust paint

If the coating applied to the metal has a lower electrode potential than the metal, then in the presence of electrochemical corrosion conditions, the coating is the anode and the metal is the cathode without being corroded, which is the basis for the design of the economical protective coating
