According to the construction characteristics of plastic spraying coating and the functions of each layer, the coating structure can be divided into three parts: 6sq. Net K # WV5R. Y \ P。
(1) Base oil (primer and primer)
. # {zq # fmdki-quality-SPC, Six Sigma, TS 16949, MSA and FMEA primer are the first coatings applied on the base. It penetrates into the interior of the matrix, enhancing the strength of the matrix, sealing the surface of the matrix, eliminating the harmful factors of the surface of the matrix on the coating adhesion, and increasing the bonding force between the skeleton and the matrix.

Intermediate coat is a unique forming layer of plastic spraying and the main component of plastic spraying. Spray it on the base oil with a special large-caliber spray gun and then roll it to form a three-dimensional pattern, which is full of texture, novel and beautiful. The skeleton has enough bond strength to strengthen the building. At the same time, the skeleton is the main component of the plastic spraying coating, which increases the durability, water resistance and strength of the plastic spraying coating.

(III) Topcoat (topcoat and topcoat)
V7\FY\B The surface oil of Six Sigma Quality Forum is the surface of plastic spraying. Various light-resistant color pigments are added to the surface oil to make the plastic-sprayed coating have a soft color. According to different indoor and outdoor requirements, smooth and flat coatings can be sprayed. Surface oil can beautify the appearance of plastic spraying and improve the durability of coating.
Spray painting and plastic spraying are the main ways of industrial surface decoration today. In order to protect the environment, 1982 invented plastic spraying. After 20 years of development, no more than 5% of enterprises now use plastic spraying. Mainly because of the difference between painting and plastic spraying:
● Spray painting is better than spray leveling.
The molecular structure of solvents, additives and resins used in spray painting is of great help to leveling. But there is no plastic spraying, so it often has an orange effect.
● Painting can be repaired.
In the process of painting, pockmarks or scratches caused by too many paint films can be repaired at any time, because the paint has the function of recoating. And plastic spraying is not.
● The flexibility (curvature) of spray painting is better than that of plastic spraying.
Spray painting can bend 1mm, or even t-bend, but plastic spraying is not acceptable.
● The painting is rich in decoration.
The appearance color of inkjet printing is dozens of times that of plastic spraying, and the same material can be made into different effects. Such as plastic, wood, paper, cloth, leather and other non-metallic materials can be made into aluminum effect.
● The hardness of painting is the same as that of plastic spraying.
Plastic spraying pretreatment has low cost and faster speed than plastic spraying.
● Plastic spraying must be baked at high temperature.
Plastic, wood, paper, cloth and leather can't be baked at high temperature.
● Spray painting can be delivered quickly, even if it is a small batch or special requirements, it can meet customer orders to the maximum extent.
Compared with plastic spraying, the surface quality of spray painting is easier to overcome the defects of substrate and meet the quality requirements of customers. However, if the plastic spraying surface is not handled properly, it is more likely to produce pitting defects (bubbles).
