Melamine Two Step Impregnation Line
A two-step line combining primary impregnation and secondary coating for controlled production of melamine decorative paper and phenolic film.
Core process capabilities
Production applications
Equipment and process details
Final parameters and system boundaries are confirmed against materials, process targets, capacity and site conditions.
Melamine Two-Step Impregnation Line is used to produce melamine-impregnated decorative paper through a first impregnation stage and a second coating stage, with front and rear drying ovens for independent drying and pre-curing control.
This process allows precise adjustment of resin pickup and surface film formation, making it suitable for stable mass production of impregnated papers forMFC and Shuttering Plywood.
Customization | Line configuration, including oven zone number and unit requirements, can be recommended or customized based on base paper basis weight and dimensions, production capacity targets, and finished paper requirements. |
