PE protective film temperature requirements during the production process

- Sep 07, 2020-

1. Heating stage

Under the premise of ensuring that the PE protective film blank is not affected by steam, the heating time should be as short as possible, as long as the steam is continuously and uniformly fed into the curing room for 1 to 1.5 hours.

2, constant temperature stage

The constant temperature stage is an important stage where the green body undergoes hydration and hydrothermal synthesis to increase the strength. With the extension of the constant temperature time, the more the hydrate is aggregated, the more rapid the strength growth. But after the constant temperature reaches a certain period of time, the strength growth begins to slow down. Different raw material ratios, different production processes, and aerated blocks produced have an optimal constant temperature time corresponding to them.
