Background technology
Air knife spraying binder is a kind of water soluble acrylic resin, is the connection for being specifically applied to the spraying printing of air knife machine
Material.Air knife spraying be very different with traditional coating and printing mode, air knife spray be by the air-flow of middling speed or high speed with
About 45 ° of angle is sprayed onto on the material applied being coated on lining roller, and air-flow produces shearing force to paint film makes excess coating material
It is removed into liquid or gaseous state, so as to obtain the smooth printing sample of surfacing.
It is 9 ~ 11 seconds that air knife, which sprays appropriate viscosity of the binder when being used with ink, and traditional binder needs add a lot
Diluent can just make to adjust to appropriate viscosity with black viscosity, so that resin content reduces in pearl lusting printing ink, this is largely effected on
