(1) film activation
The drape water transfer film on the surface of the tile to transfer water, graphic layer up, keep the water in the water tank cleaning, and in a neutral state, with the activator in the graphic surface evenly spraying, the graphic layer activation, easy separation and carrier film. Activator is a kind of organic mixed solvent based on aromatic hydrocarbons. It can dissolve and destroy polyvinyl alcohol rapidly, but it will not damage the picture and text layer, make the picture and text be free. The principle of film activation is shown in figure 3.
(2) water drape transfer process
Will need water transfer items along the contour gradually close to the water transfer film, graphic layer will be under the pressure of the water slowly transferred to the product surface, adhesion due to adhesion of ink and printing materials or special coating inherent. Transfer process, the substrate and water coated film laminating speed to maintain uniform, avoid film wrinkles and make graphic unsightly. In principle, we should ensure proper stretching of the picture and text, and avoid overlap as much as possible. In particular, the overlap and excessive overlap can make people feel confused. The more complex the product, the higher the demand for *.
Water temperature is an important parameter affecting the quality of transfer, the water temperature is too low, may cause the dissolution of substrate film, water temperature is too
high, and easy to cause damage to graphics and text, causing deformation of text. The automatic water temperature control device can be used to control the water temperature in a stable range. The mass of the workpiece for the shape is relatively simple, unified, and water transfer equipmen
