Correct protection analysis of Dalian metal plastic coating:

Dalian metal plastic coating dries slowly in winter and is prone to sagging, or the primer is not dry, which affects the assembly line operation. Water based coatings, including water-based metal pigments, and aluminum silver paste itself dry slowly, making natural drying difficult in winter. How to prevent sagging and other phenomena? Actually, doing electric hot air blowing treatment and adding hot air circulation to the automatic line can effectively improve it. Coatings contain benzene derivatives such as benzene, toluene, xylene, etc.

If the ventilation in the workshop is poor, the operators do not wear protective equipment correctly, or the protective equipment fails, it may cause chronic poisoning or acute poisoning, and even occupational diseases. For components such as fans, pumps, motors, and filters that are prone to malfunctions in conjunction with spray painting equipment, it is recommended to install alarm devices with sound or a combination of sound and light, and interlock them with the power source for spray painting operations. The correct spraying trajectory should be kept perpendicular to the surface of the workpiece.

When coating metal and plastic in Dalian, the distance between the spray gun and the sprayed surface is generally 15-30cm according to the angle of the coated surface. To obtain a wetter, darker, and thicker coating, the distance can be closer; To obtain drier, lighter, and thinner coatings, the distance can be farther. Looking directly at the fullness of the paint film, if the paint film is too thick, it will feel cloudy, the paint color will not be bright, if the paint film is too thin, the paint surface will not be bright enough, and the paint color will be dark. A paint film with good fullness feels like there is a layer of oil floating on the surface of the paint.

The front facing paint surface should have a mirror effect, and the front and diagonal paint lines should be even with the original factory paint lines. In addition, it is impossible to have no paint lines, even after polishing, there are paint lines on the original car paint, and the effect is not good without paint lines. When the air in the spray painting or baking paint room is unfiltered or improperly filtered, and some technicians' construction is improper, dust will accumulate on the surface of the paint, forming pockmarks, commonly known as "dirty spots". Gently touch the sprayed paint surface with your hand to feel if there are any bumps or foreign objects present. Check if there is paint color on the rubber parts near the paint spraying area. If there is flying paint, the car owner can request the manufacturer to wipe it with gasoline or cleaning solution.

Dalian metal plastic coating may experience flying paint due to inadequate coverage by workers during the construction process. Clean and soft cloths or sponges should be used to scrub vehicles to prevent the mixing of metal shavings and sand particles. Do not use dry cloths, towels, or sponges to scrub vehicles to avoid leaving scratches. When wiping, gently wipe from top to bottom in the direction of the water flow, without drawing circles or wiping horizontally. For some highly corrosive traces (such as asphalt, bird droppings, insects, etc.), they should be removed in a timely manner.
