Introduction to the use of painting equipment:

Dalian metal plastic coating electrophoretic coating is carried out by immersing the entire vehicle body in a tank solution. How to change the transportation method of the vehicle body and the posture of the vehicle body in the tank solution, so that the surface of the vehicle body can be painted by swimming, has always been a difficult problem. The main reason is that the air inside the cavity cannot be completely expelled when fully immersed, forming an "air bag" that cannot be painted. When using a general suspended conveyor chain, the coating surface reaches over 90% At that time, switch to the vertical conveying method (with the front of the vehicle facing downwards) and the swing rod chain conveying method (45 ° inlet and outlet groove). There has been some improvement, but there are still uncoated surfaces. The later developed rotary immersion paint conveying method basically solved the problem of air pockets. The transport device used for electrophoretic coating is composed of a conveyor chain, a hanging frame carrying the vehicle body, and a sled, etc. It should be able to control the posture of the vehicle body in the groove, requiring a constant and stable chain speed, no pulsation, no groove liquid flow marks on the vehicle body, ensuring sufficient strength, and light weight.

Dalian metal plastic coating requires cleaning the spray painting equipment first, pouring the liquid with pre adjusted temperature into it, and measuring its pH value briefly. Due to the prolonged working state of spray painting, the resulting solution has strong viscosity, which can easily affect the electrodes during measurement and cause certain errors. So the staff should regularly clean or replace the contaminated electrodes.

 

If you want to measure the size of the spray paint range, conductivity can be used for testing. In order to ensure the accuracy of the measurement results during measurement, it is necessary to regularly check the instrument and promptly repair any faults found. For the negative panels used in daily production, it is also necessary to prepare some spare ones to avoid unexpected situations where there is not enough spray paint, which may affect the accuracy of the spray painting equipment.

Dalian Metal Plastic Coating Electrolysis: The phenomenon of decomposition of any conductive liquid when electrified is called electrolysis. A well-known example is the electrolysis of water, which can decompose into hydrogen and oxygen. Generally, electrolysis is accompanied by the release of gas on one or two electrodes, where oxidation and reduction reactions occur respectively. During electrophoresis, water undergoes electrolysis, releasing hydrogen gas on the cathode and oxygen gas on the anode. The metal anode dissolves, releasing metal ions.
