First, the production of gold and silver

1, machinery and equipment

Production of gold and silver card machines, most manufacturers use a dedicated wet compound machine; domestic common common Japanese machine, Taiwan machine, Xi'an machine, self-made imitation Taiwan machine.

2, the required raw materials

The most basic materials are: water-based glue, varnish (ie Varnish) or color ink, aluminum (or aluminum foil), white cardboard (or glass card, gray card) and so on.

3, the process

① silver card: in the wet compound machine, the white cardboard (or glass card, gray card) and aluminum (or aluminum foil) with glue; and then in the aluminum film (or aluminum foil) on the surface of a layer of varnish Varnish); and then drying Road drying, winding.

② gold card: in the wet compound machine, the white cardboard (or glass card, gray card) and aluminum foil (or aluminum foil) with glue; and then in the aluminum foil (or aluminum foil) on the surface of a good tune Gold color ink varnish (varnish); and then drying Road drying, winding.

Second, the production of gold and silver card required conditions

1, raw materials must meet the requirements

① aluminum film:

(1) Surface tension above 36Dyn.

(2) good adhesion of the aluminum layer, with 3M600 tape paper, 90 ° stretch, the light can not afford to aluminum.

② varnish (varnish) or gold color ink: with the commonly used solvent color ink, UV color ink layer between the adhesion is good (varnish resin system solubility parameter close to 16.6 (J / ML) 1/2; φ surface tension 35Dyn above.

③ glue: no impurities; no blister; moderate viscosity, strong bond.

④ white cardboard: the corresponding customer, paper density, whiteness, smoothness to meet the appropriate requirements; not damp.

2, the process must have a few conditions

① the installation of the proposed oven temperature is set to 80 ℃, 85 ℃, 95 ℃, 75 ℃; bake should be more than 8M, speed 80 ~ 110M / Min made in the production of the oven, the need to consider the oven temperature, Machine recommended oven temperature set to 65 ℃, 70 ℃, 75 ℃, 60 ℃, bake Road should be more than 6M, speed 40 ~ 70M / Min; to dry film, gold and silver cardboard is not deformed, shiny, product qualified for standard.

② Before cooling, it is necessary to ensure that the cooling device cools down.

③ have ventilation equipment, and keep the flow at any time.
