Furfuryl alcohol and phenolic resin are mixed in a specific ratio to ensure uniform dispersion of furfuryl alcohol within the resin matrix. This step is critical, as it directly impacts the final product’s performance.
Curing Treatment
The mixture undergoes curing to form a stable network structure. Curing can be achieved through heating, pressure application, or chemical cross-linking, depending on the intended application.
Post-Treatment
After curing, post-treatment processes such as drying and cutting are performed to ensure the modified resin meets practical usage requirements.
