Plywood Phenolic Film Impregnation Line


Plywood Phenolic Film Impregnation Line

The plywood phenolic film impregnation line starts with the preparation of the phenolic resin mix, which is then applied to a film or directly onto paper. This coated paper or film is then dried to reach a tacky stage suitable for lamination.

Phenolic Film Impregnation Line sheets are fed into the line where the phenolic film is applied. Through the lamination press, heat and pressure are applied to ensure a strong bond.

More Details of Plywood Phenolic Film Impregnation Line


  Primary Impregnation Station

For Primary Impregnation Station. After paper pass to impregnation machine, paper’s lower surface is single-glued by back coating roller. The size of wrap angle on back coating roller is adjustable by technological requirements. Resin liquid impregnate into paper’s lower surface and remove air inside paper. To remove air inside paper thoroughly, there has breathing device after back coating device. Breathing device is equipped with rubber bending roller on both ends.


Drying Section

Dry the impregnated paper. The heating medium of dry section is heat transfer oil. According to technological requirement of drying, each section of drying zone has one temperature zone and can separately set its operating temperature and is automatically controlled by temp control system to keep real temperature and setting temperature stay at same. Generally the temperature is controlled between 100~200℃. Each section has one wet-exhaust connector which the size of connector is controlled by manual-operated ventil

Advantages of plywood Phenolic Film Impregnation Line

Improved Durability: The primary advantage of using a phenolic film impregnation line is the significant enhancement in the durability of plywood. The phenolic resin that coats the plywood during the impregnation process provides a protective barrier that increases resistance to moisture, chemicals, and wear.

Enhanced Moisture Resistance: Phenolic film impregnation seals the plywood, reducing its susceptibility to water absorption. This moisture resistance prevents warping, swelling, and other water-related damages, extending the plywood’s lifespan and maintaining its structural integrity over time.

Increased Fire Resistance: Phenolic resins are inherently flame retardant. When applied to plywood, they enhance the material's ability to withstand fire, slowing down the spread of flames and contributing to safer building materials, particularly in fire-sensitive areas.

Cost-Effectiveness: Although the initial investment in a phenolic film impregnation line can be substantial, the long-term savings are significant. The extended lifespan and reduced maintenance of the plywood reduce overall costs over time. Additionally, the efficiency of the impregnation process minimizes waste and maximizes output, further enhancing economic efficiency.

Environmental Benefits: Modern phenolic film impregnation lines are designed to be more environmentally friendly. They use less energy and can incorporate recycled or eco-friendly materials in their processes, aligning with sustainability goals of many companies and regulations.

Quality Consistency: The automated nature of the impregnation line ensures consistent application of the phenolic resin, leading to uniform quality across all treated plywood. This consistency is crucial for industries where standardization is key, such as in construction and manufacturing.

How to Maintain Your Plywood Phenolic Film Impregnation Line

Importance of Maintenance Regular maintenance of your impregnation line not only ensures consistent quality in your products but also minimizes downtime due to equipment failures.

Cleaning the Line Cleaning is fundamental to maintenance. Remove any debris, dust, or residual materials that could affect the machine's function.

Inspecting Mechanical Parts Regular inspection of mechanical parts like gears and rollers is necessary to identify wear and tear early, preventing more significant issues later.

Checking Electrical Systems Electrical systems should be checked for any signs of wear or failure. This includes inspecting wiring and connections and testing control systems.

Lubrication of Components Proper lubrication reduces friction and wear on moving parts. Use the recommended lubricants and follow the manufacturer’s guidelines for application intervals.

Replacing Worn Parts Identify and replace worn or damaged parts to maintain the operational efficiency and safety of the line.
