Abstract: |
Coating system is the kernel of solventless laminator and the difficulty in the manufacture process.Precise control of coating weight(CW) is the key of solventless lamination, which restricts the development of solventless lamination, and the direct factors of making production achieve the best.Through the determination of CW,the various influence factors are determined. The technique and characteristics of solventless lamination are introduced.Structural characteristics about coating system and transfer discipline of solventless laminator are discussed.Through testing CW,transfer rules in the different speed ratios are analysed with the software of MATLAB.In accordance with coating inhomogeneity, the change of the viscosity of adhesive is the main factor.The basis to identify the quality of lamination products and know the right CW well are provided,which meet the coating requirements of solventless laminator.
