Three-way composite machine to avoid the bonding of the final product of several skills

InTriple laminating MachineIn the course of use, when the coating is increased, the two basic materials are difficult to combine, too little or no coating on the coating surface. Temperature too high or too low will affect the bond fastness of the composite film. When the coating substrate is dry, the heat temperature is too high, or high temperature cooking. The surface of the adhesive can be carbonized, thereby damaging the adhesive adhesion ability. Drying temperature is too low, the curing is incomplete, the adhesion is poor, the bond viscosity is poor, the composite material is fragile, after a period of time, the compound membrane is easy to form the bubble, destroys the composite product quality. As a professional manufacturer of China's composite machinery, we provide three kinds of solutions, the following for you to introduce.

     

WhenTriple laminating MachineWhen the coating is increased, the two basic materials are difficult to combine, the coating is too small or the substrate surface is not coated. We can use the deep net roller, or by increasing the pressure of the rubber roller, reduce the contact pressure of the blade and the roller, and increase the coating on the substrate surface. For some plastic film substrates, corona treatment can be carried out before coating to reach HP's surface, thereby enhancing the adhesion ability of the matrix adsorbent, thus increasing the surface coating.

Dry-type laminating machine mainly choose the right drying temperature, too high or too low will affect the bonding fastness of the composite film. When the coating substrate is dry, the heating temperature is too high, or high temperature heating. It causes the surface of the adhesive to be carbonized, thereby damaging the adhesive adhesion ability. Drying temperature is too low, supplier information, curing incomplete, binder, viscous viscosity is poor, complex instability, after a period of time, easy to form bubbles, composite film damage composite quality. Of course, we can choose High-temperature, high-temperature adhesive digital printing presses for high-temperature drying, such as polyurethane adhesives.
