Crystal drops of glue labeling process - The crystal drops of glue labeling manufacturers in guangzhou

Crystal drops of glue labeling process as signs, stickers, labels the development of packaging industry, crystal drip glue labeling products have been widely used to all kinds of products. Such as handicraft, working number, badges, key chain, nail clippers, electrical appliances, furniture, sanitary ware, kitchen utensils and appliances, door, furniture and other products LOGO, in recent years many car decoration and LOGO are crystal drops of glue labeling process. Crystal drops of collagen materials generally optional epoxy resin, in order to improve the quality of the products and competitiveness, more use of uv PU adhesive. PU rubber is a kind of modern plastic adornment material, ingredient aliphatic isocyanate, all kinds of polyether polyols and related catalysts, after curing for soft anti-uv elastic resin. Applicable to all kinds of substrate, such as: self-adhesive, PVC, laser label material, synthetic paper, drawing materials, as well as copper, zinc alloy, aluminum, stainless steel, nickel, plastic, organic glass, fiber and a series of signs, labels, stickers. To produce equipment and consumable: 1, digital electronic scale, vacuum deaeration machine; 2, a glue platform ( Glass) ; 3, baking box; 4, glue plastic cup, used for stirring rods, plastic glue pot, double-sided tape, cleaning agents, anhydrous ethanol; 5, syringes, and different types of needles. Automatic equipment drops of glue, glue, glue, glue quantity size thickness, speed glue, glue can parameter setting time, stop time. Crystal drops of glue labeling handmade process: 1, first of all, ready to drop the rubber material, 60 degrees in the oven preheating treatment, aims to remove surface moisture; 2, after going to wet glue material flat on the level of consistent work station glass waiting for glue; 3, according to the dosage, use clean water cup, accurate measurement. Will a component b, according to the required ratio mixed stirring evenly; 4, and then with a good mix in vacuum oven, open pump, removing the air bubbles in the mixture under the vacuum state; 5, clean in the needle, after defoaming crystal glue to the needle, and then measuring and drip evenly on the prepared surface of stickers, labels, advertising, general crystal rubber thickness 2 mm, allow it to flow naturally flat. Note that the above process are controlled within 30 minutes, in order to avoid glue solution viscosity increased. 6, substrate 3 - after the drip crystal glue 5 minutes, observe rubber surface with and without bubble or dust particles, such as have the tiny bubbles and hearing the available pin prick, if discover to there is not a corner flow crystal glue to the place, with a pin to extradition; 7, pouring good crystal drops of glue labeling, at 20 ℃ - At room temperature curing 10 to 30 ℃ 24 hours of hardening, or into the baking box effect is better; 8, the thickness of the thin substrate, line is not obvious, pouring, easy to cause the crystal glue overflows, to 2 mm thickness can be difficult. 1 - the need to control viscosity, can be placed 2 hours, in order to improve the viscosity, adapt to thin crystal glue pouring.
