0010010 nbsp; 0010010 nbsp; 0010010 nbsp; brushing method is generally used to apply pure water-based sealing glue to the adherends of complex shapes, or to apply to the surface Area without covering the rest with cover. Although the brush coating method requires little equipment and a small loss, the thickness of the coated adhesive film is not easy to control, and the uneven thickness of the film is also easy to foam, which is generally not suitable for rapid assembly work. The brushing method is mainly used for manual brushing and bonding of outer packaging boxes in the packaging industry.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; spray

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Mainly used for large area coating non-uniform surface. The production efficiency is high and the thickness of the adhesive film is uniform, but the solid content and viscosity of the adhesive must be controlled to the extent that can ensure the formation of a uniform coating. Since the fumes formed by solvent spraying may endanger human health, this problem needs to be considered when spraying, and sufficient ventilation conditions must be provided. Suitable for furniture decoration industry, it can bond sponge, leather, cloth and other materials.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; spraying method

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; spray glue is suitable for sofa sponge, foam, fabric, leather, paper, wood board, plastic, PVC, PE, EVA, metal, rubber , Thermal insulation cotton, fireproof board, aluminum plastic board and other materials. The adherend using the glue spray method can be easily removed, and has strong initial viscosity, fast speed, convenient use, and can effectively improve work efficiency. It is generally used for folder-gluing machine, only for high-speed color box edge banding.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Roller coating method

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; It is suitable for the adhesion of flat sheets or films, and can also be used for parts with a width greater than 1. 83 m . The thickness of the coating can be determined by adjusting the pressure roller. Roll coating method can provide extremely high productivity and extremely uniform coating thickness. It is mainly used for large-area coating. The roller coating method can be used in the printing and packaging industry, furniture industry, and decoration industry.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Scraping method

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Use an adjustable slice, rod or rod to control the amount of adhesive deposited on the moving plate left under the blade. The distance between the blade and the surface of the adherend determines the thickness of the adhesive coating. It is suitable for PE protective films and high-adhesive tapes of various metal plates, and can also be used for wall coating of latex paint.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; screen coating method

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The screen coating method is a manual operation method. This manual technique can ensure that the coating area or structural space is a viscous coating. In this case, low viscosity adhesives are easy to handle because they can be quickly distributed through the screen to the work surface to be coated, but this method is only suitable for relatively thin adhesive films. The screen coating method is suitable for the window sticking process of color boxes.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; dish coating

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Dish coating is suitable for regular high-speed glue-gluing of boxes. In the straight-line box glue sealing, it has fast speed and even glue Features such as plastic saving and easy operation. Pure water-based sealing glue is suitable for color box edge sealing of various regular or special-shaped boxes such as daily necessities, cosmetics, pharmaceuticals, electronic products and so on.
