What are the requirements for temperature in the process of making anti-static aluminium foil bags

In the production process of anti-static aluminium foil bags, the temperature can be divided into two stages as follows: .

1. Heating up stage

As long as the steam is sent to the curing room for 1 ~ 1.5 hours, the heating time should be shortened.

2. Constant temperature stage

The constant temperature stage is an important stage in the growth of strength due to hydration and hydrothermal synthesis of the blank. With the increase of the constant temperature time, the more the water material gathered more and more, strength increase home also more and more quickly. However, after a certain period of time, the strength increase begins to slow down. Different raw material formulation, different production processes, different manufacturing billets, there is a relative excellent temperature control time.

For example, in 96 ~ 100 ° C damp heat conditions, constant temperature time of 8 hours in spring and autumn, 7 hours in summer, 10 hours in winter. Anti-static aluminum foil bag temperature reduction link is great when the indoor space design is not enough, the door should be opened, should be cooled, which in turn causes the temperature difference of the plastic film ground stress, and then be able to pull Shen surface layer, produce micro cracks. So, to control the speed of cooling, every 30 minutes of cooling should not be higher than 10 ° C; maintenance room temperature difference between the outside of the room is not greater than 30 ° C, finished products can only be out of the room.
