TB-1500 Surface modification coating method for coating mach

At present, the surface modification methods often used in the industry are corona discharge, plasma treatment, surface grafting polymerization, surface coating method and so on.

Corona discharge treatment and corona discharge backing. A method of making the surface of polyolefin, such as polyolefin, by corona discharge, to make it more acceptable for printing ink, drilling mixture, and coating.

Surface graft polymerization is the first through various means to produce free radicals on the membrane surface and membrane surface free radicals and further modified monomers or functional groups, so as to achieve the purpose of modification. The characteristics of surface grafting polymerization include: functional groups or functional substances are bonded to the surface of microporous membrane by chemical bonds. Functional materials will not be lost during the application of membranes.

  
  After comparing the above surface treatment methods, the modification effect of the surface coating on the surface of the coating machine is the most ideal.

The principle of surface coating method is coated with a layer of film on the surface of the resin containing polar groups, higher surface tension, so that the formation of a transition layer of film surface, in order to improve the adhesion of ink, aluminized layer. The coating resin plays a bridge role between the thin film substrate and the sticky material. It has affinity to the film substrate and compatibility with the adhesive. Therefore, the coating can be organically integrated into one, which can meet all kinds of requirements for deep processing. The coated BOPET film has excellent compatibility with most ink including water-based inks, and has good printability and clarity.

　　Through the above understanding, you should have a more understanding of coating machine, laminating machine, gravure printing press, Slitter, if you have other questions, you may contact our online customer service:+86-13958857367。
