I. Log material cutting and sawing.
The raw material is based on the logs for rotary cutting from the logs in accordance with a certain layer thickness for horizontal cutting rotary cutting, according to the size of the film faced plywood before cutting into the same proportion of the wood layer, and the wood layer surface impurities for removal, impurities can affect the bonding fastness of the late glue.
2. air-drying treatment.
Cutting and rotary cutting after the veneer contain relatively large moisture, therefore, large-scale production to be dried through the wood drying machine, drying the wood layer is relatively brittle, therefore, to be placed naturally for about 3 days, can ensure the toughness of the board. Or you can use direct open-air sunlight for natural wind drying treatment.
3. over glue, a row of board processing.
The Film Faced plywood is used in a multi-layer wood panel using the glue coating method of bonding together, set up a special glue roller, the wood panels through the glue filling machine, the front and back of the board will be evenly coated with glue layer, will be coated with glue layer of wood panels flat placed on the surface of the template above, evenly spread 7-13 layers (according to production requirements) can be. Then the Film paper will be placed on both sides for the next step of hot pressing treatment.
4. Cold pressing, hot pressing treatment.
After gluing and laying the plywood layer, it is pressed flat by the hot pressing process. Traditional heating is used when the boiler water is transferred to heat for heating, modern equipment room uses electric heating, after flattening, can increase the denseness of the Film Faced Plywood production, molding is more regular, improve the quality of the use of the Film Faced Plywood. Adopting the process of pre-pressing and then hot pressing, the higher degree of reducing the chance of misalignment of the blank, and then applying reasonable pressure and temperature hot pressing, ensures that each construction Film Faced plywood has excellent gluing strength and hardness.
5. Spraying edge, trimming packaging treatment.
After the hot pressing treatment of the Film Faced Plywood, there will be a little bit of the inner layer of wood panel material misalignment and edge irregularity, using a carving knife to cut the excess plate, and spray anti-corrosion paint, anti-corrosion paint is an important factor to ensure the service life and storage time of the construction template. Film Faced Plywood production has the advantages of light quality, withstand gravity, smooth surface, etc.
6. Test to go to the defect Film Faced Plywood
After the finished product of the plywood to factory inspection, pick off unqualified with defects not thick enough plywood.
