Process for reducing formaldehyde content from cationic melamine-formaldehyde resin solution |
| abstract |
The present invention generally relates to a process for reducing formaldehyde content from cationic melamine-formaldehyde resin solution. Said process comprises the steps consisting of charging a starting solution to an ultrafiltration membrane system, separating said starting solution into a concentrate solution which mainly comprises cationic melamine-formaldehyde resin of high molecular weight, formaldehyde and water, and a permeate solution which mainly comprises cationic melamine-formaldehyde resin molecules of low molecular weight, formaldehyde, acid compounds and water and treating the permeate solution to reduce the free formaldehyde content of the permeate. |
