Environment-friendly magnesium alloy passivating equipment

Abstract

The invention relates to environment-friendly magnesium alloy passivating equipment. The equipment comprises a main body, and a moving device, a grinding box, a first valve, a dust removing mechanism,a passivating mechanism and two grinding mechanisms are arranged in the main body; each grinding mechanism comprises a lifting unit, a telescopic unit, a second motor and a grinding wheel; the passivating mechanism comprises a passivating box, a liquid inlet pipe, a purification pipe, a liquid discharging pipe, a second valve, a moving unit and a heating unit. According to the environment-friendly magnesium alloy passivating equipment, through the grinding mechanisms, the magnesium alloy passivating equipment can remove the magnesium oxide on the surface of the magnesium alloy through grinding, so that the situation that due to the magnesium oxide, a passivating agent can be difficultly adhered to the surface of the magnesium alloy is prevented, then the passivating effect of the magnesium alloy is improved; and moreover, through the passivating mechanism, the magnesium alloy passivating equipment can clean up a chromate passivating agent left on the surface of the magnesium alloy subjected to the passivating treatment, and can dry a passivating agent removing liquid on the surface of the magnesium alloy, so that the harm caused by hexavalent chromium which exists in the chromatepassivating agent to the environment and the human health is prevented.

Description

technical field [0001] The invention relates to the field of new material processing equipment, in particular to an environment-friendly magnesium alloy passivation equipment.

Problems solved by technology

Its characteristics are: low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, good corrosion resistance to organic matter and alkali, mainly used in aviation, aerospace, transportation, Chemical, rocket and other industrial sectors, but the electrochemical activity of magnesium is too high, all acidic plating solutions will cause rapid corrosion of the magnesium matrix, or the replacement reaction with other metal ions is very strong, the coating after replacement is very loose, so it is necessary to Passivation treatment of magnesium alloy

[0003] Magnesium oxide formed on the surface of magnesium alloy is very easy to react with air, and magnesium oxide will seriously affect the adhesion of the coating, but the existing magnesium alloy passivation equipment generally cannot effectively remove the magnesium oxide on the surface of magnesium alloy, making it difficult for the passivation agent to adhere On the surface of magnesium alloy, the passivation effect is reduced. Not only that, the passivation agent used in the existing magnesium alloy passivation equipment is generally chromate passivation agent, but there is hexavalent chromium in the chromate passivation agent, which will cause Harmful to the environment and human health
