Working principle of zero discharge system of electroplating wastewater: the zero discharge system of electroplating wastewater mainly uses membrane separation technology. Because membrane separation technology has the advantages of low energy consumption, no phase change, no pollution, and high separation efficiency and concentration multiple, appropriate membrane separation is used to concentrate the rinse water of electroplating solution, and the concentration multiple can reach 100 times (in volume). The concentrated solution after membrane separation is properly

Radiation method: connection solution. Generally, the operating pressure range is 70-120kPa. The greater the radiation pressure is, the greater the contrast of the machine's decontamination power in the degreasing process is. The role of radiation in the process of low-pressure radioactive degreasing is decisive. Radiation has a good removal effect on non-metallic nominal dirt, carbon particles, quartz sand and other granular dust. Inorganic solution of various groups

The production of illegal electroplating equipment manufacturers has caused great harm to the environment and the health of the surrounding people due to the imperfect pollution treatment mechanism. First, air pollution: strong acids, strong alkalis, salts, organic solvents and other chemicals should be used in large quantities in electroplating production, which will emit a large amount of toxic and harmful gases in the process of operation. For example, hydrofluoric acid smokes in the air, and the steam is highly corrosive and toxic

What are the common types of power supply for electroplating equipment? Common switching power supply has the following five types: 1. DC generator DC generator belongs to the initial electroplating power supply. It has the advantages of stable switching power supply and great load working capacity, but it has large energy consumption, low efficiency, large noise and poor rationality. Large and medium-sized electroplating process workshops are rarely used and can only produce temporarily

Not all positive ions of metal materials in electroplating equipment can accumulate from the solution. If the adverse reaction of hydrogen ion recovery to hydrogen on the cathode plays a key role, the positive ions of metal materials cannot be dissolved on the cathode. According to the test, the probability of positive ions of metal materials electrodepositing from the solution can obtain the necessary regularity from the periodic table of elements, Anodizing divided into soluble anodes
