Precautions for the production of pharma aluminum foil

Edit:Mingtai Date: 2019-08-09 14:38
There are two common types of pharma aluminum foil on the market, 8011 aluminum foil and 8021 aluminum foil. The thickness of 8011 alloy is generally less than 0.05mm, and the thickness of 8021 alloy is greater than 0.05mm. The main production processes for the manufacture of pharma aluminum foil are: blank inspection - hollow rolling - partial partial rolling - combined furnace rolling - rolling finished products - cutting furnace annealing - finished packaging. The surface of pharma aluminum foil requires no oil, no bright crystals, no black lines, no pinholes, no yellow spots, no fringes, etc. In the production process, there are several main points for the control of surface and performance:
1. Firstly control the quality from the source and strictly test the blank;
2. Then, in the process of rolling the pharma aluminum foil, the surface quality is controlled by roller cleaning and roughness control, selecting rolling oil, reducing the viscosity of the rolling oil, controlling the running speed of the machine, and the like;
3. In the process of cutting pharma aluminum foil, it is necessary to ensure that the edges of the edges of the aluminum alloy are neat, and no quality problems such as ruffles can occur;
4. Finally, during the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the foil to ensure oil cleaning.
With the development of the pharmaceutical industry, pharma aluminum foil has high moisture resistance, barrier properties, chemical resistance, chemical stability, health, application increasing proportion, appearance and quality requirements are getting higher and higher, and the market prospect is very broad.
