Vacuum plating aluminum foil metal transfer agent and its manufacturing process
Currently the tobacco industry, the packaging with aluminum foil by rolling aluminum foil composite. The need to import expensive equipment and rolling aluminum foil rolling raw materials, high production costs, spend a lot of foreign exchange. The present invention solves the vacuum plating aluminum foil production of new technology of technical difficulties, so that aluminum foil production of new technology completely replace the traditional production process, there are significant economic and social benefits.
Formulations of metal aluminum foil transfer agent mainly composed of starch, calcium hydroxide, sodium hydroxide, and concentrated rosin, sodium chloride and other materials ......, PH value greater than 12.
A method for the production of aluminum foil aluminum foil vacuum plating metal transfer agent used in the new process, which is characterized by:
Vacuum plating metal aluminum foil transfer agent formulation (percentage by weight) of: 12 to 14.5 Starch hydrogen peroxide (concentration 30%) 0.15 0.1 ~ 73 ~ aqueous solution of calcium hydroxide 77.3 sodium hydroxide (concentration 30%) was concentrated 7.8 ~ 9.25 rosin December chloride paste from 0.5 to 1 0.5 to 1.0 0.5 to 1 borax alum 0.8 ~ 1.5 0.5 ~ 0.61 sodium thiosulfate
Vacuum plating aluminum foil metal transfer agent PH value greater than 12.
