Factors affecting the bonding degree of the finished products of the Composite Machine

  Web compound machine is a kind of machine which can compound two or three layers of web paper. The web can be directly cut into the required specifications of paperboard through preheating, gluing, pressing and other processes on the laminating machine. It has high efficiency and is very suitable for mass production. It is an ideal equipment for producing double-layer or three-layer industrial paperboard.

Composite Machine

  So what are the reasons that affect the bonding fastness of the composite machine?

  1. If the drying temperature is too high or too low, the adhesion fastness of the composite film will be affected. When the coating substrate is heated too high or cooked at high temperature, the surface layer of the adhesive will be carbonized, which will destroy the bonding ability of the adhesive. After curing, the composite film is not easy to form after a period of curing.

  2. Because the compound pressure of the Composite Machine is too high or the pressure at both ends of the composite roller is uneven, the surface of the composite film is wrinkled, resulting in the formation of an empty tunnel at the wrinkle after lamination, which affects the bonding fastness of the finished product. The bonding force can be improved by properly increasing the composite pressure.

  3. Too little glue or no adhesive on the surface of part of the substrate will lead to the difficulty of bonding between the two substrates. The roller with deep mesh hole can be selected, or the rubber roller pressure can be increased and the contact pressure between the scraper and the anilox roller can be reduced to increase the amount of glue on the surface of the substrate. In order to improve the bonding effect and quality of the composite products, it is necessary to avoid foreign matters, dust and other impurities adhering to the adhesive or the composite surface of the substrate.
