Epoxy floor paint has the characteristics of anti-corrosion, wear resistance, anti-skid, little pollution and strong decoration. It has been widely used in industrial epoxy floor and environmental requirements. Due to the influence of construction quality and environmental factors, some quality problems have arisen: a. Colouring problem. Colouring refers to when a color primer film is applied. There are several main reasons for discoloration of the surface coating when topcoated with another color: the primer is not completely dry, the color difference between the primer and the topcoat, and the paint contains variegated substances. b、起皱、针眼、鱼眼。
B, wrinkle, needle eye, fish eye.
C. Paint more beautiful, refers to the surface of the film color is not uniform, there are spots and color disorder, the reason is due to the construction process, the face of the ingredients improper and uneven application.
D, surface whitening, refers to the completion of construction operations, surface coating of the phenomenon of whitening, there are several reasons: excessive humidity in the air, the drying process of the coating used too much fast drying agent. The main reason for wrinkling on the surface of the coating is that the drying speed of the inner and outer layers of the coating is not uniform, which causes the surface to fold up, and the needle hole is caused by the solvent exerting too fast, the lacquer liquid supplementing is not timely, and the fish eye is caused by the mixture of the coating or the external impurities, which leads to the uneven adhesion of the coating.
E. Roughness and cracking. Roughness refers to the appearance of granular substances of different sizes on the surface. The main reason is that the coatings contain insoluble impurities and external dust. Surface cracking is caused by the quality problems of raw materials and construction, resulting in a decrease in the adhesion of the paint layer, under the influence of external forces, the phenomenon of peeling cracking.
