Vacuum plating aluminum foil metal transfer agent and its manufacturing process
At present, the tobacco industry, packaging with aluminum foil by rolling aluminum foil composites. Need rolling equipment and rolling aluminum raw material imports expensive, high production cost, cost a large number of foreign currency. The invention solves the technical difficulties of the new technology of vacuum aluminum foil production and the new technology of producing aluminum foil paper can completely replace the traditional production process, and has significant economic benefit and social benefit.
Aluminum foil metal transfer agent is mainly composed of starch, calcium hydroxide, sodium hydroxide, rosin, sodium chloride concentration...... And other materials, the value of pH is greater than 12.
A method for the use of new technology for production of vacuum aluminum foil aluminum foil in the metal transfer agent, which is characterized by:
Vacuum plating aluminum foil metal transfer agent of formula (weight percentage): starch 12 to 14.5 hydrogen peroxide concentration (30%) of 0.1 ~ 0.15 aqueous solution of calcium hydroxide to 73 to 77.3 sodium hydroxide concentration (30%) from 7.8 to 9.25 concentrated rosin extract 0.5 ~ 1 chloride wax 0.5 ~ 1.0 alum 0.5 ~ 1 borax 0.8 ~ 1.5 sodium thiosulfate 0.5 ~ 0.61
Vacuum plating of aluminum foil metal transfer agent pH value greater than 12.
