What electrophoretic equipment is included in a complete electrophoretic coating production line
The so-called electrophoretic coating is to immerse the coated product in a water-soluble coating as a cathode, and set up another anode corresponding to it. Direct current is applied to the two poles, and the coating is evenly adsorbed on the substrate by the physical and chemical action of the current A coating technique on a coating. Electrophoretic coating requires an electrophoretic coating production line. So what equipment does an electrophoretic coating production line consist of?
A complete set of electrophoresis equipment includes: electrophoresis tank, electrophoresis rectifier, electrophoresis paint ultrafiltration machine, pure water machine, oven curing equipment, integrated hot and cold exchanger, ultrasonic cleaning machine, electrophoresis paint waste paint treatment equipment and so on. These equipment and the equipment and equipment for conveying the workpiece constitute an electrophoretic coating production line. The electrophoretic coating production line is further divided into several types of electrophoretic assembly lines such as manual, automatic, and semi-automatic lines according to different operations.
The manual electrophoresis coating production line requires manual lifting for the entire process. Small investment but labor intensive. The automatic electrophoresis coating assembly line does not require personnel operation except for other processes of hanging and hanging. The automatic line has the highest efficiency and saves workers, but the investment will be relatively high. Some of the semi-automated electrophoresis lines require manual transfer.
If the tank body and the workpiece are relatively large, then automatic line production is basically used. Manual lines generally require only a few simple procedures and equipment. However, manual lines are more labor-intensive and the shipping speed is relatively slow. Generally, a maximum of several thousand products are produced in a day. If the automatic line is simpler, it will cost 500,000 to 500,000. If the requirements are relatively high and the workpiece is relatively large, millions of dollars will be invested. The automatic line is the most labor-saving, and generally tens of thousands of products can be electrophoresed every day.
Electrophoretic coating has fast construction speed, can realize mechanized and automated continuous production, uniform paint film, strong adhesion, and can not be easily applied to the general coating method or poorly coated parts, such as ribbed plate welds and other places can be uniform and flat , Smooth paint film. The paint utilization rate is as high as 95%. Electrophoretic paint uses water as a solvent, which has the advantages of non-combustibility, non-toxicity and convenient operation. The dried paint film after electrophoresis has excellent adhesion, and its rust resistance, corrosion resistance, weather resistance and other properties are better than ordinary paint and general construction methods.
The following specifically describes the equipment included in the entire electrophoretic coating production line:
The electrophoresis tank is a special container for preparing electrophoretic paint and electrophoretic paint color paste. The electrophoresis tank stores the electrophoresis tank fluid, and the coated workpieces are electrophoretic coated and painted in the electrophoresis tank. Other equipment for electrophoresis coating is for the electrophoresis tank service.
2, hot and cold exchanger
The cold and heat exchange machine is a compressor that compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant. It is controlled by a four-way valve, and changes the direction of refrigerant flow through the condenser, capillary, and filter. When the refrigerant changes from gaseous to liquid, Release a large amount of heat; when changing from liquid to gas, it will absorb a large amount of heat, and then exchange with the tank liquid to achieve cooling and heating functions; Hongheshun cold and heat exchanger is specifically targeted at the electrophoretic coating industry The research and development design has strong power, low use cost, and fully automatic temperature control without manual care. It is the most cost-effective temperature control solution for electrophoretic coating industry tank temperature control!
Electrophoresis power is divided into thyristor power and high frequency rectifier power. The ripple coefficient of SCR is relatively low, relatively stable, and the price will be slightly higher. The ripple coefficient of high-frequency rectifier power supply is relatively high, and the price will be cheaper.
4.Ultrafiltration recycling machine for electrophoretic paint
The ultrafiltration system is one of the core equipments in the electrophoretic coating process, and its main functions are:
(1) Recovery of electrophoretic coatings. When using an ultrafiltration machine, because the electrophoretic coatings adhered to the object to be coated can be removed by washing with ultrafiltration, the recycling efficiency can be as high as 95% or more. Reduced sewage treatment volume and costs.
(2) Control of the electrophoresis bath, the conductivity of the electrophoresis bath and the content of impurity ions are controlled through the discharge of the ultrafiltration to ensure the quality of the paint film of the electrophoresis coating.
5, pure water machine
The water purifier is a water purification device that removes or reduces the salts in the water (mainly strong electrolytes dissolved in water) to a certain degree. The manufactured pure water meets the pure water needs of the electrophoresis coating production line process.
RO reverse osmosis pure water equipment, which relies on reverse osmosis to separate the solvent from the solute under pressure. Because the pore size of the reverse osmosis membrane is less than 0.0005 μm, it can effectively remove bacteria, inorganic salts, organic salts, heavy metals, Removal rate of carcinogens such as viruses and pesticides: ≥98% -96%.
6.Electrophoretic paint waste paint processing equipment
This equipment is mainly developed for the separation of paint and water from electrophoretic paint waste paint. The electrophoretic paint wastewater processor can reduce COD, BOD, chromaticity, etc., and mainly uses the dissolved gas water formed by the ejector under a certain pressure in the dissolved gas system. It adheres to the electrophoretic paint in the bath, rises to the water surface with the microbubbles, and forms scum. The electrophoretic paint slag is agglomerated and scraped away on the water surface, and the water is discharged cleanly. Get really removed. As long as the PH value is adjusted and a special polymerizing agent for electrophoretic paint is added, the equipment runs normally after commissioning and does not require special management. It is mainly used for sewage treatment of electrophoretic paint, which is environmentally friendly, energy saving and efficient.
