Low-molecular-weight treatment methods after vinyl removal
Thread Content
Seeking help: The low-molecular-weight substances resulting from the vinyl removal process in the company cannot be dealt with. Does anyone know how to handle them? Also, how can yellowing of the color of these low-molecular-weight substances be resolved? Thank you.
To address the issue of being unable to handle the low-molecular-weight substances resulting from vinyl removal, the following methods can generally be employed: 1. Carry out a cracking reaction； 2. Use a filter to remove low-molecular-weight solids from the solution ； 3. The low-molecular-weight compounds are separated from the solution using chemical precipitation. Furthermore, the problem of low-molecular-weight chromatic yellowing can be addressed by precisely adjusting and resetting reaction conditions, filtering out pigments, or adding antioxidants
