一分彩Adhesive properties and effects of polyethylene anticorrosive tape

一分彩    Even with the emergence of polyethylene anticorrosive tape and non-adhesive soft board materials, most of the soft board materials are still joined by means of an adhesive, because it must meet the manufacturing characteristics of the soft board, so the adhesive must conform to the copper skin. Compatible, suitable fluidity, withstands the operating mode of the flexible board, does not cause board peeling, is not easy to deteriorate, and is resistant to flames.

一分彩Generally, the adhesive is coated on the base material of the flexible board, and then combined with the metal layer. The laminating industry can use a laminator or a continuous roller to press the laminating material. . Adhesives often used for soft board materials include polyester resins, modified epoxy resins, acrylic resins, etc. Polyamide resin materials such as stickers are the adhesive systems expected for multilayer boards.

   Different substrates and different end packaging requirements, so as to have different sizing amounts. The simple plastic / plastic composite of Yiwu tape can be a little less, 2.5-3.0 grams per square meter is enough. If it is a composite material containing aluminum foil, and it needs to resist medium corrosion, it needs 3.5-4.0 grams per square meter. For high-temperature cooking, in addition to the extremely important appearance tension, 4.5-5.0 grams per square meter is required.

It is the manipulation of residual solvents. The amount of residual solvent not only affects the odor and the cleaning function of food, but also has a significant impact on transparency and peeling force. Residual solvents must not exceed 10 mg per square meter; however, they can be controlled below 5 mg per square meter. Therefore, in the selection of composite technology, it is necessary to determine from the factors of solvent variety, drying tunnel temperature, start-up speed, air volume and air volume.

一分彩    The fourth is ripening conditions. Because the adhesion of polyethylene anticorrosive tape is a two-component reaction type, it is necessary to have appropriate conditions to allow the main agent and curing agent in the adhesion of polyethylene anticorrosive tape to fully react and reach the bonding effect. Functional polyethylene anticorrosive tape that can react chemically with vivid elements on the outside of the substrate must have a certain temperature and time.
