During the actual use of formaldehyde, how should polyformaldehyde be treated? Can it be converted into formaldehyde again?

In the actual use of formaldehyde, polyformaldehyde appears due to static storage under low temperature conditions for a long time. How should we deal with it? Can it be converted into formaldehyde again?
1. Use equipment to store it for four weeks. It is best to use steam to heat it. 2. Add water with a temperature of about 30 and circulate it slowly to dissolve.
When heated to above 50 degrees, depolymerization will slowly begin.
Adding steam to the storage tank for heating can prevent polymerization
