The difference between traditional surface treatment technology and modern treatment technology:

Dalian Metal Surface Treatment: Traditional surface treatment technologies have three major worldwide challenges: high pollution, high energy consumption, and low workpiece quality. During the treatment process, exhaust gas pollution, dust pollution, and solid waste pollution can be generated. Severe dust and gas pollution in the processing workshop leads to a very harsh working environment for workers, and the dust and gas discharged outside the workshop is also one of the important sources of atmospheric pollution. In surface treatment and processing enterprises, if environmental protection processes such as alloy catalytic fluid are not used, sealing, isolation, and negative pressure operation measures should be taken for equipment that generates fugitive dust or harmful gases.

After collecting waste gas and dust, each surface treatment enterprise should conduct a comprehensive analysis based on factors such as the amount of waste gas generated, the composition and nature of pollutants, temperature, pressure, and so on, and select a mature and reliable waste gas treatment process route. For low concentration organic waste gases that have recovery value, adsorption technology should be used; When there is no recovery value, adsorption concentration combustion technology, regenerative thermal incineration technology, biological purification technology, or plasma technology should be used. Aluminum alloy oxidation colors generally include natural color and sky blue.

Anodic oxidation is carried out under high voltage, which is an electrochemical reaction process; Conductive oxidation does not require electrification, but only immersion in liquid medicine. It is a pure chemical reaction. Anodic oxidation takes a long time, often tens of minutes, while conductive oxidation only takes a few tens of seconds. Electroplating is the process of using electrolysis to deposit metal or alloy on the surface of a workpiece to form a uniform, dense, and well bonded metal layer, which is called electroplating. A simple understanding is a change or combination of physics and chemistry. In the past, the cleaning technology used by outsourcing factories often turned black after oil removal due to the carbon attached to the surface of copper parts, affecting the beauty of the product.

However, after cleaning with a two in one oil and rust removal purification solution, the sample has neither fog marks nor residues, and is clean and transparent, retaining the original color of the product material. A typical example is plastic surface treatment, which is now widely used in many fields such as electronic products, automobiles, sanitary ware, lamps, household appliances, and so on. With the further development of engineering plastics and composite material technology, there will be more and more structures made of plastics. To obtain the effects and functions of metals on the surfaces of these materials, only surface treatment technology is the appropriate manufacturing technology. To save energy, countercurrent rinsing technology can be used for this second water wash.

Deionized water washing shall be used for the next water washing after phosphating to ensure the quality of phosphating. The surface adjustment treatment before phosphating can eliminate the non-uniformity of surface state caused by alkaline degreasing. The surface (interface) of the part pretreated with titanium phosphate solution (colloidal titanium) can generate potential and activate the surface, thereby generating a large amount of free energy, increasing the number of phosphating crystal nuclei, making the grains finer, and accelerating the film forming reaction. Remove the oil stain from the surface of the workpiece.
